1. Surfaces Designed for High and Low Friction
Abstract : This thesis comprises tribological studies of extremely well-defined surfaces of different designs. Both low-friction and high-friction surfaces were manufactured and experimentally evaluated.In the low-friction studies, lithography and anisotropic etching of silicon was first used as a texturing technique.

3. Tactile Perception - Role of Physical Properties
Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE

4. Optical Measurements of Rolling Friction Coefficients
Abstract : This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. READ MORE
