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 …

Ultrasonic Verification is a new method for the monitoring large surface areas of CFRP by ultrasound with few sensors. The echo response of a transmitted pulse through the structure is compared with the response of an earlier obtained reference signal to calculate a fidelity parameter.

Anomaly detection is a key factor in the processing of large amounts of sensor data from Wireless Sensor Networks (WSN). Efficient anomaly detection algorithms can be devised performing online node-local computations and reducing communication overhead, thus improving the use of the limited hardware …

The maturing field of Wireless Sensor Networks (WSN) results in long-lived deployments that produce large amounts of sensor data. Lightweight online on-mote processing may improve the usage of their limited resources, such as energy, by transmitting only unexpected sensor data (anomalies). We detect …

Uit onderzoek is gebleken dat lage CO2 concentraties van zo’n 1000 ppm al invloed hebben op de concentratie en productiviteit van werknemers. In kantoorgebouwen, vergaderruimtes en schoolgebouwen komt het nog wel eens voor dat de CO2 concentratie hoger is dan de gestelde grens van 1000 ppm. Daarom is …

Athor supplied : "This paper describes an agent-based architecture for domotics. This architecture is based on requirements about expandability and hardware independence. The heart of the system is a multi-agent system. This system is distributed over several platforms to open the possibility to tie …

Presentatie van Niels van Steenis en Hans Appel op 15 april 2013 voor provincie Groningen.

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 …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …
