  2. 21. Combinatorial Considerations on Two Models from Statistical Mechanics

    Author : Johan Thapper; Svante Linusson; Peter Jonsson; Jakob Jonsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fully packed loop model; rhombus tilings; hard particle model; independence complex; discrete morse theory; Discrete mathematics; Diskret matematik;

    Abstract : Interactions between combinatorics and statistical mechanics have provided many fruitful insights in both fields. A compelling example is Kuperberg’s solution to the alternating sign matrix conjecture, and its following generalisations. READ MORE

  4. 22. Topics in discrete random structures

    Author : Anders Martinsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; First--passage percolation; Cartesian power graph; third moment argument; jigsaw puzzle; shotgun assembly; monotone paths; non-Markovian coupling; high dimension; coupling inequality; monotone paths;

    Abstract : This thesis presents four papers on problems in discrete probability. A common theme of the articles is to take some class of discrete structures, impose some randomness, and then consider what happens asymptotically as the size of the structure tends to infinity. READ MORE

  6. 24. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

    Author : Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

    Abstract : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. READ MORE
