  1. 21. Modelling and simulations of window attachments for a surface warfare ship

    University essay from KTH/Flygdynamik

    Author : Mohammad Mekdadi; [2020]
    Keywords : ;

    Abstract : In recent years it has been discovered that the window installations on the Visby class corvette are prone to break. The aim of this report is to perform a structural analysis of three different windowinstallations. READ MORE

  3. 22. Deep Learning Approach to Material Properties

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Love Pettersson; [2020]
    Keywords : Artificial Neural Networks; ANN; Deep learning; Density functional theory; DFT; Perovskites; Machine learining; Science General;

    Abstract : In this thesis, we consider a deep learning approach to predict material properties. Primarily we study artificial neural networks (ANN), which predict the energy distance to the convex hull (measure of stability) of perovskites. Further, we explore if the networks can be generalised to predict band gaps and unit cell volume. READ MORE

  4. 23. Investigating strains on the Oseberg ship using photogrammetry and finite element modeling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Andreas Eriksson; Erik Thermaenius; [2020]
    Keywords : Oseberg ship; strain; strain analysis; mechano-sorptive strains; Delaunay triangulation; finite element analysis;

    Abstract : The Oseberg ship is known as one of the finest surviving artifacts from the Viking age, with origins dated back to the 800s. The ship has been displayed in the Viking ship museum in Oslo since 1926. The nearly 100 years on museum display along with the over 1000 years it was buried has weakened the structure of the ship.

  5. 24. Strength assessment of rig foundations for a sailing car carrier

    University essay from KTH/Lättkonstruktioner

    Author : Alfred Rapaport; [2020]
    Keywords : Naval Architecture; Solid Mechanics; Finite Element Analysis; Concept development; Sailing; Skeppsbyggnad; Hållfasthetslära; Finita elementmetoden; Konceptutveckling; Segling;

    Abstract : The wPCC project (wind powered car carrier) is carried out by Wallenius Marine, KTH Royal Institute of Technology and SSPA Sweden. By developing a car carrier mainly propelled by the wind, the emissions are estimated to be reduced by up to 90 %. This thesis deals with the structural aspects of the design. READ MORE

  6. 25. Generation of a full-envelope hydrodynamic database for hydrobatic AUVs : Combining numerical, semi-empirical methods to calculate AUV hydrodynamic coefficients

    University essay from KTH/Marina system

    Author : Tianlei Miao; [2019]
    Keywords : AUV; hydrodynamic coefficients; database; Jorgensen method; DATCOM method; CFD; Simulink simulator; data confidence level;

    Abstract : The next generation of Autonomous Underwater Vehicles (AUV) can impact our observation of the world. The flight simulation and full-envelope hydrodynamics modeling can improve the performance of AUVs in terms of control, navigation and positioning. READ MORE
