Calculating Distance Between Tow Points on Earth Surface Using Gps Coordinates

DISTANCE CALCULATION Because of the near-spherical shape of the Earth (technically an oblate spheroid) , calculating an accurate distance between two points requires the use of spherical geometry and trigonometric math functions. However, you can calculate an approximate distance using much simpler math functions. For many applications the approximate distance calculation provides sufficient accuracy with much less complexity. The following approximate distance calculations are relatively simple, but can produce distance errors of 10 percent of more. These approximate calculations are performed using latitude and longitude values in degrees. The first approximation requires only simple math functions: Approximate distance in miles: sqrt(x * x + y * y) where x = 69. 1 * (lat2 lat1) and y = 53. 0 * (lon2 lon1) You can improve the accuracy of this approximate distance calculation by adding the cosine math function Improved approximate distance in miles: sqrt(x * x + y * y) where x = 69. 1 * (lat2 lat1) and y = 69. 1 * (lon2 lon1) * cos(lat1/57. 3) If you need greater accuracy, you can use the Great Circle Distance Formula. This formula requires use of spherical geometry and a high level of floating point mathematical accuracy about 15 digits of accuracy (sometimes called double-precision). In order to use this formula properly make sure your software application or programming language is capable of double-precision floating point calculations. In addition, the trig math functions used in this formula require conversion of the latitude and longitude values from decimal degrees to radians. To convert latitude or longitude from decimal degrees to radians, divide the latitude and longitude values in this database by 180/pi, or approximately 57. 9577951. The radius of the Earth is assumed to be 6,378. 8 kilometers, or 3,963. 0 miles. If you convert all latitude and longitude values in the database to radians before the calculation, use this equation: Great Circle Distance Formula using radians: 3963. 0 * arccos[sin(lat1) * sin(lat2) + cos(lat1) * cos(lat2) * cos(lon2 lon1)] If you do NOT first convert th e latitude and longitude values in the database to radians, you must include the degrees-to-radians conversion in the calculation. Substituting degrees for radians, the formula becomes: Great Circle Distance Formula using decimal degrees 963. 0 * arccos[sin(lat1/57. 2958) * sin(lat2/57. 2958) + cos(lat1/57. 2958) * cos(lat2/57. 2958) * cos(lon2/57. 2958 -lon1/57. 2958)] OR r * acos[sin(lat1) * sin(lat2) + cos(lat1) * cos(lat2) * cos(lon2 lon1)] Where r is the radius of the earth in whatever units you desire. r=3437. 74677 (nautical miles) r=6378. 7 (kilometers) r=3963. 0 (statute miles) If the software application or programming language you are using has no arccosine function, you can calculate the same result using the arctangent function, which most applications and languages do support. Use the following equation: 3963. 0 * arctan[sqrt(1-x^2)/x] where x = [sin(lat1/57. 2958) * sin(lat2/57. 2958)] + [cos(lat1/57. 2958) * cos(lat2/57. 2958) * cos(lon2/57. 2958 lon1/57. 2958)] If your distance calculations produce wildly incorrect results, check for these possible problems: 1. Did you convert the latitude and longitude values from degrees to radians? Trigonometric math functions such as sine and cosine normally require conversion of degrees to radians, as described above. 2. Are the equations implemented correctly with necessary parentheses? Remember the old math precedence rule MDAS multiply, divide, add, subtract. 3. Does your software application or programming language provide sufficient mathematical accuracy? For best results, you need about 15 digits of accuracy. 4. When you imported the data from the text files your latitude/longitude values may have been truncated. Make sure you did not lose any of the digits to the right of the decimal point during import. 5. Have you lost any precision of your decimal values due to rounding during importing or calling custom math functions

Short answers about Introduction to Political Economy Essay - 2

Short answers about Introduction to Political Economy - Essay Example Another cause of monopolies occurs when one firm expands to the point where it has tremendous economies of scale; other competitors drop out of the market because they cannot compete. Companies are likely to collude with each other if there are very few firms in an industry. Because of this, a change in one firm is likely to result in a change in another firm so that market forces remain the same. On the other hand, companies are likely to compete with each other when there is free market economy that allows consumers to pick and choose from many different companies. Regulations can cause a huge shift in the market, particularly in the labor market. When the government stipulates that employees must certain type of social security, employers have to respond to those changes. This can often mean that a business downsizes because it cannot afford to employ the same number of workers. Regulations primarily stifle business because of all the extra red tape that comes along with it. Capture theory stipulates that a government agency may allow the industry that it is charge of to dictate policy that favors the industry as a whole. On the other hand, public-interest theory deals with the interest of consumers. For example, when the market is not efficient as it could be, a regulatory body can act to make changes in regulations. The abolition of private property and the application of all rent to public purpose is designed for zoning laws that allow the government to own property. Progressive income tax makes all Americans pay their fair share. The abolition of all rights of inheritance offers limited inheritance through tax statues. Confiscation of property of rebels allows the government to seize property belonging to terrorist groups. Centralizing the credit system gives the state control over loans. Centralizing communication and transport allows the state to set regulations. Corporate capacity allows land to be improved. Equal labor

Martin Luther King and the Church Essay Example | Topics and Well Written Essays - 250 words

Martin Luther King and the Church - Essay Example All social groups ranging from the ruling class to the peasant class had a strong reason to accept Luther’s reasons and support him. The princes and kings resented the overarching control of the Church, while the peasants resented the wealth of the Church and revolted against the social, political and religious authorities. It was the context and time that played a huge role in the success of Luther. As reformation spread from Germany throughout Europe, it gave rise to violence, religious struggles, wars and civil unrest. The widespread conflicts involving Catholics killing Protestants, Protestants killing Catholics and the Thirty Years War can certainly not be justified, whatever the reason was, given the bloodshed and other serious consequences. However, Reformation alone cannot be held solely responsible for these wars as even otherwise there would have been political and social struggles leading to wars at that time in Europe. There was an increasing social and political discontent all over Europe. Reformation offered the opportunity to either establish authority or to break away from it. This context should not be ignored while discussing the stormy period in Europe during the Reformation. Such a political and social unrest should be seen as a significant trigger for the wars and civil unrest all over Europe during Reformation. Brutal wars and bloodshed cannot be hailed or celebrated, but without Reformation, Europe would not have undergone significant changes in its political, economic and social institutions. Change is inevitable, and Reformation was one such a change within the Church but one which led to a larger scale conflict and war because of the contemporary socio-political conditions. It was only an opportunity seized by the society of that time, and if it had not been a Reformation, it would have been some other revolution that would have erupted to

Slavery and the Caribbean :: Slavery Essays

Slavery and the Caribbean Europeans came into contact with the Caribbean after Columbus's momentous journeys in 1492, 1496 and 1498. The desire for expansion and trade led to the settlement of the colonies. The indigenous peoples, according to our sources mostly peaceful Tainos and warlike Caribs, proved to be unsuitable for slave labour in the newly formed plantations, and they were quickly and brutally decimated. The descendants of this once thriving community can now only be found in Guiana and Trinidad. The slave trade which had already begun on the West Coast of Africa provided the needed labour, and a period from 1496 (Columbus's second voyage) to 1838 saw Africans flogged and tortured in an effort to assimilate them into the plantation economy. Slave labour supplied the most coveted and important items in Atlantic and European commerce: the sugar, coffee, cotton and cacao of the Caribbean; the tobacco, rice and indigo of North America; the gold and sugar of Portuguese and Spanish South America. These commodities comprised about a third of the value of European commerce, a figure inflated by regulations that obliged colonial products to be brought to the metropolis prior to their re-export to other destinations. Atlantic navigation and European settlement of the New World made the Americas Europe's most convenient and practical source of tropical and sub-tropical produce. The rate of growth of Atlantic trade in the eighteenth century had outstripped all other branches of European commerce and created fabulous fortunes. An estimate of the slave population in the British Caribbean in Robin Blackburn's study, The Overthrow of Colonial Slavery: 1776-1848, puts the slave numbers at 428,000 out of a population of 500,000, so the number of slaves vastly exceeded the number of white owners and overseers. Absentee plantation owners added to the unrest. Rebellion was common, with the forms including self mutilation, suicide and infanticide as well as escape and maroonage (whereby the slaves escaped into the hills and wooded interiors of the islands and set up potentially threatening communities of their own. See references in Wide Sargasso Sea). Jamaica holds the record for slave revolts, with serious uprisings in 1655, 1673, 1760 and continued disquiet after that. The documentation of revolts in Trinidad is less complete, but we know of at least one serious plot in 1805. Guiana was actually governed by a slave named Cuffy for a year after the revolt in 1763, and Barbados also had numerous plots, including s ix between 1649 and 1701.

Bus 630 Week 1 Discussion

BUS630 WEEK 1 Ashford University MANAGERIAL ACCOUNTING: This week students will: 1. Explain the primary ethical responsibilities of the management accountant. 2. Illustrate the key principles of managerial accounting including cost concepts. 3. Distinguish between the behavior of variable and fixed cost. 4. Explain the significance of cost behavior to decision making and control. 5. Determine the necessary sales in unit and dollars to break-even or attain desired profit using the break-even formula. FINANCIAL VS MANAGERIAL ACCOUNTING-Financial accounting is the branch of accounting that organizes accounting information for presentation to interested parties outside of the organization. The primary financial accounting reports are the balance sheet (often called a statement of financial position), the income statement, and the statement of cash flows. The balance sheet is a summary of assets, liabilities, and shareholders’ equity at a specified point in time. The income stateme nt reports revenues and expenses resulting from the company’s operations for a particular time period.The statement of cash flows shows the sources and uses of cash over a time period for operating, investing, and financing activities. Managerial accounting is the branch of accounting that meets managers’ information needs. Because managerial accounting is designed to assist the firm’s managers in making business decisions, relatively few restrictions are imposed by regulatory bodies and generally accepted accounting principles. Therefore, a manager must define which data are relevant for a particular purpose and which are not. In managerial accounting, however, the segment is of major importance.Segments may be products, projects, divisions, plants, branches, regions, or any other subset of the business. Tracing or allocating costs, revenues, and assets to segments creates difficult issues for managerial accountants. Two important similarities do exist. The tra nsaction and accounting information systems discussed earlier are used to generate the data inputs for both financial statements and management reports. Therefore, when the system accumulates and classifies information, it should do so in formats that accommodate both types of accounting.Discuss a possible negative managerial scenario that the regional manager may be sensing. The Regional Manager is piecing together trends and abnormalities in order to predict the near future of store #9. At a glance, we determine that store 9 run by an effective manager with a successful track record. However, the lack of investment in training signals an attempt to cut overhead cost in order to show a larger store profit. Cutting employee training may be an effective tool for the short term but may create issues in the future. Additionally, we see that the Store has decided to withdraw from several costly, but high visibility events.Again, this may be a reduction in variable cost in order to reduc e store overhead in the short term and increase profitability. The Regional Manager’s concern is that the entire company profits from these community events, not just the single store, and therefore, the impact may be detrimental to sales in multiple areas. Lastly, we see that store #6 has increased its operating costs since the store manager in question departed. This signals an issue consistent with the concerns above that this manager simply aims to reduce overhead as low as possible in order to increase the overall store profit.Might the manager of Store 9 be an exceptional manager? Although on the surface, the three trends above may appear to be negative; this store manager may in fact be a very effective manager. For example: Perhaps instead of accounting for the trainee’s hours as overhead in training costs, he has put that individual in a position to learn-on-the-job, therefore, making the employee’s working hours into a direct labor cost and minimizing overhead. When it comes to advertising, we saw the manager spent most of his advertising dollars early in the year.It may be possible that the manager elected to spend his variable expense advertising dollars during a time period where they would produce the most sales, and then tapered off his advertising dollars during a time period of steady business flow. Lastly, the cancellation of high visibility events may have been due to the determination that cost was not yielding substantial sales or visibility. Despite this fact, it stands to reason that a store manager would inform a regional manager of any choices having a broader impact to the overall company.If there was a lack of communication here, I believe it is to the detriment of the store manager’s credibility. What are the ethical implications of the scenario? Variable Cost defines the cost of a single assembled product based on the materials consumed and labor invested directly in unit production. To illustrate our po int, we can say that making a single baked potato with all of the fixings will cost $3. 00 to produce (potato, sour cream, chives, plate, fork, napkin and labor). If we decide to go into the baked potato business, we must then sell these potatoes for at least $3. 00 per unit.Any less would cause us to lose money on the endeavor. This cost cannot be made up by increasing volume of sales. Judy Koch discussed the fact that bulk purchases can benefit you reduce these variable costs. If we decided to purchase potato-making materials in larger quantities and hired more workers to produce these products, we could then possibly produce our product for a lower Variable Cost based on the new price. Fixed cost will remain the same no matter how our potato shop does. As an example, our potato restaurant rental costs will be the same whether we sell one hundred potatoes or zero potatoes per month.The electricity, the heating costs, the manager’s salary. All of these factors will stay cons istent no matter how many units we sell. Judy Koch’s statement is in reference to the fact that these costs are indeed changeable, however, they do not vary per unit sold. We can decide to upgrade our successful restaurant and pay higher rental fees, the government can increase our tax liability and we can hire more management. None of these costs will increase if we sell more potatoes. They are independent of unit sales.

My Classroom Management Plan Essay - 2727 Words

A classroom management plan is essential in order for a teacher to affect student learning. An effective plan will take into consideration many factors. First and foremost the focus must be on the content of the material to be taught. The teacher must plan the academic lessons thoroughly. It is important to keep your eye on the ball. Your goals for the academic progress must be at the heart of this plan. Therefore you must know where you are taking this class, before a path can be chosen. In this respect, I share the philosophy of William Glasser. He believes that the key to classroom management is a vital interesting curriculum. A need for this curriculum must be demonstrated to be relevant in their everyday lives, and†¦show more content†¦They all feel that establishing a classroom community is important. After all the need for belonging is very important. Being an integral part of a community is belonging on a very large scale. For students or anyone to feel l ike they are members of a community, they must have made an investment in it. Albert believes that the contribution to the code of conduct is a sufficient contribution to form a community. Gordon suggests that contracts and agreements establish communities, as does Dreikurs. Kohn places the emphasis on cooperative learning, where academic contributions are the best way to forming a safe comfortable community. I think that they are all correct, but I believe that even a bigger investment could be made. Just like any community, it is important to have leaders and assignment of responsibilities. The method and process for the selection of these should be determined by the social contract, but I would like to see these issues put on the table. Here again I agree with Jones in practice but not theory. I like student led bell work and studentassigned chores. I think that if the leadership roles and chores were student generated, regulated, and rotated, everyone would eventually h ave a physical investment in each other and in the classroom itself.

The Controversial Issue Of Abortion - 1088 Words

Abortion is one of the most controversial topics in today’s world. With the evolving moral standards of society, abortion is becoming more and more justified. Abortion is the deliberate termination of a human pregnancy, most often performed during the first twenty-eight weeks of pregnancy. People don’t seem to realize that abortion can ultimately have the best overall consequences. This topic should be viewed from a consequentialist view, or from the moral worth depending on the positive or negative value of the consequences. The choice of abortion doesn’t matter as much as the consequences of the choice itself. While some consider abortion murder, others believe it as saving a life. It can save a mother from an unwanted pregnancy and it can save a child from an unwanted future. A woman has the right to choose abortion if they believe it is necessary and dispose freely of their own body. I will begin by arguing that abortion can have the best overall consequence when a mother and a child’s future is uncertain. A child shouldn’t be put through a rough childhood if the mother is aware of harsh living conditions or not being able to physically, mentally or economically support a child. For instance, if a woman was raped, the mother would be unable to raise a child because of the emotional pain caused by the rape, and the child would just be a constant reminder of what happened which can lead to abuse of the child. Or let us say that the woman is in an abusive relationship withShow MoreRelatedThe Controversial Issue Of Abortion878 Words   |  4 Pagesrecent discussions of abortion, the controversial issue has become whether or not women should be given the right to take their unborn child’s life away.
