  2. 1. Experimental Measurement of Lateral Force in a Submerged Single Heaving Buoy Wave Energy Converter

    Author : Andrej Savin; Mats Leijon; Magnus Karlberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; Tight mooring system; Offshore measurement; Strain gauge; Estimation of stress; Lateral force; Inclination angle; Snatch load; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The search for new solutions for the generation of energy is becoming more and more important for our future. Big arguments and disagreements on e.g. the questions of gas transport or the dependence on energy supplied by other countries raise demands on the development of new forms of alternative energy resources.

  4. 2. Investigation of Thermal Performance of Cylindrical Heatpipes Operated with Nanofluids

    Author : Morteza Ghanbarpourgeravi; Rahmatollah Khodabandeh; Björn Palm; Oronzio Manca; KTH; []
    Keywords : Nanofluid; heat pipe; thermal resistance; heat transfer coefficient; evaporator; condenser; wick; porous layer; heat flux; inclination angle; thermal conductivity; viscosity; Energiteknik; Energy Technology;

    Abstract : Nanofluids as an innovative class of heat transfer fluids created by dispersing nanometre-sizedmetallic or non-metallic particles in conventional heat transfer fluids displayed the potential toimprove the thermophysical properties of the heat transfer fluids. The main purpose of this study is toinvestigate the influence of the use of nanofluids on two-phase heat transfer, particularly on thethermal performance of the heat pipes. READ MORE

    Abstract : Today, the traditional insulator materials for high voltage powerlines, i.e. glass and porcelain, are gradually being replaced with new materials, most notably silicone rubber. READ MORE

  6. 4. Spiral Grain in Norway Spruce

    Author : Harald Säll; Thomas Thörnqvist; Rolf Birkeland; Växjö universitet; []
    Keywords : Spiral grain angle; drying deformation; warp; wood quality; Norway spruce; Picea abies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture. READ MORE

  7. 5. Prosthetic Foot Control for Ground Adaptation

    Author : Wolfgang Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomous systems; kinematical sensors; Foot prosthesis; embedded computing; sensor fusion;

    Abstract : Wearers of prosthetic feet find walking on inclined ground difficult or uncomfortable. A major reason for this is a limitation in ankle motion in existing prostheses. READ MORE
