  1. 1. Den svenska underrättelseapparaten i kris: En studie av Sveriges underrättelseverksamhet i samband med ubåtsfrågan och tsunamikatastrofen

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Olof Svarén; [2024]
    Nyckelord :Sverige; Underrättelseverksamhet; Kris; Ubåtsfrågan; Tsunamikatastrofen; Law and Political Science;

    Sammanfattning : Drawing upon previous studies in the fields of organisational theory and intelligence failure, this paper examines the efforts of the Swedish intelligence community in connection to two major crises: the submarine issue of the 1980s and early 1990s as well as the tsunami disaster of 2004. Firstly, when studying its performance in both instances, the paper finds that the intelligence community failed to meet the needs of critical decision makers during both crises. LÄS MER

  2. 2. Robust light source detection for AUV docking

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joar Edlund; [2023]
    Nyckelord :Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

    Sammanfattning : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. LÄS MER

  3. 3. U_Bot : Konstruktionen av en trådlös fjärrstyrd utbåt

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jonatan Mauritz; William Granat; [2023]
    Nyckelord :Mechatronic; KTH; Submarine; Underwater; Arduino; Hand Control; Wireless; Mekatronik; KTH; Ubåt; Under Vatten; Arduino; Handkontroller; Trådlös;

    Sammanfattning : Abstract The goal of this project was to design a submarine that could be operated using a wireless game controller. To accomplish this, we used an Playknowlogy board connected to a USB-Host Shield that recieves signals from the game controller and sends them to a USB connected to the USB-Host Shield. LÄS MER

  4. 4. Propulsion modelling of a generic submarine propeller

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gustav Boman; [2023]
    Nyckelord :OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

    Sammanfattning : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. LÄS MER

  5. 5. Navigating narratives: A framing analysis of AUKUS in Chinese state media

    Master-uppsats, Lunds universitet/Centrum för öst- och sydöstasienstudier

    Författare :Alison Clark; [2023]
    Nyckelord :AUKUS; Trilateral security collaboration; Chinese state media; Media framing; Social Sciences;

    Sammanfattning : This thesis investigates how the framing of AUKUS, a trilateral security and defense collaboration consisting of Australia, United Kingdom, and the United States, is portrayed by Chinese state media. AUKUS, established on September 15, 2021, is mainly focusing on providing Australia with nuclear-powered submarine technology. LÄS MER
