Impact of Jet

C IMPACT OF JET EXPERIMENT 1 Aim To find the impact force caused by a fluid jet on a horizontal plate and a hemispherical shell and compare it with the expected theoretical force. 2 Theory When a rubber ball strikes a solid surface it nicely rebounds from the solid surface. The amount of rebound would depend on the coefficient of restitution. However, when a steady fluid jet strikes a solid surface, it does not rebound. But, a stream of fluid is formed which moves over the surface and the fluid leaves the surface tangentially. If a fluid jet is impacting a horizontal plate, at an angle ? the rate of change of momentum can be equated to the force exerted by the jet on the plate. When a vertical fluid jet strikes a horizontally positioned plate, the value of ? will be 90Â °. A control volume analysis can be performed to give the force F = ? QV, (1) where ? is the density of the water, Q is the jet flow rate and V is the velocity of the jet. For the case of a hemispherical shell when t he stream of water is turned back by 180o, the force experienced by the shell will be F = 2? QV, (2) two times the force experienced by the flat plate. Experimental Set-up The set up consists of a closed cylindrical container housing the horizontal plate/hemispherical shell to receive the impact of the jet. The vertical water jet is produced by a pump forcing water through a nozzle of diameter 6mm for the flat plate and of diameter 8mm for the hemispherical set up. The flow rate through the nozzle is measured by a rotameter. The velocity of jet could be obtained by knowing the flow rate. 4 Experimental Procedure Switch on the motor and using the two gate valves control the flow rate.Place suitable weights to counter balance the impact force of the liquid jet. When the load is higher than the impact load of the jet, the jet will be blocked by the plate. When the load is low the load arm will rise up and touch the top part of the housing. Adjust the flow rate for any selected weight s o that the load arm stays in the middle of the distance from the nozzle tip to the top part of the housing. Ensure that the steady flow rate is maintained and take at least six independent measurements by choosing six different flow rates that would balance the weights.Important steps 1 Allow the float to be steady before you start noting down the readings. 2 Ensure that the fluid jet nicely counter balances the weight it is carrying.

Gertrude’s as Shakespeare Essay

Where a twenty-first century audience would express sympathy for Hamlet’s loss and would understand his hesitation in taking vengeance, an Elizabethan audience would not sympathise towards him for avenging his father’s death, and would question why Hamlet is showing inaction. As Dori Ripley suggests, ‘The church advocated God’s vengeance, while the state demanded justice through God’s chosen representative(s)’ (Ripley, 1), meaning it would be Hamlet’s duty to avenge his father’s death in the eyes of the Elizabethan Church, for God’s cause. Therefore, this would certainly contribute to Hamlet’s turmoil, with the added pressure to ‘exact God’s vengeance on the wicked’ (Ripley, 2), and become King of Denmark. However, in the eighteenth century, Thomas Hanmer drew attention to Hamlet’s delay in avenging his father’s death, suggesting that ‘Had Hamlet gone naturally to work there would have been an end of our play’, meaning Shakespeare’s play would not have been as dramatic for his intended audience of his era. Ernest Jones suggests that Hamlet refrains from killing Claudius earlier in the play because he had already committed the deed Hamlet himself subconsciously wished to carry out; ‘The long â€Å"repressed† desire to take his father’s place in his mother’s affection is revealed in unconscious activity by the sight of someone usurping this place exactly as he himself had once longed to do’ (Jones, 99). This is evident in the play when Hamlet has the opportunity to kill Claudius, however he decides to wait for when he is in ‘th’incestuous pleasure of his bed’ so he is guaranteed to suffer the same pain Hamlet’s father did when he was in purgatory. Eliminating his competition in the most torturous way suggests Hamlet’s hatred towards Claudius for marrying his mother. As an extension of this Hamlet is somewhat hostile to his mother throughout the play, shown through the language Shakespeare uses when Hamlet is alone with her. His anger towards his mother’s sexuality is expressed, thus: O shame, where is thy blush? Rebellious hell, If thou canst mutine in a matron’s bones, To flaming youth let virtue be as wax (3. 4. 82-4) Hamlet demands to know how young people can be expected to control their passions if mothers cannot control theirs. In the same scene, Hamlet pleads with Gertrude not to sleep with Claudius that night and to, Refrain tonight, And that shall lend a kind of easiness To the next abstinence (3. 4. 166-8) After that until she no longer wishes to sleep with Claudius. Whether this is right must be considered in psychoanalytic terms because abstinence stores up emotions that leads to a later emotional explosion. In the context of the play as a whole, this is symbolic because throughout Hamlet stores up his confusion, anxiety and turmoil until he explodes in the final scene, ending in death and destruction of the dynasty. Recent developments in Hamlet criticism suggest Hamlet’s attitude towards his mother can be explained in terms of Freudian psychoanalysis, in particular the Oedipus Complex where ‘unconscious ideas and feelings centre round the wish to possess the parent of the opposite sex, and eliminate that of the same sex’ (Rycroft, 118), according to Charles Rycroft in ‘A Critical Dictionary of Psychoanalysis’. Although this is a modern theory which did not exist during the Shakespearean period, Shakespeare unconsciously reflects this possible interpretation of character in the play. Hamlet seeking to avenge his father by eliminating Claudius, his mother’s husband, could be one of his motivations and subsequent causes of his emotional turmoil. His confusion is, therefore, redirected onto Ophelia who experiences Hamlet’s anguish. Rycroft also suggests that this is symbolised in Hamlet as ‘persons who are fixated at the oedipal level that are mother-fixated or father-fixated reveal this by choosing sexual partners with obvious resemblances to their parents’ (Rycroft 119). However, Ophelia’s qualities are not representative of Gertrude’s as Shakespeare suggests Gertrude tends to sexually dominate men in the play whereas Ophelia is obedient to them, suggesting she is vulnerable. Therefore, whether Rycroft’s analysis is related to the play must be considered because it does not directly link to Hamlet’s situation, choosing to have a relationship with Ophelia because she resembles his mother he has sexual desires for. In Gertrude marrying Claudius, Hamlet’s jealousy is provoked, which eventually contributes to his rage when alone with his mother, ‘You are queen, your husband’s brother’s wife’. Here, Shakespeare shows Hamlet’s confusion within his complex situation, that his mother has become queen by incestuously marrying her husband’s brother. Combined with Hamlet’s oedipal fantasy and his mother’s new marriage, therefore, he is bound to show rage and confusion towards his mother and hostility towards her new partner. In conclusion, Hamlet is a character whose mind is in turmoil, which is subliminally presented through Shakespeare’s use of soliloquies. This turmoil could exist due to Hamlet’s life experiences, whether they were his father’s death or his mother’s hasty marriage to his uncle, who murdered his father. These occurrences may have caused Hamlet’s confusion between mothers and lovers, his contemplation of suicide and his hostility towards others, resulting in catastrophe at the end of the play. An Elizabethan audience would not sympathise with Hamlet’s hostility towards other and his delay in taking vengeance and so could argue that his mind is in turmoil, the reason why he is inactive.

Finance and Resource Management - Essay Example On the other hand new vehicle would be depreciated by $900 if the same technique were to be followed. The vehicle would be used, on an average 80 kilometers. The fuel efficiency is 8 kms per litre of petrol. Thus, there is a requirement to use 10 liters petrol. Each litre is costing about $2 and so petrol cost would be $20 per day and for 355 days, it would be $7100. The new vehicle has better fuel efficiency giving 10 kms per litre. It would thus require 8 litres per day and with the same cost of petrol, the yearly requirement would be $5680 (that is, 8 litre * $2 * 355 days). Cost of maintenance has gone up in the recent time. As the vehicle has been subject to severe wear and tear, the maintenance cost is estimated in the order of 20 percent of the car. That is, $1000 this year. But maintenance cost for the new car would be very low. It would not exceed 2 percent of its actual cost. This would be therefore $180 per year. Based on the information provided as above, the budget for operating the old vehicle has been mapped below. This has been juxtaposed against the possible cost that will be incurred for operating a new vehicle for similar purpose. Based on the above consideration, operating old vehicle is costlier than the new one. For instance, the annual cost of running the old patrol car is $8600, whereas that of new car would be $6760. There is a difference of $ 1840. In one of the company meeting, it was decided to have annual gathering under the pretext of a training program. The participants included middle level manager numbering about 25 from the United States. The department conducted basically a training program involving talk by about eight invited guests, who had to be given mementos. As these experts were drawn from best performers’ list working for our organization, it was decided that no honorarium would be paid. These participants were asked to stay in a hotel for 2 days. Hotel room tariff was $ 400 per day on twin sharing

No Child Left Behind Essay Example | Topics and Well Written Essays - 3000 words

No Child Left Behind - Essay Example Next is the improvement of flexibility and local control. It also provides an increased number of options for parents. Lastly it stresses on proven teaching techniques. The phrase, "No Child Left Behind" (NCLB) has become a slogan for the federal scheme to increase "accountability" in American education. But despite the fact that NCLB is a federal plan, it will be up to the individual countries to make the plans and procedures that accomplish NCLB requirements. NCLB does not provide the new mandate with adequate funds. Thus this has an effect on opinions of many schools and parents. Many states have implemented this policy by now, but this has an impact on the parents and schools as they had to face many difficulties while coping up with the policy. This article further describes the effect, changes and pros and cons of the policy in regard to its laws.(Edwards & Perry 2004) This act generally stresses on developing American schools to a standard in which all students are given equal opportunities. As in the act it states "close the achievement gap between high- and low-performing children, especially the achievement gaps between minority and non-minority students, and between disadvantaged children and their more advantaged peers." This clearly reflects that NCLB aims to offer reasonable and equivalent opportunities to the students so that they can attain education of high standards. One of the most important terms of NCLB is the obligation that the states should set values in the field of education and should perform yearly evaluation of schools to check the progress of the school and analyze if the schools have been successful in improving the student's educational achievements. NCLB gives funds for the training of teachers; it provides special support to students who face difficulties with reading and supports immigrants and homeless students. Overa ll NCLB holds the states, districts and the schools to take accountability of the student's achievements. States are entitled to report the progress of students who suffer from problems like reading and writing. They are also directed to report about the students who are from different ethnic groups and who belong to families of low income. On the contrary NCLB has passed laws which act as a barrier for admission in kindergarten. Thus this proves to be a setback for the youth in their future. This youth may suffer from problems like aging, race difference and other physical and mental differences. A child cannot get admission in a kindergarten or a primary school if he has not cleared certain eligibility criterion (Panzica 2008). The laws implemented in the United States of America are prohibiting the children from early entries into kindergarten and primary schools. This can immensely affect the future of the children as it may determine the age of the child when he finishes his high school. There is a certain age limit for any child who needs admission in the kindergarten. If one is not able to comply with the age limits then they possibly will not get an admission into the school. The Act has made the school authorities more accountable for the results of the students and this has therefore made the authorities more conscious when giving admission to a child of less capabilities. The age criterion is so strict that the schools have a certain date setup (usually in September or December) at which the child should be of the

F. R. Leaviss Description of Hard Times as a Moral Fable Essay

F. R. Leaviss Description of Hard Times as a Moral Fable - Essay Example To delve deep into the contention of this great man regarding one of the all time masterpieces in English literature, â€Å"Hard Times† by Charles Dickens and to examine the contention of Leavis regarding â€Å"Hard Times† as a moral fable, it become mandatory at the outset, to analyse and explore the subtle aspects operating through the novel’s scheme of things and the background and social conditions in which it was produced. Since the publication of the novel, it has been widely received and criticised by different critics across the globe and from different age. Apart from Leavis, George Bernard Shaw and Thomas Macaulay had criticised the novel on the aspect of Dickens’ delineation of the Utilitarian, trade unions and post-Industrial Revolution which neatly divided the capitalist mill owners and worker class in the British society during Victorian Era. Hard Times as A Moral Fable: Through the Eyes of Leavis ‘Hard Times - For These Times’ o r popularly known by the name of only Hard Times is the tenth novel authored by Charles Dickens and was published in the year 1854. To understand the contention of F.R. Leavis in coining the novel as a moral fable, it becomes essentially important to understand the literary term ‘moral fable’ in the first place. Moral fable is a kind of a story that involves the imagination and logic and combines them at the same platform.

RAS AL KHAIMAH MEDICAL DISTRECT Essay Example | Topics and Well Written Essays - 1500 words

RAS AL KHAIMAH MEDICAL DISTRECT - Essay Example The employee’s salaries are very low and hence they have incentive to make any organizational commitment. In addition to this, the MOH Has not made any efforts to improve their policies and procedures when their employees are concerned neither do they monitor their performance. Hence the MOH faces so many problems that result in poor job satisfaction and poor turnover and in this research we intend to make use of theories to understand these problems in a better light and find some solutions to them. 1. Problems faced in the ministry This project focuses on the Ministry of Health in Ras Al Khemiah. Presently, the ministry is facing many problems of which organizational problems are a major part. Some of the problems faced by the Human resources department are that of Organizational behaviour and the implementation of procedures to improve motivation and satisfaction among its employees. Poor organization culture, leadership behaviour between staff and the employers and decreas e in the company turnover due to employee problems. This research is about to understand and analyze the different variables, individual motivation and its causes, the deficiency of the application of human resources, job satisfaction among the employees, organization culture and poor choice of good leadership, poor motivation due to poor job satisfaction. In such a scenario it becomes very important to understand the causes leading to such issues so that we can rectify them for better outcomes. Some of the primary causes responsible for poor organizational culture and behaviour are a lack of trust between the employers, managers and the employees, lack of focus and good motivation, poor leadership skills, focus is more on the individual goal than the company goal, intolerance and poor communication between employers, staff and employees. 2. Description of the Company and its choice The Ministry of Health (MOH) is the organization chosen for this research for the following reasons . The Ministry of Health is facing a lot of organizational problems which is the main focus of this study. This research will help students to better understand the behaviour problems that various companies face in the real business world. The Ministry of Health clearly portrays the importance and relationship of each variable such as good leadership qualities and the impact it has on the success or failure of an organization. Group Level, Leadership In the group level analysis, our focus would be on Leadership and how it impacts upon the workplace. According to (Robbins & Judge 2009, p410) Leadership is defined as the ability to impact upon a group working towards the achievement of a specific goal or vision. In (Robins & Judge, 2009) opinion, neither are all leaders managers, nor all managers leaders. Leadership also has the capacity to bring about motivation by influencing the individual towards the success of the organization. This definition of leadership implies that leadership is â€Å"â€Å"the ability of an individual to inspire, motivate, and enable others to contribute to the effectiveness and success of the organization† (House et al 1999, p184) Good leadership is therefore crucial to the success of an organization through increased productivity. Yuki (2010) defines leadership from various perspectives such as Trait Theories, Behavioural Theories, Contingency

Empowering People through Education Essay Example | Topics and Well Written Essays - 750 words

Empowering People through Education - Essay Example Universal education has been on the global agenda since the 1948 Declaration of Human Rights proclaimed free and compulsory education to be a basic human right. The 1990 Convention on the Rights of the Child, signed by all but two of the world's governments, reaffirmed this right as a legally binding obligation. Since then, there have been many high-level international commitments to education for all (Bloom & Cohen, 2002). Indeed, education is a tool for human beings to push them to advance their goals in life. This is the reason why education was inculcated in the Declaration of Human Rights. This is also why, of all American institutions, the educational system has perhaps the greatest impact on the lives of ordinary people. Children gain knowledge about a standard range of subjects from English and history to mathematics and science. They also learn social skills and are exposed to different people and ideas. Educational achievement is the single largest influence on an individual's future earning power. More than anything else, in fact, it is education that shapes a person's future. Professor Stephen Heyneman of Vanderbilt University, in his article "Are We Our Brothers' Keeper", pointed out that that economic development depends on educational progress. The evidence supporting this claim emerged from multiple sources and common intuitive judgment: nations with an educated population are economically adaptable, healthy, and innovative. But the challenges to providing education in low-income countries are daunting. Generally, they can be divided into three categories: schooling's access, quality, and purpose. This is why world leaders are thinking how greater educational opportunity can be provided to low-income countries, how the quality of that opportunity can be improved, and how the international community should guide these schools to reduce extremist nationalist and religious curricula (The World and I, 2003, p. 18). So if "ignorance is bliss", why do we still pursue to educate ourselves and our children It may be true, but no individual wants to become ignorant. If a person is not educated, he or she is susceptible to being taken advantage of. Holmes (1981) offered a more viable answer to this question by expounding the aims of education. According to Holmes (1981), these aims are often expressed in general terms in order to induce widespread public appeal. Aims such as the holistic development of children and the acquisition of skills and knowledge deemed desirable for societal well-being are often palatable to a variety of stakeholders, including governments, businesses, parents, educators, and students (Holmes, 1981). Thus, the intentions of education, as Holmes has argued, are often described in terms of their intrinsic value (knowledge for knowledge's sake), their social value (process of initiation into acceptable social standards), and their intended outcomes (all-around individual devel opment). The aims of education, therefore, represent a society's idealized hopes and visions for its citizens: In so far as aims are statements of what "ought to be the case" and represent man's hopes and aspirations not only for himself but for future generations, they are part of our socially constructed world and can be accepted or rejected according to taste. (p. 114) Thus, the aims of educa

The Liberty Leading the People - Eugne Delacroix Essay

The Liberty Leading the People - Eugne Delacroix - Essay Example The painting reveals the picture of a heroine carrying a flag and a musket slightly at the right of the painting. There is also a child who is holding two guns on the right of the painting. Additionally, another man is holding a sword and is armed for battle on the left corner. There is also another young man holding a musket at left of the painting. Apparently, many people are helplessly lying on the ground. In the background a blue sky and light is seen on the horizon. The flag carried by one woman, the heroine, is colored red, white and blue. The men, who are armed, are dressed in uniform ( Coetzee 45). The uniform constitutes of grey shirts, black three-piece tops, and khaki trousers. Additionally, all the armed men are wearing hats. The men are also carrying black bags with a certain trademark and a white handle. The buildings near the scene of the battlefront seem demolished. Some of the people lying down are in the same uniform as that of the men in action. The parts of the ar t, which are in light are the standing people like Eugene Delacroix and the woman with a rifle. The subdued people are in shade and the source of light is the rising sun at the horizon. The painting has a good mixture of colors, which have been used to create dà ©cor and beauty of the images and the background. The whole scene reveals a fierce confrontation between two rival groups and the scene that catches my eyes is the woman carrying the flag implies that a battle was worn and the group owning the flag worn the battle (Delacroix sand ONeill 67). The figures are intriguing and attractive to the audience especially because of the colors used to present them. There is movement portrayed by the painter. The woman with a rifle is presumed to be in motion given her position. The three dimensional reflection of the painting is manifest in the creative location of the background, the sky and the people at the forefront. The painter was standing at the front

Admissions Essay Essay Example for Free

Admissions Essay Essay Even since high school, I feel that I may have grown used to thinking that I will become a successful nurse someday. I envision myself, being like my two elder sisters who are nurses, being one of the best in this line of work. However, I do not regard this profession as a mere line of work. It is not a mere responsibility foster and nurture people, even unfamiliar ones. I honestly believe that there is a thin line between harboring life, and putting it in disrepair. I acquired my zeal for nursing since I was still in early high school. My two elder sisters, as mentioned, are also nurses. Sometimes being able to see them work, most of the time seeing them looking after patients’ health, as if it was their own, observing them obtain the satisfaction from helping other people†¦these are just some of the reasons that make me admire the people in that field of work. Moreover, my life experiences thrust me to practice Nursing and really put my life into it someday. My younger brother, who is indeed very dear to me, almost died when he was 8 months old. As what I was capable of understanding at that time, his temperature reached 107. See more: Satirical elements in the adventure of Huckleberry Finn essay 5 degrees, triggered by an ear and throat infection, which almost took his life. Throughout his illness, he was not able to do a lot of daily activities without someone to assist him. So, as his sister, I was there to look after him. I was there to nurse him, to assist in his needs, and make sure he was doing fine, at least that was what I can do. It is not that I am singing my own praises. It is just that, somehow, I feel that without someone to help or assist a sick person, he may not have been able to overcome such an illness. I am pleased and fulfilled to say I have taken care of my brother and helped him get through his ailment. I may have served as a support system for him, as well as my own family, in making things better, making him better, and keeping that thin line between life and death from becoming thinner for my dear brother. Sometimes when I look back to this experience, I tend to tell myself how possible I would have lost to death someone who is very close to me. I knew I did something for him, for him to get better. And somehow, that made me feel fulfilled. Thus, that gave me the inspiration to really push through a career in the future, such as Nursing. Inspired by my two elder sisters, enthused by my younger brother, I said to myself, I want to become a Nurse someday. Pursuing this field of interest is not just for and as my college course, but as a lifetime craft and vocation. It is not a mere money-earning job for me. Rather, as what I see from my siblings, I picture it as a self-fulfilling, people-caring job. I have lived my whole life in the small town of ____________. And in this small town, within the twenty years of my life, I have also been exposed to doing community work. I do volunteer works once a month at the nursery in my church at ______________. There, I teach three and four-year old children. Throughout doing this, I developed in myself the love for little children. That is why, when I become a nurse someday, I would really want to experience working specifically in relation to Pediatrics. Taking care of babies and innocent children feels like serving the satisfaction of being well appreciated. As far as what I have experienced, when children are well taken care of by adults, they give them high regards for making them feel well, especially when they are sick. Still, even if other soon-to-be nurses think that pursuing this career is a fast way to earn money by either staying in this country or going abroad, I still would prefer working at my little town where I grew up. When I finish my college degree as a Nurse, I would want to start working where I developed by passion for taking care of other people. It is because ___(Name of town)__ is where I will owe my success, hopefully. Besides, I also believe it is always a good deed to start helping your family and neighbors first, before you get on with the big world. At least, it would be a very good and fulfilling experience if I would be able to help my small town, in my small ways, at the start of my career. Since I am going to college soon, hopefully being able to pursue Nursing in ____Name of University___, I would be able to fully enhance and invigorate my passion for taking care of other people, and particularly their health. Because of my life experiences, especially with regards to my brother, I realized how important life is. And people need people who will take care of them when they are sick, people who scientifically know about health and who emotionally values life. And I believe I possess the qualities that it takes to become one good and successful nurse. One day, I told myself, I will be like my sisters. Dressed in clean white uniforms, taking care of my kin. As far as I know, nurses are indeed in demand here in the United States and in other continents like Europe. But I would prefer to stay here and serve my family and the rural town where I grew up. By the time I graduate, the need for nurses may have probably risen and I will be there to practice my profession, nurture and take care of people and live up to the care I have done for my brother and the inspiration I got from my sisters. And pursuing this as my college degree would be a step closer to my dream.

Antilock Brake System Abs Model Based Design Computer Science Essay

Antilock Brake System Abs Model Based Design Computer Science Essay An Antilock Brake System (ABS) is a closed loop control system that modulates the brake torque that is applied to the wheel in order to prevent the controlled wheel from becoming fully locked. ABS is among the most important safety systems in a vehicle. In automatic highway system, automatic brake actuation is a very important part of the overall vehicle control system. It prevents the wheel lock-up under critical braking conditions, such as those encountered with wet or slippery road surfaces and driver panic reaction (Bosch, 1995). By preventing the wheel lock-up, ABS ensures that the vehicle remains responsive to steering wheel inputs. Reduced stopping distance on account of ABS is more evident on wet or slippery road surfaces (Garrick et al., 1998). 1.2 MODEL BASED DESIGN Designers of embedded control system software face difficult challenges. In addition to the need to complete projects at low cost and within tight schedules, embedded control system software designers must provide predictable performance and competitive features for the products they deliver. Traditional methods of designing, testing, and implementing embedded control systems cause designers to wait until late in the design effort, when actual or prototype products and real-time embedded targets become available, to find out if software really works as it was intended to. Only then, as system integration occurs, can the designer uncover the errors that may have found their way into the product during the early design stages. Model-Based Design with MathWorks tools provides a proven technique for creating embedded control systems. It is used today for satellites, aircraft, and many other aerospace applications, in the automotive industry, and for process control, computer peripherals and industrial machinery. Through Model-Based Design, embedded control system design teams can begin evaluating software designs without using prototype products and real-time targets. The MathWorks environment for Model-Based Design allows engineers to mathematically model the behavior of the physical system, design the software and model its behavior, and then simulate the entire system model to accurately predict and optimize performance. The system model becomes a specification from which you can automatically generate real-time software for testing, prototyping, and embedded implementation, thus avoiding manual effort and reducing the potential for errors. Fig 1.1. Model-Based Design for embedded control system software Changes or corrections to the system requirements and specifications are easily incorporated into the model, fully evaluated by simulation, and automatically reflected in the final real-time embedded software. 1.3. MODELING AND SIMULATION To effectively design an embedded control system and accurately predict its performance, designers must understand the behavior of the entire system in which the control system will reside. MATLAB and Simulink form the core environment for Model-Based Design for creating accurate, mathematical models of physical system behavior. The graphical, block-diagram paradigm of the MathWorks environment lets you drag-and-drop predefined modeling elements, connect them together, and create models of dynamic systems. These dynamic systems can be continuous-time, multi-rate discrete-time, or virtually any combination of the three. You can create custom model elements or reuse legacy code-based models by incorporating C, Fortran, or Ada code directly into the modeling environment. The modeling environment is hierarchical and self-documenting. System structure and function can be clearly expressed by grouping model elements in virtually any combination, allowing large teams to work concurrently on the design. Libraries of hierarchical elements can be quickly created, allowing those elements to be reused easily by other members of the design team or on subsequent designs. Fully integrated into the environment is the capability to graphically model event-driven systems using state charts, truth tables, and flow diagrams. Specialized capability for mechanical and electrical power systems allows models of these systems to be constructed using modeling elements that correspond directly to the structure of the physical system, avoiding the need to express them as mathematical equations. If prototype or actual physical systems are available and input/output data can be acquired from them, mathematical models can also be created using system identification techniques. As soon as a hierarchical element of the model is constructed, that element can be simulated. Simulation allows specification, requirements, and modeling errors to be found immediately, rather than waiting until later in the design effort. As the model becomes larger, through the addition of hierarchical elements or by increasing the complexity of existing ones, the designer can continue to find and correct errors during simulation by using the model coverage, performance profiling, and interactive debugging features. When the physical system model is specified to the required level of detail and simulation has shown the model to be accurate, the control system can be designed. 1.4. CONTROL SYSTEM SOFTWARE DESIGN With the behavioral model of the physical system available, the designer can begin the embedded control system software design. The MathWorks environment for Model-Based Design supports many types of control system design techniques and requirements that range from the simple to the most complex and large-scale. For example, some product designs may require using linear control design methods to determine the correct algorithms and parameters for the control system software. Using MATLAB and Simulink, the designer can automatically create the linear physical system models needed by this design technique, calculate the parameters, and then visualize the results using Bode plots and root locus diagrams. Other applications may require less sophisticated techniques to determine the correct control system design. Regardless of the control system design method used, the MathWorks environment for Model-Based Design helps the designer use interactive simulation to quickly evaluate each contr ol system design model in conjunction with the physical system model and avoid the risk, expense, or need for prototypes or actual physical systems. As the control system functional design is completed and the target environment needs to be considered, the designer can specify implementation details for the software directly in the modeling environment. The MathWorks environment supports all aspects of control system software design, including processor, interface, or standards issues. For example, you may need scaled integer or fixed-point data types for target processors that have no floating-point math capability. The effects of fixed-point mathematics can be evaluated by simulation, to see if the proper data sizes and scale factors have been selected. Data structures that are needed to meet software standards or target environment interface requirements can be defined as part of the system model and then realized when the embedded control system software is automatically generated. When the control system software design is complete, you can simulate the entire system model. During simulation, you can automatically collect model profiling and coverage information that will help you assess performance and discover errors. If performance does not meet expectations or errors are found, you can easily change the model to correct the problem and then simulate the model again to confirm the change or correction. Once simulation of the entire system model has shown that the design meets the desired performance requirements, you can automatically generate software for real-time testing and implementation, using the model as a specification. 1.5. EMBEDDED SOFTWARE TESTING AND IMPLEMENTATION Using the system model and Real-Time Workshop, real-time code for testing, validation, and embedded implementation on the production target processor can be automatically generated. As it is created, the code is automatically optimized for fast execution and efficient use of memory. Automatically generating code from the system model avoids errors due to manual translation of the model into code, and saves time, allowing software developers to focus on more demanding tasks. The MathWorks provides a turnkey software environment called xPC Target for real-time prototype testing, calibration, and validation of this automatically generated code using a PC-based hardware target system. xPC Target includes a real-time kernel, device drivers, and all the support software needed to create a rapid control prototyping system for real-time software testing and validation. It can also be used to provide hardware-in-the-loop capability, using code generated automatically from the physical system model. Hardware-in-the-loop testing allows the designer to simulate the real-time behavior and characteristics of their physical system, so that prototype or production control system software can be tested without the need for the actual hardware or operational environment. For embedded system designers who prefer an integrated capability, The MathWorks has a fully tested, custom configured, PC-based target hardware system. Chapter 2 MODELING AND SIMULATION 2.1. MODELING A computer model, as used in modeling and simulation science, is a mathematical representation of something-a person, a building, a vehicle, a tree-any object. A model also can be a representation of a process-a weather pattern, traffic flow, air flowing over a wing. Models are created from a mass of data, equations and computations that mimic the actions of things represented. Models usually include a graphical display that translates all this number crunching into an animation that you can see on a computer screen or by means of some other visual device.   Models can be simple images of things-the outer shell, so to speak-or they can be complex, carrying all the characteristics of the object or process they represent. A complex model will simulate the actions and reactions of the real thing. To make these models behave the way they would in real life, accurate, real-time simulations require fast computers with lots of number crunching power. 2.2. SIMULATION Simulations (and models, too) are abstractions of reality. Often they deliberately emphasize one part of reality at the expense of other parts. Where as models are mathematical, logical, or some other structured representation of reality, simulations are the specific application of models to arrive at some outcome. 2.2.1 Types of simulations Simulations generally come in three styles: live, virtual and constructive. A simulation also may be a combination of two or more styles. Live simulations typically involve humans and/or equipment and activity in a setting where they would operate for real. Think war games with soldiers out in the field or manning command posts. Time is continuous, as in the real world. Another example of live simulation is testing a car battery using an electrical tester. Virtual simulations typically involve humans and/or equipment in a computer-controlled setting. Time is in discrete steps, allowing users to concentrate on the important stuff, so to speak. A flight simulator falls into this category. Constructive simulations typically do not involve humans or equipment as participants. Rather than by time, they are driven more by the proper sequencing of events. A simulator is a device that may use any combination of sound, sight, motion and smell to make you feel that you are experiencing an actual situation. Some video games are good examples of low-end simulators. Simulations are complex, computer-driven re-creations of the real thing. When used for training, they must recreate reality accurately; otherwise you may not learn the right way to do a task. 2.3. MODELING AND SIMULATING ORDINARY SECOND ORDER DIFFERENTIAL EQUATION Consider the second order differential equation (1) This can be written as two first order differential equations if we introduce two new variables, x1(t) and x2(t).   Let x1(t)=y(t).   We can then write two coupled first order equations. (2) (3) The solution can be approximated in Simulink by using two integrators to integrate the first order derivatives. 2.3.1. Building a Simulink Model We start Simulink from the Matlab prompt by typing Simulink.    We will be needing blocks from the Source, Sink, Linear and Non-linear libraries, so double click on them to open them up.   In the window labeled untitled, drag two integrators from the Linear library, connect them, and change their labels. Fig2.1. Building Simulink Model (Step 1) The input to the leftmost integrator is the derivative of x2, and its output is x2.   The input to the rightmost integrator is the derivative of x1 (=x2), and its output is x1.   We can complete the representation of the differential equation except for the input, by adding two gain blocks (and flipping them using the Format option of the Simulink menu. Fig2.2 Building Simulink Model (Step 2) To add the input we will use the clock (from Source), the trigonometric function (from Non-Linear) and another gain block.   The completed diagram should look like the one shown below. Fig2.3. Building Simulink Model (Step 3) 2.3.2. Running Simulation and Viewing Results To view the results of the simulation, add a scope (from Sink).   In this case we only want to view 80 ms of simulation, so go to the Simulation menu and choose Parameters, and set the stop time to 0.08 seconds.   To start the simulation hit the start button, or go to Simulation->Start.   The scope output is shown below (after zooming with the Binocular tool at the top of the scope window. Fig2.4 Simulation Results of the Model It is often desirable to save the data to Matlab.   To save the time variable, the input and the output, we add three To Workspace blocks (from Sink) and give them each a different name (these are the names of the variables that will be in the Matlab workspace). Fig2.5 Building Simulink Model (Step 4) Chapter 3 ANTI-LOCK BRAKING SYSTEM 3.1 INTRODUCTION Antilock Braking Systems (ABS) are closed loop control devices within the braking systems which prevent the wheel lock-up during braking and as a result, retain vehicle steerability and stability. The main ABS components are hydraulic modulators, wheel speed sensors, ECU for signal processing and control and triggering of the signal lamp and of the actuators in the hydraulic modulator. Fig 3.1 Location of the ABS in a vehicle 3.2 DESCRIPTION OF THE SYSTEM The theory behind anti-lock brakes is simple. A skidding wheel (where the tire contact patch is sliding relative to the road) has less traction than a non-skidding wheel. If we have been stuck on ice, for example, we know that if the wheels are spinning we have no traction. This is because the contact patch is sliding relative to the ice. By keeping the wheels from skidding while we slow down, anti-lock brakes benefit in two ways: The vehicle stops faster, and we will be able to steer while we stop. There are four main components to an ABS system: Speed Sensors, Pump, Valve and an ECU. 3.2.1 Speed Sensor The anti-lock braking system needs some way of knowing when a wheel is about to lock up. The speed sensors, which are located at each wheel, or in some cases in the differential, provide this information. 3.2.2 Valves There is a valve in the brake line of each brake controlled by the ABS. On some systems, the valve has three positions: In position one, the valve is open; pressure from the master cylinder is passed right through to the brake. In position two, the valve blocks the line, isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. In position three, the valve releases some of the pressure from the brake. 3.2.3 Pump Since the valve is able to release pressure from the brakes, there has to be some way to put that pressure back. That is what the pump does; when a valve reduces the pressure in a line, the pump is there to get the pressure back up. 3.2.4 The ECU The ECU receives, filters and amplifies the speed sensor signals and ascertains from them the degree of wheel slip and the acceleration of the individual wheels as well as the reference speed which is the best possible calculation of the vehicle road speed. Most of the systems use vehicle specific LSI circuits for this purpose. Fig 3.2 Anti Lock Brake Pump and Valves 3.3 WORKING OF ABS There are many different variations and control algorithms for ABS systems. We will discuss how one of the simpler systems works. The controller monitors the speed sensors at all times. It is looking for decelerations in the wheel that are out of the ordinary. Right before the wheel locks up, it will experience a rapid deceleration. If left unchecked, the wheel would stop much more quickly than any car could. It might take a car five seconds to stop from 60 mph (96.6 kph) under ideal conditions, but a wheel that locks up could stop spinning in less than a second. The ABS controller knows that such a rapid deceleration is impossible, so it reduces the pressure to that brake until it sees acceleration, then it increases the pressure until it sees the deceleration again. It can do this very quickly, before the tire can actually significantly change speed. The result is that the tire slows down at the same rate as the car, with the brakes keeping the tires very near the point at which they will start to lock up. This gives the system maximum braking power. When the ABS system is in operation we will feel a pulsing in the brake pedal; this comes from the rapid opening and closing of the valves. Some ABS systems can cycle up to 15 times per second. 3.4 TYPES OF ABS: Anti-lock braking systems use different schemes depending on the type of brakes in use. Referring them by the number of channels, that is, how many valves that are individually controlled and the number of speed sensors, we have the following:   i) Four-channel, four-sensor ABS This is the best scheme. There is a speed sensor on all four wheels and a separate valve for all four wheels. With this setup, the controller monitors each wheel individually to make sure it is achieving maximum braking force. ii) Three-channel, three-sensor ABS This scheme, commonly found on pickup trucks with four-wheel ABS, has a speed sensor and a valve for each of the front wheels, with one valve and one sensor for both rear wheels. The speed sensor for the rear wheels is located in the rear axle. This system provides individual control of the front wheels, so they can both achieve maximum braking force. The rear wheels, however, are monitored together; they both have to start to lock up before the ABS will activate on the rear. With this system, it is possible that one of the rear wheels will lock during a stop, reducing brake effectiveness. iii) One-channel, one-sensor ABS This system is commonly found on pickup trucks with rear-wheel ABS. It has one valve, which controls both rear wheels, and one speed sensor, located in the rear axle. This system operates the same as the rear end of a three-channel system. The rear wheels are monitored together and they both have to start to lock up before the ABS kicks in. In this system it is also possible that one of the rear wheels will lock, reducing brake effectiveness. This system is easy to identify. Usually there will be one brake line going through a T-fitting to both rear wheels. We can locate the speed sensor by looking for an electrical connection near the differential on the rear-axle housing. Chapter 4 IMPLEMENTATION OF ANTI-LOCK BRAKING SYSTEM 4.1 BLOCK DIAGRAM OF ABS On initial braking, the brake pressure is increased, the brake slip ÃŽÂ » rises and at the maximum point on the adhesion/slip curve, it reaches the limit between the stable and unstable ranges. From this point on, any further increase in the brake pressure or braking torque does not cause any further increase in braking force FB. In the stable range, the brake slip is largely deformation slip, it increasingly tends towards skidding in the unstable range. Actuator Desired Slip Controller Vehicle Dynamics Actual Slip Fig4.1. Block Diagram of ABS We model the ABS using Matlab/Simulink where in the various mechanical blocks are realized and mathematical models of the same are readily available in the Simulink library. The ABS simulation model follows the below shown control loop. The reference variable is the desired relative slip which is fed as an input to the system. The control system in our case is the wheel whose parameters like wheel speed are measured. The feedback path consists of the user defined equation which measures the relative slip of the wheel and the error is rectified at the initial stage. The model represents a single wheel, which may be replicated a number of times to create a model for a multi-wheel vehicle. Fig 4.2. ABS Control Loop 4.2 ANALYSIS OF ABS: For understanding the concept of ABS, we make use of the free body diagram of a wheel. We make use of the formulae for force and torque acting on the wheel. The below figure gives us a clear understanding about the forces acting on a wheel. The wheel rotates with an initial angular speed that corresponds to the vehicle speed before the brakes are applied. We used separate integrators to compute wheel angular speed and vehicle speed. We use two speeds to calculate slip, which is determined below. Note that we introduce vehicle speed expressed as an angular velocity (see below). . (Equal to wheel angular speed if there is no slip.) (1) Fig 4.3 Free Body Diagram of a single wheel (2) (3) is the wheel speed divided by the wheel radius. is the vehicle linear velocity. is the wheel radius. is the wheel angular velocity. We can also write (3) as (4) Where V is the vehicle speed, à Ã¢â‚¬ ° is the wheel speed and r is the radius of the wheel. From these expressions, we see that slip is zero when wheel speed and vehicle speed are equal, and slip equals one when the wheel is locked. A desirable slip value is 0.2, which means that the number of wheel revolutions equals 0.8 times the number of revolutions under non-braking conditions with the same vehicle velocity. This maximizes the adhesion between the tire and road and minimizes the stopping distance with the available friction. If an excessive brake torque is applied, the wheel will be locked, which means that it slides on the road surface but does not rotate at all. A locked wheel has no lateral stability and less longitudinal friction force, which is the ultimate force to stop the vehicle. Thus, a braking with a locked wheel will cause longer stopping distance and lateral instability. The tire force from the road surface causes the wheel velocity to increase, thus decreases the wheel slip. A high ÃŽÂ ¼ leads to a large tyre force and a low ÃŽÂ ¼ leads to a small tyre force. In the increasing part of the ÃŽÂ ¼-slip curve, an increase of the wheel slip leads to a larger ÃŽÂ ¼ and a larger tyre force, which reverses the wheel slip to a small value. However, in the decreasing part of the ÃŽÂ ¼-slip curve, an increase of the wheel slip leads to a smaller ÃŽÂ ¼ and a smaller tyre force, which causes the wheel slip to increase continuously. So, the peak point of the ÃŽÂ ¼-slip curve is criti cal. When a braking is initiated, the wheel velocity starts to decrease and the wheel slip starts to increase from zero. The wheel slip may stop increasing and start to decrease before the ÃŽÂ ¼ reaches its peak point. But if an excessive brake torque is applied, the wheel slip may go straightly to a large number, which causes the ÃŽÂ ¼ to pass its peak point and reach somewhere in the decreasing part of the ÃŽÂ ¼-slip curve. If the brake torque is not reduced quickly at this point, the reduction of the road friction force will lead to a rapid increase of the wheel slip and eventually to a wheel lockup. ABS tries to detect when this peak point is going to be reached and then reduces the brake torque properly so that a wheel lockup could be avoided. Fig 4.4. ÃŽÂ ¼-slip Friction Curve It appears to be true that maintaining the wheel slip at the peak point of the ÃŽÂ ¼- slip curve is ideal. However, the position of the peak ÃŽÂ ¼ point varies on the different road surfaces. In addition, stay at the peak point of the ÃŽÂ ¼- slip curve sometime may lead to a poor lateral stability. Thus, many control strategies define their performance goal as maintaining the wheel slip near a value of 0.2. This represents a compromise between the lateral stability, which is best at ÃŽÂ »=0 and the maximum deceleration which usually appears when ÃŽÂ » is between 0.1 and 0.3. 4.3 IMPLEMENTATION The friction coefficient between the tire and the road surface,  µ, is an empirical function of slip, known as the  µ-slip curve. We created mu-slip curves by passing MATLAB variables into the block diagram using a Simulink lookup table. The model multiplies the friction coefficient,  µ, by the weight on the wheel, W, to yield the frictional force, Ff, acting on the circumference of the tire. Ff is divided by the vehicle mass to produce the vehicle deceleration, which the model integrates to obtain vehicle velocity. In this model, we used an ideal anti-lock braking controller, that uses bang-bang control based upon the error between actual slip and desired slip. We set the desired slip to the value of slip at which the  µ-slip curve reaches a peak value, this being the optimum value for minimum braking distance (see note below.). Note: In an actual vehicle, the slip cannot be measured directly, so this control algorithm is not practical. It is used here to illustrate the conceptual construction of a simulation model. Fig 4.5. Simulink Model of the ABS In the above figure, the wheel speed, vehicle speed and the stopping distance are measured and the error value is fed back through the feedback path. Also, tire torque and the relative slip are fed as inputs to the wheel speed block. Notice that the model is a reference model which has its own internal block. Double click on the Wheel Speed subsystem in the model window to open it. Given the wheel slip, the desired wheel slip, and the tire torque, this subsystem calculates the wheel angular speed. To control the rate of change of brake pressure, the model subtracts actual slip from the desired slip and feeds this signal into a bang-bang control (+1 or -1, depending on the sign of the error). This on/off rate passes through a first-order lag that represents the delay associated with the hydraulic lines of the brake system. The model then integrates the filtered rate to yield the actual brake pressure. The resulting signal, multiplied by the piston area and radius with respect to the wheel (Kf), is the brake torque applied to the wheel. Fig 4.6. Wheel Speed Model for the ABS The model multiplies the frictional force on the wheel by the wheel radius (Rr) to give the accelerating torque of the road surface on the wheel. The brake torque is subtracted to give the net torque on the wheel. Dividing the net torque by the wheel rotational inertia, I, yields the wheel acceleration, which is then integrated to provide wheel velocity. In order to keep the wheel speed and vehicle speed positive, limited integrators are used in this model. After we build the ABS model in simulink, we have to configure the parameters related to simulation of the model. We need to specify that the signals are exported to the Matlab workspace where they are analyzed and results are viewed. This is done by checking the signal logging field in the configuration parameters option provided in the simulation tab. Fig 4.7. Configuring Parameters for the model We make a Matlab code which makes use of the inputs and outputs used by the simulink model and we plot the waveforms. 4.3.1 ABS Code h = findobj(0, Name, ABS Speeds); if isempty(h), h=figure(Position,[26 239 452 257], Name,ABS Speeds, NumberTitle,off); end figure(h) set(h,DefaultAxesFontSize,8) logsout.unpack(all); plot(Vs.Time, Vs.Data); set(findobj(type,line),color,[0 1 0]); hold on; plot(Ww.Time, Ww.Data); title(Vehicle speed and wheel speed); ylabel(Speed(rad/sec)); xlabel(Time(secs)); set(gca,Position,[0.1300 0.1500 0.7750 0.750]); set(get(gca,xlabel),FontSize,10); set(get(gca,ylabel),FontSize,10); set(get(gca,title),FontSize,10); % Plot arrow with annotation hold on plot([5.958; 4.192],[36.92; 17.29],r-,[5.758; 5.958; 6.029],[36.55; 36.92; 35.86],r- ) text(8.533,54.66,Vehicle speed (omega_v),FontSize,10) plot([7.14; 8.35],[43.1; 56.3],r-,[7.34; 7.14; 7.07],[43.4; 43.1; 44.1],r- ) text(4.342,15.69,Wheel speed (omega_w),FontSize,10) drawnow hold off h = findobj(0, Name, ABS Slip); if isempty(h), h=figure(Position,[486 239 452 257], Name,ABS Slip, NumberTitle,off); end figure(h); set(h,DefaultAxesFontSize,8) slp = logsout.slp.Data; time = logsout.slp.Time; plot(time,slp); title(Slip) xlabel(Time(secs)) ylabel(Normalized Relative Slip) set(gca,Position,[0.1300 0.1500 0.7750 0.750]) set(get(gca,xlabel),FontSize,10) set(get(gca,ylabel),FontSize,10) set(get(gca,title),FontSize,10) Chapter 5 RESULTS AND CONCLUSION After building the model, we simulate it using the options provided in the same Simulink window. 5.1 RUNNING THE SIMULATION 5.1.1 With ABS Press the Play button on the model toolbar to run the simulation. We can also run the simulation by executing the sim(FILE NAME) command in MATLAB. ABS is turned on during this simulation.

Brown v. Board of Education of Topeka, Kansas Essay -- Segregation Rac

Brown v. Board of Education of Topeka, Kansas On May 17, 1954 the United States Supreme Court handed down the Brown v. Board of Education of Topeka Kansas ruling. The supreme court’s ruling stated that separate was in fact not equal. The court ordered that all schools desegregate. This ruling had finally and once and for all put a stop to the dejure segregation of our nation’s schools that had existed since the time when African Americans were allowed to attend schools. This ruling was definitely one of the most significant legal victories in the history of the civil rights movement and possibly the entire twentieth century. It is viewed this way because â€Å"This movement rebuked centuries of government-sanctioned black inferiority† (Cohen p. 22) and most importantly it overturned the Plessey v. Ferguson ruling. The Brown decision breathed new life for the hope of America’s future, that all children regardless of race would be able to receive an equal education. In addition, the NAACP had gained momentum and had big plans to continue the civil rights movement in other areas. Their agenda included housing segregation and employment discrimination. Thurgood Marshall and other members of the NAACP’s law team were confident in their success and believed that it would only be a short period of time of five years before school segregation would be totally eliminated. Sadly, desegregation was not achieved as rapidly and as smoothly as anticipated. In fact, many people claim that in many areas today the schools are resegregating. According to Ted Shaw, head of the NAACP’s legal defense fund, â€Å"we are currently resegregating, and no none seems to care† (regression on integration).

However, the thing that disappoints me the most is that after conducting more in depth reading than I previously had done, I still have no answer of how to fix the problem. I realize that it would be foolish of me to realistically think that I could fix the problem with what little I have studied the subject in this class, but out of all the reading I have done, I could not find a single article that actually gave a solution of how to fix the problem other than continuing the battle in the courts. This is the part that this is so disheartening to me. There is a real problem and I want to fix it, but apparently it is going to be a long struggle to get things back on track. Works Cited 1.

Benito Mussolini :: essays research papers

Benito Mussolini was born on July 29, 1883 outside the village of Dovia di Predappio in the Northeastern Italian province of Forli. He had one sister and one brother. They always fought and argued over little petty things with each other. His sister name was Edvige and his brother’s name was Armaldo. His mother Rosa Malteni was a well respect and appreciated schoolteacher. His father Allesandro Mussolini was both a blacksmith and a committee socialist. He received his name "Benito" from the Mexican Revolutionary Juarez. Benito grew up as a delinquent, disobedient, and did not have any manners. He was a bully to the other children around him. He would get into numerous of fights with other children. Benito Mussolini was brought up in one the poorest regions in Northeastern Italy. When he was in school, he always kept to himself and very quiet. He wasn’t a class clown, never cried or rarely laughed. He always sat in the back of the classroom and read a book. He rather do that than play with the other children in his class. He got kicked out his first boarding school. When he was growing up he was surrounded by many political philosophies. There was anarchism, socialism, and others. Both Benito and his father Allesandro had very bad violent tempers. When Benito grew up, he became a teacher in an elementary school in his nearby town; he spread the party of doctrine. He was an editor, Fascist leader, laborer, soldier, politician, and revolutionary. He also became a socialist. He graduated at a teacher training school in Forli, Italy. Then he moved to Switzerland to find a better place to work. When he was in Switzerland, he got in trouble with the law for fighting and vagrancy. So he decided to move back to Italy but in Trent. When he returned he worked for a Social Newspaper Company and wrote several literacy works. The newspaper was called "La Lotta di Classe (The Class Struggle). The towns’ people loved his newspaper. He made the editor of "Avanti" (forward); it was published in Milan. When Benito wrote some ignorant and cruel suggestions and ideas in the newspaper. So the he was fired. He then decided to created his own newspaper. He called it, "Li Popolo d’ Italia" (The People of Italy). He hoped the war between Italy and Turkey might lead to collapse of society that might bring him to power.

Essay --

Kidneys are very important organs. Their main responsibility is to filter harmful toxins from the blood, which are then excreted in the urine. The urine then flows through the ureters and into the bladder. When the bladder is full, the sensation to urinate arises and the urine is emptied through the urethra. Sometimes the crystals that are found in urine bind together and become big enough to develop into a kidney stone. I have yet to encounter anyone who has had this issue, but I have heard from other people that kidney stones can be very painful. Knowing the flow of urine and how small ureters are gives me chills just thinking about the pain someone might have to endure. Kidney stones differ in size and shape and can either be smooth or pointy. They can be the size of a sand particle or the size of a golf ball. There are even some stones that can fill the entire kidney; these are known as staghorn stones. Infections are the usual culprits for this type of stone. Calcium, very common in dairy products, is what the majority of stones are created from. Other chemicals tha...

Theatre-Director’s Role

The director is the most important person in the play because without his visions the actors would have no purpose and nothing would go on. Without the director all would be at loss in the theatre. The director is the one who tell everyone what to do and installs the fear into the cast and other to perform at their best at all times. The director is the person who all the actors and stage crew and everyone tries to impress and they will always be on their best behavior while the director. I would want to be the director because everything is dependent on you and you are the one who calls the shots and I will maintain order on the set. The director is the one who knows the whole play and has to get the performers to perform and to make the show run as smoothly as possible. If the actors or stage coach were to get out of line or not do their job then the director would heard about it and not be do happy about it. The preparation for the director is a major issue. Many hours of perfecting the acting according to the script takes a strain when you have to account for everything that is going on. A director must having coping skills and still be enough and authoritarian to have respect from all the members of the cast. For me personally, I would have to learn how to work with people instead of getting mad and not wanting to work through problems that might occur during rehearsal and the whole production in general. The work and preparation that needs take place is tremendous, but the director has to put so much pre meditated work in that is not seen by many people, but its truly eveudent in the final production.

Relationship Between Public and Private Policing Essay

Abstract This paper will explore the historical relationship between public and private policing. It will also discuss how the relationship has changed in recent years. Relationship Between Public and Private Policing Since the terrorist attacks that struck inside the heart of our country on 11 September 2001, civilian law enforcement agencies have been busy performing not only their regular duties of crime prevention and response, but also taking on a large number of homeland security functions and all of this during a time when local, state and federal budgets are ever tightening. Similarly, private security institutions are under comparable pressure to carry out their traditional duties to provide protection of information, property and people, as well as sharing the additional duties of homeland security. Despite the fact that public and private police organizations share the same ultimate goal of protecting the public, they do not have a long history of working well together. Security officers have historically been looked down upon by law enforcement personnel. Some police feel that there is a definite lack of pre-employment screening, certification, training, standards, and regulation of security officers. Other police officers feel that security personnel receive insufficient training, especially those who carry weapons. Another perception that some police have is the view that security officers are those who couldn’t make it as law enforcement officers so they settled for a career in security. Meanwhile, some security officers view police as snobs who do not have an understanding of the range of capabilities, functions and resources offered by the private security field and thus fail to appreciate the role they can play. Private policing really got its start in the U.S. in the mid-1800s with the  foundation of the Pinkerton National Detective Agency in Chicago Illinois by Allan Pinkerton, the first man to be appointed as a detective in the Chicago Police Department. Since the federal government did not have personnel that could follow criminals across state lines, and local police personnel were ill equipped to handle the job, the Pinkerton Agency was hired to deal with criminal gangs (BSIS, n.d.). The company also performed many duties that are now handled by federal and state law enforcement agencies such as guarding railroads, conducting criminal investigations, and providing security advice to banks and other businesses. â€Å"Policing is not necessarily the exclusive dominion of government, but rather a ‘service’ that could be assumed either by public or private agencies† (Elizabeth Joh, 2004). According to the Department of Justice, Bureau of Justice Statistics, in 2000 th ere were 797,000 law enforcement officers employed in the United States by local, state and federal agencies. In comparison, private security organizations throughout the country employed roughly two million security officers (National Policy Summit, 2004). With these numbers it only makes sense for there to be a cooperative relationship between public and private police agencies. Joining the capabilities of the two sides would benefit each profession and greatly enhance the protection level that could be afforded to the citizens of this country. For example, the public police agencies usually receive more current threat information, while the private police agencies tend to maintain control over the areas or facilities that are considered vulnerable to attack. It has been estimated that â€Å"85 percent of the country’s critical infrastructure is protected by private security organizations† (National Policy Summit, 2004). One factor that I believe has had a positive impact on improving relations between public and private police agencies is the crossover of personnel. Many times when law enforcement personnel at the local, state or federal level retire from their agencies, they tend to take on positions of employment with in the private police field as Directors or other higher level positions due to the degree of their experience. These personnel maintain their contacts from within the law enforcement realm which can facilitate opportunities for much needed training and education of security officers, as well as increased probabilities for the sharing of information between agencies. Another aspect which is closely related is the hiring of  off-duty police officers to perform private security functions and details. Many companies feel that hiring an off-duty police officer to perform private security functions can be an effective crime deterrent when there is a visible police officer presence. Most public police agencies allow their officers, with advanced permission from the department, to work security duties or details while wearing their police uniform and even operating their department issued police vehicle. Another advantage of hiring off-duty police officers is that they maintain the power of arrest and use of force at all times, whether on or off-duty. So when a crime occurs, you already have a police presence on scene that can handle the matter. There are even some police agencies which are actually commercializing their services. According to Massimiliano Mulone, â€Å"police organizations are selling the services they provide to private individuals/organizations, from renting off-duty police officers to offering training for the private security workforce† (2012). There are some negative aspects to hiring off-duty police personnel to perform private security duties. First of all, the average police officer will charge at least twice as much as the hourly wage a typical security officer will be paid. Another issue to consider is the fact that some police officers will not perform some of the more menial tasks that a regular security officer would be required to perform as par t of their normal duties. Additionally, since the police officer is not depending on this part time job as a primary source of income, they may not put the same level of devotion into completing the tasks of the position as a security officer that is performing this job as their primary source of employment. Furthermore, â€Å"recent research finds that that fatigue associated with overtime and outside employment may contribute to accident and injuries involving police officers and may lead to more citizen complaints† (James Brunet, 2008). Another issue of concern is that while a police officer is performing in an off-duty capacity as a security officer, they can be called away from these duties to assist on-duty officers with incidents that occur nearby. Lastly, a company that hires off-duty police personnel to work in a private security capacity must be aware that there are unique legal issues to be considered, such as when Miranda warnings should be used and under what cir cumstances searches may be authorized. In almost every major city throughout the country, shopping malls, hospitals, apartment complexes, university campuses and housing associations depend on various private police organizations for security. Evidence shows that private policing has considerably decreased crime rates in neighborhoods across the country. â€Å"After the ‘Grand Central Partnership,’ an organization of over 6,000 businesses, hired a private security force to guard a 70 block area in the midtown Manhattan area, crime rates dropped by 20 percent after two years, by 36 percent after three years and 53 percent after five years† (Kai Jaeger and Edward Stringham, 2011). Another example of this statement is the â€Å"introduction of private policing by Critical Intervention Services in a low-income area of Florida that reduced crime rates an average of 50 percent† (Jaeger and Stringham, 2011). The greater the number of private property establishments that can be covered by private police agencies will allow the public police officers to concentrate their efforts on responding to the more significant crimes. The reality is that government agencies are being required to do more with less, cut budgets and ultimately cut the number of public police officers that are needed to protect the public. On the other side of the issue, private security organizations are constantly growing and providing more professional and better trained security officers in order to stay competitive in the private policing field. In many instances it is getting harder to distinguish between the public and private police officers and the overall duties they can perform. By combining the efforts of the two spheres of responsibility it would greatly benefit both sides, as well as provide a higher level of protection for the citizens of this country.

Harnessing the Science of Persuasion Article Critique/Analysis

Harnessing the Science of Persuasion Article Critique/Analysis I chose to critique the article â€Å"Harnessing the Science of Persuasion† by Robert B. Cialdini. As an undergraduate I was planning on a profession in the medical field, and I enjoy exploring how the science and business worlds correlate. In this article, Cialdini describes six scientific/psychological factors that contribute to enhancing one’s ability to increase influence on others. I interpret that pure motives are the main success factor in building influence at the underlying theme of Cialdini’s principles. I can only be as persuasive as I am sincere in my desires to know, and help others. In this paper I will overview some of the principles that Cialdini presents, and apply them to my strategy for my personal, and professional advancement. Liking/Similarity Though the conscious mind may seek diversity, there is an undeniable human behavioral trait to associate with people who are â€Å"like me†. At first glance this principle suggests that we should stick to doing business with people who look, act, believe similarly to how we do and avoid other people because we will not be successful with them. I feel that I have always had an ability to relate to people, whether it is in line at a Motley Crew concert, or in an executive meeting. I believe that humans are more similar than different. The skill is identifying common ground quickly in interactions, because everyone is in a hurry. I have attempted and will continue to apply this principal in my business interactions by showing a little personality in the first few seconds that I interact with my customers. The trick is to do this without being perceived as smug or an apathetic. I can say a quick line from a song that is stuck in my head, and say â€Å"sorry I’ll try to focus better throughout the remainder of this transaction;† or asking a detailed question about a project that the customer is working on. It is important to adjust the tone, and etiquette to the person, and situation that is presented. I have found that when the person that I joked around with comes back, they seek me out to help them more often than not. Like all of Cialdini’s principles these techniques ill only work if I am sincerely interested in the person that I’m interacting with. Humans are very skilled at detecting apathy, so if I have to fake it, it’s better to not to try. Consistency/Commitment I am a pretty witty, creative guy, as such I am fairly successful with the principle of liking/similarity as stated above. I honestly struggle with the principle of consistency. Consistency, as discussed by Cialdini, describes influencing others to firmly commit to do what you desire of them. This principle is mostly applicable in my interactions with my co-workers. I place such a high emphasis on relationships with people that I often leave the opportunity open to be taken advantage of. I have many responsibilities that go unaccomplished if I consistently do the job of a co-worker. In today’s business culture, hierarchal flowcharts are decreasing in authoritative efficacy, and behavior is influenced more strongly by persuasion skills. Getting people to buy in and commit to it because it is in the best interest of the customer, the company, and the person you are trying to convince is the goal of consistency. There are levels of commitment. A person can mentally commit, verbally commit to the issuer of the request, or publicly commit in front of peers. Each increased level of commitment results in higher likelihood that the person will keep their word. The challenge in applying this principle for me is to not come across as overbearing, or not willing to lead by example. I will apply this principle by discussing with my co-workers their desires to do a good job. I will ask those whom I direct to explain their thoughts about how we should best serve our customers, and apply their suggestions as best I can to procedural changes. I will also better describe the process from the perspective of people who work primarily inside the store, so that we can all better understand and assist each other. The success of consistency, perhaps even more so than the principle of liking, is dependent on motives. If it is perceived that you are more interested in throwing your authority around than working for the common good, resentment and non-compliance will result. I will avoid resentment by expressing sincere gratitude, and praise for a job well done. I will also show a willingness to go outside, and help when appropriate. I have read a few articles about enhancing persuasion in business, and to be honest, most of them come across as phony ways to trick people to do what you want. Cialdini certainly has some elements of convincing people that they want to do what you desire, but he introduces the idea that these techniques only really work if you have pure motives. I really like the idea that being an effective/persuasive leader starts with being an honest/authentic person.

Commercial Tourism

Tourism is an activity of visiting new places for the purpose of leisure. There is domestic or local tourism where people visit places in their own home country while in international tourism people visit other countries apart from their home country. The basic activity of tourism in the past years had been to see the wonder of nature and the aesthetic beauty of the natural environment and the different rich biodiversity that is unique to each and every country.However in the recent years the activity of tourism has taken a different course and people no longer visit places to see the natural environment but go to see the modern improvements characterized by commercial ego. This work will closely examine the commercialization of tourism in America and its influence on the American culture. The point of reference to a typical commercialization of tourism is the Mall of America that has over the years taken tourism to a different level. Tourism in the Mall of AmericaThe mall of America in Minnesota was established back in the year 1992 and is the largest undercover shopping center in the world. It occupies an area of 78 acres of land and has all types of business activities aimed for entertainment purpose. It has over 500 shops with Macy's Blooming dales, Nordstrom and the Sears which are giant American shops. This alone attracts millions of people every year to America and also the Americans who frequently visit the place more often than any tourist attraction sites like the national parks, game reserves and museums.There are nightclubs, restaurants, cinemas and children ride games. There is also a theme park inside the Mall called the Camp Snoopy that occupies seven acre space of land in the park and an underwater Aquarium that is a home for over 300,000 sea species that can be seen face to face by visitors. The mall is a commercial site as its entrance is free just like a market but individuals are charged on the services rendered inside the Mall. There is far much for the tourism that used to be in the world and America in particular.The people's culture has changed towards tourism and people nowadays are visiting modern sites designed with high level of technology to boost tourism in the Malls. The true definition of the culture of touring has completely been commercialized. In America for example, people prefer going to places with modern facilities for maximum comfort. This is demonstrated by the increase in the number of classic hotels surrounding the tourist attraction sites such as the beaches, national parks and other unique places with natural aesthetic.The improvement in modern technology has also contributed to the change of culture for the Americans. The effect of globalization has in particular influenced the theme of tourism in several parts of the world. The internet has been used intensively to advertise the different sites across the globe and most of them are aimed at the beautiful beach resorts and five star hotels nei ghboring the tourist sites which have given tourism a commercial perspective. In Minnesota, there are several tourism offers that have been favored through a partnership with the Malls of America.In the real sense the idea of tourism has been outdone by the luxurious modern facilities that have become a major concern for many people in the American culture. The people in America have changed their attitude towards touring in the natural environment in the preserved animal orphanage and prefer to visit modern Malls with a wide range of modern facilities as well as animals in special beautiful cages. People tend to tour to the places that have beautiful holiday packages.In most occasions, the holiday packages in the United States have been accompanied by several money making activities. The car hiring companies are in the increase in the name of tourism as well as credit vouchers for the luxurious Hotels in the city for tourists. Tourism is no longer a natural adventure; people often go for holiday in places with a variety of packages for maximum comfort during their holiday but not in a natural environment with a lot of adventure. The American's culture associated to tourism was initially a matter of adventure with nature.The visiting of the natural scenes in the wild has been taken by other adventurous activities such as mountain climbing activities, sporting activities such as skiing, skating which have a commercial attachment. However these changes might be changing with the culture of the Americans and the generations have taken different perspective of tourism (Melanie, 2006). Cuisine on the other hand has participated in the change and commercialization of tourism, the variety of foods in the American culture is a major attraction to the tourists in America.People in the US visit different websites to find an ideal package for their holiday in the worlds best tourist sites but the first consideration is the presence of the beautiful luxurious hotels to fi t for their holidays. The cuisine also advertised in the company of the tourism destination has a factor in the choice of the place of visit. Conclusion The American's culture has changed adversely in the world of tourism. These changes have come from the past love for the physical natural environment to modernism.The majority of the people in America are looking forward for a more comprehensive place to spend their holidays. The idea of modernized shopping malls, with modern lifestyles and modern food has been given preference over the natural biodiversity that is a major tourist attraction in most countries. As a result of this, several countries across the globe has designed modern tourist facilities in their countries to encourage tourists. The Malls of America is one of the best malls in the world and has tourism impact (Melanie, 2006).

US Democracy Essay Example | Topics and Well Written Essays - 1250 words

US Democracy - Essay Example The question how democratic is democracy in U.S may seem challenging to a lay man but it is clear from the U.S constitution that the states practice democracy in almost all their dealings. However to some extent America system of governance has failed to adopt some of the some of the innovations and modifications in the democratic systems and ideal. The United States constitution allows the common citizens to participate in various democratic processes such as election and taking part in referendum in case there is any. However to some extent the American democracy gets dilute day by day with more of her power Washington. The states are becoming more republic consolidated government. The "politically correct" and "historical revisionists" have soiled United States with restrained but disparaging autocracies that have extremely dented our free democratic people. Politicians use the term democracy when they need something from the publics, and they use the term republic when they do no t need something from the citizens. It is political system and where the legal force is regulated through given and enumerated powers. For instance, the United States Constitution, and predominantly the Bill of Rights, was premeditated to limit governments part to what United States’ founding forefathers saw as governments utmost vital functions. The main functions were to reserve individual liberty and defend private property. Moreover, Persons differ in their perception of a limited government, nonetheless, one common understanding is that a limited government is one that imposes just ample taxes to deliver for state defense and police security and then stays out of publics undertakings. As an example, a limited government is one that does not distress itself with issues such as what sallies should employees get from the jobs they do, retirement investment schemes of

The Individual and Society Essay Example | Topics and Well Written Essays - 750 words

The Individual and Society - Essay Example The individual has violated a type of social norm referred to as injunctive norm. Injunctive norms commonly refer to what is approved or disapproved by the culture, and they encourage behavior through the informal social sanctions. In other words, injunctive refer to the perceptions of what it is supposed to be done (De Cremer, Murnighan and Van Dick 69). For example, the individual has violated of what it is perceived to be done, not to litter the environment. The society in general, requires that the environment is kept clean and the incidences of littering are considered to be against the social norms. Thus, the individual has violated the social norms that require the environment to be kept clean. In USA, there are several organizations and interest groups that have taken the initiative of keeping the environment clean through methods such as litter prevention. Keep America Beautiful, Inc. (par. 6) asserts that littering is a personal choice. In other words, it is an individual behavior to choose to litter on the ground. 83 percent of the litter is disposed properly meaning that most people hold the notion that littering in the wrong places is not good. Thus, litter prevention is a social norm that is accepted by most people living in the USA. It will not be proper for an individual to litter in the wrong places in USA. As stated earlier, choosing to litter (that is, to litter on the ground) is an individual behavior. According to Keep America Beautiful, Inc. (par. 6), 81 percent of individuals litter intentionally; through methods such as flinging, dropping or flicking. It further states that individuals tend to litter in environments already littered. Some of the individuals believe that litter prevention is not their responsibility. These people lack sense of ownership for beaches, walkways, parks and other public places. They believe that someone will pick

Transformational corporate leaders are born not made Essay

Transformational corporate leaders are born not made - Essay Example or is of the view that transactional leadership is the most common form of leadership where the focus is on the exchange that occurs between leader and his sub-ordinates. Politicians who promise â€Å"more development,† managers that reward their employees with â€Å"promotions† and classroom teachers, which grade students on their completed work, engage in transactional leadership. According to the definition of transactional leadership, â€Å"it refers to the leaders who guide or motivate their followers in the direction of established goals by clarifying role and task requirements† (Robbins, pp. 44-51, 2001). However, â€Å"transformational leader are those who inspire followers to transcend their own self-interests and who are capable of having a profound and extraordinary effect on their followers† (Robbins, pp. 25-31, 2001). As the definition implies, transformational leaders have a boarder vision and go one-step further than transactional leaders. These people actually make an effort to engage and develop and connection with their sub-ordinates or followers and then work towards increasing their motivation levels and making them realize their full potential. More importantly, during this process not only the leader transforms his followers but also finds a transformation in him as well. Mahatma Gandhi is one of the most cited examples of tr ansformational leadership. He influenced the Hindus of the South Asia, raised their hopes and demands, made them felt their needs and rights and during this process he ultimately found himself transforming from Mohandas Karamchand Gandhi to â€Å"Mahatma Gandhi† (Tichy & Devanna, pp. 85-97, 1990). Other examples include A. G. Lafley of Procter & Gamble, Andrea Jung at Avon, Jim McNerney of Boeing and Orin Smith at Starbucks, Steve Jobs founder of Apple Computer, Mary Kay Ash from Mary Kay Ash cosmetics and others (Daft, pp. 41-49, 2007). A study conducted with five corporate leaders, which have performed like transformational

Conservatism and Neo-Ottomanism of the Turkish Political System Essay

Conservatism and Neo-Ottomanism of the Turkish Political System - Essay Example Additionally, in contrast to the modernization movements of many of the governments in the post Ottoman Turkey, the Conservative ideology that has been adopted by the Turkish political system during the past decade (2002-2013) is largely opposed to the westernization of Turkey. For example, the conservatism themes of the Turkish governments within the last decade (2002-2013) has been characterized by a new form of nationalism, marked by attempts to conserve Turkish national values â€Å"ulusalclk† as well and social values such asexuality, family values, gender relations and religious values in the face of the current rapid globalization and perceived Europeanization (Yavuz, 2009). This has been particularly evidenced by the de-westernization and re-traditionalization of the Turkish society that has been witnessed in the country since the Justice and Development Party lead by Recep Tayyip ErdoÄŸan came to power in 2002. In a recent interview with Financial Times Newspaper, T ayyip ErdoÄŸan described his party’s vision and ideology as seeking to establish a conservative democracy in Turkey which is attached to the traditions, customs and values of the contemporary Turkish society.Finally, despite the fact that the consecutive AKP led governments in Turkey since 2002 have always rejected any association with Islamism or political Islam as part of their ideology, the main ideology of the Turkish political system under the leadership of AKP has been primarily characterized by institutionalization of Turkey’s traditional and religious values
