  2. 11. Image Reconstruction and Optical Flow Estimation on Image Sequences with Differently Exposed Frames

    Author : Tomas Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple camera settings; human visual system; super-resolution; optical flow; high dynamic range; digital camera system; image reconstruction; motion analysis; inverse problem;

    Abstract : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

  4. 12. Studying Buoy Motion for Wave Power : Experiments at the Lysekil Research Site

    Author : Simon Tyrberg; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Since 2002, the Division for Electricity at Uppsala University has been running the Lysekil project. The project is an attempt to construct and evaluate a technology for extracting electrical energy from the motion of ocean waves. The idea is to let this up-and-down motion drive a linear generator.

  5. 13. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

    Author : Bernt Nilsson; Aarne Halme; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

    Abstract : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. READ MORE

  6. 14. Structure-dynamics relationships in perovskite oxyhydrides and alkali silanides

    Author : Carin Eklöf-Österberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen storage material; long range diffusion; oxyhydride; neutron scattering; localized motion; hydride ion conduction; hydrogen dynamics;

    Abstract : This thesis focuses on investigations of the local structure and dynamics of two classes of hydrogen-containing, energy relevant, materials; perovskite type oxyhydrides BaTiO3-xHx and alkali silanides ASiH3 (A = K and Rb). In the area of oxyhydrides, which are of relevance for the development of electrolytes in fuel cells and batteries, the aim is to elucidate the dynamics and electronic character of the hydrogen species in the materials.

  7. 15. Context-aware Human Motion Prediction for Robots in Complex Dynamic Environments

    Author : Andrey Rudenko; Kai Arras; Achim Lilienthal; Thierry Fraichard; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; robotics; human motion prediction; activity forecasting;

    Abstract : Understanding human behavior is a key skill for intelligent systems that share physical and emotional spaces with humans. One of the main challenges to this end is the ability of such systems to make accurate predictions of human motion. READ MORE
