  2. 1. Particle Characterization in the Exhaust Devices of Direct Injection Engines

    Author : Arun Prasath Karuppasamy; Anders Christiansen Erlandsson; Hanna Bernemyr; Alexander Bergmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle number; Particle size distribution; turbocharger; SCR; Exhaust after-treatment system; Particle dilution and conditioning; Partikelantal; storleksfördelning av partiklar; turboladdare; SCR; efterbehandlingssystem; avgasbehandlingssystem; partikelspädning och partikelanpassad mätmetod; Machine Design; Maskinkonstruktion;

    Abstract : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. READ MORE

  4. 2. Importance of the particle shape on mechanical properties of soil materials

    Author : Juan Rodriguez; Sven Wallman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Particle shape of soil aggregates is known to influence several engineering properties; such as the internal friction angle, the permeability, etc. Even if this is known, there has been only minor progress in explaining the processes behind its performance and has only partly implemented in practical geotechnical analysis.

  5. 3. Healthcare interventions in children with congenital limb reduction deficiency : long term outcomes and experiences of decisions made during childhood

    Author : Lis Sjöberg; Liselotte Hermansson; Carin Fredriksson; Helen Lindner; Mats Granlund; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood; daily occupation; decision-making; family-centered service; life situation; limb deficiency; myoelectric prosthesis; parental role; rehabilitation; surgery;

    Abstract : The overall aim of this thesis was to describe experiences and long-term outcomes of healthcare interventions for children with congenital limb reduction deficiency (CLRD). The four studies included were conducted with descriptive designs. READ MORE

  6. 4. Experimental test setups and simulations in skiing mechanics

    Author : Mikael Swarén; Anders Eriksson; Thomas Stöggl; KTH; []
    Keywords : sports equipment; test methods; sports mechanics; alpine skiing; cross-country skiing; poles; helmets; glide; performance;

    Abstract : Product testing and development are essential parts in sports and for the athletes in their quest to reach the podium. Manufacturers of sports equipment often use basic test methods which do not test the equipment in a sports specific way. READ MORE

  7. 5. Electron Transport in Low Dimensional Systems

    Author : Peter Ramvall; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high mobility; low-dimensional structures; III-V semiconductors; quantum wells; heterojunctions; quantum Hall effect; edge channels; Shubnikov-de Haas effect; alloy-disorder scattering; Y-branch switch; two dimensional electron gas; Fysik; Fysicumarkivet A:1996:Ramvall; Physics; spin splitting; mag;

    Abstract : This thesis consists of experimental studies of transport properties in high mobility two dimensional electron gases (2DEGs). Two material systems are used, an AlGaAs/GaAs heterojunction and a GaInAs/InP quantum well. READ MORE
