Over 62,000 vending machines using eport connect cashless payment and USAT’S eport point- of-sale devices have got the ISIS smart tap technology enabled. The technology is meant for rewards access, loyalty programs and contactless payments (Mobile Payments Today, 2013) The NFC technology uses wireless means to exchange data between an NFC -enabled device and other devices. Verizon customer can use the Android Smartphone as their wallet that safely stores the virtual versions of their debit cards and credit cards. It also serves as a home to coupons, loyalty cards and some other special offers (Mobile Payments Today, 2013). For one to use the ISIS mobile wallet he/she require the following materials; A T-Mobile Advanced SIM Card which is capable of information storage and protection, regarding payments and any other sensitive wallet details. There is also need for An ISIS enabled Smartphone that has support the NFC technology in the transfer of payment details at a check point. A major setback for the new subscribers is that you will have or need to purchase a new Advanced SIM, which could be costly (Bunton, 2013). Some of the locations where this ISIS Mobile Wallet can be used include; Office Deport, Coca-Cola vending machines, American Apparel, T-Mobile and many others. This mobile app enables the users to store the virtual versions of their staff in there wallets, in the Smartphone. The app enables the customers to maintain their loyalty information, payment information, money saving offers and discount information in one place that is convenient. For example; New American Express Service Account holders who sign for an account through the ISIS Mobile wallet by the end of the month of June will receive

Electrical Systems Essay The purpose of this laboratory test was to make comparisons between theoretical and practical results and to develop a greater understanding of factors affecting the operation of complex AC networks. The results from the Series Parallel RC network have minimal errors, however the small differences are mainly due to slight machine and human error. The DSO should be turned on at least a day earlier to achieve steady values, therefore this not being done, could have caused some of the errors. When measuring the change in time, it is difficult to determine the exact point at which the curve crosses the line. Because there is two points to determine, the error is then doubled. These factors also affect the results of the RLC circuit, however the inductor causes the main errors in this circuit. At low frequencies, the inductor interferes with the signal generator, not only causing the values to be slightly wrong but also projects a graph that doesn’t completely represent a sinusoidal function. This causes the change in time to be incorrect and therefore the phase angle. The inductor is also the equivalence of a 24 resistor, which will consequently alter the results. Whilst measuring voltage, it is important that the component is connected to ground. The ground point is considered to have a voltage of zero and is therefore the reference point. If this was not the case and the component was not connected to the ground, there would not be a reference point of zero, rather the voltage of the terminal it is connected to. To measure the magnitude and phase without shifting the ground, a value could be directly read off the graph. The phase would be the same, as it is just compared to the current. Kirchhoff’s voltage law (KVL) can be proven if the voltage of the source is completely consumed through the circuit. Calculations, found in the appendix, prove that the series parallel RC network follows KVL, as the voltage consumed by the resistors and capacitors approximately equals the voltage supplied by the source. There is only an error of 2. 4% and a phase difference of half a degree, therefore it can be concluded that KVL holds for the measured values for this circuit. Calculations, found in the appendix, prove that the RLC Circuit follows KVL, as the voltage consumed by the resistor, inductor and capacitor approximately equals the voltage supplied by the source. There is only an error of 1. 02% and a phase difference of 0. 86Â °, suggesting that the circuit is an accurate representation of KVL. Kirchhoff’s current law (KCL) can be proven if the current leaving a node is equal to the current entering it. Calculations, found in the appendix, prove that the series parallel RC network follows KCL, as the current through IR2 added to the current through IC2 is approximately equal to the total current. There is only a 0. 647% error and a phase difference of 0. 903Â °, suggesting the KCL holds true for the measured values for this circuit. Calculations, found in the appendix, prove that the RLC circuit follows KCL. The current supplied by the source and the current through the resistor, inductor and capacitor are all approximately equal. The errors are 0%, 2. 3% and 7. 99% and the phase differences are 0Â °, 3. 15Â ° and 14Â °. This does suggest the KCL holds true but there are slight errors in our measurements. The large errors are either due human error, machine error of inductive interference. This laboratory demonstrates that results can be measured very accurately with simply resistors and capacitors but that inductors largely affect the circuit’s performance. Our results prove the DSO performs accurate measurements, but allowances need to be made for the inductors’ resistances and signal interference.

Causes of the English Civil War :: essays research papers

The civil war broke out in 1642, and was a war that is within a country, it has many reasons for happening. This essay will explain and categorise the main cause’s fop the civil war. I will start by listing the genres of events. In the 1640’s power and politics were vital for social standard and anyone with power was important and respected so naturally and event such as the civil war would have had politics as one of the main issues for happening. Charles becoming king was obviously a cause because it was his decisions that influenced the war itself and him who raised the flag. Also in 1629 Charles decided to close down parliament because he felt they were exerting too much power than they should, also it almost seems as if Charles is afraid of parliament or jealous because he feels that he is entitled to the â€Å"divine right of kings† and seeing parliament using all this power made him feel as if he was less and not as important. This was then followed by the â€Å"eleven years of tyranny† which ended in 1640 when he recalled parliament due to shortage of money and mistakes he had made. An interesting decision Charles made was to marry Henrietta a foreign royal, some people would have said this was purely religiously influenced because she was a catholic and people feared he married her because his desire was to make England catholic. Others have said that it was a power driven choice because he wanted to unite the two countries and gain more power. There are other more religious based events such as when Charles ordered Henry Laud to make a new prayer book which was to be read around the England. This caused an outrage between his people who could now no longer trust him. As if this wasn’t enough he then ordered the book to be read in Scotland this was in 1637 and was possibly one of his worst choices, this was because at the time Scots were angry that Charles hadn’t turned protestant because he was raised as protestant and on top of that they were extremely insulted that Charles would even for a second believe that they would accept this book. This t hen resulted in rampage and violence so the book was taken away. The saying â€Å"money is the root of all evil† applies strongly in the making of the civil war.

Computer Generated Evidence in Court :: Computers Technology Courtroom Essays

Computer Generated Evidence in Court Introduction We are living in what is usually described as an 'information society' and as the business community makes ever greater use of computers the courts are going to find that increasingly the disputes before them turn on evidence which has at some stage passed through or been processed by a computer. In order to keep in step with this practice it is vital that the courts are able to take account of such evidence. As the Criminal Law Revision Committee recognised, 'the increasing use of computers by the Post Office, local authorities, banks and business firms to store information will make it more difficult to prove certain matters such as cheque card frauds, unless it is possible for this to be done from computers' (CLRC 1972, para 259). Admissibility The law of evidence is concerned with the means of proving the facts which are in issue and this necessarily involves the adduction of evidence which is then presented to the court. The law admits evidence only if it complies with the rules governing admissibility. Computer output is only admissible in evidence where special conditions are satisfied. These conditions are set out in detail in section 69 of the Police and Criminal Evidence Act (PACE) 1984 (see further Nyssens 1993, Reed 1993 and Tapper 1993). In general the principles of admissibility are that the evidence must be relevant to the proof of a fact in issue, to the credibility of a witness or to the reliability of other evidence, and the evidence must not be inadmissible by virtue of some particular rule of law (Keane 1994, pp 15-20; Tapper 1990, pp 51- 61). Real evidence usually takes the form of some material object (including computer output) produced for inspection in order that the court may draw an inference from its own observation as to the existence, condition or value of the object in question. Although real evidence may be extremely valuable as a means of proof, little if any weight attaches to it unless accompanied by testimony which identifies the object in question and explains its connection with, or significance in relation to, the facts in issue or relevant to the issue. This is illustrated in the case of R v Wood (1982) 76 Cr App R 23 where the appellant was convicted of handling stolen metals. In order to prove that metal found in his possession and metal retained from the stolen consignment had the same chemical composition cross-checking was undertaken and the figures produced were subjected to a laborious mathematical process in order that the percentage

Mo-tzu’s Argument Against Music Essay

Mo-tzu (also called Mozi, Moz, or Micius in Latin) was a renowned philosopher in China back in about 390-470 B. C. during the time of the Hundred Schools Thought (Wikipedia, 2007). Having founded Mohism, he argued about the inadequacy of Confucianism and Daoism on the need for a mortal being to self-reflect and meditate upon oneself. He also insisted that, instead of rituals and singings, what human beings need are acts of authenticity that does not include the use of drums, zithers, and pipes. He, therefore, stressed out: â€Å"To have music is wrong† (Par. 1, Book VIII, Chapter XXXII). Main Body We all agreed that Mo-tzu presented a very well thought of argument against music. This can be seen when he stated, Although the body knows they are comfortable, the mouth knows they are gratifying, the eyes know they are delightful, and the ears know they are pleasing, yet they are found not to be in accordance with the deeds of the sage-kings of antiquity and not to contribute to the benefits of the people at present. (Par. 1, Book VIII, Chapter XXXII) In saying this, he implied that music did not have anything to do with the greatness and success of the sage-kings†¦ that it did not fulfill the basic needs, unlike the boats and the carts that were built from the same contribution of the ancient citizens. It slowed production by wasting labor on things that are of no use. He stated, The levy of heavy taxes on the people to construct the big bell, the sounding drum, the ch’in and the she, and the yY and the sheng, is not at all helpful in the endeavor to procure the benefits of the world and destroy its calamities. Therefore Mo-tzu said: To have music is wrong. (Par. 3, Book VIII, Chapter XXXII) Mo-tzu is absolutely correct. Yet in spite of this, if people accept that music is not useful in acquiring the needs of this world, such as food, clothing, and rest (Par. 3, Book VIII, Chapter XXXII), then they must also understand that, just like music, philosophy is just as useless in acquiring the needs of this world, such as food, clothing, and rest (Par. 3, Book VIII, Chapter XXXII). In fact, as compared to music, philosophy presents greater cause for men to think deeply, and run into sickness and chaos (with oneself or with the society) that, in turn, makes them more prone to hunger, to state of undress, and to unrest. What philosophy has failed to give men, music could give with just a stroke or a beat of the instruments. True, musical instruments cannot be directly eaten and cannot cloth the naked, yet the instruments were also considered treasures in the long ago, which means that the owners could sell it for a chance to buy food or clothing in exchange of the musical instruments. When it comes to giving rest, however, music has the capability to give rest to those who are bothered psychologically or biologically. Philosophy, on the other hand, cannot be exchanged for food, clothing, or rest, since it all runs in the mind of the wise men. Thinking about the statements of the wise will just make men hungrier, poorer with less clothing, and more troubled. I, therefore, stress out—to have philosophy is totally wrong! Conclusion Mo-tzu failed to acknowledge that music is an art that sprouts from the very being of the individual. It is like painting, sculpture, literature, or the use of colors. It is an expression of what human beings feel, think of, believe in, or acknowledge. It comes from the mind. With this, it is very obvious that to say that music is totally wrong would also mean that philosophy is totally wrong, since the latter is also an expression of what human beings feel, think of, believe in, or acknowledge. Music comes from the mind just as philosophy comes from the mind. The only difference is that philosophy centers on chosen beings—those who are more gifted and wise—than when compared to music, which is so ordinary and can be expressed by anyone who dreams of expressing himself. Yet they both come from the mind. Even if both have their own sides of gains, both are totally incapable of destroying calamities.

Globing Warming essays

Globing Warming essays Global Warming: Societys Warning I feel strongly that global warming is affecting my community because its effects reach across every town in every country across the entire planet. Global warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For the last 10,000 years, the Earth's climate has been extraordinarily beneficial to mankind. "Humans have prospered tremendously well under a benign atmosphere," (Bates 28). Today, however, major changes are taking place. People are conducting an inadvertent global experiment by changing the face of the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth's surface. All of these activities are unfavorably al tering the composition of the biosphere and the Earth's heat balance. If we do not slow down our use of fossil fuels and stop destroying, the forests, the world could become hotter than it has been in the past million years. Average global temperatures have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century. The warning will be the greatest at the higher latitudes of the Northern Hemisphere, with the largest temperature rises occurring in winter. Most areas will experience summertime highs well above 100 degrees Fahrenheit. New temperature records will be set each year. As a possible prelude to global warming, the decade of the 1980's has had the six hottest years of the century (Erandson 18-22). Atmospheric disturbances brought o...

Absolutism and Louis 14 essays

Absolutism and Louis 14 essays Absolutism and Louis XIV Louis XIV of France had had both a long and powerful reign on the throne. He was able to achieve this due to the development of absolutism in France. Absolutism is defined as the political idea that absolute power should be vested in a single ruler. The whole idea of absolutism originally came from philosopher Jean Bodin in the 16th Century. Louis ¹ absolutism developed with four major parts: The breeding of a strong and controlled military, The building of Versailles to control the nobility, The selling of nobility, and The appointed of an advisor. The first step to the creation of Louis ¹ absolutism was the building of the military. Louis made war an activity of the state. He made sure all armed persons in France fought only for him. Much of this idea that law and force within a country should be monopolized by the lawful king came from Bishop Bossuet. This idea led to domestic peace. Louis also put the artillery organically into the army, systematized the military rankings and grades, and clarified the chain of command, putting himself at the top. The government also supervised recruiting and took most of the responsibility for equipping, provisioning, clothing, and housing the troops. Louis also established civilian administration in military. Under Louis, the army went from about 100,000 soldiers to about 400,000. The military made many gains under Louis, thus helping him gain absolutism. Louis built Versailles as both a relaxing and entertaining place for himself, and to disable the nobles and gain an edge in absolutism. Louis demanded that nearly half of France ¹s 10,000 nobles be present at court everyday for  ³role. ² These 5,00 nobles were those who were thought to pose the most risk to Louis XIV ¹s absolutism. Louis reputedly said to these nobles  ³If I cannot see you [at court], you do not exist. ² As a result, the nobles spent much time at Versailles and were unable to get into any  ³political mis...
