    Detta är en avhandling från Sölvegatan 14 A, 223 62 Lund , Sweden

    Författare :Martin Lagerholm; Lund University.; Lunds universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Potts; combinatorial optimization; ANN; mean field; approximation; routing; unicast; multicast; airline crew; scheduling; ECG; NP-complete.; Matematik; Mathematics; algorithm; Systems engineering; computer technology; Data- och systemvetenskap; Fysicumarkivet A:1998:Lagerholm;

    Sammanfattning : Potts mean field artificial neural network techniques are developed and applied to airline crew scheduling problems and routing problems. A propagator formalism in terms of Potts neurons is developed to handle global topological issues. An integrated method for identifying and classifying ECG complexes is presented. LÄS MER

  2. 2. Mean Field Games for Jump Non-Linear Markov Process

  4. 4. Polyelectrolyte - Surfactant Interactions in Dilute Suspensions. A Study Based on Monte Carlo simulations and Mean-Field Calcultations

    Detta är en avhandling från Department of Physical Chemistry, Lund University

    Författare :Torsten Wallin; Lund University.; Lunds universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aggregation number; linear charge density; chain flexibility; mean-field; calculation; simulation; Monte Carlo; cmc; cac; interaction; electrostatic; charged; micelle; polyelectrolyte; surfactant; hydrophilic; hydrophobic; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The complexation of macroions or charged micelles and oppositely charged polyelectrolytes was studied by the use of Monte-Carlo simulations and mean field calculations. The Monte-Carlo simulations were performed on a simple model system with the emphasis on the electrostatic interaction, (i) polyelectrolyte rigidity, (ii) polyelectrolyte linear charge density, (iii) surfactant tail length, and (iv) the polyelectrolyte concentration.

  5. 5. Correlated Electronic Structure of Materials Development and Application of Dynamical Mean Field Theory

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Patrik Thunström; Uppsala universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; DMFT; correlation; entanglement; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : This thesis is dedicated to the development, implementation and application of a combination of Density Functional Theory and Dynamical Mean Field Theory. The resulting program is shown through several examples to be a powerful and flexible tool for calculating the electronic structure of strongly correlated materials. LÄS MER
