  1. 1. Computational electromagnetics software development and high frequency modeling of surface currents on perfect conductors

    Detta är en avhandling från Stockholm : KTH

    Författare :Sandy Sefi; KTH.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High frequency approximations; Maxwell’s equations; Method of Moments; Physical Optics; Geometrical Theory of Diffraction; Extraction Extrapolation; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Sammanfattning : In high frequency computational electromagnetics, rigorous numerical methods be come unrealistic tools due to computational demand increasing with the frequency. Instead approximations to the solutions of the Maxwell equations can be employed to evaluate th electromagnetic fields. LÄS MER

  2. 2. Computational Terminology Exploring Bilingual and Monolingual Term Extraction

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jody Foo; Linköpings universitet.; Linköpings universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; terminology; automatic term extraction; automatic term recognition; computational terminology; terminology management;

    Sammanfattning : Terminologies are becoming more important to modern day society as technology and science continue to grow at an accelerating rate in a globalized environment. Agreeing upon which terms should be used to represent which concepts and how those terms should be translated into different languages is important if we wish to be able to communicate with as little confusion and misunderstandings as possible.

  3. 3. Computational Modeling of Complex Flows

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Johan Hoffman; Göteborgs universitet.; Gothenburg University.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computational fluid dynamics; adaptive finite element method; a posteriori error estimate; subgrid modeling; transition to turbulence; multiresolution analysis; object-oriented software;

    Sammanfattning : In this thesis we consider the following aspects of computational modeling of complex flows: (i) subgrid modeling, (ii) stability, (iii) a posteriori error estimation, and (iv) computational platform. <p />We develop a framework for adaptivity and error control for multiscale problems, in particular for turbulent flow, based on a posteriori error estimates.

  4. 4. Automated Computational Modeling

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Johan Jansson; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-adaptivity; Galerkin; ODE; PDE; plasticity; elasticity; FEM; automated;

    Sammanfattning : This thesis is part of the FEniCS project of Automation of Computational Mathematical Modeling (ACMM) as the modern manifestation of the basic principle of science:formulating mathematical equations (modeling) and solving equations (computation). The vision of FEniCS is to set a new standard towards the goals of generality, efficiency, and simplicity, concerning mathematical methodology, implementation, and application. LÄS MER

  5. 5. Computational methods for microfluidics

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ludvig af Klinteberg; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. LÄS MER
