1. Blue Laser Source for Laser-Induced Fluorescence
Sammanfattning : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. LÄS MER
2. Environmental Monitoring by Multi-Spectral Lidar Techniques
Sammanfattning : Multi-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been applied. LÄS MER
3. Mobile robot fault detection using multiple localization modules
Sammanfattning : Most applications in service robotics require that the position of the robot is accurately known. Faults affecting the localization system can thus have serious effects on the overall performance. LÄS MER
4. Non-Invasive Monitoring of Architectural Heritage
Sammanfattning : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning. LÄS MER
5. On Robot Feedback from Range Sensors : Reliable Control by Active Reduction of Uncertainty and Ambiguities
Sammanfattning : This thesis is on modelling and experimental tests when non contact sensing isused for feedback control in robotics. The motion of the robot is to be controlled relative to objects in the surrounding workspace during operations like gripping/docking, surface following, shape measuring etc. LÄS MER
