Popular Abstract in Swedish Många fysiska egenskaper för ett material beror på den atomära strukturen, det vill säga vilka atomer som sitter var. För att bestämma den geometriska strukturen måste ofta en kombination av flera metoder användas. I detta arbete har vi använt högupplöst fotoelektronspektroskopi (HRCLS), diffraktion av lågenergetiska elektroner (LEED) samt beräkningar baserade på tätheThis thesis concerns clean and adsorbate covered metal surfaces and surface alloys. These systems have been studied using theoretical and experimental methods. In the first part of the thesis, the different techniques that have been utilized in this work are presented, and the included publications are summarized. The second part of the thesis consists of seven original publications. In the first

The Modelica language is currently gaining increased interest, both in industry and in academia. Modelica is an object-oriented, general purpose modeling language, targeted at modeling of complex physical systems. While the main usage of models developed in Modelica is simulation, several other usages emerge. Examples of such usages are dynamic optimization, model reduction, calibration, verificat

De fackliga organisationerna tillhör de viktigaste aktörerna på den svenska arbetsmarknaden. Jämfört med i många andra länder har den svenska fackföreningsrörelsen uppnått mycket av vad man eftersträvat. Det har säkerligen bidragit till att Sverige, tillsammans med Danmark och Finland, har världsrekord i facklig anslutning. Tillsammans med övriga nordiska länder är Sverige vidare unikt genom att d

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
