Popular Abstract in Swedish Denna avhandling utgår från den betydande variationen i försäljning av antidepressiva läkemedel mellan olika geografiska områden. Allmänläkare förskriver cirka två tredjedelar av dessa läkemedel. Syftet med forskningsprojektet var dels att kartlägga allmänläkares uppfattningar om depression och faktorer som kan ha betydelse för deras sätt att behandla patienter med deprThis thesis emanates from considerations about the inter-regional variation of the sales of antidepressive drugs, and how general practitioners may contribute to that variation. The thesis comprises two data collections utilized for five separate studies. The first data set emerges from interviews with seventeen general practitioners and is used for papers I and II. The first paper reports on gene

Time-domain windowing of transmit blocks in multicarrier transmission is a technique frequently used to improve the properties of the transmit spectrum. An intersymbol window is longer than a multicarrier symbol including its cyclic extension. Before windowing, additional cyclic extensions at the beginning and at the end of each multicarrier symbol are introduced. Since the window only shapes thes

Popular Abstract in Swedish Det elektriska kraftsystemets uppgift är att ge konsumenter en säker och stabil energitillgång till lägsta möjliga kostnad. Sett ur ett ingenjörsperspektiv tillkommer några extra krav såsom att variationerna i spänning och frekvens skall vara acceptabla, samt att enstaka komponenters kapacitetsgränser ej överskrids. Om dessa krav ej uppfylls kan detta leda till leveransThis thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. The first part deals with the coordination of cascaded tap changers in radial distribution feeders. A tuning rule for the con

In this work, we report an original experimental approach for mapping the droplets Sauter Mean Diameter (SMD) of a hollow-cone water spray using the SLIPI-LIF/MIE technique. Water mixed with a non-toxic fluorescing dye is continuously injected at 20 bars injection pressure and the formed hollow-cone spray is illuminated using a continuous wave laser. The illumination wavelength is carefully chosen

A system for generating and detecting laser-produced radiation in the wavelength region below 200 nm has been constructed. The generation techniques are mainly based on nonlinear frequency mixing processes in gaseous media. Other techniques for the production of vacuum ultraviolet radiation, for instance the use of a laser-produced plasma, are briefly discussed. Laser-produced plasmas have also be

Popular Abstract in Swedish Avsikten med avhandlingen är att ge en bild av Hilding Rosenbergs musikverk "Johannes Uppenbarelse" (1940), för stor orkester, kör och recitation (recitativ), genom att belysa verkets tillkomsthistoria och grundläggande litterära och musikaliska struktur. Som en komposition som från början var avsedd att sändas ut över radion, bestämdes form och innehåll i "Johannes UppThe intention of this dissertation is to provide a portrait of Hilding Rosenberg´s musical work "The Revelation of S:t John" (1940), for a large orchestra, chorus and recitation (recitative), through illuminating the work´s history of origin and basic literary and musical structure. As a composition initially intended for broadcast over the radio, the form and content of "The Revelation of S:t Joh

High accuracy and low computational costs are essential properties for efficient finite element codes. Improvements of the finite element method in order to satisfy these qualities have been the subject for extensive research activities ever since its introduction. In this thesis, a class of improved low-order finite elements is proposed which possesses high accuracy in bending even for coarse

The chapter investigates the overlaps between diplomatic and masonic culture in London during the end of the eighteenth century.

This paper presents a review of and a comparison between two different methods to solve an inverse scattering problem in the time domain. The problem is that of propagation of transient electromagnetic waves in spatially inhomogeneous slabs of finite length. The permittivity and conductivity profiles are assumed to vary only with depth and the scattering problem is thus onedimensional. Several alg
