Business law - Case - Essay Example But he has neglected the aesthetic aspects of the treatment and thought that causing a burn to the patient is negligible as part of saving the life of the patient. In that sense the doctor was culprit of neglecting certain critical things in his profession. If the surgery was unavoidable at that juncture, probably the doctor’s actions could have been justified. On the other hand, there are no such worries in declaring the ECR instrument manufacturer as the major culprit in this case. This manufacturer has sold defective products in the market which caused damages to the users. It is the responsibility of the manufacturer to test the quality of the product fully before introducing it in to the market. He should ensure that his product may not cause any damages to the users. No product manufacturer has the right to sell defective products in the market. The specifications and usage instructions of the product should be given to the users by the manufacturer and the manufacturer is responsible for any malfunctioning of the product provided the users use it exactly as per the instructions given by the manufacturer through the product manual. So the manufacturer of the ECR instrument is 100% responsible for this crime and need to be compensated Karl for that. Apart from the doctor and the ECR manufacturer, the hospital management is also responsible for Karl’s agony. The management purchased cheap quality products and took the risk of using it in the treatment of patients. It is the responsibility of the management to ensure the quality of the products they purchased before testing it on others. So, in my opinion, Karl can consider suing against the hospital management also. Anaesthesiologist and the nurses have nothing to do with this case. The duty of the anaesthesiologist is confined to the anaesthesia alone. He has nothing to do with the usage of

Design and Implementation of a Single Phase Inverter Circuit Essay Example for Free

Design and Implementation of a Single Phase Inverter Circuit Essay Inverters are used to produce constant or variable frequency AC output from a DC source. These inverters can be used for AC applicatio n like driving an induction motor. Such type of inverters in present world are used largely in renewable energy systems to convert DC to AC, example is a PV system where there is a requirement of such type of inverters which can power AC systems such as an induction motor (IM). It is required to produce a pure sinusoidal waveform for the proper functioning of the IM drive. This can be done by incorporating pulse width modulation (PWM) techniques. Technique used in generating a Pulse width modulation is that of the comparison of reference signal which is a sinusoidal waveform as required at the output and a triangular or carrier signal of high frequency. The next section (Section 2) will give a brief detail about the power switches used in the inverters. Section 3 gives the study in detai l of single phase half wave and full wave bridge. In section 4 a detailed discussion about PWM technique is done. This section  also gives the circuit diagram required to generate the PWM using microcontroller. Section 5 shows the development of the swit ching control in details starting from the opto-coupler to the derive circuit. The bootstrap circuit is detailed in section . This is followed by a complete block diagram of the single phase inverter along with its control circuit in section 7. A detailed study on a practical blanking time circuit is done in section 8, followed by the circuit for the opto -coupler and the driver required in the presence of blanking time circuit, this can be seen in section 9.

Artificial Intelligence: Where does it fit? Essay -- Technology Artifi

Artificial Intelligence: Where does it fit? Machines in the future will not be able to differentiate between man and machine, and neither will humans; except that machines will be active: working, learning, developing new technology. Humans on the other hand, have no choice but to watch from our glass boxes because machines have become so advanced and we would only interfere. Maybe the future won’t look exactly like that, but truthfully, computers will reach human intelligence someday. They have already surpassed our calculation abilities and our speed of processing information. But we can still hold on to our intelligence for now. Artificial intelligence, the science and engineering of making intelligent machines through intelligent programs, is not just about modeling human behavior. It’s more about making life easier and better by developing new tools with advanced capabilities. Artificial intelligence, like technology, advances rapidly as time moves on. It needs to be worked on before considered satisfactory, let alone perfect. Computers have many similarities to humans like neural impulses to digital technology or being programmed to function in a certain manner. A computer is given commands and specific outputs for corresponding commands. Humans are taught to act or not act in specific ways. We have automatic responses such as fear, hunger, and happiness. We’ve been programmed to react differently to various stimulants. Great progress has been made by developers of artificial intelligence, but there remain large gaps between humans and machines. Physically, humans have bodies with senses. Machines could have bodies— like robots—but they are still unable to sense the physical world and react to it. H... ... If computers overtake the workplace, professionals sacrifice their dignity: there will no longer be an emphasis on skill level because the computer makes the decisions. Mistakes would be inexcusable, although humans are not flawless. Humans would not be credited for achievements because computers will have done all the computation, planning and presentation. The value of a human life will decrease as the computer climbs the corporate ladder. If humans continue to do what we do best, look out for ourselves. We’ll realize that artificial intelligence should be made to supplement humans, not to replace them. We should not rely on computers as much as we rely on our instincts and judgments. If we allow machines without bodies and without minds to take over our world, what would our purpose be? Would we have existed just to bring artificial intelligence about?

Decision-Making Models Essay -- Decision-Making Model Analysis

Decision-Making Models General assumptions create the foundation of a person's reasoning. Imperfections with a supposition can create the opportunity for a skewed perspective in a person's reasoning process (Paul & Elder, 2002). The process of choosing one course of action over another is commonly known as decision making. Consciously or unconsciously, people make decisions on a daily basis founded on one or more of the various decision-making models (Sullivan, n.d.). This paper examines how I apply various decision-making models in the workplace to generate accurate workload estimations in my career. The Qualitative Choice Theory also known as analogous reasoning uses past experience to help an individual make decisions. A resolution is derived by looking at what has occurred historically and basing the decision on the expected outcome (Arsham, 1994). The Program Evaluation and Review Technique (PERT) methodology is a decision-making model that uses a mathematical formula established on realistic, pessimistic, and optimistic estimates to provide an accurate estimate of the most likely amount of time to complete a project (â€Å"Critical path analysis & pert charts,† n.d.). Building on the analogous methodology, the parametric decision-making model looks at one small piece of a project, estimates the amount of time required to complete the particular section of the project, and multiplies the smaller piece times the number of total pieces (International Society of Parametric Analysts, 1999). The Monte Carlo simulation is a technique that makes use of computer models to aid in making decisions in intricate circumstances (Grambow, n.d.). My duties at work often require that I provide estimations for the level of effort required for projects I am working on and I employ all three of the aforementioned decision-making methodologies. More often than not, I rely on the analogous model drawing on my experience as a subject matter expert to create time estimates for small projects. Drawing on more than 5 years of programming experience, I am able create realistic estimates of the level of effort required to complete a small project. I use this methodology when asked to estimate simple text changes to the user interface for Web pages I maintain. For example, a client has just requested a change to the welcome page of his Web site and has committed to provide text... ...Retrieved June 20, 2005, from The University of Baltimore Web site: http://home.ubalt.edu/ ntsbarsh/opre640/partXIII.htm Bassham, G., Irwin, W., Nardone, H., & Wallace, J.M.

History of Broadway Essay

There have been many debates on whether or not Broadway musicals are considered â€Å"serious† art forms. People feel that a musical can never be taken seriously if the character is always singing sporadically, which is very unusual in real life. However, musicals have been around for quite some time now, many musicals are being adapted into major motion pictures, many children are raised on the famous Disney musical cartoons and everybody( whether they’ll admit it or not) has seen at least one musical in their lifetime and are able to sing some of the songs from it. It seems that musicals have made an impact on society but yet are still not taken seriously. The history of musicals dates back to the Greeks. It is a common known fact that the Greeks incorporated song and dance into their stage comedies and tragedies as early as the 5th Century B. C. Some used existing songs but it is known that Sophocles wrote his own. The Romans are also known for taking the Greek musicals and expanding on them. The Romans liked the idea of musicals so much that they attached metal chips to their shoes, creating the first tap shoes, so that there would be more focus on the dancing throughout the play. Of course musicals and the idea of telling stories through song and dance really became popular through the Renaissance era. During the 1700’s the two main types of plays were ballad operas and comic operas. Many people think that musicals evolved from operas however if you follow the history of musicals and operas you will learn that it is the other way around yet operas are much more respected than musicals. Musicals came to America during the mid-1800’s as saloon shows. They were also known as variety shows and consisted of everything from clowns, singers, dancers and chorus girls. In Low Life: Lures and Snares of Old New York (Farrar, Strauss, Giroux, New York, 1991, p. 92), historian Luc Sante, claims that variety shows were born in Manhattan’s Bowery saloons during the 1840s. One of the first and most famous variety houses was Koster and Bial’s on West 23rd Street in New York City. The variety shows were very distasteful and were later cleaned up and renamed vaudeville then in the 1900’s the shows were cleaned up even more and were then known as minstrelsy. While the minstrelsy shows were much cleaner than the original variety show they would still be considered extremely raunchy by today’s standards. Musicals later came to take the form of the misunderstood form of Burlesque performances. Burlesque shows became popular and kept America entertained from 1840 through the 1960’s. Many people identify burlesque with strippers or scantily dressed women. The burlesque shows however covered many topics of interest from Shakespeare to spoofs of the famous operas of the moment. In 1860 Burlesque made its appearance on Broadway with Lydia Thompson’s British burlesque troupe and their first hit entitled Ixion. It became clear that respectable people would pay lots of money for a sexy performance. The theatre group would use popular songs of that time and parts of operas to perform too which made some of the audience try to say made the Burlesque show more classy and easier to relate too. Soon the offended audience members began to raise their voices in protest of the performances saying that they were extremely inappropriate and tasteless. This of course only made people more curious about the performances and the crowds began to grow for the show. With the success of the shows people began to copy them and bring them back to their own communities. The majority of the managers and choreographers were women and finally women were beginning to gain respect in the theatre business. Men quickly began to see the success and start their own shows. The point of the shows were to hint at the idea of the women being naked and to show as much skin as was considered acceptable. The Burlesque shows, while being popular, were considered to be the lowest form of theatre, many of the actors would move on to vaudeville shows which were considered to be the top of the line where if a vaudeville actor would appear in a Burlesque show it was considered a step down and the actor was labeled as â€Å"washed up†. Burlesque soon took on comedy routines and would make fun of the current issues that the middle and lower class were dealing with. However in the 1920’s there began a raid and the police felt the need to shut down all of the Burlesque shows which was a major hit to the Manhattan society where most of the theatres were at the time. While the Burlesque scene was popular musical comedies were beginning to rise without the help of the nudity factor. The musical comedy was born on Broadway between the years 1878-1884 by the famous producers Edward (Ned) Harrigan and Tony Hart. Harrigan would write the lyrics and songs with some of the music he had taken from his father and add them to plays that would feature characters and situations that the everyday lives of New York’s lower class. They had one particularly famous bit entitled â€Å"Mulligan Guard’s March† which started in San Francisco and was quickly spread all across the country and reached New York where it ran for over a year in the most popular theatres. With the success of their short bit they expanded into a 40 minute performance which was greatly accepted and kept playing for a month which was considered a good run for that time. Their show became so popular that it started a seven year run of different shows with Harrigan directing, producing, performing and writing the scripts and lyrics. Their shows ran with much success on Manhattans downtown streets and overpopulated theatres. People quickly saw the success and began to try to create their own versions of this new style known as musical comedies. Some had success but were quickly forgotten or overlooked with Harrigan and Hart’s success. The more light-hearted and â€Å"cheesy† musicals began to pop up all over the Broadway scene in 1940. The Broadway producers felt that with America at war and people still suffering from the Depression audiences just wanted to be entertained and no longer wanted to see their troubles and everyday situations acted out on stage because they were no longer comical. There were still a few comedies left however, one of the most popular being This is the Army a comedy which spoofed the army life. This particular play had a huge success in America and also had successful run in London. This is the Army became so popular that they even made a motion picture out of the play which earned over $9 million and donated to the Army’s Emergency Relief fund. The 1940’s were filled with famous musicals all with the hopes of just being pure entertainment and losing the idea that only the most artistic performances would be well received. Two of the most famous musical writers in the history of the business made their debut during this time, Richard Rodgers and Oscar Hammerstein II. Rodgers and Hammerstein were friends in college and both agreed that the best way to approach a musical was with the lyrics first, which was rare for the time. When the two were ready to debut their loved musical Oklahoma the Theatre Guild was bankrupt so the two took the major decisions in their own hands. They took some major risks one being to not open with a big catchy theatrical number and the other being to cast smaller unknown actors instead of the guaranteed success of the more popular actors of the time. The play was something that had never been seen before; it was a well rounded well written musical. On opening night in New York the show however was not sold out, since there were no major known stars, however the show quickly became a huge success. The success of Oklahoma changed the quality of musicals forever. It was soon realized that musicals could contain more than just â€Å"cheesy† dance numbers; musicals could contain drama, comedy and all around quality acting. Future musicals had higher standards and required better and more talented actors. The actors had to be skilled dancers, singers and actors. There was a lot of talent discovered all over the theatre community during the 40’s while everybody tried to compete with and follow the success of Oklahoma, however most of the talent was quickly forgotten. The 1950’s were soon open the musical community and show tunes were considered the main source of entertainment. Even the smaller musicals that did not have the most talented actors could be very profitable because the audience hoped to discover another winning team like Rodgers and Hammerstein. The fantastic duo were still ruling the musical world of Broadway, at one point they had 4 successful musicals running at the same time. In 1959 one of the most famous musicals of all time was created and praised, The Sound of Music. Everybody loved the music and the story and it was an immediate success, however it is also remembered as their last great success together as Hammerstein died just a few months after it opened which brought the end of their ruling. The 60’s and 70’s also had some great success in the musical worlds with the idea of bring rock music to the stage. In the 60’s show tunes could not be found in musicals and were replaced by edgier rock songs. The 60’s are of course known as the years of sex, drugs and rock ‘n roll and those ideas were put into story lines and portrayed on the stage. The 70’s had two major hits with Grease and The Wiz. However, the 70’s ended on a bad not for musicals because many people were tired of the shoddy performances being produced and their change in taste of music. There were some other great musicals that were produced in the 70’s but unfortunately they went overlooked. At the end of the decade revivals were beginning to pop up with famous actors playing the major roles in the musicals to boost up ticket sales. In 1980 the success of Broadway was revived with the huge success of Cats. The success and word of Cats spread all across the world and totally revived the spirit of the musical theatre. Many American composers debuted works after the success of Cats but sadly many failed. One of the biggest failures, Carrie, made its debut in 1988 which many considered the death of the Broadway rage of musicals. The main source of entertainment was now and movies and nobody paid much attention to Broadway anymore. Broadway however had one major hit left in The Phantom of the Opera. Andrew Lloyd Webber gave Broadway one last major success which is still running today. The Phantom brought in a new crowd and sold tickets at outrageous prices that the audience did not mind paying for at all, they also spent ton of money on the souvenirs. The 90’s saw a pretty bad drought in musical success except for the mid-90’s when it seemed like musicals were back with the success of Rent, Chicago, Cabaret and Bring in Da’ Noise, Bring in Da’ Funk. The success carried into 2000 and is still working it’s was on a comeback with a hot streak. With the huge success of Chicago being adapted into a major motion picture with huge stars like Rene Zellweger, Richard Gere, Taye Diggs and Catherine Zeta-Jones a new interest and spark was ignited in musicals. The theatre has also seen success recently with The Lion King, Hairspray, Aida, The Producers and Mamma Mia!. Musicals have overseen many changes and has a great history of success and failures just like any other type of theatre. As stated in the beginning many children are raised on musicals and grow up surrounded by music yet musicals are not seen as serious pieces of art. While the most popular musicals are the entertaining ones that don’t deal with any major issues that doesn’t mean that they can’t be serious as well. There are many types of musicals but why does that make them less important? Should comedic plays be seen as less artistic than dramatic pieces? Musicals have just as an important background and history as plays so I feel they should be viewed just as valuable to our society as any other piece of theatrical art. While it may be unnatural for a person to just burst out into song throughout their everyday life I don’t think it’s that far of a stretch if it did happen. How many times are we reminded of a song we hear earlier that day and sing it in our head? The only real difference between musicals and everyday life is that when we do sing our songs throughout our lives they aren’t always originals, everybody around you doesn’t join in and automatically know every word and we don’t have perfectly choreographed dance numbers to go along with them, however if we did have all that I think it would make life a lot more exciting and interesting. I am personally jealous of musicals for those reasons and wish they were given more respect.

Biodiversity

Biodiversity Biodiversity Recently, the environment has been facing a lot of challenges resulting from the increased human activities such as farming and construction of the infrastructures. These activities have led to the imbalanced ecosystem. The environmentalists have continued to agitate for the need for humans to understand that the ecosystem is in a very dynamic setting, which is composed of different types and classes of living things. These living things are either directly or indirectly responsible for the survival of each other, and it is, therefore, important that they all exist. This write up addresses the various roles of people in ensuring the preservation of the areas threatened by the human encroachment. The balancing of different environmental concerns and the need for the U.S global participation in environmental conservation is also discussed. According to Narasaiah (2008), human encroachment is the inversion of part of the environment so that beneficial activities like farming and mining can be carried out. It has since threatened certain regions of the earth, thus, leading to the need for people to take up active roles in educating the rest of the human population on the importance of preserving the life of other living things. The innovation of environmental-friendly technology should also be encouraged, so that activities like mining and farming are done in a manner not likely to interfere with the ecosystem. In addition, the governments and private organizations should come up with protection programs, which can help preserve the regions threatened by human encroachment. These may include the formulation of preservation strategies such as; the creation of botanical gardens, seed banks, and zoos. Moreover, the governments should declare some human activities like cutting down of trees illegal if done without legal permission. The government should also carry out identification and protection of the biological hotspots. That is, the species rich regions to be protected so as to assist in maintaining the ecosystem at a balance. Finally, people should be advised to change their pattern of consumption and development activities so as to reduce the levels of environmental destruction (Kearns, 2010). The issue of drilling of oil in the Arctic has generated a controversial debate with a section of scholars supporting it while others have emphasized on its illegality. However, other scholars have come up with a compromising position noting the need for the consideration of both the long-term economic arguments and the habitat protection arguments. They have thus called for the need of environmental friendly methods of drilling as a compromised choice (Kearns, 2010). Narasaiah (2008) notes that many environmental conservation groups have come up to help in saving the rain forests. Some of these groups are in the United States of America though they operate internationally. Even, though, many people have questioned why the U.S is interested in the environmental conservation, in the other countries, it is important to note that every part of the worlds ecosystem contributes to the balancing of the whole earths ecosystem. In conclusion, it is important to note that a balanced ecosystem benefits the whole life forms on earth and so should be a responsibility of everyone.
