The embedded system development methodology has not been as well established as the development methodology in software engineering. Involving inter-disciplinary activities in the development of hardware and software need to be further considered when developing an embedded system. This paper presents a new development model for an embedded system by the hybridization of selected development me...

In this article it is developed and it analyze a computational model based on the concepts of the Fuzzy Logic that it will allow the calculate the value of Usability to final user’s of software developments based on the Norma ISO/IECE 9126-1:2.001, and based on the Fuzzy Model of Takagi Sugeno Kang. For this model’s development it becomes necessary to keep in mind a series of attributes that th...

Usability has become a critical quality factor of software systems in general, and especially important regarding Web-based applications. Measuring quality is the key to developing high-quality software, and it is widely recognised that quality assurance of software products must be assessed focusing on the early stages of the development process. This paper describes a controlled experiment ca...

Making major changes in enterprise information systems, such as large IT-investments, often have a significant impact on business operations. Moreover, when deliberating which IT-changes to make, the consequences of choosing a certain scenario may be difficult to grasp. One way to ascertain the quality of IT-investment decisions is through the use of methods from decision theory. This paper pro...

According to IEEE, software quality is the degree to which software possesses a desired combination of attributes. Quality attributes have been of interest to the software community since 1970 and in the past few years this interest has increase. However, still is not clear how product quality should apply in the development process. The need to know what quality characteristics influence a spe...

The original conceptualization of usability was ease of use, this was later expanded into a multi-dimensional construct in ISO standards and usability literature. Such an expansion is seen as an improvement, since cross-study comparison or benchmarking cannot objectively be done without a common set of usability components being defined. The current issue lies in how these components are operat...

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...
