1. 1. On Robot Feedback from Range Sensors : Reliable Control by Active Reduction of Uncertainty and Ambiguities

   Författare :Jonas Nygårds; John Hallam; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot gripping and docking; LQG-feedback; posture estimation; Gaussian sum; optronic sensing; sheet of light range camera; time-of-flight laser; specular reflection s; multiple scattering; range ghosts ; active reduction of ambiguities; reliability; uncertainty; tolerances;

   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

3. 2. Range Camera Imaging : From Human Body Measurements to Very Large 3D Points Scenes Visualization

   Författare :Gaël Neuez; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D visualization; EASYTEX; anatomical landmarks; body scanner; range camera; 2D image projections; structured light; octree data structure;

   Sammanfattning : The use of camera range imaging for the purpose of 3-dimensional representation and non-contact measures is widely used in industry, medicine, computer-aided design and other areas. Different range imaging methods can be applied, such as stereo, laser sheet of light, and structured light. LÄS MER

4. 3. Optical diagnostics of Soot in optically dense sprays

   Författare :Raul Lima Ochoterena; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Soot diagnostics in engines can be carried out with optical methods that have the potentialfor high temporal and spatial resolution. Some of these methods were appliedto study diesel spray combustion in the Chalmers High Pressure, High Temperature(HP/HT) spray rig. LÄS MER

5. 4. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

   Författare :Ronald Whiddon; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

   Sammanfattning : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. LÄS MER

7. 5. Fibre suspension flocculation under simulated forming conditions

   Författare :Huawei Yan; KTH; []
   Nyckelord :;

   Sammanfattning : A flow loop system for study of fibre flocculation insuspensions has been developed. The system is designed tosimulate the flow conditions in a paper machine headbox. It isequipped with a radial distributor feeding a step diffuser pipepackage, after which the flow is contracted in a 2-D nozzle. LÄS MER
