    Sammanfattning : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. LÄS MER

  3. 2. Towards Natural Control of Artificial Limbs

    Författare :Max Jair Ortiz Catalan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epimysial electrodes; robotic prostheses; sensory feedback.; real-time and simultaneous prosthetic control; neurostimulation; pattern recognition; advanced prosthetic control; neural interfaces; artificial limbs; cuff electrodes; bone-anchored prostheses; osseointegration;

    Sammanfattning : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.

  4. 3. Removal of Micropollutants from Wastewater in Aerobic Granular Sludge and Activated Sludge Systems

    Författare :Cecilia Burzio; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Pharmaceuticals; Aerobic Granular Sludge; Microbial Community; Organic Micropollutants; Biofilm; Transformation; Sorption;

    Sammanfattning : The presence of organic substances in the aquatic environment, such as pharmaceutically active compounds, antibiotics, and personal care products, has become a worldwide issue of increasing environmental concern. As they are present at nano- to microgram per liter concentrations, they are defined as organic micropollutants (OMPs). LÄS MER

  5. 4. Novel catalysts development for NOx reduction from H2 combustion engines

    Författare :Jieling Shao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H2-SCR; SSZ-13 zeolite; in-situ DRIFTS; Iridium; Nitrogen selectivity; Platinum; reduction pretreatment; temperature intervals; BETA zeolite; Palladium;

    Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER

  7. 5. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures : In an Iron Ore Pelletizing Industry

    Författare :Erik A. A. Nilsson; Marta-Lena Antti; Ragnar Tegman; Jan-Erik Svensson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; Grate-Kiln; microstructure; corrosion; as-casted; thermal cycling; erosion; deposition; Engineering Materials; Materialteknik;

    Sammanfattning : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.
