  1. 11. Optimization of Point Absorber Wave Energy Parks

    Author : Marianna Giassi; Malin Göteman; Jens Peter Kofoed; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy arrays; genetic algorithm; optimization; WEC; hydrodynamic interaction; Engineering Science; Teknisk fysik;

    Abstract : Renewable energies are believed to play the key role in assuring a future of sustainable energy supply and low carbon emissions. Particularly, this thesis focus on wave energy, which is created by extracting the power stored in the waves of the oceans. READ MORE

  2. 12. Numerical and experimental modelling for wave energy arrays optimization

    Author : Marianna Giassi; Malin Göteman; Jan Isberg; Gregorio Iglesias; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy; Point absorber; Arrays; Parks; Farms; Optimization; Array layout; Genetic algorithm; Cost function; Wave tank experiment; Hydrodynamics; Economical model; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Many wave power conversion devices, especially point-absorbers, do not provide alone the necessary amount of converted electricity to be cost effective, instead they are designed to be deployed in arrays of many units. Such arrays, or parks, can satisfy a large-scale energy demand, reduce the costs of the produced electricity and improve the reliability of the system. READ MORE

  3. 13. Managing Geometrical Variation through Optimization and Visualization

    Author : Johan Lööf; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation simulation; tolerancing; Tolerance allocation; locating scheme optimization; geometry assurance; visualization of variation; tolerance analysis;

    Abstract : All manufacturing processes are afflicted by variation that causes deviations in critical dimensions in the final product. Geometrical variation results in form and size deviation in individual parts. Assembly variation comes from defects in assembly equipment, and influence how parts are mounted together. READ MORE

  4. 14. JOINING SEQUENCE ANALYSIS AND OPTIMIZATION FOR IMPROVED GEOMETRICAL QUALITY

    Author : Roham Sadeghi Tabar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency; Optimization; Sequencing; Geometrical Quality; Non-Rigid Variation Simulation; Joining;

    Abstract : Disturbances in the manufacturing and assembly processes cause geometrical variation from the ideal geometry. This variation eventually results in functional and aesthetic problems in the final product. Being able to control the disturbances is the desire of the manufacturing industry. READ MORE

  5. 15. MODELING AND OPTIMIZATION OF WASHING MACHINE VIBRATION DYNAMICS DURING SPINNING
