  1. 1. Homogenization of pseudoparabolic reaction-diffusion-mechanics systems : Multiscale modeling, well-posedness and convergence rates

    Författare :Arthur J. Vromans; Adrian Muntean; Claudia Timofte; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reaction-diffusion-mechanics system; parameter delimitation; parabolic-pseudoparabolic equations; weak solvability; Rothe method; periodic homogenization; corrector estimates; vanishing thin domains; Matematik; Mathematics;

    Sammanfattning : In this dissertation, parabolic-pseudoparabolic equations are proposed to couple chemical reactions, diffusion, flow and mechanics in heterogeneous materials using the framework of mixture theory. The weak solvability is obtained in a one dimensional setting for the full system posed in a homogeneous domain - a formulation which we have obtained using the classical mixture theory. LÄS MER

  5. 4. Organic Synthesis in Nonionic Microemulsions

    Författare :Maria Häger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic reaction; phase behaviour; microemulsion; reaction kinetics;

    Sammanfattning : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. LÄS MER

  7. 5. Improving network layer reaction times

    Författare :Pierre Fransson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This thesis presents two proposals for improving network layer reaction times and an investigation into the consequences of using IPv4 options. The first proposal, the Selective TRuncating Internetworking Protocol (STRIP), is an augmentation of the IP networking layer. LÄS MER
