Quasi Resonant DC Link Converters - Analysis and Design for a battery Charger Application

Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. Active power line conditioning capabilities could be included in the ba

The Origins (or Evolution) of Organizational Capabilities

The purpose of this proposed symposium is to bring scholars together to discuss and debate the origins of organizational capabilities. The question of origins has been a sticky one to resolve, specifically due to the problem of infinite regress and the multi-level nature of capabilities. For example, should explanation of capabilities be reduced to, say, genes? What is the appropriate level of ana

A constructive algorithm for memory-aware task assignment and scheduling

This paper presents a constructive algorithm for memory-aware task assignment and scheduling, which is a part of the prototype system MATAS. The algorithm is well suited for image and video processing applications which have hard memory constraints as well as constraints on cost, execution time, and resource usage. Our algorithm takes into account code and data memory constraints together with the

A low-cost time-hopping impulse radio system for high data rate transmission

We present an efficient, low-cost implementation of time-hopping impulse radio that fulfills the spectral mask mandated by the FCC and is suitable for high-data-rate, short-range communications. Key features are (i) all-baseband implementation that obviates the need for passband components, (ii) symbol-rate (not chip rate) sampling, A/D conversion, and digital signal processing, (iii) fast acquisi

Simulation of indenter geometry effects in nanoindentation

The elastic-plastic behaviour as the response to indenter geometry, such as tip radius and angle, are simulated in the study. The hardness and the Young modulus of the material are determined combining both analytical and numerical methods and their dependence on the tip radius and angle is investigated.

Läsmaskinen. Aspekter på bild och bok med utgångspunkt i Anders Billows verksamhet 1923–1953

The title of this thesis is The Reading Machine. Aspects of Image and Book in the Works of Anders Billow 1923 – 1953. My aim is to revise and complement the historical understanding of the establishing of the modernistic “new typography” within the theory and practice of graphic design. A wider ambition is to, through example, better clarify the surrounding society’s influence on design and how ne
