  1. 1. Hydrokinetic Resource Assessment : Measurements and Models

    Författare :Emilia Lalander; Mats Leijon; Mitsuhiro Kawase; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The conversion of kinetic energy in water currents into electricity has gained great attention the past years. The conversion systems are stand-alone units that typically consist of a turbine, driven by the water stream, with a generator connected to it. LÄS MER

  3. 2. Hydro-Kinetic Energy Conversion : Resource and Technology

    Författare :Mårten Grabbe; Mats Leijon; Cameron Johnstone; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tidal energy; renewable energy; vertical axis turbine; permanent magnet generator; resource assessment; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The kinetic energy present in tidal currents and other water courses has long been appreciated as a vast resource of renewable energy. The work presented in this doctoral thesis is devoted to both the characteristics of the hydro-kinetic resource and the technology for energy conversion. LÄS MER

  4. 3. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products

    Författare :Hampus André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; scarce metals; life cycle assessment; resource-efficiency; electronic products; resource depletion; circular economy; metal resource use;

    Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER

  5. 4. Marine Current Resource Assessment : Measurements and Characterization

    Författare :Nicole Carpman; Karin Thomas; Mats Leijon; Sandra Eriksson; Mairead Atcheson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADCP; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. LÄS MER

  7. 5. From resource efficiency to resource conservation : Studies, developments and recommendations for industrial implementation of circular manufacturing systems

    Författare :Michael Lieder; Amir Rashid; Tomohiko Sakao; KTH; []
    Nyckelord :Circular economy; Circular manufacturing systems; Resource conservative manufacturing; ResCoM; Agent-based modelling; Multi-method modelling; Production Engineering; Industriell produktion;

    Sammanfattning : Manufacturing industry is under permanent pressure to maintain its economic growth and profitability as strong societal backbone. At the same time pressures of waste generation and resource consumption are increasing as result of manufacturing operations. LÄS MER
