  1. 1. Advancing Front Mesh Generation Techniques with Application to the Finite Element Method

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jan Frykestig; Chalmers tekniska högskola.; Chalmers University of Technology.; [1994]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture; Teknisk mekanik; Engineering mechanics; finite element method; automatic mesh generation; advancing front method; mesh size distribution; surface mesh generation; spatial data structures;

    Sammanfattning : The present study deals with automatic mesh generation with application to finite element methods. We focus our interest on unstructured mesh generation, and in particular on advancing front methods for which algorithms for meshing of two and three dimensional domains as well as of free-form surfaces are devised.

  2. 2. Towards adaptive mesh refinement in Nek5000

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Nicolas Offermans; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The development of adaptive mesh refinement capabilities in the field of computational fluid dynamics is an essential tool for enabling the simulation of larger and more complex physical problems. While such techniques have been known for a long time, most simulations do not make use of them because of the lack of a robust implementation. LÄS MER

  3. 3. Male inguinal hernia repair with mesh. Short- and long-term results and the question of infertility

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Sammanfattning : Abstract To strengthen the competitiveness the manufacturing industry strives for a continuous development of cost efficient manufacturing processes and improved product quality. These research and development issues are addressed by increasing the implementation of simulation tools based on finite element method (FEM). LÄS MER

  5. 5. Enhancing P2P Systems over Wireless Mesh Networks

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Marcel Cavalcanti de Castro; Karlstads universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer overlay; wireless mesh networks; peer selection; channel assignment; routing; optimization; adjacent channel interference; channel bandwidth adaptation; Datavetenskap; Computer Science;

    Sammanfattning : Due to its ability to deliver scalable and fault-tolerant solutions, applications based on the peer-to-peer (P2P) paradigm are used by millions of users on the internet. Recently, wireless mesh networks (WMNs) have attracted a lot of interest from both academia and industry, because of their potential to provide flexible and alternative broadband wireless internet connectivity.
