This thesis develops the methodology for solving initial boundary value problems with the use of summation-by-parts discretizations. The combination of high orders of accuracy and a systematic approach to construct provably stable boundary and interface procedures makes this methodology especially suitable for scientific computations with high demands on efficiency and robustness. Most classes ...

The purpose of this master's thesis was to explore the circuit design space (speed, area, power) of conventional binary arithmetic and to suggest improvements or alternatives to this arithmetic. The alternatives to the binary arithmetic focused on was the Signed-Digit (SD) number system, the Residue Number System (RNS) and the combination of these two systems (RNS+SD). The work resulted in new ...

I have done my master thesis project on autonomic computing at Amadeus, a major provider of online travel booking systems. Autonomic computing is an effort to decrease the cost of owning an IT infrastructure through self-management of systems. The approach is to develop an infrastructure for an external autonomic manager which can interact with legacy systems. This infrastructure is implemented...

The ideas of Benôıt Mandelbrot, about the geometrical properties of sets which he called fractal, was published as late as 1975. Since then, there have for fractals, and most commonly the estimation of the fractal dimension, been found uses in the most diverse applications. Fractal geometry has been used in information theory, economics, flow dynamics and image analysis, among many different ar...

Background. High numbers of incidents of abuse in health care (AHC) have been reported by patients in Sweden. In questionnaire studies (n=9600), every fifth Swedish woman and every tenth Swedish man reported any lifetime experience of AHC, and a majority reported suffering from their experiences. Female patients with experiences of AHC described them as experiences of being nullified, and male ...
