Suibokuga is a style of monochrome painting characterized by the use of Chinese black ink (sumi), a complex interaction between brush, ink and paper, and such visual features as Noutan (shade), Kasure (scratchiness), and Nijimi (blur). In this paper we present a simple behavioural model of water and ink particles based on a 2D cellular automaton computational model, and its application to a Sui...

In this work we propose a methodology named QUEM (Quantitative Usability Evaluation Model) for quantitative usability evaluation of e-commerce websites. Many e-commerce websites lack user friendliness. The main factor that prevents these firms to conduct usability testing is the high costs and the need for usability experts. In this work, ISO/IEC 9126-1:2001 quality model was selected as a basi...

This paper provides a systematic evaluation framework for comparing model transformation approaches, based upon the ISO/IEC 9126-1 quality characteristics for software systems. We apply this framework to compare five transformation approaches (QVT-R, ATL, Kermeta, UMLRSDS and GrGen.NET) on a complex model refactoring case study: the amalgamation of apparent attribute clones in a class diagram. ...

The users who use ready to use software product had better get the products’ quality information with classified by some kind of global standard metrics or technique for their evaluation. But many of those software products’ companies don’t provide the quality information because of the products are developed by their own development and evaluation process. But those users want to get quality i...

Maintainability is typically described initially as a non functional requirement at the system level. Systems engineers must subsequently apportion these system requirements very carefully as either software or hardware requirements to conform to the maintainability requirements of the system. A number of concepts are provided in the ECSS, ISO 9126, and IEEE standards to describe the various ty...

A large number of evaluation metrics exist for machine translation (MT) systems, but depending on the intended context of use of such a system, not all metrics are equally relevant. Based on the ISO/IEC 9126 and 14598 standards for software evaluation, the Framework for the Evaluation of Machine Translation in ISLE (FEMTI) provides guidelines for the selection of quality characteristics to be e...

Recent proliferation of mobile market has swiftly increased the competition in mobile software market, new technology and new devices are emerging at phenomenal speed. As the number of mobile applications is increasing at daily rate, quality is becoming major issue. So mobile software organization need some quality model as guideline to improve and maintain quality of application under developm...

As Component-based Software Development (CBSD) starts to be effectively used, some software vendors have commenced to successfully sell and licence commercial off-the-shelf (COTS) components. One of the most critical processes in CBSD is the selection of the COTS components that meet the user’s requirements. Current proposals have shown how to deal with the functional aspects of this evaluation...

The success of Web applications is constrained by two key features: fast evolution and usability. Current Web engineering approaches follow a "unified" development style which tends to be unsuitable for applications that need to evolve fast. Moreover, according to the quality standard ISO 9126-1, usability is a key factor to obtain quality systems. In this paper, we show how to address usabilit...
