Using Newton Method of Optimization Coursework Example | Topics and Well Written Essays - 250 words - 1

Using Newton Method of Optimization - Coursework Example On the other hand, if a constrained optimization is done (for example, with Lagrange multipliers), the problem may become one of saddle point finding, in which case the Hessian will be symmetric indefinite and the solution of xn+1 will need to be done with a method that will work for such, such as the LDLT variant of Cholesky factorization or the conjugate residual method. There also exist various quasi-Newton methods, where an approximation for the Hessian (or its inverse directly) is built up from changes in the gradient. If the Hessian is close to a non-invertible matrix, the inverted Hessian can be numerically unstable and the solution may diverge. In this case, certain workarounds have been tried in the past, which have varied success with certain problems. One can, for example, modify the Hessian by adding a correction matrix Bn so as to make Hf(in) + Bn positive definite. One approach is to diagonalize H f(xn) and choose Bn so that H f(xn) + Bn has the same eigenvectors as H f(xn), but with each negative eigenvalue replaced by Ï µ > 0.

The Fashion Industry - Zara Coursework Example | Topics and Well Written Essays - 2500 words

The Fashion Industry - Zara - Coursework Example The paper "The Fashion Industry - Zara" will look into the marketing environment of Zara. The fashion industry is greatly effectually by the political variable that’s are present in different nations. According to Holmquist (2003), there is certain liberty when it comes to the quantity of material import related to the fashion industry. This is a positive approach for them, especially in the Euro zone. Zara creates very good social connections and is also involved in CSR activities that has helped Zara a good brand name in the global political environment. The government is involved in the changes that affects the environment at large. The fashion industry is rapidly changing with the several trends that keeps on changing from a day to day basis. However, they also involve a lot of environmental wastage (Allen, 2013). According to Allen (2013), that the per capita income or in other words the GDP is also an important decision making factor for the fashion industry. UK in this case, has a strong GDP and that is why all the companies are concentrating on entering the UK market. However, there are different market where many people also prefer to buy cheap apparels. The economy of Europe is rising gradually and that is why the future is bright for the fashion and retail industry especially because the rise in the disposable income in the general public, gives them the opportunity to buy the fashionable clothes to stay with the current trend of the market. From the point of view of the currency.

War Essay -- essays research papers

The first issue to be considered is what is war and what is its definition. The student of war needs to be careful in examining definitions of war, for like any social phenomena, definitions are varied, and often the proposed definition masks a particular political or philosophical stance paraded by the author. This is as true of dictionary definitions as well as of articles on military or political history. Cicero defines war broadly as "a contention by force"; Hugo Grotius adds that "war is the state of contending parties, considered as such"; Thomas Hobbes notes that war is also an attitude: "By war is meant a state of affairs, which may exist even while its operations are not continued"; Denis Diderot comments that war is "a convulsive and violent disease of the body politic;" for Karl von Clausewitz, "war is the continuation of politics by other means", and so on. Each definition has its strengths and weaknesses, but often is the culmination of the writer's broader philosophical positions. For example, the notion that wars only involve states-as Clausewitz implies-belies a strong political theory that assumes politics can only involve states and that war is in some manner or form a reflection of political activity. 'War' defined by Webster's Dictionary is a state of open and declared, hostile armed conflict between states or nations, or a period of such conflict. This captures a particularly political-rationalistic account of war and warfare, i.e., that war needs to be explicitly declared and to be between states to be a war. We find Rousseau arguing this position: "War is constituted by a relation between things, and not between persons†¦War then is a relation, not between man and man, but between State and State†¦" (The Social Contract). The military historian, John Keegan offers a useful characterization of the political-rationalist theory of war in his A History of War. It is assumed to be an orderly affair in which states are involved, in which there are declared beginnings and expected ends, easily identifiable combatants, and high levels of obedience by subordinates. The form of rational war is narrowly defined, as distinguished by the expectation of sieges, pitched battles, skirmishes, raids, reconnaissance, patrol and outpost duties, with each possessing their own conventions. As ... ...ine war not just as a conflict between states (i.e., the rationalist position), but also a conflict between non-state peoples, non-declared actions, and highly organized, politically controlled wars as well as culturally evolved, ritualistic wars and guerrilla uprisings, that appear to have no centrally controlling body and may perhaps be described as emerging spontaneously. The political issue of defining war poses the first philosophical problem, but once that is acknowledged, a definition that captures the clash of arms, the state of mutual tension and threat of violence between groups, the authorized declaration by a sovereign body, and so on can be drawn upon to distinguish wars from riots and rebellions, collective violence from personal violence, metaphorical clashes of values from actual or threatened clashes of arms. Back to Table of Contents 2. What causes war? Various sub-disciplines have grappled with war's etiology, but each in turn, as with definitions of war, often reflects a tacit or explicit acceptance of broader philosophical issues on the nature of determinism and freedom. For example, if it is claimed that man is not free to choose his actions (strong

Dan Brown’s Deception Point Review

Unless you live in a cave (I’m not judging) then you’ve probably heard of Dan Brown. If you haven’t heard of Dan Brown then you’ve probably heard of â€Å"The Da Vinci Code†. If you’ve heard of neither then I suggest you watch less TV and stop collecting porn from the internet. (I’m still not judging). I won’t blog on about how fantastic the Da Vince Code is (it really is) or how mind-blowing the concepts where (they really were) or offer my thoughts on the validity of Dan Brown’s research for the book (not enough time in the day). Nope. This is about one of his earlier novels: Deception Point.If you’ve not read it, then stop reading this puerile obfuscation of the written language (that’s this blog by the way) and go read it now. If you need a little tease (still not judging) then reads on†¦. (Please affect your best â€Å"Deep Movie Trailer Voice†). There are no direct spoilers here, but if you prefer not to know anything about this book, turn away now. Not looking at your computer screen now? That’s a bit silly. President Zach Herney is in trouble. He’s taking a beating in the polls for the forthcoming presidential election. A stoic supporter of NASA, he’s backed and funded from tax payers money a string of expensive NASA blunders.His rival, the ruthless Senator Sedgewick Sexton, is riding a wave of unrest from the American people he’s stirred by condemning the billions of tax payers money that’s been wasted on failed NASA projects and he’s all but guaranteed the presidency. As the situation gets even more desperate for the President, a new NASA satellite detects evidence of an astonishing object buried deep in the Arctic ice: a meteorite containing the fossilized remains of extra terrestrial life. The floundering space agency appears to have struck gold and will silence all their critics with their find.The President dispatches Senator Sexton’s daughter, NRO intelligence analyst Rachel to the Arctic to verify the find. She’s accompanied by a team of NASA and civilian experts, including the charismatic â€Å"Amazing Seas† presenter Michael Tolland. Their every move is watched by the mysterious Delta Force taking orders from â€Å"the controller†. However, things start to unravel quickly when Rachel uncovers that the object isn’t all that it appears to be. A shocking discovery that will plunge the country into controversy. Before Rachel can make her findings known she realizes that her discovery puts her life, and the lives of others in danger.Fleeing for her life with Michael Tolland and Corky Marlinson – a NASA scientist – in the dangerous Arctic conditions they have only one hope for survival: to find out who’s behind the deception. Back in Washington, the election grows closer and the stakes get higher. William Pickering, the NRO director is frustra ted with NASA’s regular security leaks which put their technological advances into the hands of the highest bidder. The NASA administrator, an ex-Pentagon man is fighting to keep NASA from being restructured as part of the governments intelligence community joining the FBI and the CIA.The President, taking advice from his sly senior advisor Marjorie Tench, prepares to tell the world of NASA’s discovery. Sounds good, doesn’t it? It is. Dan Brown has really done is research and although you’re entertained, you also learn a fair bit about the Arctic, meteorites and fossils. His technical detail is on par with Tom Clancy although it’s not as dry as some of Clancy’s work. His real flair is in involving the reader. This is a book that you won’t want to put down. Now, go read it.

The Birthplace Of A Nation - 1180 Words

The Birthplace of a Nation Walking along an old dirt road that was once, in days gone by, a trade route used by Native Americans, my attention is drawn to a simple, little building in the middle of a peaceful field. I can hear the sweet mockingbird’s song, insects buzzing, the odd acorn falling from a tree and hitting the ground with a soft thud, and a gentle rustling of the leaves as the breeze blows through the magnolia trees. To imagine what took place here nearly two hundred years ago is truly a spectacular experience! Who would have thought that a cabin once designed to be a modest mercantile would be miraculously transformed into a symbol of freedom and an inspiration of courage? Rich in history, a symbol of the heritage of Texas, the birthplace of a nation—this is â€Å"Independence Hall.† Independence Hall is a humble, one-room, wooden cabin located at the Washington on the Brazos Historic Site in Texas. At first glance, this modest place may not appear significant, after all, it was designed to be a practical, little mercantile. But this place is so much more than a mercantile: it is a symbol of a heritage that belongs to all Texans today as well as to all lovers of freedom and truth. It was late fall in the year 1835 when unrest began brewing in the hearts of many Texans in what was then a part of Mexico. These Texans felt that Mexico had not kept her word regarding the individual rights of her citizens. With the Alamo being under attack by the Mexican army, andShow MoreRelatedThe Birthplace Of A Nation Essay1269 Words   |  6 PagesThe Birthplace of a Nation A place saturated with history, a symbol of the rich heritage of Texas, the birthplace of a nation—this is â€Å"Independence Hall.† Independence Hall is a little wood building located at the Washington on the Brazos Historic Site in Texas.

Private Security vs. Law Enforcement Matrix Summary

Private Security versus Law Enforcement: Matrix Summary Private security and public law enforcement share many of the same goals: preventing crime and disorder, identifying criminals, and ensuring the security of people and property, (Private Security and Public Law Enforcement, n.d.). There are many more private security officers than public police officers, making tandem projects and collaboration essential (Private Security and Public Law Enforcement, n.d.). There may be some overlap between public law enforcement and private security, but generally the latter can be more highly specialized and are therefore useful in situations such as campus security. Large privately owned facilities like the campus stadium require a dedicated staff of personnel, rather than a sporadic or incident response team. Therefore, security at the stadium during games can be best provided by the private sector. The public law enforcement agencies in the community can and should be alerted as to when games are being attended so that they can provide back-up support or ancillary services when required. Some of the distinct advantages to employing an effective private security force at campus games include the following. First, the security officers will be specialized in dealing with the sporting events. Second, they operate with fewer restrictions but with greater focus (Adam, n.d.). The potential drawbacks to using a private security force at the stadium include the need for cohesiveShow MoreRelatedCloud Computing Security67046 Words   |  269 PagesSECURITY GUIDANCE FOR CRITICAL AREAS OF FOCUS IN CLOUD COMPUTING V3.0 SECURITY GUIDANCE FOR CRITICAL AREAS OF FOCUS IN CLOUD COMPUTING V3.0 INTRODUCTION The guidance provided herein is the third version of the Cloud Security Alliance document, â€Å"Security Guidance for Critical Areas of Focus in Cloud Computing,† which was originally released in April 2009.

Abnormal Psychology - Film Review - Mental Disorders in...

Section A When we first meet Jack we learn that that he is a 30year old single white male complaining of insomnia for over 6 months. His job is a liability consultant for an automotive company that requires him to take frequent trips to different time zones which often leave him jet lagged. He goes to the doctor to get a prescription to help him sleep, but the doctor prescribes support groups for cancer patients, so that Jack could see what real suffering was. During one of his business trips he meets Tyler Durden, a nihilist soap salesman who is disgruntled with common culture. Eventually in the movie Tyler takes the fight club and turns it into Project Mayhem, which organizes increasingly serious anti-capitalism vandalism ventures.†¦show more content†¦Jack/Tyler’s struggle is one to make his own decisions, but since the particular brand of Dissociative Identity Disorder from which I believe he is suffering from, explicitly contains an element of dominant/submissive character type to it; and it is very clear that Jack isn’t making his own decisions even when he is Jack. Tyler’s key characteristic is that he attempts not only to create his own environment but forces others to accept it. Section B My official diagnosis of Jack/Tyler is Dissociative Identity Disorder, also known as DID. DID is formally known as Multiple Personality Disorder, where the patients have the presence of two or more distinct identities/personality states that recurrently take control of the person’s behavior. Jack had no idea he was Tyler, and there is very little evidence until the end that Tyler knows he is Jack. Usually it is said that personalities are vastly different, and after watching the movie it is clear that Tyler and Jack are completely opposite to one another. Dissociative Identity Disorder patients can’t integrate these various aspects of their identity, memory, consciousness without professional help. Each personality, or alter ego, has its own history, name and image. According to research it is said that the primary identity, which in the case of this movie is Jack is passive, dependent, guilty and depressed.
