The main aim of software industry is to provide high quality software to users. For this, it is essential to test software. Software testing involves a no of issues like test case generation, prioritization of test cases etc. The paper reviews various test case prioritization techniques. Test case prioritization techniques help to organize the test cases. This will help to reduce overall effort...

Software development and evaluation is the most difficult task in software engineering. The future of the software industry depends upon the development of software. For this purpose quality is considered essential step in designing software. Quality of software is dependable upon different aspects but the dream of software quality is not feasible without software reliability. Reliability of so...

A fundamental axiom of computer system design holds that "any software design problem can be solved by adding an extra level of indirection." This paper expresses a variant of this axiom in pattern form as the "Identity Indirection" pattern. This pattern has been used for decades in many different types of systems in the software industry. It is so common that many developers hardly notice it a...

This work aims to improve the oxidative stability of alkaline amylase from Alkalimonas amylolytica through structure-based site-directed mutagenesis. Based on an analysis of the tertiary structure, five methionines (Met 145, Met 214, Met 229, Met 247, and Met 317) were selected as the mutation sites and individually replaced with leucine. In the presence of 500 mM H(2)O(2) at 35°C for 5 h, the ...

Mass Flow Controllers are complex mechatronic devices the design of which involves many techniques and skills in various scientific domains. Due to the slow response time of the sensors embedded in such devices, it is critically important to control gas flow variations in processes used in semiconductor industry. This paper shows how a digital controller for MFCs can be mathematically computed ...

Dielectric properties of textile materials have been used in process and quality control in relation to the moisture content, unevenness, drying, static generation, etc. Although dielectric properties of fibres and fibrous assemblies have been the subject of study of many researchers for a long time, the understanding of the subject, however, is still incomplete. With the advent of new characte...

The International Technology Roadmap for Semiconductors (ITRS) identifies production test data as an essential element in improving design and technology in the manufacturing process feedback loop. One of the observations made from the highvolume production test data is that dies that fail due to a systematic failure have a tendency to form certain unique patterns that manifest as defect cluste...

Tobacco packaging and labeling policies have emerged as prominent and cost-effective tobacco control measures. Although packaging policies have primarily focused on health warnings, there is growing recognition of the importance of packaging as a marketing tool for the tobacco industry. The current paper reviews evidence on the potential impact of standardizing the color and design of tobacco p...

Over the past half century, one of the most familiar and effective arguments put forth by the tobacco industry to defend its business and minimise its regulation is that it generates net economic benefits to society. Put simply, industry advocates claim that taxation, profits, and employment associated with tobacco far outweigh any costs imposed on societies and in particular on health care sys...

[Foreign trade involves tasks that may be subject to language barriers, such as researching foreign markets, communicating with counterparties and marketing products to foreign consumers. Language skills have a wage premium that is determined by local and worldwide supply and demand for language services, and the premium is specific to each country and pair of languages. I construct a novel mea...
