Book Report Writing Template Essay

The following book report format template is appropriate for students at the pre-college level who are required to write a report about a book they have read. For the type of book summaries applicable to college and university level (undergraduate and post-graduate), as well as for business and professional situations, you can check out the following book summary sample. 1. Introductory Paragraph The first sentence should state for which instructor and class the book-report is being written. The second sentence should state the title of the book and the author’s name. The third sentence should tell how many pages the book has and the name of the publisher. The fourth sentence can state basic bibliographic information about the book. Bibliographic information means not only the author and title but also what company published the book, what year it was published in and any other relevant information such as the edition and if the book has been translated, simplified or abridged. (see copyright page and the back of the title page. ) The next sentence should state the reason(s) you decided to read this book. Why did you choose this particular book? Typical reasons might be: You like the author. You like this type of book (i. e. mystery, western, adventure or romance, etc. ). Someone recommended the book to you. It was on a required reading list. You liked the cover. These reasons do not have to be complex. Most people choose the books they read because they like the author or somebody recommended it to them. If you chose the book because you like the author, then state why you like that author. An optional sentence can be used if the cover (back cover) of the book gives you any additional information then add a sentence with that information. Was the book a best seller? Are there X million copies in print? Did it win any major awards? 2. Main Character(s) Paragraph The first sentence of this paragraph should state who the main character or characters of the book are, and why they are important. Refer to this person or these persons as the Main Character or Main Characters. You will need at least a complex sentence for this, and probably more than one sentence. 3. Other Characters Paragraph You should compose at least one sentence for each of the other prominent or important characters in the book. State the name of each of the other important characters, and the key role that each one plays in the book Most books have five or six prominent characters besides the main character, so simply listing each one and stating their role in the book will give you a good sized paragraph. 4. Plot Summary Paragraph This is perhaps the hardest paragraph to write in five sentences or so. If you have to write a bit more don’t worry. Here are the main points to cover: State the type of book (Mystery, Western, etc. ). What place or country was the book set in? What time period was the book set in? (19th century, the present, ancient Rome, the 23rd century). Other physical locations which are important, like: ships, airplanes, houses, or buildings. Other notable attributes of the book. (Was it violent, scary, fast paced, etc. ). What is the main character trying to do? What is the outcome of the book? etc. Make sure you cover all of the major parts of the plot. You might have to go back through the book, chapter by chapter, and make a few notes. 5. Personal Impressions and Conclusion Paragraph Simply talk about what you liked or did not like about the book. Use this paragraph as your conclusion. It should summarize your overall impressions of the book and bring the report to a close. Start with a sentence that states that you are now writing a conclusion. (For example: â€Å"My final thoughts on ‘A Fine Balance’ are that it is a fascinating book but I am not entirely sure if I completely understood the thematic message of the book. † Restate your reasons why you liked and/or disliked the book using different words. Write two sentences that talk about the books good points and weak points. Write a sentence or two about what you learned from the book. Close with a sentence that states whether you would recommend the book to others. Don’t be afraid to give your own honest impressions of the book. After all, if you’ve read the book thoroughly, you are entitled to your own interpretation of it. Typically, your book report should not exceed two double-spaced pages, and it should be somewhere between 600 and 800 words in length.

Conflicts in “Ashes for the Wind” Essay

In the short story â€Å"Ashes For the Wind† by Hernando Tellez, the author uses conflicts to develop the theme that sometimes we have to sacrifice our life to fight corruption. Juan, the protagonist, is a tenant who lives a peaceful life in the village with his wife Carmen and a new born baby. He involves in an external conflict when the corrupt government orders his family to move out of their own place. At the beginning of the story, Arevalo visits Juan’s farm house and tells him â€Å"it would be best for you to clear out†. He then recalls his unpleasant encounter of the same man and a policeman in town; they treat him unfairly. With the policeman carrying whip, and others refusing to sell him oil, Juan senses he is in a bad situation. Moreover, Juan’s external conflict causes his internal conflict since he now faces the dilemma of whether they should move out of their own home. He struggles to find an answer because either way they have to sacrifice something. On one hand he doesn’t want to give up his own place and let the authority wins; On the other hand he jeopardizes his family’s life if they don’t move out. A second intimidating visit soon comes. A Police man fires at his place and Arevalo just stands there â€Å"with hanging head†. In the end Juan chooses to stay in the farm with his wife and son, so they all die in a set up fire. Both external and intenal conflicts are resolved here when the authority appears to win but in fact the author sends out a message that people should not be intimidated and should stand up to corruption like Juan and his family do.

Business law discussion #2 Essay Example | Topics and Well Written Essays - 250 words

Business law discussion #2 - Essay Example After the ban was upheld by the Second Circuit Court, a CIRCUIT SPLIT arose and the ruling favored the complainant. The defendant made his appeal to the Supreme Court on grounds that the copyright clause known as FIRST-SALE DOCTRINE that authorized people residing in the United States to resell legal substances was much superior to the one that which required people to obtain the right’s of the owners before dealing with their products in the United States. The Supreme Court overturned the decision of the Second Circuit and affirmed that Kirtsaeng was duly protected by the first-sale doctrine. The case is a demonstration of the powers invested in the Supreme Court and its ability to reverse the ruling other courts deemed less superior to its judgment. The first element which is to make an offer was duly attained when Sam’s father wrote him a letter indicating his intention to transfer the Bentley to him. Sam acceptance of the offer unconditionally is a fulfilment of the second element of a contract. The third element which is the intention to enter into legal consequences is however lacking which makes the contract not a binding one and this explains why Sam will not be successful in the suit. It follows that there is no consideration in the contract which violates the fourth and final element of a binding contract. Promissory Estoppel which can be applied as a substitute to consideration may act in favor of Sam in an event that there was no legally binding contract between him and his father. This is in line with one of the elements which considers refusal of Sam’s father to transfer the Bentley to him as an act of injustice. In the case of Lucy, the body of contract law that will be applied by the court is that of voidable contract in which the contract is enforceable at the option of one of the parties involved. In this case, Lucy who was the aggrieved party had the option to either accept or

Central Engineering and Research Group (CERG) Essay

Central Engineering and Research Group (CERG) - Essay Example This approach means a move from a traditional 'control' type approach which accepts, implicitly, that defects will occur. Joseph M. Juran proposes the tools of control including the Bell system of sampling, the Shewhart control charts and inspection plans. These models could be successfully applied to CERG, but they will be replaced by modern theories of quality and cost control. The human dimension (training, education, cultural diversity management) proposed by Juran helps to motivate and inspire employees. For CERG, Juran's human approach help to create continuous motivation to achieve quality improvements, supported by appropriate education and training. Place emphasis on education will affect attitudes and motivation to achieving quality improvements. Also, Juran identified such threats as resistance to change and cultural resistance as important areas of concern. If staff are informed of changes, are encouraged to adopt a positive attitude and have personal involvement in the implementation of the change, there is a greater likelihood of their acceptance of the change (Beckford, 2002). Juran applied the Japanese philosophy on quality into Western management practices emphasizing the role of human resources and control. New quality programs should comprise a quality plan which offers a structured, disciplined approach to quality and incorporates a numbe r of tools and techniques. Particular emphasis is given to the collection and analysis of information and to employee training. It is culturally based with involvement as a core philosophy. W. Edwards Deming identifies '14 Points' which have a great impact on productivity and profitability of the company. His theory is based on process orientation which means a product quality throughout production. "It is not enough to just do your best or work hard. You must know what to work on" (Beckford, 2002). Deming creates a four step approach to quality and productivity which can be applied to CERG: plan-do-check-act. Also, he introduced Statistical Quality Control. This theory cannot be applied to CERG, bit it can be used by other departments in order to support CERG activity and increase output. Customer orientation is important for CERG, so the quality program should apply quality control principles to design/specification activities to formalize the mechanism for ensuring that customer requirements are incorporated (Arogyaswamy, Simmons, 1993). Philip Crosby marked a new era in quality management and control. His concept, "doing it right the first time" (DIRTFT), is successfully used by different industries and companies. The main principles of quality include: (1) quality is conformance to requirements; (2) the management system is prevention; (3) the performance standard is zero defects; (4) the measurement system is the cost of quality. CERG can use these principles as a core of quality philosophy. Following Crosby, quality is based on goals, measurements, and cash incentives for employees and management. It also has some aspects of quality circles. In order to make the program work, CERG should introduce: a motivational package, a prevention package (reducing management controlled defects), procedures to provide for feedback. Within CERG, low motivation results in high level of mistakes and 'defects'. For this reason, these elements of zero defects and the cost of qualit

Evaluation - Article Example Hudson is affiliated with the School of Applied Social Sciences from De Montfort University, Leicester while Singh is also associated with Applied Research Centre Health & Lifestyle Interventions of Coventry University, Coventry. The study addressed several problems facing patients with less severe chronic obstructive pulmonary disease (COPD). They specifically investigated the patients’ experience and understanding of COPD symptoms, current self-care activities, and the importance of family perceptions in managing COPD. The main subject of the study consists of patients with COPD, how they manage the condition, the challenges they encounter and the importance of having the support of family members (Apps et al., 2014). The aim of this study is to understand the experiences of individuals with less severe COPD and the challenges they face while undergoing self-care. The study population comprised of participants who had a positive diagnosis of COPD and had not been rehabilitated for pulmonary complications in the past year. They were also required not to have any neurological, cognitive or locomotor problems. The study design was cross-sectional, and the authors analyzed the data using thematic analysis, which permits identification of patterns of the data and better descriptions (Apps et al., 2014). The results of the study identified difficulty in breathing as the major symptom that the patients underwent. Also, the patients in their early stages of the condition had problems getting support from their family members since the symptoms are not visible from outside. Most patients did not know when to start engaging in the self-care procedures, and what to expect as the conditions increased in intensity (Apps et al., 2014). The results are clear since they give in detail what the patients’ experiences were, and the challenges they face while undergoing self-care. The results have also addressed the

John Galliano for Dior Crisis Essay Example | Topics and Well Written Essays - 1500 words

John Galliano for Dior Crisis - Essay Example In ten years Maison Dior had become one of the most powerful design houses in the industry with Seventh Ave depending on Dior to lead them in a mutually beneficial relationship. In 1957 the company was grossing 17 Million dollars per year, which increased to 22 million by 1958. Yves Saint Laurant, Dior’s handpicked Head Assistant became the head of Dior, but soon left after only six collections when he was called to join the French Army. He had taken up the reigns of the Dior house when he was only twenty-one years old (Blaszczyk 93). Although the design vision of the company has had to change through the transitions of designers over the years, the company pioneered a concept that secured its position in the fashion industry. According to Blaszczyk â€Å"Maison Dior’s achievement in the history of the fashion industry lies in the creation of a format for producing profits while continuing to operate the maison as a viable business for licensing† (105). What the House of Dior did was to create the first example of the power of branding and the idea of licensing was the foundation of how the profits for branding were established. Therefore, one of the most important aspects of the nature of the business is in the perceptions that the public holds for the name of Dior. This is why the crisis that occurred with John Galliano had to be handled with care and surgical precision. The House of Dior Christian Dior is currently owned by LVMH Moet Hennessy Louis Vuitton, which is owned by Bernard Arnaul. Sidney Toledano, Dior Couture’s chief executive, and the board of directors were responsible for the decision to fire Galliano during the crisis (Saltmarsh). The demographics for Dior are wide and varied, depending on what branch of the company is being discussed. However, the core of the demographics are affluent with an upper class income, varying from those who buy from the runway and are represented by the elite to those with upper middle c lass incomes that can afford higher designer level prices. The House of Dior includes Miss Dior, which is geared towards the younger woman, J’dore, which is currently the perfume that is represented by Charlize Theron, and Diorskin Forever, their skincare line represented by Natalie Portman. Dior lines include accessories, jewelry, watches, baby wear, men’s wear, and of course, women’s wear (Dior). Dior represents glamour, wealth, and couture. The house has always strived to serve the elite of the world. Christian Dior, in defiance of a restriction on fabric during World War II, created pieces in his collection that uses as much as 20 yards of fabric (Blaszczyk 93). While this suggests a sense of social defiance during a time when people were needed to band together, it also represents a belief in the luxury of life and that to live in a restricted form is to limit the possibilities. Dior’s first releases also revolutionized the look of woman. He embraced the large breasts, small waist, and long silhouette with skirts that ended at mid-calf that now still have power in women’s wear creations. His company was run with smart business moves in mind, licensing the products in order to create lines that could extend the brand. Dior is a company to be admired for the products that they produce, the luxurious lifestyle that is the cornerstone

Human Development Essay Example | Topics and Well Written Essays - 500 words

Human Development - Essay Example 3. Explain the relationship of language to memory. 4. What is theory of the mind and how does it develop? 5. How does moral development change from infancy through middle childhood? How does cognition develop from infancy through middle childhood? Cognition develops in infancy through active exploring using cognitive structures. Piaget’s cognitive theory explained that for the child to discover his surroundings has to develop his intelligence through organization and adaptation. Organization takes place when a child systematically combines existing structures with interrelated actions and ideas. Adaptation on the other hand is when a child adjusts to the demand of his surroundings employing assimilation and accommodation. A child is said to have assimilated experiences when it is interpreted in terms of cognitive structures. Existing cognitive structures are used to understand new events. While accommodation is the modification of what is learned from the earlier experiences. For example, as the child gazes an object, he tries to grasp to reach. However, as he ages, he recognizes primitive structures thus refined action is expected. The same holds true in the child’s knowledge of a dog. For his first encounter, he may give a definition of a dog to be a thing that barks. However, for successive exposures, he may look at the dog as an animal with four legs.

Intro to Philosophy Essay Example | Topics and Well Written Essays - 2000 words

Intro to Philosophy - Essay Example the individual private conversations with ourselves that we conduct ‘in our heads.† People therefore talk about "making up my mind" "changing my mind" or of being "of two minds" about some matter about which a decision is required. This fits in with the idea that the mind is a very private and personal area to which no other person has access. The etymology of the word in English shows how there is some confusion as to what ‘mind’ actually means. In Old English it was ‘gemynd’, a word used to refer to memory and intention as well as thinking (, Harper 2012), even ‘having the mind aroused’. In Greek the word ‘memona’ referred to both yearning for something and also madness. In Latin, as in Old English, the word was linked to recall and memory. In English by the 14th century ‘to mind’ meant to remember. In French however the word is ‘esprit’ or spirit, and in German ‘geist’ i.e. ghost , both referring to an intangible something. The brain is obviously a physical object, it can be measured, observed, even weighed. With modern imaging techniques it is even possible to see it in action, chemically, neurologically and electronically. The mind however is much less tangible – something we all know exists yet cannot quite explain. It is a separate entity. Our body can be totally relaxed, even asleep, but the mind can be very active. The reverse can also be true - we are running along perhaps, pushing our body to its physical limits, while at the same time the mind is simply ticking over, thinking of almost nothing. The mind can be defined as that part of conscious beings which reasons, perceives, thinks, wills and judges. The Free Dictionary defines the mind as being :- The human consciousness that originates in the brain and is manifested especially in thought, perception, emotion, will, memory and imagination. It is also described in the same dictionary as :- T he collective conscious and unconscious processes in a sentient organism that direct and influence mental and physical behavior. All cognitive being are born with amazing brains and minds, yet it is something about which humanity in general knows relatively very little. This essay will consider various views on the subject, looking at research, at opinions, secular ideas and religious texts. It is likely that man, from earliest time, has been aware that he is made up of more than physical things, more even than what he perceives through his senses - man is after all a dreamer and also capable of spiritual experiences. Probably the oldest known ideas about the mind come from Zoroaster who may have lived as long ago as 2000 B.C.E.(Parsa, undated), although estimates of his dates vary considerably. According to his biographer Zoroaster, a Persian philosopher and the founder of the Zoroastrian religion taught that :- By keeping the mind healthy and by making use of creative forces, indi viduals can find satisfaction and passion in what they do. In Buddhism the body is compared to a house and our mind to a guest staying there. According to this belief when a person dies their mind moves on into the next life or place , and the house, as houses do, stays behind to be taken care of. (Kadampa 2010). The same article also points out that, as the mind is formless, it is totally unrestricted by physical objects – which explains why it is possible to dream or to consider something without being in its

Gender stereotypes in the media Essay Example | Topics and Well Written Essays - 500 words

Gender stereotypes in the media - Essay Example When analyzing several commercials from Gender Stereotype (http://www.youtube.com/watch?v=cSIEXtDElOM), specific roles can be seen that are based on expectations of each gender. The first set of gender stereotypes presented in the first commercial show a distinct difference between the masculine and feminine roles. The male is seen working at a computer, which implies the function that men are supposed to have in society. When the woman comes into the room, she immediately begins undressing and getting into lingerie. Throughout the commercial, the woman represents the sex object that is able to entice men. Even though she walks in with a business suit, it becomes secondary to the lingerie. The masculine role is furthered by this when the sexual representation of the woman is able to interrupt the work that the man is doing in the commercial. More importantly, other men that see this on the webcam show the appeal to the sex object and the concept of men is based on the corporate and work figure. The second commercial that is used implies the same concepts about gender stereotype. The female figure is again seen as a sexual object through the lack of actions that she takes. She is seen bathing in the sun with a skimpy bikini and is unaware of what is occurring around her. The male is in the background with a fake lawn mower, which he is using to watch the woman. The gender role of the woman is based on creating a specific sexual object and figure, while the male looking at the female implies a working man that can easily be distracted or changed by watching the opposite sex. The third commercial holds to the same gender stereotypes that are incorporated in the media. There are several women that are seen throughout the commercial. Each are wearing shorter dresses, even with the work clothes that they are wearing. The size and figure of each of the women is a skinnier look, with

Theme Park Tourism Essay Domestic an International Tourism Economy, 303 Mihai Bravu Street, bl 18 A, sc B, ap 54, sector3, Bucharest, Email: [emailprotected] com, Phone 0744. 671. 291 Strutzen Gina 14 Alexandru Ioan Cuza Street, Voluntari, Ilfov, Email: [emailprotected] com, Phone: 0723. 212. 300, Romanian American Univerity, Faculty of Domestic an International Tourism Economy Theme parks are star players in the tourism industry, and play a special and important role in generating tourism demand. Theme parks are the main motivators for tourism trips to many destinations and core elements of the tourism product. Competition in the theme park market is growing also in terms of an increasing number of parks, but also relative to other uses of leisure. But in different areas, the theme park market in seems to be reaching its saturation point and the parks have to cater for visitors who are getting more and more experienced and demanding. Given these trends of growing theme park supply, environmental constraints and increasingly discriminating consumer demand, it can be concluded that theme parks, to survive in this competitive market, must optimize is, given an ever increasing number of parks and future trend of consumer behavior. Keywords: tourism, theme parks, development The theme park concept In general, theme parks can be defined as a subset of visitor attractions. Visitor attractions are described as permanent resources which are designed, controlled and managed for the enjoyment, amusement, entertainment, and education of the visiting public There are the main types of managed attractions for visitors: ancient monuments; historic buildings; parks and gardens; theme parks; wildlife attractions; museums; art galleries; industrial archeology sites; themed retail sites; amusement and leisure parks. Another definition of visitor attractions is regarded by specialists as â€Å"single units, individual sites or clearly defined small-scale geographical areas that are accessible and motivate large numbers of people to travel some distance from their home, usually in their leisure time, to visit them for a short, limited period of time†. Although this definition excludes uncontrollable and unmanageable phenomena the definition does imply that attractions are entities that are capable of being delimited and managed. The adepts of this definition consider four main types of attractions: features within the natural environment (beaches, caves, forests); man-made buildings, structures and sites that were designed for a purpose; other than attracting visitors (churches, archeological sites); man-made buildings, structures and sites that were designed to attract visitors and were purposely built to accommodate their needs, such as theme parks (theme parks, museums, waterfront developments); special events (sporting events, markets). These four types are distinguished by two aspects. Firstly, the first three types are generally permanent attractions, while the last category covers attractions that are temporary. Second, tourism is often seen as a threat to the first two types, and is generally perceived to be beneficial and an opportunity for the last two types. Managers of the first two types of attractions in general deal with problems caused by visitors, such as environmental damages and pollution, while managers of the other two types tend to aim to attract tourists, increase visitor numbers, and maximize economic input. The main features that distinguish theme parks from other kinds of visitor attractions are: †¢ a single pay-one-price admission; †¢ charge; †¢ the fact that they are mostly artificially created; †¢ the requirement of high capital investments. Theme parks attempt to create an atmosphere of another place and time, and usually emphasize one dominant theme around which architecture, landscape, rides, shows, food services, costumed personnel, retailing are 635 orchestrated. In this definition, the concept of themes is crucial to the operation of the parks, with rides, entertainment, and food all used to create several different environments. Examples of types of themes used in contemporary theme parks include history-periods, fairy tails, animals, water, marine and futurism. These themes are used to create and sustain a feeling of life involvement in a setting completely removed from daily experience. Most theme parks are isolated, self contained units. Furthermore, it needs to be noted that most theme parks are developed, targeted and managed as private sector companies, and are commercial enterprises. The world’s best known theme parks arguably are the Disney parks, such as Disneyland, Disneyworld and Euro Disney. The amusement parks, appeared previous the theme park concept, which were developed at the turn of this century and consisted of a mixture of entertainment, rides, games, and tests of skill provided at fairs, carnivals, circuses, and frequently they had an outdoor garden for drinking. Amusement parks were an important element of mass tourism in the pre-depression period. However, the World War II has strongly influenced the decline of the traditional amusement park. Many parks were forced to close down permanently, while others survived, on a reduced scale, into the 1950s or even beyond. Since the end of World War II the number and range of theme parks available to consumers has multiplied dramatically. The rise of car-ownership has increased mobility and allowed people to visit more isolated parks in their own countries that were previously inaccessible. Rising affluence has increased the amount of free time. Also, longer weekends and increased paid holidays have helped to stimulate the expansion in theme park visits. Furthermore, the growth of tourism in the past fifty years and the recognition of the economic benefits of tourism have led to the growth of purpose-built attractions, such as theme parks, specifically designed to attract tourists, and to encourage them to spend their money. Disney was the first to introduce a special and new style of parks around a number of themes or unifying ideas to sanitize the amusement park for the middle classes. The modern day techniques for reproducing landscape, buildings, and arte facts can create a reality in theme parks that has been previously the preserve of film and theatre. Through changes in transportation technology and social attitudes, downtown industrial and residential land has become redundant. For example, historic buildings are often inaccessible to the new scale of road, and historic buildings worthy of conservation are not always adaptable to new business practice. The current interest in urban space for leisure and the use of leisure as a generator for adaptation and renewal is significant. In marketing urban locations for new investment the quality of life is becoming identified with the quality of the leisure environment. During the 80’s and 90’s, theme parks began spreading around the world. While many developing nations are experiencing the entertainment of theme parks for the first time, the theme park growth slowed in the USA due to escalating costs and a lack of markets large enough to support a theme park. The development of theme parks over time has been different in every country, reflecting differences in a number of factors including: the level of economic development and the distribution of wealth; the transport system; the natural environment and built heritage; the national culture; the degree to which tourism is a matter of incoming foreign visitors rather than domestic demand. The tourism general environment of the theme parks The theme park and its total tourism environment need to be a place in which the entire array of physical features and services are provided for an assumed capacity of visitors. The tourism supply and demand market is the two sides that require close examination for theme park planning. Insight in market developments is necessary for taking a longer term perspective in theme park planning. The economic environment of theme parks The planning efforts of theme park are mostly directed towards improving the economy, because the economic impact of theme parks is generally positive including: increased direct and indirect employment, income and foreign exchange; improved transportation facilities and other infrastructure for tourism that residents also can 636 utilize; generation of government revenues for improvement of community facilities and services; the multiplier effect within the local and regional economy. Although improving the economy is an important goal, it will not be achieved unless planning for the economy is accompanied by three other goals, enhanced visitor satisfaction, protected resource assets, and integration with community social and economic life. For example, some theme parks use imported goods and services instead of taking advantage of locally available resources. Also, tourism can cause inflation of local prices of land, goods and services. The socio-cultural environment of theme parks The impact of theme park operations can bring both benefits and problems to the local society and its cultural patterns. A theme park in an area generates contact between residents and visitors. This can be problematic in areas where the traditional cultural pattern of the residents differs extremely from that of the visitors of a park. Also, when there is a substantial socioeconomic difference between the visitors and the residents this may cause a problem. For example, problems may include over crowding of facilities and transportation, over commercialization, misunderstandings and conflicts between residents and visitors because of differences in languages, customs, and value systems, and violation of local dress and behavior codes. Theme parks especially have peak attendance figures, and therefore the concentration of visitors in space and time is a major problem. On the other hand, tourism in an area may improve the living standards of people and help pay for improvements to community facilities and services if the economic benefits of tourism are well distributed. The psychically environment of theme parks Theme parks’ environmental impact is mostly negative and a cause for concern. As theme parks have been designed specifically to accommodate the modern visitor, the environmental impact of theme parks can include visual pollution like unattractive buildings and structures, and large unattractive car parks. The space occupation of parks is enormous and mostly involves destruction of parts of the natural environment. Other environmental problems are air and water pollution, noise, vehicular and pedestrian congestion, and land use incompatibility. Therefore, an essential element of theme park planning is determining the carrying capacities or use saturation levels of the area. The transportation of the theme parks Passenger transportation is a vital component of the theme park system. Theme parks have a relationship with transport systems in a number of ways: The transport networks make theme parks physically accessible to potential visitors and therefore are an important factor in determining the number of visitors a theme park is likely to attract. The e existence of major theme parks and attractions leads to the development of new public transport services to meet the demand of visitors. The transport is also important within destinations to make travel between theme parks and attractions and between attractions and services as easy as possible. The modes of transport can often be an attraction in themselves with passengers being encouraged to see using them as a type of special event. The novel methods of on-site transport are used to move visitors around the theme park in ways that will add to the enjoyment of their visit. The planning of inter modal transportation centers is needed for domestic local, as well as outside, visitor markets. The infrastructure of theme parks In addition to transportation facilities, other infrastructure elements include water supply, electric power, waste disposal, and telecommunications. These components are usually planned by the public sector. Even though private and independent decision making are valued highly by most enterprises in all tourism sectors, each will gain by better understanding the trends and plans by others. The public sector can plan for better highways, water supply, waste disposal, when private sector plans for attractions and services are known. Conversely, the private sector can plan and develop more effectively when public sector plans are known. Facilities offered by the theme parks Accommodation, hotels and other tourist facilities, provide services so that tourists can stay overnight during their travels. Other facilities necessary for tourism development include tour and travel operations, restaurants, retail 637 outlets, souvenir shops, financial facilities and services, tourist information offices, public safety facilities and services of police and fire protection. A theme park and its environment need to be planned in such a way that the entire array of physical features and services is provided for an assumed capacity of visitors. It is important in planning the services businesses to realize that they gain from clustering. Food services, lodging, and supplementary services must be grouped together and within reasonable time and distance reach for the visitor. The institutional environment The institutional elements need to be considered in planning the theme park environment. From national to local governing levels, statutory requirements may stimulate or hinder tourism development. For example, policies on infrastructure may favor one area over another. Also, the administrative laws and regulations can influence the amount and quality of tourism development in a particular area. Policies of the many departments and bureaus can greatly influence how human, physical and cultural resources are applied. The development of theme parks The theme park market worldwide has grown dramatically during the last decades. For example, in the USA (where most of the theme park trends originated), theme parks have more than 200 million paid attendees each year. This strong consumer demand has resulted in the development of many parks. These parks are not only growing rapidly in size and importance, but also are investing substantial amounts in new entertainment and facilities, and extending their services into relatively unexplored areas such as catering and accommodation.. Also, Asia is the theme park market for the new millennium. Even more, several Asian cities, like Bangkok, Singapore and Kuala Lumpur, want to become ‘tourism hubs’, and theme parks are central to these plans. Although in the Asian countries a shift from hopping centers to theme parks can be seen, the opposite can be observed as well indicating a growing role of retailing in existing theme parks. The relationship between merchandising and theme park visits clearly has potential for further growth, and the advantages of stimulating this demand are becoming increasingly recognized by theme park operators. They are racing to obtain more profits out of their rides, activities and exhibits by linking rides to merchandise and placing goods at spots where visitors are most likely to buy, and that is close to the key rides, activities and exhibits The objective is to give people a part of the park to take home and share with others. In Europe most theme parks were built in the last 25 years. First, theme parks were more a Northern Europe phenomenon, but recently, several regions and countries in Southern Europe have supported the growth of theme parks as an attractive option to increase economic input. Due to all these new parks built, the theme park market is saturating. Consequently, the competition in the European theme park market is growing. Not only in terms of the growing number of new other parks, but also due to other uses of leisure time and discretionary expenditure such as home-based entertainment systems. Managers of large theme parks are concerned about the scale of the investments required to add new exciting rides, activities and exhibits to their product. Especially, because a golden rule is that a theme park every year has to expand their park with a new attraction, to attract the required level of visitors European theme parks invest in average twenty percent of their turnover on new or better rides, activities and exhibits. Theme parks challenges The first challenge for theme parks managers is to integrate the elements in the park itself with all the elements defining the theme park environment in the theme park development plan. For example, theme parks cannot function without transportation possibilities to bring the visitor to the park, or food supply or accommodation to support the visitor’s stay. Planning a theme park requires significant public private cooperation. More and more public governments turn to the private sector for the provision of services and the production of new products However, in order for such processes to run smoothly in theme parks, greater understanding of the roles of both sectors is needed. All private sector players on the supply side of the theme park environment such as, attractions, services, transportation, etc., depend greatly on investment, planning and management policies of government. Conversely, governments depend on the private sector for many tourism activities and responsibilities. Therefore, cooperation between the public and private sector is essential. 638 Another characteristic of theme parks is that their demand is highly seasonal. For theme park planners seasonality effects mean that they need to plan the facilities in such a way that whatever season or number of visitors in the park, the visitor experiences in the park are optimal. Also, when demand for rides, activities and facilities fluctuates during the day this can cause problems for the park, such as congestion and time specific peaks at the rides, activities and facilities. For theme park managers, capacity planning and routing is therefore an important task to deal with these problems. For example, to optimize the visitor streams in the park and to minimize waiting times at the activities. Another characteristic is the fact that theme parks face high fixed costs and low variable costs. This means that the costs per visitor in the low season, when there are only few visitors in the park, are much higher than in the high season, especially if the quality of the visitor experience has to be maintained. Furthermore, each year parks require high investments to add new exciting attractions to their product to attract the required level of visitors At the demand side, theme park planners may rely on marketers to actively try and manipulate tourist demand, by price differentiation across seasons, special rates for early bookings and bundling of services and visits over time or with other tourist facilities in the region. Similar to other tourist attractions, theme parks first and foremost provide enjoyment to their customers. This implies that theme park managers face especially strong demands from customers for new and exciting innovations in their services. Special strategies need to be devised to deal with tourist variety seeking. Also typically a diverse number of services within a park is required to promote repeat visits and to cater for different members of visitors groups as seniors and children) and for different segments in the tourist population at large. This has important implications for theme park planning in terms of location and type of activities that should be introduced and supported. Detailed consumer information often is essential to meet these consumers’ requirements. The costumers requirements place special demands on theme park planners in terms of: meeting environmental standards imposed through (inter)national regulations and local communities, by increasing demands in terms of landscaping and design, and financial responsibilities in terms of managing large areas of land which need to be bought, leased or rented depending on the organization’s financial management strategy. Another challenge facing theme park planner is that planning a park requires special skills in terms of combining creative and commercial abilities. Theme park design is crucial in determining the success of a park. In terms of design, several different levels can be distinguished. First, rides, activities and exhibits have to be designed attractively and effectively both in terms of initial appeal and usage. Second, landscaping and urban designs are required to integrate the different single facilities into a whole based on the selected theme for the park. And finally, activities and services need to be arranged that can support and increase consumer experiences of the physical elements in the park. There also are some more general features of the theme park product that are shared with other services and that are a challenge to theme park planning. Meeting consumer demand must be done however without compromising environmental and socio-cultural objectives. Because the theme product is consumed and produced at the same time, the service must be right the first time. Therefore, adequate theme park planning is highly critical for optimizing the delivery of the theme park product to the consumer. The final challenges facing theme park planners are created by the theme park market. There is a growing competition in the theme park market, with an ever increasing number of parks and many parks expanding their activities. Even more so, the tourist demand market is facing demographic changes in the form of agreeing population, economic changes that lead to tighter family time budgets because of an increasing number of double earner households, and the introduction of new technologies such as multimedia entertainment that compete directly with the traditional theme park market. Knowledge of potential market origins, and interests, habits and other travel characteristics of the population is a necessary but not sufficient condition to plan the several components of the supply side. It is important for the parks to know how consumers think, and what makes them visit or not visit attractions, and when they want to visit a park. Also, for theme park planners, an estimate of peak visitor volume is essential to the planning of every feature of the theme park, parking, attractions, exhibits, toilet facilities, tour guidance, food services and souvenir sales. 639 It can be concluded that the challenges theme park planners face ask for planning methods that can integrate the different components in the planning processes within and across various levels of planning.

Application Of EM Waves In Satellite Communication Computer Science Essay

Application Of EM Waves In Satellite Communication Computer Science Essay This paper deals with the historical development of satellite communication systems. Then the basic elements of satellite communication system along with their features are discussed. Then the working of a satellite communication system and the use of EM waves in this system is discussed and then finally the applications, advantages and limitations of satellite communication system are discussed. Introduction Electromagnetic wave is a wave of electric and magnetic field components which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. Generally, EM radiation (the designation radiation excludes static electric and magnetic and near fields) is classified by wavelength into radio, microwave, infrared, the visible region we perceive as light, ultraviolet, X-rays and gamma rays..The behaviour of EM radiation depends on its wavelength. Higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Spectroscopy can detect a much wider region of the EM spectrum than the visible range of 400  nm to 700  nm. Electromagnetic waves as a general phenomenon were predicted by the classical laws of electricity and magnetism, known as Maxwells equations. If you inspect Maxwells equations without sources (charges or currents) then you will find that, along with the possibility of nothing happening, the theory will also admit nontrivial solutions of changing electric and magnetic fields. Any electric charge which accelerates, or any changing magnetic field, produces electromagnetic radiation. Electromagnetic information about the charge travels at the speed of light. Accurate treatment thus incorporates a concept known as retarded time. At most wavelengths, however, the information carried by electromagnetic radiation is not directly detected by human senses. Natural sources produce EM radiation across the spectrum, and our technology can also manipulate a broad range of wavelengths. Fig. 1 electromagnetic spectrum Satellite Communication A satellite is a physical object that orbits or revolves around some celestial body. In general satellite is an artificial satellite stationed in space for the purposes of communication, military, surveillance, etc. A satellite communications (sometimes abbreviated to Comsat) is an artificial satellite stationed in space for the purposes of telecommunications using microwave frequencies. Most communications satellites use geosynchronous orbits or near geostationary orbits, although some recent systems use low Earth-orbiting satellites. Communications satellites provide a technology that is complementary to that of fibre optic submarine communication cables. Unlike fibre optic communication, satellite communication has a propagation delay (also called a path delay) of at least 270 milliseconds, which is the time it takes the radio signal to travel 35,800 km from earth to a satellite and then back to earth. Satellite Internet connections average a 600-800 millisecond delay, about ten times than that of a terrestrial Internet link. This delay is a challenge to deployment of Virtual private networks over satellite internet connections. HISTORY OF SATELLITE COMMUNICATION The concept of satellite communications was first proposed by Arthur C. Clarke, based on Herman PotoÄ niks pseudonymous work from 1929. In 1945 Clarke published an article titled Extra-terrestrial Relays in the magazine Wireless World. The article described the fundamentals behind the deployment artificial satellites in geostationary orbits for the purpose of relaying radio signal. Thus Arthur C. Clarke is often quoted as the inventor of the communications satellite. The first artificial satellite was the SOVIET SPUTNLK-1 launched on October 4, 1957, and aquipped with an onboard transmitter that worked on two frequencies i.e. 20.005 and 40.002 MHz The first American satellite to relay communications was project SCORE in 1958 which used tape recorder to store and forward voice messages. Telstar was the first active, direct relay communications satellite belonging to AT T. USE OF EM WAVES IN SATELLITE COMMUNICATION The fastest growing and most recent field of communication involves the use of various satellite relays. Let us discuss the space wave communication. In this mode of propagation, electromagnetic waves from the transmitting antenna reach the receiving antenna either directly or after reflections from ground in the earths troposphere region. Troposphere is that portion of the earth which extends up to 16 km from the earth surface. It means in the former, wave reaches directly from the transmitting antenna to receiving antenna and in later, the wave reaches the receiving antenna after reflection from the ground., where the phase change of 180 degree is also introduced due to reflection at the ground, in the ground reflected wave. Although both the waves leave the transmitting antenna at the same time with the same phase but may reach the receiving antenna either in the phase or out of the phase, because the two wave travel different path lengths. The strength of the resultant waves, thu s, at the receiving point may be stronger or weaker than the direct path alone depending upon whether the two waves are adding or opposing in phase. At receiving point the signal strength is the vector addition of direct and indirect waves. Space wave propagation is also called as tropospheric propagation because space wave propagates through troposphere. Space wave propagation is mainly in VHF, and higher frequencies because at such frequencies sky wave and ground wave propagation both fail. Beyond 30 MHz sky wave fails as the wavelength becomes too shorts to be reflected from ionosphere and ground waves are propagating close to the antenna only, as attenuation is very high. Therefore just after few hundred feet ground wave also die due to attenuation and wave tilt. Space wave propagation is also called as the line of sight propagation because at VHF, UHF and microwave frequencies, this mode of propagation is limited to the line of sight distance and is also limited by the curvatur e of earth. Although in actual particle space wave propagates even slightly beyond the line of sight distance due to the refraction in the atmosphere of the earth. In line of sight distance transmitting antenna and receiving antenna can usually see each other. In fact, the line of sight distance i.e. range of communication can also be increased by increasing the heights of transmitting and receiving antennas. The curvature of earth and the height of the transmitting and receiving antennas determines maximum range of communication through direct waves. In fact, the line of sight distance has now been extended by what is known as Space Communication or specially Satellite communication which has facilitated trans-oceanic propagation of microwaves with the potentiality of large bandwidth. By space communication we mean the radio traffic between a ground station and satellite or space probe, between satellites or space probes and also between the ground station itself via man made communication satellites or natural space body( e.g. the sun, the moon, the venus etc. ). Earlier it was not possible to propagate beyond the radio horizon and hence it revolutionized the field of communication engineering and it is possible to show that three geosynchronous satellites can establish communication over entire world. Role of electromagnetic waves can be seen by studying the different bands available for satellite communication Selection of the band The selection of the band is not something that individual service providers decide, but is rather chosen by large satellite operators based on different factors. These are explained below: C-band is still the most widely available worldwide. Ku-band is becoming more available recently in regions which were less covered in the past (South America, Asia, Africa). C-band is more prone to interference from other transmission services that share the same frequencies (adjacent satellites or terrestrial transmissions) than the higher bands. While the C-band technology is cheaper in itself, it requires larger dishes (1 to 3 m) than Ku- and Ka-band (0.6 to 1.8 m) and therefore imposes relatively higher (installation) costs on the end-user. Ku- and especially Ka-band make better use of satellite capacity. Higher frequency bands (Ku- and especially Ka-) suffer significantly more from signal deterioration caused by rainfall: to ensure availability in bad weather conditions, the signal has to be much stronger. Note that 0.1% of unavailability means in fact that the service will be interrupted for almost 9 hours over a 1-year period. 1% unavailability represents 90 hours or almost 4 full days. Bands of Interest C-band is the oldest allocation and operates in the frequency range around 6 GHz for transmission (uplink) and between 3.7 and 4.2 GHz for reception (downlink). Ku-band is the most common transmission format in Europe for satellite TV and uses around 14 GHz for uplink and between 10.9 and 12.75 GHz for downlink. Ka-band uses around 30 GHz up- and between 18 and 20 GHz downlink frequency. C-band and Ku-band are becoming congested by an increasing amount of users, so satellite service operators are more and more turning to the use of Ka-band. Using C-band and K-band C Band is a name given to certain portions of the electromagnetic spectrum, as well as a range of wavelengths of light, used for communications. The IEEE C band and its variations, in particular, are microwave ranges used for certain satellite television broadcasts, and by some Wi-Fi devices, cordless phones, and weather radars. Typical antenna sizes on C-band capable systems ranges from 7.5 to 12 feet (2.5 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used. Slight variations of C band frequencies are approved for use in various parts of the world. TABLE I C Band Variants Around The World Band Transmit Frequency (GHz) Receive Frequency (GHz) Extended C Band 5.850-6.425 3.625-4.200 Super Extended C Band 5.850-6.725 3.400-4.200 INSAT C Band 6.725-7.025 4.500-4.800 Palapa C Band 6.425-6.725 6.425-6.725 Russian C Band 5.975-6.475 3.650-4.150 LMI C Band 5.725-6.025 3.700-4.000 K band is defined as a frequency band between 20 and 40 GHz (7.5-15 mm). The IEEE K band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging between 18 and 27 GHz. K band between 18 and 26.5 GHz is absorbed easily by water vapour (water resonance peak at 22.24 GHz, 1.35 cm). The IEEE K band is conventionally divided into three sub-bands:  · Ka band: K-above band, 26.5-40 GHz, mainly used for radar and experimental communications.  · K-band 18-27 GHz  · Ku band: K-under band, 12-18 GHz, mainly used for satellite communications, terrestrial microwave communications, and radar, especially police traffic-speed detectors. MAIN COMPONENTS OF A SATELLITE COMMUNICATION SYSTEM Satellite communications are comprised of two basic elements The satellite The ground station The Satellite The satellite is also known as the space segment. It is composed of the following separate units; the satellite and telemetry controls and the transponder. The transponder comprised of the receiving antenna to catch-up signals from the ground station, a broad band receiver, an input multiplexer and a frequency converter that is used to reroute the received signals through a high powered amplifier for downlink. The main function of satellite is to reflect signals. In case of a telecom satellite, the primary role is to pick up signals from a ground station, which is located, a considerable away from the first. This relay action can be two way, as in the case of a long distance phone call. Another use of satellite is the television broadcasts. Number of programs are first up-linked and then down-linked over wide region. The customer having appropriate devices can receive and watch the programs. One of the modern uses of satellite is getting information along with image (commonly known as space/satellite image) of any desired location on earth. Fig. 2 diagram showing satellite and ground station The Ground Station This is called the earth segment. Earth station is the common name for every installation located on the Earths surface and intended for communication (transmission and/or reception) with one or more satellites. A base band processor, an up-converter, high Powered amplifier and a parabolic dish antenna is involved to transmit the terrestrial data to an orbiting satellite. In the case of downlink, the ultimate reverse operation is being down and up-linked signals are recaptured through parabolic antenna. WORKING OF A SATELLITE Satellite is mainly working on the basis of Electromagnetic waves. In our daily life EM waves are useful for Radio, Internet, T.V etc. For all these electronic equipments are working on the basis of EM waves. Firstly a satellite is keep in the orbit. Then it rotates along the orbit. From the source station it receives signals and spread them to all the electronic equipments. Satellites easily transfer news with in fraction of seconds it means in microseconds. In order send signals the smallest frequency waves are required. At the station the producers send the microwaves to satellite, because microwaves are waves having short frequency when compare to the other waves (Microwaves are electromagnetic waves with frequency from 30MHz to 1GB) ,they can easily penetrate throw the ionosphere, and reaches to satellite. Satellites provide links in two ways. Firstly a satellite provide point to point communication link between one ground station and the other. One ground station transmit signal to the other satellite and next ground station receives them from the satellite. Secondly, satellite receives signals from one ground station and transmits to them to the number of ground receivers. It is illustrated in figure 2. Most satellite use frequency bandwidth through from 5.92 to 6.4GHz from transmission of data from earth to the satellite and a frequency bandwidth from 3.7 to 4.1GHz for transmission from satellite to the earth. A satellite can provide service to a certain part of the earth if it is in sight. This can be done only if the satellite remains stationary with respect to the earth. LOW EARTH ORBITING COMMUNICATION SATELLITE In 1960, the simplest communications satellite ever conceived was launched. It was called Echo, because it consisted only of a large (100 feet in diameter) aluminized plastic balloon. Radio and TV signals transmitted to the satellite would be reflected back to earth and could be received by any station within view of the satellite. Fig. 3 diagram showing Echo satellite Unfortunately, in its low earth orbit, the Echo satellite circled the earth every ninety minutes. This meant that although virtually everybody on earth would eventually see it, no one person, ever saw it for more than 10 minutes or so out of every 90 minute orbit. Telstar satellite Telstar is the name of various communications satellites; including the first ever such satellite able to relay television signals. The first two Telstar satellites were Telstar 1, launched July 10, 1962 and operational until February 21, 1963, and Telstar 2, launched May 7, 1963 and operational until May 16, 1965. They were experimental, and nearly identical. Telstar 1 relayed the first television pictures, telephone calls and fax images through space and provided the first live transatlantic television feed. Telstars orbit was such that it could see Europe and the US simultaneously during one part of its orbit. During another part of its orbit it could see both Japan and the U.S. As a result, it provided real- time communications between the United States and those two areas for a few minutes out of every hour. Some of the main advantages of low and medium earth orbit include: (a) the possibility of using hand-held receiver terminals because satellites are closer to the Earth and can therefore provide stronger signals at the receiver and ground stations need to transmit at lower power; (b) the possibility of reusing the frequencies more often than is possible with geostationary orbit because the geographical area covered by low earth orbit satellites is much smaller; (c) the possibility of reduction in transmission delay. Fig. 4 diagram showing Telstar satellite Geostationary Communications Satellites In 1963, the necessary rocket booster power was available for the first time and the first geostationary satellite, Syncom 2, was launched by NASA. For those who could see it, the satellite was available 100% of the time, 24 hours a day. The satellite could view approximately 42% of the earth. For those outside of that viewing area, of course, the satellite was NEVER available. Fig. 5 diagram showing Geostationary satellite INDIAS FIRST COMMUNICATION SATELLITE APPLE Apple stands for Airline Passenger Payload Experiment. It got the name as it was carried as a Passenger by the European space agency. Apple the first Indian three-axis stabilized geo-stationary experimental communication satellite, weighing 673kg was successfully launched on June 19, 1981 from Kourou, French Guyana, by the Ariane Launch Vehicle of European Space Agency on its third developmental flight. After 17 minutes 25 seconds the craft was successfully placed in the transfer orbit. The space craft sub-systems were functioning normally. Test commands have been issued from SHAR to the APPLE space craft successfully. Fig. 6 diagram showing APPLE satellite Launch Date: 19.06.1981 Launch Vehicle: Ariane-1(V-3) Type of Satellite: Geo-Stationary Satellite Mission: Experimental geostationary communication Weight: 670 kg Communication: VHF and C-band Stabilization: Three axis stabilized (biased momentum) with Momentum Wheels, Torques Hydrazine based Reaction control system Mission life: Two years APPLICATIONS OF SATELLITE COMMUNICATION The breakthrough provided by satellites in telecommunications resulted in a major research and development effort in all the related technologies. Most of the early work concentrated on international point to point telecommunications applications. Later, the application of satellite communication was extended to the direct satellite broadcasts (1970s), mobile communications (1980s), and personal communications (1990s). In general, satellites are serving the mobile and broadcast. Radio and Television Broadcasting Satellites have been used since 1960 to transmit broadcast television signals between the network hubs of television companies and their network members. Sometime, a whole set of programs is transmitted at once and recorded at the affiliate, and then broadcast to the local populace according to the appropriate time. In the 1970s it became possible for private individuals to download the same signals that the network and cable companies were transmitting, using C-band reception dishes. This free viewing of the corporate contents by individuals let to scrambling and subsequent resale of the descrambling codes to individual customers, which started the direct-to-home industry. The direct-to-home industry has gathered even greater response since the introduction of digital direct broadcast service. . Business Radio And TV Digital television has made it possible to distribute information within organizations and companies that are geographically dispersed, or to deliver distance education. Similarly, digital radio allows for the delivery of radio services to relatively small closed user groups. Thin Route or Trunk Telephony Telecom operators have been using satellite communications for many years to carry long-distance telephone communications, especially intercontinental, to complement or to bypass submarine cables. To the end-user this is transparent: the phone calls are routed automatically via the available capacity at any given moment. Mobile satellite telephony Mobile telephony allows the user to make telephone calls and to transmit and receive data from wherever he/she is located. Digital cellular mobile telephony such as GSM has become a worldwide standard for mobile communications, but its services lack coverage over areas that are sparsely populated or uninhabited (mountains, jungle, sea), because it is not economically viable or practical for the network operators to build antennas there. Satellite telephony seems to be able to provide a possible solution to the problem of providing voice and data communications services to these other locations Marine Communications In the marine community, satellite communication systems such as Immarsat provide good communication links to ships at sea. These links use a VSAT type device to connect to geosynchronous satellites, which in turn links the ship to a land based point having respective telecommunications system. Global Positioning Services Another VSAT oriented service, in which a small apparatus containing the ability to determine navigational coordinates by calculating a triangulating or the signals from multiple geosynchronous. Military Satellite System For military communications Army, Air force and Navy use both fixed and mobile satellite systems. In addition to the normal communications, military communications are also required for tactical communications from remote and inhospitable locations. The special requirements of military communication terminals are high reliability, ruggedness, compact, operations under hostile environment, immunity to jamming, ease of portability and transportation, etc. Examples of military satellite communications systems are: DSCS (US AF) SKYNET (UK) NATO (NATO) FLTSATCOM (US NAVY) MILSTAR Because of the special frequency band used in Military satellite system and other special requirements, Military satellite Systems are always much costlier and it takes longer time to design and develop compared to commercial satellite communications systems. Realizing that not all communications are strategic in nature, there is a trend now to use commercial communications system as far as possible. US Department of Defence is one of the major users of commercial Iridium satellite system with their own gateway. Broadband Satellite System Broadband satellite service is an emerging service which has caught the fancy of many for meeting the demand of worldwide fibre like access to telecommunications services such as computer networking, broadband Internet access, interactive multimedia and high quality voice. These systems use advanced satellite technology at Ka band or Ku band frequencies to achieve the high bandwidth requirements. Examples of proposed Broadband Satellite systems are: Teledesic, SkyBridge, Spaceway LIMITATIONS OF SATELLITE COMMUNICATION Latency (Propagation Delay) Due to the high altitudes of satellite orbits, the time required for a transmission to navigate a satellite link (2/10ths of a second from earth station to earth station) could cause a variety of problems on a high speed terrestrial network that is waiting for the packets. Poor Bandwidth Due to radio spectrum limitations, there is a fixed amount of bandwidth allocable to satellite transmission. Noise The strength of a radio signals strength is in proportion to the square of the distance travelled. Due to the distance between ground station and satellite, the signal ultimately gets very weak. This problem can be solved by modulation of carrier wave. Conclusion The outer space has always fascinated people on the earth and communication through space evolved as an offshoot of ideas for space travel. The earliest idea of using artificial satellites for communications is found in a science fiction Brick Moon by Edward Evert Hale, published in 1869-70. While the early fictional accounts of satellite and space communications bear little resemblance to the technology as it exists today, they are of significance since they represent the origins of the idea from which the technology eventually evolved. The satellite communication through the EM waves has many applications for the smooth functioning of life and it made the communication with each other very simple. In the area of satellite communications, the technology has been responsive to the imaginative dreams. Hence it is also expected that technological innovations will lead the evolution of satellite communications towards the visions of today.

joseph king :: essays research papers

Joseph King was born 25th July 1886 at Bulli NSW Australia. His father, Edward, was born in Surrey England in 1842 and migrated to Australia with his family during the gold rush to Hill End NSW in 1861. His mother, Jane, was born in 1852 at Portland Head on the Hawkesbury River in NSW. His father had a previous marraige to Rebecca Maris who bore him four children and died having a fifth. Two of those children subsequently died on the goldfields. He was one of seven born by Jane and was the second youngest. In 1880 the family moved to Bulli where Edward became a coal miner. He died in 1889 of \'black lung\' leaving Jane with nine children, Joseph was 21/2 y.o. Joseph and his brothers all worked in the mines up until the Great War of 1914-18. Joseph enlisted at Goulburn NSW on 24th February 1916. He was 271/2 years old, 5ft 6in high and weighed 130lbs. He had fair hair, fair complexion and blue eyes. He was accepted as part of the 4th Reinforcements 55th Battalion on the 8th March 1916. Originally assigned to \'D\' company he was transferred to \'B\' company before leaving Australia. The 55th Battalion was raised in Egypt on 12th February 1916 as part of the \'doubling\' of the AIF. Half of its recruits were Gallipoli veterans from the 3rd Battalion, and the other half were fresh reinforcements from Australia. Most of the men from the 4th Reinforcements came from the Monaro area. For Joseph to walk across the mountains from the coast to Goulburn to enlist at 27 years of age and so late in the war, he must have been motivated by patriotic fervour brought on by reports of the Gallipoli campaign which would have been sweeping Australia by then. (Gallipoli landing was 25th April 1915 and evacuation was 20th December 1915). After 6 months training in Australia 4/55th Battalion embarked from Sydney 4th September 1916 and disembarked Plymouth England 29th October 1916. More training in England followed until they embarked from Folkstone England 14th December 1916 and disembarked at Boulogne France 15th December 1916 and were marched into the base depot at Etaples. Here all the drafts - though they had already been passed in England as fully trained - were subjected to further tests laid down by GHQ which involved at least 10 days additional training by English instructional officers. Joseph was marched out to his unit and taken on strength in the field on Christmas eve 24th December 1916.

The Telephone :: Free Essay Writer

The Telephone A number of inventors believed that voice and sounds might be carried over wires and all worked toward it but there was only one that ended up figuring it out. The first to achieve this everlasting success was a Scottish-born American inventor , Alexander Graham Bell, a teacher for the deaf in Boston, Massachusetts. Bell was born on March 3, 1847, in Edinburgh, Scotland, and was taught at the universities of Edinburgh and London. He moved to Canada in 1870 and to the United States in 1871. In the United States he began teaching deaf-mutes, publicizing the system called visible speech . His father, who was a Scottish teacher, developed visible speech, Alexander Melville Bell. Visible speech shows how the lips, tongue, and throat are used in the making of sound out of the mouth. In 1872 Bell opened a school to train teachers of the deaf in Boston. The school soon became part of Boston University, where Bell was assigned the professor of vocal physiology. He became a U.S. citizen in 1882. Since Bell was 18 years old, he was trying to come up with the idea of transmitting speech. In 1874, he figured out the basic parts of the telephone. The experiments with his assistant Thomas Watson finally was successful on March 10, 1876, when the first complete sentence was transmitted: â€Å"Watson, come here; I want you.† There were lots of different demonstrations showing the invention, but the most popular one was the one at the 1876 Centennial Exposition in Philadelphia, Pennsylvania. This was when the telephone was introduced to the world and led to the organization of the Bell Telephone Company in 1877. When the Bell Telephone Company finally got going the company strongly dheld its patents so it will exclude others from the telephone business. After these patents expired in 1893 and 1894, independent telephone companies started up in many cities and most small towns.

The Church and Gay, Lesbian and Bisexual Issues :: Argumentative Persuasive Essay Examples

Free Essays - The Church and Gays, Lesbians The Catholic Church loves LGBT people with a profound love, just like it loves all of its other children. Various organizations within the church have as their main purpose the delivery of the Gospel to LGBT's. All of us are sacred creations of God, and therefore deserve respect on the basis of our human nature. This essay treats an outreach effort of the church in this area. In the rite of baptism, the liturgy joyfully proclaims, "you are God's work of art, created in Christ Jesus." Today, lesbian and gay Catholics are reminding the Church that they, too, have been baptized. Many are beginning to reclaim their membership in the body of Christ and the Church. As baptized persons, lesbian and gay Catholics share the rights of all the baptized: "to receive the sacraments, to be nourished with the Word of God and to be sustained by the other spiritual helps of the Church" (Catechism) Increasing numbers of lesbian and gay people are taking another look at the Catholic Church, which they thought had previously rejected them totally and definitively. Many are discovering in the Church a new spirit of understanding: "[I]t seems appropriate to understand sexual orientation (heterosexual or homosexual) as a deep-seated dimension of one's personality and to recognize its relative stability in a person. Generally, homosexual orientation is experienced as a given, not as something freely chosen. By itself, therefore, a homosexual orientation cannot be considered sinful, for morality presumes the freedom to choose. The teachings of the Church make it clear that the fundamental human rights of homosexual persons must be defended and that all of us must strive to eliminate any forms of injustice, oppression, or violence against them"(Pastoral). "It is not sufficient only to avoid unjust discrimination. Homosexual persons 'must be accepted with respect, compassion and sensitivity'"(Catechism par.2358, Always 6,9) The U.S. bishops expressed their welcome of lesbian and gay people in 1976, and repeated it in 1991: "Homosexual [persons], like everyone else, should not suffer from prejudice against their basic human rights. They have a right to respect, friendship, and justice. They should have an active role in the Christian community.(To Live) Today, many dioceses and parishes are inviting lesbian and gay Catholics to assume active roles in the Christian community. Ministries of outreach and pastoral services welcome lesbian and gay Catholics to share their gifts with the entire Church.

Defined Marketing

Many people incorrectly believe that marketing and advertising are the same. From an organizational point of view, marketing is the process of determining the needs and wants of consumers, as well as profitable providing consumers with goods and services they are looking for, or even overcome their expectations. Marketing activity needs to ensure that the products are provided to users in places where they want them, and at the price they are willing to pay, and that information is provided directly by users. This paper will provide several definitions of marketing and explain its importance in organizational success, supported by examples from the business world. Dr. Philip Kotler defines marketing as â€Å"the science and art of exploring, creating, and delivering value to satisfy the needs of a target market at a profit. Marketing identifies unfulfilled needs and desires. It defines, measures and quantifies the size of the identified market and the profit potential. It pinpoints which segments the company is capable of serving best and it designs and promotes the appropriate products and services (Kotler, 2012)†. According to Kotler, marketing is also a social and managerial process by which individuals and groups – through creating, offering and exchanging products of value with others, are getting what they need or what they want. Peter Drucker wrote the following: â€Å"Because the purpose of business is to create and keep a customer, the business enterprise has two, and only two, basic functions: marketing and innovation. Marketing and innovation produce results; all the rest are costs. Marketing is the distinguishing, unique function of the business (Drucker, 1973). Marketing plays a central role in achieving organizational success, because it talks about creating and retaining customers. For this reason, companies are focused on marketing, recognizing the importance of building relationships with customers by providing customer satisfaction, and the importance of attracting new customers by creating additional value. Gronroos, in his definition of marketing, emphasizes the importance of building relationships, in which he said that the goal of marketing is to stablish, develop and commercialize long-term relationships with our customers, so that the objectives of stakeholders are met (1999, Gronroos). Since the majority of the market is characterized by fierce competition, this statement indicates a need to monitor and understand the competition, as rivals are those that will turn customers when their needs are not being met. In the exciting world of business, successes and failures are common. Marketing is the essence of all the changes, and it is often the decisive factor in their outcome. This is because the focus is on the customers and their changing needs. Successful organizations are those that are able, not only to get new customers, but also to retain them, by always meeting their changing needs. The company's activities are both reflected and shaped the world in which we live. Almost every year there is a new product or service that fully occupies the attention of the market and makes a great success. Companies are responding to customer needs by proposing that value by providing number of benefits that are offered to customers to meet their needs. Value of the intangible becomes physical, the proposal that may be a combination of products, services, information, and experiences. Brand represents an offer from a known source. Name brand, like McDonald's raises many associations with people: hamburgers, fun, children, fast food, coziness, and so on. These associations make up the brand image. All the companies are struggling to build a powerful brand – to be strong, popular and unique. The essence of the brand is to emotionally connect with consumers and achieve lasting impressions. It should be summed up in a few words, a simple statement that defines the quality, character and uniqueness of the brand. For example, Hallmark sums up the essence of their brand through two words â€Å"enriching lives,† and those two words are the basis for everything in Hallmark, the greeting card design, product development through customer service, merchandising, in-store communications and advertising, and to create a positive working environment for their employment. Hallmark brand essence permeates every aspect of the company and its operations. If we ask marketing and advertising experts around the world, what is the secret of Apple’s success, the answer would always be the same: It's all about the brand. Apple's success owes little to innovative products such as the iPhone, iPad or iPod. The key to their success is the brand that they created. It is no coincidence that during the '80s and '90s, executive marketing director and CEO of Apple, was the former CEO of Pepsi, John Sculley. It is he who, with the vision and energy of Steve Jobs, is responsible for the tectonic shift in the perception of marketing personal computers, which was created using the marketing strategy that was used in the war with Coca-Cola. That strategy has turned Apple into the largest computer company today. â€Å"People talk about technology, but Apple was a marketing company,† Sculley told the Guardian newspaper in 1997. â€Å"It was the marketing company of the decade (Kahney, 2002)†. The company that is aware of the barely noticeable changes that are taking place every day in the market has an advantage over a company that ignores those changes. The ability to anticipate future needs and to respond appropriately is a challenge that is always present in the marketing strategy of any organization. Despite the long tradition, there are no guarantees that all organizations will adopt marketing orientation. Companies that are marketing oriented, primarily focus on customer needs. The changes are seen as a common occurrence, and the ability to adapt is seen as a necessity for survival. The aim of marketing is a long-term customer satisfaction, rather than short-term deceptions and tricks.

Analysis of Acid by Titration with Sodium Hydroxide

Stephanie Thao Chemistry 1151 Laboratory Analysis of acid by titration with sodium hydroxide Ms. Hoang November 2012 Introduction: The purpose of this experiment is to demonstrate an example of how to determine the unknown molarity of hydrochloric acid by titration with a base (sodium hydroxide). Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (wekipedia). The first step will be measuring and combining water and acid (Hydrochloric acid).An indicator anthocyanin will be added to the solution to change the color to pink. Anthocyanin is a water-soluble vacuolar pigment that may appear red, purple, or blue depending on the pH (Wikipedia). This pink color acts as a pH meter and will show a change in color to represent a change in the pH. As the base (sodium hydroxide) is added, the solution will then change color (this is referred to as the â€Å"stoichiometric end point†). This c olor change represents the increase of pH, as well as showing that the moles of the acid in the solution are equal to the moles of the base (Survey of Chemistry lab manual).Using a dilution equation of M1xV1=M2xV2, the concentration of the hydrochloric acid can be calculated. M1=NaOH(molarity), V1=NaOH(volume), M2=HCl(molarity), V2=HCl(volume). Procedure: Instructions for laboratory were found on page 91 of Survey of Chemistry lab manual. All calculations were rounded off by 2 decimal places for accuracy. Preparation of the indicator required a combination of 50 grams of cabbage with 50ml of ethanol and 20mL of DI water to extract the anthocyanin indicator. This procedure was completed by the instructor and the anthocyanin indicator (â€Å"cabbage extract†) was provided.Then 10mL of hydrochloric acid and 20mL in of deionized water were measured in a graduated cylinder and combined into an Erlenmeyer flask. Pipette 5 to 10 drops of anthocyanin indicator was added to the soluti on in Erlenmeyer flask until the solution change to a pink color. Then the solution was titrated with sodium hydroxide until the solution changed color from pink to blue. The titration of the acid was repeated in three trials. All data and calculations were recorded. Data Tables: Solution Table Acid Bottle Code: #9| Trial # 1| Trial #2| Trial #3| Final buret reading acid (mL)| 9. 1| 9. 2| 10. 10| Volume of acid used (mL)| 9. | 9. 2| 10. 10| Final buret reading NaOH (mL)| 26. 30| 44. 70| 45. 50| Initial buret reading NaOH (mL)| 7. 91| 26. 30| 26. 50| Volume of NaOH (mL)| 18. 39| 18. 40| 19. 00| Concentration of NaOH (M)| 0. 1| 0. 1| 0. 1| Molarity of the acid (HCl)| 0. 202M| 0. 199M| 0. 182M| Ratio of volume of NaOH used (mL) to volume of acid used (mL)| | | | Calculations: As previously stated in introduction, formula M1xV1=M2xV2 found on page 93 of Survey of Chemistry laboratory manual was used to calculate the concentration of hydrochloric acid (HCl). Trial 1 M1 = 0. 1 (NaOH) V1 = 18. 39mL (NaOH) M2=Unknown (HCl) V2=9. mL (HCl) 0. 1 x 18. 39 = M2 x 9. 1 1. 839/9. 1 = M2 M2 = 0. 202M Trial 2 M1 = 0. 1 (NaOH) V1 = 18. 40mL (NaOH) M2=Unknown (HCl) V2=9. 2mL (HCl) 0. 1 x 18. 40 = M2 x 9. 2 1. 839/9. 2 = M2 M2 = 0. 199M Trial 3 M1 = 0. 1 (NaOH) V1 = 19. 00mL (NaOH) M2=Unknown (HCl) V2=10. 10mL (HCl) 0. 1 x 18. 39=M2 x 10. 10 1. 839/10. 10 = M2 M2 = 0. 182M Average of acid 0. 202 + 0. 199 + 0. 182/3 = 0. 194M = M average Discussion and conclusion: This lab was successful in the proper color change needed to represent an end point when acid (hydrochloric acid) and indicator anthocyanin is titrated with a base (sodium hydroxide).As stated in the lab manual anthocyanin will go from a color of pink to blue, a pH of seven to eight, where the blue is an indication that acid has been neutralized by the base (Survey of Chemistry lab manual). During this experiment after adding enough sodium hydroxide to the indicator solution; the solution changed color to blue, an indica tion of the stoichiometric end point. All three trials showed the proper color change. This proved that the color change indicated that the pH level had changed in solution and the amount of base added is chemically equivalent to the acid in the flask.The formula M1xV1=M2xV2 was used to calculate the unknown concentration of hydrochloric acid. The results from the trials showed that the concentration of hydrochloric acid was 0. 2M. The concentration of the two acids should be relatively close in order to cancel each other out. It was complicated to compare the two concentrations since the given molarity of sodium hydroxide is in the one decimal place holder, whereas the calculated concentration for hydrochloric acid is in a two decimal place. From the lab it can be concluded that pH indicators can be an imprecise method to calculate the concentration of an unknown concentration.Critical Thinking Questions 1. Trial 1 M1 = 0. 1 (NaOH) V1 = 18. 39mL (NaOH) M2=Unknown (HCl) V2=9. 1mL (H Cl) 0. 1 x 18. 39 = M2 x 9. 1 1. 839/9. 1 = M2 M2 = 0. 202M Trial 2 M1 = 0. 1 (NaOH) V1 = 18. 40mL (NaOH) M2=Unknown (HCl) V2=9. 2mL (HCl) 0. 1 x 18. 40 = M2 x 9. 2 1. 839/9. 2 = M2 M2 = 0. 199M Trial 3 M1 = 0. 1 (NaOH) V1 = 19. 00mL (NaOH) M2=Unknown (HCl) V2=10. 10mL (HCl) 0. 1 x 18. 39=M2 x 9. 1 1. 839/10. 10 = M2 M2 = 0. 182M 2. 0. 202 + 0. 199 + 0. 182/3 = 0. 194 = M average 3. 0. 08233 – 0. 194 x 100/0. 08233 = 135. 63 percentage error 4.The main concept of this lab was to calculate the unknown molarity of an acid through titration. 5. Some of the experiment performed was to determine the concentration of an unknown concentration of an acid through titration by adding a second known concentration acid that will react with and cancel the first one. The endpoint of the titration will allows you to calculate the original concentration. 6. The dilution equation of M1xV1=M2xV2 was required to solve for the molarity of the hydrochloric acid where M1=NaOH(molarity), V1=NaOH(vo lume), M2=HCl(molarity), V2=HCl(volume). . The lab was successful in the properly changing color to represent a stoichiometric end point through titration. The dilution equation was then used to calculate the unknown molarity of one of the acid. The calculated results weren’t easily compared due to their decimal placing.

Putting the Enterprise Into the Enterprise System

Davenport’s article â€Å"Putting the Enterprise into the Enterprise System† discusses the pros and cons of Enterprise Systems. These systems gather data—manufacturing, sales, logistics, financial, etc. , and then pull this data into a central warehouse that helps companies make informed business decisions. However, the Article’s main theme is, that while these can be powerful tools for an organization, the adoption of a cookie cutter solution may be counterproductive.The part that most interested me was the Article’s discussion that very often a software system designed by the software experts may, in fact, remove the competitive edge of that company. While we tend to think of computing systems as enhancing operations and making them more efficient through faster communication, automation, removing the need for people, etc. , I had never thought of them as having the potential to remove a company’s competitive advantage.Competitive advantage , of course, is doing something different that makes your company better than the others. The difference, as cited in the Article, is typically the service, speed of delivery, etc. , and not the product itself. If, however, you and your competitor all sign up for the same or similar systems that define your business methods, then you begin to operate the same. Now all you have to compete on is price, which is going to squeeze margins.Of course there is a way around this, as the Article discusses, and that is to customize the system to match your existing processes and differentials so that you get the benefits of the efficiencies where you want them, but still maintain the uniqueness that makes your customers continue to come to you. This Article should be read by any company that is about to embark on the integration of an Enterprise System into their organization.The Article gives a lot of good pointers, particularly on the last page of the items to consider and the need for peopl e who truly understand the company’s methods of operations and DNA to ensure that these carry on even after the software is introduced. For the cost investment of such software, it is vitally important that an organization comes out with a product that makes them better and stronger and doesn’t get pulled down to be just another one of the pack.

Argumentative Essay Essay

  Ever since the war on terror our government continues the abuse of human rights by, always tracking individuals and labeling them, practicing lock downs of cities for when they really need it, and always adding to the list of freedoms there taking away from us. Most people don’t see it as that many people see it still as a war against people that terrorized America. Soon after 9-11 the United States best computers where hard at work beginning a process to find and label terrorist in America and by doing so they invaded everyone’s privacy by constantly scanning emails and texts, voice recognition software on all our phones, Facebook is primarily used to profile people and find more about their personal mind sets and likes. Our cell phones can trigger words that start voice recording software so anyone can listen in on our calls. Right after the Boston bombing the government exercised martial law by having everyone clear the streets and clearing house by house, no one could be outside without being considered a threat, that’s putting people on lockdown and testing out how well it works on big American city’s or towns and to see how well the people listened. One by one our freedoms are being taken away and no one can stop it, it’s part of the new technology and life we will have to grow and live into and our children. Ever since the terrorist act most of our freedoms where taken away right there, and as time goes on and we continue to let our government control us pretty soon we will have no freedoms what so ever and will be under full control as a people. Everyday new and better technology comes out that can help control America one way at a time. The war on terror has contributed to the growing abuse of human rights and no one will do anything to stop it. If we don’t come together as a hole to stop it people will soon be robots living under the control of one ruler or a group of people that decide everything about us.

Compair the thnen and christaller theory Essay Example | Topics and Well Written Essays - 1000 words

Compair the thnen and christaller theory - Essay Example The desire to make geography more scientific, or at least more intellectually acceptable as a discipline, led to the adoption of statistical methods as a primary research technique. Location (or spatial) analysis, as this new aspect of geography is called, seeks to analyze and explain the factors that control humankind's spatial organization, specifically by statistical methods and models. Mathematically constructed models became tools useful to the geographer in coping with rapidly accumulating knowledge, and they could also be used to predict future trends or spatial patterns. This was not the first time statistics had been used for geographic research. As early as the 1920s and '30s, Torsten Hgerstrand in Sweden and Walter Christaller in Germany had used statistical techniques. Only in the 1960s, however, did significant growth in statistical methodology occur. Johann Heinrich von Thnen was born on June 24, 1783, was a German agriculturist. In 1826 he wrote Der isolierte Staat (The Isolated State), in which he proposed his theoretical model showing concentric belts of agricultural production surrounding a market center and demonstrating the relationship of commodity transportation costs to production location. Thnen laid the foundations of contemporary spatial theory. (Larry, 2004) This non-linear reformulation of the von Thnen model... model explicitly allows for input substitution and provides for the rate of production intensities to be determines endogenously by the profit maximizing behavior of the individual farmers. If the transport rate is constant and production occurs with constant returns to scale, then the rent function, under bid rent tenancy, or owner occupied farming, is indeed nonlinear and strictly convex to the origin. It is also possible to determine the spatial distribution of labor density as well as levels of crop yield in accordance with this basic model. It is not surprising that these results confirm the Dunn-Isard conjecture as the bid rent functions so determined assume a strictly convex form, and the intensity of cultivation does, in fact, increase toward the market center. Now the nonlinear von Thnen model can be formulated to conform to the logistics of industrial production in order to derive a non-agricultural rent function, also based on constant-returns-to-scale technologies. Firms in the urban sector go to the market center to obtain their raw materials, which were previously delivered there from the agricultural sector. Some firms specialize in the production of various intermediate goods which are also delivered to the market, where other firms purchase them for incorporation in their own products. Final goods are then delivered to the market for sale to the general public. Capital is introduced as a production input, the amount of which is explicitly governed by the price ratio of labor and capital. This "augmented" model ultimately generates comparable results with regard to the shape of the resulting rent function as well as the spatial distribution of levels of production and employment and therefore the densities of capital and labor. Although based on
