  1. 1. Boundary Value Problems for Nonlinear Elliptic Equations in Divergence Form

    Författare :Abubakar Mwasa; Jana Björn; Anders Björn; Tomas Sjödin; Sorina Barza; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The thesis consists of three papers focussing on the study of nonlinear elliptic partial differential equations in a nonempty open subset Ω of the n-dimensional Euclidean space Rn. We study the existence and uniqueness of the solutions, as well as their behaviour near the boundary of Ω. LÄS MER

  5. 4. Computational Free-Surface Flows Computational Techniques for Nonlinear Seepage Flow in Porous Media with Free and Moving Boundaries

    Författare :Nahidh Hamid Sharif; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear seepage flow; ICT; free boundary; LSM; CFD; two-fluid interfaces; FEM;

    Sammanfattning : Motion of a viscous fluid interface is encountered in many physical processes in engineering applications. The accurate representation and efficient numerical solution of the fluid interface are crucial problems in simulations of the physical processes in these applications. LÄS MER

  7. 5. Parabolic problems on noncylindrical domains : the method of Rothe

    Författare :Komil Kuliev; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This Licentiate Thesis deals with parabolic problems on non-cylindrical domains. The existence and uniqueness of the corresponding initial- boundary value problem is proved by the method of Rothe, which - for the case of non-cylindrical domains - has to be appropriately generalized and applied.
