2. 16. Algorithms and Framework for Energy Efficient Parallel Stream Computing on Many-Core Architectures

   Author : Nicolas Melot; Christoph Kessler; Joerg Keller; Jürgen Teich; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The rise of many-core processor architectures in the market answers to a constantly growing need of processing power to solve more and more challenging problems such as the ones in computing for big data. Fast computation is more and more limited by the very high power required and the management of the considerable heat produced. READ MORE

4. 17. Performance of High-temperature Coatings : Oxidation and Interdiffusion

   Author : Xiaoyu Sun; Ru Lin Peng; Johan Moverare; Xin-Hai Li; Lindwall Greta; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; diffusion; phase transformation; oxidation;

   Abstract : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. READ MORE

5. 18. Passive Island Detection of Microgrid by Grid Forming Inverter

   Author : Shoaib Salim Inamdar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microgrid; passive island detection; Grid forming; rotor angle deviation; non-detection zone; inertia; virtual synchronous machine; voltage vector shift.;

   Abstract : The supply reliability of a local grid will be improved if the local grid is managed as a microgrid, with the ability to operate in island mode when the main grid is temporarily unavailable. This thesis focuses on microgrids powered by inverter-based resources (IBRs), one or several of which need to be equipped with grid forming (GFM) capability for establishing and controlling the voltage and frequency of the microgrid during island operation.
