  4. 17. MaMiS : A Programming Environment for Numeric/Symbolic Data Processing

    Author : Peter A. J. Nagy; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheme; MATLAB; MACSYMA; Numeric symbolic data processing;

    Abstract : This thesis describes a programming environment (called MaMiS - MATLAB and MACSYMA in Scheme) for symbolic/numeric data processing. This programming environment is based on three main parts:Scheme, a symbol manipulating language (a LISP dialect)MATLAB, a program for numeric scientific calculationsMACSYMA, a program for formula manipulationsA fourth part is added to MaMiS, the text editor DNU Emacs, which is used as an interface between the user and Scheme.

  5. 18. On finite element schemes for Vlasov-Maxwell system and Schrödinger equation

    Author : Christoffer Standar; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Schrödinger equation; Nitsche scheme; Streamline diffusion; Vlasov-Maxwell; a posteriori error analysis; a priori error analysis; hp-scheme; a posteriori error analysis;

    Abstract : This thesis treats finite element schemes for two kind of problems, the Valsov-Maxwellsystem and the nonlinear Schrödinger equation. We study streamline diffusion schemes applied for numerical solution of the one and one-half dimensional relativistic Vlasov-Maxwell system. The study is made both in a priori and a posteriori settings. READ MORE

  6. 19. Transonic flow: large eddy simulation, numerical methods and subgrid modeling

    Author : Christian Wollblad; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; SGS modeling; Transonic flow; semi-implicit numerical scheme; shock wave turbulent boundary layer interaction;

    Abstract : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. READ MORE

  7. 20. Theoretical Investigation into Longitudinal Dispersion in Natural Rivers — A Scaling Dispersion Model

    Author : Zhi-Qiang Deng; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; offshore technology; hydraulic engineering; Civil engineering; Scaling dispersion.; Parameter estimation; Numerical scheme; Dispersion coefficient; Natural river;

    Abstract : Using a broad variety of scientific methods this dissertation systematically investigates the fundamental mechanisms underlying the dispersion processes in natural rivers and their mathematical descriptions in a geometrical framework. Emphasis is on the geometrical variations and irregularities of a natural river and their scales. READ MORE
