  2. 1. Surface Integrity Characterization of Gears with respect to Running-in

    Author : Dinesh Mallipeddi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micropitting; surface asperities; running-in; surface roughness; residual stresses; Gears; surface chemistry;

    Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. READ MORE

  5. 3. Material characterization for magnetically confined fusion : Surface analysis and method development

    Author : Petter Ström; Marek Rubel; Per Petersson; Thierry Loarer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid-twentieth century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

  7. 5. Enabling Surface Cleaning Robot for Large Food Silo

    Author : Kinan Dandan; Amy Loutfi; Lars Karlsson; Mikael Ekström; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Confined space; surface cleaning robot; motion control; static and dynamic analysis;

    Abstract : Working conditions in the dry cleaning and sanitation of confined interior spaces are often extreme, and workers need overall protection with tight clothing, helmets, face mask, earmuffs, and respirators. The environment is dirty, noisy with bad visibility and heavy with a high static work load. READ MORE
