  2. 1. Annealing of Cu2ZnSn(S,Se)4 Thin Films : A Study of Secondary Compounds and Their Effects on Solar Cells

    Author : Yi Ren; Charlotte Platzer-Björkman; Maarja Grossberg; Uppsala universitet; []
    Keywords : Annealing; sputtering; thin film; CZTS; secondary phases; solar cell; Engineering Science; Teknisk fysik;

    Abstract : Kesterite Cu2ZnSnS4 (CZTS) is interesting as a sustainable photovoltaic technology due to its earth-abundant elements and suitable semiconducting properties. To date, a record efficiency of 12.6% has been achieved but further improvements are required to reach high efficiency for industrial implementation. READ MORE

  4. 2. Annealing Based Optimization Methods for Signal Processing Applications

    Author : Per Persson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; annealing; digital filter design; adaptive filtering;

    Abstract : In this thesis, a class of combinatorial optimization methods rooted in statistical mechanics and their use in signal processing applications will be discussed. The thesis consists of two separate parts. READ MORE

  6. 4. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation

    Author : Verity Borthwick; Sandra Piazolo; Dorte Juul Jensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; halite; in-situ; X-ray diffraction; EBSD; annealing; substructure; modelling; Earth sciences; Geovetenskap; Geology; geologi;

    Abstract : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. READ MORE

  7. 5. Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction

    Author : Henrik Jönsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; 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.
