  2. 26. Variance reduction methods for numerical solution of plasma kinetic diffusion

    Author : Lars Josef Höök; Torbjörn Hellsten; Thomas Johnson; Lars-Göran Ericsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; variance reduction; Monte Carlo; quasi-Monte Carlo; kinetic diffusion; stochastic differential equation;

    Abstract : Performing detailed simulations of plasma kinetic diffusion is a challenging task and currently requires the largest computational facilities in the world. The reason for this is that, the physics in a confined heated plasma occur on a broad range of temporal and spatial scales. READ MORE

  4. 27. Approximating Stochastic Partial Differential Equations with Finite Elements: Computation and Analysis

    Author : Andreas Petersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lévy process; Lyapunov equation; white noise; finite element method; multilevel Monte Carlo; Monte Carlo; multiplicative noise; asymptotic mean square stability; stochastic heat equation; covariance operator; weak convergence; generalized Wiener process; numerical approximation; stochastic wave equation; Stochastic partial differential equations;

    Abstract : Stochastic partial differential equations (SPDE) must be approximated in space and time to allow for the simulation of their solutions. In this thesis fully discrete approximations of such equations are considered, with an emphasis on finite element methods combined with rational semigroup approximations. READ MORE

  5. 28. Theoretical Studies Using Simple Ionic Liquid Models

    Author : Hongduo Lu; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Room Temperature Ionic Liquids; Coarse-Grained Models; Differential Capacitance; Monte Carlo; Classical Density Functional Theory; Room Temprerature Ionic Luqids; coarse-grained model; differential capacitance; Monte Carlo simulation; Classical Density Functional Theory;

    Abstract : Room Temperature Ionic Liquids (RTILs) are organic salts that melt below 100 degrees Celsius. The advantages of RTILs, such as high ionic concentrations and low melting points, promote several potential applications. For instance, RTILs could be utilized in manufacturing energy storage devices, and as efficient solvents. READ MORE

  6. 29. Monte Carlo approach to binding and aggregation of disordered peptides

    Author : Iskra Staneva; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; peptide binding; protein aggregation; Fysicumarkivet A:2012:Staneva;

    Abstract : In this thesis, theoretical models are applied to study some aspects of intrinsically disordered proteins, i.e. proteins that partly or entirely lack a stable native structure. In particular, focus is on peptide binding and aggregation. READ MORE

  7. 30. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study

    Author : Dogan Ergun Oner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide nucleation and growth; dissociative adsorption; metal oxidation; Monte Carlo simulations; Al 111 ; kinetics; aluminium; surface oxidation;

    Abstract : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. READ MORE
