    Author : Anders Andersson; Högskolan i Jönköping.; Växjö universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys; Schwarz–Christoffel mapping; rounded corners; tangent polygons; outer polygon; zipper algorithm; Mathematics; Matematik; Schwarz-Christoffel mapping; Schwarz-Christoffelavbildningen; rundade hörn; tangentpolygoner; yttre polygoner; zipper-algoritmer;

    Abstract : Inom många tillämpningar används konforma avbildningar för att transformera tvådimensionella områden till områden med enklare utseende. Ett exempel på ett sådant område är en kanal av varierande tjocklek begränsad av en kontinuerligt deriverbar kurva. READ MORE

  2. 2. Mathematical Tools Applied in Computational Electromagnetics for a Biomedical Application and Antenna Analysis

    University dissertation from Västerås : Mälardalen University

    Author : Farid Monsefi; Mälardalens högskola.; [2015]

    Abstract : To ensure a high level of safety and reliability of electronic/electric systems EMC (electromagnetic compatibility) tests together with computational techniques are used. In this thesis, mathematical modeling and computational electromagnetics are applied to mainly two case studies. READ MORE

  3. 3. Subspace Computations via Matrix Decompositions and Geometric Optimization

    University dissertation from Matematiska institutionen

    Author : Lennart Simonsson; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Numerical Analysis; Rank-revealing UTV; Jacobi-Davidson algorithm; Decomposition; Grassmann type algorithms; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Abstract : This thesis is concerned with the computation of certain subspaces connected to a given matrix, where the closely related problem of approximating the matrix with one of lower rank is given special attention.To determine the rank and obtain bases for fundamental subspaces such as the range and null space of a matrix, computing the singular value decomposition (SVD) is the standard method.

  4. 4. A numerical study of two-fluid models for dispersed two-phase flow

    University dissertation from Stockholm : KTH

    Author : Reynir Levi Gudmundsson; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; two-phase flow; two-fluid mode; well-posedness; numerical experiments; Numerisk analys; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Abstract : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. READ MORE

  5. 5. Singular Integral Equations: Applications to Elasticity and Numerical Solution

    University dissertation from Numerical Analysis, Lund University

    Author : Jonas Englund; Lunds universitet.; Lund University.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datalogi; numerisk analys; system; kontroll; fracture mechanics; second kind integral equation; Nyström scheme; Computer science; control; systems; numerical analysis;

    Abstract : The purpose of this thesis is to develop stable, accurate, and efficient numerical algorithms for the solution of certain problems in materials science using integral equations. All the appearing integral equations are of the second kind. Such equations are typically well suited for numerical solution. READ MORE
