  1. 31. AUV SLAM constraint formation using side scan sonar

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

    Author : Marco Schouten; [2022]
    Keywords : AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Abstract : Autonomous underwater vehicle (AUV) navigation has been a challenging problem for a long time. Navigation is challenging due to the drift present in underwater environments and the lack of precise localisation systems such as GPS. Therefore, the uncertainty of the vehicle’s pose grows with the mission’s duration. READ MORE

  3. 32. Submap Correspondences for Bathymetric SLAM Using Deep Neural Networks

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

    Author : Jiarui Tan; [2022]
    Keywords : Underwater simultaneous localization and mapping; Multibeam echosounder; Point cloud registration; Deep learning; Undervattens simultan lokalisering och kartläggning; Multibeam ekolod; Punktmolnsregistrering; Djupinlärning;

    Abstract : Underwater navigation is a key technology for exploring the oceans and exploiting their resources. For autonomous underwater vehicles (AUVs) to explore the marine environment efficiently and securely, underwater simultaneous localization and mapping (SLAM) systems are often indispensable due to the lack of the global positioning system (GPS).

  4. 33. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    University essay from KTH/Teknisk mekanik

    Author : Martin Persson; [2022]
    Keywords : Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Abstract : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. READ MORE

  5. 34. Marine Habitat Mapping Using Image Enhancement Techniques & Machine Learning

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Mudasar Mureed; [2022]
    Keywords : Coral Reef; Habitat Mapping; Convolutional Neural Network; Transfer Learning; Fine Tuning; CLAHE;

    Abstract : AbstractThe mapping of habitats is the first step that is done in policies that target theenvironment, as well as in spatial planning and management. The biodiversityplans are always centered around habitats. Therefore, constant monitoring ofthese delicate species in terms of health, changes, and extinction is a must inbiodiversity plans.

  6. 35. It’s a Gas... Pipeline and Submarine Cable: A Study of the International Legal Framework Protecting Submarine Pipelines and Cables in the EEZ

    University essay from Lunds universitet/Juridiska fakulteten; Lunds universitet/Juridiska institutionen

    Author : Ludvig Nyhlén; [2022]
    Keywords : International law; folkrätt; Law and Political Science;

    Abstract : The legal protection of underwater pipelines and cables has never been more relevant. After the explosions in Nord Stream 1 and 2 that took place in the EEZ of both Denmark and Sweden, this protection was put in the limelight. READ MORE
