  5. 9. 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

  7. 10. Modeling a carbon-nanotube-based nanoelectromechanical relay

    Författare :Magnus Jonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface forces; NEMS; carbon nanotubes; dissipation; nanorelay; mechanical resonances; stiction; high frequency applications; Nanoelectromechanical systems; field emission; tunable resonances;

    Sammanfattning : We have theoretically investigated the properties of a three-terminal carbon-nanotube-based nanoelectromechanical relay. The system operationis based on an coupling between electrical and mechanical degrees of freedom which is a typical characteristic of a NEMS device. LÄS MER
