  1. 21. Att elda för kråkorna? : hushållens energianvändning inom bostadssektorn i Sverige 1913-2008

    Författare :Mikael Levin; Magnus Lindmark; Ann-Kristin Bergquist; Astrid Kander; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic History; households; energy consumption; consumption patterns; housing; housing and energy policy; carbon dioxide emissions; Ekonomisk historia; hushåll; energikonsumtion; konsumtionsmönster; hushåll och energipolitik; koldioxidutsläpp; ekonomisk historia; Economic History;

    Sammanfattning : This thesis investigates the development of the long-term energy consumption in the Swedish households by estimating the sector’s total energy use and moreover, by examining how structural, institutional and economic factors have affected the demand for energy in the residential sector during the period 1913-2008. The investigated period covers a transition from traditional fuels, such as firewood, to fossil fuels and finally renewable energy. LÄS MER

  3. 22. Energy Reduction of Robot Stations with Uncertainties

    Författare :Mattias Hovgard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robot station; Stochastic uncertainties; Energy optimization; Industrial robot;

    Sammanfattning : This thesis aims to present a practical approach to reducing the energy use of industrial robot stations. The starting point of this work is different types of robot stations and production systems found in the automotive industry, such as welding stations and human-robot collaborative stations, and the aim is to find and verify methods of reducing the energy use in such systems.

  4. 23. Measurement, Modeling, and Characterization for Energy-Efficient Computing

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

    Sammanfattning : 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.

  5. 24. Essays on inheritance, small businesses and energy consumption

    Författare :Sebastian Escobar; Mikael Elinder; Katarina Nordblom; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; estates; bequests; inheritance taxes; tax evasion; tax avoidace; liquidity; entrepreneurship; small business; sub-metering; environment; smart meters; energy conservation; quasi experiment;

    Sammanfattning : Essay 1: People’s planning to evade the inheritance tax curtails its merits. However, the extent of planning remains a matter of argument. According to popular belief, it is widespread, but few estimates have been presented. LÄS MER

  7. 25. Energy Transfer and Conversion in the Magnetosphere-Ionosphere System

    Författare :Lisa Rosenqvist; Stephan Buchert; Andris Vaivads; Mike Lockwood; Uppsala universitet; []
    Nyckelord :Space and plasma physics; solar system; space physics; magnetospheric physics; plasma physics; magnetic storms; substorms; boundary layers; magnetic reconnection; energy conversion; space weather; Rymd- och plasmafysik;

    Sammanfattning : Magnetized planets, such as Earth, are strongly influenced by the solar wind. The Sun is very dynamic, releasing varying amounts of energy, resulting in a fluctuating energy and momentum exchange between the solar wind and planetary magnetospheres. LÄS MER
