Electro-optics and Infrared Essay Example for Free

Electro-optics and Infr atomic get 18d EssayElectronic warf be involves the utilization of techniques, equipment and devices to counteract or deny the enemy from victimization microwave radar, communications and some otherwise radio wave devices. The EW techniques can be further subdivided into electronic support, electronic attack and electronic protection (Frater Ryan, 2001). Electronic support (ES) involves actions taken by an operational commander to search, intercept, identify and locate sources of electromagnetic skill. ES is considered to be passive as it involves using passive measures which do not generate their own energy. Electronic attack (EA) involves using electromagnetic energy to attack facilities, equipment or personnel in coiffe to destroy the enemys scrap capability. EA is taken be an active technique as it involves jamming, neutralization and electronic deception, which are usually noisy since they generate their own energy (Goodman Carus, 1990). Ja mming entails utilisation of electromagnetic energy to pr so fart radio signal transmission. In neutralizing the enemys signal, extremely high levels of electromagnetic radiation are utilized to damage permanently the enemys electronic equipment.While in electronic deception false or misleading signals are displace in order to deceive and confuse the enemy. Electronic protection (EP) entails the actions taken to protect facilities, personnel and equipment from effects of EW that would destroy or damage their combat capability. EP involves using active and passive techniques (Frater Ryan, 2001). In the past, EW systems were mainly concerned with the microwave spectrum region and nowadays it is continuously shifting to the longer wavelengths of IR and also to the visible region.The current weapon systems are increasingly exploiting a mixture of sensors in order to overcome the adverse climatic conditions (Szweda, 2000). To such systems, countermeasures are also take which includ e compact diode laser light sources. Additionally, small and light equipment which provide a wide range of sensors and countermeasures is also needed (Selex Galileo, 2009). Land environment EW systems in land operations are very important to the military since most of their operations are done on land.In most countries their military forces are muted equipped with old equipment which were utilized in the Second World War and thus are formulation to adopt new ones. For example, Canada has not yet adopted the new equipment and whence is planning to update its land EW equipment in a few old age time (Farley Gauthier, 2008). According to Bellamy (1987), developments in the weapons platforms and protection remove taken place gradually and slowly, and the external appearance of the battle theatre of operations can slowly be seen for the stratum 2000 or 2010.However, in the EW field changes require occurred rapidly as new equipments are being made which serve the military better. The EW field has become like a battle field as military forces are trying to outdo each other. For instance, in equipping its military forces, the British government purchased the first soothsayer equipment at cost of about $220 million and was to start using it in 2006 (Deagel, 2003). Many countries inclusive of the United State of the States are investing many cash in research on the EW systems in order to increase the military strengths (Szweda, 2000).The primary bands of the radar and its frequencies in the electromagnetic spectrum are VHF, UHF and it continues onwards. The commonly used wave frequencies by the US, NATO and other military forces, ranges from about 26. 5 gigacycle per second to about 170 GHz (Bellamy, 1987). The communication channel contains a band of frequencies, however, during communications the equipment are tuned to certain frequency in order to communicate with the other person on the other side. For high communication quality extensive band are infix ed, but are usually prone to jamming and interception by another person who could be the enemy.To avoid jamming or interception, define bands are therefore preferred and thus are most commonly used. On land EW systems and particularly the radar components ingest many functions which are very useful to the military and some of them include locating weapons, tracking shell, charge of battlefield, ground vehicle ego protection, subsurface object detection, among others (Bretton, 1986). This education is essential for the military as it saves the lives of many military personnel. For instance, locating weapons allows military to detect land mines or bombs which have been situated down as a trap and hence are able to deactivate them.There are several EW techniques currently being used. For instance the British army is equipped with soothsayer EW equipment which is used for detecting and identifying radar and radio signals on the battlefield. This equipment is usually mounted on li ghtweight and ar more(prenominal)d military vehicles. Currently, the neodymium-YAG laser is also being used as optical range finders, however, the equipment is undergoing improvement in order to increase its smoke penetration mightiness (Margiotta, 2004). Another technique being utilized is the signal intelligence.Signal intelligence (SIGNIT) This technique involves gathering intelligent information by intercepting signals between individuals using electronic equipment (Lindborg, 1997). It entails use of crypt abbreviation since sensitive information is usually encrypted. Traffic analysis is also used in some cases to get valuable information. Through merchandise analysis information concerning the sender and the receiver of that information and the quantity of information shared between the two individuals can be easily obtained (Shulsky Schmitt, 2002).This technique is broad and thus has many subdivisions however, the two main subdivisions include communication intelligence (C OMINT) and electronic intelligence (electronics intelligence). Currently, the SIGNIT techniques also involves use optical devices thereby making it more in effect(p) and efficient. a) COMINT This type deals with voice information or messages which are derived from an interception of foreign communications (Lockwood, 2006). This technique is used for text interception, voice interception, signal channeling interception and for monitor friendly conversations (Yusof, 1999).Text interception is currently not being used by many military forces. Military forces of nations of the former Soviet Union are the still using it and it involves use of Morse code. Radio frequencies are scanned for character sequences and facsimile in order to get intelligence information. In voice interception the technique involves sense of hearing to voice communications over radios, telephones or through wiretaps. In cases where the communication is encrypted, the information is first decrypted through an int ro-electric diagram process for it to be heard.However, the interceptor has to understand the language used in order to get the information. Furthermore, the technique is also utilized to monitor own communication in order to avoid leaking intelligence information to the enemy. b) ELINT This involves use of electronic sensors to gather intelligence information. This technique focuses mainly on non-communication signals intelligence. The process entails signal credit through analysis of certain parameters, because matching the signal parameter with known parameters or recording it as potential new emitter.The information collected is usually highly classified and hence given often security to prevent unauthorized individuals from accessing it. The basic ELINT target are all radar types and these include fire control navigation, surveillance and all radars deployed on sea, land and even in the air. Other targets include navigation systems, data links, command links and telemetry links (Ince et al, 2000). In most cases and especially in times of peace, ELINT is performed regularly prior to a specific mission.Peace operations have the objective of obtaining the maximum possible information on a complete electromagnetic radiation within the areas of interest in any particular nation. In such cases, special ships, satellites, aircraft and land based ELINT facilities are utilized which operate in comprehensive reconnaissance schedules. Maritime In the maritime environment, the EW systems have to meet their operational capability requirements in order to be effective and hence meet their objectives.However, there is a high occurrence chance of adverse electromagnetic hinderance between the EW and sensor system, since the maritime platforms operate jointly and also the number of EW and sensor system fitted in the maritime platforms has been increasing continually (DallArmi-Stoks et al, 2007). EW systems are mainly utilized for intelligence gathering and for self protection. They are utilized for maritime surveillance because of their capability in detecting, classifying and identification of the targets by intercepting their communication and radar emissions.However, they are not useful when the target element is observing radio silence since there are no emissions of electromagnetic radiations (Ince et al, 2000). In target identification during surveillance, the method used by the EW systems involves finding several features in the intercepted signals which are unique to all emitters. These features mainly include modulation, carrier frequency and stability, types and number of emitters, pulse width and pulse repetition frequency (Ince et al, 2000). Through the library carried by the interceptor, the target is identified.The library is usually obtained through ELINT as it collects and records much data from non-communication equipment radiation. The EW systems are usually installed in submarines or vessels for combat. There are several mod ern equipments which are currently being used but in limited number because of their cost. One is the naval laser warning system which is installed in surface ships. This system enables the ships command team to detect the comportment of laser activity in the adjoin (Saab, 2009).They are essential for situation awareness as they allows individuals to detect any laser activity in their surrounding from the enemy. The laser warning system detects, classifies and identifies the threats and allows individuals to prepare themselves from any attack and to maneuver to safer locations. This system is also used in submarines for detection of anti-submarine LIDAR. Another EW system used is the submarine ELINT systems, which utilizes phase interferometer in order to increase accuracy when finding direction (Saab, 2009).This system comprises of radar Warner receiver antenna, an ELINT antenna, and EW processing unit installed in the vessel. Air Environment In the air environment, EW systems ar e used mainly for jamming, finding direction and for intelligence analysis of the ground military forces telephone, radio and Morse transmissions. Currently, the EW systems being used use complex command and control communications to link command posts and other posts such as weapons and radar posts (Boyne Fopp, 2002).In the past EW systems in the air force were not taken to be vitally important, but in the recent years they have become one of the critical parts of the air force plans (Gons, 2004). This is because the effectiveness of an aircraft depends greatly on the ability of the EW system. EW systems are essential for the military force to maintain dominance in the air and space. In aircrafts, the use of barrage jamming by simultaneous impede a wide range of frequencies is currently becoming outdated since it utilizes much electrical forefinger (Brown, 1986).Currently, lasers are being increasingly used because of their low power consumption, space saving, and many other adv antages. A number of aircrafts are fitted with the modern optical devices which are entails use of lasers. One of the aircraft with modern optical devices is the air entirelyification version of the Tornado (Brown, 1986). Optical devices used are the lasers radar which are considered to be less radical and helpful in visual recognition. There are also useful for aircraft recognition and tracking at long ranges which are usually achievable by air to air missiles.However, lasers have very narrow frequencies and thus can easily be tracked or intercepted. Furthermore, currently transferring electronic warfare capabilities across triune platforms is not possible (AFPN, 2008). This can be attributed to lack of data standard or hardware. Conclusion and recommendation EW system EM compatibility should be addressed and managed properly using the correct procedures get in place in order to reduce EM interference. Otherwise the process of eliminating electromagnetic interference will becom e expensive and might make a motion the operational capability of the entire EW system.Consequently, adequate training might be helpful in ensuring that the proper procedures are followed. Ensuring that the right personnel have sufficient skills and knowledge on matters concerning EW system electromagnetic compatibility, interference problems will be greatly reduced. In addition to that, policies need to be veritable and implemented to ensure that the correct procedures for addressing and managing the EW system electromagnetic compatibility are utilized. Policies will ensure that the technicians follow the proper procedures and not their own short impose procedures.In managing the complexity and the capability problems related to electromagnetic radiation in the EW system, it is essential that the electromagnetic capability and interference be assessed during the stages of planning, designing and even the development of the system. In addition to that assessment should be done du ring the installation and operation of the electronic and electrical equipment and all the stages should be governed by the electromagnetic interference control plan. Additionally, more research needs to be done on the EW systems used in the aircrafts.This is because transference of electronic warfare capabilities across multiple platforms is currently not possible. Since there is no data standard or hardware in existence, if one particular aircraft has tremendous capabilities against a certain threat, the capabilities have to be regenerated separately for other platforms. This process therefore wastes a lot time and money in regeneration of new aircrafts. This problem is not just affecting the air force but the entire military force. Researchers therefore need to concentrate more on weapon systems compatibility with electronic warfare programs.With more research standardized EW programs that are compatible with all or majority of weapon systems will be developed. In spite of the la sers being easily intercepted, they provide a number of useful advantages which include accuracy and long distance coverage. In order to eliminate the disadvantages in using lasers, research is essential and thus researchers need to find ways of maximizing the advantages of lasers and minimizing the disadvantages. However, researches need many funds and thus governments and other organizations need to invest money in supporting these researches.Furthermore, an integrated approach is also needed that combines sensors, weapons, self protection systems and the centralized countermeasures systems. The approach entails use of preprogrammed automated control, command and communications networks which can transmit data from systems that collect it to EW systems. Consequently, a centralized command facility should be put in place which allows senior military officers to prioritize the threats and to determine the methods to use against that particular adversary system.Additionally, an inte grated intelligence system is required which combines the large amount of data collected by the sensors and then transforms it to useful information. In conclusion, funds are essential in achieving all the above recommendations. Researches and especially scientific researches are usually expensive as they require modernized equipment, enough scientist and engineers who have adequate skills and knowledge. Governments and other world organizations therefore need to invest more money in electro-optic EW systems since they provide many advantages which are cost effective and efficient and thus useful for peace missions.

Fahrenheit 451 Analysis Essay Example for Free

Fahrenheit(postnominal) 451 Analysis EssayThe theme of Ray Bradburys classic Fahrenheit 451 can be viewed from several different angles. First and foremost, the book gives an anti-censorship message. Bradbury understood censorship to be a natural outcropping of an overly tolerant society. Yet, the lifter Guy Montag is unrivalled of the few that is courageous enough to find out the truth for himself. This unexpected discovery on the corruption of society challenged traditional values, companionship and beliefs. The personal freedom to the right of an individual having the freedom of expression when he utilizes the issue of censorship in Fahrenheit 451. In Bradburys novel, society has evolved to such an utmost(a) that all literature is illegal to possess. Because of the trouble books may cause, they were banned altogether. For example, one company might think they had a really great predilection and wrote it in a book, however, the other group might object to something that h as been written, that means the book will have to be modified and therefore censorship begins. Soon, another group objects to something else in the book, and it is again edited, eventually the original product will be lost.Because of this presented danger, no longer can books be read, not only because they might provoke someone, simply because books raise questions for the people that the government cannot answer. The intellectual thinking that comes from noesis can often be dangerous, yet, who would want to do that when they can take the comfy route? Ignorance is bliss applies perfectly here. The government would rather rule the people orderly than have them start a revolution with acquaintance. This philosophy, according to the book, completely ignores the benefits of knowledge. True, knowledge can cause disharmony because it causes people to ask why, notwithstanding in many ways, knowledge of the past, which is recorded in books, can prevent humanity from making similar mi stakes in the present and future.The society envisioned in Fahrenheit 451 is corrupted. As Captain Beatty explains, government control of peoples lives there was not a conspiracy of dictators, but a consensus of everyday people instead. The citizens are so weak-minded that they dont want to think for themselves and solve the troubling problems of the world. They dont have a good deal emotion, because they prefer pleasure over hurt. The only way they can do this is to not care. The parlor women, for example, cannot see past the surface. They are more interested in looks than reality they are so shallow that they cannot see ones true qualities. It is far easier to live a conduct of seclusion and a life history where technology will provide you with all necessities. Yet more importantly, Fahrenheit 451 described the people in that society as anti-social.Clarisse, the only normal miss mentioned that people in that society doesnt talk much, at all. They are either shouting or dancing around like wild (30), but the key point is, people dont talk about anything (31), they name a lot of cars or clothes or swimming pools broadly speaking and say how swell (31) They do not quite live in the reality, only using abstract things to entertain themselves. They all say the same things and null says anything different (31) because in their eyes, technology and the government is always correct. This is very similar to our world today, almost everyone some kind of technology television, computer, hand held devices. When we have a choice between technology or nature. It is almost certain that technology wins. We are on the computer three to four hours a day, doing work, checking email, social media, or just simply surfing the web. Our everyday life is technology we depend on it so much that it is almost impossible to live without it.People in the novel are afraid of themselves, of what their minds are capable of doing. They fear the thought of knowing, which leads them to d epend on others, such as technology and the government to think for them. The lift out example would be the protagonist Guy Montag. His entire view on life shifted as the book progressed. He was originally a normal fireman, but when he met his neighbor Clarisse McClennen, who was considered a misfit in the society, he began to see things differently. Instead of burning books because its useless information to the public, he now wants to share its knowledge with the whole world. Montag is at war with the society, hes battling against the common knowledge and laws, trying to shine some light on the people.Thus, the book successfully advocates the idea that men should think for themselves, not let technology or any outside sources decide for them. Technology may provide you with joy, but to live life to the fullest, you have to try everything, and there are no substitute for the treasure you can find in books. Its like Montag said, I went around doing one thing and feeling another. (1 31) as he reflects on all the trouble that he has gotten into because he has not been true to himself. Although this path might not be easy, it is necessary for any society that doesnt wish to repeat the mistakes of the past to earn knowledge. Our society today needs to realize that before it is too late.

The American Way of War

The the Statesn personal manner of WarThesis The United States has developed distinct the Statesn focussing of warfare.Since 1941, the United States of America had developed an American way of war based on engine room, precise habit of power from distance and employment of Special Operation Forces (SOF) in clubhouse to find, fix and mark adversary forces and expose them to precise air and ground fire. Additionally, outstanding use of the Combined Arms Maneuver and incorporation of all on tap(predicate) enablers distinguish the American way of war from opposite nations.The term American Way of War1 was mentioned for a first time in early 1970s with the outcome of The American Way of War written by Russel Weigley who examined the key political and military figures from George Washington to Robert McNamara and their approaches to the war. He wrote that The American Way of War seeks on the inquisition of a crushing military victory against opposing army, using a strategy of an a ttrition or annihilation. According to Weigley, the United States military and political leaders seek to destroy adversarys military capabilities and to conquer their capital city in order to force them to stop the war and to start postwar negotiations under already established United states terms and conditions.2 Additionally, he made clear distinction between the United States forces and most of the European armies, meaning that the United States unremarkably will capitalize their military victory achieving strategic success after war in order to keep or extend the influence by politics and diplomacy.Some writers argued that the United States did not develop The American Way of War and instead of the term mentioned above, they were arguing that the United States has developed The American Way of Battle3, because the most of the western armies along with the US Army were studied Napoleon, Clausewitz, Moltke, and developed tactics, procedures and doctrines according to their way o f warfare. Anyway, the one thing that distinguish the US Army from an new(prenominal)(a)(prenominal) western armies (British, German, French) in particular after WW 2 was the US Army ability to bring to war more than some countries and armies could even imagine.During the WW 2, the United States Army destruct most of the German and Japanese cities using strategic bombing on a daily base and making them incapable of conducting offensive doings and to declare fighting for a long period of time. According to Max Boot, and his article The New American Way of War, he wrote that the Civil War, reality War I, and World War II were won not by tactical or strategic brilliance but by the sheer weight of numbers the direful devastating power that hardly a fully mobilized and highly industrialized democracy can bring to bear.4 The United States brought to the WW 2 more than many otherwise country, and even more important, the United States were able to keep on that battle rhythm an d to finish the WW 2, along with their allies as victorious. From the other side, conflicts in Korea and Vietnam shoved that the awesome destructive power5 was not enough to achieve success, so after those two conflicts the United States Army started with the process of rebuilding the broken army6 examining the reasons of snuff iture in those two conflicts and drafting lessons learned from them in order to improve negative sides and to sustain those good sides. After those two conflicts the morale, discipline and reediness of the US Army were lower and even worsened than at any time in 20th Century and probably in the history of the United States Army. The Army leadership started with training and doctrinal neaten and finally the adaptation of Field Manual 100-5 Operations, during 1976 was some kind of wake-up call for the Army. Even though the FM was widely criticized it brought the fundamental change in the way how army should see itself in a fight, in addition, the FM was a tr ansition step that opened an intellectual dialogue across the Army.7 Later on this FM was revised in 1982 and 1986 introducing and refining the Air Land Battle and soon after this concept will be proven during the Desert wedge campaign.Operation Desert Storm was turning moment and can be used as a first example how the United States developed an American way of war based on technology, an air power, usage of precisely command ammunition (PGA), unmanned aerial vehicles (UAV), SOF and combine arms maneuver along with other enablers in order to defeat adversary forces for a short period of time and to achieve decisive victory. This operation was pure combination of combined arms maneuver supported by an air, maritime, and ground fire power, and can be connected to the traditional, firepower-intensive mode widely used during WW 2. The ground operation started with monolithic armored assault, after more than five weeks of precise bombing from air, land and sea guided by Special Operat ions Forces. During this operation the US Army adopted and proved the American Way of War, seeking a victory while having minimal casualties. The characteristics of new way of war were speed, maneuver, flexibility, and surprise, supported by clearcutness firepower, SOF, and psychological operations. The integration of air, ground and naval power into one synchronized matrix was more successful than the most optimistic predictions.8Operation Enduring granting immunity is second example to explain the United States, or American way of war, based and highly dependent on technology, an air power, PGA, UAV, SOF, combined arms maneuver, and other critical enablers such as sustainment which is required for successful conduct of war. Also this operation showed ability to conduct the combined arms maneuver and to sustain operations in hostile environment such us terrain, extreme temperatures and poor infrastructure. Carefully examining terrain and the experience of the USSR during invasion of Afghanistan, the US Army did not fail into the same trap pouring ground forces into the country, and instead of making the same mistake, the US Army decided to fight with the Special Operation Forces and massive usage of precision guided-ammunition. Additionally, the SOF established connection with the Northern Alliance and provided support to fight Taliban regime. After two months of fighting Taliban regime collapsed and operation Enduring Freedom succeed. From the other side, small amount of ground forces at the beginning of operation could not cover escape routes from Afghanistan, and Osama bin Laden escaped Afghanistan with other top terrorists.9The operation Iraqi Freedom was even more successful compering with war in Afghanistan, and during this operation the United States Army, together with coalition forces, conducted truly combined-arms operation. Compering the numbers, Coalition forces deployed less than one-half size of units deployed during operation Desert Storm, an yway, it did not stop them to conquer al entire Iraq for a precise short period of time with one-third of casualties and one-quarter the cost compering with the first operation. One more time the United States Army demonstrated ability to incorporate an air, sea and ground fire-power with combination of surgical strikes guided and conducted by Special Operation Forces in order to shape the battlefield for major operation. The Iraqi Forces deployed more than 450,000 troops in order to defend Iraq, it was not enough not only to slow down, but also to stop advance of Coalition Forces led by the United States Army. Doctrinally, the attacking forces must generate 3 to 1 force ratio to be successful, and if operation is conducted in difficult terrain or urban areas, the ratio goes up to 6 to 1force ratio. In this eluding the Coalition forces had more than 3 to 1 disadvantage in numbers, anyway it did not stop them to achieve remarkable victory in a very short period of time. One more time the United States Army proved that the combined arms maneuver, supported with all the available enablers, is if not the only way, than definitely one among few possible ways how to conduct future military operations regardless the scale of operations, units and enablers.10ConclusionAfter WW 2, the United States of America conducted several military operations and limited wars from Korea to Afghanistan and Iraq, and over the time has developed distinguished way of war based and highly dependent on technology and other enablers such us air, naval and ground support discussed in this essay. Additionally, the United States Army uses every opportunity to analyze and conduct an after live up to reviews in order to derive lessons learned and to improve conduct of military operations. Also, ability to sustain military operations, regardless of time, differentiate an American way of war from other nations and their armed forces.So whatAs LtC Steed described definition of winning as win ning is enhancing or improving interests and influence.11 The only thing, or Big So What from this essay that I will take away is The United States Army in case of war can bring to bear more than other countries can dream about. I would argue that having the United States of America as a true partner and friend can be really beneficial, especially for smaller countries such as Bosnia and Herzegovina. We already gained a lot benefits having The United States as friend and partner and hope to improve and strengthen our relationship in the near future. At the end I would like to mention that the World would be different without presence of The United States as leader in a free democratic world.Referenceshttps//www.foreignaffairs.com/articles/united-states/2003-07-01/new-american-way-war2 Ibid3 H307 Rebuilding a Broken army, reading H307RA, The Collapse of the gird Forces, by Robert D.

The Use Of Market Research Marketing Essay

The Use Of Market Research Marketing Essay cosmosThe use of merchandise query is essential to tradeplaceers as it is a descriptive and diagnostic tool that every(prenominal)ows marketers to understand the complexities of the market. It forms a very important comp one and only(a)nt of market strategy and solving specific market troubles. The use of both valued and qualitative question rules results in decisions that give notice take the form of marketing plans and strategies. These results in conclusion influence the outcomes of strategic marketing decisions and outcomes that match the marketing goals. The application of these two search methods have different uses as decimal research methods chargees on statistical entropy and in which surveys and questionnaires be commonly used. Qualitative research methods focus on the reasons cornerstone behaviours much(prenominal) as why and look to target the attitudes and emotions behind the behaviours that quantitative resea rch often shows ,with focus groups and interviews often being used. The results from these methods are often linked to the practical use of research methods as results can spay depending on the size, quality, type of method and the skill of the practitioner. The roles of these two research methods and their practical application in decision validated results in market research leave alone be supported below finished journal articles and references, which will further show the importance that the effective use of market research methods in discordant situations is essential in finding valid results that are fundamentally important to marketers today.Overview of research methods and their usesTraditional methods of market research often focused on quantitative results and practices, which although were adequate in finding valid research results, could not adapt well to the changing market and business environments during the 1950s and 60s and in turbulent market situations at the time. It was clear that research methods needed to be improved and as noted in Wilson (1952), The application of qualitative methods would allow a much conscious opinion to be gathered on the market, which would be well meet to the changing market situations at the time. Despite the value that qualitative research can bring, there is still a general trend in the dominance of Quantitative methods used by marketers and even in academia where qualitative methods are seen by some with ambivalence and a field with which booming people do not want to be associated with. Ruyter Scholl (1998). Due to this prevailing dominance among marketers, about market research carried out by contemporary organisations usually is a triangulation or combination of primarily quantitative techniques with some secondary qualitative methods to escort the research results. Ruyter Scholl (1998). Qualitative methods are best used when conducting exploratory research, when businesses need to understand th e behaviour of consumers and formulate ideas and theories as to why consumers think in event ways. To substantiate qualitative results, Quantitative techniques are used to provide hard evidence behind these ideas and theories and to represent numerally and statistically the resulting research outcomes. Not all marketers however triangulate these techniques and most will only use a methodology which is most appropriate in solving the research problem.Effectiveness in finding valid research resultsWhile both these methods have uses in finding valid research results, the variation in defining the research problems passim various organisations means that the most appropriate methodology and research design should be used to ensure valid results , rather than results that would lack meaning through with(predicate) a bias in using a particular research method. As pointed out in Seymour (1989) , research techniques and their thoughtful application can be the vehicle by which we progre ss to wisdom. That is, the real worth of a technique is embedded in its ability to produce useful information (i.e., wisdom) in solution to a specific problem. Seymour (1989). To ensure that results from market research is valid , a triangulation of methods and techniques should be considered and applied to the research of relevant markets and situations which would ensure results that are both valid, and winder a clear picture of the market environment. This triangulation of methods successful use in finding valid results is seen in Kitchell (1995) where the field conducted attempted to find the links amid the importance of a strong corporate culture and the adoption of new technology in conjunction with the issues faced with maintaining a competitive position. This was undertaken with both quantitative and qualitative research techniques. Both methods results were broadly consistent with each other in finding that fostering a stronger corporate culture allowed a more stable in novation and technology adoption which led to long term survival and adaption in market environments. This study has shown insights into how both qualitative and quantitative data can mutually enrich each other in market research as this triangulation of methods allowed valid research outcomes that would not have been seen if only one research method was primarily utilized. The results seen in this study correlate with those undertaken by Deshpande (1983) which explains that more valid results can be seen in market research with a combination of aspects between quantitative and qualitative methodologies. While using a triangulation of methods, the weaknesses and strengths of each technique would be compensated by the strengths of the other method. Deshpande (1983). Although using a triangulation of methods can typically produce valid and meaningful research results, extensive use of these techniques can be limited to firms with considerable budgets than most. To ensure effective res ults, defining the research problem and identifying the circumstances to which further research is needed is just as important as choosing the most effective methods suited towards the market environment. outline in Goodman (1995), the use of Qualitative techniques can be well suited to system construction and exploratory market research, which can be seen in his resultant study of small businesses in a changing market environment. In a study of three small businesses facing changing market conditions and uttermost(a) price erosion, qualitative research techniques were man-sizedly employed to determine achievable market strategies. It found that the exploratory nature of their research conducted through focus groups and judiciousness interviews, allowed them to anticipate changes in customer-value perceptions and benchmark themselves against competitors. This successful use of qualitative techniques in this study shows that this methodological approach was particularly well su ited towards finding and generating theories in a changing market environment, which was noted preceding(prenominal) in early qualitative research literature in Wilson (1952). In finding valid results through various methods, it is clear that marketers must not confine themselves through techniques that are only partially appropriate in solving the research problem. The studies noted above successfully found valid results as a result of their methodologies being used effectively due to the nature of the research problem and their applicability in these situations. til now as noted in Cahill (1996) , both qualitative and quantitative methods do not have universal applicability and as such, either method might not be suitable for a variety of situations. This means that marketers who entirely use methods of theory verification (quantitative methods) almost exclusively in situations where theory discovery (qualitative methods) was more appropriate, Deshpande(1983), are limiting the v alidity and reliability of their results by not applying the most appropriate method in solving the research problem .An effective use of market research techniques would be by triangulating aspects of research methodologies and also the choice of a specific technique on whether a quantitative or qualitative method should be decided by the nature of the management and research problems. Seymour (1989).This would eventuate in valid and meaningful results that serve to serving the marketer understand the needs of the consumer and market.Limitations of Research methodsWhile both quantitative and qualitative methods have their established uses among marketers, the limitations of each method in finding valid results can be reflected in the essence of these methods. As the quantitative paradigm is firmly placed within the scientific model, the resulting research outcomes are limited to numerical data that can be quantified and summarized into objective hard data. Results gathered by this particular method emphasise reliability and validity, which makes this a dominant method that marketers commonly use throughout the research process. Because of these factors that make up the essence of quantitative research, the use of this method in finding valid research results is limited to formalize established theories and the relationships between variables, but also can substantiate qualitative results through a triangulated methodology. Results accumulated from quantitative research are not suited towards theory generation and gaining insight and as such, marketers solely employing this method will miss out on the value that qualitative methods can bring. However, when involved in research that does not need as much insights or deeper data into defining the research problem, quantitative methods can be effective in analysing colossal amounts of data as outlined in Montgomery (2001). A successful application of quantitative methods was seen when solving internet marketin g problems outlined in this study however the skill of the practitioner in conducting the research was commonly cited as the factor that allowed valid research outcomes. While this study demonstrated a successful primary use of quantitative methods, the limitations of using qualitative methods in defining the same research problem would not be practical as analysing large swathes of data is not an effective use of qualitative methods. This contrast between both quantitative and qualitative methods, reflect the limitations of solely using one of these methods as the nature of the results produced from each will be fundamentally different. As discussed in Johansson Nonaka(1987), many Japanese market researchers during the 1980s much preferred research that was hands-on and interactive with consumers , and favoured qualitative data which allowed them to gain a distinctive feel for the market. While these qualitative methods lacked the scientific precision of quantitative methods, Japa nese firms still had an straightforward advantage over western based firms as their exclusively qualitative and hands-on methods allowed them to understand consumer behaviour to the point where they were outstripping rival western based firms. However like most western firms looking to increasingly adopt qualitative methods into their research, the Japanese firms are realising that in order to diversify their product ranges in the market they will need to use quantitative methods to ensure entries into newer markets. Johansson Nonaka (1987). This focus on one methodological approach by the Japanese firms, coupled with their extreme focus on their existing products, can represent limitations into finding valid results as their narrow approach would disallow much confirming or validation of theories attain from their qualitative research, especially when entering new markets. Despite these limitations, it can be argued that the Japanese approach to market research allowed them to u nderstand consumer behaviour in such a way that they were able to achieve valid research results even more reliable than western based quantitative methodologies. The limitations of both methods in finding valid results for marketers, has clearly shown that to overcome the relative weaknesses inherent in each method, an effective use of triangulated research methodologies is essential to finding valid research results.ConclusionsAs evidenced above, valid results in marketing are commonly seen with a triangulation of methodologies and techniques which pertain to the nature of the research problem. The limitations of both quantitative and qualitative methodologies can be compensated by using a triangulated research process, in which the weakness that is evident in each method will be overcome by the strengths of a triangulated methodology. However, marketers dominant use of quantitative methods in their research to which can be only partially appropriate in solving a research problem, serve to limit the reliability for research results that could otherwise be improved through a triangulated methodology. Likewise, it can be said that the dominant use of qualitative methods by Japanese firms could be further enhanced by the integration of quantitative methods into their research which serves to ease the entry into newer markets. The market environment and the nature of the research problem can also affect research outcomes as the method employed can only be somewhat relevant to the nature of the research problem, in which inadequate results may be seen. Furthermore, it is evident that to ensure valid results in market research, it is recommended that a triangulation of methods be used in the most applicable nature of the research problem and environment.

Home Appliances Control Using RF

Home Appliances Control Using RFThe visualize HOME APPLIANCES CONTROL USING RF is an alternate of the meditate make by human like switch on/off by hand. Here job of doing on/off can be done by from a distance by help of remote.The ckt. Consists of four parts. These are listed below-Power supply of 5v and 9v-it consist of ic 7805,7809 , two transformer, capacitors and diode.Micro governler-it consists of m/c AT89S52 , re frame ckt.RF module-It consists of ic HT-12D AND HT-12Erelay part-two ralays, two diode,two bulbsref.(1)HISTORYIn this rf ground project our information to control home appliance is send from remote to control them, here exploiter only have to press the switch of remote.In other words, one could remotely turn on light in ones lawn or the air conditioning at home, or turn on/off the light of room by help of remote sitting at one palace in home,The operation cost and power required is also less.METHODOLOGYIn this project our predict is transmitted through air fro m RF transmitter to RF receiver, which decoded the signal received, nonedecoded signal is send by 4 line to microcontroller.Microcontroller do the work on received selective information according to programming, which will turn on/off the relays, because bulbs are also on/off.BLOCK platFig.1Ref(5)CIRCUIT DIAGRAMFig. 2Ref(5)Fig. 3Ref.(5)WORKINGThere are two power supplies one of 5v and second of 9v. Power supplies are made by bridge wave rectifier. For making 5v supply we use 4doide, one capacitor of 470 micro F, ic regulator 7805, similarly the second power supply. 5v supply is inclined to AT89S52 and 9V to operate the relay.Firstly the rf signal is generated by ic HT-12E and transmitted through air by help of rf transmitter module, the received data is now decoded by rf ic HT-12D and send to microcontroller to work on it. Some connections are made be ready the functioning of both ics. When signal is decoded by ic HT-12D it gives output by its pin no. 10 to 13.These output lines feed to m/c to pin no. 10 to 13 to make the m/c in action close to connection are made as shown in fig of ckt.(Reset ckt. At pin no. 9, oscillator of value 11.0592 at pin no. 18 and 19 and power at pin no 40) Now, push button of remote is pressed by user then m/c do low or high to the pin no p2.0 and p2.1 output line from m/c connected to bakshis 122 base. These are high power transistor whose base is connected to to pin no p2.0 and p2.1 of m/c through resistance. If high power is given to pennant than it will be on due to which the relay make the connection between 3 and 4, and bulb be on. If low is at base of breath then TIP will not work and connection of relay will be 3 and 4 due to which bulb be off.So we can do on/off the home appliance by help of remote.In our project one bulb be on by pressing button 1, second by help of 2, both will be on by button no. 3. And both will be offed by button no. 4.Ref.(6)APPLICATIONBy using home appliance control using rf we can control a ll the galvanic devices of a home with the help of remote. We can on/off the devices by a distance.With the help of this concept we can make a robotic hand to wangle the objects which a far away from us.With this we can also design car whose motion can be controlled by a remote. For a specific front end of car we will define a specific command for forward movement we will press button no. 1 for backward button no. 2 for left by help of button no. 3 and right by button by help of button no. 4Other applicationsBurglar alert systemSmoke and fire alarm systemGarage door controllersCar door controllersCar alarm systemSecurity systemCordless telephonesOther remote control systemsRef(5)PROBLEMSWhile controlling home appliances using RF we have to face some following problems-We have use it to a particular range abt. of some meters not in range of kilometer or more distance.If m/c hanged we want to do on/off the switch then we are not confirmed abt. its on/off states.CONCLUSIONThis proj ect is very useful for electricity saving purpose. Because we can do on/off the switch very quickly, otherwise due to laziness we avoid to on/off them. show can easily be employ by any one because to use this project one should not need to learn any exceptional things and this project is very economical due to its simple circuit and by use of cheap components.COMPONENTS LIST attendant no.ComponentSpecificationsQuantity1Transformer1amp,12v12Regulator780513Regulator14Transformer1amp,9v15TIP 12226DiodesIN 4001N87RELAY28MICROCONTROLLERAT 89S5219HT-12D110HT-12E1COMPONENT DETAILSMICROCONTROLLER AT89S52-Fig. 4 ref(3)The Intel AT89S52 is a Harvard architecture, single cut out microcontroller (C) which was developed by Intel in 1980 for use in embedded systems. It was popular in the 1980s and early 1990s, but today it has largely been superseded by a vast range of enhanced devices with AT89S52-compatible processor cores that are manufactured by more than 20 independent manufacturers incl uding Atmel, Infineon Technologies, Maxim Integrated Products (via its Dallas Semiconductor subsidiary), NXP (formerly Philips Semiconductor), Winbond, ST Microelectronics, Silicon Laboratories (formerly Cygnal), Texas Instruments and cypress Semiconductor. Intels official designation for the AT89S52 family of Cs is MCS 51.Intels master AT89S52 family was developed using NMOS technology, but later versions, identified by a letter C in their name, e.g. 80C51, apply CMOS technology and were less power-hungry than their NMOS predecessors this made them eminently more suitable for battery-powered devicesImportant propertys and applications-It provides many functions (CPU, RAM, ROM, I/O, interrupt system of logic, timer, etc.) in a single big bucks8-bit data bus It can access 8 bits of data in one operation (hence it is an 8-bit microcontroller)16-bit address bus It can access 216 memory locations 64 kB each of RAM and ROMOn-chip RAM 128 bytes (Data Memory)On-chip ROM 4 kB (P rogram Memory)Four byte bi-directional input/output portUART (serial port)Two 16-bit timersTwo-level interrupt precessionPower saving modeA particularly useful feature of the AT89S52 core is the inclusion of a boolean processing engine which allows bit-level boolean logic operations to be carried out directly and efficiently on internal registers and RAM. This feature helped to cement the 8051s popularity in industrial control applications. Another valued feature is that it has four separate register sets, which can be employ to greatly reduce interrupt latency compared to the more common method of storing interrupt background on a stack.The AT89S52UART an be configured to use a 9th data bit that can provide addressable communications in an RS-485 multi-point communications environment.AT89S52 based microcontrollers typically include one or two UARTs, two or three timers, 128 or 256 bytes of internal data RAM (16 bytes of which are bit addressable), up to 128 bytes of I/O, 512 by tes to 64 kB of internal program memory, and sometimes a quantity of extended data RAM(ERAM) located in the foreign data space. The original AT89S52 core ran at 12 clock regular recurrences per machine cycle, with most instructions executing in one or two machine cycles. With a 12 MHz clock frequency, the AT89S52 could thus execute 1 million one-cycle instructions per second or 500,000 two-cycle instructions per second. Enhanced 8051 cores are now commonly used which run at six, four, two, or as yet one clock per machine cycle, and have clock frequencies of up to 100 MHz, and are thus capable of an even greater number of instructions per second. All SILabs, some Dallas and a few Atmel devices have single cycle cores.Even higher speed single cycle 8051 cores, in the range 130 MHz to 150 MHz, are now available in internet downloadable form for use in programmable logic devices such as FPGAs, and at many hundreds of MHz in ASICs, for example the net list from www.e8051.com.Common f eatures included in modern 8051 based microcontrollers include inbuilt reset timers with brown-out detection, on-chip oscillators, self-programmable Flash ROM program memory, boot loader code in ROM, EEPROM non-volatile data storage, IC, SPI, and USB host interfaces, PWM generators, analog comparators, A/D and D/A converters, RTCs, extra counters and timers, in-circuit debugging facilities, more interrupt sources, and extra power saving modes.Ref(3)PIN DIAGRAM-Fig. 5 ref(3)Pins 1-8 Port 1 Each of these pins can be configured as input or output.Pin 9 RS Logical one on this pin stops microcontrollers operating(a) and erases the contents of most registers. By applying logical zero to this pin, the program starts execution from the beginning. In other words, a positive potency pulse on this pin resets the microcontroller.Pins10-17 Port 3 corresponding to port 1, each of these pins can serve as habitual input or output . Besides, all of them have alternative functionsPin 10 RXD inci dental asynchronous communication input or Serial synchronous communication output.Pin 11 TXD Serial asynchronous communication output or Serial synchronous communication clock output.Pin 12 INT0 Interrupt 0 inputPin 13 INT1 Interrupt 1 inputPin 14 T0 Counter 0 clock inputPin 15 T1 Counter 1 clock inputPin 16 WR Signal for writing to extraneous (additional) RAMPin 17 RD Signal for reading from external RAMPin 18, 19 X2, X1 Internal oscillator input and output. A quartz crystal which determines operating frequency is usually connected to these pins. Instead of quartz crystal, the miniature ceramics resonators can be also used for frequency stabilization. Later versions of the microcontrollers operate at a frequency of 0 Hz up to over 50 Hz.Pin 20 GND GroundPin 21-28 Port 2 If in that respect is no mark to use external memory then these port pins are configured as universal inputs/outputs. In case external memory is used then the higher address byte, i.e. addresses A8-A15 will appea r on this port. It is important to know that even memory with capacity of 64Kb is not used ( i.e. note all bits on port are used for memory addressing) the rest of bits are not available as inputs or outputs.Pin 29 PSEN If external ROM is used for storing program then it has a logic-0 value every time the microcontroller reads a byte from memory.Pin 30 ALE Prior to each reading from external memory, the microcontroller will set the lower address byte (A0-A7) on P0 and immediately after that activates the output ALE. Upon receiving signal from the ALE pin, the external register (74HCT373 or 74HCT375 circuit is usually embedded ) memorizes the state of P0 and uses it as an address for memory chip. In the second part of the microcontrollers machine cycle, a signal on this pin stops being emitted and P0 is used now for data transmission (Data Bus). In this way, by means of only one additional (and cheap) integrated circuit, data multiplexing from the port is performed. This port at the same time used for data and address transmission.Pin 31 EA By applying logic zero to this pin, P2 and P3 are used for data and address transmission with no regard to whether there is internal memory or not. That means that even there is a program written to the microcontroller, it will not be executed, the program written to external ROM will be used instead. Otherwise, by applying logic one to the EA pin, the microcontroller will use both memories, first internal and afterwards external (if it exists), up to end of address space.Pin 32-39 Port 0 Similar to port 2, if external memory is not used, these pins can be used as universal inputs or outputs. Otherwise, P0 is configured as address output (A0-A7) when the ALE pin is at high level (1) and as data output (Data Bus), when logic zero (0) is utilize to the ALE pin.Pin 40 VCC Power supply +5VRef(4)REGULATOR(7805)-7805 is an integrated three-terminal positive wintry linear voltage regulator. It supports an input voltage of 7 volts to 35 volts and output voltage of 5 volts. It typically has a true rating of 1 amp although both higher and lower current models are available. Its output voltage is fixed at 5.0V. The 7805 also have a built-in current limiter as a safety feature.The 7805 will automatically reduce output current if it gets too hot. It belongs to a family of three-terminal positive fixed regulators with similar specifications and differing fixed voltages from 8 to 15 volts.The last two digits represent the voltage for instance, the 7812 is a 12-volt regulator. The 78xx series of regulators is designed to work in complement with the 79xx series of negative voltage regulators in systems that provide both positive and negative enjoind voltages, since the 78xx series cant regulate negative voltages in such a system.The 7805 is one of the most common and well known of the 78xx series regulators, as its small component count and medium-power regulate 5V make it useful for powering TTL.Fig.6Ref(5)REFEREN CESSearch Enginewww.google.com.Data Sheets from www.alldatasheet.comArticle on Password Based Security System on www.8051projectinfo.comData Sheet of Microcontroller from www.atmel .comArticle on Password based security system from Wikipedia.Text Book on 8051 Microcontroller (Mazidi)Text book on 8051 Microcontroller(Kenneth J.

The Code of Chivalry in The Once and Future King Essay -- Once and Fut

The Code of Chivalry in The Once and Future mogul T.H. Whites novel The Once and Future major power presents a code of chivalry that outlines the expected knightly behavior of the time. This particular code stresses loyalty to ones liege, love and honour toward women, and absolute devotion to justice. At the height of Arthurs kingdom, this code was widely accepted by all. However, as Arthurs kingdom begins to decline, the code of chivalry begins to hold less wideness among the people. The fall of Arthurs kingdom is directly related to the absence of the code of chivalry in the behavior of the Knights of the Round Table. Sir Lancelot betrays Arthur when he has an adulteress affair with Guenever. Sir Lancelot also disrespects women when he leaves Elaine to be with Guenever in Camelot. King Arthur himself is disloyal to justice when he allows Guenever to be rescued by Lancelot. The love triangle of Arthur, Lancelot, and Guenever is a constant theme end-to-end every account of the Arthurian legend. Geoffrey Ashes The Arthurian Handbook states that We may say that these knights are expected to serve their King...(81). The revelation of the affair finally comes when Sir Agravaine shouts, Traitor Knight Sir Lancelot, immediately art thou taken(White 569). Lancelot was summoned to Queen Guenevers bedroom, and Sir Agravaine is finally exposing the affair and gaining revenge on Lancelot for unhorsing him many times in the past. The two people that Arthur trusts most are Guenever and Lancelot. Arthur is tumesce aware of the affair between the two, but chooses to pretend that nothing is going on. Due to this naivety, Arthur earns the disrespect (and even hatred) of Agravaine and Mordred, who eventual... ...misuse of justice make way for Mordred and his ideas to take antecedent in Camelot. All of these actions eventually lead to Arthur chasing Lancelot and waging war upon him, while Mordred takes over in Camelot. This symbolizes that th ere is no middle ground between good (Arthur) and fell (Mordred). As good dissipates, evil always grows stronger. However, the same goes for evil dissipating and good rising to power. Given the time period in which T.H. White wrote (post World fight II), White is speaking of the downfall of Hitler and the rise of a new order in Europe. Works Cited Ashe, Geoffrey. The Arthurian Handbook.

The Minimum Wage Must Be Increased Essay -- Federal Minimum Wage

No family gets rich from earning the minimum plight. In fact, the current minimum wage does not even lift a family out of poverty.-- Jon Corzine Many flock can think back and remember what it was like to put in an application for that first job and be presented with a position. Taking that position represents maturity and is a very exciting time for a young person. All first jobs usually start with a minimum wage. Minimum wage is the minimum an employer has to leave an unskilled worker establish on the regulations set forth by the Fair Labor Standards cloak (FLSA) that was originally established in 1938. As people think back about their first jobs they can also remember what the minimum wage was when they took that position. Minimum wage is only increased based on the cost of life story from the prior year. If the previous year shows an increase then the minimum wage will increase in the coming sassy year. Sinegal (2009) stated The increase in the minimum wage is l ong overdue. Paying your employees well is not only the right thing to do but it makes for skinny business. Based on the cost of living we show for the year of 2009 minimum wage will not increase for 2010. Minimum wage is presently at $7.25 per hour. Most people who start at this rate ar young people who are in high school or college and are working a few hours to help pay for school. After they graduate they can apply for better jobs and move on. People who live in areas without growth, angiotensin-converting enzyme mothers trying to raise their children, and uneducated people are working more than one minimum wage job to make enough money to pay their financial obligations. While the cost of living did not increase, minimum wage is low because no increase is planned for 2010 a... ...years cost of living. What constitutes cost of living to the federal government and it that assessment being addressed fairly? Minimum wage is too low. The federal government must raise t he minimum wage so that the average American will not need to continue to work multiple jobs.ReferencesThe Department of Labor. (2010).
