  2. 22. Modelling of Concrete Subjected to Cyclic Loading

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Rasmus Rempling; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyclic loading; plasticity; damage; concrete; energy dissipation;

    Sammanfattning : The infrastructure of today depends heavily on concrete structures. Most of these structuresare subjected to repeated loads, known as fatigue or cyclic loads: the loads weakenthe structure. As this phenomenon is of high cost to society, a deeper understanding ofthe deterioration process of cyclic loading would be beneficial. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modeling; Data Structures; Throughput; Concurrency; Energy Efficiency; Parallel Computing; Analysis; Performance; Lock-free;

    Sammanfattning : Concurrent data structures are key program components to harness the available parallelism in multi-core processors. Lock-free algorithmic implementations of concurrent data structures offer high scalability and possess desirable properties such as immunity to deadlocks, convoying and priority inversion. LÄS MER

  5. 25. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Detta är en avhandling från Food Engineering, Lund Univeristy

    Författare :Eva Ståhl Wernersson; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER
