1. Technical and contractual aspects in winter highway and railway operation and maintenance : a survey of current technical systems and contract forms in Sweden
Sammanfattning : .... LÄS MER
2. Studies of Nanowire Friction using AFM-based Manipulation
Sammanfattning : In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length.

3. On the stability and control of piecewise-smooth dynamical systems with impacts and friction
Sammanfattning : This thesis concerns the analysis of dynamical systems suitable to be modelled by piecewise-smooth differential equations. In such systems the continuous-in-time dynamics is interrupted by discrete-in-time jumps in the state or governing equations of motion. LÄS MER
4. Existence theorems for noncoercive incremental contact problems with Coulomb friction
Sammanfattning : Friction is a phenomenon which is present in most mechanical devices and frequently encountered in everyday life. In particular, understanding of this phenomenon is important in the modelling of contact between an elastic object and an obstacle. LÄS MER
5. Microengineered CVD Diamond Surfaces : Tribology and Applications
Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER
