1. Noise in quantum point contacts
Sammanfattning : .... LÄS MER
2. Spin transfer torques and spin dynamics in point contacts and spin-flop tunnel junctions
Sammanfattning : The first part of this thesis is an experimental study of the spin-dependent transport in magnetic point contacts. Nano-contacts are produced micromechanically, by bringing a sharpened non-magnetic (N) tip into contact with a ferromagnetic (F) film. LÄS MER
3. Powerful tool for analysis of systems containing traction point contacts
Sammanfattning : .... LÄS MER
4. Friction and wear in rolling and sliding contacts
Sammanfattning : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. LÄS MER
5. Extended Computational Module for Tractive Effort at Rolling and Spinning Point Contacts
Sammanfattning : One category of mechanical systems that contains power-transferring point contacts is traction drive variators. These variators can be used in different concepts for Continuously Variable Transmissions (CVTs) and in vehicle applications, in order to achieve optimum engine operating conditions leading to improved driveability, reduced fuel consumption and an increase in overall vehicle performance.
