  1. 1. Rigorous Simulation Its Theory and Applications

    Författare :Adam Duracz; Walid Taha; Veronica Gaspes; Kazunori Ueda; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulation; verification; interval analysis; validated numerics; hybrid systems; cyber-physical systems;

    Sammanfattning : Designing Cyber-Physical Systems is hard. Physical testing can be slow, expensive and dangerous. Furthermore computational components make testing all possible behavior unfeasible. Model-based design mitigates these issues by making it possible to iterate over a design much faster. LÄS MER

  2. 2. Heat and Mass Transfer in Built Structures - Numerical Analyses

    Författare :Jinkai Wang; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air convection; heat; numerical procedure; air and moisture transport; long-term thermal performance; numerical stability; gas-filled foam; thermal aging; simulation;

    Sammanfattning : Heat and mass transport processes are often present simultaneously in built structures in building applications. The emphasis of this thesis is to contribute to knowledge about predicting the effects of combined heat and mass transport in built structures. LÄS MER

  3. 3. Numerical Simulation of High Reynolds Number Wall Bounded Flow

    Författare :Tobias Persson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subgrid model; DES; high; validation; LES; numerical simulation; near-wall;

    Sammanfattning : In this thesis, four different numerical methods are used for predictions of high Reynoldsnumber (Re), wall bounded flows; Large Eddy Simulation (LES) with two different subgrid(turbulence) models, the One Equation Eddy Viscosity model (OEEVM) and the MixedModel (MM), Monotone Integrated LES (MILES), Detached Eddy Simulation (DES) andReynolds Averaged Navier Stokes (RANS). The LES calculations are combined with a wallmodel based on the law-of-the-wall and in DES a hybrid RANS/LES method is used forhandling the near wall region. LÄS MER

  4. 4. Visualization and mesoscopic simulation in systems biology

    Detta är en avhandling från Stuttgart : OPUS University of Stuttgart

    Författare :Martin Falk; Thomas Ertl; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Visualization; GPGPU; Simulation; Systems Biology; Model Development; Signal Transduction;

    Sammanfattning : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. LÄS MER

  5. 5. Numerical simulation of tube hydroforming adaptive loading paths

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Joakim Lundqvist; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The tube hydroforming process is still to be considered a new and advanced technique. The process has been adopted into several industries, e.g. automotive and aero. LÄS MER
