The preferences of children and adults were compared with respect to each of the following color image quality attributes: image brightness, saturation, sharpness, color balance (+M/+G), hue rotation, and contrast. It was found that the children had no strong preferences for sharpness or contrast. There was no statistical evidence that they disagreed with adults as to the optimal level of brigh...

Software quality is the degree to which software possesses a desired combination of attributes (e.g., reliability, interoperability). In this paper we describe a few principles for analyzing a software architecture to determine if it exhibits certain quality attributes. We show how analysis techniques indigenous to the various quality attribute communities can provide a foundation for performin...

Refactoring to patterns allows software designers to safely move their designs towards specific design patterns by applying multiple low-level refactorings. There are many different refactoring to pattern techniques, each with a particular purpose and a varying effect on software quality attributes. Thus far, software designers do not have a clear means to choose refactoring to pattern techniqu...

Quantitative measurement of software reliability remains an elusive goal. Simultaneously, there is an ever increasing critical dependency on software-based systems in the human infrastructure. There is a great deal of research in addition to well-intentioned methods and practices focused on improving the reliability of software-based systems. To date, most of which still only yields qualitative...

This research addresses difficulties in measuring e-commerce success by implementing the DeLone and McLean (D&M) model of IS success (1992, 2003) in an e-commerce environment. This research considers the influence of quality on e-commerce success by measuring the information quality and system quality attributes of an e-commerce system and the intention to use, user satisfaction and intention t...

One solution to process and analysis of massive graphs is summarization. Generating a high quality summary is the main challenge of graph summarization. In the aims of generating a summary with a better quality for a given attributed graph, both structural and attribute similarities must be considered. There are two measures named density and entropy to evaluate the quality of structural and at...

For two years, we have been involved in a challenging project to develop a new architecture for an industrial transportation system. The motivating quality attributes to develop this innovative architecture were flexibility and openness. Taking these quality attributes into account, we proposed a decentralized architecture using multiagent systems (MASs). A MAS consists of multiple autonomous e...

One of the main objectives of developing component-based software systems is to enable integration of components which are perceived as black boxes. While the construction part of the integration using component interfaces is a standard part of all component models, the prediction of the quality attributes of the component compositions is not fully developed. This decreases significantly the va...

INCITS W1 is the U.S. representative of ISO/IEC JTC1/SC28, the standardization committee for office equipment. In September 2000, INCITS W1 was chartered to develop an appearance-based image quality standard. (2) The resulting W1.1 project is based on a proposal that perceived image quality could be described by a small set of broad-based attributes. There are currently five ad hoc W1.1 teams, ...

John Morley [email protected] A system designer faces several challenges when specifying security for distributed computing environments or migrating systems to a new execution platform. Business stakeholders impose constraints due to cost, timeto-market requirements, productivity impact, customer satisfaction concerns, and the like. And users exercise power at the desktop over computing reso...
