Context: Software products have requirements on various software quality attributes such as safety and performance. Development teams use various specific techniques to achieve these quality requirements. We call these “Quality Attribute Techniques” (QATs). QATs are used to identify, analyse and control potential product quality problems. Although QATs are widely used in practice, there is no s...

Context: Cost advantage has been one of the primary drivers of successful offshoring engagements of Indian software and services companies. However, the emphasis has shifted to the ability of the vendors to provide hig...

In process of software architecture design, different decisions with system-wide impacts are made. An important decision of design stage is the selection of appropriate software architecture style. Since quantitative impacts of styles on quality attributes have not been studied yet, their application is not systematic. Since Reliability is one of the essential quality requirements of software s...

The Internet has become an important resource for information. The Internet presents information through web pages and hyperlinks. However, this mode of presentation is not always useful for every purpose. Internet searches are designed to locate and to present information more effectively. The efficiency and usefulness of Internet searches are becoming more and more dependent on the design of ...

In this paper, multidimensional models of image quality are discussed. In such models, alternative images, for instance, obtained through different processing or coding of the same scene, are represented as points in a multidimensional space. The positioning is such that the correlation between geometrical properties of the points and the subjective impressions mediated by the corresponding ima...

Context. Software re-engineering has been identified as a business critical activity to improve legacy systems in industries. It is the process of understanding existing software and improving it, for modified or improved functionality, better maintainability, configurability, reusability, or other quality goals. However, there is little knowledge to integrate software quality attributes into t...

Frameworks have fundamental impact on software quality of robot control systems. We propose systematic framework design aiming at high levels of support for all quality attributes that are relevant in the robotics domain. Design decisions are taken accordingly. We argue that certain areas of design are especially critical, as changing decisions there would likely require rewriting significant p...

Successful provision of services in pervasive networks represents a major challenge. The requester of a service or resource should be able to decide whom to rely on, not only depending on the apparent QoS that various providers offer, but also on the trustworthiness of the providers, as well as their mobility patterns. Existing approaches offer a rather simplistic solution to the problem: eithe...

This paper describes a method used for evaluating sound quality of 4 hearing aid products using expert assessors for a sensory profiling test and a preference test. Hearing aids were evaluated by trained normal-hearing listeners in 7 different sound environments that were selected to represent some of the common hearing aid user situations. The scenarios were reproduced in a standard listening ...

A small number of general visual attributes have been recognized as essential in describing image quality. These include micro-uniformity, macro-uniformity, colour rendition, text and line quality, gloss, sharpness, and spatial adjacency or temporal adjacency attributes. The multiple-part International Standard discussed here was initiated by the INCITS W1 committee on the standardization of of...
