  1. 1. Utveckling av ett verktyg för konstruktion och optimering av små farkoster

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Marcus Näslund; [2018]
    Nyckelord :;

    Sammanfattning : It is very beneficial to minimize the weight of a ship as much as possible in order to reduce fuel costs. The weight depends a lot on the structural arrangment, which makes it the ship designers job to keep it lightweight. Design tools today are specialized for large ships and are expensive to use.

  3. 2. Ocean Waves Estimation : An Artificial Intelligence Approach

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Andreas Ramberg; [2017]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Optimization of the hull shape of a specialized vessel used to deploy wave energy converters

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Elektricitetslära

    Författare :Simon Larsson; [2016]
    Nyckelord :Hydrostatic stability; Stability; Specialized vessel; Deployment of wave Energy Converters; Deployment; Solidworks; Ansys Aqwa; Structural analysis; Stability analysis; Optimization;

    Sammanfattning : In this study, the initial hydrostatic stability, the hydrostatic stability and the structure realibility of three different barge-shaped vessels is simulated and evaluated in order to see which of the vessels would be the most optimal to use for deployment of wave energy converters, WECs. The vessels differ in their hull type: Bulbous-bow hull vessel, Barge hull vessel and Modified-barge hull vessel. LÄS MER

  7. 5. Regulation of endothelial inflammation by TAM receptors

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Oktawia Wolanin; [2015]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The TAM (Tyro3, Axl, Mer) receptors tyrosine kinases together with their ligands Gas6 and protein S play an important role in many cellular processes such as resolution of inflammation and phagocytosis. Notably, they were found to have an important function in vasculature, acting as a pro-survival factors and regulators of angiogenesis. LÄS MER
