16. Towards dynamic array processing for GNSS software receivers
Sammanfattning : Since the very first Global Positioning System satellite was launched in 1978, Global Navigation Satellite Systems (GNSS) have developed into a world wide utility, providing everyone with an affordable method for determining accurate position and time. However, the system is susceptible to multipath (when the signal is reflected off a surface), interference (other signals in the same frequency band) and attenuation (for example canopies blocking some of the signal energy).

17. Path-planning with obstacle-avoiding minimum curvature variation B-splines
Sammanfattning : We study the general problem of computing an obstacle-avoiding path that, for a prescribed weight, minimizes the weighted sum of a smoothness measure and a safety measure of the path. We consider planar curvature-continuous paths, that are functions on an interval of a room axis, for a point-size vehicle amidst obstacles. LÄS MER
18. Improved techniques for self-diagnosis of an ultrasonic flow meter
Sammanfattning : For both economical and environmental raisons, accurate measurements of energy consumptions are important. The District Heating Industry supplies buildings and private houses of a whole city in hot water through a network. LÄS MER
19. Self-diagnosis techniques and their applications to error reduction for ultrasonic flow measurement
Sammanfattning : Flow metering plays a major role in modern life. In the process industry, flow metering is critical in industries ranging from food processing to cosmetics. It is also essential in custody transfer or billing, as flow meters are present in gas pumps and district heating substations. LÄS MER
20. Non-contact measurement systems in robotics and telerobotics
Sammanfattning : In robotics, and particularly in telerobotics, non-contact measurement methods are widely used. In this thesis, systems are investigated with the range camera as the main sensor component. It is desirable that remotely controlled robot systems have a high degree of autonomy. LÄS MER
