1. 6. 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. 7. Computational Models for Animating 3D Virtual Faces

   Författare :Marco Fratarcangeli; Robert Forchheimer; Marco Schaerf; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Automatic synthesis of facial animation in Computer Graphics is a challenging task and although the problem is three decades old by now, there is still not a unified method to solve it. This is mainly due to the complex mathematical model required to reproduce the visual meanings of facial expressions coupled with the computational speed needed to run interactive applications.

4. 8. Tracking and threat assessment for automotive collision avoidance

   Författare :Andreas Eidehall; Fredrik Gustafsson; Aris Polychronopoulos; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; collision avoidance; lane guidance; state estimation; target trackin; Kalman filter; centralized filtering; threa; Automatic control; Reglerteknik;

   Sammanfattning : This thesis is concerned with automotive active safety, and a central theme is a new safety function called Emergency Lane Assist (ELA). Automotive safety is often categorised into passive and active safety, where passive safety is concerned with reducing the effects of accidents and active safety aims at avoiding them. LÄS MER

5. 9. On mechanical characterization and multi-scale modeling of Lithium-ion batteries

   Författare :Priyank Gupta; Peter Gudmundson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; constitutive modeling; U-shape bending tests; electrochemistry; multi-scale modeling; three-dimensional laminate theory.; Solid Mechanics; Hållfasthetslära;

   Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER

7. 10. Aeroelastic Concepts for Flexible Aircraft Structures

   Författare :Sebastian Heinze; Dan Borglund; Rick Lind; KTH; []
