  1. 16. Fast Numerical Techniques for Electromagnetic Problems in Frequency Domain

    Författare :Martin Nilsson; Per Lötstedt; Abderrahmane Bendali; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fast Multipole Method; Minimal Residual Interpolation; Sparse Approximate Inverse preconditioning; Method of Moments; fast solvers; iterative methods; multiple right-hand sides; error analysis; Numerical Analysis; Numerisk analys;

    Sammanfattning : The Method of Moments is a numerical technique for solving electromagnetic problems with integral equations. The method discretizes a surface in three dimensions, which reduces the dimension of the problem with one. A drawback of the method is that it yields a dense system of linear equations. LÄS MER

  3. 17. Rektorers normer i ledarskapet för skolutveckling

    Författare :Helena Hallerström; Rättssociologiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social sciences; norm analyses; norm model; structures; norm supporting; norms; local authorities; law; decentralisation; steerage; principals´ domain; domain; principals´ norms; curriculum development; educational development; education; development; leadership; headmaster; Sociology of law; principal; Juridical science; Administrative law; Sociology; Samhällsvetenskaper; Rättsvetenskap; juridik; Förvaltningsrätt; Sociologi;

    Sammanfattning : This thesis puts a focus on school leadership and school development. The local authorities took over responsibility for public education in 1991. At the same time, steerage by rules was abandoned in favour of steerage by goal-setting and result evaluation. The principal is an important link in this chain of steerage. LÄS MER

  4. 18. The Weighted Space Odyssey

    Författare :Martin Křepela; Sorina Barza; Gord Sinnamon; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integral operators; supremal operators; weights; weighted function spaces; Lorentz spaces; Lebesgue spaces; convolution; Hardy inequality; multilinear operators; nonincreasing rearrangement; Matematik; Mathematics;

    Sammanfattning : The common topic of this thesis is boundedness of integral and supremal operators between weighted function spaces.The first type of results are characterizations of boundedness of a convolution-type operator between general weighted Lorentz spaces. LÄS MER

  5. 19. Homogenization of some elliptic equations with connections to elasticity

    Författare :Klas Pettersson; Patrizia Donato; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; Mathematics; Matematik;

    Sammanfattning : In this PhD thesis we prove some properties of elliptic equations in connection with periodic homogenization. We mainly study the stationary linearized elasticity system. This thesis consists of five papers complemented with a short introduction.The first paper concerns some elliptic equations on a domain with oscillating boundary. LÄS MER

  7. 20. Variational Tensor-Based Models for Image Diffusion in Non-Linear Domains

    Författare :Freddie Åström; Michael Felsberg; George Baravdish; Reiner Lenz; Christoph Schnörr; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; image diffusion; variational formulation; denoising; tensor; non-linear;

    Sammanfattning : This dissertation addresses the problem of adaptive image filtering.Although the topic has a long history in the image processing community, researchers continuously present novel methods to obtain ever better image restoration results. LÄS MER
