  1. 1. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

    Author : Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

    Abstract : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. READ MORE

  2. 2. Computational Insights on Functional Materials for Clean Energy Storage : Modeling, Structure and Thermodynamics

    Author : Tanveer Hussain; Rajeev Ahuja; Caetano R. Miranda; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Hydrogen storage; Chemisorption; Physisorption; Functionalization; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The exponential increase in the demands of world’s energy and the devastating effects of current fossil fuels based sources has forced us to reduce our dependence on the current sources as well as finding cleaner, cheaper and renewable alternates. Being abundant, efficient and renewable, hydrogen can be opted as the best possible replacement of the diminishing and harmful fossil fuels. READ MORE

  3. 3. Modeling colloidal nanoparticles: From growth to deposition

    Author : Joakim Löfgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gold; DLVO; thermodynamics; van der Waals; density functional theory; modeling; deposition; dispersive interactions; anisotropic; colloidal nanoparticles; nanorods;

    Abstract : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. READ MORE

  4. 4. Modeling DNA Damage

    Author : Patric Schyman; Aatto Laaksonen; Sason Shaik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA; Ionizing radiation; DNA radicals; Strand break; Hydrogen abstraction; Density Functional Theory; Car-Parrinello Molecular Dynamics; QM MM; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : In this thesis methods of computational chemistry have been used to examine DNA damaging processes initiated by ionizing radiation, free radicals, or Low-Energy Electrons (LEE). The computational chemistry method based on quantum mechanics that has been mainly used here is the Density Functional Theory (DFT). READ MORE

  5. 5. Microkinetic Modeling of Nanoparticle Catalysis using Density Functional Theory

    Author : Mikkel Jørgensen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Density Functional Theory; Methane oxidation; Mean-field approximation; Microkinetic modeling; Kinetic Monte Carlo; Nanoparticles; Entropy; CO oxidation; Catalysis;

    Abstract : Heterogeneous catalysis is vitally important to modern society, and one path towardsrational catalyst design is through atomistic scale understanding. The atomistic scalecan be linked to macroscopic observables by microkinetic models based on first-principlescalculations. READ MORE
