  2. 16. Spark Assisted Compression Ignition, SACI

    Author : Håkan Persson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame propagation; PLIF; LDV; chemiluminescence imaging; residuals; negative valve overlap; low temperature combustion; SACI; spark assistance; HCCI; turbulence; charge stratification; cycle to cycle;

    Abstract : The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. READ MORE

  4. 17. Multiport Antenna Systems for Space-Time Wireless Communications

    Author : Nima Jamaly; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spatial Correlation; Multiport Matching Efficiency; Multiport Antennas; Uncorrelated Multipath.; Richness Threshold; Multiport Effective Length; Pattern Overlap Matrix; Multiport Effective Area; Non-rich Multipath; Covariance Matrix; Predictor Antenna System; Correlated Multipath;

    Abstract : Multiport antenna systems are indispensable part of modern wireless communication systems. Their crucial impact on the overall performance requires sufficient regard and dedication to a precise design and characterisation. This concern has been to a considerable extent addressed in the frame of the current thesis. READ MORE

  6. 19. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars

    Author : Ralejs Tepfers; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; splitting failures; confinement; deformed bars; tensile overlap splices; bond theory; fatigue; concrete cover splitting; reinforcement;

    Abstract : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. READ MORE
