  3. 2. Compressor Modeling for Control of Automotive Two Stage Turbochargers

    Författare :Oskar Leufvén; Lars Eriksson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : There is a demand for increasing efficiency of automotive engines, and one way to achieve this is through downsizing and turbocharging. In the design compromises are made, for example the maximum power of the engine determines the size of the compressor, but since the compressor mass flow range is limited, this affects the torque for low engine speeds.

  4. 3. Anaerobic Treatment of Agricultural Residues and Wastewater - Application of High-Rate Reactors

    Författare :Wilson Parawira; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; opaque beer brewery wastewater; UASB; two-stage; co-digestion; sugar beet leaves; solid potato waste; methane yield; biogas; Anaerobic digestion; agricultural residues;

    Sammanfattning : The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. LÄS MER

  5. 4. A Two-stage Numerical Procedure for an Inverse Scattering Problem

    Författare :John Bondestam Malmberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coefficient inverse problem; inverse scattering; backscattering data; approximate global convergence; finite element method; adaptivity; a posteriori error analysis; a posteriori error analysis;

    Sammanfattning : In this thesis we study a numerical procedure for the solution of the inverse problem of reconstructing location, shape and material properties (in particular refractive indices) of scatterers located in a known background medium. The data consist of time-resolved backscattered radar signals from a single source position. LÄS MER

  7. 5. Autogenous free tooth transplantation with a two-stage operation technique

    Författare :Gunnar Nethander; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : If tooth transplantation is to succeed, it is crucial to preserve the vitality of the cells on the root surface of the tooth transplant. Insufficient nutrition, postoperatively, to the cells on the root surface of the tooth transplant was thought to contribute to devitalisation of these cells. LÄS MER
