  1. 1. Mesh-Based Immediate Breast Reconstruction. Complicantions and long-term results

    Författare :Håkan Hallberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immediate breast reconstruction; acellular dermal matrix; mesh; plastic surgery; quality of life;

    Sammanfattning : There are few high-quality studies evaluating use of meshes in implant-based immediate breast reconstruction (IBR). This thesis analyzed current evidence of matrices and compared outcomes from the use of biological or synthetic meshes and traditional muscle-covered implants. LÄS MER

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

    Författare :Jan Frykestig; Chalmers University of Technology; []
    Nyckelord :advancing front method; mesh size distribution; automatic mesh generation; finite element method; 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.

  4. 3. Towards adaptive mesh refinement in Nek5000

    Författare :Nicolas Offermans; Philipp Schlatter; Adam Peplinski; Paul Fischer; Chris Cantwell; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; Engineering Mechanics; Teknisk mekanik;

    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

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

    Författare :Magnus Hallén; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hernia repair; groin hernia; inguinal hernia; Lichtenstein; TEP; mesh; male infertility;

    Sammanfattning : Background: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery.

  7. 5. Computational modelling of machining - Mesh objective ductile damage modelling

    Författare :SENAD RAZANICA; Chalmers University of Technology; []
    Nyckelord :ductile damage; fracture modeling; Mesh dependence; machining process; visco-plastic Johnson- Cook; simulation tool; FEM;

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