  2. 1. Numerical Complexity Analysis of Weak Approximation of Stochastic Differential Equations

    Author : Raul Tempone Olariaga; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adaptive methods; a posteriori error estimates; stochastic differential equations; weak approximation; Monte Carlo methods; Malliavin Calculus; HJM model; option price; bond market; stochastic elliptic equation; Karhunen-Loeve expansion; numerical co; Numerical analysis; Numerisk analys;

    Abstract : The thesis consists of four papers on numerical complexityanalysis of weak approximation of ordinary and partialstochastic differential equations, including illustrativenumerical examples. Here by numerical complexity we mean thecomputational work needed by a numerical method to solve aproblem with a given accuracy. READ MORE

  4. 2. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

    Author : Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

    Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. READ MORE

  5. 3. Experimental and numerical studies of thermal radiation in gas, coal and co-fired pilot test facilities

    Author : Adrian Gunnarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; soot volume fraction; Radiative heat transfer; co-firing;

    Abstract : Throughout the industrialized era, fossil fuels have been used extensively in combustion processes to generate heat and electricity. However, the combustion of such fuels creates emissions of greenhouse gases, mainly carbon dioxide, and other hazardous products. READ MORE

  6. 4. Co-rotational beam elements in instability problems

    Author : Jean-Marc Battini; KTH; []
    Keywords : instability; co-rotational mehtod; branch-switching; beam element; warping; plastic buckling. post-bifurcation; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. READ MORE

  7. 5. On Numerical Descriptions of Road Transport Missions

    Author : Pär Pettersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; Transport mission description; CO$_2$-emission; full vehicle simulation; road format; energy consumption; operating cycle;

    Abstract : This thesis addresses some issues of current interest in energy consumption prediction through simulation. First, we review the situation for rating, regulation and legislation of CO$_2$-emissions for cars and heavy vehicles. READ MORE
