  1. 11. Estimation of the Elastic Moduli of Porous Materials using Analytical Methods, Numerical Methods, and Image Analysis

    Författare :Thushan Chandrasiri Ekneligoda; Robert W. Zimmerman; Igor Tsukrov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : The effective bulk modulus and effective shear modulus of porous materials having various types of pore shapes are investigated, using both analytical and numerical methods. These solutions, and the scaling laws that are derived with the aid of these solutions, are then used to make predictions of the effective elastic moduli of some sandstones and ceramics, based on two-dimensional images of the pore space.

  4. 13. Linear statistics of random matrices and log-gases

    Författare :Klara Courteaut; Kurt Johansson; Christian Webb; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This thesis is concerned with point processes arising in Random Matrix Theory. It is a compilation thesis: it consists of an introduction and three research papers.In Paper A and Paper B, we study random matrices from the classical compact groups, namely orthogonal, unitary, and symplectic matrices distributed according to Haar measure.

  5. 14. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

    Författare :Robert Lewén; KTH; []
    Nyckelord :Optical communication; Fiber optic; Electroabsorption modulators; p-i-n photodiodes; transmission line; traveling wave; high-speed; microwave photonics;

    Sammanfattning : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. LÄS MER

  7. 15. Numerical methods for inverse heat conduction problems

    Författare :Fredrik Berntsson; Per Christian Hansen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ill-posed; Heat Conduction; Regularization; MATHEMATICS; MATEMATIK;

    Sammanfattning : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. LÄS MER
