1. Controlled axonal outgrowth and cell reactions to nanostructures
Sammanfattning : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. LÄS MER
2. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact
Sammanfattning : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. LÄS MER
3. A TEM Investigation of Contact between Nanoparticles
Sammanfattning : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. LÄS MER
4. Towards the enhanced applicability of cold mix asphalt: : An experimental study focusing on surface free energies and the breaking and coalescence of bitumen emulsions
Sammanfattning : The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the road-engineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. LÄS MER
5. Optimization-based robot grasp synthesis and motion control
Sammanfattning : This thesis investigates the questions of where to grasp and how to grasp a given object with an articulated robotic grasping device. To this end, aspects of grasp synthesis and hand motion planning and control are investigated. LÄS MER
