Konferensbidrag (refereegranskat)abstract
- A need to apply the massively parallel computing paradigm in embedded real-time systems is foreseen. Such applications put new demands on massively parallel systems, different from those of general purpose computing. For example, time determinism is more important than maximal throughput, physical distribution is often required, size, power, and I/O are important, and interactive development tools are needed. The paper describes an architecture for high-performance, embedded, massively parallel processing, featuring a large number of nodes physically distributed over a large area. A typical node has thousands of processing elements (PEs) organized in SIMD mode and is the size of the palm of a hand, Intermodule communication over a scalable optical network is described. A combination of wavelength division multiplexing (WDM) and time division multiplexing (TDM) is used. © 1994 IEEE.

- This paper presents a hardware architecture and a software tool needed for future autonomous robots. Specific attention is given to the execution of artificial neural networks and to the need for a good inspection and visualization tool when developing this kind of systems. Achievable performance using state-of-the-art technology is estimated and module miniaturization issues are discussed. © 1994 IEEE.

Gabor phase in boundary tracking and region segregation
- 1993

Ingår i: Proc. DSP & CASES Conf., Nicosia, Cyprus. ; , s. 229-234

Konferensbidrag (refereegranskat)abstract
- An eye movement mechanism with the task of tracking textureboundaries has been simulated. Gabor phase information has been dynamically used in order to track regionboundaries. The tracking has been initiated manually froma point nearby a texture boundary with an initial boundary direction estimate. A filter selection strategy depending onthe azimuth angles of the receptive fields, and a control mechanism relying onphase discontinuites which are computed through means of magnitudesand magnitude of means of the complex filter responses have been devised.The experiments suggest that letting the Gabor phase play a dynamic role in boundary tracking results in accuratetracking at pixel resolution even when the texturesdiffer only in phase. As a by product tracking segregates textured regions.

Konferensbidrag (refereegranskat)abstract
- At small Halmstad University we have, for the past 13 years, a unique educational program in innovation engineering. The three-year educational program provides the candidates with a broad technical and economical education with special emphasise on handling the innovation process and running new product development projects. An optional fourth year, entitled innovation management, focuses on leadership, innovation, and the choices of technology in multinational companies. This is the summing up of 13 years of experience, during which 286 innovation engineers received an education (even if 22% left with one or two unwritten exams).

- A system has been developed where data from a Mk3 VLBI processor can be read into the AIPS-package. Multiband and single-band delays can then be fitted globally by station. The technique has been used to phasereference a background to two radiogalaxies in the Abell cluster A2634.
