    Sammanfattning : Numerical simulation methods have become an important tool in the study of chemical reaction networks in living cells. Many systems can, with high accuracy, be modeled by deterministic ordinary differential equations, but other systems require a more detailed level of modeling. LÄS MER

  4. 4. Adaptivity for Stochastic and Partial Differential Equations with Applications to Phase Transformations

    Detta är en avhandling från Stockholm : KTH

    Författare :Erik von Schwerin; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Sammanfattning : his work is concentrated on efforts to efficiently compute properties of systems, modelled by differential equations, involving multiple scales. Goal oriented adaptivity is the common approach to all the treated problems. LÄS MER
