  2. 16. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

    Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

  4. 17. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

    Author : Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

    Abstract : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. READ MORE

  5. 18. LES stochastic modelling of cavitation with its applications in OpenFOAM

    Author : Boxiong Chen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rayleigh-Plesset Equation; Cavitation; Modelling; Simulation; Eulerian Stochastic Field Method; OpenFOAM; Homogeneous Equilibrium Model;

    Abstract : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.

    Abstract : This Ph.D. dissertation aimed at developing tools for the evaluation of ground response in borehole fields connected in parallel through modelling and monitoring studies. READ MORE

  7. 20. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

    Author : Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

    Abstract : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. READ MORE
