The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micr

Fast and reliable time and frequency synchronization is crucial for packet-based orthogonal frequency division multiplex (OFDM) systems. In this paper we compare and analyze preambles for OFDM systems based on repeated OFDM data symbols or repeated short pseudonoise sequences (PN-sequences). We make an analytical evaluation for AWGN channels and simulate the performance in oneand two-tap Rayleigh

I give an overview of the calculations done in three-flavour Chiral perturbation theory at next-to-next-to-leading order with an emphasis on those relevant for an improvement in the accuracy of the measurement of Vus. It is pointed out that all needed low energy constants can be obtained from experiment via the scalar form-factor in Kl3 decays

The clean development mechanism (CDM), outlined in Article 12 of the Kyoto Protocol (UNFCCC 1997) is one of the most debated and disputed provisions of the current climate regime. Developing and developed states, business as well as environmental NGOs all seem to be dissatisfied with the mechanism in its current shape, and a reform of the CDM is therefore high on the agenda of the climate negotiat

This article outlines a numerical study on the benefit of using High-Performance/Strength Concrete for fabrication of concrete elements. For this purpose a comparison is done between the cost of existing beams with normal strength concrete and optimized beams made of High-Performance/Strength Concrete. A background is given concerning the most essential properties of High-Performance/Strength Conc

Liturgical reform is rampant today. The liturgical movement of the twentieth century has been succeeded by a period of uninformed tinkering with the liturgy by individual priests and ministers. The article identifies and criticizes five possible reasons for reforming (or simply changing) the liturgy.

To promote industrial development and economic growth is a vital issue for governments all over the world. The ideals guiding policymakers in their endeavours, strongly influenced by traditional economics and the innovation system approach, are that innovations based on new and advanced knowledge are central for industrial and economic development. As is exemplified through the quote below policym

Hans Christian Andersen's tale "The Marsh King's Daughter" (1858) is analysed in relation to Birgitta Trotzig's prose tale of the same title, Dykungens dotter (1985), with the emphasis on Andersen's tale which would seem to be a pious Christian morality in which evil is destroyed and the powers of light conquer darkness. At the same time, Andersen's symbols make clear that darkness is a necessary

This thesis analyzes the electrical properties of InAs nano-structures, that are integrated into different materials and geometries. The thesis describes integration related issues of InAs, the epitaxial synthesis of the InAs nano-structures and summarizes experimental techniques for analysis of electrical properties of the integrated structures. InAs thin films, nanowires and membranes are invest

In this article I discuss the relationship between the victim’s and the perpetrator’s guilt in a rape situation. Does recognition of the victim’s guilt automatically remove (any) responsibility from the perpetrator? One way of arguing that is does is to lean on an expanded version of the principle that “ought implies can”, which implies that the magnitude of the difficulty involved in abstaining f

In this chapter, we first elaborate on the discussion of the nature of CKEs that has taken place in the previous chapters in the book. Secondly, we summarise the main lessons we have learnt about CKEs from the studies reported in this book. Thirdly, we identify and analyse what circumstances and conditions promote creativity in organisations and which ones hinder it. We also identify some of the m
