  2. 16. Durability evaluation of PEM fuel cell components

    Author : Live Mølmen; Peter Leisner; Lars Fast; Frode Seland; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Proton exchange membrane fuel cell; bipolar plate; corrosion; interfacial contact resistance; electrocatalysis; Polymermembranbränsleceller; bipolära plattor; korrosion; kontaktresistans; katalys;

    Abstract : Proton exchange membrane fuel cells (PEMFCs) are used to convert hydrogen and oxygen to electricity, heat, and water. There are no greenhouse gas emissions, given that the hydrogen is produced from renewable sources, such as water electrolysis from wind, hydro or solar energy. READ MORE

  4. 17. Experiments on sheet metal shearing

    Author : Emil Gustafsson; Magnus Eriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Simulering av klippning i höghållfast stål;

    Abstract : Within the sheet metal industry, different shear cutting technologies are commonly used in several processing steps, e.g. in cut to length lines, slitting lines, end cropping etc. READ MORE

  5. 18. On Zero-dimensional Modelling of Combustion and NOx Formation in Diesel Engines

    Author : Rolf Egnell; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; Motors and propulsion systems; NOx Formation; Zero-Dimensional; Modelling; Diesel Engines; Termisk teknik; Thermal engineering; applied thermodynamics; termodynamik;

    Abstract : Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. READ MORE

  6. 19. On Kinematic Modelling and Iterative Learning Control of Industrial Robots

    Author : Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Geir Hovland; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; kinematics; Maple; modelling; iterative learning control; experiments; Automatic control; Reglerteknik;

    Abstract : Good models of industrial robots are necessary in a variety of applications, such as mechanical design, performance simulation, control, diagnosis, supervision and offline programming. This motivates the need for good modelling tools. In the first part of this thesis the forward kinematic modelling of serial industrial robots is studied. READ MORE

  7. 20. Design and application of experimental methods for steel sheet shearing

    Author : Emil Gustafsson; Mats Oldenburg; Per Gradin; Lars Karlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Simulering av klippning i höghållfast stål;

    Abstract : Shearing is the process where sheet metal is mechanically cut between two tools. Various shearing technologies are commonly used in the sheet metal industry, for example, in cut to length lines, slitting lines, end cropping etc. READ MORE
