Systems Case Study Essay Example for Free

Systems Case Study Essay The subway network can be split into 4 main sub systems, those being design, manufacturing and maintenance, operation and customers. The design process initially involves designing the desired rail network, however once the entire system in in operation the design sub system involves the constant re design of features and parts caused by arising issues as well as updating the system to use newer technologies. This subsystem requires many disciplines of engineering including electrical which designs many of the electrical features including the main power system responsible in powering  of the overall system [1], civil which designs structures such as stations, bridges and tunnels underneath the city [2] and mechanical which is involved in the design of railway vehicles [3]. The manufacturing and maintenance subsystem involves the building of everything required for the system to function from manufacturing the trains themselves to constructing the network of rails, tunnels and stations they travel through. This is all continuously maintained to assure it is reliable and fully functioning to allow for the system to be operated. One important engineering discipline involved in the manufacturing subsystem is manufacturing engineering which with the aid of many other engineering disciplines is able to turn raw materials into new products such as train carts, railway tracks etc [4]. The operation process is the subsystem that the customers or users of this system rely heavily upon. The operation of this system involves using all the parts of this system in order to fulfil its function of transporting its users. The operation process involves constant monitoring of the system in order to allow for a schedule as well as maintain safety and assure the system is functioning correctly. This all requires many operators such as traffic controllers, drivers and conductors. Software Engineering is a very important part of the operation process as it is responsible for developing software to track rail carts, display arrival times and operate automated train supervision [5]. The final subsystem of this system is the customers or the users. This system includes all the users of the rail system and as the main purpose this system is to provide customers with transportation this subsystem like every other relies heavily upon all the other subsystems in order to allow the rail system to function. The main subsystems or the systems key elements interact strongly with each other and rely heavily upon each other in order for the system to function. The whole purpose of the rail transportation system is to create a more efficient, convenient and more simple way for people to travel to and from a desired location. A high level of intelligent communication and interactions between the subsystems allows the system to meet its desired outcomes. As transportation is the users need there is a strong interaction between the customers and the operation subsystems. In order to meet customers’ needs the operation of this system needs to be working efficiently, this requires all the parts involved in this subsystem to be running proficiently as any dilemmas within this subsystem can impact the customers causing problems such as delays and accidents which can lead to many complications with the system as a whole [6]. In order to meet customers needs there is a strong interaction between the operation and the manufacturing and maintainance subsystems. In order to operate the system there initially needs to be parts that have been manufactured such as tracks, stations and trains. However once the system is running constant maintenance on parts as well as the manufacturing of new parts are needed in order to allow to allow for the operation of the system to run efficiently [4]. Problems in the manufacturing and mainanace system can furthur lead to operation issues that can have a devastating impact on the customers. To assure that apropriate parts are made the manufacturing and maintainance subsystem relies on the design subsystem. This subsystem is extremely important in assuring that features of the system are designed  apropriatly eliminating any potential risks during the manufacturing and operating stages [7]. Finally the customer subsystem has strong interaction between all the other main susbystems. Actions and the behaviours of the customers infuluences and changes the ways all the subsystems interact. More users require more operation which leads to the need of more manufacturing, maintainence and design. Less users can potentially reverse this effect. In order to create a sustainable system the key elements need to rely heavily upon each other [8].

Julius Caesar Essay: The Development of Mark Antony :: Julius Caesar Essays

Julius Caesar:   The Development of Mark Antony  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚      In the play Julius Caesar by William Shakespeare, the author writes the Character â€Å"Mark Antony† very well. In the beginning of the play Antony is a very good friend of Caesar and watches out for him. He treats Caesar as a father with great respect. Antony is very loyal to Caesar and he does everything in his power to make Caesar happy, for example while he runs the race in the beginning of the play, he touches Caesars wife so that she may be fertilized.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   After Caesar is killed, Antony becomes very mournful and outrage by the treachery of the conspirators that killed Caesar. Antony asks for just to a speech at Caesars funeral and Brutus grants him that one wish. Antony is a very intelligent man and he has the ability to manipulate a crowd with his speeches. For example in Act 3 During Antony speech he says   But Brutus says he was ambitious;   And Brutus is an honourable man.   He hath brought many captives home to Rome   whose ransoms did the general coffers fill:   Did this in Caesar seem ambitious?   When that the poor have cried, Caesar hath wept:   Ambition should be made of sterner stuff:   Yet Brutus says he was ambitious;   And Brutus is a honourable man.      By this it shows that Antony is intelligent and has courage for he mocks Brutus and his accusations. And it shows how he can manipulate the crowd by telling of Caesars wonderful accomplishments.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Antony then shows his anger towards the conspirators by getting the mob to release their anger by rioting and going out and killing the conspirators. Antony then starts a war against the conspirators and when this war starts Antony changes from the people’s hero to just a normal greedy leader. His hate for Brutus grows over time and with that hate grows greed. Antony starts thinking more about his wealth then about the people that he is supposed to be caring for.   In Act 5 Antony expresses his feelings towards Brutus before they go into the battle that will decide who is the rightful ruler of Rome.   Villains, you did not so, when your vile daggers   Hack'd one another in the sides of Caesar:   You show'd your teeth like apes, and fawn'd like hounds,   And bow'd like bondmen, kissing Caesar's feet;   Whilst damned Casca, like a cur, behind   Struck Caesar on the neck.

Best/Worst Experience in Modern Communication Essay

l rather than physical presence or written/printed channel. The best experience I’ve had communicating electronically was via e-mail. Last year in March, I went back to Israel to visit my family for a few weeks. Doing so each year is very hard on the family I leave behind, taking care of the everyday life without me around. My husband and I got to talk on the phone once or twice a day, but never too long due to the facts of the surrounding aspects (such as: noise, people that came to see me, and so on). Our landlord decided to sell his house and gave us one month notice as was written in the contract. We only had one month to find another place to live with 3 kids, while I was in Israel for the next 2 weeks. This was a very positive experience for my husband and I. It enabled us to communicate with each other and our realtor via the e-mail. If not for the e-mail options, I couldn’t have done what I succeed to do. I e-mailed each day to our realtor, knowing I can’t communicate with him with the 10 hours difference between us. He sent me houses to look for in the e-mails, and I e-mailed him what I liked and what not. The e-mail availability gave us the option to manage the issue from a distance, without being scared and cancel the visit with my extended family. Channels are the mediums that carry messages between communicators. (Dobkin-Pace, 2006). Worst experience I have had communicating in an electronic/computer communication channel rather than physical presence or written/printed channel. It happened in Canada 5 years ago. I was working in the Jewish community center as an event planner for the center. I was doing my daily tasks when suddenly I looked at my inbox and saw that I have an e-mail from the CEO. I looked at the e-mail and saw that she decided to cancel an event that I worked so hard on, with no reason. To me it felt so wrong and with no feelings. I felt so upset and thought to myself that this should have been done face to face and not through e-mail. She might have had her own reasons to why she did it, and she might have done the right decision.

Sample Undergraduate Psychology Essay - 1591 Words

SAMPLE UNDERGRADUATE PSYCHOLOGY ESSAY NB This is not a perfect essay. It was graded at 60% (A 2.1) and the bibliography is missing! Drawing on Freudian and Attachment Theories assess the Relationship between early years experiences and criminality. Psychological theories have attempted to explain the reasons for and how criminality occurs. The psychoanalytic perspective involves two major theories - Freuds theory of the Sexual Stages of Development and the Theory of Attachment purposed by Bowlby (1947). These theories conclude that there is an association between the formation of personality in childhood and that of future criminal behaviour. The Freudian theory of development suggests that we go through several stages of development†¦show more content†¦In addition, the majority of boys interviewed (93%) came from homes where there was lax parental supervision and they were allowed to make their own decisions. Therefore, these findings suggest that the attachment or bond between a child and their main care giver is important in the formation of personality and the development of their moral beliefs. This research also identifies how the parental use of punishment may be a cause of delinquency and anti-social and criminal behaviour. However, later research was to show this conclusion to be incorrect (e.g. Schuck, 1974). Later studies have infact indicated that parental permissiveness was a cause of juvenile delinquency and aggression (Lipton, Martinson, and Wilks, 1975). This latter point is a criticism of the Freudian approach to parenting skills. Freudian theorists argue that parents should be permissive and allow children to work their way through problem situations without the parent causing internal trauma in the child by being too strict in their expectations with their child. The Freudian theory believes that healthy development will be encouraged through a warm parent-child bond, whereby the child is helped through interactive talk to uncover and reveal the unconscious conflicts that are inhibiting the childs progression. Therefore, Freudian theory suggests that anti-soc ial or criminal behaviour is heavily influenced by early years experiences and the childs ability to progress through the sexualShow MoreRelatedSexism Is Prolonged Cruel, Or Unjust Treatment?1430 Words   |  6 Pagesto â€Å"examine the essay content to see if themes related to ambivalent sexism were spontaneously generated when women described their gender-based experiences† (Fields, Swan, Kloos, 2009).
