  2. 1. Effective Distribution Theory

    Author : Fredrik Dahlgren; Viggo Stoltenberg-Hansen; Dag Normann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computable mathematics; computable analysis; domain theory; domain representations; distribution theory.; Mathematical logic; Matematisk logik;

    Abstract : In this thesis we introduce and study a notion of effectivity (or computability) for test functions and for distributions. This is done using the theory of effective (Scott-Ershov) domains and effective domain representations. READ MORE

  4. 2. Relational Networks and Family Firm Capital Structure in Thailand : Theory and Practice

    Author : Suranai Chuairuang; Barbara Cornelius; Håkan Boter; Anura De Zoysa; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Networks; relationships; capital structure decisions; family firm; small firm; information asymmetry; pecking order hypothesis; företagsekonomi; Business Studies;

    Abstract : Firms must access capital to remain in business.  Small firms have greater difficulty accessing financial resources than have large firms because of their limited access to capital markets.  These difficulties are exacerbated by information asymmetries between a small firm’ s management and capital providers.

  5. 3. 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

  6. 4. Limit Laws, Homogenizable Structures and Their Connections

    Author : Ove Ahlman; Vera Koponen; Dugald Macpherson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Model theory; random structure; finite model theory; simple theory; homogeneous structure; countably categorical; 0-1 law; Mathematical Logic; Matematisk logik; Mathematics; Matematik;

    Abstract : This thesis is in the field of mathematical logic and especially model theory. The thesis contain six papers where the common theme is the Rado graph R. Some of the interesting abstract properties of R are that it is simple, homogeneous (and thus countably categorical), has SU-rank 1 and trivial dependence. READ MORE

  7. 5. Formation stability and electronic structure of surfaces and interfaces from first principles

    Author : Jochen Rohrer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; band structure; van der Waals interaction; electronic structure; graphane; graphene; atomic structure; growth; thin film; interface; density functional theory; CVD; Alumina; nucleation;

    Abstract : This thesis deals with two closely interwoven aspects of first-principle(density functional theory) materials modeling:(1)~prediction of atomic structure & chemical composition,and (2)~prediction of electronic properties.In the first part, we focus on atomic structure (AS) and chemical composition (CC) of surface and interface systems.
