  1. 1. Case studies in omniparametric simulation

    University dissertation from Göteborg : Göteborg University

    Author : Fredrik Lundin; Göteborgs universitet.; Gothenburg University.; [2006]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Long-Term Simulation of Coastal Evolution

    University dissertation from Water Resources Engineering, Lund University

    Author : Hoan Le Xuan; [2010]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Model Adaptivity in Elasticity

    University dissertation from Göteborg : Chalmers University of Technology

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

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : US AB

    Author : Jakob Erik Björnberg; KTH.; [2009]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Mathematical Learning Disability Cognitive Conditions, Development and Predictions

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Rickard Östergren; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical learning disability; dyscalculia; mathematical cognition; number sense; Matematiska inlärningssvårigheter; dyskalkyli; matematisk kognition; antalsuppfattning;

    Abstract : The purpose of the present thesis was to test and contrast hypotheses about the cognitive conditions that support the development of mathematical learning disability (MLD). Following hypotheses were tested in the thesis: a) domain general deficit, the deficit is primarily located in the domain general systems such as the working memory, b) number sense deficit, the deficit is located in the innate approximate number system (ANS), c) numerosity coding deficit, the deficit is located to a exact number representation system, d) access deficit, the deficit is in the mapping between symbols and the innate number representational system (e.
