1. Quadruped robot control and variable leg transmissions
Sammanfattning : The research presented in this thesis regards walking of quadruped robots, and particularly the walking of the Warp1 robot. The motivation for the robot is to provide a platform for autonomous walking in rough terrain. The thesis contains six papers ranging from development tools to actuation of robot legs. LÄS MER
2. On Rolling Variators, A study of power transmitting rolling variators when changing speed ratio
Sammanfattning : The introduction of the concept Rolling Variators is proposed for rolling contact continuously variable transmission.A theoretical study of rolling variators when changing the speed ratio during power transmission is presented. LÄS MER
3. On some positive effects of swirling flow for the continuous cast mould billets
Sammanfattning : Continuous caster moulds are the last and most important stage in the steelmaking process, where inclusions can either be generated or removed. With increasing casting speed using conventional immersion nozzles critical problems, such as unstable bulk mould flow have been noticed. LÄS MER
4. Hyperemic Brachial Artery Blood Flow Velocity
Sammanfattning : This thesis aims to evaluate the blood flow velocity in the Brachial artery during reactive hyperemia. Primarily to appraise the information it might contain regarding cardiovascular function and cardiovascular risk. LÄS MER
5. Optical frequency modulated continuous wave (FMCW) range and velocity measurements
Sammanfattning : By using a tunable laser diode and fiber components small compact ranging and radial velocity measuring systems can be realized utilizing a frequency modulating continuous wave (FMCW) technique. The thesis start with an introduction that explains some basic theory behind laser diodes, photodiodes and different optical measuring techniques. LÄS MER
