  2. 6. Ocean Wave Energy : Underwater Substation System for Wave Energy Converters

    Author : Magnus Rahm; Mats Leijon; Ted Brekken; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy; wave power; wave energy converter; direct-drive; permanent magnet linear generator; point absorber; array; farm; park; offshore; marine; substation; electrical transmission system; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : This thesis deals with a system for operation of directly driven offshore wave energy converters. The work that has been carried out includes laboratory testing of a permanent magnet linear generator, wave energy converter mechanical design and offshore testing, and finally design, implementation, and offshore testing of an underwater collector substation.

  4. 7. District heating comes to town : The social shaping of an energy system

    Author : Jane Summerton; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; district heating; municipal technology; energy system; pipeline; large t<:chnical system; actor network; multiorganization; grid; grid-based energy system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This thesis deals with the introduction of district heating in an "ordinary" Swedish town: Mjölby. The process was initiated in 1974 and the decision to build was taken in 1979. In the following years pipelines were laid down and the system was gradually built. In 1987, a permanent heat plant was ready to assume operation. READ MORE

  5. 8. Homotopy Theory and TDA with a View Towards Category Theory

    Author : Sebastian Öberg; Wojciech Chachólski; David Blanc; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Homotopy theory; Topological Data Analysis; Category theory; Mapping spaces; Homotopy commutative diagrams; Matematik; Mathematics;

    Abstract : This thesis contains three papers. Paper A and Paper B deal with homotopy theory and Paper C deals with Topological Data Analysis. All three papers are written from a categorical point of view.In Paper A we construct categories of short hammocks and show that their weak homotopy type is that of mapping spaces. READ MORE

  6. 9. Energy system operation by Lagrangian relaxation

    Author : Erik Dotzauer; Andrew B. Philpott; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Due to its relatively high total energy efficiency, the application of cogeneration, i.e. simultaneous exploitation of power and heat from the energy transformation process, is receiving increased attention. In many countries cogeneration is today an essential element in the energy supply system. READ MORE

  7. 10. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Author : Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. READ MORE
