  1. 1. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development

    Författare :Anders Goude; Olov Ågren; Carlos Simão Ferreira; Uppsala universitet; []
    Nyckelord :Wind power; Marine current power; Vertical axis turbine; Wind farm; Channel flow; Simulations; Vortex model; Streamtube model; Control system; Graphics processing unit; CUDA; Fast multipole method; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. LÄS MER

  3. 2. Sustainable evolution of SMEs in response to socio-technical emergence

    Författare :Afifa Rahatulain; Mauro Onori; Dario Antonelli; KTH; []
    Nyckelord :knowledge management; organizational capability; socio-technical system; viable system model; Production Engineering; Industriell produktion;

    Sammanfattning : Technological advancements such as digitalization, cloud computing, and cyber-physical systems are transforming the present-day manufacturing industry. However, striving solely on the technological shift alone is insufficient to attain a sustainable competitive advantage. LÄS MER

  4. 3. 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. 4. An application of the decision-information-operation system model

    Författare :Darek M. Eriksson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Computer and Systems Science; Data och Systemvetenskap;

    Sammanfattning : The media provides frequent reports about organisations - both public and business - in crisis. These must re-organise themselves, often requiring the dismissal of employees in order to adapt to the emerging internal or external conditions. If they do not adapt, they do not survive. LÄS MER

  7. 5. Model Based Enhancement of Bioimpedance Spectroscopy Analysis : Towards Textile Enabled Applications

    Författare :Rubén Buendía López; Kaj Lindecrantz; Javier Rosell-Ferrer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physiological measurements; Bioimpedance; modelling; textiles;

    Sammanfattning : Several signal processing approaches have been developed to overcome the effect of stray capacitances in Electrical Bioimpedance Spectroscopy (EBIS) measurements. EBIS measurements obtained with textile-enabled instrumentation are more vulnerable to stray capacitances. LÄS MER
