System to Control Cars Anti-lock Braking System

System to Control Cars Anti-lock Braking System Giving reasons for your answer based on the type of system being developed, suggest the most appropriate generic software process model that might be used as a basis for managing the development of the following systems: A system to control a cars anti-lock braking system You could use Incremental or Spiral process models as safety is critical so you need a method that a lot of checks and balances at each stage. Incremental development is broken down into increments with each increment delivering part of the required functionality, where the user requirements are prioritized and the highest priority requirements are included in early increments however once the development is started, the requirements are frozen but can be used in later increments. Spiral process is represented as a spiral rather than as a sequence of activities with backtracking where each loop in the spiral represents a phase in the process. There are no fixed phases such as specification or design but loops in the spiral are chosen depending on what is required. Both Incremental and Spiral would achieve the goal of managing development for the cars anti-lock braking system however incremental development would be the most suited since it takes the allows for checks and balances throughout the life of the development. A virtual reality system to support software maintenance An evolutionary model seems to be an ideal solution for a virtual reality system, as the development team has two methods first is the exploratory development which works well with customers and to evolve a final system from an initial outline specification. Second is the throw-away prototyping with this method the objective is to understand the system requirements if the requirements are not fully laid out. A university accounting system that replaces an existing system Waterfall has formal structure to manage the process however the drawback is that it is difficult to accommodate changes after starting. But in the waterfall model you would go through a series of step to manage the large requirements, design and implementation requirements. Requirements analysis and definition System and software design Implementation and unit testing Integration and system testing Operation and maintenance An interactive system, running in kiosks in train stations, for railway passengers that find train times In this scenario the best approach would be evolutionary model using a throw away prototyping to find the requirements then switching to a waterfall model for a structured design and implementation.

Marketing demographics Essay

The profile for the potential customers of Bob Bicycles consists of the following geographic, demographic, and behavioral factors: It is said that the immediate geographic target of the company is London. In terms of demographics, the company’s market segment includes male and female whose age ranges from 25 above. In a study conducted, it is noted that commuter cycling in the city is mainly dominated by white males with ages ranging from 25-44; this is because women is facing more barriers in cycling than men (See Figure 2). Most cyclists are also employers and employees who have seen the benefits of cycling with their health, economic and personal factors. As can be seen, children are not considered as a potential market since London is not allowing children to use bicycle for transport. Aside from this, other factors to be considered in the demographics of the potential customers of Bob includes the levels of bicycle usage, reasons for use, behavioral factors and geodemographic factors. Figure 2 Profile of Commute Cyclists 2006-2007 Behavior Factors. In terms of behavioral and cultural aspects, it can be said that Bob bicycles can be considered to have a big potential in London because of the high quality bicycles of Bob which meets the current trends in the bicycle market. In addition, there is a value attributed to the used of bicycle as a means of transport. There are various attitudes to cycling that should be considered by Bob in the London market (See figure 3). This result was based on the study conducted by TFL Omnibus Survey in 2007. Most of the perception of the individuals with regards to cycling is its economic, personal and health benefits. Figure 3 Attitude towards Cycling. Based on the analysis, it can be said that Bob’s plan of expanding his business in the London market, is very feasible and potential based on the current trends in business environment and the pool of demographics and potential target markets.

The Marginalization of Aboriginals in the Canadian Justice System

The original people to live in Canada have adapted the name Aboriginals. They were here before the European settlers discovered the continent of North America. When the Europeans arrived in Canada they brought with the many technological advances and customs that the Aboriginals did not know. Although you might think that this would be a very great thing for Aboriginals, it was not very good. The Europeans thought that the aboriginals were very hostile and treated them very badly.The Europeans tried to assimilate the Aboriginal’s culture and force them to become like the Europeanss. The Canadian justice system has marginalized the Aboriginals of Canada for many years. For the first couple hundred years there were many wars between the Europeans and the Aboriginals. But then things started to stabilize and the Aboriginals and the European settlers began to trade amongst one another and become more and more dependent on each other.However, beginning in 1964, immediately followin g the Royal Proclamation, the British began to gain more control over the Aboriginals. They signed numerous treaties with the Aboriginals for them to give up their land in exchange for a sum of money and small reserve lands specifically for the Aboriginal people. However the land the aboriginals were given was very poor and had bad soil which made it hard to farm. The idea of residential schools set out in 1846 and was put into action in the late 1890’s by the Department of Indian Affairs.The whole point of residential schools was deculturalization of aboriginals. However the government didn’t put it so bluntly. They would say that the aboriginals are put in a â€Å"white society† to learn how to become â€Å"better† Canadians. Not only did residential schools commit culture genocide but there was also lots of abuse at the schools. For example, estimates suggest that as many as 60% of the students died (due to illness, beatings, attempts to escape, or sui cide) while in the schools.They would be punished if they did not speak English even though many of the children didn’t know how. The schools were also very poorly funded by the government and the children were usually taught physical labour. Many of these issues have been solved and the government is still doing things today to help mend what they have done to the Aboriginals in the past. However Aboriginals are still very affected at what has been done to them. First Nation communities experience higher rates of violence, domestic abuse, sexual abuse: rape, incest, etc. lack of family and community cohesion, suicide, addictions, alcohol, food, health problem: diabetes, heart disease, obesity, poverty, unemployment, high school dropout (63% do not graduate), despair, hopelessness and more. The Aboriginal community has been marginalized by the Canadian Justice system which has affected them greatly. Hopefully the government will do everything they can to help aboriginal peopl e become healthy members of society and keep their cultures and beliefs.

Nathaniel Hawthorne Literature of Consience Essay

Nathaniel Hawthorne’s works established him as one of the most unique authors of the 19th century. With works such as The Scarlet Letter, Hawthorne not only entertained his audience, he made them look at their own life and compare it to 17th century Puritan New England. He also brought readers to the realization of how harsh and difficult the period of American History was. Hawthorne’s unique style of writing and his ability to probe deep into the human conscience made him one of Early America’s most greatly admired authors. nbsp;nbsp;nbsp;nbsp;nbsp;The Hawthornes had already left their legacy with the town of Salem leaving Nathaniel Hawthorne a long rich history of ancestry in the town. In 1630, William Hawthorne made the Journey†¦show more content†¦nbsp;nbsp;nbsp;nbsp;nbsp;At the age of nine, one of the most significant events in Hawthorne’s life occurred. The typical New England boy, Hawthorne was very physically active and athletic. One fateful day, while Hawthorne was playing ball, he injured his foot. Not only was his foot damaged, but it grew together improperly and created a problem which would ail him for the rest of his life. nbsp;nbsp;nbsp;nbsp;nbsp;After his accident, Hawthorne was confined to his bed because he had lost mobility. During this time, Hawthorne read many books that would became his favorites, and also have an impact on his writing. These books included Pilgrim’s Progress, by Bunyan, and Faerie Queen, by Spenser. He also enjoyed reading Shakespeare. When the condition of his leg improved, he put on small plays for his sister, who also admired Shakespeare. nbsp;nbsp;nbsp;nbsp;nbsp;At this point in his life, Hawthorne became mildly reclusive because he had been accustomed to sitting inside reading all day due to the fact that he could not walk properly. He mostly confined himself to his room where he began writing. Hawthorne â€Å"founded† a hand-printed magazine, The Spectator, which include some of Hawthorne’s early literature. He filled his magazine with some of his personal humor. His most amiable times were spent in his â€Å"Printing Office† working on his magazine. This appears to be the first time Hawthorne became seriously
