Relative Strength and weaknesses of modeling, simulation and prototyping. Strengths: †¢ It helps to get an overall structure for a complex system. Creating a model involves the system designer and the clients. Therefore it is suitable to have an idea of what the end product will turn out to be. †¢ Modeling and simulation allows the designers to compute values for different inputs which is difficult to achieve in the real world. †¢ It is cost effective. If the model and simulations are reliable it cuts down on the money required for testing. Weaknesses: †¢ In making a model the requirements of the client or the main problem to be addressed may be misplaced. †¢ The models and simulations may not be accurate in all conditions in reality. †¢ The models can be too simplistic to solve problems involving complex problems †¢ Designers may over rely on models on simulations than actual testing. Problematic assumptions in modelling, simulation and prototyping: One the examples I would like to point out is the flight which crashed on August 16th 1987, the plane was a Mc Donnell Douglous MD-80 operated by the Northwest Airlines. The reason for the crash according to the NTSB was that the aircraft was not set up for take-off properly by the crew due to failure in adhering to the pre-flight checklist. [1] Another factor which contributed to the mishap was the failure of the flight takeoff warning system which did not indicate to the flight crew that the flight was improperly set up for takeoff. This failure of the takeoff system was due to the loss in power to the warning system due to circuit failure. Why is this a simulation error? It is because in the flight simulator this warning system flashed a light when the system was down but in the actual ... ...ight budget and timeframe, this led to engineers relying more on models and simulations than actual testing. Models like the Radar-terrain interaction and Dynamical control effects of pulse-mode propulsion were not properly validated due budget constraints. This reliance on software models and simulations may have caused the MPL to be destroyed. These tools can be used but their limitations should also be known. In order to minimize these failures a decisive decision should be taken early in the development stages by experts and experienced system architects and engineers this will minimize the errors made in the finishing stages. Risk assessment should be carried out whenever analysis are based on models and simulations without being validated by actual testing. This will help reduce the over reliance on models and simulations by the engineers. [4] References: 1.

Note on the Character of Angulimala

Ans: Angulimala was a thief, a vicious robber, a murderer without mercy, who made villages into non-villages, families into non-families, slaughtering them and cutting off and wearing their fingers in wreaths around his neck. As he wore the garland of fingers, he was called Angulimala. The word â€Å"Angulimala† means ‘a garland of fingers’. In the region, where he lived, he was called the second ruler after the king. People were afraid of him. They obeyed him as they obeyed the king. People were so much scared of him that they never dared to travel alone. They even were afraid to travel in groups.Angulimala was a strong man and a great runner too. No one could escape him. He even caught elephant, deer, horses, even a group of acrobats from the circus. Even though Angulimala was a vicious robber, a merciless slaughter, there was a little goodness inside his heart which even he himself did not know. When Buddha explained a simple truth of life, he was pierced by th e words. His goodness, the softness of his heart emerged with great force. A sudden change came to his heart. At once he surrendered himself to Lord Buddha. He buried his evils with his swords and weapons and became a monk.After that Buddha sent him to the city for alms. There Angulimala witnessed the poor condition of the people; he could feel how much he had tortured the people. When he entered the city for the next time he was also tortured by the people very badly. As Buddha said, that act made Angulimala sinless and a pure monk. Then Buddha gave him his own begging bowl and robe and left him. Angulimala came in this way to understand the joy of freedom. Thus, though Angulimala was a cruel, merciless villain, he was later transformed into a sinless, soft hearted monk with full of goodness inside him.

I am performing in a Play called Trojans Essay

It is an old Greek legend but has been re-written and modernised as a play by Simon Adorian. It is about a siege of the city of Troy by the Achaeans. It was over Princess Helena who Prince Paris stole off the leader of the Achaeans, Menelaus. It is shown that it is set in modern times by the spray painting by my character, Prince Cassius, at the beginning and when Laocoon talks about the burnt out cars in scene 3. It uses a Greek style in the way it is written by using a chorus, the youths, although in Greek plays these parts would usually have been sung rather than acted out. The other play I have studied is â€Å"Oedipus the King†. This is a Greek play that is set in Greek times. Greek theatre differed very much from today’s theatre because there was no scenery. It had a raised section on the back of the stage, on which actors stood in order to be seen better. Any murder that took place was committed off stage, but with the chorus filling in the details. The dead body was the brought on the stage on a flat low trolley with wheels to show who had been murdered. The performance styles of the two plays do not differ too much from each other. The chorus still exists in Trojans through the youths, rather than an off stage singing group. Both plays have women in the positions of power and status. Trojans is a modern play with modern cultural themes portrayed through the characters. This would appeal to a modern audience more readily than Oedipus. Oedipus would have been performed in ancient times. In the Greek theatre only male actors were allowed. Also no women were allowed in the audience so it would have been a play by men for men. Trojans now has a mixed audience and therefore explores the issues women have as well as men. This is shown by the peace protestors, who are mainly women, and the youths, who are mainly men. The way plays were portrayed to the audience in Greek times was solely through the chorus, who described the scenery and who was who. There were only three actors in the play, therefore character changes were shown through wearing different masks. The chorus would also have to explain the weather and the theatres were open air and plays were performed in daylight because there was no lighting equipment. Things could also be conveyed through a character called the messenger. He would describe off stage action in long and elaborated speeches. This is closely shown in the character of the spokesman, who describes the off stage battles. As Trojans is set in modern times, different lighting effects and scenery can be used. This mean that there is no need for a passive chorus, but to maintain the Greek feeling Adorian added in an active chorus through the youths. They give transitions between scenes when it is required. The themes in the two play are quite similar. They both revolve around the royal families. With Princess Cassius fronting the peace protest in Trojans, and King Oedipus having been prophesised to kill his father, and does. They are both tragedies. King Oedipus finds out what he has done and that he has fulfilled the prophecy. The tragedy in Trojans is that the Achaeans win in the end. The characters in the two plays are similar. The chorus in Greek plays, although not strictly characters, are very closely similar to the youths by applying transitions between the scenes. Also the Messenger in Greek plays is very similar to the Spokesman, who provides elaborate and vivid word pictures of what is going on in the city and what has happened in the various battles with the Achaeans. The royal families are not similar however due to the fact that the real tragedy at the end is not to do with them as it is in Oedipus, it is to do with the youths. Reflecting on this I will play my character as flippant, perhaps a little ignorant and nai ve. The attitude he takes to the Royal family is that of disrespect and he has a bit of a love hate relationship with them, as they are his family. I would play him as strong headed and wilful due to the fact that he is fronting an active campaign against the war.
