The Architecture Of Software Intensive Systems - 1449 Words

Article 1 summary This article is mainly describing about the architecture of software intensive systems by using multiples of concurrent views, which is allows to study about the various stakeholders , end users,developers,system engineering, project managers,etc.., and to handle indusully functional and non function requirements. Mainly software architecture deals with the design and implementation of high level structure in software.It is the result of combination of many architectural elements in some well chose from to satisfy the functionality requirements and non functional requirements like reliability,scalability,portability,and avalibility. It is very difficult to represent the architecture in the set of boxes and arrows which shown on these diagrams.So as the remedy,author has proposed the description of a software architecture using several concurrent views,each one address one particular set of concerns. A View model is in system engineering or software engineering is a framework which defines coherent set of views to be used in construction of software architecture Philippine kruchten designed the 4+1 view model which describes the architecture of software-intensive systems using multiple ,concurrent views.The four view model are logical,development,process and physical.In addition to this selected scenarios are used to describes the serving as plus one view.use case view has a special significance, it effectively redundant ,deals with highShow MoreRelatedImplementing A Flexible Open Architecture Based Radio System933 Words   |  4 PagesSoftware defined radio (SDR) aims to overcome the limitation of the conventional radio by building a flexible open architecture based radio system.

Skin Sensitivity Free Essays

Block 5 Skin Sensitivity Lab Hypothesis: The fingertips will be the most sensitive because they are used the most for touching things all of the time. The area that will be the least sensitive is the shins because we are constantly bumping into things with our shins so they need to be less sensitive to pain.

The least sensitive areas of my body were my forearm and forehead. This partly supported my hypothesis because the fingertips were among the most sensitive but my shins were not the least sensitive. My results were fairly close to the rest of the class. The only two areas that were more than a point apart between my data and the class average were my palms and my nose. These areas were more sensitive to me than the rest of the class. Some areas might be more sensitive because they are involved with touching and bumping into things than others. For example my fingertips were far more sensitive than y forearms because I use them to touch things all the time and the touch receptors are more dense in them. It makes sense that touch receptors are more dense in areas that are involved in more touching than others. In places where a lot of bumping into things occurs such as the shins, touch receptors would be less dense because you wouldn’t want to feel all that pain all the time. Meissner’s corpuscles are light touch receptors in the skin wh ich are prone to touch sensitivity. They are located just under the epidermis, which makes sense because they are closer to the outside so they can be more sensitive to light touch. Pacinian corpuscles are touch receptors located deeper in the dermis in the skin that respond to touch and pressure. They are good for feeling rough surfaces and determining vibration. The location of these receptors are deeper in the skin because they are designed to feel pressure so when something pushes down on the skin they can respond. The homunculus diagram is showing how the human body would be built if it was in proportion to the amount of sensory and motor brain power needed to control each part. The hands and mouth are bigger because they require more brain power to control. In the somatosensory cortex diagram the mouth and hands are also bigger which might explain why the skin in both of these areas is more sensitive than in other parts of the body. In both diagrams the bigger body parts require more control from the brain and have more sensitive skin. How to cite Skin Sensitivity, Essay examples

Effective Study Skills Are the Sole Foundation of a Sound Education free essay sample

To establish whether or not effective study skills are indeed the core foundation of a sound education, there firstly needs to be an understanding of what study skills are and what is meant by a sound education. Other factors that impact on education also need to be explored. The term study skills is defined in Wikipedia (2012) as â€Å"techniques to assist the individual to be an effective learner. † Although some students may naturally possess good study skills, most people do not. However Cottrell (2008) explains â€Å"a skill is a learned activity, something that can be developed through practice. † Time management, active listening, reading comprehension, presentation skills, memory techniques, critical thinking skills, research and evaluation, writing skills are all categorised as study skills and whether a natural attribute or an acquired skill have to be fine tuned and developed in order to be effective. A review by Biggs Purdie (1996) found that study skills can be taught and that they can add between one and two grades to a students results. We will write a custom essay sample on Effective Study Skills Are the Sole Foundation of a Sound Education or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page However as education is defined in the Collins English Dictionary (2006) as â€Å"the imparting and acquiring of knowledge through teaching and learning† there are many other factors beside study skills that impact on an individuals education. Social, economic and cultural backgrounds can have a massive influence over the ability for young people to access even the most basic education. In many parts of the world, free public education is still not readily available for all children and as reported by the BBC (2006) a study carried out by the Nations Education Organisation Unesco finds sending one child to primary school can cost more than a month’s wages in many third world countries. Having access to free education however does not necessarily guarantee success. Children of lower socioeconomic groups who have access to free education can face many barriers in education, with attitude, aspiration and ehaviour toward education playing a part; proving â€Å"life opportunities can make a significant difference on natural intelligence (Stella 2008) Parenting skills can also impact on a childs’ education, for instance, a child’s reading ability is associated with the reading environment around them and there is evidence (Joseph Rowntree Foundation March 2010) that parental involvement with school is associated with achievement. Previous negative experience can also be a barrier to learning for students from all walks of life. A bad learning experience in the past can have a lasting impression on a students’ attitude towards education. This leads on to the final ingredient lack of motivation. The student has to have a willingness to learn and no amount of techniques and skills can improve a persons desire to want to learn. In conclusion, although popular opinion agrees effective study skills are a necessary and valid tool in the building of a student’s education, unless all the other pieces in the jigsaw are in place study skills are either irrelevant or ineffective and therefore cannot be deemed to be the core foundation of a sound education.

Politics Of Displacement Essays - Guggenheim Fellows,

Politics Of Displacement Jean Elshtain, Chp.2 Democracy and the Politics of Displacement Response to Question 1: In the excerpted chapter titled Democracy and the Politics of Displacement, Jean Elshtain discusses the concept of ?politics of identity'. In discussing the ?politics of identity', Elshtain argues there is an emerging social phenomenon, wherein society is turning the private affairs of our lives into public discourse. The Western World has become a public pool, in which the information mediums and venues of society are overflowing with confessions and apologies. We have made the private affairs of our lives, into a booming business. Society has witnessed a proliferation of self - help groups, ?twelve- step' programs, anger management programs, television shows broadcasting a ?tell all' theme and Internet chat groups designed for people to post the confession and/or apology of the day. Inherently, it has not only become socially acceptable, but socially encouraged to air our dirty laundry. We are actively creating an ?Apologizing Society.' Elshtain argues that as the boundary separating the private and the public becomes increasingly hazed, a new social identity emerges. Elshtain argues that as this new social identity emerges, there arises a ?politics of identity.'Our social identity is no longer composed of differentiated spheres of human activity, but rather it has become a dichotomous social relationship involving those who are victims and those who are victimizers. Moreover, it is the quality or character of being a ?victim' that becomes public discourse. In turn, this quality of being a victim becomes an individual's primary or dominant identity: it defines their entire being. Through the process of class discussion, it was realized, that as the quality of being a victim enters the public lime- light, there emerges a social accumulation of victims and victimizers. The social accumulation of victims emerges as a result of two factors: 1) as the quality of being a victim becomes more public, it's definition and defining characteristics begin to broaden. Thereby, accumulating and embracing a variety of ?victims,'that otherwise, may never have come to view themselves as having been victimized; 2) as the definition of being a victim becomes more broad in the public sphere, it simultaneously becomes glorified and popularized. That is to say, society begins to credit a great deal of sympathy to, and focus a lot of attention on, those who have been victimized. As a result, a social phenomenon emerges, wherein everyone wants to be a ?victim.'As a final note, the social accumulation of victims continues, as some victims feel compelled to engage in the public service of sharing their experience with the world. For example, we often hear victims injecting society with notions of victimization through injunctions such as, My experience will have served a purpose, if I can help one person to understand that they are not alone. Essentially, there is a collective engagement among victims, to ?accumulate' more victims. Response to Question #2: Elshtain argues that the ?politics of displacement' are essentially bound up in the politics of identity, as the private self become increasingly more public, and therefore, the public begins to ?displace' the private self within society. Moreover, Elshtain argues that the politics of displacement are circumvented by two paradoxical connections, wherein: 1) everything private becomes public and 2) everything public becomes private. Through the course of class discussion, it was realized, that although Elshtain argues that everything public become private, she does not mean this, in its literal sense. Elshtain, merely presents the paradox to create the necessary juxtaposition, in which her politics of displacement can be clearly articulated. For Elshtain, the politics of displacement remain emphatic of the increasing disappearance of the boundary separating the private from the public spheres of social life. Elshtain further argues, that the politics of displacement are increasingly cutting away the social space necessary for society to maintain conventional politics. Elshtain concedes, that conventional politics have now become bound up in the politics of displacement and inherently, the politics of identity. Hence, this new social identity of being a ?victim,'which was discussed in the above response, has increasingly billowed over into conventional politics. For example, conventional or traditional politics did not encourage politicians to disclose information and details about their personal life, in contemporary society, ?telling all'

buy custom Critical Thinking - Portfolio essay Critical thinking plays a vital role in an individuals learning process. This is an active process that involves examining different situations without bias, evaluating consequences of a decision, and eventually making a rational conclusion (Ellis, 1997). Before one agrees with an idea, questions ought to be asked about it, a thorough analysis be done and possibilities be exposed. In critical thinking, everything is taken as an assumption. In effect, critical thinkers believe that applying a critical thinking analysis is able to help in coming up with the comprehensive truth of situations. Critical thinking also seeks to find out differences between truths and fallacies. Critical thinkers try to be resourceful by using creative options that will help in coming up with the most effective option. The application of creativity in critical thinking is essential in keeping flawed human thinking in check. Ellis (1997) writes that brainstorming is one of the techniques that help in critically analyzing a situation before making a conclusive decision. It helps in coming up with as many solutions as possible for that situation. Some of the solutions may at first look foolish, but analyzing them leads to making a sober choice. It is important to look into all the solutions written down and question them. Critical thinkers have distinct qualities that make them stand out. These qualities help them in their main mission of finding the truth in a given situation. In this case, the first quality is acceptance. This makes them always accept all other opinions that may sometimes be against their thinking. To find the truth, they are all the time guided by the evidence. Another important quality that distinguishes a critical thinker from a non-critical thinker is the open-mindedness. A thinker values the diversified opinions of different individuals. They therefore see to it that they do not give opinions that appear biased. Due to this, they are able to make better choices than non-critical thinkers who only rely on their own opinions. The final quality is analytical ability. This helps a critical thinker in formulating a possible outcome that may arise when an opinion is adopted. This comes from the hunger for more information. With these qualities, a critical thinker is able to apply thi s technique to find the most effective option. To acquire the above qualities, a person should be willing to admit lack of knowledge in a given situation. This allows one to get more opinions and ideas that add into the knowledge. Being quick to criticize is also not a positive path towards being a critical thinker especially when the critics are negative. Thhis is only possible if one recognizes the differences that exist in every individual. In fact, no one is the same as the other. Questioning is also an important aspect of being a critical thinker. This is the real art of thinking critically. It widens the understanding of an individual to be able to make rational choices. Finally, it should be noted that learning entails acquiring knowledge of new things. Critical thinking is very essential to this process because it opens ones scope of understanding. Learning and critical thinking processes both require finding new ideas, analyzing them and eventually drawing comprehensive conclusions out of them. It should also be noted that in learning, observations are made, questions are asked, and evidence is unraveled to come up with concrete points. Critical thinking helps in opening the mind to this fact. It therefore greatly contributes to the learning process (Ellis, 1997). Thinking critically helps to build relativism in learners. The learner is able to develop the analysis out of the opinions from the others. By doing this, reasoning plays a major role in coming up with conclusions rather than engagements in negative criticism (Kurfiss, 1988). This means that when people are reasoning they are not offering negative options, instead they are searching for options that will build the conclusion.

Boivail case

First, Persuasive evidence of an arrangement exists. We can see that there must be an arrangement between Avail and distributor. Second, the sellers price to the buyer is fixed or determinable.Third, collegiality is reasonably assured. Fourth, Delivery has occurred or services have been rendered. From here, we could recognize revenue of the company according to FOB. FOB shipping point, title to the property rangers to the buyer when it leaves the shipping dock and therefore revenue should be recognized at that point. With FOB destination, title does not transfer to the buyer until they receive the goods and thus revenue is not recognized until that point 3. How does the accident affect the stated revenues under different FOB contract structures? Explain your reasoning? If Avail recognizes revenues when the product leaves Violas FOB shipping point then revenue should be recognized at that point. Therefore, the truck accident would have had no impact on Violas third quarter uncial results because the title to the product and the risk associated with the accident would have passed to the Distributor as soon as the truck left Violas. Then, overstating revenues and net income on financial statement should not have happened. However, Distributor mentioned that they recognized the distribution as FOB destination then revenue will only be received by Avail until goods arrived at the point, so if Avail recognizes revenue when the product has reached the Distributors FOB destination it has recognized revenue when it has been earned and ill accurately state revenues and net income on its financial statements. 4.Are you concerned about the companys treatment of analysts who cover the stock? Would you want to be an analyst covering this company? Yes, I am concerned especially about the downgraded stock recommendation that was given to Avail. However, I would not be an analyst covering the company because there were too many misleading information in the company that would cause me as analyst to formulate wrong decision. Moreover, it might also ruin my reputation as analyst if I formulated wrong decision.

Emirates Airlines Essay Example | Topics and Well Written Essays - 2000 words

Emirates Airlines - Essay Example Emirates is one of the fastest growing airlines in the world and it has consistently posted an average of 20% growth in annual profit since 1985 (Plunkett, 2007). This research studies some key components of Emirates Airlines and how it relates to tourism and management. It examines the operational characteristics of the airline and how it aims at expanding its scope. The second section of the paper examines the financial performance of the airline and its implications. Finally, the paper examines the competitive situation of the airline and concludes on the findings. From the webpage of Emirates Airlines (Emirates Story, 2012), it started operating in October 1985. It aimed at providing high quality flight services to and from Dubai. The airline is mainly owned by the government of Dubai but it operates as an independent entity. Emirates has over 160 aircrafts and flies to over 100 destinations in 66 countries. A total of 40% of the flights are to or from Dubai. The growth in traffic for Emirates Airlines is characterized by the cumulative expansion of the airlines fleet. In 2001, there were just about 9 million passengers who flew on Emirates but by 2006, it had increased to 17.5 million (Graham et al, 2010). This is done through the offer of different classes of services that ensures that different people from different backgrounds are serviced by the airliner. Emirates flies to 111 cities and operates in five different global regions around the world (Emirates Routes, 2012). In each of these regions, Emirates Airlines provides various services that aim at meeting certain targets that are unique to the continent. In Africa, Emirates flies to 21 cities on the continent. Emirates flights to Africa was hinged on the expansion of business activities with Dubai. Since Dubai was set to become an international destination that links the developing world to Europe and North America. Due to the
