Rethinking Explanation

This volume is a product of the international research project Theory of Explanation,which was funded by the Joint Committee for Nordic Research Councils for the Humanities and the Social Sciences (NOS-HS). The project started in 2001 and operated for a period of three years by organizing a number of workshops on scientific explanation in Norway, Iceland, Sweden and Finland. The workshops included

Design and Performance of a Hybrid Ventilation System with Heat Recovery for Low Energy Buildings

A new hybrid ventilation system for low energy buildings has been investigated theoretically using TRNSYS. The system is based on natural ventilation but utilizes a fan during hours when the natural driving forces are not sufficient. Heat from the exhaust air is recovered in an air-to-water heat exchanger. The heated water is pumped to the incoming ventilation air where it is heat exchanged to pre

NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques

Popular Abstract in Swedish Avsikten med detta arbetet har varit att utveckla kärnmagnetisk resonans, NMR, tekniken, applicerat på gel-emulsioner. Gel-emulsioner är viktiga i många tekniska formuleringar så som i livsmedel, i kosmetika, i läkemedelsformuleringar och i sprängmedel för att nämna några applikationer. Vi har arbetat med en teknik som kallas NMR diffusometri, som utvecklats av StejskalThe aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications. We have worked with the NMR diffusom

”’Den kungliga skölden’ – Per Albin Hansson, Gustaf V och medierna 1940”

The chapter compares the media roles of the Swedish monarchy with that of the country's Labor Movement. In focus are the ways in which these two institutions used and were used in the visual culture of Sweden during World War Two. It is predominantly the official roles of king Gustaf V and prime minister Per-Albin Hansson that are under scrutiny, not least the common media platforms of these two i

Particle generation from humans - a method for experimental studie in cleanroom technology

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

Approximate distance oracles for geometric graphs

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.

Environmentally Friendly Disposal Behaviour and Local Support Systems: lessons from a metropolitan area.

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

Silent CMOS circuits aiming for system-on-chip

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

Mechanical embodiment design with digital desktops

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
