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

    Author : Jan Frykestig; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advancing front method; mesh size distribution; automatic mesh generation; finite element method; surface mesh generation; spatial data structures;

    Abstract : 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. 2. Towards adaptive mesh refinement in Nek5000

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

    Abstract : 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. READ MORE

  5. 3. 5G Backhauling with Software-defined Wireless Mesh Networks

    Author : Ricardo Santos; Andreas Kassler; Rui L. Agar; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SDN; wireless backhaul; heterogeneous networks; mmWave; 5G; resiliency; Computer Science; Datavetenskap;

    Abstract : Current technological advances have caused an exponential growth of the number of mobile Internet-connected devices, along with their respective traffic demands. To cope with this increase of traffic demands, fifth generation (5G) network architectures will need to provide multi-gigabit capacity at the access base stations (BSs), through the deployment of ultra-dense small cells (SCs) operating with millimeter-wave (mmWave) frequencies, e.

  6. 4. Generation of Patient Specific Finite Element Head Models

    Author : Johnson Ho; Svein Kleiven; Michael Gilchrist; KTH; []
    Keywords : Injury Prevention; Patient Specific; Finite Element Head Model; Anatomical Structures; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Traumatic brain injury (TBI) is a great burden for the society worldwide and the statisticsindicates a relative constant total annual rate of TBI. It seems that the present preventativestrategies are not sufficient. To be able to develop head safety measures against accidents ine.g. READ MORE

  7. 5. On Noise Generation and Dynamic Transmission Error of Gears

    Author : Mats Henriksson; Leping Feng; Reader Andy Moorhouse; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Abstract : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.
