  1. 6. Energy Efficiency in Machine Learning : Approaches to Sustainable Data Stream Mining

    Författare :Eva García Martín; Håkan Grahn; Veselka Boeva; Emiliano Casalicchio; Jesse Read; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine learning; energy efficiency; data stream mining; green machine learning; edge computing; Computer Science; Datavetenskap;

    Sammanfattning : Energy efficiency in machine learning explores how to build machine learning algorithms and models with low computational and power requirements. Although energy consumption is starting to gain interest in the field of machine learning, still the majority of solutions focus on obtaining the highest predictive accuracy, without a clear focus on sustainability.

  3. 7. Low consistency refining of mechanical pulp : process conditions and energy efficiency

    Författare :Stefan Andersson; Per Engstrand; Christer Sandberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical pulping; low consistency refining; energy efficiency; rotor position; plate gap; fibre concentration;

    Sammanfattning : The thesis is focussed on low consistency (LC) refining of mechanical pulp. Theresearch included evaluations of energy efficiency, development of pulpproperties, the influence of fibre concentration on LC refining and effects of rotorposition in a two-zoned LC refiner. LÄS MER

  4. 8. Perspectives on Demand Side Energy Efficiency

    Författare :Olof Björkqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transaction cost; energy efficiency; energy conservation; viable system model; Markal; demand-side management; local energy planning; organisational cybernetics; reference energy system; decision support; case study;

    Sammanfattning : This work treats recommendations based on energy systems engineering. The focus is on what can be learned by different methods about the roles that demand-side energy efficiency should play in the energy system. LÄS MER

  5. 9. Energy Efficiency Improvements of Tumble Dryers : -Technical Development, Laundry Habits and Energy Labelling

    Författare :Lena Stawreberg; Lars Nilsson; Jonas Berghel; Roger Renström; Björn Palm; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; Thermal energy engineering; Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. LÄS MER

  7. 10. Challenges for end-use energy efficiency

    Författare :Frances Sprei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; technological development; Swedish building sector; downsizing; Energy efficiency; fuel consumption; market barriers;

    Sammanfattning : The scientific community has reached close to a consensus that anthropogenic emissions of greenhouse gases are causing a change of the global climate. These emissions arise foremost from the burning of fossil fuels, and secondly from land use change. LÄS MER
