Fall of Berlin Wall

Ashley McCutcheon 2nd 10-27-12 The fall of the berlin wall as a turning point in history 1. â€Å"The Rise and Fall of the Berlin Wall (Part 2). † About. com 20th Century History. N. p. , n. d. Web. 28 Oct. 2012. . This article describes that the berlin wall was put up to divide between the west and east, which were democracy vs. communism at that point. Then later on the communist wanted a subtle change where as the german citizens did not agree, they wanted all of it ended.During 1988 and 1989 communism still weakened in Poland, Czechoslovakia and Hungary, then on the 9th of November in 1989, east german officials made a call to open the gates ultimately giving a sort of freedom to the people. 2. â€Å"Fall of Communism. † Fall of Communism. N. p. , n. d. Web. 28 Oct. 2012. . This article is helpful, because it explains an outcome of the berlin wall falling which was that communism also fell as resultant.Citizens gained power leading to reforms in the east and thus th e government decided to try different ways of ruling the people in order to make an attempt at saving communism. Eventually communism officially fell in 1991 when Gorbachev was forced to give power to Boris Yeltsin who diminished communism. 3. Goldenberg, Phyllis. â€Å"The Fall of the Berlin Wall: A Personal Account. † The Fall of the Berlin Wall. N. p. , 1994. Web. 27 Oct. 2012. . In this article, a personal account of how the event affected the people of berlin is presented. Phyllis Golden burg, a middle aged man living in Denmark, describes how him, among his friends and many others traveled from their homes to go see the Berlin wall after hearing of its supposed removal. The wall was being torn down by everyone and people were pouring through to the other side, a sort of revolution like no other could be.

Dynamometer

The wattmeter is an electrodynamic instrument for measuring the electric power or the supply rate of electrical energy of any given circuit. The device consists of a pair of fixed coils, known as current coils, and a movable coil known as the potential coil. The current coils are connected in series with the circuit, while the potential coil is connected in parallel. Also, on analog wattmeters, the potential coil carries a needle that moves over a scale to indicate the measurement. A current flowing through the current coil generates an electromagnetic field around the coil. The strength of this field is proportional to the line current and in phase with it. The potential coil has, as a general rule, a high-value resistor connected in series with it to reduce the current that flows through it. The result of this arrangement is that on a dc circuit, the deflection of the needle is proportional to both the current and the voltage, thus conforming to the equation W=VA or P=EI. On an ac circuit the deflection is proportional to the average instantaneous product of voltage and current, thus measuring true power, and possibly (depending on load characteristics) showing a different reading to that obtained by simply multiplying the readings showing on a stand-alone voltmeter and a stand-alone ammeter in the same circuit. The two circuits of a wattmeter are likely to be damaged by excessive current. The ammeter and voltmeter are both vulnerable to overheating – in case of an overload, their pointers will be driven off scale – but in the wattmeter, either or even both the current and potential circuits can overheat without the pointer approaching the end of the scale! This is because the position of the pointer depends on the power factor, voltage and current. Thus, a circuit with a low power factor will give a low reading on the wattmeter, even when both of its circuits are loaded to the maximum safety limit. Therefore, a wattmeter is rated not only in watts, but also in volts and amperes. Retrieved from â€Å"http://en. wikipedia. org/wiki/Wattmeter† (A dynamometer consists of an absorption (or absorber/driver) unit, and usually includes a means for measuring torque and rotational speed. An absorption unit consists of some type of rotor in a housing. The rotor is coupled to the engine or other equipment under test and is free to rotate at whatever speed is required for the test. Some means is provided to develop a braking torque between dynamometer's rotor and housing. The means for developing torque can be frictional, hydraulic, electromagnetic etc. according to the type of absorption/driver unit. One means for measuring torque is to mount the dynamometer housing so that is free to turn except that it is restrained by a torque arm. The housing can be made free to rotate by using trunnions connected to each end of the housing to support the dyno in pedestal mounted trunnion bearings. The torque arm is connected to the dyno housing and a weighing scales is positioned so that it measures the force exerted by the dyno housing in attempting to rotate. The torque is the force indicated by the scales multiplied by the length of the torque arm measured from the center of the dynamometer. A load cell transducer can be substituted for the scales in order to provide an electrical signal that is proportional to torque. Another means for measuring torque is to connect the engine to the dynamometer through a torque sensing coupling or torque transducer. A torque transducer provides an electrical signal that is proportional to torque. With electrical absorption units, it is possible to determine torque by measuring the current drawn (or generated) by the absorber/driver. This is generally a less accurate method, but it may be adequate for some purposes. A wide variety of tachometers are available for measuring speed. Some types can provide an electrical signal that is proportional to speed. When torque and speed signals are available, test data can be transmitted to a data acquisition system rather than being recorded manually. Speed and torque signals can also be recorded by a chart recorder or plotter. ) Power in an electric circuit is the product (multiplication) of voltage and current, so any meter designed to measure power must account for both of these variables. A special meter movement designed especially for power measurement is called the dynamometer movement, and is similar to a D'Arsonval or Weston movement in that a lightweight coil of wire is attached to the pointer mechanism. However, unlike the D'Arsonval or Weston movement, another (stationary) coil is used instead of a permanent magnet to provide the magnetic field for the moving coil to react against. The moving coil is generally energized by the voltage in the circuit, while the stationary coil is generally energized by the current in the circuit. A dynamometer movement connected in a circuit looks something like this: [pic] The top (horizontal) coil of wire measures load current while the bottom (vertical) coil measures load voltage. Just like the lightweight moving coils of voltmeter movements, the (moving) voltage coil of a dynamometer is typically connected in series with a range resistor so that full load voltage is not applied to it. Likewise, the (stationary) current coil of a dynamometer may have precision shunt resistors to divide the load current around it. With custom-built dynamometer movements, shunt resistors are less likely to be needed because the stationary coil can be constructed with as heavy of wire as needed without impacting meter response, unlike the moving coil which must be constructed of lightweight wire for minimum inertia.

Womens Place in Our Society

Today women are enjoying high place in our society because Islam has given them great respect. In the near past women were considered inferior to men. They were debarred from taking part in social life. Their sphere of activities was limited to domestic work. Up to the 19th century it was believed that women were the servants of the homes of their husbands. In those days women were not allowed to take part in political and social life and administration.Rousseau the French philosopher who never married once said The dignity of woman consists in being unknown to the world her glory is the esteem of her husband her pleasure the happiness of her family. Quite recently women have come to take more and more prominent part in many spheres of life In some respects they have excelled men. In sports intellectual and artist pursuits in office and industry they have set a new record of honesty and efficiency.They have succeeded marvelously as teachers and nurses goldsmith the famous poet and wr iter made a complaint two centuries ago Women famed of their valour their skill in politics or their learning have left the duties of their own sex in order to invade the privilege of ours. This is what the women are doing today. Now women are enjoying that place in society. Which they could never think of it past. There is particularly no field where women are not competing with men. In professions outdoor life and law they claim equality with men.In business trade industry in the learned professions in politics administration, scientific research literary and artistic activities. Eve is making herself felt everywhere. They are police and military officers. They are working as sale girls as air hostesses and as clerks and steno typists. They are turning out men from the posts of personal secretaries. As the days pass we have to get more and more used to the idea of seeing women working side by side of men riding driving, flying, playing even fighting. Even in Pakistan we have women athletes writers, leaders, administrators.They are fast discarding purdah and taking to active outdoor life. Law has given a woman a status equal to that of man. In nearly every democratic country women have the right to vote. Not only this now women got a chance to become the head of he state. The selection of Benazir Bhutto as Prime Minister twice in a great example of women's place in society. Many other women are also serving at key posts. Many thinkers including most of the Muslims do not like their idea of woman liking an active part in public life and in the professions.They argue that biologically woman's function is different from man's she has to be a mother. Women are not suitable for every job. They are too delicate to perform arduous duties of life. The real greatness of a woman lies in her role as mother. It is rightly said the hand that rocks the cradle rules the world. The mother who can bring up the right sort of children is really a great benefactor of society. Is lamic society gives a very respectable position to woman. The Holy Prophet has said â€Å"Verily the paradise lies under the feet of your mother†.

'One of the aims of EMU was that only the global balance of payments Essay

'One of the aims of EMU was that only the global balance of payments of the European Union with the rest of the world be of im - Essay Example In the recent economic epoch it is analyzed that the economic structure of different nations in the euro zone is actually separate. The monetary inflexibility of the policies in the EMU is becoming difficult when followed under the current economic operations of different nations. There is a widespread financial crisis in the European states (Kenen, 2000). The rigid policies of EMU prevent the monetary authorities in different countries to undergo the process of deficit financing that would help the nations to pay out its creditors. The EMU aims at evaluating the currencies of its European states and thus improving their Balance of Trade. It facilitates the nations to collect higher tax revenues and achieve a successful growth in their GDP (Visser, 2004). The essay tries to show how the EMU aims at improving the Balance of Payment (BOP) situation of Euro zone states with the rest of the world. The essay will try to analyze the optimal policy that can be adopted by the European Union to improve its balance of payments disequilibria with the rest of the world. Balance of Payment and its Significance The Balance of Payment helps to take an account of the monetary transactions carried out by a nation with the rest of the world (McCombie and Thirlwall, 1994). ... The current account looks into the trading affairs mainly of tangible goods and services; on the other hand the capital account looks into the inflow and outflow of financial assets in an economy. A nation can have either a fixed or a floating exchange rate. If a country has a fixed exchange rate then the central bank of the nation accepts foreign fund inflow exactly at par with the level of fund that the nation has out-flowed. By doing so the state makes the exchange rate of the economy rigid. The BoP surplus or deficit can only be analyzed in that situation by the reserves of foreign exchange with the central bank. On one other hand if the exchange rate of a country is more flexible than the central bank does not intervene in the matters of goods and service trading. In such situation, the country’s currency evaluates if its exports are more than its imports and the currency devaluates if the imports are more than the exports. The essay will throw a light on the BoP situatio ns of the almost all the states as a whole who are included in the Euro Zone. BoP Situations of Euro Zone The countries in the European Union are undergoing severe financial crisis since the latter half of 2009. The nations are not only facing a sovereign debt crisis but also a crisis in their banking affairs. The Euro Zone nations are lagging behind other nations both in terms of competitiveness and growth. In some of the countries the crisis was so severe that to refinance their state debts they had taken assistance from the third parties. The commercial banks in the Euro zone are undercapitalized (Baimbridge and Whyman, 2008). The configuration of the nations of the Euro zone countries as a monetary

Hong Kong and the Impact of Cyber Crimes Essay Example | Topics and Well Written Essays - 750 words

Hong Kong and the Impact of Cyber Crimes - Essay Example Nonetheless, no process is without a flaw; and many take advantage of this fact to steal from individuals and organizations that engage in e-payments. Despite all efforts of the government to restrain cyber crimes, and of information technology specialists to fortify domain firewalls, anxieties related to online transactions are mounting, and in a way, adversely affect international marketing endeavors. I. E-payment and Cybercrimes Electronic payments â€Å"refer to the systems and strategies required to enable the actual disbursement of funds electronically. It is concerned not only with the electronic transactions themselves, but also with the infrastructure required for billing and buyer authentication† (Botha and Geldenhuys, 2004, p. 67). The funds may be in the form of electronic checks, credit cards, purchasing cards, and electronic cash (Rainer and Cegielski, 2007). Authentication typically involves the username and password tandem, although other institutions support e xtended verification systems. For instance, Hong Kong and Shanghai Banking Corporation (HSBC) provide internet bankers with security device, while Emirates NBD incorporate the CHIP and PIN technology in all debit accounts. A team of researchers from Indiana University and Microsoft Corporation reported that major e-payment systems, e-retailers and e-commerce platforms have system security software glitches that can be abused by illicit websites to divert payments, or obtain goods for free or at reduced prices (Demery, 2011). Meanwhile, the Internet Fraud Complaint Center in the United States receives 200,000 consumer complaints per year, with securities and commodities fraud encompassing 16 percent (Miller and Jentz, 2009). Banks that rely heavily on online operations are at risk of losing profits as consumers also lose confidence on the security of online banking, specifically electronic payment of bills. Yet, although perpetrators of cyber crimes generally victimize financial serv ice companies, the Anti-Phishing Working Group has recorded cases of attempts to exploit â€Å"social networking and gambling sites† as well (CIO, 2007, p.36) II. Cyber Crimes in Hong Kong The Census and Statistics Department reveals that 76 percent of households in Hong Kong have computers, 73 percent of which maintains broadband connection; and about 63 percent of firms use personal computers, 98 percent of which do regular emails (Cagape, 2010). The figures clearly indicate that majority of the population in Hong Kong engage in online pursuits, and a significant portion of businesses are conducted via the internet. This alone leaves the country a viable target for cybercrimes. Speakers at the Information Security Summit 2008 reported an increase of 44 percent in hacking attacks in Hong Kong between January and October 2008, while the Computer Emergency Response Team (CERT) stated that during the same period, they have already dealt with 483 incidents of cyber crimes (Spam Fighter, 2008). Unfortunately, Hong Kong is also deficient in internet laws and certain websites are criticized for mediocre security features. Michelle Chan of Herbert Smith law firm observes that existing internet laws in Hong Kong are appropriate for misconducts in the early 1990s, but no further amendments were effected since then. On the other hand, this does not mean

Globalisation, International Trade and Marketing Essay

Globalisation, International Trade and Marketing - Essay Example Globalization trends have been different at various times of its evolution, allowing the observation of remarkable phases of evolution over time. The consideration of globalization process over the years, and the evaluation and assessment of the defining factors of globalization allow for the examination of past, present and future trends in globalization. Contemporary globalization takes a diverse and dynamic position, encompassing cultural, social, economic, political, technological and communication aspects. Origins of Contemporary Globalization Contemporary globalization is founded in human and social evolution, dating back to many centuries ago (Jain, 2011, p.10). The origin of modern time globalization can be traced by considering history of globalization throughout the years. The process can be said to have started right with the evolution of human societies. The multiplication and migration of human ancestors started between 10,000 and 20,000 years ago. At the time, hunting a nd gathering was the main survival practice. The multiplication of human life spread across the globe, aided by migration and settlement in new regions. Over the years to around 5,000 years ago, cultivation began and farming activities were evident in many natural environments around the world. Villages started developing and towns were being set up as a result. After the last ice age, agricultural revolution was experienced, marking a significant change in people’s life at the time (Jain, 2011, p.16). Need for exchange emerged, and trade resulted around 3,000 years ago. Tradable goods that included but not limited to artifacts and raw materials were exchanged. Global population growth was significantly rising, reaching one million people by this time. As a result, cultural, social and religious systems began to be realized. As high activity in all aspects of human life continued to be experienced, regional organizations were being realized. Growth and development of empires like Mesopotamia, Samarra, and Uruk emerged, and by 1AD, the entire world’s population approached 150 million people (Jain, 2011, p.19). With this increase in population, need for trade exacerbated. May social settings were not self-sufficient, leading to a scenario of interdependence among societies. Need for trade resulted in the establishment of trade routes around the world. 100 years after, major cities were emerging as trade centres, characterized by relatively high population in comparison to other settlement areas. Fifteenth Century marked a significant position for the current world phenomenon. This is the time that saw the development of the printing press in relatively developed societies of the world. A new world was therefore born, and global population hit 300 million people by this time. This and other major developmental aspects characterized the world until the 18th Century, when industrial revolution took place. Cultural, social, economic and political drive rs influenced the world, especially after the second revolution in agriculture. The global population was approaching a billion people. In the late 19th Century and early 20th Century (1880-1914), European empires had been fully integrated into the region’s set up, and world trade patterns were being re-organized and extended to integrate uncovered areas. By this time, the world population stood at approximately 1.6 billion people, with significant events in the 20th Century being World War I, Great

Titled Modern Portfolio Theory or Investment Management Essay

Titled Modern Portfolio Theory or Investment Management - Essay Example Thus, a portfolio may be defined as a combination of securities with varying risk and return characteristics which in turn contribute to the net worth of the investor. (Swisher, 2005) The topic of discussion in this paper is Modern Portfolio Theory or Investment Theory, which may be defined as the concepts that revolve around educating an investor regarding the steps that must be taken in order to develop a portfolio that will speak of rational choices and optimisation of financial resources. Before going any further, it is imperative to point out that investement brings a certain degree of speculation, especially in today's economic scenario where there has been a boom in the information transmission trends due to an increase in the number of people from various quarters flocking towards investing in portfolios. This paper will endeavor to study modern portfolio theory (MPT), in terms of its various elements like Markowitz diversification, the efficient frontier as well as concepts like the Capital Asset Pricing Model, better known as CAPM. The tools used in the course of application of these concepts include the Capital Market Line and the Security Market Line apart from alpha and beta coefficients which help measure mean, variance, risk and returns of the portfolio as a whole. To begin with, the paper will introduce the Modern Portfolio Theory as propounded by Harry Markowitz in the early 1950s, before moving on towards defining the elements like beta, risk and return that are concerned with the various concepts of Modern Portfolio like diversification and Capital Asset Pricing Model or CAPM. (Swisher, 2005) The intorduction of the key elements before discussing and analysing the actual concepts has been carried out so as to ensure that there is full understanding of the tools that will be used in the study of the Modern Portfolio Theory. The paper will progress through a series of headings that are relevant to introduce new topics. These topics are linked with each other through the tools like beta, risk, return, mean and variance, among others. There will illustrations in terms of formulae and diagrams for all sections of the paper. Markowitz and Modern Portfolio Theory Modern Portfolio Theory has come up a practical model for the measurement of the various trends affecting the portfolio market. As a body of concepts and tools, it is concerned with the identification of markets that have high return potential and those which have a heavy risk factor, so as to help the investor choose more wisely. At the same time, the modern portfolio theory also brings us face to face with the fact that it is equally concerned with varying combinations of assets to zero in on the favourable markets and customers. (Markowitz, 1952) Born in the year 1952, the modern portfolio theory was the brainchild of Harry Markowitz who recognised the need for a certain set of parameters within which the obvious diversification trends may be
