  1. 1. Case studies in omniparametric simulation

    Detta är en avhandling från Göteborg : Göteborg University

    Författare :Fredrik Lundin; Göteborgs universitet.; Gothenburg University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; growth model; Ising model; Markov chain; omnithermal simulation; omniparametric simulationpercolatiion; Potts model; parameter estimation; partial observations; random cluster model; Richardson model; simulation driven parameter estimation; two-type Richardson model;

    Sammanfattning : In the eld of particle systems and growths models simulation is an importanttool. When explicit calculations are too complex or impossibleto perform we may use simulations instead. We adapt a new techniquehere denoted omniparametric simulation, to the two-type Richardson,Ising and Potts models. LÄS MER

  2. 2. Long-Term Simulation of Coastal Evolution

    Detta är en avhandling från Water Resources Engineering, Lund University

    Författare :Hoan Le Xuan; Lunds universitet.; Lund University.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Sammanfattning : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. LÄS MER

  3. 3. Model Adaptivity in Elasticity

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :David Heintz; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; dimension reduction; a posteriori error; model error; model adaptivity;

    Sammanfattning : We consider model adaptivity in elasticity for dimensionally reduced forms, and shall treat different conceptual approaches. The basic idea, however, is to adaptively refine, not only the computational mesh, but also the underlying mathematical formulation. LÄS MER

  4. 4. Graphical representations of Ising and Potts models Stochastic geometry of the quantum Ising model and the space-time Potts model

    Detta är en avhandling från Stockholm : US AB

    Författare :Jakob Erik Björnberg; KTH.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; MATHEMATICS Algebra; geometry and mathematical analysis Discrete mathematics; MATEMATIK Algebra; geometri och analys Diskret matematik;

    Sammanfattning : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Rotational bands; Shell model; Cranked Nilsson-Strutinsky; Pairing interaction; Backbending; Band termination; Proton-neutron pairing; Quadrupole electromagnetic moments and transition strengths; N=Z nuclei; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; Fysicumarkivet A:2000:Juodagalvis; termodynamik; statistisk fysik; kvantmekanik; relativitet;

    Sammanfattning : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. LÄS MER
