Popular Abstract in Swedish Jag har i den här avhandlingen behandlat problemställningar inom tre olika områden inom astronomin. Det som sammanlänkar dessa är att alla innefattar dubbelstjärnor där avståndet mellan stjärnorna är litet, dvs de har en kort period. De är också alla datorsimuleringar. Jag har satt upp en modell för att betrakta de astronomiska systemen och genom numeriska metoder beräkThis thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. By using population synthesis models for binaries the probabilities for eclipses are calculated for diff

En redogörelse för och diskussion av debattklimatet (olika positioner) i Saudiarabien mot bakgrund av terrorvågen i början av 2000-talet.

In this paper, the history of IE languages is studied in terms of alignment change. What is significant in this change is the emergence of transitivity as a basic grammatical operational system. However, there are varying degrees of transition to transitivity-based system, especially between semantic and syntactic transitivity. It is argued that these degrees of transition create differences in gr

Narratological studies have quite frequently focused upon linguistic structures, considered to be paradigmatic cases of narrativity, whereas pictorial signs (such as icons and symbols) or indices have received comparably much less attention. In this paper, however, I intend to outline some basic and regularly occurring narrative aspects of pictures and non-pictorial objects. As a point of departu

Energianvändningen inom sektorn bostäder och service var år 2005 totalt 145TWh, vilket motsvarar 36 % av den slutliga energianvändningen i landet. Större andelen, 87 %, av energin används i bostäder och lokaler för uppvärmning, varmvatten och drift av apparater och installationer. Enbart uppvärmning och varmvatten svarar för 60 % av den energiförbrukningen och resten av energiförbrukningen går til

Analysis of the Swedish film "Nattens ljus" (Lars-Eric Kjellgren 1957)

The primary aim of the research project is to analyse the potential for the application of lidar and fluorescence techniques in building investigation, and also to establish a scientific remote-sensing method for surveying and analysing the historical facade that is non-destructive and can be used in-situ. The fluorescence lidar method uses point-monitoring and scanning of areas that can provide m

‘Transition’ was a concept used to denote that the former communist states in Europe were on the track towards establishment of a market economy in the wake of the collapsed planned economy. Another connotation of the concept was democracy – or democratisation – and a third, which was introduced when it became obvious that institutions were important for the transition to succeed, the Rechtsstaat,

We have realised a new technology for the integration of VFETs and RTDs. For these tunnelling transistors (so called resonant tunnelling permeable base transistors) we have developed large signal models which have been implemented in a Cadence simulation environment. The DC I-V characteristics are reproduced to a very high degree in these models. The models are further used for simulations of the

För bebyggelse, infrastruktur och bevarande finns lagar för tvångsvis åtkomst till mark. De fastighetsrättsliga ersättningsreglerna ger inte bara grunden för ersättningarna vid den tvångsvisa markåtkomsten utan sätter framförallt ramarna för de frivilliga situationerna. Vad ger ersättning och vad ger inte ersättning? Det finns många olika metoder och normer inom området och dessutom skiljer man på
