Overview of Atlantic Spotted Dolphin

Atlantic spotted dolphins are active dolphins found in the Atlantic Ocean. These dolphins are distinctive for their spotted coloration, which is present only in adults.   Fast Facts About the Atlantic Spotted Dolphin   Atlantic spotted dolphins are 5-7.5 feet longThey weigh 220-315 poundsThey are often seen in the Bahamas and other warm parts of the Atlantic Ocean Identification Atlantic spotted dolphins have a beautiful spotted coloration that gets darker as the dolphin ages.  Adults have dark spots while calves and juveniles have dark gray backs, lighter gray sides, and a white underside.   These dolphins have a prominent, white-tipped beak, stout bodies, and a prominent dorsal fin.   Classification Kingdom: AnimaliaPhylum: ChordataSubphylum: VertebrataSuperclass: Gnathostomata, TetrapodaClass: MammaliaSubclass: TheriaOrder: CetartiodactylaSuborder: CetancodontaInfraorder: CetaceaSuborder: OdontocetiSuperfamily: OdontocetiFamily: DelphinidaeGenus: StenellaSpecies: frontalis Habitat and Distribution Atlantic spotted dolphins are found in the Atlantic Ocean from New England to Brazil in the west and along the coast of Africa in the east. They prefer tropical, subtropical and warm temperate waters. These dolphins are found in groups that may number more than 200 animals, although they are more often found in groups of 50 or less.   They are acrobatic animals that may leap and bowrider  in the waves created by boats. It is possible that there are two populations of Atlantic spotted dolphins - a coastal population and an offshore population. Offshore dolphins seem to be smaller and have fewer spots. Feeding Atlantic spotted dolphins have 30-42 pairs of cone-shaped teeth. Like other toothed whales, they use their teeth for grasping, rather than chewing, prey.  Their preferred prey are fish, invertebrates, and cephalopods. They usually stay near the ocean surface but may dive up to 200 feet when foraging.  Like other dolphins, they use  echolocation  to find prey. Reproduction Atlantic spotted dolphins are sexually mature when they are between 8-15 years old. The dolphins mate sexually but males and females are not monogamous.  The gestation period is about 11.5 months, after which a single calf about 2.5-4 feet long is born. Calves nurse for up to 5 years. It is thought these dolphins can live about 50 years.   How Would You Like to Talk to a Dolphin? Atlantic spotted dolphins have a complex repertoire of sounds. In general, their main sounds are whistles, clicks, and burst pulse sounds. The sounds are used for long and short range communication, navigation and orientation. The Wild Dolphin Project  studies these sounds in dolphins in the Bahamas and is even trying to develop a two-way communication system between dolphin and humans. Conservation The Atlantic spotted dolphin is listed as data deficient on the IUCN Red List. Threats may include incidental catches in fisheries operations and hunting. These dolphins are occasionally caught in directed fisheries in the Caribbean, where they are hunted for food.

Why Is Anti Gun-Control Necessary Essay - 713 Words

The banning of firearms in America is an illegal act, and degrades the values this country was founded on. They not only play a vital role in many peoples lives, but are useful tools, fun to use, and can protect people from harm. Our founding fathers wanted us to have them to protect ourselves from the government, and would be disgusted at our governments current abuse, and overall disregard of the constitution of the United States. A lot of people argue that guns kill people; this is untrue. Guns in the hands of a negligent person have potential to kill people, just as anything else. The statement ‘The Right to Keep and Bear Arms from the U.S constitution seems like a pretty solid sentence. There is really no way to misinterpret it.†¦show more content†¦However, modern times still seem to be very compatible with firearms. Guns have numerous uses besides killing your fellow man. Hunting is a big reason to own a weapon. Across the country, people hunt game; small and big. Some people might see this as a cruel act, but in most states the White Tailed Dear is amazingly overpopulated. Not many complain when you kill a cow to eat a hamburger, so it shouldnt be an issue to go hunting. People also enjoy shooting guns at targets. You can do long range sniping with rifles, shoot clay pigeons in the air with shot guns, or shoot targets with a hand gun. Each hobby is completely harmless, and enjoyable. Along with the recreational activities that firearms make possible, there is self defense. Lets face it - if youre in your home at night with an intruder in the house, who will act faster, 911 or a firearm in the hands of a trained user? The answer is obvious. In an emergency situation, a firearm is almost an essential. One might argue that the odds of you being held up in your own house are slim; well so are the o dds of a gun related death. If a gun user is properly trained, a gun can and would protect people in case of an emergency. In America, the outright banning of things that out of touch congressmen feel is harmful is all too common. For instance, if you take the year where the absolute MOST gun deaths occurred in America it would be 2003, and the number would be around 30,000.

Benefits of Higher Education Free Essays

The number of college graduates has recently been on the increase. Due to the increase of college graduates, there is a lot of competition in hunting for a Job. Many companies have been cutting back on hiring due to the slow down in the economy. We will write a custom essay sample on Benefits of Higher Education or any similar topic only for you Order Now When I think about what it takes to get a well-paying Job these days, one must be very knowledgeable about many different topics. This means companies are looking for people who can hit the ground running when they hire them. In addition to one’s knowledge they possess, a college diploma is very important while Job hunting. According to the essay, â€Å"Are they really ready to work†, mfoung people need a ange of skills, both basic academic skills as well as the ability to apply these skills and knowledge in the workplace. At the high school level, well over one-half of new entrants are deficiently prepared in the most important skills – Oral and Written Communications, Professionalism/Work Ethic, and Critical Thinking/Problem Solving â€Å"(Casner-Lotto, and Barrington, 2006, p. 51). Generally, there is a limit to what students can learn until they graduate from high school. The time spent in high school is not enough time to gain sufficient knowledge or skill to get a well paying Job. Additionally, high school is place where one learns a little about a lot of different things, receiving a general education. On the other hand, even if students have a college diploma, they still lack some skills, such as writing in English, written communications, and leadership, but they are better prepared than high school graduates. Especially, at the college level, students can concentrate on areas that they think they would want to work in the future, so they can get specialized knowledge and technology. Why do we need adequate skills? The essay â€Å"Work and Workers in the Twenty- First Century’ stated that â€Å"Automation will continue to displace low-skilled or unskilled workers in America’s manufacturing firms and offices† (Judy, and Amico, 1997, p. 234). In the twenty-first century, there is increased use of computers, robots, and automation in the workplace. This mechanization certainly has brought production costs down, but has lead to fewer unskilled Jobs available in America. The lost of these unskilled Jobs makes it more competitive for the unskilled labors, with not all unskilled labors able to find adequate paying Jobs. Therefore, the companies now require us to have brains. In addition, the physical labors are moving to second and third world countries, in order to build the groundwork for these developing economies. Studying at a college or university in the US these days, could cost tens of thousands of dollars annually including the student’s room and board cost. So after a 4 years of thousand dollars. These students must start paying their loans back shortly after they graduate. With employers not hiring and very limited Jobs available, these graduates have a difficult time findings Jobs paying the salaries required to pay their loans. Now, if tudents live with their parents, they do not have to pay for room, and board, but only tuition and material fees. Although the students college education is cost them less due to the fact that they did not have to pay for room and board, the cost of the education is still a big burden on most families. However, according to the essay â€Å"The Private Benefits of Higher Education†, there is a big difference between salaries for high school graduates and college graduates. â€Å"Among wage and salary workers between the age 25 and 34, median annual earnings were 58% higher for men who completed at least a achelor’s degree than for men who completed only high school ($42,341 vs. 26,842), but 92% higher for women who earned at least a bachelor’s degree than for women who earned only a high school diploma ($32,145 vs. $16,770; Perna, 2013, p. 451). † As stated above, men who received at least bachelor’s degree are able to earn more than one and half times more than the median high school graduate. Now as for woman, the numbers are even more pronounced than for the men with a women who earns a Bachelor earns about doubled than that of the median women with only a high school diploma. Research shows that parents with low income and no academic qualifications normally do not have a lot of information about how to get financial aid for their children. Job hunting is a highly competitive in the twenty first century. Moreover, mechanization and globalization narrow the workplace in the US. Therefore, although students have to pay a lot of money to go to a college or university, they still pursue college education. This is due to that higher education will be useful in order to find well-paying Job. In the next five years, college graduates will continue to increase more and more.

Concepts of International Relations free essay sample

Concepts in international relations Conjuncture In decision making in international relations, the concept of International Conjuncture, together with freedom of action and equality are important elements. Decision makers must take into account the set of international conditions in taking initiatives that would create different types of responses. Systemic level concepts International relations is often viewed in terms of levels of analysis, the systemic level concepts are those broad concepts that define and shape an international milieu, characterised by Anarchy. Power (super powers) Darkest blue countries most often considered to be superpowers, dark blue countries most often considered to be great powers, pale blue countries most often considered to be middle powers, and palest blue countries also sometimes considered to be middle powers. [2] The concept of power in international relations can be described as the degree of resources, capabilities, and influence in international affairs. It is often divided up into the concepts of hard power and soft power, hard power relating primarily to coercive power, such as the use of force, and soft power commonly covering economics, diplomacy and cultural influence. We will write a custom essay sample on Concepts of International Relations or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page However, there is no clear dividing line between the two forms of power. Polarity (international political structure) Polarity in International Relations refers to the arrangement of power within the international system. The concept arose from bipolarity during the Cold War, with the international system dominated by the conflict between two superpowers, and has been applied retrospectively by theorists. However, the term bipolar was notably used by Stalin who said he saw the international system as a bipolar one with two opposing powerbases and ideologies. Consequently, the international system prior to 1945 can be described as multi-polar, with power being shared among Great powers. The collapse of the Soviet Union in 1991 had led to what some would call unipolarity, with the United States as a sole superpower. However, due to Chinas surge of economic success after joining the World Trade Organization in 2001, ombined with the respectable international position they hold within political spheres and the power that the Chinese Government exerts over their people (consisting of the largest population in the world), there is debate over whether China is now a superpower or a possible candidate in the future. Several theories of international relations draw upon the idea of polarity. The balance of power was a concept prevalent in Europe prior to the First World War, the thought being that by balancing power blocs it would create stability and prevent war. Theories of the balance of power gained prominence again during the Cold War, being a central mechanism of Kenneth Waltzs Neorealism. Here, the concepts of balancing (rising in power to counter another) and bandwagonning (siding with another) are developed. Hegemonic stability theory (developed by Robert Gilpin) also draws upon the idea of Polarity, specifically the state of unipolarity. Hegemony is the preponderance of power at one pole in the international system, and the theory argues this is a stable configuration because of mutual gains by both the dominant power and others in the international system. This is contrary to many Neorealist arguments, particularly made by Kenneth Waltz, stating that the end of the Cold War and the state of unipolarity is an unstable configuration that will inevitably change. This can be expressed in Power transition theory, which states that it is likely that a great power would challenge a hegemon after a certain period, resulting in a major war. It suggests that while hegemony can control the occurrence of wars, it also results in the creation of one. Its main proponent, A. F. K. Organski, argued this based on the occurrence of previous wars during British, Portuguese and Dutch hegemony. Interdependence Many advocate that the current international system is characterized by growing interdependence; the mutual responsibility and dependency on others. Advocates of this point to growing globalization, particularly with international economic interaction. The role of international institutions, and widespread acceptance of a number of operating principles in the international system, reinforces ideas that relations are characterized by interdependence. Dependency NATO International Security Assistance Force in Afghanistan. Dependency heory is a theory most commonly associated with Marxism, stating that a set of Core states exploit a set of weaker Periphery states for their prosperity. Various versions of the theory suggest that this is either an inevitability (standard dependency theory), or use the theory to highlight the necessity for change (Neo-Marxist). Systemic tools of international relations * Diplomacy is the practice of communication and negotiation between rep resentatives of states. To some extent, all other tools of international relations can be considered the failure of diplomacy. Keeping in mind, the use of other tools are part of the communication and negotiation inherent within diplomacy. Sanctions, force, and adjusting trade regulations, while not typically considered part of diplomacy, are actually valuable tools in the interest of leverage and placement in negotiations. * Sanctions are usually a first resort after the failure of diplomacy, and are one of the main tools used to enforce treaties. They can take the form of diplomatic or economic sanctions and involve the cutting of ties and imposition of barriers to communication or trade. War, the use of force, is often thought of as the ultimate tool of international relations. A widely accepted definition is that given by Clausewitz, with war being the continuation of politics by other means. There is a growing study into new wars involving actors other than states. The study of war in International Relations is covered by the disciplines of War Studies and Strategic studies. * The mobilization of intern ational shame can also be thought of as a tool of International Relations. This is attempting to alter states actions through naming and shaming at the international level.

Should Marijuana Be Legalized Essays - , Term Papers

Should Marijuana Be Legalized? In this year of the millenium, the American populace, even while in the midst of the most prolonged economic boom in the history of the Republic, is confronted with some serious problems. Any randomly chosen group of people asked to list the most dangerous of these, would include among their immediate answers: The Drug Problem. By the Drug Problem, do they mean the proliferation in our communities of all illicit, mood-altering, physically dangerous drugs? Or do they really mean the accompanying problems bought on by these proscribed substances: crime and the threat of crime, violence, disease, the growing number of users on public welfare, the loss of productivity to the countrys industry, the congestion of the court system, the over-crowding of our penal institutions, the diversion of our tax dollars from more productive areas, the corruption of our law enforcement agencies, and directly and indirectly the erosion of our civil rights? Since I am confining this paper to discussing the laws prohibiting marijuana use, I will concede that it fits the first two categories above; i.e. it is by law, illicit, and by its nature, mood-altering. With the third category we enter upon shaky ground. There is no scientific proof that the prolonged use of marijuana exacts a greater physical toll on the user than the equivalent abuse of nicotine or alcohol. Under the name Extract of Cannabis, marijuana was once widely used medicinally in the United States, and still has minor medicinal uses in other countries. There is only one species - Cannabis Sativa - which yields both a potent drug and a strong fiber long used in the manufacture of fine linen as well as canvas and rope. The seeds are valued as birdseed and the oil, which resembles linseed oil, is valuable because paints made with it dry quickly. A Chinese treatise on pharmacology alleges to date from 2737 B.C. contains what is usually cited as the first reference to marijuana. Through out the history of man in just about every culture the mention of this substance is found used both as a fiber and a drug. The first definite mention of the marijuana plant in the New World, dates from 1545 A.D. when the Spaniards introduced it into Chile. The Jamestown settlers brought the plant to Virginia and cultivated it for its fiber. In 1762 Virginia awarded bounties for hemp culture and imposed penalties on those who did not produce it. George Washington was growing hemp at Mount Vernon three years later presumably for its fiber, though it has been argued that Washington was also concerned in increasing the medicinal or intoxicating potency of his marijuana plants. The argument depends on a curious tradition, which may or may not be sound - that the quality or quantity of marijuana resin (hashish) is enhanced if the male and female are separated before the females are pollinated. There can be no doubt that Washington separated the males from the females. Two entries in his diary supply the evidence. May 12-13, 1765: Sewed hemp at muddy hole by swamp August 7, 1765 - began to separate (sic) the male from the female hemp at do- rather too late. George Andrews has argued in the Book of Grass (1967): an anthology of Indian hemp that Washingtons August 7 diary entry clearly indicates that he was cultivating the plant for medicinal purposes as well as for its fiber. He might have separated the males from the females to g et better fiber, Andrews concedes but his phrase rather too late suggests that he wanted to complete the separation before the female plants were fertilized and this was a practice relating to drug potency rather than to fiber culture Brecher, Edward M. and the Editors of Consumer Reports Licit and Illicit Drugs 1st ed. Mount Vernon, New York: Consumers Union, 1972 The plant has many names: marijuana, hemp, ganja... The list is almost endless. To the ancient Hebrew it was Kaneh Bosm, a name that can still be found in the Hebrew version of the Holy Bible (Exod. chapter 30, verse 23; Isa. chapter 43, verse 24; Jer. chapter 6. verse 20; Ezek. chapter 27, verse 19; Song of Solomon chapter 4, verse 14).

AI in cyber Defense Essays

AI in cyber Defense Essays AI in cyber Defense Essay AI in cyber Defense Essay The speed of procedures and the amount of data to be used in defending the cyber space cannot be controlled by humans without significant automation. On the other hand, It is hard to develop software with conservative fixed algorithms (hard-wired logic on decision making level) for efficiently defending In opposition to the vigorously evolving attacks in networks. The applications of artificial intelligence an be used to handle this situation that offers flexibility and learning potential to software. A brief review of artificial intelligence applications in cyber defense, and analysis of prospects of enhancing the cyber defense capabilities by increasing the intelligence of the defense systems have been presented in this paper. After surveying the papers available about artificial Intelligence applications In cyber defense, we conclude that useful applications are already present. They belong to applications of artificial neural nets in perimeter defense and some other cyber defense fields. So it has become clear that only AY techniques can guarantee successful solutions to many cyber defense problems. For instance, use of extensive knowledge Is essential In decision making, and Intelligent decision support Is so far one of unanswered problems in cyber defense. 1. INTRODUCTION: 1 . 1. Background of Study. 1. 1. 1 . Limitations in cyber security that are need to be addressed. Cyber security Is a multidisciplinary field that Is targeted on reduction of risks to the secrecy, affinity and integrity of data, information and resources in computer as well as in network systems. Modern systems have become much complex. Need for an intelligent, adaptive and multimode solution raises here for which best suited approach is artificial intelligence. [l]. There was not apparently strong collaboration between cyber security and artificial intelligence in early days. Researchers of AY were paying attention In making computers do things that only humans had been able to do, while security researchers Intended to fix the leaks In examining the computing communications or design communications they consider leak proof. Further, AY researchers were often most interested in building systems with behaviors that could hangs over time through knowledge or adaptation, and hence were to some degree unpredictable. From the security point of view, volatile system behavior seemed unwanted. But the two fields have developed closer over the years, mainly where human users but also at lower system layers. [2] 1. 1. 2. Why has the role of intelligent software in cyber operations augmented so rapidly? Looking closer at the cyber space, one can see the following answer. Artificial intelligence is required, first of all, for swift response to various scenarios in Internet. One has to be able to handle large annuity of information very fast in order to portray and investigate events that take place in cyber space and to make essential assessments. The speed of processes and the amount of data to be used cannot be controlled by humans without significant automation but, it is hard to develop software with conservative fixed algorithms (hard-wired logic on decision making level) for efficiently protecting against the assault in cyber space, because new deterioration become visible continuously. Here is a place for artificial intelligence methods. [3] 1. 2. PROBLEM DEFINITION: Do some artificial intelligence techniques exist to improve certain aspects of cyber security? 1. 2. 1 . Remarks concerning the problem definition. The aim of the thesis is to determine whether the possibilities in artificial intelligence can effectively address some of the limitations in todays cyber security. Figure : Cyber Attack. 2. ABOUT ARTIFICIAL INTELLIGENCE: AY as an area of research is very old. It is equally old to electronic computers. There is possibility of building devices more intelligent than human beings from the early days of AY on the realm. The time realm moves away when time passes. A number of intelligently hard problems have been witnessed to be solved by computers like playing good chess. Chess playing was deemed a benchmark showing a real intelligence during the initial days of computer. Even in seventies of the last century, when the computer chess has reached on the masters level, it appeared almost impossible to make a program that could smack the world champion. However, this came about faster than estimated. Three reasons are important to mention here for success of chess computer: computing power has been increased, efficient search algorithms have been developed (that can be used in many applications beside chess, see the section on search below), and knowledge bases has been organized so well that they became able to include all available chess knowledge(first of all, opening and end games). In core, the chess problem could be solved because it was a specific intellectual problem which was related to professed narrow artificial intelligence. A special instance is translating from one language into another that Chamoiss work in structural linguistics, it was expected that the natural language translation problem will be solved soon. It has not happened yet, although success is evident in some specific applications like, for example, Googles AY linguistics. The reason is that this demand of artificial general intelligence possessing of an aptitude to handle large quantity of information in every field associated to human actions. It is usually acknowledged that AY can be considered in two manners: as a science intended at attempting to determine the fundamental nature of intelligence and emerging generally intelligent machines, or as a science providing ways for solving complex problems that cannot be solved without applying some intelligence eke, for example, playing good chess or making right decisions based on large amounts of data. [3]Len the present paper we will take the second approach, supporter for applying specific AY methods to cyber defense problems, and will refer to the existing AY algorithms described in [4]. . CHALLENGES IN INTELLIGENT CYBER DEFENSE: If we talk about the future research in development and applications of artificial intelligence techniques in cyber defense, we need to make a distinction between immediate objectives and long-term goals. Numbers of AY techniques are immediately applicable in cyber defense and a lot of problems are yet need to be dressed. We have talked about alre ady present immediate applications. One can expect encouraging perspectives of completely new principles of knowledge handling in situation management and decision making process. Proposed principles are introduction of a modular and hierarchical knowledge architecture. Expert systems are already being used in many applications, sometimes hidden inside an application, like in the security measures planning software. Still, expert systems can get wider application areas, if large knowledge bases will be developed. This will need substantial investment in knowledge achievement, and development of large dollar knowledge bases. Also further development of the expert system technology will be required: modularity must be introduced in the expert system tools, and hierarchical knowledge bases must be used. A futurist Ray Kurt well has extrapolated the development to come up with Singularity in 2045 [5]. One need not to believe in the Singularity threat, but the rapid development of information technology will definitely enable one to build considerably better intelligence into software in coming years. (Consider the recent impressive performance of IBM-s Watson program)[6]. Elementally of whether the GAG is available or Singularity moms, it is critical to have the ability to use better AY in cyber defense than the offenders have it. 4. PRESENT WORK OF AY IN CYBER DEFENSE: There are numerous useful applications available in the field of AY application cyber defense. They all belong to application of artificial neural nets in perimeter defense, and they are helping in solving many cyber defense problems. Wide knowledge usage is necessary in decision making, and the intelligent decision support is still to problem, which required human interference. We have grouped all AY methods and architectures in several categories like neural nets, expert system, intelligent agents, reach and machine learning. 4. 1 . Neural NetsNeural nets have long history that begins with the invention of perception by Frank Reasonable in 1957. Perception is an artificial neuron, and popular element of neural nets. Small number of perceptions combined together can learn and solve interesting problem. Neural nets consist of a large number of artificial neuron, which provides a functionality of parallel learning and decision making. They are suitable for learning pattern recognition, for classification, for selection of response to attack etc. They can be implemented either in hardware or in footwear. Neural nets are well applicable in intrusion detection and intrusion prevention. There have been proposals to use them in DOS detection, computer worm detection, spam, detection, zombie detection, mallard classification and in forensic investigations. The neural nets in cyber defense are popular because of their high speed, if implemented in hardware or used in graphic processors. There are new developments in the neural nets technology like third generation neural nets, spiking neural network that mimic biological neurons more realistically, and provide more application opportunities. Figure : Intrusion Alarm System. . 2. Expert Systemsalt is most widely used AY tools. It can be directly used for decision support, in cyberspace. An expert system includes a knowledge base where expert knowledge about a specific application domain is stored, it also includes an inference engine for deriving answers based on this knowledge and possibly additional knowledge about a situation. Empty know ledge base and inference engine are together called expert system. Developing an expert system means first selection of an expert system shell and second acquiring expert knowledge and filling the knowledge base with knowledge. There are many different knowledge representation forms in expert system, the most common is rule based representation. But the usefulness of expert system depends mainly on the quality of knowledge in the expert system depends mainly on the quality of knowledge in the expert system knowledge base. Example of cyber defense expert system is one for security planning. This expert system facilitates considerably selection of security measure, and provides guidance for optimal usage of limited resources. 4. 3. Intelligent agentslengthier agents are software components that process some torture of intelligent behavior that makes them special like protectiveness, understanding of an agent communication language (CAL), reactivity etc. They possess planning ability, mobility and reflection ability. Intelligent agents can consisting of mobile intelligent agents after solving some legal and also commercial problems. This will require implementation of infrastructure for supporting the cyber agent mobility and communication. This will require cooperation with Sips. 4. 4. SearchSearch is a universal method of problem solving that can be applied in all cases. Very little must be known in order to apply some general search algorithm n the formal setting of the search problem, one has to able generate candidates of solution, and a procedure must be available for deciding. The search is hidden in the software and it is not visible as an AY application. Search on and or trees, up-search, maxima search and stochastic search are useful in decision making for cyber defense. 4. 5. LearningLearning is improving a knowledge system by extending or rearranging its knowledge base or by improving the inference engine. Machine learning comprises computational methods for acquiring new knowledge, new skill and new ways to organize existing knowledge. Problem of learning fluctuates with respect to the complex from simple parametric learning which means learning values of some parameters, to complicated forms of symbolic learning, for example learning of concept, grammars, functions and learning of behavior. AY provides methods for both supervised learning as well as unsupervised learning. Data mining has originally grown out of unsupervised learning in AY. Unsupervised learning can be a functionality of neural nets, in particular of self organizing maps. Parallel learning algorithms are suitable for execution on parallel hardware. These learning methods re represented by genetic algorithms and neural nets. 4. 6. Video and CATV semantic analysis for terrorist or criminal action detectionA new generation of intelligent CATV cameras that can hear as well as see will alert police to crimes in progress by recognizing clues such as a person running or the sound of a scream. Researchers hope the smart cameras will have a dramatic impact on crime detection and prevention by cutting response times and ensuring that more incidents are caught on tape. The Daily Telegraphs Gordon Earner reports that a team at the University of Portsmouth has already developed software which enables Amerada to spot visual clues to anything from violent crime to vandalism, by looking for tell-tale signs such as someone raising their arm suddenly or even a snapped car aerial. This artificial intelligence software is now being taught to recognize sounds associated with crimes, including breaking glass, shouted obscenities, and car alarms going off. Cameras which hear the sounds will automatically swivel to the direction they have come from, and will alert the person monitoring the system to a possible crime progress. [7]. 5. ANALYTICAL CONCLUSION: The present situation of hastily growing intelligence of mallard and erudition of Weber attacks advocates that it is obvious to develop intelligent cyber defense methods. The incident of Dodos(Denial-of-service attack) alleviation has revealed that even a defense against large-scale attacks can be successful with relatively limited resources with usage of intelligent methods. An analysis of publications illustrates research in artificial neural nets. Applications of neural nets will continue in cyber defense. There is also an vital need for application of intelligent cyber defense systems in numerous fields where neural nets are not the most appropriate technology. These fields include decision support, situation awareness and knowledge management. Expert system technology is the most promising in this context. We are not sure about how rapid development of general artificial intelligence is ahead, but a threat exists that a new level of artificial intelligence may be used by the invaders, as soon as it becomes accessible. Clearly, the latest developments in knowledge understanding, representation and handling also in machine learning will significantly boost the cyber defense competence of systems that will utilize them.

Tourism Policy of West London Essay Example | Topics and Well Written Essays - 1000 words

Tourism Policy of West London - Essay Example At the same time, the sustainable tourism policy says local people are partners in the revenue of tourism because they have to maintain the culture and heritage of the place to make it an attraction. Developmental policy focuses on the ecological and financial development of the society. It is necessary to take this perspective while forming the policy as a socio-economic factor, development, tourism, and sustainability are all interlinked. In London, tourism supports the economy, and generates jobs. The important tasks detailed by the Mayor say it all. He reiterates that London's economy should continue to be successful and only then, could it be distributed. It is a long term sustainable success dealing with the climate change and its necessities. "All Londoners must participate in this success. Not only for social justice but because without it the quality of life in the city will deteriorate and the consensus for London's internationalisation will break down" http://www.lda.gov.uk/server/show/ConWebDoc.1886 It is possible to present a vision with the right perspective of development, cultural atmosphere and socio-economic parameters because they are the main factors that govern tourism and its development. Cultural background is necessary to develop, retain and to present as an attraction, while socio-economic parameters are necessary for benefit and improvement. Development of London with the impending Olympics cannot develop without a vision of its own. What is tourism visioning Provide an example of a vision statement from your policy document. (Note it may be necessary to read between the lines if this is not immediately obvious) Why is it necessary to undertake such an exercise Tourism visioning has the social and economic conditions of the region in mind, while keeping the cultural perspective intact. It is more of eco tourism that sustains the tourism industry, but maintains the eco balance of the state, by not harming the tourist attractions or the region in any way and it will also combat the global warming. The Mayor's vision of London tourism says: "To develop London as an exemplary sustainable world city, based on interwoven themes: strong and diverse, long-term economic growth; social inclusion to give all Londoners the opportunity to share in London's future success; fundamental improvements in London's environment and use of resources. A Prosperous City: Making London a more prosperous city with strong and diverse economic growth. A City for People: Making London a better city for people to live in. An Accessible City: Improving London's transport and making it accessible to disabled users, women, children and the elderly; making the most sustainable and efficient use of the space in London; encouraging intensification and growth in areas of need and opportunity" A Fair City: Promoting social inclusion and tackling deprivation and discrimination A Green City: Making London a more attractive, well designed green city" . It is necessary because London must have better economic growth to remain a prosperous city and it has to remain eminently habitable without any adverse effects of tourism. It should be internally and externally suitably linked for all
