  1. 1. Analysis of adhesively bonded joints : an asymptotic approach

    University dissertation from Linköping : Linköpings Universitet

    Author : Peter Schmidt; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive Joints; Asymptotic Expansion; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Abstract : Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of using adhesive bonding, there is an increasing need for effective and accurate computational methods. READ MORE

  2. 2. Mobile Satellite Broadcast and Multichannel Communications analysis and design

    University dissertation from Stockholm : KTH

    Author : Cristoff Martin; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. READ MORE

  3. 3. The Dirac Equation: Numerical and Asymptotic Analysis

    University dissertation from Stockholm : KTH

    Author : Hasan Almanasreh; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dirac operator; eigenvalue problem; finite element method; spurious eigenvalues; Petrov-Galerkin; cubic Hermite basis functions; stability parameter; meshfree method; $hp$-cloud; intrinsic enrichment; G-convergence; $ Gamma$-convergence; scattering theory; identification; wave operator; stationary approach;

    Abstract : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. READ MORE

  4. 4. Simple Layer Potentials on Lipschitz Surfaces: An Asymptotic Approach

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johan Thim; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Singular integrals; Lipschitz surfaces; MATHEMATICS Algebra; geometry and mathematical analysis Mathematical analysis; MATEMATIK Algebra; geometri och analys Analys;

    Abstract : This work is devoted to the equationwhere S is the graph of a Lipschitz function φ on RN with small Lipschitz constant, and dS is the Euclidian surface measure. The integral in the left-hand side is referred to as a simple layer potential and f is a given function. READ MORE

  5. 5. Electromagnetic Dispersion Modeling and Analysis for Power Cables

    University dissertation from Växjö : Linnaeus University Press

    Author : Stefan Gustafsson; Linnéuniversitetet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; power cable; electromagnetic model; dispersion relation; asymptotic analysis; sensitivity analysis;

    Abstract : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. READ MORE
