  1. 21. Real Time Reachability Analysis for Marine Vessels

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sudakshin Ganesan; [2018]
    Keywords : Reachable set; Safety Verification; Marine dynamics; Machine Learning; Optimal control; Säkerhetsverifiering; nåbarhetsanalys; fartyg dynamisk;

    Abstract : Safety verification of continuous dynamical systems require the computationof the reachable set. The reachable set comprises those states the systemcan reach at a specific point in time. READ MORE

  3. 22. Experimental and numerical fluid-structure interaction analysis of a suspended rod subjected to forced vibrations

    University essay from KTH/Marina system

    Author : David Ahlsén; [2018]
    Keywords : ;

    Abstract : This study is evaluating Solid-Acoustic Finite Element modelling as a method for calculating structural vibration response in water. When designing for example vehicles, it is important to avoid vibrational resonance in any part of the structure, as this causes additional noise and reduced lifespan. READ MORE

  4. 23. Tip vortex cavitation and diffused vorticity of propeller profiles: a modelling approach : Investigation of an implemented TVI model, and  implementation and investigation of a DVH model

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Lukas Lundin; [2017]
    Keywords : Vortex dynamics; Cavitation; TVI; DVH; Von Kármán Vortex Street; Virveldynamik; Cavitering; TVI; DVH; Von Kármán virvelgata;

    Abstract : To predict fluid properties and interactions is an important task for the industry. It is plagued, however, by being close to impossible to predict analytically. Hence, it is customary to turn to numerical solutions. This in itself comes with many different methods and approaches suitable for different needs. READ MORE

  5. 24. Ocean Waves Estimation : An Artificial Intelligence Approach

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Andreas Ramberg; [2017]
    Keywords : Artificial Intelligence; Case-Based Reasoning; Encounter Angle; Encounter Spectrum; Feedforward Neural Network; Genetic Algorithm; Inverse Problem; Marine Vessels; Master Thesis; MATLAB; Model Parameter Estimation; Ocean Theory; Peak Period; Response Amplitude Operator; Ships; Significant Wave Height; Transfer Function; Wave Spectrum; Waves;

    Abstract : This thesis aims to solve the mathematical inverse problem of characterizing sea waves based on the responses obtained from a marine vessel sailing under certain sea conditions. By researching this problem the thesis contributes to the marine industry by improving products that are using ocean behavior for controlling ship's dynamics. READ MORE

  6. 25. Development of a Depth Controller for the SEAL Carrier

    University essay from KTH/Reglerteknik

    Author : Hannes Carlsson; [2017]
    Keywords : ;

    Abstract : The SEAL Carrier is a hybrid marine vessel capable of traveling both fast on the water surface and completely submerged.Due to the craft's hydrodynamical properties it is taxing on the pilots to keep the SEAL Carrier at a certain depth for longer periods of time, therefore it is desirable to have a depth controller.
