  3. 2. Influence of running-in on gear efficiency

    Författare :Sören Sjöberg; Ulf Olofsson; Björklund Stefan; Lehtovaara Arto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; gear manufacturing; running-in; efficiency; friction; surface topography; Machine Design; Maskinkonstruktion;

    Sammanfattning : The general trend in gear industry is an increased focus on gear transmission efficiency. This thesis focuses on the understanding of how different gear manufacturing methods – particularly the contribution of the running-in process – affect the surface characteristics and friction response, with the purpose of increasing gearbox efficiency.

  4. 3. On the running-in of gears

    Författare :Sören Sjöberg; Ulf Olofsson; Anders Flodin; KTH; []
    Nyckelord :gears; gear manufacturing; running-in; surface topography; contact area ratio; manganese phosphate; Mechanical engineering; Maskinteknik;

    Sammanfattning : The general trend in gear industry, today, is an increased focus on gear transmission efficiency. Gear transmission efficiency losses arise from loaded and unloaded gear contacts, seals, lubricant and bearings. One way of minimising the losses is to lower the lubricant viscosity. This will reduce the speed dependent losses. LÄS MER

  5. 4. Between the Probe and the Pump : An experimental study on cardiac performance analysis based on Echocardiography, tissue and laser Doppler

    Författare :Laila Hübbert; Birgitta Janerot-Sjöberg; Ulf Dahlström; Sven-Erik Ricksten; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Echocardiography is an ultrasound-based bedside, non-invasive and easily available cardiac diagnostic technique visualising the heart’s morphology and function. Quantification of cardiac wall motion can be measured with the tissue Doppler Imaging (TDI) modality which provides in humans a high diagnostic capacity to differentiate healthy from diseased myocardium with reduced function.

  7. 5. "Emellan oss" : om de svenska uppsättningarna av Witold Gombrowicz Vigseln

    Författare :Janina Ludawska; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Gombrowicz; Witold; 1904-1969. Vigseln; Skådespelarkonst-- Sverige -- 1900-talet; Scenografi-- Sverige -- 1900-talet;

    Sammanfattning : The title ”Between Ourselves” alludes to one of the most important problems in Witold Gombrowicz's writings which finds full expression in his drama ”The Wedding” - that our thoughts and actions arise between us without our knowing where they will lead us. My study is concerned with productions of this drama in Sweden. LÄS MER
