Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. The focus is on a finite element procedure for modelling these dynamic properties of rubber in a way that is easy to ado
The aim of this study was to analyze how preschool principals talk about their obligation to report child maltreatment to social services. Five principals, from five different local areas, were interviewed in the study. Two of the preschools were situated in underprivileged areas, and the others in economically and socially fairly well situated areas. Discourse analysis was applied in the examinat
This article deals with Gunnar Rosendal within church politics in a European perspective. The term church politics is here used in a broad sense, referring to the church’s management of internal problems and conflicts as well as the political strategies of the church in its relation to state and society. In my study I focus on three fields that in various ways got church political consequences or This article deals with Gunnar Rosendal within church politics in a European perspective.

The bio-economy represents a significant shift in socio-economic, agricultural, energy and technical systems. The concept of the bio-economy – also called the bio-based economy or the knowledge-based bio-economy in Europe – can be understood as an economy where the basic building blocks for materials, chemicals and energy are derived from renewable biological resources, such as plant and animal so
Abstract in UndeterminedThe demands for energy efficent heating solutions for the manufacturing industry can be met by a new induction heating platform, presented in this article. A new concept and technology to design and manufacture induction heating units is explained, evaluated and tested with successful results. The so called Greenheat technology relies on inductors built on Litz wiring mould
The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.
In this thesis various topics in universal lossless source coding are discussed and analyzed. The main focus in this work is on lossless data compression of grayscale still images. Such images are, for example, frequently occurring in medical imaging. Based on theoretical considerations and empirical observations new compression algorithms are presented that are, in terms of compression performan
