    University dissertation from Department of Theoretical Physics, Lund University

    Author : Henrik Jönsson; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gravitation; statistical physics; relativity; annealing; variational; mean-field; phylogeny; constraint satisfaction; combinatorial optimization; maximum likelihood; Physics; Fysik; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2001:Jönsson; Matematisk och allmän teoretisk fysik; thermodynamics;

    Abstract : Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed.

    Abstract : Artificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. READ MORE

  4. 4. Synthesis and Characterisation of Ultra Thin Film Oxides for Energy Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mattis Fondell; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic Layer Deposition; Iron oxides; Hematite; Solar Water Splitting; Hard X-Ray Photoelectron Spectroscopy;

    Abstract : This thesis describes studies of materials which can be exploited for hydrogen production from water and sunlight. The materials investigated are maghemite (γ-Fe2O3), magnetite (Fe3O4) and especially hematite (α-Fe2O3), which is an iron oxide with most promising properties in this field. READ MORE
