  1. 1. Case studies in omniparametric simulation

    Författare :Fredrik Lundin; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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; omnithermal simulation;

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

  2. 2. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

    Författare :Gisela Richardson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

    Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

  3. 3. Multiscale models and simulations for diffusion and interaction in heterogeneous domains

    Författare :Omar Malcolm Richardson; Adrian Muntean; Björn Engquist; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; multiscale modeling; finite element methods; interacting particle sytems; population dynamics; non-equilibrium dynamics; Matematik; Mathematics;

    Sammanfattning : We investigate multiscale and multiphysics models for evolution systems in heterogeneous domains, with a focus on multiscale diffusions. Although diffusion is often studied in terms of continuum observables, it is a consequence of the motion of individual particles. LÄS MER

  4. 4. Spatial distribution of snow in Antarctica and other glacier studies using ground-penetrating radar

    Författare :Cecilia Richardson-Näslund; Robert W. Jacobel; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; GPR; ground-penetrating radar; radar soundings; snow accumulation; accumulation rate; spatial variability; Antarctica; Dronning Maud Land; cold surface layer; thermal regime; glacial cirques; Sweden; Antarktis; Glaciärer; Ackumulering av snö; Geography; Physical Geography; geografi med naturgeografisk inriktning;

    Sammanfattning : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. LÄS MER
