1. Fuel Optimal Powertrain Control for Heavy Trucks Utilizing Look Ahead
Sammanfattning : The road topography in highways affects the powertrain control of a heavy truck substantially since the engine power is low in relation to the vehicle weight. In large road gradients constant speed is not possible to keep, which would have been beneficial otherwise, and in some uphills shifting gears becomes inevitable. LÄS MER
2. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training
Sammanfattning : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. LÄS MER
3. Haptic Milling Simulation in Six Degrees-of-Freedom : With Application to Surgery in Stiff Tissue
Sammanfattning : The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. LÄS MER
4. An Ontological Approach to support Knowledge Sharing between Product Design and Assembly Process Planning (APP)
Sammanfattning : Modern manufacturing organizations have to cope with several critical issues arising from the need for mass customization such as short product life-cycles, an increasing number of product variants and frequently changing customer requirements. One of the main factors that could aid overcoming those challenges is the use of information and communication technology (ICT) applications over a collaborative manufacturing environment, in which all stakeholders share and exchange knowledge across different manufacturing domains and applications.

5. 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
