  2. 1. Developing Computational Methods for Moored Floating Wave Energy Devices

    Author : Johannes Palm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave Power; RANS simulations; Discontinuous Galerkin; Mooring Dynamics;

    Abstract : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. READ MORE

  4. 2. Mixing of Large Solids in Fluidized Beds

    Author : Anna Köhler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluidized beds; magnetic particle tracking; drag; semiempirical modelling; fluid-dynamic downscaling;

    Abstract : Fluidization is a technology that is widely used in systems in which particulate solids are to be transported, mixed, and/or reacted with gases. In fluidized bed applications, the lateral mixing rate of the solids and the heat and mass transfer with their surroundings play important roles in process performance. READ MORE

  5. 3. Performance and Flotation-REST in Tests of Marksmanship, Problem-solving and Perceived Exertion

    Author : Henrik Bergman; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Flotation-REST; archery; performance; primary- and secondary process; creativity; originality; EMG;

    Abstract : This present thesis examines whether or not relaxation as floating may be exploited to reinforce primary process (inner-directed) orientation, and thereby enhance performance, creative problem-solving ability and originality. Two Articles are presented both using randomized factorial design. Article I include two subexperiments. READ MORE

  6. 4. Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation

    Author : Konstantinos Chandolias; Hariklia N. Gavala; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; syngas fermentation; CH4; H2; cell washout; inhibitors; mass transfer; Resource Recovery; Resursåtervinning;

    Abstract : of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. READ MORE

  7. 5. Modelling and Advanced Control of Fully Coupled Wave Energy Converters Subject to Constraints: the Wave-to-wire Approach

    Author : Liguo Wang; Jan Isberg; Jørgen Hals Todalshaug; Uppsala universitet; []
    Keywords : Ocean wave energy; marine energy converter; wave energy converter; wave energy farm; potential flow theory; linear permanent magnet generator; control strategy; wave-to-wire approach; physical constraints; power generation control.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Ocean wave energy is a promising renewable source to contribute to supplying the world’s energy demand. The Division of Electricity at Uppsala University is developing a technology to capture energy from ocean waves with a wave energy converter (WEC) consisting of a linear permanent magnet generator and a point absorber.
