  1. 1. Robust light source detection for AUV docking

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

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

    Abstract : 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. READ MORE

  2. 2. Propulsion modelling of a generic submarine propeller

    University essay from KTH/Skolan för teknikvetenskap (SCI)

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Centrum för öst- och sydöstasienstudier

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

    Abstract : 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. READ MORE

  4. 4. Blind Acoustic Feedback Cancellation for an AUV

    University essay from Linköpings universitet/Reglerteknik

    Author : Hampus Frick; [2023]
    Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

  5. 5. Fighting for Sustainability: A Case Study about Tenerife's Activism Movement

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Felicitas Brodtrager; [2023]
    Keywords : Sustainable destination development; activism; tourism impacts; stakeholder involvement; sustainability; alternative tourism model; system thinking; doughnut economics;

    Abstract : This research explores the perspectives of the opinion leaders of the activism movement in Tenerife on tourism on the island and the solutions proposed by these stakeholders to the current sustainability problems related to tourism. These issues include tourist's misbehavior in natural protected areas, waste, submarine emissions of residual water sewage, water shortage, gentrification, overtourism, overpopulation, 14,6% of unemployment in 2022, decline of agricultural land, high population density, etc. READ MORE
