UAV Path Planning for Maximum-Information Sensing in Spatiotemporal Data Acquisition
(Master thesis, 2017)Fixed-wing Unmanned Aerial Vehicles are extensively used for ground observation, as they allow for effective and precise methods of collecting information. They do however, have a downside as the quality of the information ... -
UAV path planning using MILP with experiments
(Journal article; Peer reviewed, 2017)In this paper, we look at the problem of tracking icebergs using multiple Unmanned Aerial Vehicles (UAVs). Our solutions use combinatorial optimization for UAV path planning by formulating a mixed integer linear programing ... -
UAV/UAS path planning for ice management information gathering
(Master thesis, 2011)The key objective of this work is the proposition of the path planning strategy for unmanned aerial vehicle (UAV) intended for information gathering in Arctic environments / ice-infested regions. Two different path planning ... -
Ultra-Wide Band Real Time Location Systems: Practical Implementation and Performance Evaluation
(Chapter, 2017)Several different methods can be used to determine the 3-dimensional position of an object. A common solution is use of Global Navigation Satellite System (GNSS). However, for some operation the specific characteristics ... -
Ultra-wideband Aided Inertial Navigation of an Indoor Robot
(Master thesis, 2020)Abstract will be available on 2023-07-06 -
Ultrasound Based Localization and Quantification of Skeletal Muscle Contraction
(Master thesis, 2014)Earlier experiments indicates that motor unit activity during isometric contractions can be imaged using a high-definition ultrasound scanner. In this study, ultrasound raw-data is analysed in MATLAB to localize and quantify ... -
Ultrasound Radiation Force for Increased Transport of Drugs in Cancer Tumors
(Master thesis, 2014)Cancer is today one of the leading causes of death world wide. Chemotherapy is a cancer treatment where cytotoxic drugs are administered intravenously in order to kill the cancer cells. This is a therapy form which is ... -
Ultrasound speckle reduction using generative adversial networks
(Journal article; Peer reviewed, 2018)Generative adversial networks (GANs) have shown its ability to create realistic and accurate image-to-image transformation. The goal of this work was to investigate whether deep convolutional GANs can learn to perform ... -
Ultrasound Strain Rate Imaging of Individual Muscle Motor Units
(Journal article; Peer reviewed, 2014)Skeletal muscle is organized in motor units, each comprising a motor neuron and all its connected muscle fibres. The arrival of an action potential (a neural “impulse”) causes the fibers to contract, they exhibit a twitch. ... -
Ultrasound View Detection
(Master thesis, 2010)The goal of this project is to establish effective ultrasound view detection between apical, parasternal long axis and parasternal short axis view. The chosen approach in this project is to represent a shape of the cavity ... -
Una moneda supranacional en el espíritu de Keynes: China (con Rusia y América Latina) podría crear un mejor sistema financiero internacional
(Journal article; Peer reviewed, 2021)Este breve artículo argumenta a favor de la implementación de una unión de compensación internacional y una nueva moneda internacional en la línea del bancor propuesto por Keynes. Desde la perspectiva de los sistemas de ... -
Uncertainty estimation in autoregressive exogenous networks and nonlinear autoregressive exogenous neural networks
(Master thesis, 2021)Autoregressive eksogene (ARX) nettverk og ikke-lineære autoregressive eksogene (NARX) nevrale nettverk er avhengige av et mål på usikkerhet hvis de skal brukes til sikkerhets kritiske oppgaver, der feil valg i det verste ... -
Uncertainty Estimation in Image Classification as a Step Toward Autonomous Inspection
(Master thesis, 2023)DNVs REDHUS prosjekt har som mål å utvikle autonom deteksjon og klassifikasjon av defekter inni ballasttanker på skip ved hjelp av maskinlæringsalgoritmer. Hvis deteksjons- og klassifikasjonsalgoritmer skal stoles på er ... -
Uncertainty Estimation in Neural Networks
(Master thesis, 2022)Denne masterrapporten vil se på metoder for usikkerhetsestimering av nevrale nettverk. For å begrense omfanget er bruksområdet for disse nevrale nettverkene landbaserte prosessindustrier. Hovedfokuset vil være usikkerheten ... -
Uncertainty in Hyperspectral Remote Sensing: An Evaluation in Forest Monitoring
(Master thesis, 2023)Hyperspektral data gjør det mulig å overvåke jordens tilstand, og åpner dermed for bruksområder innen maskinlæringsmodeller. Likevel kan usikkerhet i data og modeller føre til feilaktige konklusjoner og fatale konsekvenser ... -
Uncertainty Management in a Scenario-Based MPC for Collision Avoidance
(Master thesis, 2019)Eit robust antikollisjonssystem er viktig for å sørge for sikker styring av autonome overflatefartøy. Dette antikollisjonssystemet er avhengig av eit påliteleg målfølgingssystem for å halde styr på hindringar i nærleiken. ... -
Uncertainty-Aware Visually-Attentive Navigation Using Deep Neural Networks
(Peer reviewed; Journal article, 2023)Autonomous navigation and information gathering in challenging environments are demanding since the robot’s sensors may be susceptible to non-negligible noise, its localization and mapping may be subject to significant ... -
Under the sea: How can we use heart rate and accelerometers to remotely assess fish welfare in salmon aquaculture?
(Peer reviewed; Journal article, 2023)Recent advances in bio-sensing technologies open for new possibilities to monitor and safeguard the welfare of fishes in aquaculture. Yet before taken into practice, the applicability of all novel biosensors must be ... -
Underactuated leader-follower synchronisation for multi-agent systems with rejection of unknown disturbances
(Journal article, 2015)In this paper leader-follower synchronization is considered for underactuated followers in an inhomogeneous multi-agent system. The goal is to synchronise the motion of a leader and an underactuated follower. Measurements ... -
