The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

A Bayesian approach to optimal sensor placementCameron, Alexander John January 1989 (has links)
By "intelligently" locating a sensor with respect to its environment it is possible to minimize the number of sensing operations required to perform many tasks. This is particularly important for sensing media which provide only "sparse" data, such as tactile sensors and sonar. In this thesis, a system is described which uses the principles of statistical decision theory to determine the optimal sensing locations to perform recognition and localization operations. The system uses a Bayesian approach to utilize any prior object information (including object models or previously-acquired sensory data) in choosing the sensing locations.

Operating Performance of Automated Pedestrian Detectors at Signalized IntersectionsFoord, Jonathan Gregory 19 January 2011 (has links)
The research analyzes the operating performance of three commercially available curbside automated pedestrian detectors (APDs) (infrared and stereovision, passive infrared, and a microwave detector) for the actuation of pedestrian walk phases as a function of winter weather and temperature variations at signalized intersections in terms of detector selectivity and sensitivity. Two sites were selected for field analysis in Winnipeg, Manitoba Canada. Based on a sample of 8,225 detections at the two sites, the research found that overall sensitivity rates of the APDs ranged from 62 to 98 percent while selectivity rates were generally below 50 percent. Regardless of site, the infrared/video APD had the second highest sensitivity and highest selectivity rates of all APDs analyzed. The infrared APD had the highest sensitivity and lowest selectivity rates, and the microwave APD had the lowest sensitivity and second highest selectivity.
