  2. 21. On Importance Sampling and Dependence Modeling

    Author : Jens Svensson; Boualem Djehiche; Thomas Mikosch; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    Abstract : This thesis consists of four papers. In the first paper, Monte Carlo simulation for tail probabilities of heavy-tailed random walks is considered. Importance sampling algorithms are constructed by using mixtures of the original distribution with some other state-dependent distributions. READ MORE

  4. 22. Power Reactor Noise Studies and Applications

    Author : Vasiliy Arzhanov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; power spectra; control rod vibrations; Green s function; nesting hypothesis; adjoint function; fluctuating boundary; noise diagnostics; Accelerator Driven System; localisation algorithm; point reactor and adiabatic approximation;

    Abstract : The present thesis deals with the neutron noise arising in power reactor systems. Generally, it can be divided into two major parts: first, neutron noise diagnostics, or more specifically, novel methods and algorithms to monitor nuclear industrial reactors; and second, contributions to neutron noise theory as applied to power reactor systems.

  5. 23. Dynamics of high-angle grain boundary YBCO Josephson junctions

    Author : Tobias Lindström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes experimental investigations of properties of high-angle YBa2Cu3O7−δ(YBCO)bicrystal Josephson junctions and SQUIDs fabricated on SrTiO3-substrates. The main focus of theinvestigation has been on the effects of the predominant d-wave symmetry of the superconductingwavefunction in YBCO on transport properties and dynamics. READ MORE

  6. 24. The Doc, the Mock and the What? : Events of Realing, Mockumentalities and the Becoming-Political of the Viewing Subject

    Author : Miriam von Schantz; Göran Eriksson; Cecilia Mörner; Johan Nilsson; Malin Wahlberg; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mockumentary; reception study; method assemblage; spectatorial contract; Deleuze; Guattari; regime of truth; becoming-political;

    Abstract : This study aims at making inquiry into what happens when a viewing subject encounters a film where it proves difficult to recognize if it is factual or fictional. In order to meet this aim the dissertation offers an experimental approach of both theoretical and methodological nature. READ MORE

  7. 25. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE
