Context: The participation of users in the design process is recognized as a positive and a necessary element as artifacts suit their needs. Two complementary approaches of users' involvement co-exist: the user-centred design and the participatory design. These approaches involve learning process from users to designers and vice versa. However, there has no research in design of virtual reality...

In this note I discuss some issues in filter design for equalization of sound systems. The emphasis is on rationale, not on experiments, and I will focus on a few common misunderstandings. I will briefly describe the basic concepts used in sound equalization, such as FIR and IIR filters, minimum and linear phase and present basic mathematical facts as well as give a background to the philosophy...

Research and development on Computer Aided Architectural Design often focuses on simulating a building as a digital model. Our research on the early design stages explores concepts we feel are lacking in current design tools and research projects. Building models are usually static models, serving as a snapshot of the design. We aim to support design phase and scale level transitions, to better...

The increasing complexity of modern telecommunication systems is one of the main issues encountered in most telecom products. Despite the plethora of methods and tools for efficient system design, verification and validation phases are still consuming significant part of the overall design time. The proposed approach outlines the use of the B method/language for producing correct-by-constructio...

Multitude parameters involved in the design process of a reconfigurable accelerator which is exploited in embedded systems brings about a remarkable complexity and large design space. One effective technique is design space exploration which is capable to find a right balance between the different design parameters. Quantitative design approach is an alternative which uses the data collected fr...
