The purpose of this report is to assess the relevance of the measurement of the spectrally resolved distribution of radiation in tokamak boundary plasmas. This assessment is important and urgent in view of the recent ambition to design and construct a multi-camera configuration for hyper imaging spectroscopy1 …

In this paper the authors illustrate developments in sensor technology with a number of examples. From their own research they discuss radar, image processing and sensor networks. Radar performance is affected by propagation characteristics of electromagnetic waves. Experience has shown that this may …

This work has: •Examined, compared and evaluated 22 programming languages and environments for parallel computing on multi-core CPUs and GPUs •Chosen to use OpenMP as the standard for multi-core CPU programming and OpenCL for GPU programming •Re-implemented a number of standard and well-known algorithms …

Axon Digital Design develops modular systems and equipment for audio and video signal processing and monitoring, mainly aimed at the broadcasting industry. The recent successes of 3D film productions have pushed the consumer TV market into a new era: 3D television in the living room. One fundamental …

Robots need sensors to operate properly. Using a single image sensor, various aspects of a robot operating in its environment can be measured or monitored. Over the past few years, image sensors have improved a lot: frame rate and resolution have increased, while prices have fallen. As a result, data …

The human memory has an associative nature. Association and mental visualization combine skills and structures of the left and right brain halves. It is easier to remember pictures, photographs or drawings than words or sentences. In fact, it usually takes a lot of effort to remember words and sentences …

Described are the results of a study that was set up to get insight into the appreciation of students for distance learning, especially concerning online lab-experiments. We wanted to know whether an online lab-experiment is more or less effective than a regular one and how it can be used in IPD-projects. …

Key factors in the public acceptance of biometric systems are non-intrusiveness, ease of use, and trust. In this paper we propose a biometric identity verification system consisting of a non-intrusive virtual mirror interface, and a face verifier using fractal coding to store the biometric template on …

In contemporary image databases one finds many images with the same image content but perturbed by zooming, scaling, rotation etc. For the purpose of image recognition in such databases we employ features based on statistics stemming from fractal transforms gray-scale images. We show how the features …

Retrieval practice enhances long-term retention more than restudying; a phenomenon called the testing effect. The fuzzy trace explanation predicts that a testing effect will already emerge after a short interval when participants are solely provided with semantic cues in the final test. In the present …
