If Every Person in the World Understood Basic Principles of Psychology, the World Would Be A Better Place

Introduction Psychology is a broad aspect that entails the study of the soul, mind and behavior of organisms especially in human beings. Psychology helps in describing an individual’s behavior and also explaining the reasons why he or she behaves in a specified manner.Advertising We will write a custom essay sample on If Every Person in the World Understood Basic Principles of Psychology, the World Would Be A Better Place specifically for you for only $16.05 $11/page Learn More ‘‘Psychology studies the various activities of man, both bodily and mental that he performs while dealing with the environment of objects and persons’’ (Mohsin 3). It also allows for prediction of how a certain behavior could be affected by some changes as well as controlling and improving behavior through the application of the changes in an appropriate manner. The word psychology comes from Greek roots, psyche and logos meaning mind and study res pectively hence it’s the study of the mind[1] (Nevid 4). There are many principles that make up the psychology field some of which are general while others are specific to the particular branches of psychology. This piece of work gives an insight of the importance of the principles of psychology in our day to day life and how they can help make the world a better place giving much emphasis on the areas of focus and schools of thought in psychology, the basic principles of psychology and their importance, the branches of psychology, how knowledge on psychology may be attained and their importance in enhancing people’s lives. Areas of focus and schools of thought in psychology ‘‘Psychology as a science has two major areas of focus’’ (Tsivkin 1)[2]. The two major areas are academic psychology and applied psychology. Academic psychology[3] is involved with the study of the various divisions or subtopics in the field of psychology. The subtopics ma y include personality psychology, developmental psychology, biological psychology, industrial psychology, health psychology, educational psychology and social psychology all aiming at broadening the theoretical understanding and knowledge of psychology among the learners. Applied psychology[4] on the other hand is broad and aims at solving the problems and challenges encountered by individuals in their day to day activities and practices. This is usually through the application of the various psychological principles and it is utilized in various careers for instance medicine, ergonomics, and forensics and industrial areas among others (Tsivkin 2)[5]. The are a variety of schools of thoughts in psychology some of which are; behaviorism psychology which focuses on behavior and learning and how they are affected by the environment, and psychodynamic psychology which studies the unconscious mental processes and explains the psychological behavior in human individuals in regard to the i nteraction of the conscious and unconscious processes.Advertising Looking for essay on psychology?

This focuses on the compound nature of subjectivity where there is dependence of knowledge and reality on the social relations and practices of human beings. Phenomenological or humanistic psychology on the other hand deals with the subjective and unique nature of events showing the meaning and importance of existence while cognitive psychology focuses on the processing, storage and retrieval of information processes in the human brain for instance perception and decision making( James 224). Physiological psychology focuses on the neurobiological processes and explains how they affect behavior and the processes of the brain. These are some of the existing schools of thoughts and others are yet to emerge as the field of psychology continues to grow (Tredoux, Foster and Allan 3). Basic principles of psychology and their importance The field of psychology is very wide and it has been faced with a lot of controversies due to the existence of a variety of schools of thoughts in it. There are however major similarities and differences among the different schools of thoughts. A school of thought entails an entity whose principles ought to be carefully studied, understood and related. The individual psychology entails the study of unique and undivided personality. Person uniqueness should be understood in relation to the others. This is a very important principle as it can help people to understand one another having in mind that we are all unique. It helps in tolerance and perseverance of one another’s behavior and also learning how to accommodate different personalities. There is also the principle of affinity which is expressed in the aspect of need f or achievement or attainment of some goals in human nature. An individual at any stage of life is always in motion, trying to meet a certain goal in life. The understanding of this concept helps us to understand the behavior of an individual and hence relate well as we get to know the reasons for a person’s behavior. â€Å"If we know where a person is going, we can understand why he is moving the way he is moving. In other words: we understand his behavior.† (Sophia 1). Creative ability in an individual is also very important and starts from childhood where a child looks for ways of survival and development and protection.Advertising We will write a custom essay sample on If Every Person in the World Understood Basic Principles of Psychology, the World Would Be A Better Place specifically for you for only $16.05 $11/page Learn More This goal determines ones feelings, actions and thoughts. A human being is a social being that is expected to cooperate with others but some people have some limitations and prefer living by their own and the understanding of this will help us deal with all kinds of people who behave in different manner. Reasoning is a crucial aspect of an individual as in allows one to turn negative into positive through reasoning and making choices. The choices we make out of possibilities lead us to different situations. Reasoning makes things easy. It is important to understand that being a social being, an individual can not live by his or her own but have to borrow some issues and values. This is a very encouraging aspect that ensures respect and appreciation for others and allows one to be responsible for him or herself and also for the sake of the others. The nature of man to strive towards perfection is also a concern. An individual should try to perfect his or her behavior and also accept his or her imperfection where changes cannot work. It is through the act of looking forward towards perfectio n and the acceptance of our imperfects that we improve our behavior and life in general. Branches of psychology and the importance of their basic principles There are various branches of psychology each having some basic principles. The branches include abnormal psychology, child psychology, physiological psychology, animal psychology and social psychology among others. Abnormal psychology is the study of the behavioral abnormalities that are experienced in the human mind. ‘‘It is not an accurate title. It should be termed psychopathology’’ (Dandapani 7). It involves aspects like mental retardation, depression, sexual deviation and neuroses. It helps identify the sources of the abnormalities and hence deal with the conditions appropriately. Some of the people involved with this work are the psychotherapists and psychiatrists, counselors and clinical psychologists. Child psychology also known as developmental psychology entails the factors that govern the de velopment of an individual through out the lifespan from the infant stage to adulthood. It emphasizes aspects like growth, development (mental, social, emotional, and physical) maturation and learning all which are the steps that a human being goes through in life explaining how and why people change their behavior over time. The principles in child psychology are useful in understanding human beings and most specifically to parents and teachers through the norms and tasks that are learnt for the various stages of development.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Animal psychology on the other hand, also regarded as comparative psychology is a branch of psychology that is involved with the study of animal behavior with an aim of having a comprehensive understanding of human psychology. It works under the principle that there some common factors in regard to human behavior and animal behavior although the aspect of thinking, speaking and imagining only apply to human beings and not to animals. The animals are used as subjects in experiments and the results compared to what could happen in human beings especially where persons cannot be used as specimen. Physiological psychology is the study of the physiological aspects that entail how we think showing the relationship between the operations of the brain and what an individual actually say or how he or she behaves. It tries to connect the brain with action and speech and other common senses. ‘‘Mind and body cannot be separated. Hence psychology and physiology are inter-related†™â€™ (Dandapani 8). Educational psychology is a branch of psychology that is concerned with educational issues, students concerns, schools and teaching psychology. The educational psychologists are concerned with the performances of the students and so they work closely with the people concerned for instance the students, parents, administrators and teachers to monitor and improve their situations (Cherry 1). All these branches of psychology are very essential and are applied in various fields of life to help solve problems that would otherwise seem difficult without the understanding of the basic principles contained in the different branches. Means of getting the knowledge of psychology and its help in personal lives People can attain knowledge on psychology through various means for instance through attending classes for example taking psychology courses in grade school, high school and even at colleges and university levels. The psychology knowledge can also be attained o utside class where the people with vast knowledge in psychology can educate the rest on the various aspects and principles of psychology that are relevant in our day to day activities and practices. Written documents on psychology would also offer a good base on psychology knowledge that could be applicable in human beings life for example in problem solving. The internet has also a wide range of information on the different perspectives in the field of psychology and could therefore be used as a tool through which information and knowledge on psychology could be attained. Irrespective of the means through which the knowledge is attained, the important thing is the utilization of the knowledge in our lives as we are in a better position to understand human nature and behavior and hence live positively with each other despite our differences. Psychology is very essential in our daily life irrespective of our careers or fields of specialization and its existence can not be ignored or under emphasized. The following are the ways through which the knowledge of psychology can be applied to enhance our personal lives. Psychology keeps us motivated in our understanding as it offers tips of motivation for instance from the cognitive and also the educational psychology. ‘’Whether your goal is to quit smoking, lose weight or learn a new language, some lessons from psychology offer tips for getting motivated’’ (Cherry 1). It advocates for application of new elements in our activities to boost our interest, vary the sequence to avoid boredom, learning new aspects to boost knowledge on an issue, establish clear and achievable goals in regard to the specific task, and rewarding one self for any achievement. Motivation is very important as it helps keep human beings on the move and not to despair. Psychology also enhances an individual’s leadership skills which are very essential in every one’s life. ‘‘It doesn’t ma tter if you’re an office manager or a volunteer at a local youth group, having good leadership skills will probably be essential at some points.’’ (Cherry 1). Though not all people could be leaders naturally, skills and knowledge learnt from psychology could promote leadership abilities in individuals. Some of the tips could be offering guidance and listening to others, and being positive and creative. Psychology also helps individuals to understand each other through the understanding of ones emotions and those of others which in return strengths relationships between people. This is because the emotional intelligence quotient of a person who has some knowledge on psychology is higher as compared to that of a person who has less or no knowledge in psychology. Psychology also enhances the process of decision making. The principles in cognitive psychology allows for better decision making through consideration of aspects like application of various perspectives o r points of view for instance the positive and negative sides of the issue, consideration of the benefits and challenges associated with the decision and finally gauging the results that could be attained after making the decision. Psychology is also a tool that enhances personal communication especially nonverbal communication. ‘‘Communication involves much more than how you speak or write’’ (Cherry 1). This is because psychology helps us to express ourselves through non verbal signals and most importantly to read and understand the non verbal signals of others hence know how to behave or act on different situations. It for example teaches on the importance of good eye contact that allows identification of nonverbal signals of those around us and also the importance of tone of voice in delivering message. Knowledge on psychology is also essential in ones health. ‘‘Psychology can also be a useful tool for improving your overall health’â⠂¬â„¢ (Cherry 1). Health psychology in particular advocates exercises and proper nutrition to avoid health issues like depression. It is also through the study of psychology that we are able to understand the working of an individual’s body and mind and hence understand various behaviors exhibited by different individuals in different situations. People avoid complication of issues which could otherwise affect ones health negatively for example through depression. ‘‘They are going to avoid things that can cause stress, they are able to manage time very well, and more effectively with their studies or chosen career.’’ (Phillippe 1) Importance of the knowledge of basic principles of psychology in work places and the economy at large From the above discussion we can conclude that psychology is very important and can be applied in almost all aspects of life including the work places and also in the activities that are geared towards improving or developi ng the economy. The ways in which the knowledge of psychology can be utilized in enhancing personal lives as discussed above can also be carried on to the workplaces. This is for instance in critical and informed decision making, proper interaction with workmates and clients, proper or effective communication, being motivated to work hard and never to give up, and also being good leaders. Psychology also assist in wiser financial decisions in the work place as it teaches on financial management tips such as investing in savings, and avoiding poor choices in regard to money spending. It also promotes individual and group productivity through instilling tips like avoidance of multitasking especially when handling complex or involving tasks, and being focused towards a particular task and doing away with distractions under all circumstances. It is also through the study of psychology that we are able to have a better understanding of the functioning of the body and mind of a person hen ce deal with different behaviors exhibited by different people at different situations better and also build proper and working personal and work related relationships through enhancing self knowledge and understanding on others and in the long run, making ones personal and working life better. Psychology has also proved to be a significant tool towards enriching careers. This is achievable since when an individual knows and understand the other workers well including their uniqueness and personality, he or she is able to interact and get along well and most importantly know how to behave knowing what experiences they are going through and being careful not to make their situations worse through their behavior. Conclusion From the research, it is evident that the study of psychology is very essential in our understanding of human behavior through things like feelings, emotions and thoughts and in a way the understanding assists us in our day to day interaction with different people. Psychology is however very broad making it difficult for one to comprehend all the aspects but specialization and understanding of some basic principles is very essential. There have been a lot of changes and developments in psychology as psychologists engage in advanced and objective approaches in the search of knowledge with an aim of getting full understanding of the human behavior. New ideas and theories are also emerging as the psychologists combine the various aspects and beliefs in the different schools of thoughts in making their conclusions on various aspects that entail human behavior. All in all the importance of the knowledge of psychology is very useful in our day to day activities due to the positive impacts it has on both personal life and also in regard to integration with others for example family members or even co-workers and clients in the working place.

The Great Gatsby Essays

The Great Gatsby Essays The Great Gatsby Essay The Great Gatsby Essay The Great Gatsby as a description of the failure of the American dream. The Great Gatsby is a concentrated meditation on the American dream, understood as the faith that anyone, even of the most humble origins, can attain wealth and social standing in the United States through talent and individual initiative. Fitzgerald explores the compelling appeal of this dream, and the circumstances that render it as deceptive as it is enduring. Fitzgeralds protagonist is a young man from North Dakota, James Gatz, who changes his name to Jay Gatsby and manufactures a persona out of his own Platonic self-conception. While in his soldiers uniform just prior to service in World War I, Gatsby falls in love with Daisy, a beautiful, rich young woman whose voice has the sound of money. After the war, Gatsby pursues Daisy, even though she has by then married a gruff and tasteless man of her own class. Gatsby buys a huge, garish mansion on Long Island near Daisys home and tries t o impress her and her social set with lavish parties financed, as some of his guests rightly suspect, by the illegal sale of alcoholic beverages. But Daisy rejects Gatsbys suit, as her feelings and behavior are controlled by the conventions of her class in ways that the innocent American dreamer does not understand. In the end, it is inherited wealth and social standing that determine much more of ones destiny than is determined by talent and individual initiative, readers of The Great Gatsby are led to conclude. Much of the power of The Great Gatsby derives from Fitzgeralds having provided readers with an opportunity to simultaneously see through the pretenders illusions and identify deeply with his aspirations and even love him for having made the effort. Nelly, on the other hand, is considered to be far more worthy narrator because of her close association with Heathcliff having grown up with him and her honest, occasionally blunt opinion. An example is where Nelly asks Catherine Why do you love him? (referring to Edgar Linton) and then proceeding to say Bad! to her replies. This could be construed as a breach of etiquette in the nineteen hundreds for a servant to speak so to a lady of higher station and demonstrates Nellys ability to speak her mind which endears her to the reader. As a result of this fact it is Nelly who undertakes the conveying of the tale of Wuthering Heights and to whom we look for our opinions in other characters. She is, in fact, a narrator within a narrator due to her recounting of the tale of Wuthering Heights to Lockwood for entertainment and both tells the story and yet features heavily in its events. Fitzgeralds narrator, Nick Carraway is young, thoughtful and intelligent. He has moved from the West in favour of the fake and unproductive society of New York which he ultimately rejects. The landscape to which he moves is unproductive due to the fact that it grows or produces nothing dealing only in stocks and shares a world that Nick unsuccessfully immerses himself in. The world into which Nick ventures could be accurately captured by Fitzgeralds description of Daisys voice being full of money . He is also considered to be truthful in regard to his views on other characters. This impression is given to us by the words: I am one of the few honest people that I have ever known. A self-confession giving vital information to us this being that what Nick says can be taken as an objective view or judgement. His actions throughout the novel, including his contempt towards Tom Buchanan and Daisy following their response to Gatsbys death, and his noble attempts to gather supposed friends and relatives to Gatsbys funeral, when they flocked to his parties, also add to Nicks honest nature and therefore Fitzgeralds presentation through him. Both Bronte and Fitzgerald share in the creation of their narrators as forming them as strangers discovering new and unfamiliar places; taking the reader with them as their knowledge and relationships develop. Both authors use the narrator in their novels for a variety of similar reasons. A narrator gives an added element of realism to the story, as if someone is actually telling something that happened. The use of precise dates and setting also add to this feeling of the novels being real. West Egg in Gatsby and 1801- in Wuthering Heights elucidating this point. The narrator also allows a detached character development that one is unable to achieve if the novels were written in the first person. Opinions can be posited and actions can be viewed externally to the actual character, making judgements more objective.

Assignment4 Assignment Example | Topics and Well Written Essays - 1750 words

Assignment4 - Assignment Example Saxophones are a common instrument in the contemporary society. Thus, the instrument can be found in musical classes or other Jazz sessions. The shiny nature of the instrument portrays it as an artistic masterpiece that arouses varied feelings on musical players. The instrument was originally intended for military and classical musical purposes. Owing to the versatility of the instrument, musicians in other genres around the globe are now playing the saxophone. Consequently, musicians in the avant-garde, classical, jazz, and pop and rock are playing the saxophone. The instrument can sound wild and poignant or smooth and stifling (Stewart et al., 5). The instrument can seamlessly blend into any joint, be it jazz big bands or orchestras. Moreover, the saxophone blends into the ensemble rock band solos or jazz quartets. Musicians in the contemporary world are trying to stretch the instruments into accommodating virtually every genre of music. Thus, the saxophone is steadily finding novel purpose in many genres of music. The design features of the saxophone depict an exceptional work of art. The design features appear attractive from the outward look to the inner features that create sound. The saxophone is a wind instrument of the nature of a conical bore. The instrument has a varying that increases from one end to the other (Hippe, 40). Thus, the instrument begins with a single diameter in one end that expands proportionately to the lowermost end of the instrument. By contrast, cylindrical instruments such as the clarinet, maintain uniform diameters in the whole length of the instrument. The varied design features of the saxophone have inner functionalities besides the outward looks. Conical bore instruments characteristically produce mellower and warmer qualities of tone compared to cylindrical instruments. Although saxophones are typically constructed using brass, plastic, gold and silver can also be utilized in the construction (Hippe,

Business Management Assignment Example | Topics and Well Written Essays - 2250 words

Business Management - Assignment Example An internal customer could be anyone within the organization. For e.g. Jessica and her team is an internal customer for the accounts department of that company because Jessica's team can not serve the suppliers and customers well until they have proper information from accounts and they are dependent on accounts. The suppliers were unhappy because they were given incorrect information at one instance and they rejected the products because some inputs were not of quality. This caused embarrassment and could have been prevented by close internal coordination. Another way of coaching employees, so that they can effectively fulfill customer needs, is to hire external consultant or auditor who periodically monitors their performance and can guide and train them. The customer service department at medical company was not in close communication with top management and their complaints and advice were not given due importance. Thus it will result in low motivation, poor customer service and people may tend to leave as their suggestions were not considered important in the organization. I have selected State library as the service provider organization as I have been interacting with this library for quite some time. The library provides a great environment to study with latest books on all subjects; magazines, periodicals, newspaper plus internet facility. The library is famous because it has taken in to accounts the needs and wants of their target customers who are between age 18 to 50. They conduct surveys to know about the preferences of the subjects of various age groups and keep the books according to it. The customer service policy of the library is attached at the end in appendix. ENSURING QUALITY CUSTOMER SERVICE The library through feedback process keeps themselves aware of the changing needs of the customer. Their staff go for unofficial visits to other libraries to observe what other best services are being offered there. This helps to improve themselves. Moreover they also take help of the best librarians of the country who guide them as to how they can improve their services. RESPONDING TO FEEDBACK The feedback from the customer is taken through the feedback forms placed at the entrance. Moreover a monthly feedback is taken from the permanent members of the library. Most of the customer's requests are regarding a new book or magazine to be kept in the library. They try to arrange that book and then personally inform the customer about the status of his request.

Different types of camps that the Nazi used and their purposes Essay

Different types of camps that the Nazi used and their purposes - Essay Example Thus, the Nazi’s established concentration camps in 1933 for terrorizing the Jewish communities1. During the period of 1933 and 1945, nearly 20,000 camps were built for the purpose of serving various functions. In order to effectively identify them, different names were given, such as labor camps or Arbeitslager, prison-of-war camps or Kriegsgefangenlager, transit camps or Durchgangslager, concentration camps or Konzentrationslager along with killing and death camps often referred as extermination or Vernichutungslager2. Initially the camps were built to hold political prisoners but following the World War II, the concentration camps were expanded and transformed with the intention to capture nonpolitical prisoners who were exploited by the Nazi’s through forced labor. The prisoners were literally ill treated and left to die because of the terrible living conditions. The use of concentration camps can be distinctly divided into three different periods, namely, 1933-1936 , 1936-1942 and 1942-1945. The first period saw the emergence of Adolf Hitler when the camps were primarily used for detaining political adversaries who opposed the Nazi government. Within a span of few months approximately 27,000 people were detained citing the reason of ‘protective custody’. The second period marked the emergence of World War II and the Nazi’s used these camps for forced labor. Throughout the entire period the inmates were treated as labors and were forcefully made to work for the Nazi’s. The last period i.e. during the late period of 1941 these camps were transformed into death camps where innumerable people belonging to the Soviet Union were tortured and murdered brutally3. Different Types and Purposes of the Camps Forced Labor Camps In September 1939, German’s invaded Poland following which numerous prisoners of war were confined and detained in these camps. The extreme living conditions forced these prisoners to die out of exh austion, starvation and torturous treatment. The prisoners were provided with improper facilities and during the winters they were compelled to stay without any clothes, proper nourishment and food. In these tough conditions the prisoners were forcefully required to perform various labor related works for the government agencies. The sophisticated males of Jewish were forced to live in ‘Ghetos’ and work in the plants that manufactured weapons used in wars. The Jews had no other choice than to work as it was the only possible way to survive in the shackles of the Nazi’s. The physically unfit Jews who were unable to work were shot and killed. In addition, the Nazis introduced a policy named ‘annihilation’ in which few types of prisoners were made to work, till death. They were purposely assigned works, the circumstances of which were bound to make them sick and die due to illness. For instance, at the Mauthausen concentration camp, the prisoners were a sked to carry boulders and run 186 steps which were made up of stone extracts every day until they fell sick and died4. In the year 1941, the Germans invaded Soviet Union and captured millions of people generally termed as Prisoners of War (POWs). These POWs were intentionally left to die by denying them the basic

Algorithm to Prevent Obstacle Collision

Algorithm to Prevent Obstacle Collision Description: In this paper, we develop an algorithm to prevent collision with obstacles autonomous mobile robot based on visual observation of obstacles. The input to the algorithm is fed a sequence of images recorded by a camera on the robot B21R in motion. The information is then extracted from the optical flow image sequence to be used in the navigation algorithm. Optical flow provides important information about the state of the environment around the robot, such as the disposition of the obstacles, the place of the robot, the time to collision and depth. The strategy is to estimate the number of points of the obstacles on the left and right side of the frame, this method allows the robot to move without colliding with obstacles. The reliability of the algorithm is confirmed by some examples. Keywords: optical flow, the strategy of balance, focus of expansion, the time for communication, avoiding obstacles. 1. Introduction The term is used for visual navigation of robot motion control based on analysis of data collected by visual sensors. Golf visual navigation is of particular importance is mainly due to the vast amount of recorded video sensor materials. The aim of our work is to develop algorithms that will be used for the visual navigation of autonomous mobile robot. The input consists of a sequence of images that are constantly available navigation system while driving the robot. This sequence of images is provided by monocular vision system. Then, the robot tries to understand their environment to extract data from a sequence of image data, in this case, optical, and then uses this information as a guide for the movement. The strategy adopted to avoid collisions with obstacles during movement a balance between the right and left optical flow vectors. The test mobile robot models RWI-B21R. The robot is equipped with WATEC LCL-902 camera (see. Fig. 1). Visuals caught using Matrox Imaging cards at a rate of 30 frames per second. Fig. 1 The robot and the camera. Fig. 2 shows a flowchart of navigation. Fig. 2 Algorithm for prevention of obstacles. The first optical flow vectors are computed from image sequences. To make a decision about the orientation of the robot, the calculation of the position of the image plane in the DMZ is necessary because the control is transferred to the law with respect to the focus of expansion. Then, the depth map calculates the distance to an obstacle, to provide an immediate response to a short distance from the obstacle, or to give a signal to the robot to ignore obstacles. 2. Otsenka movement Movement in the sequence of images obtained by camera induced movement of objects in 3-D scene and / or camera motion. 3-D objects and the camera motion is a 2-D motion image plane via the projection system. It is a 2-D movements, also called apparent motion or optical flow, and should be the starting point of the intensity and color information of the video. Most of the existing methods of valuation movements are divided into four categories: basic techniques of correlation, the basic methods of energy, basic methods of parametric model and the basic methods of differentiation. We chose the technique of differentiation, based on the intensity of the preservation of a moving point for the calculation of the optical flow, for this purpose, the standard method of Horn and Schunck (Horn and Schunck manual, B., 1981). After calculating the optical flow, we use it for navigation solutions, such as trying to balance the number of left and right sides of the flow to avoid obstacles. 3. The laws of optical flow and management As well as the observation point moves through the environment, and the sample beam, reflecting this point varies continuously generates an optical flow. . One way in which the robot may use this information to a movement to achieve a certain type of flow. For example, to maintain the orientation of the environment, the type of optical flow does not flow at all requests. If some flow is detected, the robot should change their strength by producing their effectors (whether wings, wheels or legs). so as to minimize this flow, in accordance with the control law (Andrea, PD; William H. Lelise PK, 1998) .. Thus, the change of the internal forces of the robot (as against external forces such as wind) is a function of changes in the optical flow (here from a lack of flow to the minimum flow) .. The optical flow contains information about the location of the surface and the direction of the observation point called the focus of expansion (CLE), the time to contact (TTC), and depth. 3.1. The focus of expansion (RF) For the translational movement of the camera, the motion picture is always directed away from the only point of the corresponding projection of the vector transmission to the image plane. This point is called Focus Expansion (DF), it is calculated on the basis of the principle that the flux vectors are oriented in certain directions with respect to the focus of expansion. At full optical flow is the horizontal part of the DF horizontally located, in accordance with the situation in which the majority of the horizontal components of variance (Negahdaripour, S. Horn, CP 1989). It can be estimated using a simple counting method, which counts the horizontal components of the signs, which focus on each point of the image. At the point where the maximum divergence, the difference between the number of RF components on the left of the right and the number of components must be minimized. Similarly, we can appreciate the vertical position of the FF by identifying the positions of most of the vertical components. Fig. 3 Calculation of the DF. Fig. 4 shows the result of calculating the risk factors in indoor RF is shown as a red square in the image. Fig. 4 The result of the calculation of risk factors. We also use optical flow to estimate the remaining time of contact with the surface. 3.2. Contact time The contact time (VC) can be calculated from the optical flow, which is extracted from monocular image sequences acquired during the movement. Speed Image can be described as a function of the camera parameters and is divided into two periods depending on the rotation (Vt) and the translational components (Vr) at the camera speed (V), respectively. The rotational part of the flow field can be calculated from the proprioceptive data (for example, the rotation of the camera) and the focal length. After global variable optical flow is calculated, (Vt) is determined by subtracting (Vr) from (V). From translational optical flow contact time may be calculated by the formula (Tresilian, J., 1990): Here? is the distance from the point in question (xi yi) on the image plane, the focus of expansion (FR). Note how the flow rate indicating the length of vector lines increases as the distance from the focus of the image expansion. In fact, this distance is divided at a constant speed, and is a relative rate used to estimate the time of contact. In Fig. 5 we show the VC assessment transfer sequence. (A). The corresponding graph of VC (b) consistent with the theory. Fig. 5 Evaluation of the VC. 3.3. Calculating the depth (intensity) Using the optical flow field is calculated from two successive images, we can find information about the depth of each flow vector calculation by combining VC and speed of the robot while taking pictures. where X depth, V is the speed of the robot, and T VC (calculated for each optical flow vector). Fig. 6 Calculation of depth. Fig. 6 shows an image depth, which is calculated by the VC. The darkest point is near, while the brightest point is the farthest from the scene, so the brightest point is the navigation area of à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹the robot. 3.4. Balance strategy for obstacle avoidance The basic idea behind this strategy is offset (parallax) movement, the robot translates nearest objects rise to more rapid movement on the retina than more distant objects. He also takes advantage of the prospects that closer objects also occupy a larger field of view, rejecting the average with respect to the associative flow. The robot turns away from the stronger flow. This control law is formulated: Here the difference in the strength of the two sides of the body of the robot, and Is the sum of the magnitude of the optical flow in the visual field of the hemispheres on one side of the header robot. We have implemented a strategy to balance our mobile robot. As we have shown in Fig. 7, the left optical beam (699, 24) is greater than the right (372, 03), so the solution is to turn to the right to avoid obstacles. (A chair to the left of the robot). Fig. 7 The result of the strategy of balance. 4. Experiments The robot has been tested in our laboratory robotics, robot containing, office chairs, office furniture and computer equipment. In the next experiment, we test the ability of the robot to detect obstacles using only the strategy of balance. Fig. 8 Robot vision. Fig. 8 shows a view from a camera robot initial snapshot. Fig. 9 The first decision. Fig. 9 (a) shows the result of a strategy of balance in which robots have to turn right to avoid the nearest obstacle (the board), and Fig. 9 (b) shows the corresponding depth image, which is calculated from the vector of the optical flow. We see that the brightest point is localized to the right of the image, which determines the navigation area of à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹the robot. Fig. 10 shows a robot when it turns to the right. Fig. 10 Robot vision. Fig. 11 (a) shows the result of a balance strategy in which the robot must rotate to the left to avoid the walls, and Fig. 9 (b) shows the corresponding depth of the image in which the brightest point located on the left side of the image. Fig. 11 The second solution. Fig. 12 The robot is in motion. Figure 12 (a) pokazyvet picture robot in motion in our laboratory, and Figure 12 (b) shows the path that passes by the movement of the robot. We notice that the robot found two principal positions, in which it changes the orientation, position (1) fit into the image and the position of the board (2) corresponds to the wall. Fig. 13 Schedule contact time. Figure 13 shows a graph of left and right optical flow. At the beginning of the stream picture left more than the right, so the robot turns to the right, which corresponds to Figure 12 (d), then right flow increases until it is larger than the left, because the robot is approaching closer to the wall than to the board and we see an increase in the two columns (left and right flow) through the structure 13 in Figure 5, and then the robot turns left, to prevent the wall, it corresponds to position 2 in Fig. 12 (g). It can be seen that the robot successfully wandering around the lab, avoiding obstacles; however, we found that the lighting conditions critically important to detect obstacles, because the image produced by the camera is more noisy in low light and makes the optical flow estimation more wrong. 5. Conclusions The article describes how the optical flow which provides the ability of the robot to avoid obstacles, use control laws, called strategy of balance, whose main purpose is to detect the presence of objects close to the robot on the basis of information on the movement of image brightness. The main difficulty in the use of optic flow to navigate, is that it is unclear what is causing the change of gray values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹(motion vector or changing the lighting). Further improvement of the developed method is possible by connecting other sensors (sonar, infrared ), in cooperation with the sensor chamber. 6. Links Andrew, PD; William, H. Lelise, PK (1998).

Argument for Legalization of Marijuana Essay -- Argumentative Persuas

Marijuana has become one of the most controversial drugs in America. Ever since its cultivation began around 1611, marijuana has puzzled people with its effects. Many question marijuana?s classification as a schedule one drug. A schedule one drug is one that has a high potential for abuse and no medicinal value. Some argue that the war on drugs, in particular marijuana, has cost taxpayers billions and is wasting funds that could be used on more important tasks such as improving transportation or education. As drug arrests rise, so do the populations in state prisons. This has become an immediate problem with no real solution. The legalization of possessing small amounts of marijuana can contribute positively to the medical and economic world as well as cut down on the prison population. Many people today use marijuana for multiple reasons. There will always be the teenager who tries it for the first time and enjoys the ?high? that comes along with smoking it. Besides those who smoke it for recreational purposes, there are those who need the plant as a form of medication. People suffering from a wide range of diseases and sicknesses such as AIDS and Glaucoma have claimed that it has benefited them. Numerous medical associations in the U.S. and abroad have done many tests to find the benefits and harms of marijuana. These tests come up with the same conclusion that marijuana is just as much if not more helpful than harmful. Approximately 400, 000 Americans die every year from a smoking related illness. In 5000 years of recorded use, marijuana has never been linked to a single death, overdose, or acute toxicity (Schlosser 48). Many cancer patients have used marijuana to combat nausea and pain. AIDS patients hav... ...wo percent of drug cases so the influence could not be measured accurately. In 1997, only 15 percent of state and federal inmates received substance-abuse treatment during their current terms. That number is down from 1991. There will always be a group of people that find some concepts as preposterous. There were those who believed that watching a talking box would never be entertaining. There were those that laughed in the Wright brother?s face when they proposed the idea of a flying machine. The idea of legalizing marijuana may seem absurd to those who do not use it but for those whose life it will improve, it seems like a grand idea. There are products on the market that can compare to marijuana?s negative effects yet those products are legal. When will America wake up and realize the cry for the legalization of marijuana is growing louder than ever?
