A s most of us are aware, recent technological advances offer tremendous promise in bringing the benefits of rich computational capabilities to dynamic, diverse situations in everyday life. However, much of this promise remains unfulfilled. We can’t yet use this enormous computing power to facilitate our day-to-day lives and regularly deliver compelling ubiquitous computing applications. Our si...

In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important requirements for the development of our system are presented. In our approach, we break down the rendering shader into areas containing code for different computations, which ...

Space communication systems are plagued by complexity resulting in limited access to orbiting satellites and high mission operation costs that ultimately reduce mission yields and capabilities. In particular, ground stations, the access point between space and terrestrial networks, suffer from monolithic designs, narrow interfaces, and reliability issues that raise significant engineering barri...

How does knowledge come to be manipulable and flexible, and transferable to other tasks? These are issues which remain largely untackled in connectionist cognitive modelling. The Representational Redescription Hypothesis (RRH) (Karmiloff-Smith, 1992b) presents a framework for the emergence of abstract, higher-order knowledge, based on empirical work from developmental psychology. The RRH claims...

Automatic code synthesis from dataflow program graphs is a promising high-level design methodology for rapid prototyping of multimedia embedded systems. Memory efficient code synthesis from dataflow models has been an active research subject to reduce the gap in terms of memory requirements between the synthesized code and the hand-optimized code. However, existent dataflow models have inherent...

Designing web sites is a complex task. Ad-hoc rapid prototyping easily leads to unsatisfactory results, e.g. poor maintainability and extensibility. However, existing web design frameworks focus exclusively on data presentation: the development of specific functionalities is still achieved through low-level programming. In this paper we address this issue by describing our work on the integrati...
