The requirement phase in the software development process is typically formulated using UML diagrams, including use cases and conceptual class diagrams. It is claimed that UML is suitable for modeling at the domain level; accordingly, many enhancements to these diagrams have been proposed to achieve a more comprehensive representation of functionality of the system from the conceptual (computat...

In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. These aspects are mainly considered during later stages of the design process. However, in order to improve the foundations for decision-making, this paper presents methods that are intended to increase the engineering knowledge i...

Design is an activity that translate a set of requirements in a feasible product by considering constraints coming from physics, technology avaibility and designer preferences. Configuration is a special case of design in which the product component properties are already predefined. In this paper, the design of a new concepts (or the validation of existing ones) is considered as a configuratio...

Self-optimizing systems are technical systems with the ability to learn, communicate with each other, and optimize their behaviour autonomously in response to environmental changes. The operation of such systems requires close interaction between mechanics, electronics, control engineering and software engineering. This paper addresses the conceptual design of controllers based on the principle...

As the key visual displayand processingelement of information super highway nodes, computer graphics is advancing into dynamic and higher dimensional visual worlds. So is visual algorithms to program visual worlds as the contents of information super highways. This research presents a drastic approach in designing visual algorithms to construct visual worlds. The address is on the most critical...
