Stealth Technology - 4376 Words

STEALTH TECHNOLOGY ABSTRACT: Stealth technology also known as LOT (Low Observability Technology) is a sub-discipline of military electronic countermeasures which covers a range of techniques used with aircraft, ships and missiles, in order to make them less visible (ideally invisible) to radar, infrared and other detection methods. The concept of stealth is not new: being able to operate without giving the enemy knowledge has always been a goal of military technology and techniques. However, as the potency of detection and interception technologies (radar, IRST, surface-to-air missiles etc.) has increased, so too has the extent to which the design and operation of military vehicles have been affected in response. A stealth vehicle will†¦show more content†¦Rapid development of radar during WWII led to equally rapid development of numerous counter radar measures during the period; a notable example of this was the use of chaff. * The term Stealth in reference to reduced radar signature aircraft became popular during the late eighties when the F-117 stealth fighter became widely known. The first large scale (and public) use of the F-117 was during the Gulf War in 1991. However, F-117A stealth fighters were used for the first time in combat during Operation Just Cause, the United States invasion of Panama in 1989. Since then it has become less effective due to developments in the algorithms used to process the data received by radars, such as Bayesian particle filter methods. Increased awareness of stealth vehicles and the technologies behind them is prompting the development of techniques for detecting stealth vehicles, such as passive radar arrays and low-frequency radars. Many countries nevertheless continue to develop low-RCS vehiclesShow MoreRelatedIntroduction Of Stealth Technology : Technology2104 Words   |  9 PagesINTRODUCTION OF STEALTH TECHNOLOGY: Most of the common people would be unaware of this technology and they would first ask what is this technology? Stealth technology is that technology which covers the range of technology which is used by defence men, air craft s, missiles, satellites so that they become invisible to the radar , infrared, solar and other detection methods.

Brave New World Analysis on Characters â€Å"The world’s stable now. People are happy; they get what they want, and they never want what they can’t get†¦ they are so conditioned that they practically can’t help behaving as they ought to behave† (Huxley 198). Many people speak and dream about a perfect world, for the problems which we face in the present world to simply just go away. We will write a custom essay sample on Brave New World Analysis on Characters or any similar topic only for you Order Now Brave New World is a novel which shows an example of what life would be like in a utopian society. Read also Analysis of Characters in Flannery O’Connor’s â€Å"The Life You Save May Be Your Own† It shows the differences that civilization has against the savage world, which is how we live in present day. The characters in Brave New World all experience the controversy between nature vs nurture ultimately leading to their unhappiness. An individual can be given everything they need but yet still live unhappy. This especially can be seen with one of the main characters in Brave New World, Bernard. He was an Alpha Plus, the highest class in civilization, but unfortunately didn’t look like most Alphas (69). Despite his class, he was an outcast and spent most of his time alone. The narrator in the novel explains, â€Å"The mockery made him feel an outsider; and feeling an outsider he behaved like one, which increased the prejudice against him and aroused hostility about his physical defects†¦ which increased the sense of being alien and alone† (68). Although he had a high title it didn’t make him feel happy. He felt like there was more to life than a set routine they were all given in civilization. Bernard felt himself different; he wanted to feel emotions and not just live day by day on fake happiness. Bernard expresses his frustration to be feel different when he states, â€Å" But wouldn’t you like to be free to be happy in some other way, Lenina? In your own way, for example, not in everybody else’s way† (90). Bernard was tired of being enslaved by his conditioning. The people of the New World were all taught to think, act, and see things a certain way. No individuality. Living in a controlled world doesn’t cause happiness, it just numbs people of actual feelings. Lenina is a â€Å"pneumatic girl†, very popular, and has spent a night with almost all of the men in civilization. Pleasure was key in the controlled world. She found herself wanted by men, and like most women enjoyed having sex with men. When Lenina began talking to Bernard, she didn’t agree with him on wanting more to life. She’d rather be on soma, a drug that would numb them from any true emotions, whenever she felt a little uneasy, just like everyone else. Lenina’s unhappiness comes when Bernard takes her into the Savage world and she sees how John and Linda and everyone else is living. Her immediate reaction was to find some soma. She couldn’t believe how people grew old, suffered, and had to deal with everyday problems. Lenina began falling for John and quickly realized that she wanted something specifically with him that most men couldn’t satisfy. Lenina states to her friend Fanny, â€Å"And what about a man– one man. Hes the one i want†¦ and in intervals I still like him. I shall always like him† (171). Lenina had never felt like this before, therefore she didn’t know how to handle it. The only thing she knew of about men was to have sex with them. When John rejected sleeping with her, she was completely taken by surprise. The narrator explains, â€Å" Drying her eyes†¦ she pulled out her soma bottle†¦ hers had been more than a one-gramme affliction† (157). Never being in the position, she immediately turned to soma to help her cope with what she was feeling. She has been living numb to emotion and for the first time she was forced to feel unwanted and ached for an escape. Linda was a Delta in a civilized world who went on a trip with the Director to the Savage world. Unfortunately for her she had fell and bumped her head, causing her to get lost and be taken in by Native Americans (112). The Director searched for her but was never able to find her. To her dismay she was pregnant and had a baby named John. Linda only knew how to act like a civilized person. She was very promiscuous and like the controlled world, began to sleep around with different men. This was strange to the Savage World and they then began to call her names and make her an outcast. Linda stated, â€Å"I was so ashamed. Just to think of it; me a Beta– having a baby† (114). Having John was very difficult for her. Linda had no idea how to be a mother, how to nurture, or even how to be a good role model for the child. Linda thought of how perfect her life would be if she were to return to the civilized world, returning to soma. She was willing to do whatever just to be back in the New World, â€Å"†¦ here was her appearance†¦ so the best people were quite determined not to see Linda. And Linda, had no desire to see them. The return to civilization was for her the return to soma† (142). Linda thought all her problems would be solved by going back to the controlled world, but in fact they made her even more depressed and unwanted. She had nob ody except for John and she would rather be numb and not feel anything than deal with civilization. Where would she find true happiness if in the Savage World she is discriminated for her ways, and in civilization she no longer fits in. Living in the Savage world, one can only imagine how perfect the civilized world could be. Unfortunately, having came from the savage world John had something to compare the controlled world to. Being the son to a women in the civilized world, he had heard nothing but wonders about it. On the other hand, having been raised in the Savage World allowed John to learn morals and want to find a purpose in life. When John reached the civilized world he was completely disappointed on how fake everything and everyone was. â€Å" How much I love you, Lenina†¦ or always†¦ to make a promise to live together for always† (174). John had seen his mother sleep with so many men and get teased by it that he did not want to just sleep with the women he liked. He wanted to marry and be with just that one. For Lenina this was just nonsense, and that just made John not want anything to do with her. He wanted to feel a special connection with Lenina that she had never had before. By the e nd John decides to be isolated because he would rather deal with his emotions than live in a â€Å"perfect† world numb and unhappy. Ultimately, the utopian society didn’t mean solving all problems and people forever living happy. If a civilization is all an individual knows, how is it that they still manage to be unhappy? There is no happiness when people are living numb from what is really going on. When it comes to the topic of a utopian society vs the kind of society in which we currently live in, I think there is really no solution. We are human and as much as they can try to condition human beings, there is still going to be some kind of downfall. How to cite Brave New World Analysis on Characters, Papers

Information Systems for the Banking amp; Financial Sector: Audit is one of the major controls for monitoring management activities in the banks and financial institutions. In a computerized environment, IS audit is a very effective and necessary activity. Usually the IT implementation in the banking and financial organizations is done by adopting a mix of different methodologies – internal development and deployment and third party product development and deployment. In case of internally developed and deployed IT systems, IS audit will require to be done by a team of specially trained internal or external auditors. However, it is preferable to have the IS audit conducted with the help of suitable external agencies with the required skills and expertise to ensure independent nature of audit. In case of development and deployment of the IT systems by third parties, the IS audit requires to be conducted by trusted auditor/s with skills and expertise, required for the purpose. 3. 2. Computer information system(s) (CIS) Computer information system is a field studying computers and algorithmic processes, including their principles, their software and hardware designs, their applications, and their impact on society while IS emphasizes functionality over design. Any specific information system (IS) aims to support operations, management and decision making. In a broad sense, the term is used to refer not only to the information and communication technology (ICT) that an organization uses, but also to the way in which people interact with this technology in support of business processes. Some authors make a clear distinction between information systems, computer systems, and business processes. Information systems typically include an ICT component but are not purely concerned with ICT, focusing instead on the end use of information technology. Information systems are also different from business processes. Information systems help to control the performance of business processes. Alter argues for advantages of viewing an information system as a special type of work system. A work system is a system in which humans and/or machines perform work (processes and activities) using resources to produce specific products and/or services for customers. An information system is a work system whose activities are devoted to processing (capturing, transmitting, storing, retrieving, manipulating and displaying) information. As such, information systems inter-relate with data systems on the one hand and activity systems on the other. An information system is a form of communication system in which data represent and are processed as a form of social memory. An information system can also be considered a semi-formal language which supports human decision making and action. Information systems are the primary focus of study for organizational informatics 4. Types of information systems Figure : Types of Information Systems. A four level pyramid model of different types of Information Systems based on the different levels of hierarchy in an organization The classic view of Information systems found in the textbooks in the 1980s was of a pyramid of systems that reflected the hierarchy of the organization, usually transaction processing systems at the bottom of the pyramid, followed by management information systems, decision support systems, and ending with executive information systems at the top. Although the pyramid model remains useful, since it was first formulated a number of new technologies have been developed and new categories of information systems have emerged, some of which no longer fit easily into the original pyramid model. Some examples of such systems are: Data warehouses Enterprise resource planning Enterprise systems Expert systems Search engines Geographic information system Global information system Office automation. 4. 1. Computer (-Based) Information System A Computer (-Based) Information System is essentially an IS using computer technology to carry out some or all of its planned tasks. The basic components of computer based information system are: Hardware- these are the devices like the monitor, processor, printer and keyboard, all of which work together to accept, process, show data and information. Software- are the programs that allow the hardware to process the data. Databases- are the gathering of associated files or tables containing related data. Networks- are a connecting system that allows diverse computers to distribute resources. Procedures- are the commands for combining the components above to process information and produce the preferred output. The first four components (hardware, software, database and network) make up what is known as the information technology platform. Information technology workers could then use these components to create information systems that watch over safety measures, risk and the management of data. These actions are known as information technology services. Certain information systems support parts of organizations, others support entire organizations, and still others, support groups of organizations. Recall that each department or functional area within an organization has its own collection of application programs, or information systems. These functional area information systems (FAIS) are supporting pillars for more general IS namely, business intelligence systems and dashboards. As the names suggest, each FAIS support a particular function are within the organization, e. g. : accounting IS, finance IS, production/operation management (POM) IS, marketing IS, and human resources IS. In finance and accounting, managers use IT systems to forecast revenues and business activity, to determine the best sources and uses of funds, and to perform audits to ensure that the organization is fundamentally sound and that all financial reports and documents are accurate. Other types of organizational information systems are FAIS, Transaction processing systems, enterprise resource planning, office automation system, management information system, decision support system, expert system, executive dashboard, supply chain management system, and electronic commerce system. Dashboards are a special form of IS that support all managers of the organization. They provide rapid access to timely information and direct access to structured information in the form of reports. Expert systems attempt to duplicate the work of human experts by applying reasoning capabilities, knowledge, and expertise within a specific domain. 5. How they assist in business planning? 5. 1. Information Storage and Analysis At the date of publication, many companies no longer manage their data and information manually with registers and hard-copy formats. Through the adoption of information systems, companies can make use of sophisticated and comprehensive databases that can contain all imaginable pieces of data about the company. Information systems store, update and even analyze the information, which the company can then use to pinpoint solutions to current or future problems. Furthermore, these systems can integrate data from various sources, inside and outside the company, keeping the company up to date with internal performance and external opportunities and threats. 5. 2. Assist With Making Decisions The long-term success of a company depends upon the adequacy of its strategic plans. An organization’s management team uses information systems to formulate strategic plans and make decisions for the organizations longevity and prosperity. The business uses information systems to evaluate information from all sources, including information from external references such as Reuters or Bloomberg, which provide information on the general economy. This analysis of and comparison to market trends helps organizations analyze the adequacy and quality of their strategic decisions. 5. 3. Assist With Business Processes Information systems aid businesses in developing a larger number of value added-systems in the company. For example, a company can integrate information systems with the manufacturing cycle to ensure that the output it produces complies with the requirements of the various quality management standards. Adoption of information systems simplifies business processes and removes unnecessary activities. Information systems add controls to employee processes, ensuring that only users with the applicable rights can perform certain tasks. Further, information systems eliminate repetitive tasks and increase accuracy, allowing employees to concentrate on more high-level functions. Information systems can also lead to better project planning and implementation through effective monitoring and comparison against established criteria. 5. 4. Considerations Implementing information systems within an organization can prove to be costly. Implementation costs include not only installation of the systems but also employee training sessions. In addition, employees may see the adoption of information systems as an unwarranted change and, thus, may resist this change. Resistance to change can hinder business operations and can cause employee turnover. Companies should have leadership in place to assess the adequacy of the decision to have an information system and to guide the company through the transition phase and weigh information systems cost against the potential benefits. 6. Examples of IS that are useful for communication 6. 1. Information and communications technology (ICT) It is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information. The phrase ICT had been used by academic researchers since the 1980s, but it became popular after it was used in a report to the UK government by Dennis Stevenson in 1997 and in the revised National Curriculum for England, Wales and Northern Ireland in 2000. As of September 2013, the term ICT in the UK National Curriculum has been replaced by the broader term computing. The term ICT is now also used to refer to the convergence of audio-visual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives (huge cost savings due to elimination of the telephone network) to merge the audio-visual, building management and telephone network with the computer network system using a single unified system of cabling, signal distribution and management. The term Infocommunications is sometimes used interchangeably with ICT. In fact Infocommunications is the expansion of telecommunications with information processing and content handling functions on a common digital technology base. 7. CONCLUSION The IS technology is need for every business. It’s cheaper and efficient way in communication to maintain data to execute reports to find out where are we now in business?
