Particle generation from humans is a severe problem when working in cleanrooms and other controlled environments. Data regarding the number of particles generated by humans are few and there are no detailed references as to how these studies have been performed. An experimental method to determine the particle release from a human being in a cleanroom was developed and used to describe the variati
Given a geometric t-spanner graph G in Ed with n points and m edges, with edge lengths that lie within a polynomial (in n) factor of each other. Then, after O(m+n log n) preprocessing, we present an approximation scheme to answer (1+ε)-approximate shortest path queries in O(1) time. The data structure uses O(n log n) space.
The amount of household refuse has steadily increased in Sweden and this is consistent with the trend in the rest of the European Union. Strategies for household waste reduction includes sorting, recycling, re-use and repair. Two categories of motivational factors determine disposal behaviour, external and internal. The external factors include administrative, economic, information and physical me
The present contribution describes some simulations of the observation of binaries with GAIA. The results do not differ fundamentally from earlier estimates, e.g. in GAIA's Concepts and Technology Study Report (ESA-2000-SCI-4), but they are based on more realistic assumptions and much more extensive numerical work.
A silent CMOS circuit architecture is proposed. Different silent CMOS gate solutions are presented and compared to the normal CMOS precharged gate in switching noise level. A silent 16-bit parallel carry-look-ahead adder is demonstrated. Simulation results on the circuits and the post layout of the adder are given, which shows a 10 times reduction in noise level is possible

Abstract in French Cette contribution décrit l’aide potentielle que le concept de table interactive apporte à certaines tâches du concepteur en mécanique. Le travail de recherche présenté n’en est qu’à sa genèse. La problématique est la suivante : une fois la faisabilité d’une idée de produit (le concept) est prouvée, le concepteur développe l’architecture et les composants du produit (embodiment This paper describes the potential help that the interactive desktop concept can bring to the execution of embodiment design tasks. The presented project is still in its infancy. The research framework is the following: once a product concept has been approved, the mechanical design engineer develops the product architecture and product part (also called embodiment design). Sketches at that level
This book chapter discusses gender and sexuality in contemporary Scandinavian stagings of Henrik Ibsen's plays, with a special focus on the characters Nora (The Doll's House) and Hedda (Hedda Gabler).
Under hösten 2008 inledde Region Skånes kulturnämnd arbetet med att ta fram nya regler och en ny modell för bidragsgivning och uppdragsöverenskommelser med studieförbunden i Skåne. Det nya regelverket var delvis en konsekvens av den kritik rörande ”otydlig politisk styrning” som Region Skånes revisorer under 2007 riktat mot Regionens sätt att hantera sina bidrag till studieförbunden.1 Det nya rege
The theoretical findings of the thesis is composed of three parts, it consists of (i) a framework for social entrepreneurship, (ii) some pitfalls and success factors and (iii) a perspicuous design guide. These findings was a result of field research during a long time – more than 5 years, 2000-2005 – and the scientific purpose was to give a broad description and understanding of the research probl
