The Importance Of Software Engineering

The Importance Of Software Engineering The ticket distributor will include a touch screen for displaying instructions and inputting commands. The only other control will be a cancel button for aborting a transaction. The ticket distributor should be at most one and half meters tall so that the traveler can easily operate the ticket distributor i.e. the traveler can easily insert the request for the desired ticket and the money. If it is very tall it will be difficult to operate. So that the ticket distributor is available to the traveler at least 95% of the time. If one computer crashes the other twin can take over. Other than this two computer systems might also be used for dividing the tasks. One could manage the money transactions while the other one could take care of the GUI and providing the travelling options and the amount etc. This is because a touch screen system is more interactive and it also occupies less space. Plus all the functionality can be easily implemented using the touch screen so there is no requirement of a keypad or any such device. Question: Specify which of the following decisions were made during requirements or system design: à ¢Ã¢â€š ¬Ã‚ ¢ The ticket distributor is composed of a user interface subsystem, a subsystem for computing tariff, and a network subsystem managing communication with the central computer. à ¢Ã¢â€š ¬Ã‚ ¢ The ticket distributor will use PowerPC processor chips. à ¢Ã¢â€š ¬Ã‚ ¢ The ticket distributor provides the traveler with an on-line help. Answer: This decision should be made during the system design process. This decision should also be made during the system design process. This decision is part of the requirements gathering process. Question: A passenger aircraft is composed of several millions of individual parts and requires thousands of persons to assemble. A four-lane highway bridge is another example of complexity. The first version of Word for Windows, a word processor released by Microsoft in November 1989, required 55 person-years, resulted into 249,000 lines of source code, and was delivered 4 years late. Aircraft and highway bridges are usually delivered on time and below budget, whereas software is often not. Discuss what are, in your opinion, the differences between developing an aircraft, a bridge, and a word processor, which would cause this situation. Answer: An aircraft or a bridge no matter how complex, are examples of physically tangible products. Software on the other hand is not physically tangible. Any such thing requires excessive brainstorming and thinking. In case of the above mentioned examples the end product that is an aircraft or a bridge is known while in case of software the customer and the creator are never too sure of the complete end product. During the course of development of software the requirements of the user might change. The user might want to increase or decrease the functionality. Other than this the creator has to think of all the aspects and scenarios in which the software will be used, which is not possible. All the possibilities can never be taken into account; the developer can only come up with the most effective solution. And that solution might not be valid after sometime. SECTION B Question: Why Software Engineering is important? What is the role of SE in Telecom and System engineering? Answer: Software engineering (SE) is the profession, practiced by software engineers, concerned with specifying, designing, developing and maintaining software applications by applying technologies and practices from computer science, project management, and other fields. SE technologies and practices improve the productivity of developers and the quality of the applications they create. Software engineering plays a major role being the backbone of software systems by applying technologies and practices not only technically from computer science and engineering, but also with management issues such as project management, plus the telecom and other fields. [Reference: wiki.answers.com, google.com] Software engineering is the discipline of designing, writing, testing, implementing and maintaining software. It forms the basis of operational design and development of virtually all computer systems. The discipline extends to application software on personal computers, connectivity between computers, operating systems and includes software for micro-controllers, small computers embedded in all types of electronic equipment. Without software engineering, computers would have no functionality. Although hardware is just as important, no software means no computers. It is a fundamental part of todays information systems and engineering and our lives would be very different without it. [Reference: essays.se, google.com] Importance in Telecom Industry: In the telecom industry mere hardware is never enough for the process of communication to take place. It works at its best when the hardware is used to its fullest by using software along with it. In the telecom industry, software engineering is used right from the core of the communication network to the top most level. SE in telecom is used in the following three categories: Mobile applications and services implementation and development. Custom application development specifically for telecom operators. Custom embedded linux platform development for the functioning of servers, switching towers etc. Importance in Systems Engineering: Systems engineering include all sorts, shapes and sizes of communications systems, embedded systems, DSPs etc. SE is important not only for these systems to work but also for their design and development phases. SE is used for their functionality, maintenance, testing and execution. SE in systems engineering include the development and usage of the following products: Firmware BSP Device drivers Protocol stacks etc. It also includes the application of leading embedded hardware and software platforms such as VxWorks, Embedded Linux, pSOS, OSE, Win CE, XP Embedded, and diverse processors such as Intel, PPC, ARM, Freescale MPC and network processors.

Legalizing Marjuana Essay

The legalization of marijuana in the United States has been a major issue for several years. There are many opinions on this topic, some people don’t give marijuana a thought. Many people including most government consider marijuana a â€Å"bad drug†. Marijuana actually has many good uses. Marijuana should be legalized for medical purposes, to reduce America’s prison population and to boost the economy. The use of marijuana as a medicine is rapidly becoming popular in the treatment of various types of illnesses. Sixty-five percent of Americans were for legalizing marijuana for medical purposes (Update: Medical Marijuana). Every year there are different trials being done that prove marijuana has good medicinal use. Medical marijuana can be used in providing pain relief for people with different cancers and HIV/AIDS (Update: Medical Marijuana). It has been used to provide relief for nerve pain in patients with AIDS (Update: Medical Marijuana). Marijuana is also eff ective in treating nausea in cancer patients that go through chemotherapy. Some States have already legalized medicinal marijuana, while others are more reserved. Georgia just legalized the use of marijuana oils to be used for medicinal purposes. Additionally, people being arrested for marijuana is causing over population in the prison systems. Some people that support the legalization of marijuana think that law enforcement fighting the war against drugs should focus their attention towards other violent crimes or hard-core street drugs. Marijuana is the most widely used and prosecuted drug in the United States (Decriminalizing Marijuana). Ninety percent of the people arrested in 2007 were arrested for simple possession alone (Decriminalizing Marijuana). People that are being arrested for marijuana are being sent to jail/prison with violent criminals. Law enforcement could use a different way of dealing with people that are being arrested for marijuana like righting a ticket, inste ad of spending taxpayer’s dollars on sending them to prison. The over population in our prison system is a heavy burden on taxpayers. Furthermore, legalizing marijuana would be a major boost for the struggling economy. More people are in agreement with legalizing marijuana when the issue focuses on using it as a taxable substance (Decriminalizing Marijuana). There is such a demand for marijuana already that legalizing it could only boost the economy instead of hurting it. Unemployment has been a major issue in America today. Legalizing marijuana would generate jobs for thousands of people in various different fields of work. In addition, the tax revenue would benefit students of all ages by providing grants and scholarships for education. It has been estimated that legalizing marijuana would generate $10-$14 billion dollars in savings and tax revenue annually (Decriminalizing Marijuana). Instead of the government spending money on restricting the use of marijuana, they could make money off legalizing it. The government could tax marijuana just as they tax tobacco and alcohol. In conclusion, the times are changing, more states are agreeing to legalize marijuana, both for medicinal purposes and recreational use. Mar ijuana should not be treated any different from the way people treat alcohol and tobacco. Legalizing marijuana would benefit Americans for medicinal use, it would also decrease over crowding in our prison populations and help our struggling economy. It is time for our government leaders to become more open minded when it comes to the topic of marijuana. Works Cited Update: Medical Marijuana.† Issues & Controversies On File: n. pag.

Jim Poss Case Study Analysis

The main growth strategy that Jim counted on really was based over the potential upcoming increase in demands for clean and cost cutting energy solutions. The newspaper reminded him that as energy prices will soar. Logistics for cost saving could be the origin of birth of a new and ever growing sector, and and that if he got on it early on (as he did), This could prove to be a lucrative idea. BigBelly wasn't only a device for saving Money. t could've been marketed for the green-image portrayed by its presence in public spaces and how this could help improve the eco-friendly image of the companies that uses them. in the early 2000's large corporation were already massively funding various Corporate social Responsibility[CSR] projects, mainly for their public image and thus profit, this would've been an ideal marketing niche as Devices such as Jim's serves those exact needs, Yes I would have taken the order.Jim's decision to accept the order from the Ski resort was a smart one, risky b ut smart, this was a truly exceptional and perhaps irreplaceable opportunity,lets put it that way: the fact that a business(in trouble) was willing to invest in a device (electric or not) without even being able to test it beforehand is an accomplishment on its own, but the fact that its developer wasn't even sure how to actually build it, was an even greater one, sure Jim had constructed and sold a prototype before, but as long as Vail is concerned the devices they're Purchasing (3 at first) didn't even exist yet.Finally I believe that if it wasn't for the deadline and by being under time constrain, Jim and his team would have taken much longer to figure out the ins-&-outs of the manufacturing process of BigBelly, and thus perhaps lose future opportunities

Environmental impact of tourism in Romania Essays

Environmental impact of tourism in Romania Essays Environmental impact of tourism in Romania Essay Environmental impact of tourism in Romania Essay The Environmental Impact of Tourism in Romania Introduction In this essay the chief attending will be focussed on the impact of touristry upon the environment in Romania, so the positive and the negative facets of touristry will be brought in treatment. In Romania the environment is a factor act uponing touristry demand. Given that the demand for merchandises of involvement is partially determined by its quality, the environment can hold a positive or negative impact on touristry. Tourism-environment relationship is peculiarly of import, protection and preservation of the environment being the primary status for advancement and development of touristry. This nexus is complex ; it is manifested in both waies. The environment is defined as the quality of life of people populating and natural environments suited home grounds for animate beings and workss. The impact of touristry on the environment The positive impact Tourism is one of the most of import industries and has developed continuously. Romania is visited by more people which are interested in researching new finishs and civilizations as distant. Therefore, countries holding particular natural resources pull more visitants, particularly if they offer the chance to cognize the imposts and traditions of other civilizations. When touristry and environment coexist in harmoniousness, environment benefits from touristry. There are many illustrations of this sort, most falling into one of two types: preservation and environmental rehabilitation. Preservation means maintaining informed pick and usage of the natural and anthropogenetic. Conservation and touristry frequently go manus in manus. In Romania many historical and archeological memorials have been saved from devastation because of tourer involvement to them. In Romania Parkss and nature militias managed to protect many species that would otherwise hold been destroyed by uncontrolled hunting. Tourism non merely provides a ground to continue the environment from adult male, but besides provides money for preservation: a portion of the income from touristry can be used to continue the environment. In this tourer from all over the universe are involved in different touristic plans like boosting the trails of medium and high trouble, sing historical memorials and paleontology, easy paths to points of Belvedere, and Keys resort to R A ; acirc ; usor Buti, trails for ski touring, mounting paths, plans for the survey / observation of vegetations, bird observation and observation hints animate beings. Conservation implies saving of the environment in a signifier as stopping point to the original, rehabilitation involves a major alteration in the usage environment. Many edifices and tourer countries have been saved by being restored as tourer attractive forces or tourer adjustment. Many edifices and tourer countries have been saved by being restored as tourer attractive forces or tourer adjustment. Many mills in Romania began a new life as museums, industrial countries were converted into topographic points of festivals, a assortment of impressive palaces and houses that were in decay became adjustment for tourers. Such illustrations show how the environment can profit from touristry, salvaging what would otherwise be lost wholly. The most of import natural modesty from Romania, natural memorial, internationally recognized as a Biosphere Reserve is Retezat National Park. The park contains many touristic attractive forces such as over 80 lakes, 20 extremums over 2000m, the most extended and deepest glacial lake in Romania, more than 54 home grounds of rare or vulnerable workss and animate beings, glacial alleviation in the North and acerb terrain in the South. In this reserve tourer from all over the universe are involved in different touristic plans like boosting the trails of medium and high trouble, sing historical and palaeontological memorials, visible radiation trails to points of Belvedere, ski at R A ; acirc ; usor and Cheile Butii, mounting paths, plans for the survey and observation of vegetations, bird observation and observation animate being trails. Another international known touristic attractive force from Romania is the Danube delta. Tourists from all over the universe choose the Danube delta as their holyday finish because of its alone landscapes and home grounds. This has a good impact upon the natural reserve, because foreign tourers help raising the money for modernizing and keeping the many and diverse natural home grounds in the delta. The negative impact Tourism is a consumer of infinite and tourer resources, take parting default debasement and environmental pollution and touristry potency. This debasement is carried out either by direct force per unit area of tourers on the landscape, vegetations and zoologies and other tourer attractive forces on which touristry can partly or wholly damaged or recovery by the misconception of some countries, points and tourer attractive forces. Human force per unit area on the natural environment additions twenty-four hours by twenty-four hours, people traveling more frequently and longer distances on the yesteryear. Leisure offers greater chance in the development and conquering of the natural environment, most free clip is spent outside the metropolis, in nature. Periodic end product of the metropolis to green countries in the signifier of Tourss, a weekend or vacation sites has become a societal usage with negative environmental effects. Many of the environmental harm caused by touristry are c aused by the big figure of visitants geting at finishs whose optimum response capacity has been exceeded. Environment seldom escape injury when the figure of tourers is really high. Air and H2O quality and diverseness of vegetations and zoologies are necessarily affected in some manner, and landscapes, metropoliss and memorials. Motion of uncontrolled tourer sightseeing done in natural or anthropogenetic causes of frequently irreversible devastation of some of the points they have devoted to tourist attractive forces ( the devastation of flora and vegetation, interrupting trees and particularly juveniles, poaching, debasement of the landscape ) . Pollution is increasing and because of the nature of car touristry whose hurtful consequence is change of air quality, devastation of grasslands, trees and vegetations, etc Another manner of environmental debasement is the intent of investing unscientific and irrational nature touristry, investings take the signifier of: over-dimensioning Stationss in footings of response and intervention capacity, failure of general rules of natural resource de velopment. An illustration demoing the common relationship between touristry and environmental composite in general, and the negative impact that it manifests on each other, in peculiar, is the disappearing of the last 20 old ages to 14 huts in the Rumanian Carpathians, the loss due to fire. Such harm is due to carelessness of tourers. Decisions Through this essay it has been showen that touristry has much more negative impacts on the environment of Romania than positive 1s and that they are frequently closely related to the economical facet of touristry. In decision Romania is a state basking a natural scene with great possible and substructure frequently plenty natural touristry, travel signifier, in this position, is less demanding . After research, consequences that Romania does non profit by much more positive facets, since many constituents of the environment have been destroyed by tourers, instead than preserved. As Romania has much to make about environmental saving. After research, consequences that Romania does non profit by much more positive facets, since many constituents of the environment have been destroyed by tourers, instead than preserved.

Laborers of the 1920s essays

Laborers of the 1920's essays Laborers in the 1920's had it made. New technology and machinery produced products twice as fast and rolled in the big bucks for companies. This new technology and machinery made working life for them easier and less stressfull. There was less to do, yet they produced a lot more while doing less. In buisnesses like Ford Motor Company the new technology, which in this case was the assembly line, helped Henry Ford produce thousands of Model T's a month for the wanting public. The workers in the Ford production plants got more leisure time due to the decrease in work hours in the factories, which was made possible by the major decrease in production time. Before the inventions of the new technology and machinery in factories, workers had to put everything together by themselves using nothing but their hands. After the inventions of the new technology and machinery workers had to do less with their hands because the machines helped them out. The assembly line pushed the cars along while passing through different stations one after another. Each station had a specific task that was to be done there. Instead of of the workers hauling the car around on dollies while it was being put together the assembly line carried it along, this decreased the production time dramatically, Which helped workers get paid more because the buisness was making more. New technology brought new consistant ways of working. This for the most part, eliminated human error and brought in new, more efficient. These new products could now be mass produced because of the new machinery and inventions. The mass production helped workers produce more products which again brought in the big bucks for the company and the workers. Laborers of the 1920's also had another part of their life, their leisure time. The inventions of new products some of which they produced themselves, brought more fun and less work to their normal lives. The automobile brought a sense of ad...

Avatar movie Review Example | Topics and Well Written Essays - 750 words

Avatar - Movie Review Example Anthropology is the scientific research of human beings and their ancestors. â€Å"When his twin brother is killed, disabled ex-Marine Jake Sully is recruited to aid a mining expedition on the distant jungle moon of Pandora as only his DNA will bond with the alien hybrid body, known as an Avatar, which allows humans to breathe the toxic air.The initial impression one gets about the Na’vi aside from their alien trappings, is that they are a primitive race. Primitive is a relativistic term and here it is used to mean that they are technologically backwards compared to the humans who come to Pandora. The Na’vi subsequently faced with the challenge that comes when a tribal community comes into contact with a more technologically advanced civilization. The humans who come to Pandora are there to mine the local minerals to be used back on their home planet. This begs the question, ‘what happened to their home planet?† The Na’vi cultural practices resemble those of other pre technology civilizations. They live in small villages spread throughout the planet. They have developed a form of religion, a system of government and have learned hunting as a source of sustenance. They also have their own language used for communicating with one another, and with the local wildlife using their body language combined with high pitched shouts and clicks.The language is more intuitive more than descriptive. For example when they say â€Å"I see you,† it mostly means that they see into you rather than a visual interpretation of the observed object or individual. Their language is also accompanied with hand signals and movements to emphasize emotions and ideas communicated (Chris, 2012). As history has attested time and time again, when a more technologically advanced civilization comes into contact with what they perceive to be a primitive society, the humans take it upon themselves to â€Å"civilize† the Na’vi. Motive aside, th e impression that what the humans have in terms of technological advancements is I think misguided. The Na’vi are not the one who have bled their home planet dry, and have then travelled halfway across the galaxy in search of the aptly named mineral unobtainium. In the aim of civilizing the natives, the human open school, teach the Na’vi their language, they also try to trade their medicine and food with the Na’vi with the aim of obtaining the unobtainium (Chris, 2012). The Na’vi on the other hand feel that the humans are misguided, and also unsuccessfully try to teach them their way of life until the arrival of Jake Sully. There is a mutual sense of ethnocentrism within the two communities, and whether it is justified is a matter of opinion. The humans feel that their way of life is superior to the Na’vi while the Na’vi feel that their way of life is the only way to live harmoniously with their environment. The Na’vi live in the jung les of Pandora, their main food source is the jungle. They are hunters and gatherers. They also domesticate the local wildlife and use it as a means of transport. They also use the animals to hunt and defend themselves. As with most hunter gatherer communities, prowess in hunting is highly valued and strength greatly affects the individual’s status within the community. They have a sense of brotherhood and oneness with their prey since it is part of them, part of the jungle and thus part of Eywa. They do not needlessly kill their prey and only hunt what they eat. They even go out of their way to reduce instances of confrontation between themselves and the hostile wildlife in the jungle. This

Organization, people and performance Essay Example | Topics and Well Written Essays - 1750 words

Organization, people and performance - Essay Example The rest of 24% employees are actively disengaged. Thus, employee engagement is very low in most companies worldwide according to the research. For instance, in places like China where staff turnover mostly happens in epidemic proportions, knowing how to build loyalty and engage employees is crucial to the success of Tesco. In light of this, employee engagement is significant to Tesco mainly because it improves employee satisfaction, productivity, retention and recruitment, innovation, and company profitability. First, employee engagement leads to employee satisfaction. According to Beardwell, I., Holden, L., & Claydon, T. (2001), employee’s job satisfaction tends to increase considerably if they are engaged by the company. Subsequently, satisfied employees develop a positive attitude towards the success and performance of the company. Tesco would gain by having satisfied employees since they are committed to the success of the firm. Additionally, their loyalty increases. On a broader perspective, satisfied employees act as ambassadors of the firm. Thus, they support and promote the firm’s brand, mission and strategy. Next, Tesco’s productivity would increase as a result of employee engagement. Robinson, D., Perryman, S., & Hayday, S. (2004) implied that since engaged employees go the extra mile, they lead to increased productivity. Thus, for employees to be top performers, they have to be engaged with the company. As they become more engaged, employee absenteeism reduces while motivation levels tend to increase resulting in increased productivity. In simple terms, the more a firm’s employee is engaged, the more efficient the employee becomes. Lockwood, N. (2007) argued that firms with engaged employees often have their productivity levels increase by more than 43%. Moreover, employee engagement will lead to a low employee
