The paper describes an approach, which we developed to assess the expected quality of software for a huge governmental system. The assessment was done on behalf of the customer, and not of the development company, and was performed within two years along with the software development process. Our approach was based on a modification to GQM and was focused on the evaluation of the quality of met...

Introduction. This paper reports an exploratory study examining how users participate in social tagging activities in a scholarly digital library environment to learn about their motivations, behaviour, and practices. Method. This study was conducted in two phases: a survey to investigate usage and attitudes of social tagging tool, and a task-based user study on tagging practices in Theses@UMal...

The Web is the most pervasive collaborative technology in widespread use today; however, access to the web and its many applications cannot be taken for granted. Web accessibility encompasses a variety of concerns ranging from societal, political, and economic to individual, physical, and intellectual through to the purely technical. Thus, there are many perspectives from which web accessibilit...

Brushwork and ink dispersion make it difficult to render 3D common objects in the style of sumi-e painting. We use sphere mapping with brush texture and an image processing techniques to simulate brushstrokes and ink dispersion. The whole process is implemented in shaders running on Graphics Process Unit (GPU) that allows fast and highquality rendering 3D polygonal models in the style of sumi-e...

This paper presents new practical approach to automated formal modeling and validation of quality requirements. It relies on two paramount software industry standards: ISO/IEC 9126 for software quality and XML for formal notation. The xNoFun language allows composing formal quality models not only manually but via requirement management CASE tool IBM Rational RequisitePro. Efficient runtime mod...

* Enterprise Application Integration † Co-financed by FONACIT through the S1-2001000792 Abstract Software integration has been a solution to the problem of connecting dissimilar systems for many years. This integration is still a challenging issue. EAI (Enterprise Application Integration) is defined as the process of integrating enterprise systems with existing applications. Since software inte...

The determination of the maximal ranks of a set of a given type of tensors is a basic problem both in theory and application. In statistical applications, the maximal rank is related to the number of necessary parameters to be built in a tensor model. JaJa [JA] and Sumi et. al [SMS1] developed an optimal bound theory based on Kronecker canonical form of the pencil of two matrices. Theory of mat...

by Dominik Buszko iii ACKNOWLEDGMENTS I would like to express my sincere gratitude to my advisor, Dr. Abdelsalam (Sumi) Helal, for providing me with an opportunity to work in this exciting area and for providing feedback, guidance, support, and encouragement during the course of this project and my graduate academic career. I would like to take this opportunity to thank my family and my girlfri...

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...

To specify quality requirements for Web 2.0 applications we propose an integrated approach which considers features for contents, functionalities and services. In this work we discuss how to model internal quality, external quality and quality in use views taking into account not only the software characteristics – as those specified in the ISO 9126-1 quality modelsbut also the own features to ...
