  1. 16. Regulation of Microvascular Blood Flow : a clinical and experimental study based on laser Doppler perfusion imaging

    Författare :Helena Golster; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Local blood flow reflexes in the foot skin of healthy controls and in young diabetic patients with or without nerve dysfunction have been studied using laser Doppler perfusion imaging (LDPI). A neurophysiological follow-up study on nerve dysfunction is presented as a complerhent to the work on blood flow regulation in the young diabetics. LÄS MER

  3. 17. Architecture and Applications of a Geovisual Analytics Framework

    Författare :Quan Ho; Mikael Jern; Gennady Andrienko; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GeoVisual Analytics; toolkits; frameworks; web-enabled; visualization; interactive visualizations; interaction; interaction techniques; visual data analysis; component architecture; storytelling;

    Sammanfattning : The large and ever-increasing amounts of multi-dimensional, multivariate, multi-source, spatio-temporal data represent a major challenge for the future. The need to analyse and make decisions based on these data streams, often in time-critical situations, demands integrated, automatic and sophisticated interactive tools that aid the user to manage, process, visualize and interact with large data spaces.

  4. 18. Entrained flow gasification of biomass : On atomisation, transport processes and gasification reactions

    Författare :Mikael Risberg; Kevin Whitty; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Since the energy consumption in the world is increasing together with an increase of greenhouse gas emission it is of importance to find alternatives to fossil fuels. Biomass is one of the alternative energy sources which is both renewable and CO2 neutral. LÄS MER

  5. 19. Experimental Studies of Effusion Cooling

    Författare :Bernhard Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; laser-Doppler anemometry; infrared thermography; film cooling; flow visualization; full coverage film cooling; jet in crossflow; effusion cooling;

    Sammanfattning : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. LÄS MER

  7. 20. Analysis of Turbulent Flows-From Chaos to Structure

    Författare :Farideh Ghasempour; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; Vortex dynamics; Turbulence; Flow visualization; Vortex statistics; Coherent structure;

    Sammanfattning : The development of models for several phenomena occurring in turbulent single and multi-phase flows requires improved description and quantification of turbulent structures. Phenomena such as, for example, mixing, coalescence and break-up, are often fast and nonlinear. LÄS MER
