    Sammanfattning : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. LÄS MER

  3. 22. Power dissipation in car tyres

    Författare :Martin Fraggstedt; Svante Finnveden; Michael Brennan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. LÄS MER

  5. 24. Modelling of Concrete Subjected to Cyclic Loading

    Författare :Rasmus Rempling; Chalmers tekniska högskola; []
    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

  7. 25. Data Access Techniques for Enhanced Energy Efficiency and Performance in In-order Pipelines

    Författare :Alen Bardizbanyan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Cache; Pipeline; Energy Efficiency; Data Access; Performance;

    Sammanfattning : Energy efficiency is one of the key metrics in the design of a widerange of processor types. For example, battery powered devices, whichare growing in numbers every day, require energy efficient processorsto be able to operate for a useful period of time. LÄS MER
