  2. 1. 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

  4. 2. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

    Author : Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
    Keywords : Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

    Abstract : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. READ MORE

  5. 3. On Robotic Work-Space Sensing and Control

    Author : Magnus Linderoth; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

    Abstract : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. READ MORE

  6. 4. Non-covalent Modification of Graphene and MoS2 Synthesis and Characterization of Charged Molecules and Two-Dimensional Materials

    Author : Steffen Brülls; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sensors.; molybdenum disulfide; intermolecular interactions; charged π-conjugated systems; doping; non-covalent interactions; functionalization; cation; Graphene; anion;

    Abstract : Graphene is a material of superlatives. It has unique properties, which are explored in various areas of interdisciplinary research. Graphene can improve the properties of other materials or even give them new functions and is therefore a suitable candidate for different sensor applications. READ MORE

  7. 5. Wood and fibre mechanics related to the thermomechanical pulping process

    Author : Jan-Erik Berg; Per Engstrand; Per A. Gradin; Tomas Björkqvist; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic emission; Chips; Compression tests; Defibration; Disc refiners; Energy consumption; Fibre structure; Force sensors; Fracture; Impact strength; Mathematical analysis; Moisture content; Picea abies; Refining; Stiffness degradation; Strains; Temperature; Thermomechanical pulping; Velocity; Chemical engineering; Kemiteknik;

    Abstract : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. READ MORE
