Ground vibration from blasting is an undesirable but inevitable side effect of the use of explosives. High intensity of ground vibration can induce extensive structural damage and cause human psychological discomfort. The PPV has been widely accepted as a measure to assess the damage potential of blasting. This project deals with the significance of the dominant frequency content of the blast waves. The frequency range of waves against the power associated gives a bettwr picture of the blast vibration analysis. The input data of the blast event utilized in this project was collected by blasting carried out in a meteliaferrous mines.

Causes of Software Development Disaster

...Major Causes of Software Project Failures Lorin J. May Crosstalk Associate Editor Most software projects can be considered at least partial failures because few projects meet all their cost, schedule, quality, or requirements objectives. Failures are rarely caused by mysterious causes, but these causes are usually discovered post-mortem, or only after it is too late to change direction. This article is based on interviews with software consultants and practitioners who were asked to provide "autopsies" of failed projects with which they have been acquainted. Although not a comprehensive compilation of failure causes, this article outlines several areas that should demand your attention. few years ago marked the rollout of what could have been called a Titanic of military projects, except the original Titanic was ahead of schedule when it sank. Hundreds of millions of dollars over budget and years behind schedule, the first phase of this huge military system was finally "tossed over the wall" and over the top of a network of separate programs used by thousands of practitioners. Although long hampered by quality problems, big hopes were again riding on the system once it passed acceptance testing. The intended users refused to use the system. It lacked features they said were essential to their jobs while requiring steps they considered unnecessary or burdensome. The project eventually died a visible, painful death amid litigation and congressional inquiries. This failed......

The Role of Software Testing in the Development of Quality Software

...The Role of Software Testing in the Development of Quality Software MehwishZulfiqar 13414, MS (CS) Iqra University, Islamabad. Abstract: In software testing organizations, effective knowledge management of the testing process is the key to improve the quality of software testing. Quality must be built into our products and it can never be tested in after the fact. Although QA has an important role in assuring the quality of our products, their work is entirely indirect. Their role is to influence others in the organization. Testing programs are conducted to ensure that the software application meets the specifications and service level expectations of their product. Testing improves product quality. However, there is rarely enough quality control time built into development projects, and there is an endless possibility of testing that could be executed. In this article major issues are discuss that improve the quality of software and also discuss the role of software testing in the delivery of quality software product.Simply we say that process of testing is basic, but knowing what to test for is challenging for a developer. Software testing requires well-analyzed test cases and proper execution in order to find issues in the software. It also requires efficient management of the procedures. 1. Introduction: Software systems are an increasing part of life, from business applications to consumer products. Most people have had an experience with software that did......

Article on Software Development

...managing software development projects, it would be Linus Torvalds, creator of the world's most popular open-source software program: the Linux operating system. For more than 20 years, Torvalds has been directing thousands of developers to improve the open source OS. He and I sat down to talk about effective techniques in running large-scale distributed programming teams – and the things that don’t work, too. LinusPortland-560.gif Torvalds says there are two things that people very commonly get completely wrong, both at an individual developer level and at companies. “The first thing is thinking that you can throw things out there and ask people to help,” when it comes to open-source software development, he says. “That's not how it works. You make it public, and then you assume that you'll have to do all the work, and ask people to come up with suggestions of what you should do, not what they should do. Maybe they'll start helping eventually, but you should start off with the assumption that you're going to be the one maintaining it and ready to do all the work.” Torvalds continues, “If you start off with some ‘kumba-ya feeling’ where you think people from all the world are going to come together to make a better world by working together on your project, you probably won't be going very far.” “The other thing—and it's kind of related—that people seem to get wrong is to think that the code they write is what matters,” says Torvalds.

...Software Deployment Options The first step in any group policy-based software installation is obtaining the installer file for the software you are deploying. It is a requirement that this installation file be in Microsoft Software Installer (MSI) format. "Once you have obtained the appropriate MSI file, you must create a distribution point for the software to be deployed from. Your distribution point needs to be a centralized location, preferably on a server, where a shared folder can be created that all users have read access to. Once you have created this shared folder, you need only to copy the MSI file into it." "Now that we have prepared our installation file we are ready to create the group policy object that will push out the installation. To do this, we will be using the Group Policy Management Console (GPMC), which is a free download from Microsoft. Create a new GPO by opening the GPMC, clicking on 'Group Policy Objects' in the left pane, and right-clicking in the center pane and clicking 'Create New Group Policy Object.' Finally, type a name for this GPO and hit the Enter key. The name of your GPO should be something brief but descriptive, such as a 'Virus Protection Installation.' "Having a fresh clean GPO to work with, we can now proceed to assigning the installation packing to it. You will begin this by right-clicking your newly created GPO and clicking 'Edit.' Under the Computer Configuration heading, expand 'Software Settings.' Right-click......

Software Development Models

...Software Develpoment Models Elizabeth Hicks Strayer University IT 106 Dr. Hines June 3, 2013 Software Development Models A software lifecycle model is a standardized format for planning, organizing, and running a new development project. Hundreds of different kinds of models are known and used. Some of these include waterfall, code and fix, spiral, rapid prototyping, unified process, agile methods extreme programming, and COTS. Many are minor variations on just a small number of basic models. It is important to survey the main types of model and to consider how to choose between them. A lifecycle model is a description of the sequence of activities carried out in an SE project, and the relative order of these activities. . By changing the lifecycle model we can improve and/or trade off development speed, product quality, project visibility, administrative overhead, risk exposure, and customer relations. Here is a quick overview along with some advantages and disadvantages of five different lifecycles. The waterfall model is the classic life cycle model. It is widely known, understood, and used. In some respect the waterfall is the “common sense” approach. It was introduced by Royce in 1970. Advantages include that they are easy to understand and implement, that they are widely used and known, and that it reinforces good habits: define-before-design, and design-before-code. It identifies deliverables and milestones, its document driven, and works well on mature......

Swat Analysis of Software Company

...A SWOT Analysis view of the software development industry Georgios Kormaris Department of Information and Computing Sciences, Utrecht University, Utrecht, The Netherlands gkormari@cs.uu.nl WWW home page: http://www.cs.uu.nl/ Introduction I n the past twenty to thirty years many changes and developments have taken place in the software industry which started off during the 1960s mainly in the United States of America and experienced a revolutionary boom since the 1980s, Steinmueller, (1995). There are many different ways and methods of developing software and planning the strategy of a software development company, as we can derive from many recent research projects. Most of these projects are usually concerned with the way that software is developed and not with the way that the strategy of the company as a whole is planned, Cusumano, MacCormack, Kemerer, & Crandall, (2003). Another important factor is which techniques and methods are used to analyze company’s environment and how the strategy is formulated and implemented. In this paper we analyze a popular method for strategic planning which has been mostly used for product portfolio planning and strategic planning on an abstract level, as stated in a research paper by Houben, Lenie, & Vanhoof, (1999). We will focus our interest in the software industry and base our research on the case study of the Austrian software industry as it is presented by Bernroider, (2002).

Software Development Life Cycle

...Software Development Life Cycle The software development life cycle is the cycle in which software is developed. It is a process that has been improved upon as programming has expanded and become a bigger part of computers and networking. Programming is necessary in order to enable computers to perform in a desired manner, and those computers rely on that programming as instructions in order to function. Since computers rely on their programming to know how to function, the programming needs to be as efficient and flawless as possible, in order to produce ideal results. The software development life cycle is a tool used to help achieve ideal results. The first stage of the software development life cycle is “Analysis”. This stage is comprised of defining what exactly is required of the software being programmed. It is essential to know what the software must do in order for it to be programmed. All of the programming performed on the software falls within the defined specifications of this stage, therefore, this stage is the most critical. If the requirements are incorrect, the program may perform flawlessly, but it will not do exactly what is needed. The next stage in the software development life cycle is “Design”. This stage uses the requirements of the software as stated in the previous stage, and uses those requirements to design the software. This stage includes writing pseudo-code in order to see what your program needs to do, and taking steps to......

Software Threat Analysis and Mitigation

...Software Threat Analysis and Mitigation CMGT 431 Jan 14, 2015 Software Threat Analysis and Mitigation Many different types of software threats exist today. All of these threats can harm your companies’ bottom line. Whether it is directly by stealing funds, proprietary information, data, or indirectly by damaging code, denial of service, reducing company productivity. There are many different products, services, and procedures that can provide differing levels of protection against these threats. Threats and Counter Measures A buffer overflow attempts to disrupt the function of an application by providing more data to the program than it was designed to handle. This overflow can cause the application to shut down, but it can also cause more malicious effects. Overflow attacks can corrupt program variables causing the program to behave in a way it was not designed to, these attacks can also overwrite software instructions (Gregory, 2010). Malicious software is a generalized term encompassing many forms of code with varying degrees of damage done to a host system. Some of the more common forms are viruses, worms, Trojan horses, spam, spyware/adware, and bots. All of these malicious codes attempt to gain access to your system to degrade your ability to perform as normal. Viruses attempt to corrupt your system so it is unusable, but must be activated by the user accessing a program with the virus attached. Worms are similar to viruses but do not require a......

Software Development Life Cycle (Sdlc)

...Software Development Life Cycle (SDLC) is a series of steps, or phases, that provide a model for the development and lifecycle management of an application or piece of software. The process varies with industries and organizations, but the most common such as ISO/IEC 12207 embody what establishes a life cycle for software, and produce a method for the development, acquirement, and structure of software systems. SDLC can be broken down into six steps. First and most important being planning. Engineers in the organization compile requirements from the client and a scope document is created. Next is the implementation process. The code for the software is written by software engineers in accordance with the clients specifications. The third step is the testing process. This is done by using static and dynamic analysis, as well as manual infiltration testing to ensure that the software can be put into beta environment to test for real-world usability. Next step is the documentation. All steps in the production of the software are recorded for future use and any improvements in the development of the software. Step five is the deployment phase. The software is approved for use and is mass-produced and released to the public. The six and finial step is maintaining the software. Maintenance is performed for the improvement of the software due to the fact new requirements or change request can take longer than the actual software development time. There are a few different models...

Software Development System

...What is the Software Development Life Cycle (SDLC)? July 9, 2013 justin in insight The Software Development Life Cycle is a process that ensures good software is built.  Each phase in the life cycle has its own process and deliverables that feed into the next phase.  There are typically 5 phases starting with the analysis and requirements gathering and ending with the implementation.  Let’s look in greater detail at each phase: Requirements Gathering/Analysis This phase is critical to the success of the project.  Expectations (whether of a client or your team) need to be fleshed out in great detail and documented.  This is an iterative process with much communication taking place between stakeholders, end users and the project team.  The following techniques can be used to gather requirements: * Identify and capture stakeholder requirements using customer interviews and surveys. * Build multiple use cases to describe each action that a user will take in the new system. * Prototypes can be built to show the client what the end product will look like.  Tools like Omnigraffle, HotGloo and Balsalmiq are great for this part of the process. In a corporate setting, this means taking a look at your customers, figuring out what they want, and then designing what a successful outcome would look like in a new bit of software. Design  Technical design requirements are prepared in this phase by lead development staff that can include architects and lead developers. ......

Software Requirement Analysis and Specification

...Abstract:-Software requirement analysis is a method to find out the requirements form the user to develop software. Software requirement analysis and specification also include the types of user requirements and the methods by which developer team can elicit the user requirement and develop suitable software for the user. Introduction:- ➢ Requirement analysis: - Requirements analysis, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. In software engineering, such requirements are often called functional specifications. Requirements analysis is an important aspect of project management. Requirements analysis involves frequent communication with system users to determine specific feature expectations, resolution of conflict or ambiguity in requirements as demanded by the various users or groups of users, avoidance of feature creep and documentation of all aspects of the project development process from start to finish. Energy should be directed towards ensuring that the final system or product conforms to client needs rather than attempting to mold user expectations to fit the requirements. Requirements analysis is a team effort that demands a combination of hardware, software and human factors engineering expertise as well as skills in dealing with people. ➢ Software requirement analysis: - The success of any new......
