  1. 16. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    University essay from KTH/Betongbyggnad

    Author : Viktor Peterson; Zihao Wang; [2020]
    Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

    Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. READ MORE

  3. 17. Estimation of Inertia in Power Systems Using Electromechanical Modes

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Vidar Johnsson; [2020]
    Keywords : Technology and Engineering;

    Abstract : The transition to more renewable energy such as wind, leads to a decreased inertia in the power system. As a consequence of this, disturbances lead to larger frequency deviations and the frequency stability of the system is worsened. Therefore, there is a surging interest to estimate the inertia in the power system. READ MORE

  4. 18. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Marlon Luis Bause; [2020]
    Keywords : Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

    Abstract : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. READ MORE

  5. 19. Vibrational prediction of a waste water pump

    University essay from KTH/Hållfasthetslära

    Author : Daniel Sundström; [2020]
    Keywords : ;

    Abstract : An off-market waste water pump is suspected to have high vibrational velocity levels. These vibrations are sought after at the outer surface located at the upper bearing position of the pump. It has then become of interest for trying to predict these vibrations by using the commercial FEA software COMSOL. READ MORE

  6. 20. Expansion of Existing Gravity-Based Offshore Wind Turbine Foundations

    University essay from KTH/Betongbyggnad

    Author : Álvaro Hernando Cabrero; [2020]
    Keywords : Gravity-Based Foundation; climate actions; expansion; failure mode; width; Lillgrund;

    Abstract : Wind energy is one of the most promising sources of renewable energy worldwide. Its utilization has substantially increased for the last decades, both onshore and offshore. Offshore wind energy will have a lot to offer within the following decades, thus their foundations need to be prepared. READ MORE
