  1. 1. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Detta är en avhandling från Kemiska institutionen, Lunds universitet

    Författare :Jasper Immink; [2019-03]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

    Sammanfattning : Severe accidents in a Light Water Reactor (LWR) have been a subject of intense research for the last three decades. The research in this area aims to reach understanding of the inherent physical phenomena and reduce the uncertainties in their quantification, with the ultimate goal of developing models that can be applied to safety analysis of nuclear reactors, and to evaluation of the proposed accident management schemes for mitigating the consequences of severe accidents.

  3. 3. Modelling of Granular Materials

    Detta är en avhandling från KTH : KTH

    Författare :Aylin Ahadi; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; materialteknik; Materiallära; Material technology; binary mixture model; simulations; material modelling; finite element; granular materials; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3.

  4. 4. Statistical Segmentation and Registration of Medical Ultrasound Data

    Detta är en avhandling från KTH : KTH

    Författare :Mattias Hansson; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

    Sammanfattning : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. LÄS MER

  5. 5. Interfacial behaviour of surfactants and enzymes: studies at model surfaces

    Detta är en avhandling från Britt Nyström, YKI Ytkemiska Institutet AB, Box 5607, SE-114 86 Stockholm, Sweden, [email protected]
