1. Design and analysis of a novel low loss homopolar electrodynamic bearing
Abstract : A novel homopolar electrodynamic bearing, together with a suitable permanent magnet drive, have been developed for high-speed applications where low losses and high reliability are essential and exclude the use of ball bearings, and yet where active magnetic bearings offer a too complex system solution. Considered applications are small turbomolecular vacuum pumps, and maintenance free flywheels for energy storage in remote telecom and satellite systems. READ MORE

2. Trends in Childbearing and Nuptiality in Sweden : A Period Analysis
Abstract : One purpose of this thesis is to introduce a system for presenting trends in family dynamics in contemporary Sweden. We use annual indexes of birth rates in order to display trends in childbearing for Swedish women over the years since 1961. We use similar annual indexes of marriage risks and divorce risks to display nuptiality trends since 1971. READ MORE

3. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder
Abstract : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. READ MORE

4. Wavelet and gabor frames and bases : approximation, sampling and applications
Abstract : This thesis is devoted to both theoretical and practical aspects of applied mathematics. It consists of three main parts: Part I consists of an application-oriented introduction to the theory of frames and bases for separable Hilbert spaces, as well as an introduction to the main tools used in the remaining Chapters: Time-frequency analysis, Gabor frames and wavelet frames.

5. Homogenization of Reynolds equations
Abstract : This Licentiate thesis is focussed on some new questions in homogenization theory, which have been motivated by some concrete problems in tribology. From the mathematical point of view, these questions are equipped with scales of Reynolds equations with rapidly oscillating coefficients. READ MORE
