    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

    Sammanfattning : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. LÄS MER

  4. 8. Active cellular forces in variable mechanical microenvironments

    Författare :Adele Khavari; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traction force; Gradient substrate; Alginate 3D culture; Durotaxis; mechanics;

    Sammanfattning : Our bodies are immensely complex structures, with various systems, organs, and processes that are not only biochemically driven, but strongly dependent on physical mechanics.  At the heart of all these processes are cells, which must generate forces to adhere, spread, differentiate, grow, and move.

  5. 9. Reduction of Audible Noise of a Traction Motor at PWM Operation

    Författare :Hanna Amlinger; Ines Lopez Arteaga; Siv Leth; Wolfgang Kropp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic noise; pulse width modulation PWM ; switching frequency; traction motor; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : A dominating source for the radiated acoustic noise from a train at low speeds is the traction motor. This noise originates from electromagnetic forces acting on the structure resulting in vibrations on the surface and thus radiated noise. It is often perceived as annoying due to its tonal nature.

  7. 10. Traction force and long-term outcome in children born after vacuum-assisted delivery

    Författare :Stefhanie Romero; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Vacuum-assisted delivery (VAD) is used in cases of dystocia or foetal distress in the second stage of labour. The frequency of VADs differs around the world, and in Sweden they account for six to nine percent of all deliveries. LÄS MER
