    Författare :Johan Bladh; Urban Lundin; Rafael Escarela-Perez; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amortisseur windings; applied voltage test; automatic voltage regulators; damper windings; damping torque; empirical modelling; equivalent circuits; excitation control; finite element method; hydropower generators; power system restoration; power system stability; synchronous machines; self excitation; shaft torque amplification; short circuit test; single machine infinite bus; slip test; standstill frequency response test; subsynchronous oscillations; synchronising torque; synchronous generators; torsional interaction.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : After decades of routine operation, the hydropower industry faces new challenges. Large-scale integration of other renewable sources of generation in the power system accentuates the role of hydropower as a regulating resource. LÄS MER

  2. 12. A reactive approach to component-based design of resource-constrained embedded systems

    Författare :Jimmie Wiklander; Luleå tekniska universitet; []

    Sammanfattning : Embedded systems have become commonplace in today's society and the number of functions and their complexity are steadily increasing. This can be attributed to the advances in the microprocessor technology and the continuous development of more powerful and power-efficient microprocessors, which, in turn, allows more elaborate software implementations.

  3. 13. Energy Efficient Task Mapping and Resource Management on Multi-core Architectures

    Författare :Jing Chen; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Energy Consumption; Resource Management; Runtime; Dynamic Voltage-Frequency Scaling DVFS ; Predictive Models; Task Scheduling;

    Sammanfattning : Reducing energy consumption of parallel applications executing on chip multi- processors (CMPs) is important for green computing. Hardware vendors have been developing a variety of system features to support energy efficient computing, for example, integrating asymmetric core types on a single chip referred to as static asymmetry and supporting dynamic voltage and frequency scaling (DVFS) referred to as dynamic asymmetry.

  4. 14. Unlocking Potentials of Innovation Systems in Low Resource Settings

    Författare :Julius Ecuru; Blekinge Tekniska Högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cluster; Innovation; Innovation System; Low resource setting; Research; Science; Technology; Technoscience; Triple Helix; Uganda;

    Sammanfattning : This study examined the dynamics, challenges and opportunities of developing innovation systems in low resource settings with a particular focus on Uganda. It applied perspectives of technoscience and concepts of innovation systems, triple helix as university-industry-government relationships, mode 2 knowledge production and situated knowledges in understanding the context, identifying key policy issues and suggesting ways to address them.

  5. 15. Adaptive Design for Circular Business Models in the Automotive Manufacturing Industry

    Författare :Thomas Nyström; RISE; []
    Nyckelord :Circular Business Models; Product Service System; Business and Design Logic; Circular Economy; Design for Circular Business Models;

    Sammanfattning : The vision of a circular economy (CE) promises both profitability and eco-sustainability to industries, and can, from a material and energy resource flow perspective, be operationalized by combining three business and design strategies: closing loops; narrowing and slowing down resource flows by material recycling, improving resource efficiency; and by extending product life by reuse, upgrades and remanufacturing. These three strategies are straightforward ways for industries to radically reduce their use of virgin resources. LÄS MER
