Over the last few decades, several usability knowledge-based systems have been developed to provide user interface designers with usability knowledge (e.g., heuristics, usability guidelines, standards). Such systems are intended to assist designers during the design process, and to improve the usability of the user interface being designed. However, the assumption that such systems actually imp...

Knowledge based engineering (KBE) is a relatively young technology with an enormous potential for engineering design applications. Unfortunately the amount of dedicated literature available to date is quite low and dispersed. This has not promoted the diffusion of KBE in the world of industry and academia, neither has it contributed to enhancing the level of understanding of its technological f...

With increasing complexities and a component-based design style the handling of unknown values (e. g., at the interface of components) becomes more and more important in electronic design automation (EDA) and production processes. Tools are required that allow an accurate modeling of unknowns in combination with algorithms balancing exactness of representation and efficiency of calculation. In ...

From a software design perspective, access control policies are requirements that must be addressed in a design. For example, access control policies are constraints that determine the type of access authorized users have on information resources. In this paper, we show how one can formulate access control policies as a policy model, formulate an access control aspect model that enforces polici...

Collaborative settings of multi-disciplinary teams separated across geographical and temporal boundaries call for an integrated framework to support intelligent and distributed CAD. This paper presents a framework to improve the ability to represent, capture, and reuse design rationale by using: computer-supported design rationale model (DRIMER) to capture design rationale; collaborative tools ...

Components-based development is promising in improving software development productivity and software quality by re-using existing well-tested software components. However, one of the challenges of component-based development is how to integrate various components in software systems. In this paper, an approach is presented to apply design patterns to component integration. This approach uses a...

Cosmetic products are inherently personal. Many people rely on product reviews when choosing to purchase cosmetics. However, reviewers can have tastes that vary based on personal, demographic or cultural background. Prior work has discussed methods for generating attribute-based explanations for item ratings on cosmetic products, based on associated text-based reviews. This paper focuses on eva...

This paper discusses the issues related to the application of wireless communication and positioning technologies to the development of hand-held electronic tour guides. These issues are discussed presenting HIPS, a project recently funded by the European Commission that aims at developing a hand-held electronic tour guide allowing tourists to navigate both the physical space and a related info...

This paper describes a design support system which goes beyond the support facilities offered by the current generation of CASE tools. We have examined the entire design process, and we propose that the early stages of conceptual design need a more flexible system than is currently offered by existing design methods. Our toollthe Designer's Notepad (DNp)) allorvs rough designs to be created and...

The politics of development ideology and global leadership set the scene for sport (for) development in South Africa. Diverse research agendas and donor requirements informed research whereby indigenous knowledge systems could be accessed in a collaborative venture of knowledge production. A discussion of three distinct and interrelated models, based on the rationale of Mintzberg (2006), afford...
