The paper presents a process modelling-based Requirements Engineering Framework, where advanced requirements engineering techniques are combined with software quality modelling approaches to better assist and drive analysts and stakeholders to an early definition and validation of the desired system functionality and quality attributes, while supporting the redesign of the application context t...

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases particularly in the context of systems composed of a large set of autonomous data sources where integrating data having different freshness may lead to semantic problems. This paper addresses the problem of evaluating data freshness in a data integration syst...

Software quality is an important issue in the development of successful software application. Many methods have been applied to improve the software quality. Refactoring is one of those methods. But, the effect of refactoring in general on all the software quality attributes is ambiguous. The goal of this paper is to find out the effect of various refactoring methods on quality attributes and t...

The popularity and growth of the "Information SuperHighway" have dramatically increased the number of information sources available for use. Unfortunately, there are significant challenges to be overcome. One particular problem is c o n t e x t interchange, whereby each source of information and potential receiver of that information may operate with a different context, leading to largescale s...

Contextual processing is a new emerging field based on the notion that information surrounding an event lends new meaning to the interpretation of the event. Data mining is the process of looking for patterns of knowledge embedded in a data set. The process of mining data starts with the selection of a data set. This process is often imprecise in its methods as it is difficult to know if a data...

The development of Web Applications has some special characteristics, such as very short Time-to-Market, parallel development and requirements that are not prioritized. This makes it hard to address quality attributes in a systematic way, to prioritize requirements and to resolve conflicts between them. The use of trade-off methods such as QFD will help to prioritize the “right” requirements an...

To evaluate the power quality scientifically and reasonably is of important practical significance. This paper applies attribute mathematics to the power quality evaluation, and puts forward a combination weighting method which is based on similarity weight method and AHM weighting method. At last, the attribute comprehensive evaluation method put forward in the paper is tested by using the mea...

The United States Pharmacopeial Convention (USP) Therapeutic Peptides Expert Panel was formed in 2013 to evaluate quality attributes for synthetic peptides based on currently available regulatory guidance and expectations. Public quality standards for drug products and drug substances are developed by USP and enforceable by FDA. This series of three articles by the Panel explores the current ma...

The popularity of distributed computing environments and the growth of the “Information SuperHighway” have dramatically increased the number of data bases available for use. Unfortunately, there are significant challenges to be overcome. One particular problem is context interchange, whereby each source of information and potential receiver of that information may operate with a different conte...
