  1. 1. Hybrid methods for computational electromagnetics in the frequency domain

    Författare :Stefan Hagdahl; KTH; []
    Nyckelord :Computational Electromagnetics; Hybrid Methods; Boundary Element Method; Geometrical Theory of Diffraction;

    Sammanfattning : In this thesis we study hybrid numerical methods to be usedin computational electromagnetics. We restrict the methods tospectral domain and scattering problems. The hybrids consist ofcombinations of Boundary Element Methods and Geometrical Theoryof Diffraction.In the thesis three hybrid methods will be presented. LÄS MER

  3. 2. Development of IT-supported Inter-organisational Collaboration : A Case Study in the Swedish Public Sector

    Författare :Anneli Hagdahl; Toomas Timpka; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information technology; Public sector; interorganizational relations; Interorganizational relations; labour market; Information technology; Informationsteknologi;

    Sammanfattning : Collaboration across the organisational boundaries takes place for different reasons. One of them is to solve complex problems that cannot be dealt with by a single organisation. The area of vocational rehabilitation constitutes an example of inter-organisational collaboration motivated by a need for joint problem solving. LÄS MER

  4. 3. Hybrid Methods for Computational Electromagnetics in Frequency Domain

    Författare :Stefan Hagdahl; Björn Engquist; Lars Pettersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; Geometrical Theory of Diffraction; Smooth Surface Diffraction; Boundary Element Method; Hybrid methods; Electromagnetic Scattering; Numerical analysis; Numerisk analys;

    Sammanfattning : In this thesis we study hybrid numerical methods to be used in computational electromagnetics. The purpose is to address a wide frequency range relative to a given geometry. We also focus on efficient and robust numerical algorithms for computing the so called Smooth Surface Diffraction predicted by Geometrical Theory of Diffraction (GTD). LÄS MER
