GPS System Essay Example for Free

GPS System Essay The United State for Department of defense is the one that come up with Global Positioning System (GPS). It is a satellite navigation system which is build up by 24 satellites which are networked. It was initially intended for military application for the department of United States and around 1980s the system was allowed to be used by people who are even not in the military arena. A GPS receiver usually calculates its position by knowing the time when the signals are being sent by the GPS satellite to the atmosphere. The first satellite navigation system which was used by the united state navy was taken in to test by the year 1960. They did it by the use of constellation of five satellites. At this time the system was unable to place accurate clock and they come up with a new satellite called Timation satellite. This satellite was able to accurately calculate the clock and provide a good time when the signal was sent. The GPS system is powered by the use of solar and they still have batteries to be used in case of eclipse. How it works The GPS satellites go round the earth two times a day and in the process it transmits signal information to the ground. On the other sides the GPS receiver acquires this information and calculates the user’s the proper location. GPS system has over the years been developed and it has become more accurate as compared to some years back. When it comes to time keeping you will find that most clocks are synchronized to be able to move well with universal time where the clock is set in to GPS time. GPS System in our case In our case the GPS system can actually be useful to the NYC subway and bus system. The NYC subway will position post along the road and trail as well where bus stops and train are situated respectively. At each stage of the station where those boards containing instruction are elevated in a strategic position such that every body can see it as well as read it. It should use signs that each and every passer is able to interprets or provide avoice which is being heard by all the passengers. The signal signs can be inform of arrows showing the direction in which the train or bus is moving along with the time when the bus will be approaching. NYC subway being a central system for receiving the signal and transferring them to the required destination effectively, then passengers will be able to know when the bus is approaching. May be it can show the time and give a notice, so that, passengers can as well prepare themselves for a board. NYC subway should closely monitor the system to avoid the occurrence of differences by the passengers on which and when to board the bus. They can be able to control the system by making sure that each and every step leading to arrival of signal is properly coordinated by the bus management. People are now able to access the directions on where their destination is situated by even the click of the mouse, where one can Google and find the solution. Transit is well coordinated within the NYC and makes it easy and encourages more people to use the GPS system as a result of its efficacy. Conclusion By the use of GPS System there can be less confusion in the bus station in town of New York because every bus will come at a required time and the passengers for that specific bus will have been arrived. There exists a program where no delays are made to people who want to travel to their destination at the time when they have planned earlier. Over the years GPS system has been improved and tested for better results especially by the NYC subways where is has been a great help to the transport system. Many companies are now developing the idea of using the DPS system over the world due to its efficiency and safe time. Reference Michael .

The Song Dynasty :: essays research papers

The Song Dynasty The Song dynasty lasted over 300 years, from 960 to 1279. Their history is divided into two periods of Northern and Southern Song. The Song period was one of China's most peaceful and prosperous era. However the Song government was corrupt and weak.   Ã‚  Ã‚  Ã‚  Ã‚  The Song Dynasty, or Sung Dynasty was a period in which the Chinese government was very weak. In the beginning General Chao K'uang-yin, also known as Sung T'ai Tsu, was forced to become emperor in order to unify China. Sung T'ai Tsu created a national army under his direct control. He, and only he had control of the military. Once he had passed away his less competent successors were unable to keep the military under control, the military increasingly lost prestige. The weakening of China's military, coincided with the rise of strong nomadic nations on the boarders.   Ã‚  Ã‚  Ã‚  Ã‚  During the same time of the military's loss of prestige, the civil service rose in dignity. This was an examination system that had been restored in Sui and T'ang and was further elaborated and regularized. Selection examinations were help every three years at the district, provincial, and metropolitan levels.   Ã‚  Ã‚  Ã‚  Ã‚  Only 200 out of thousands of applicants were granted the jinshi degree. This was the highest degree and appointed on government posts. From this time on, civil servants became China's most envied elite, replacing the hereditary nobles and landlords.   Ã‚  Ã‚  Ã‚  Ã‚  The Song dynasty only extended over to the parts of earlier Chinese empires. The Khitans controlled the northeastern territories and the His Hsia controlled the northwestern territories. The Song emperors were unable to recover these lands so they were forced to make peace with the Khitans and the Hsi Hsia. They gave massive amounts of payments to the barbarians, under these peace terms, it depleted the state treasury and cause heavy payments on taxpaying peasants.   Ã‚  Ã‚  Ã‚  Ã‚  About 100 years after the Songs first started ruling over China, their government started to go through a major decline. Officials that held important government positions were corrupt. Wealthy merchants that became rich from foreign trade found ways to avoid paying taxes. The peasants began to rebel when the heavy taxes were placed on them. The Song Dynasty had a lot of problems, in 1069 Emperor Shen Tsung appointed Wang An-shi as chief minister. Wang was a scholar who studied earlier Chinese governments. Wang noticed the corrupt government and made huge reform in the government. His reforms were based on the text of 'Rites of Chou'. Wang tried to get honest, intelligent officials by improving the university system. He made civil examinations more practical and reformed the merit system to reduce corruption among government officials.

Industrial Organization and Regulation of the Market

A market could be described in simple words as a place where buyers and sellers meet to exchange goods and/or services. In this context the market does not have to take a physical location. This has been made possible by advances in technology where it’s now possible to sell/by goods and or services over the telephone or through the internet.There are different types of markets and these markets are determined by many factors. In general we have two broad categories of markets; these are the industrial markets and consumer markets.Consumer MarketsConsumer markets are the markets for products and services bought by individuals for their own or family or domestic use. Goods bought in consumer markets can be categorised in several ways:†¢ Fast-moving consumer goods (â€Å"FMCG's†)†¢ Consumer durables†¢ Soft goods†¢ Services (e.g. hairdressing, dentists, childcare)Industrial MarketsIndustrial markets involve the sale of goods between businesses. These ar e goods that are not aimed directly at consumers. Industrial markets include†¢ Selling finished goods†¢ Selling raw materials or components†¢ Selling services to businessesIndustrial markets often require a slightly different marketing strategy and mixOrganization and Regulation:In every kind of market situation mistakes just like in the public sector can and do occur. When governments fail we call it government failure but when markets fail we call it market failure. Of course, most deviations from the ideal are minor and do not impose significant costs on society. But when deviations are significant there is often a call for government to do something about the problem. For example, markets can deviate significantly from the competitive ideal — e.g., firms may acquire significant market power, undertake deceptive practices or collude like cartels in order to make abnormal profits.When it comes to regulation and organization of markets there are usually a few goals that every industry and or government wants to achieve. These include consumer protection (from sub-standard or harmful products), price controls (to prevent over exploitation of consumers and unhealthy competition), prevent counterfeiting and black market trading. In essence thus regulation involves administrative guidance of the market in order to make it more efficient.By efficiency we mean Economic efficiency and Economic efficiency is something much more than producing goods at the lowest possible cost. It involves providing individuals with the goods and services they desire, in the quantities, qualities, places, and times they desire them, with the least use of society's scarce resources. Economists argue that if markets are competitive, if accurate information is available, if resources are mobile, and if individuals engaging in the transactions bear the full costs and receive the full benefits of their transactions, economic efficiency will be achieved.Regulation can either be internal or external. Internal regulation usually involves regulation within the industry especially in the field of competition. External regulation involves control through government policies.External regulation includes:Social Regulation.This involves government regulation to contain negative externalities. Environmental problems, like pollution and congestion, are hard to solve[1]. Due to this governments come up with measures to control this, these measures include: Rights to pollute and rights to use highways.Rights to PolluteCreating rights to pollute the air can – paradoxically – help to control pollution. A â€Å"right-to-pollute† solution for pollution control defines a right to pollute and allows that right to be bought and sold. In essence these rights are limited this makes their prices high. In order to avoid paying these huge amounts firms instead install pollution abatement equipments and these help reduce overall pollution.This means that the level of allowable pollution can be specified, as we now do for instance to limit sulphur dioxide emissions in the United States to combat acid rain.[2] Once pollution rights are defined and a given supply is established, a market price can be determined. Then those who can reduce pollution most efficiently, that is, for less than the value of a right to pollute, will reduce pollution and sell their rights to pollute to others. Those who face higher pollution abatement costs can buy the pollution rights and use them for permission to emit pollution.Thus, at market equilibrium, the price of pollution rights reflects the marginal cost of controlling pollution to the level that the available pollution rights will allow.Rights to Highway UseWe pay no price for highway use. We incur the private cost of a vehicle trip between two points, including not only fuel, oil, tire wear, and so on, but also the driver's (and passengers') time, and when congestion is serious that time compo nent goes up.[3] The familiar problem of excessive traffic congestion arises because each of us decides whether to make a highway trip on the basis of the average cost rather than the marginal cost of the trip to society.[4] An additional car can join a stream of cars on the highway and it will share in the average costs and delays of all the other cars. Yet that marginal vehicle causes delays to all the others, delays that the driver of the marginal vehicle does not take into account when joining the traffic stream.A solution to the highway congestion problem can come from assigning a property right in road use — a right to delay others, like the right to pollute. Electronic devices exist now that will record time spent on a road. When placed in vehicles, these devices function like the electricity meter in your house, but they identify the time and location of your road use[5]. Technology and economics combine in these devices to make billing drivers for road use feasible, and that can avoid excessive congestion.Such devices and fees are in effective use in Singapore[6] and many of us should expect to see them in our lifetimes. There are many other areas where social regulationWas introduced in clumsy forms – consumer protection for example – that are improving gradually, based on economicIdeas that improve information and market function.Economic regulation.Economic regulation in many markets has taken a form whereby the number of firms in an industry is determined by the government and the markets firms can serve are specified by the regulatory commission. Prices and rates of return are regulated and, importantly, entry into the industry is either forbidden or made very difficult by law. Thus economic regulation maybe in the form of antitrust laws or price fixation. In antitrust cases, courts follow either â€Å"per se† rules, under which certain facts determine guilt or innocence, or they examine circumstances more broadly and follow a â€Å"rule of reason† analysis, to determine the appropriateness of the observed behaviour.The per se procedure is quicker and easier, and of course it gives more precise guidelines to business firms, but it requires what lawyers call â€Å"bright line,† or clear, rules. The disadvantage of such per se rules is that they may be over or under inclusive. The alternative, rule-of-reason, analysis allows courts to examine the circumstances of each case. It is in these rule of reason analyses that economics is applied far better now than in the past.Limitations of regulation:  Regulation leads to increased costs of conducting business. The direct and indirect costs of regulation result in higher prices and increased costs of employing workers. These costs act as a tax on job creation and employment. They also cause a decrease in productivity. The higher business costs that result from regulation are passed along to consumers in the form of higher prices (indirect taxation). To the extent that lower income individuals spend a greater proportion of their income on the goods and services affected, the higher prices are in essence a form of regressive taxation.[7]Conclusion:The organization and or regulation of any market has its ups and down. Markets and governments always fail from time to time. Due to this a harmonious relation needs to exist between the government and industries. This requires that where regulation leads to increased.Reference:Ellerman, A. Denny, et al.

The Trouble with Geniuses - 763 Words

The Trouble with Geniuses Part One: Although both Chris Langen and Robert Oppenheimer were both geniuses, Oppenheimer had better life chances and more opportunities than did Chris Langan. Oppenheimer was born in a wealthy and well-known family and was in an upper social class. Therefore he had a richer cultural capital than Chris Langan because his parents taught him how to deal with adults and how to assert himself. They also encouraged him to take chances. For instance, when he has an opportunity to be a speaker at the New York Mineralogical Club, he was afraid and did not want to do it, but his father encouraged him to take the challenge. His parents encouraged and help Oppenheimer to prosper and grow and develop his genius.On†¦show more content†¦In turn, those cultural capitals affects the life chances that children encounter. Part Two: Parents influence their children in very many ways. Parents encourage desired behaviors and talents while discouraging those that are undesirable not necessarily to the children, but to the parents and adults in the real world.Desired behaviors are rewarded while undesirable traits and behaviors are met with punishment of some form. Our parents taught us how to be independent and to do things for ourselves. It was an advantage in that we don t need to depend on other people to get things done and we don t need to wait for an opportunity.This independence taught us to work hard for ourselves and to take charge of our own education and life. Part Three: Cutting music and art programs creates a large gap between opportunities for wealther children and lower class children. Children whose parents do not have the financial means to afford private art and music lessions have a greater disadvantage because they do not have the opportunities and resources to cultivate their talents. They could be the next Picasso, but because they did not have the means to express their genius and cultivate their talent, it never gets discovered. Only a very few lucky children will be able to prosper in their talents. Schools should provide another means of art and music classes.
