  2. 1. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

    Author : Svante Alfredsson; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Abstract : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. READ MORE

  5. 3. Wave Splitting in Direct and Inverse Scattering Problems

    Author : Mats Gustafsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maxwell equations; inverse problem; Electronics; inverse scattering; wave splitting; Elektronik;

    Abstract : The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. READ MORE

  6. 4. Photonic crystals and photocatalysis : Study of titania inverse opals

    Abstract : Due to an increase of human activity, an increase health risk has emerged from the presence of pollutants in the environment. In the transition to renewable and sustainable life style, treatment of pollutants could support the shifting societies. READ MORE

  7. 5. A Two-stage Numerical Procedure for an Inverse Scattering Problem

    Author : John Bondestam Malmberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coefficient inverse problem; inverse scattering; backscattering data; approximate global convergence; finite element method; adaptivity; a posteriori error analysis; a posteriori error analysis;

    Abstract : In this thesis we study a numerical procedure for the solution of the inverse problem of reconstructing location, shape and material properties (in particular refractive indices) of scatterers located in a known background medium. The data consist of time-resolved backscattered radar signals from a single source position. READ MORE
