  1. 1. Pulsed Electric Field Treatment of Plant Tissue

    Författare :Mustafa Fincan; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bimodal Fickian diffusion model; Food and drink technology; Livsmedelsteknik; generalized Maxwell model; onion Neutral Red; visualization; red beetroot; potato; epidermis; plant tissue; electroporation; Cell permeabilization; Pulsed electric field; PEF;

    Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER

  3. 2. Finite volume solvers for the Maxwell equations in time domain

    Författare :Fredrik Edelvik; Per Lötstedt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : Two unstructured finite volume solvers for the Maxwell equations in 2D and 3D are introduced. The solvers are a generalization of FD–TD to unstructured grids and they use a third-order staggered Adams–Bashforth scheme for time discretization. LÄS MER

  4. 3. Future stability of the Einstein-Maxwell-Scalar field system and non-linear wave equations coupled to generalized massive-massless Vlasov equations

    Författare :Christopher Svedberg; Hans Ringström; Alan Rendall; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two articles related to mathematical relativity theory. In the first article we prove future stability of certain spatially homogeneous solutionsto Einstein’s field equations. The matter model is assumed to consist of an electromagnetic field and a scalar field with a potential creating an accelerated expansion. LÄS MER

  5. 4. Some Problems in Kinetic Theory and Applications

    Författare :Åsa Windfäll; Alexander Bobylev; Giampiero Spiga; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This thesis consists of four papers. the first is devoted to discrete velocity models, the second to hydrodynamic equation beyond Navier-Stokes level, the third to a multi-linear Maxwell model for economic or social dynamics and the fourth is devoted to a function related to the Riemann zeta-function.
