Strategic theory - Research Paper Example It is many peopleÃ¢â¬â¢s beliefs that history has provided strategic thinkers with universal principles for the conduct of war. This essay is going to discuss how history provided military strategic thinkers (Napoleon and Carl von Clausewitz) with universal principles for the conduct of war (Buchan 92). The historically known Principles of War, Sun Tzu documented were influential to strategic thinkers of the Wars. There is a belief that, history provided strategic thinkers such as Napoleon and Carl von Clausewitz with universal principles for the conduct of war (Mahnken 29). There are no approved principals of War, although a number of strategic thinkers have their own principles (Cimbala 26). The War principles, which Carl von Clausewitz identified in his essay Ã¢â¬Å"Principles of WarÃ¢â¬ and thereafter discussed in his book, about war were influential to military thinkers of the North Atlantic region. Military strategy is a set of ideas, which military organizations implement ed to achieve desired strategic goals. Founded from Greek strategies, military strategy during its first appearance in the 18thcentury was termed in its sense as the Ã¢â¬Å"general artÃ¢â¬ and Ã¢â¬Å"arrangement artÃ¢â¬ of military troops (Buchan 72). ... definition, which had less emphasis on battles, explaining military strategy as Ã¢â¬Å"the art of applying and distributing military means to achieve and fulfill policy ends (Cimbala 31). Hence, the two strategic thinkers gave the supremacy to aims of politics over military objectives. Military strategy was among the Ã¢â¬Å"artsÃ¢â¬ and Ã¢â¬Å"sciencesÃ¢â¬ trivium that governed how to conduct warfare, and the rest were tactics, the maneuvering forces, and execution of plans in battle, maintenance, and logistics of an army During the 19th century,. This view prevailed since the time of Roman, and the boundary between tactics and strategy during this century was blurred, and in some times, the categorization of a verdict was a matter of personal opinion. Tactics and strategy are almost related and are on similar range, modern thinking puts the level of operation between strategy and tactics (Cimbala 33). All deal with time, distance, and force although the strategy has large scal e, endures for many years, and is societal. On the other hand, tactics have small scale and engage the disposition of less elements lasting for only few hours or weeks. Historically, people understood strategy as governing the prelude to military battle while, on the other hand, tactics governed its execution. However, during the twentieth century world war, the distinction between battle and maneuver, tactics and strategy, expanded due to the advancement of transit and technology (Cimbala 35). Most people hold the belief that, this military strategy history really provided strategic thinkers such as Napoleon and Clausewitz with universal principals on how to conduct wars. History has a lot of guidance on how to plan and conduct military wars, whereby most of strategy thinkers rely on (Collins 59). For

Economic Distribution in the U.S. ,Why The Rich get richer - Term Paper Example This brings us to the basic question, and incidentally the title of this essay, why the rich get Richer? This paper strives to offer a basic understanding of the economic distribution of income and wealth in America and the reasons for such discrepancies, which further widen the gap between the rich and the poor, making the rich Ã¢â¬â richer in the process and at the same time, pushing the poor towards stark poverty. During the early 1980s era, several economists as well as researchers initiated reports concerning the average wages of American workers, and pointed out the fact that their wages were stagnant ever since the early 1970s and that the allocation of their earnings was, in fact, becoming more and more unequal, thereby widening the gap between the rich and the poor. Several explanations and suggestions were offered for such an occurrence. However one of the most significant of them was that the reason behind such a turn of events was the unemployment reallocation in the industrial composition of the country or the deindustrialization of the United States away from manufacturing industries to service oriented ones. It was believed that the average earnings of the workers in the service industry were relatively lower than that in the manufacturing industry. The repercussion of such a transformation with respect to the breadwinners belonging to the Ã¢â¬Ëmiddle Ã¢â¬â classÃ¢â¬â¢ hous eholds was evident, and the news of the steadily deteriorating American middle class, made headlines across the nation creating a great furore. Further apprehensions over mounting income disparity surfaced in the mid - 1980s with the publication of several books, reports and researches on the topic, which fuelled the anxiety that Americans were now facing an escalating disproportion of outlooks in accomplishing a stable middle class existence. The Economist stated that the gap between the rich and the poor is larger in the United States as

The resistance of the wire Essay The atoms take up more space so there is more chance of the electrons being caught by them; more energy is going to be lost as heat. As temperature increases so does resistance. If we increase the cross section there will be a bigger area, so more free electrons available for conduction. More free electrons means a larger current so a better conductor, meaning lower resistance. Materials should effect resistance also because different materials have different amounts of free electrons. The more free electrons means better conductor so lower resistance. Resistance of different materials will vary. I predict that from my experiment my graph will have a straight diaganol line like this. Planning As we increase the length of the wire we will be measuring the voltage when the current is at 1amp. Using these results we will work out the resistance. We do this because we need to find out if the length of a wire effects the resistance of the wire. And from these results find out how we can reduce the resistance of the wire. When measuring we will have to be accurate and make sure that the crocodile clips on the wire are exactly in line with the right measurements. Even 1mm can change the results dramatically. We will also have to ensure that the wire is pulled taught because if its bent up a bit its not stretched out to its full length so are measurements will be wrong and could effect the experiment. We will also make sure that the current does not go over 1-amp. Because the prelim work showed us that after this amount the test will be unfair, and it will be impossible to ensure the results are valid. Because the sellotape melts, and the wire expands and looses shape. In order to get accurate results we will do three repeats of the experiment. Are results are more reliable then because we have three to look at so we know what the measurements should roughly be around and any major errors will stand out. Analysis From doing my experiment and looking at my results I found out that as the length of the wire increases, the resistance increases. This shows that my predictions were accurate as this is what I predicted. From looking at the graph I also notice that it is a straight diagonal line, which is how I predicted it to be. This shows it is directly proportional. As the length of the wire doubles there is double the chance that the electrons will get captured by the metal atoms. Therefore double the resistance. Double length=double resistance 10 20 30 40 50 60 70 80 90 100 gradient = up = ? across cm Evaluation I think my experiment worked well because my results were as I predicted them to be and I did a fair test. Also there wasnt any major errors. From looking at my graph I can see it is a straight diaganol line just as I predicted. This shows it is directly proportional. To imrove my experiment and get more accurate results I could nail or solder the wire down to the ruler. This way it is more secure than the sellotape and it cant move out of position. Instead of using crocodile clips, as these could put a kink in the wire. I could use a knife edge or something metal to just touch the wire, as this is a conductor so still allows a current to flow through. I think I have enough results to be sure of what I wrote in my conclusion. I think this because my results prove the theory as length increases resistance increases.

Biometrics: The Science of Human Recognition As our society becomes more and more modernized so does our need for more sophisticated ways to identify people for who they really are. Biometrics is the science of human recognition. With this rapid movement to develop this new technology, many companies have come out with different ways to distinguish people. Some of these new forms of recognition include; retinal scanning, iris recognition, finger imaging, hand geometry, face recognition, voice recognition and signature recognition. These forms of distinguish people may be broken down into two basic categories: physical characteristics and personal traits. Physical characteristics are specific to each person. A physical characteristic is as unique as a personÃ¢â¬â¢s DNA code. A personal trait is a Ã¢â¬ËstyleÃ¢â¬â¢ that is often unique to each person. The only problem with the recognition of this Ã¢â¬ËstyleÃ¢â¬â¢ is that it may often change as a person grows and matures. Retinal scanning falls into the category of scanning for physical characteristics. It is performed by bouncing a laser beam off the cornea, which then absorbs specific frequencies of light according to that personÃ¢â¬â¢s specific cornea. The light that is not absorbed bounces back into the machine and is then read. The machine is able to recognize the unabsorbed frequencies of light as, Frank Turco. Another new physical biometrics system is iris recognition. Iris recognition is similar to retinal scanning. The colored area of the eye that surrounds the pupil has many lines randomly placed. These lines are specific to each individual; like a barcode is to a product. Again, a laser scans the eye and recognizes the bars of the iris as a person. Amazing isnÃ¢â¬â¢t it? Iris canning tends to be more Ã¢â¬Ëuser friendlyÃ¢â¬â¢ because you donÃ¢â¬â¢t need to be as close to the machine when it is scanning your iris. You may be up to nine inches away, where as with retinal scanning you may only be one to two inches away. The reason iris scanning is more "user friendly" is because when utilized by the public many communicable diseases may be passes along by the machine because of it close contact with the person. Face recognition is similar to the way we recognize people. A computer would be utilized to take a photo of each person and then analyze it. The computer's analysis of the photo would use facial geometry to recognize each person.

8. How can the dream at the end of the story be related to the major incidents that precede it? The dream at the end of the story is about the circus with his grandfather. He refused to laugh at the clowns no matter what they did. There is a relationship between clowns at circus and the black boy in battle royal. They are forced to entertain the white man and are treated as if they are no better than animal. The seemingly endless series of envelopes implies that inequality still continue for a long time until black man fall of weariness and white society will continue to create clowns for their entertainment. 9. Given the grandfatherÃ¢â¬â¢s advice, explain how Ã¢â¬Å"meeknessÃ¢â¬ can be a Ã¢â¬Å"dangerous activityÃ¢â¬ and a weapon against oppression. In the death bed the grandfather told his son as well as his grandson keep up a good fight. Ã¢â¬Å"Live with your head in the lionÃ¢â¬â¢s mouthÃ¢â¬ , the grandfather want his son to prepare for himself a mask of meekness, overcome white persons with yeses, underline them with grins, agree them to death and destruction. This meekness is considered as dangerous activity because their family as well as many black men in recent society is controlled and oppressed by the white man. Becoming the whiteÃ¢â¬â¢s favorite is the only way to survive. However meekness is not the same as surrender, it seems to be a shield to conceal a deeper revolutionary spirit. The grandfather bequeathed to his grandson not only strategy to live with Ã¢â¬Å"the lionÃ¢â¬ but also a weapon against oppression.

OLED stands for organic light-emitting diode and its cutting edge technology results from many innovations in display monitors, lighting, and more. As the name suggests, OLED technology is the next-generation advance of regular LEDs and LCDs, or liquid crystal displays. LED Displays Closely related LED displays were first introduced to consumers in 2009. LED television sets were much thinner and brighter than their predecessors: plasmas, LCD HDTVs, and, of course, the humongous and outdated CRTs, or cathode-ray tube displays. OLED displays were introduced commercially a year later, and allow for even thinner, brighter, and crisper displays than LED. With OLED technology, completely flexible screens that can fold or roll up are possible. Lighting OLED technology is exciting because it is a viable and functional innovation in lighting. A lot of OLED products are light panels whose large areas diffuse lighting, but the technology lends itself well to different applications like the ability to change shape, colors, and transparency. Other benefits of OLED lighting compared to traditional alternatives includes energy efficiency, and the lack of poisonous mercury. In 2009, Philips became the first company to manufacture an OLED lighting panel called Lumiblade. Philips described the potential of their Lumiblade as thin (less than 2 mm thick) and flat, and with little heat dissipation, Lumiblade can be embedded into most materials with ease. It gives designers almost limitless scope to mold and meld Lumiblade into everyday objects, scenes and surfaces, from chairs and clothing to walls, windows and tabletops. In 2013, Philips and BASF combined efforts to invent a lighted transparent car roof. It will be solar powered, and will turn transparent when switched off. Thats just one of many revolutionary developments possible with such state-of-the-art-tech. Mechanical Functions and Processes In the simplest of terms, OLEDs are made from organic semiconductor materials that emit light when an electrical current is applied. OLEDs works by passing electricity through one or more incredibly thin layers of organic semiconductors. These layers are sandwiched between two charged electrodesÃ¢â¬âone positive and one negative. The Ã¢â¬Å"sandwichÃ¢â¬ is placed on a sheet of glass or other transparent material which, in technical terms, is called a Ã¢â¬Å"substrateÃ¢â¬ . When current is applied to the electrodes, they emit positively and negatively charged holes and electrons. These combine in the middle layer of the sandwich to create a brief, high-energy state called Ã¢â¬Å"excitationÃ¢â¬ . As this layer returns to its original, stable, Ã¢â¬Å"non-excitedÃ¢â¬ state, the energy flows evenly through the organic film, causing it to emit light. History OLED diode technology was invented by researchers at the Eastman Kodak company in 1987. Chemists Ching W. Tang and Steven Van Slyke were the principal inventors. In June 2001, Van Slyke and Tang received an Industrial Innovation Award from the American Chemical Society for their work with organic light-emitting diodes. Kodak released several of the earliest OLED-equipped products, including the first digital camera with a 2.2-inch OLED display with 512 by 218 pixels, the EasyShare LS633, in 2003. Kodak has since licensed its OLED technology to many companies, and they are still researching OLED light technology, display technology, and other projects. In the early 2000s, researchers at Pacific Northwest National Laboratory and the Department of Energy invented two technologies necessary to make flexible OLEDs. First, Flexible Glass an engineered substrate that provides a flexible surface, and second, a Barix thin film coating that protects a flexible display from harmful air and moisture.

For many years, when middle and high school English teachers would ask me to recommend a good book for teaching grammar, Id direct them to Constance Weavers Teaching Grammar in Context (Heinemann, 1996). Based on sound research and extensive road testing, Weavers book views grammar as a positive activity for making meaning, not just an exercise in tracking down Ã¢â¬â¹errors or labeling parts of speech. But Ive stopped recommending Teaching Grammar in Context, though its still in print. Now I encourage teachers to pick up a copy of Weavers more recent book, Grammar to Enrich and Enhance Writing (Heinemann, 2008). Assisted by her colleague Jonathan Bush, Dr. Weaver does more than simply rework the concepts introduced in her earlier study. She delivers on her promise to offer a text thats more comprehensive, more reader-friendly, and more concretely focused on teachers practical needs. The fastest way to help you decide whether youd get along with Dr. Weaver, theoretically speaking, is to reprint her 12 principles for teaching grammar to enrich and enhance writing--principles that underlie all the varied activities in her book. Teaching grammar divorced from writing doesnt strengthen writing and therefore wastes time.Few grammatical terms are actually needed to discuss writing.Sophisticated grammar is fostered in literacy-rich and language-rich environments.Grammar instruction for writing should build upon students developmental readiness.Grammar options are best expanded through reading and in conjunction with writing.Grammar conventions taught in isolation seldom transfer to writing.Marking corrections on students papers does little good.Grammar conventions are applied most readily when taught in conjunction with editing.Instruction in conventional editing is important for all students but must honor their home language or dialect.Progress may involve new kinds of errors as students try to apply new writing skills.Grammar instruction should be included during various phases of writing.More research is needed on effective ways of teaching grammar to strengthen writing.
