Capacitors Using Charge Sensors - Lab Report Example The application of various capacitors with different capacitance also makes it important to determine unknown capacitance besides voltage calculation by using the equation (Q=CV) Six different capacitors were obtained from the lab and their capacitance measured. A parallel circuit was created composing of 1.0ÃŽ ¼F capacitor and 0.1ÃŽ ¼F capacitor (making 1.1ÃŽ ¼F. A second capacitor of 1.0ÃŽ ¼F was charged into 5V. The charged capacitor was then touched to the 1.1ÃŽ ¼F capacitor (uncharged) in the circuit. The 1.1ÃŽ ¼F was again discharged. The aforementioned steps were then repeated with a 0.1ÃŽ ¼F capacitor used in place of 1.0ÃŽ ¼F as the charge transfer capacitor. Then, instead of discharging the 1.1ÃŽ ¼F capacitor the 0.1ÃŽ ¼F capacitor was recharged to 5.0V followed by reconnecting it. The 1.1ÃŽ ¼F capacitor was then charged to 5.0V followed by sharing its charge with uncharged capacitor that has unknown capacitance. The final reading was made from the voltmeter and then used t o arrive at the unknown capacitance by use of the equation Q=CV. The unknown capacitance was then directly measured from the digital voltmeter. A parallel-plate capacitor was constructed through inserting a waxed paper in between aluminium plates. The construct was then pressed together by placing on top a 1.0kg weight. A charge sensor was then mounted with a 0.01ÃŽ ¼F capacitor. The combined capacitance of 0.01ÃŽ ¼F capacitor, together with the charge sensor, was then measured by using the digital voltmeter’s capacitance capability.

Operation Analysis w5 discussions - Essay Example Graphical solutions in linear programming have limited number of decision variables. The technique of LP plots constraints on graph paper and then identifies the feasible region that is represented by the constraints. The objective function is then drawn and used to identify optimal points in the feasible region. However, graphically, linear programming can only be done in one two variables. Thus, the maximum number of variables in LP model is two. However, it can be done in more than three variables using special algorithms. Business managers use linear programming models to come up with concrete and measurable performance improvements. The kind of decisions that are arrived at using LP models represent the optimal solutions or decisions that are possible with the given constraint variables at the disposal of managers. For instance, the optimal decision would be the maximum profit that a business can generate using available limited resources or the minimum costs that the business can incur to produce products in order to maintain its current maximum level of profits. Therefore, LP can help managers use available limited resources effectively, reduce costs, improve profitability, and reduce risks among other key benefits. Simplex method is a special algorithm that is computer based used to find optimal solutions to linear programming problems that contain thousands of constraint and decision variables. The simplex method uses iterative algorithm to find solutions to optimization problems. The method uses or provides data on slack variables, which represent unused resources and opportunity costs or shadow costs useful in sensitivity analysis. Therefore, simplex method is an effective and efficient method that overcomes the limitations of the linear programming model to find solutions to problems of optimization by ending at an optimal solution by jumping from

Fuzzy Concepts Discussion Posts Essay Example | Topics and Well Written Essays - 500 words

Fuzzy Concepts Discussion Posts - Essay Example Apart from recruiting civilians into various factions of the army, the posters were also used to raise war finances through the liberty bond scheme. The reason I’m fuzzy about these posters is that they lied to innocent civilians. The government through posters gave the people a false sense of pride in their countries and they readily accepted to risk their lives. Many were comical and casual and did not reflect the true situation that was at hand. This may be the main reason why many civilians willingly put their lives in an unworthy cause that saw many of them lose their lives. For instance, there is a poster where a young lady wishes that she was a man so that she could join the army. Such a poster was strategically used to invoke the feelings of all men to partake on the war. Some even have explicit undertones like ‘I Want You’ that could only be described as either vulgar or having poor satirical taste. I have to agree with you that Lord Kitchener’s poster was the most copied poster at the time. At the onset of the war, Britain’s army comprised of mostly the trained forces and the country needed to recruit more people into the army. They therefore invented the poster propaganda that was soon copied by other nations. Most British posters had the symbol of St. George slaying a dragon- which represented German. And the messages ranged from honor and pride for the nation to shameful mobilization of civilians. For instance, the poster with the message: ‘Daddy, what did YOU do in the Great War?’ is using children to blackmail their parents. The American approach was not open, direct and blatant as the British posters; however they all served the same purpose. In America, they were chiefly used in raising war funds. The main theme in these posters was portrayal of money as an important ingredient in military

Building a Website Essay Example for Free

Building a Website Essay The information on the internet cannot be retrieved without the use of interface domains called websites. These are the main access portals where a person may be able to acquire information online. There are several basic steps in building a website. Such process will enable a user or an institution to acquire a definite space in cyberspace. According to BuildWebsite4U, there are at least three basic steps in establishing a website. The first of which is the formulation of ideas which will eventually put contents to a web domain. There are no general rules as to what contents are to be used. However, having a good and catchy interface for the visitors will always count to make a website efficient. Upon the identification of the website content, the optimization of the key parts of the website follows. The key phrases and words of a website influence all the mechanisms in leading visitors to the site. These search engine optimization qualities serve as doorways in which people will be able to access the web portal. The next phase in building a website is the establishment of its technical aspects. First, the web design should be constructed in a way that can achieve full exposure to internet surfers. The templates and how the contents are arranged in a page are of utmost importance. Next, a good and well developed HTML codes should be used. These website builder languages serve as the primary tool in executing the template plan of the web design. In case the owner wants to enhance the visual appeal of the website, additional web graphics features can be integrated to the web design using HTML codes. The last segment in constructing a website involves the activation of the address to become a part of a very wide world of cyberspace. This process will start by selecting domain names. Apparently, it is the most important aspect in the entire process of creating a website. A domain name will serve as the address of the website on the internet. A web developer can get these domains by registering to any of the reliable web hosts which can accommodate the files of the web portal. Works Cited BuildWebsite4U. 2002. How to Build a Website.

Describe the physical and economic factors Essay Example for Free

Describe the physical and economic factors Essay Bournemouth is Dorsets largest city. It has grown in size since the early 1800s to a population over 160,000 today. There are various reasons why Bournemouth is desirable and has attracted so many people. Bournemouth seems to have a certain charm that other British characteristics that many other seaside towns fail to offer. Physical: Bournemouth is situated on a Jurassic world heritage coastline meaning that it offers a beauty that other coastlines lack and people are aware of its beauty. Many new families are drawn to the area as they believe that it is a good area to raise a family, and that it holds good and secure prospects. Although not the vital factor when families relocate, people like to feel safe and have nice surroundings. Bournemouth has these; the city is approximately 21 miles away from the New Forest. The middle class families that choose towns such as Bournemouth like the fact that they are so close to beautiful pastures and cycle paths through the forests, as Cities such as London and Manchester do not offer such environmental diversity. Bournemouth is keen on keeping the building of new buildings as low as possible, encouraging developments to take place on unused brownfield sites to try and worsen the costal squeeze. Bournemouth wants to keep its rare assortment of coast, countryside and city developments. However, there are some new developments in the town; the Bournemouth Pavilion Gardens is a i 59 million project that will see a nine screen cinema, 15 restaurants and over 30+ shops using unused land to create the development. Economic: Unlike many other costal towns, Bournemouth has been fortunate enough to see an economic boom take place. The service sector in Bournemouth has taken off; more residents have seen employment in banking, finance and tourism/ leisure. JP Morgan, a large and well respected American ban has chosen Bournemouth to have a large office on the edge of the city, employing over 4000 people. With the likes of JP Morgan setting up offices here, it means that other banks such as Barclays and Abbey Life have chosen to have offices in Bournemouth. These companies also find Bournemouth desirable due to the university, with graduates finding well paid jobs in these footloose industries. This has some affect on stopping a brain drain that other seaside towns have experienced, with Bournemouth having a surprisingly bottom-heavy population for a British seaside town. Transport in and out of the city has greatly improved since the 1980s, in the late 80s the rail links were improved shortening the length of journeys to London to just 2 hours. This could mean people decide to commute from Bournemouth to London. However, the airport has helped Bournemouth economically develop, with links to cities all over Europe it will continue the cycle that JP Morgan by setting up office in the town, due to its proximity to London and links to Europe. Being the 3rd best airport in the world by The Telegraph newspaper will give it some extra prestige too. Although the tourist trade in Bournemouth is not what it once would have been; now a lot more day-trippers are visiting the town. People might be staying the New Forest and visit Bournemouth for a day. Alternatively, people are using the train links from London to Bournemouth to visit for the day too, leaving early in the morning and returning in the evening. They are not spending as much as people who would have once holidayed here for the week, but are still contributing to the upkeep of Bournemouths economy. In conclusion, Bournemouth is a crowded coast due to having career prospects that entice the young to stay in the town. There is not as big a case of a brain-drain that other coastal towns may experience. With over 62% of the population being under the age of 49 it means the town is not just a retirement town that other costal towns such as Walton- on- the Naze have experienced. People inwardly migrate here due to the towns environmental diversity. Some middle class families find that raising children in a town such as Bournemouth is a safer environment than a city. Bournemouth is only 2 hours from London, offering cheaper house prices, a sluggish but achievable commute to London and its proximity to the national park the New Forest have all contributed to Bournemouth being a crowded coast in the 21st century.

Dangers of Dual Relationships in Therapy

Dangers of Dual Relationships in Therapy Often, people who seek the help of a therapist are vulnerable in a number of ways, and the unique relationship of client and therapist is built on a great deal of trust and openness where a number of issues are exposed. This situation can often leave a patient or client feeling more vulnerable than ever before, and depression, anxiety, and other mental health concerns can easily cloud a clients judgment. Because the client-therapist relationship is a relationship of power, it is more important than ever that therapists do not give into seduction or sexual attraction that may exist for a client, and that sexual relationships with clients and patients not be allowed to develop. Although some studies have been done on the existence of client therapist sexual relationships, it is evident that many of the results of these surveys are unreliable due to the nature of the situation. Even when confidentiality is assured, many therapists are fearful of the repercussions of being exposed and are reluctant to divulge such information. Still, these studies confirm that sexual relationships still often do occur between therapists and clients, more frequently in male practitioners than females. Furthermore, these studies have also revealed that these kinds of relationships can be further detrimental to clients and patients who seek the help of professional therapists. Sexual relationships between counselors and clients has existed probably since the beginning of time, being noted as far back as the fifth century B.C., when the Hippocratic Oath originated, stating, â€Å"In every house where I come, I will enter only for the good of my patients, keeping myself far from all intentional ill-doing and all seduction, and especially from the pleasures of love with women and men.† However, recent studies and even court cases have confirmed that this phenomenon continues and in many cases, is further detrimental to the mental health of the clients who enter into these types of relationships. For clients who are dealing with issues related to domestic violence, abuse, rape, or incest, the abuse of trust and power that occurs with sexual client-therapist relationships can increase feelings of trauma and psychological distress, often triggering symptoms of post-traumatic stress disorder. Even in clients who are not dealing with these kinds of issues, increased depression and anxiety can occur, and a patient who has been involved in a sexual relationship with a therapist is often more likely to attempt suicide and further resistant to additional treatment. Also, studies have revealed that sexual relationships between therapists and patients are frequently associated with cognitive dysfunction, feelings of emptiness and isolation, an impaired ability to trust, increased feelings of guilt, confusion regarding boundaries, and suppression of anger. Although these types of symptoms are not noted in every client who has been involved in a sexual relationship with a therapist, many of these symptoms were seen as common in clients who had engaged in this type of relationship. In short, therapy is the most successful when boundaries and trust of the client are not violated and a professional relationship is maintained, and in nearly every jurisdiction, it is the responsibility of the therapist to maintain this professional relationship. In fact, the legal consequences for therapists who do enter into a sexual relationship with a client can be severe in many states. In order for therapists and other mental health professionals to maintain their professional licenses, most states not only mandate that there be no sexual relationships with clients, but also that there is no sexual relationship with a former client as well. While in some states the requirement is that the client has not been a patient for at least two years, in others the guidelines stipulate at least five years. In addition, the mental health professional may be obligated to prove that the relationship is not exploitative in nature and that the client is fully capable of making their own decisions regarding the relationship. For therapists and mental health professionals who do engage in a sexual relationship with a client, the penalties can be severe. Not only can a therapist lose their professional license for such acts if the relationship is discovered, but they can also be sued for malpractice and violation of trust in many instances. Maintaining a professional relationship at all times is not only in the best interest of the client and their mental well-being, but also in the best interest of the practitioner and their professional reputation.

Artificial Heart Devices Essay -- essays research papers

Artificial Heart Devices In its never ending pursuit of advancement, science has reached a crucial biotechnological plateau, the creation of artificial organs. Such a concept may seem easy to comprehend until one considers the vast knowledge required to provide a functional substitute for one of nature's creations. One then realizes the true immensity of this breakthrough. Since ancient times, humans have viewed the heart as more than just a physical part of the body. It has been thought the seat of the soul, the source of emotion, and the center of each individual's existence. For many years, doctors and researchers left the heart untouched because they thought it was too delicate, too crucial to withstand the rigors of surgery. However, the innate human desire to achieve brought about the invention of the artificial heart. The potential for such inventions are enormous. According to the American Heart Association, there are between 16,000 and 40,000 possible recipients of artificial heart devices under the age of sixty-five. If perfected, it would enable us to save thousands of human lives. In considering the full impact of artificial heart devices on society, we must not narrow our thinking to include only the beneficial possibilities. There exist moral, ethical, and economic factors that accompany these new innovations to humanity. Who will receive these brilliant inventions? Obviously not all of the patients will get transplants, so selection criteria must be established. The high price of artificial heart devices and their implantation will eliminate some candidates. Unfortunately, this is not fair. The rich, in essence, can buy life, whereas the poor are abandoned to die in a diseased state. A thorough analysis of the implications of the implantation of such devices reveals not only selection and economic consideration, but mortality and ethics as well. Many contest that it is simply wrong to tamper with the ways and creations of nature. By prolonging life through unnatural means were are defeating natures foremost tenet of the "survival of the fittest." We are preserving the weaker gene pools and contributing to the deterioration of the human species. These and other considerations play a vital role in determining the artificial transplants actual benefit to the contemporary world and the world of tomorrow. A... ...evices for the heart will definitely have a great impact on society. This can be classified in two major ways: financial problems and population problems. Of course, increased use of artificial heart devices in medicine is going to increase the financial burden on society. The potential gains will be substantial when the lives of many productive individuals can be saved. The extent of the financial burden depends largely upon the number of patients who benefit from the artificial valve, the availability of the device, and improvements in its efficiency and dependability. In the long run, worldwide utility of the artificial valve technology would increase the world population. Overpopulation is already the root of many of the world's crises. The many debates concerning artificial heart implantation as a medical technique each have their own significance, and each deserves thorough consideration. Before we rush headlong into complete employment of the devices in medicine, we must evaluate the moral, social, ethical, arguments. Hopefully we can reach a decision that blends all of the aforementioned considerations into a harmonious existence, working to the maximum benefit of society.
