  2. 1. Insights into Materials Properties from Ab Initio Theory : Diffusion, Adsorption, Catalysis & Structure

    Author : Andreas Blomqvist; Rajeev Ahuja; Christopher Wolverton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Diffusion; Catalysis; Adsorption; Random structure search; Hydrogen-storage materials; Phase-change materials; Defects and diffusion; Defekter och diffusion; Surfaces and interfaces; Ytor och mellanytor; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis, density functional theory (DFT) calculations and DFT based ab initio molecular dynamics simulations have been employed in order to gain insights into materials properties like diffusion, adsorption, catalysis, and structure. In transition metals, absorbed hydrogen atoms self-trap due to localization of metal d-electrons. READ MORE

  4. 2. In search of a biosensor for DNT detection : Studies of inducer response and specificity of DntR

    Author : Rosa Lönneborg; Peter Brzezinski; Ray Dixon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DntR; transcriptional regulation; gfp; nitro-aromatic compounds; LysR family; LTTR; TNT; DNT; FACS; directed evolution; random mutagenesis; recombination; structure determination; biokemi; Biochemistry;

    Abstract : The primary aim of the work presented in this thesis was to change the inducer specificity of the DntR protein in order to improve the response to DNT. The long-term goal is to use this protein in a biosensor for DNT, a signature compound for detection of the explosive TNT. READ MORE

  5. 3. Efficient concurrent data structure access parallelism techniques for increasing scalability

    Author : Adones Rukundo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FIFO queue; parallelism; performance modelling; design framework; semantic relaxation; Data structure; multi-access; lock free; performance analysis; counter; concurrency; search tree.; stack; multi-core processor; priority queue;

    Abstract : Multi-core processors have revolutionised the way data structures are designed by bringing parallelism to mainstream computing. Key to exploiting hardware parallelism available in multi-core processors are concurrent data structures. READ MORE
