  2. 1. Axon Guidance and Morphogenesis of the C. elegans Pharynx

    Author : Manish Rauthan; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharynx; M2; C. elegans; extra-cellular matrix ECM ; hex; Krüppel; pha-2; isthmus; NSM; pharyngeal neurons.; cytoskeleton; mnm-2;

    Abstract : The C. elegans pharynx is a single cell thick muscular tube that undergoes morphogenesis to attain it mature structure from a ball of 80 undifferentiated cells. This thesis is about understanding the mechanisms and the genetic pathways underlying the process of pharyngeogenesis. READ MORE

  4. 2. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Author : Frida Svelander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Abstract : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. READ MORE

  5. 3. Modeling and Performance Analysis of Alternative Heat Exchangers for Heavy Vehicles

    Author : Wamei Lin; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Countercurrent flow; Graphite foam; Heat exchanger; Thermal performance; Computational fluid dynamics;

    Abstract : Cross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles.

  6. 4. Energy Relevant Materials: Investigations Based on First Principles

    Author : Erna-Krisztina Delczeg-Czirjak; Levente Vitos; Manuel Richter; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magneto-caloric; DFT; elastic constants; Materials science; Teknisk materialvetenskap;

    Abstract : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. READ MORE

  7. 5. Accuracy of virtually planned and CAD/CAM-guided dental implant surgery

    Author : Andreas Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : dental implant;

    Abstract : The treatment with dental implants was introduced in the 1960s as an aid for patients who were missing teeth. Recently CAD/CAM guided surgical concepts have been launched on the market as a solution for treating single, partial or completely edentulous patients with dental implants. READ MORE
