Pain does not only cause psychological distress, but psychological distress also amplifies pain through neurological mechanisms. Treatment of both chronic and acute pain would benefit from acknowledging the psychological mechanisms of pain neurophysiology. LÄS MER
23. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band
Sammanfattning : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.

24. Design of Optimal Control Processes for Closed-Loop Chain SCARA-Like Robots
Sammanfattning : The design of optimal control processes for closed-loop chain SCARA-like robots is the subject of this thesis. In comparison with the well-known SCARA robot, the proposed new structure is characterized by the incorporation of an additional powered actuator, several unpoweredactuators and an additional link that gives a closed-loop chain robot.
