Computer technology and the networked organization Essay
Computer technology and the networked organization - Essay Example This helps one monitor the network properly. Any failure is easily seen and will not affect the entire organisation of the company. Star topology is reliable because it is easy to back up the data and easy to access the data. Another important reason is that in this topology my companies system will have no disruptions to the network when connecting and removing devices. Under the architecture the configurations of the company peer to peer networking architecture will be put in place. This will be of help because all the computers in the network will have the same privilege, capabilities and responsibility among themselves. This will enable file sharing and if anyone wants to acquire information from another customer then he will do it fast and also it is hard for the system to collapse because all computers depend from each other not like client server where one computer is expected for file sharing. The communication protocol used will be TCP/IP because it will enable the computers in the network to communicate without the help of central management. The reason why I will use TCP/IP in my company because it is compatible with various types of computer hardware and network configurations. Another reason why I found it relevant is it routable and so finds the most efficient path for the packets to move across the network. I would have created a firewall that will not allow the people who are not in the network to get access in it. This implies that it will set up a control of the incoming and outgoing network traffic by analysing the data packets and determining whether it should pass or not. Secondly I will train my personnel and enforce a policy.by having employees and customers who understand and adhere to the companiesââ¬â¢ security policies will enable reduce security problems. I will create strong security passwords and strong forms of authentication to prevent guessing and cracking. Thirdly I will uses security

Stress Effects and Ways to Reduce Stress Essay Example | Topics and Well Written Essays - 1250 words
Stress Effects and Ways to Reduce Stress - Essay Example However, there are number of causes of stress. Like emotional stress, physical stress, environmental stresses, energetic and health stress. Physical stress occurs due to over physical work/activity and it is very common in adults. Most importantly, physical stress effects regularly on many body joints changes and will create pain in your later life. Stress can affect you in the two ways; long term and short term. Long term stress is much worst than short term; Moreover; long term stress is more dangerous because it creates regular changes in your body in many ways. In general term, there are there broad sectors of stress effects. From the medical point of view, the physiological stress if activate in your brain, it will triggers the pituitary gland and sympathetic nervous system as a result of its activation - it creates regular changes in your adrenal gland which raises your heart rates. Furthermore, human liver produces energy throughout the stress situation and in the process, the patient can suffer stomach pain, constipation and so forth. The physiological stress raises your heart beats up to 71 to 90 beats in a minute to 200 per minute. Yes, Stress effects emotiona... In general term, there are there broad sectors of stress effects. 1) Physiological Effects From the medical point of view, the physiological stress if activate in your brain, it will triggers the pituitary gland and sympathetic nervous system as a result of its activation - it creates regular changes in your adrenal gland which raises your heart rates. Furthermore, human liver produces energy throughout the stress situation and in the process, the patient can suffer stomach pain, constipation and so forth. The physiological stress raises your heart beats up to 71 to 90 beats in a minute to 200 per minute. Emotional Effects Yes, Stress effects emotionally as well and if it affects emotionally, it can create sound changes in your brain function. As a result of its activation, it adversely affects your mental capabilities, - your logical thinking becomes illogical, and you become anxious for no reason. However, it can be minor or major, major stress could lead you to a suicide. Besides this, it alters your behavioral patterns suddenly in these feelings; you become very sensitive and can be very irritating. You could enter into an argument with others for no reason; whatsoever, you can suddenly starting fighting with others at work. It may turn your mind on pessimistic thinking on all aspects, by and large behavioral changes adversely affect decision making powers either at work or at home concerns. Also, you could become gloomy and it makes you less tolerant.

Main advantages of unstructured methods
Main advantages of unstructured methods Unstructured method This method makes use of a rational compilation of elements to load up the domain, because the engagements of elements have no visible pattern, the mesh is called unstructured. This type of grids in general makes use of triangles in 2D and tetrahedral in 3D. With structured method, the elements are capable of twisted and stretched to well the domain. This method has the skill to be automated to a large degree. Known good CAD model, a good meshing student or person can without human intervention place triangles on the surface and tetrahedral in the volume with very small effort from the user. The automatic meshing algorithm characteristically involves meshing the boundary and then also adding elements touching the boundary or adding points in the interior and reconnecting the Delaunay elements. Main advantage of unstructured method Advantages of unstructured method is with the aim of they are very programmed and, as a result, require small user time effort but the user no need to worry about lay out block structure or relations. In addition the unstructured methods are well suitable to inexperienced users because they require small user input and will generate a suitable mesh under most circumstances. Unstructured method and its applications Triangle mesh generator makes use of 2D problems, and it produces an unstructured triangular mesh. Tetrahedral meshing is appropriate for uses in viscous flow simulations are wished-for. The approach which is chase consists of the initial generation of a number of unstructured layers of highly rigid elements Structured method This method of mesh generation starts with basic geometry and tensor analysis previous to moving on to identify the variety of approaches that can be employed in the generation of structured meshing. In addition structured method makes use of quadrilateral elements in 2D and hexahedral elements in 3D in a computational rectangular selection. Main advantage of structured method Advantages of structured mesh method is their simplicity, ease of use code and is suitable for multi-mesh, it is very complicated to generate a structured mesh for complex construction of body, such as a complete aircraft. Structured method and its applications Structured mesh, in particular multi-block structured mesh, is one of the main productions CFD tools. Multi-block means that the block topology can be from multiply connected blocks and each block is composed of 3D hexahedral, 2D quadrilateral and 1D linear or quadratic element set up in rows and columns, but this blocks can be removed, deleted or glued to others parts and also the multi-block structured mesh gives CFD user more control over the design of their meshing and make sure that quality is maintained all the way through their design and achieves the results. Multi-block topology A multi-block topology is used to build a meshing for the same geometry and this mesh is build in 6 blocks and deleting the top 2 corner blocks to complete a meshing with right aspect ratio. Hybrid method Hybrid mesh method is designed to obtain advantage of the positive aspects of both unstructured and structured mesh. Hybrid mesh makes use of some form of structured mesh in local regions while using unstructured mesh in the size of the domain. In addition the hybrid mesh contain tetrahedral, hexahedral and pyramid elements in 3D and quadrilaterals in 2D. But hexahedral elements are excellent close to solid boundaries and can afford the user of CFD a high degree of control. Main advantage and disadvantage of hybrid method Hybrid mesh advantages method is when we can make use of the positive properties of structured mesh elements in the regions which require them the most and use automatic unstructured mesh techniques where is not much happen in the flow field. Prismatic or hexahedral layers close to wall surfaces show good clustering capability characteristic of structured meshing approaches. Another advantage is that the use of tetrahedral mesh to fill the rest of the domain permit single-block generation for particularly complex geometries since the tetrahedral is the simplex element in 3D. Hybrid mesh disadvantage method is difficult to use and involve user of CFD expertise in put out the various structured mesh properties and locations to obtain the best results. The hybrid method is less strong the unstructured mesh methods. Hybrid method and its applications Hybrid method, in particular prismatic mesh generation makes use of the visibility condition, namely, the node normal vector is able to be seen from all the triangles sharing the node. A simple and general method is included to treat walls, concaves and narrow gaps. Tetrahedral and pyramids are integrated naturally by treating them as exceptional cases of prismatic cells and the methods is successfully applied for a entire aircraft configuration and partially slotted flap. To describe key features of ALL existing meshing options in Ansys Mesh module and discuss their applications (please refer to build-in documentation in the software).

Physics of Black Holes Essay -- physics space black holes
Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them. Karl Schwarzschild is credited with being the brilliant astronomer who developed the concept of black holes. In 1916, using Einstein's general theory of relativity, he began to make calculations about the gravity fields of stars. He concluded that if a huge mass, such as a star, were to be concentrated down to the size of an infintessimal point, the effects of Einstein's relativity would get really fairly extreme. Schwarzschild doubted that a star could get that small, and theorized that if a star did infact shrink upon itself like that, its gravity would remain the same and the planets revolving around it would remain in the same orbits they always had. Since then however, some of Schwarzschild's theories have been disproved, but most of his initial theories hold intact today. The Schwarzschild Radius, the maximum radius a body with a specific mass can have that won't let light escape, is named in his honor, and the equation of which is still in use today: Rs=2MG/(c^2) In truth, English geologist John Michell was the first to suggest the existence of black holes. He referred to them "dark stars" and based his calculations on Newt... ...ke for instance the two images below. The first is a two-dimensional representation of the gravity of a normal star. Imagine any object floating through space as a marble. Said marble rolling along the flat surface of the space will roll into the indentation made by the sun's gravity. If you flick the marble hard enough, it can roll out of the indentation and roll away. The second pic is a representation of the gravity made by a black hole. Notice that if the marble rolls into the hole, there's no way it can get out, since there is no end to the hole. Such prospects are intriguing, and provide science fiction novelists with endless material for their writings. None of these theories have been proved, and since we can't get close enough to a black hole to study one, they're all perfectly valid. Perhaps one day mankind will discover the truths behind black holes.

Gay Marriage: Social Calamity or Long Overdue? Essay
Abstract There is growing attention to the issue of marriage equality for gay people in this country. As of the writing of this paper, 16 of the 50 states in the United States of America have legalized gay marriage, either by legislation or by popular vote (Wisniewski, 2013). The discourse regarding the issue becomes quite contentious largely because of non-secular ideology that has demonized the concept of homosexuality for many years. As a sociological issue, the conflict has become a divisive force for many, from political powers as far down to the family level. The constitution guarantees equal rights for all in this country; freedom of religion, speech, etc. yet appears to stall when equal rights for the gay community are involved. There has been significantly more popular support for the cause recently, but the stigma and prejudice continue to linger. Is this a moral debate or has an outdated ideology become so embraced by many that the battle has only just begun? Are Rights Really Equal? When asked if one believes in equal rights for all citizens, the typical, rote response is a resounding ââ¬Å"Yesâ⬠. If the question becomes more specific as to include the right for homosexuals to marry, a hesitation follows. The concept of gay marriage is far deeper a societal problem for most because its roots lie in prejudicial perspectives that have permeated us for years. Before the fight for the right to marry, the gay community has long endured simply the right to exist openly without feeling pariah-like. The United States is not a theocracy, of this we are certain. However, there are many more religiously affiliated citizens than not. The First Amendment gives us freedom of religion, which should also include freedom from religion. The truth of the matter meets somewhere in between the two, especially when US currency bears ââ¬Å"In God We Trustâ⬠boldly on its face. There are political leaders who continue to evoke the name of God in their speeches, even thoughà the fact is that our founding fathers were mostly non-theists and the motto on our money did not initiate until 1958 or so. But people continue to view homosexuality as a ââ¬Å"sinâ⬠, therefore gay marriage is not an option. This issue has created a divide in this country, much like most other civil rights have. When slavery was abolished, it took years to establish anti-segregation laws. Civil change takes time, historically, and gay marriage is no different. Protests continue either in support of or against gay marriage, at times becoming violent. Families become divided when a member openly announces his or her orientation and disapproval prevails, sometimes resulting in families disowning or ostracizing that offender from the family. Government has been forced to become involved, due to an outcry for the various rights that are bestowed upon a married member of this society. Rights to inheritance and to personal medical information and decision making are two examples of spousal rights. Monogamous homosexual couples are denied these rights, since without marriage, the rights fall to their closest relative. Functional Sociology and Gay Marriage Society has long viewed traditional marriage a fundamental and necessary building block. Marriage is the institution by which our population is regenerated and offspring are socialized then integrated as functioning members. Functional theorists might argue that if the paradigm is changed to include same sex couples, social decay may follow, as the family unit is unable to function if not in the traditional way. Single parent households have been faulted with producing children that score lower in school than those from the traditional, two parent family, as well as have higher rates of unacceptable social behavior, such as drug abuse or teenage pregnancy. Functionalists believe children benefit from each gender parent in a different way, therefore require both to be whole. (Tischler, 2011) Conflict Theory and Gay Marriage Conflict theory maintains that society functions when a more powerful or accepted sector exerts its will and exceeds at the expense of less powerful or accepted portions. (Tischler, 2011). Since homosexuality has been regarded taboo by the majority for so long, heterosexuals have maintained their position of acceptance and normalcy in the US. Vocational positions,à especially powerful ones such as political leaders, have historically been heterosexual. We have a ââ¬Å"Presidentâ⬠and a ââ¬Å"First Ladyâ⬠; expected heterosexuality. For the stigma to be removed, traditionally expected and understood ways of life would drastically change. Would traditional, heterosexual marriage decay in the process? The Future of Marriage Regardless of sociological theory, religious belief, and cultural expectation, the movement towards acceptance of gay marriage is gaining momentum and losing the attached stigma. Gay marriage is legal in 16 states (Wisniewski, 2013), and gay couples right to adoption has increased. Heterosexual divorce rates remain hovering at a 50% mark, and have been for many years prior to homosexual marriage. Society is resilient, proving itself over years of change. The ideal aspiration would be for both homosexual and heterosexual married couples to simply co-exist; neither having any real influence over the othersââ¬â¢ success or demise.

Professor Tony J. Watson gained his BA in London in 1968, MSc in Loughborough in 1972, and PhD in Nottingham in 1976 (Business school n.pag.). The author published a number of reputable works on management and strategy development. His books cover the topics of his research interests including ââ¬Å"the organization theory and the sociology of work; managerial, entrepreneurial, strategic and human resourcing behavior in organizations; organizational culture; and ethnographyâ⬠(Business school n.pag.). The works by Professor Watson are highly appreciated by the economists and managers. They are used as the study materials at the business schools as well. Tony J. Watson is the ongoing member of a number of the memberships and fellowships. In particular, he is a member of the Chartered Fellow of the Chartered Institute of Personnel and Development (CPID), the member of the editorial boards of Human Relations, Journal of Management Studies, and Personal Review (Business school n.pag.).

Let's see if we can help you! Get your first paper with 15% OFF Learn More The Key Points of Criticism In Search of Management presents the interesting view on the organizationââ¬â¢s management as the author analyses the different aspects of the managerial work taking into consideration the responses of the middle class managers regarding their job. It can be stated that the book is unique as the majority of other authors have not considered the problem in this context. In should be noted that the most part of the research on management is based on the quantitative estimation of its quality and efficiency. The central theme of the book In Search of Management is the ââ¬Å"discovery of what management is look likeâ⬠(Watson 2001, n.pag.). The main goal of the author was to create the book, which would be helpful for the broad range of users. It was a challenging task taking into account the fact that people tended to draw a distinction between the ââ¬Å"academicâ⬠books and the ââ¬Å"practicalâ⬠manuals. It may be no accident that the author decides to present his dialogue with his management fellow. He tries to emphasize that there is a widespread opinion in the managerial community that the management in theory and the management in practice are two rather different concepts and that the academics do not capture the problems of real managerial work in their research quite often. Watson says that he tries to erase this distinction b etween the academic and practical management in his book In Search of Management. The author argues that ââ¬Å"the managers themselves, however much they tend to scorn the very idea of theory, are inevitably theorists of a sortâ⬠(Watson 2001, p. 2). In my view, the author has achieved his goal. He masterly applies the theoretical conceptions to the practical issues arguing the strengths and weaknesses of the organizationââ¬â¢s management. In addition, Watsonââ¬â¢s book is not overloaded with the terminology and, thus, is appropriate for the readers of the wide range. The book is written in the form of a story. The comprehensive language and the structure of the book support its universality. Rosemary Stewart (1994) states in her book review published in The Independent that the book can be described as the ââ¬Å"diary of a professor at workâ⬠(Stewart 1994).Advertising We will write a custom book review sample on The Review of In Search of Management by To ny J. Watson specifically for you for only $16.05 $11/page Learn More In Search of Management encompasses the realities of the world of management. Stewart (1994) claims that the book ââ¬Å"is about people and its purpose is to help organizations surviveâ⬠(Stewart 1994, n.pag.). In my view, these words reflect the essence of the book and its value. The author puts the emphasis on the role of people in organization. That is why he tries to consider the managerial work from the standpoint of the process of communication and collaboration with people. Watson states that the efficiency of management is directly related to how well people inside the organization work together. The concept of the ââ¬Å"teamâ⬠plays a vital role in his book. Watson tries to prove the idea that the long-term success of the organization is determined by the effectiveness of the team work. In his book, Watson analyses the reasons for failure of the British manufacturing companyà ¢â¬â¢s strategy. Although the employees of the company were rather competent in their work, the company could not progress further and was not able to compete in the market successfully. It seemed that the management lost the direction in the way of its strategy realization. The managers claimed that everyone in the organization had their task and everyone did it well but it did not helped. The author of the book argued that the problem of this company boiled down to the fact that its managers paid too much attention to the philosophical aspect of management. As a result, employees were frequently told about the values and goals of the organization. However, what the company lacked was the sufficient attention to the technical aspect of their work. The commitment of the employees was not enough to improve the performance.Advertising Looking for book review on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More In Search of Management is very interesting book, which is worthy to read for both the academics and practitioners. Willmott (1995) describes the book as ââ¬Å"an insightful, eloquent and entertaining account of the complexity, chaos and ambivalence that is so carefully expurgated from the majority of academic textbooks, guru handbooks and scholarly monographsâ⬠(Willmott 1995, n.pag.). It should be said that the first edition of In Search of Management was published in 1994. However, the ideas presented by the author remain urgent nowadays. Prof. Watson says that it is not surprising that his book is still popular as the factors influencing the managerial work remain the same. He states that, although the significant changes have occurred in the business world since the time of the first publishing of his book, the nature of the problems, which the managers should solve, have not been changed. Dr. David Potter claims that In Search of Management remains up-to-date as ââ¬Å"t he ideas of Watson still sound very practicalâ⬠(Potter 2010, n.pag.). Conclusion In order to sum up all above mentioned, it should be said that the book In Search of Management: Culture, Chaos, and Control in Managerial Work by Tony J. Watson represents the important material for study and provides the background for further research. The author touches upon the urgent problems of the managerial work. The central theme of the book is the search of the essence of management. The analysis presented in the work is based on the interviews with the managers of the company. The author tries to explain why the commitment of employees may be not enough to achieve the goals of the company. In spite of the fact that the first edition of the book was published 19 years ago, it remains relevant today. Overall, the book In Search of Management is the interesting work, which I recommend to read everyone, who is interested in management. References Business school.

Rubber bands Essays
Rubber bands Essays Rubber bands Paper Rubber bands Paper The aim of this experiment is to find how the amount of stretching, when shooting a rubber band, affects the length of the shot. Hypothesis When you stretch an elastic rubber band, you store potential elastic energy inside it. When the rubber band is released, the potential elastic energy will be transformed into the same amount of kinetic energy. This will cause the rubber band to move, and the more kinetic energy we have, the longer the rubber band will fly. Thus, the more stretching performed on the rubber band, the longer it will fly. Stand, double muff, 2 flags, 2 rubber bands with an circumference of 0. 20 respective 0. 22 m, measuring tape with an uncertainty of , and a ruler with an uncertainty of . Procedure The experiment was performed indoors at normal room temperature. We of course began to set up our equipment in a proper way. (see picture) The setup ensured that we would have the same angle of the rubber band in each shot. Three different lengths between the flags were used, 0. 15 m, 0. 20 m and 0. 25 m. When the rubber bands were attached to the flags, the total circumference of the rubber bands then became 0.30 m, 0. 40 m and 0. 50 m, and the increase in length of the rubber band was different dependent on which rubber band was used (see table). Rubber 1 was not as slack, as thin, and had a smaller circumference than rubber 2. Five shots with each rubber band on each length were done, and a mean value was calculated. The values were inserted into a diagram in order to increase and simplify the comprehension of the result. The following result was reached when investigating the shot length on different stretching lengths: These values are then inserted in a graph, which looks like following:On the x-axis we have the stretch of the rubber band in meters, and on the y-axis we have the shot length in meters. The different points represent the length of the shots on different stretching values. The lines are drawn to best fit. Conclusion We see a clear result, and it does indeed follow our hypothesis. The more the rubber band is stretched, the longer the shot length becomes. As kinetic energy is required for anything to move, we can draw the conclusion that that kinetic energy must have come from somewhere, and in this case it was the potential elastic energy in the rubber band, which was stored in it when stretched. However, another interesting result was reached. As we see in the diagram, the lines drawn to best fit are not linear, but shaped as curves. This implies that the increase in shot length is not correlating to the increase in stretching. As the table and the diagram show, the flight in meters per stretched meter decreases the more you stretch the rubber band. We also see that the curves cross each other. Rubber 2, which had a shorter flying distance, would when stretched only 0. 004 m, have a greater range than rubber 1 with the same stretching. This low value of stretching of course is quite hard to measure as you probably would not have been able to release the rubber band at all. Perhaps if you would have used rubber bands in a larger scale and with some differentiating property, a difference would have been possible to actually measure. However, to draw any conclusion like this from the graph probably should not be done. Our measuring points are nowhere close to the actual crossing of the lines, but at least a hint about what might happen is given, even though we can not draw any certain conclusions.
