  2. 11. Robust and Efficient Cell-Based Models of Tissue Mechanics

    Author : Sonja Mathias; Andreas Hellander; Ruth Baker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell-based model; numerical methods; time integration; adaptivity; GPU acceleration; cell mechanics; embryonic development; cartilage formation; Beräkningsvetenskap; Scientific Computing;

    Abstract : Cell-based models of tissue mechanics have become an important tool in cancer research and developmental biology. Complementary to wet-lab experiments, they allow for cost-efficient in-silico evaluation of mechanisms not easily probed in the lab. READ MORE

  4. 12. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics

    Author : Emil Kieri; Sverker Holmgren; Vasile Gradinaru; Hans O. Karlsson; Tobias Jahnke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computational wave propagation; quantum dynamics; time-dependent Schrödinger equation; spectral methods; Gaussian beams; splitting methods; low-rank approximation; Scientific Computing; Beräkningsvetenskap;

    Abstract : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. READ MORE

  5. 13. Modeling of Inelastic Response of Metals with Emphasis on Cyclic Viscoplasticity

    Author : Magnus Ekh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large strains; integration; anisotropy; plasticity; creep; viscoplasticity; kinematic hardening; metals; damage; calibration;

    Abstract : This thesis is concerned with the continuum modeling of the macroscopic behavior of engineering metals, in particular as part of life prediction strategies. Focus is primarily placed on the formulation and numerics of models for cyclic rate-dependent response. READ MORE

  6. 14. Pricing of Some Path-Dependent Options on Equities and Commodities

    Author : Mats Kjaer; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cliquet options with global floor; Commodity swing options; Storage valuation; Correlation matrix modelling; Bachelier-Samuelson model; Jump-diffusion models; Futures curve models; Parabolic PDE PIDEs; Numerical integration; Finite difference methods.;

    Abstract : This thesis brings together three papers about the pricing of European and Bermudan path-dependent options, and one paper about the stochastic modelling of a futures price curve. Paper one proposes a fast numerical method to compute the price of so called cliquet options with global floor, when the underlying asset follows the Bachelier-Samuelson model. READ MORE

  7. 15. Techniques to Calculate Exact Inclusion Probabilities for Conditional Poisson Sampling and Pareto .pi.ps Sampling Designs

    Author : Nibia Aires; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sampling theory; conditional Poisson sampling; Pareto pips sampling; order sampling; numerical integration; algorithms; sampling theory;

    Abstract : This thesis consists of five papers and treats two finite population sampling methods, viz. the Conditional Poisson and the Pareto .pi.ps sampling schemes. READ MORE
