Study of Literature for related work is the most important step in software development process. Before designing and developing the tool it is necessary to determine the time factor, the economy and company strength. Considering the importance of software reliability in software engineering, its prediction becomes a very fundamental issue. Machine learning and soft computing techniques have been leading the statistical techniques in last two decades as far as their applications to software engineering are concerned. The most recent research work carried out for predicting software reliability was Hybrid intelligent systems for predicting software reliability [1] Mohanty et al. (2013). The author has employed recurring architecture for Genetic Programming and Group Method of Data Handling (GMDH) and also collaborative models involving GP, GMDH as constituents and GP, GMDH, BPNN and Average as arbitrators in predicting software reliability. Another state-of-the-art review [2] Mohanty et al. (2010) validates the affirmation. The techniques that were employed by the authors were machin...
Failure is not an option, this phrase rushes through everyone’s head while trying to complete a task or goal successfully. Failure is thought of a parasitic word that only successful people have not heard of. With the article “Failure is not an Option” I feel it’s very well written and I agree with much of the article when Allison Carr, the author, explains how failure can be used as a learning tool. While she also states how failure is a bad thing, or parasitic as I stated before. I really appreciated how she covered both sides of the debate. However, I think Carr should touch about grit and open mindedness. Which are the two most vital traits to have while trying to learn from your mistakes, in my opinion.
Humans have an incredible capability for thinking and memory. We can remember events from our past, for our future, and of things that have no relative meaning to ourselves. These memories can be traced back to different systems of our brains through a process of encoding, storage, and retrieval. As part of the retrieval process, memories can be remembered with or without their sources. As research has found, our memories are not labeled or tagged with their origin (Johnson, Hashtroudi, & Lindsay 1993). Because of this, our memory has developed a process called source monitoring. This is how we link our memories to the source that they developed from, usually using specific characteristics and general knowledge of the memory. For example, source monitoring includes identifying who told you something, whether or not you saw an event in real life, the time of the event and whether you told something to your friend or only thought about telling it. The source-monitoring framework for the process involved in pinpointing the origin of information by Johnson and colleagues, explains both vertical and distorted memory with a common set of principles. First, a specific memory consists of specific characteristics including spatial, temporal, and perceptual details. Secondly, the memories can differ in characteristics that can be used to find the origin. More extensive source monitoring can involve beliefs about memory and cognition as well as retrieving more information from memory and finding the source of the memory given these beliefs, other specific characteristics or general knowledge (Johnson et al. 1993). Sometimes these beliefs aren't always accurate. Because some people may be influenced by their personal ideologies during retriev...
The project is going I am working is almost in the finish stage it is going into the production phase means getting to the live so that the users can able to use the application. After the developing the total code it will go to the testing phase where the testers will check the code is working properly without any errors actually the testers task is to check the code and submit to the developers if they found any errors or mistakes or else they will send the code to the production phase to deploy in the server to check the application.
Some software systems have a relatively short lifetime (many web-based systems), others have a lifetime of tens of years (large command and control systems). Some systems have to be delivered quickly if they are to be useful. The techniques used to develop short-lifetime, rapid delivery systems (e.g. use of scripting languages, prototyping, etc.) are inappropriate for long-lifetime systems which require techniques that allow for long-term support such as design modelling.
SDLC( Software Development Life Cycle) , is a process used by the software industry to design, develop and test high quality software .The SDLC aim to produce good quality software that meets or exceeds the user’s expectation and reaches completion within time and cost estimates.
Eugene Burdick and Harvey Wheeler’s Fail-Safe explores the complex moral and ethical decisions that arise out of a dangerous situation. Published in 1962 the novel draws heavily on the fear of the Cuban missile crisis. It utilizes the shared fear of an accidental nuclear attack to present a hypothetical situation demanding of a near impossible decision. Fail-Safe remains a novel worthy of study because of the ethical and moral complications of the decision faced by the President. Fail-Safe attempts to offer a decision that has no perfect or easy solution. These decisions require a deep and personal knowledge of morals, in order to have the ability to make the correct decision. When no easy ethically correct solution stands out the decision becomes dependant on knowledge of metaphorical “line that cannot be crossed.” When all possible solutions require compromise on morals, it becomes necessary to know at what point it becomes impossible to compromise any further without losing the soul or meaning of the person. Fail-Safe aptly creates a situation that stresses this compromise onto a grand scale to evaluate the moral compromise more effectively.
A scop is defined by the Oxford English Dictionary as "an Old English poet or minstrel." However, scops were simply so much more than that to the medieval world. They were the only means of entertainment for the people of the time. There was no television or Internet to escape to, and books were not readily available. Most medieval people in the eighth through twelfth centuries could not read or write,so the scops would tell amusing stories or tales of heroic deeds to the music of their harps. The stories would be chanted, giving great honor to those mentioned in the oral recitations, and the scop's song also provided a memory of the culture for those who would come after.
In recent years, many organizations particularly in a high risk industry have experienced significant losses. For this reason, they have been more considered the importance of the concept 'High Reliability Organization' (HROs). Weick and Sutcliffe (2001) as cited in Takagi and Nakanishi (2006), claim that a comprehending of the HRO concept can lead to clearly understand a technical system within an organization. This leads to minimize any failures from unexpected circumstances. To be more precise, it can be said that the HRO principle assists the organization to determine the risk factors that may negatively affect a company performance in an early stage of a project life cycle. Similarly, Laporte and Consolini (1991) as cited in Aase and Tjensvoll (n.d.) state that any high risk organizations who has applied the HROs principles tend to have an outstanding safety records.
1.0 IntroductionIn this report I will be concentrating on the failure of software systems. To understand why software systems fail we need to understand what are software systems. Software systems are a type of information system. This is because a software system is basically a means for hardware to process information. Flynn’s definition of an information system is:"An information system provides procedures to record and make available information, concerning part of an organization, to assist organization-related activities."Humans have been processing information manually for thousands of years, but with the vast increase of demand for knowledge this century has meant that a new method of information processing has been needed. Software systems have provided a new means that is much faster and efficient.
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Insightfully mapping out the technological advancements in software development from its beginnings somewhere in the late 1940’s to the current modern age. There is more than enough compelling evidence that software technology has laid a strong impact on all economic and social aspects of our modern day living. Thus, a systematic approach towards high quality software development is required due to an increasingly quality oriented market and competitive business world.
In order to compute the 95% confidence interval for Functional reach test (mean) or [Pre_FRT], you need to know 2 pieces of information about the Pre_FRT score in this sample. (3)
Software testing is the process of evaluating a software item to identify differences between given input and expected output. It also confirms that the feature and functions of the software going to be working according to the specifications and requirements. It is considered as most important part of software development cycle(SDLC). Testing actually defines the quality of the product. Software testing is a process which should be done during the development process and the system is complete. In other words software testing combines with verification and validation process. In this Section we test our proposed simulation software with different testing method.
What Information is Relevant when Selecting Software Testing Techniques? By: Vegas, Sira; Juristo, Natalia; Basili, Victor. International Journal of Software Engineering & Knowledge Engineering, Dec2002, Vol. 12 Issue 6, p657, 18p; (AN 9199276)
After reading the paper, “Software Engineering Programs Are Not Computer Science Programs”, it becomes apparent that the distinction between Software Engineering and Computer Science is not as clear-cut to outside observers. Society often blends the two subjects together, nothing that both programs are concerned only with computer science and programming language development. One way to understand the differences is to examine the words, primarily “Engineer” and “Scientist” when dealing with these two subjects. As the paper notes, Engineers are by nature, taught to apply both science and mathematics when designing products. Scientists, on the other hand, are solely taught the science and the methods needed to advance it. Overall, Software Engineers
