  2. 11. Computational studies of passive vortex generators for flow control

    Author : Florian von Stillfried; Arne Johansson; Stefan Wallin; Sinisa Krajnovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passive flow control; vortex generator; statistical modelling; turbulence; separation prevention; flat plate; diffuser; high-lift design; airfoil; Fluid mechanics; Strömningsmekanik;

    Abstract : Many flow cases in fluid dynamics face undesirable flow separation due torising static pressure on wall boundaries. This occurs e.g. due to geometry as ina highly curved turbine inlet duct or e. READ MORE

  4. 12. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization

    Author : Fritiof Wallentin; Andrei Khrennikov; Kisil Vladimir; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; contextuality; probabilistic interpretation; Born’s rule; frequentist interpretation; unitary representations; classical statistical mechanics; Koopman-von Neumann formulation; hidden-variable model; quantization.; Matematik; Mathematics;

    Abstract : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

  5. 13. Thermodynamics of Protein Folding and Design

    Author : Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

    Abstract : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. READ MORE

  6. 14. 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.

  7. 15. Hydrophobicity Patterns in Protein Folding

    Author : Frank Potthast; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global optimization; multisequence; Fourier analysis; hydrophobicity; protein folding; simulated tempering; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; gravitation; relativitet; termodynamik; statistisk fysik; alpha-helix; protein design.; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; relativity; Fysicumarkivet A:1998:Potthast;

    Abstract : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. READ MORE
