1. 1. Interacting particle systems for opinion dynamics: the Deffuant model and some generalizations

   Författare :Timo Hirscher; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deffuant model; bounded confidence; opinion dynamics; sociophysics; consensus formation; general opinion space; percolation; pumpless water transport.; opinion dynamics;

   Sammanfattning : In the field of sociophysics, concepts and techniques taken from statistical physics are used to model and investigate some social and political behavior of a large group of humans: their social network is given by a simple graph and neighboring individuals meet and interact in pairs or small groups. Although most of the established models feature rather simple microscopic interaction rules, the macroscopic long-time behavior of the collective often eludes an analytical treatment due to the complexity, which stems from the interaction of the large system as a whole.

3. 2. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

   Författare :Ola Karlsson; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

   Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER

4. 3. Combinatorial Considerations on Two Models from Statistical Mechanics

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

   Sammanfattning : 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. LÄS MER

   Sammanfattning : Filtration as a means of separating solids from liquids is an important unit operation employedin a range of different industrial sectors, e.g. forest products, mineral, chemical process andpharmaceutical industries to name but a few. LÄS MER

7. 5. Soft resummation and hard evolution : Renormalization group methods in effective theories and multi scalar models

   Författare :Joel Oredsson; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higgs; Particle physics; two-Higgs-doublet model; Soft-Collinear-Effective Theory; Renormalization;

   Sammanfattning : This thesis is composed out of five papers that deal with various problems intheoretical particle physics. While paper I is a precision calculation in aneffective theory of the Standard Model, paper II to V all deal with beyond theStandard Model physics. Paper IV is a manual for the tools developed during ourwork on paper II to V.Paper I. LÄS MER
