Geometrical Structure, Phase Diagrams, and Core-Level Binding Energiesof Metal Surfaces: Calculations, Simulations, and Experiments

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

Dynamic Optimization of Modelica Models -- Language Extensions and Tools

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

Fackliga organisationer och industrial relations

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

Studies on Laser Generated Vacuum Ultraviolet Radiation and Spectroscopic Investigations of Light Elements in Laser-Produced Plasmas

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
