  2. 1. Measurement, Modeling, and Characterization for Energy-Efficient Computing

    Author : Bhavishya Goel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; power-aware scheduling; power estimation; transactional memory; power measurement; power management; energy characterization;

    Abstract : The ever-increasing ecological footprint of Information Technology (IT) sector coupled with adverse effects of high power consumption on electronic circuits has increased the significance of energy-efficient computing in the last decade. Making energy-efficient computing a norm rather than an exception requires that system designers and programmers understand the energy implications of their design and implementation choices.

  4. 2. Wave Energy Converters : An experimental approach to onshore testing, deployments and offshore monitoring

    Author : Liselotte Ulvgård; Mats Leijon; Jonny Hylander; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; ocean energy; linear generator; measurements; sensors; point absorber; offshore; PTO; force; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The wave energy converter (WEC) concept developed at Uppsala University consists of a point absorbing buoy, directly connected to a permanent magnet linear generator. Since 2006, over a dozen full scale WECs have been deployed at the Lysekil Research Site, on the west coast of Sweden. READ MORE

  5. 3. Energy-Efficient Data Converters for Low-Power Sensors
