1. 1. Diving Deep: Seabird foraging tactics and local prey field

   Master-uppsats, SLU/Dept. Of Aquatic Resources

   Författare :Elin Andersson Sjöholm; [2024]
   Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

   Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER

3. 2. Data-Driven Adaptive Control of Unmanned Surface Vehicles Using Learning-Based Model Predictive Control

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Markus Svedberg; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. LÄS MER

4. 3. Development and Systems Integration of Small Hydrofoiling Robot for Mapping and Sensing

   M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

   Författare :Tommy Lopperi; Henrik Söderberg; [2022]
   Nyckelord :USV; Arduino; GNSS-navigation; Nvidia Xavier Nx Jetson; Systems integration; USV; Arduino; GNSS-navigation; Nvidia Xavier Nx Jetson; Systems integration;

   Sammanfattning : Unmanned surface vehicles (USVs) are vehicles of various levels of autonomy which can be made for a large variety of purposes, for instance ferriage and surveying. USV shave technically been around for about 80 years, however, it is only within fairly recent years developments in miniaturization of components and computers have allowed for the construction of USVs of a small size.

5. 4. Autonomous Docking of an Unmanned Surface Vehicle using Model Predictive Control

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Sofia Kockum; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Autonomous docking of marine vessels presents challenges different from the ones faced when travelling at open sea or in an archipelago. External disturbances due to the varying environment and accurate positioning at low speed are examples of these kinds of challenges. LÄS MER

7. 5. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Johan Elfing; Daniel Persson; [2022]
   Nyckelord :CatFish; Embedded System;

   Sammanfattning : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. LÄS MER
