UAV Icing: Experimental validation data for predicting ice shapes at low Reynolds numbers
(Peer reviewed; Journal article, 2023) -
UAV Icing: Ice Accretion Experiments and Validation
(Journal article; Peer reviewed, 2019)Atmospheric icing is a key challenge to the operational envelope of medium-sized fixed-wing UAVs. Today, several numeric icing codes exist, that all have been developed for general aviation applications. UAVs with wingspans ... -
UAV Icing: Ice Shedding Detection Methods for an Electrothermal De-Icing System
(Chapter, 2022)Among the identified problems with unmanned aerial vehicles (UAVs), especially with the medium-sized fixed-wing UAVs, is a lack of mature ice protection systems (IPSs). One of the emerging UAV ice protection technologies ... -
UAV Icing: Icing Cases for Validation of Path Planning Method
(Peer reviewed; Journal article, 2023)As part of the complete solution to deal with atmospheric in-flight icing on unmanned aerial vehicles (UAV), a path planner is a valuable tool for finding an optimal path for accomplishing UAV missions. When considering ... -
UAV Icing: Intercycle Ice Effects on Aerodynamic Performance
(Peer reviewed; Journal article, 2023)Atmospheric in-flight icing poses a challenge to all aircraft including unmanned aerial vehicles (UAVs). Aircraft should avoid icing conditions unless they have ways of mitigating the negative effects of icing, e.g., if ... -
UAV Icing: Numerical Simulation of Icing Effects on Wing and Empennage
(Peer reviewed; Journal article, 2023)In-flight icing can result in severe aerodynamic performance penalties for unmanned aerial vehicles. It is therefore important to understand to which extent ice will build up on fixed-wing unmanned aerial vehicles wings ... -
UAV Icing: Validation of an Ice Protection System Design for a Propeller
(Chapter, 2024) -
UAV LiDAR in coastal environments: Archaeological case studies from Tierra del Fuego, Argentina, and Vega, Norway
(Peer reviewed; Journal article, 2023)LiDAR has become fairly integrated into archaeological practice at a global scale. This has gradually evolved to include UAV LiDAR. Nevertheless, considerable biases remain, including with regard to geographical regions, ... -
UAV net landing system for marine operations
(Master thesis, 2017)This thesis presents an automatic landing system designed for a fixed-wing unmanned aerial vehicle (UAV) to land in a net placed on ta ship. The UAV used is a Skywalker X8, a cheap and durable airframe, with a Pixhawk as ... -
UAV Path Planning for Ice Intelligence Purposes using NLP
(Master thesis, 2012)As the oil and shipping industry are interested in operating in arctic waters, the need for ice intelligence gathering is rising.The thesis describes the implentation and results of a path planning framework for an UAV ... -
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-Based Hyperspectral Stereoscopic Imaging for Accurate 3D Terrain Mapping
(Master thesis, 2022)Hyperspektral avbildning gir en ny dimensjon til den velutprøvde og mer tradisjonelle avbildningsteknikken stereoskopisk avbildning. Det presenterte arbeidet utforsker hvordan de komplementære avbildningsteknikkene ... -
UAV-den stygge andungen i moderne luftkrig. Hvordan ubemannede luftsystemer ble en del av det norske Forsvaret.
(Master thesis, 2016)Ubemannede flysystemer har i løpet av de siste årene blitt stadig mere aktuelt både i sivil og militær sammenheng. Spesielt tiden etter angrepet på USA i 2001 og den påfølgende globale krigen mot terror, førte til et stort ... -
UAV-enabled data acquisition scheme with directional wireless energy transfer for Internet of Things
(Peer reviewed; Journal article, 2020)Low power Internet of Things (IoT) is suffering from two limitations: battery-power limitation of IoT nodes and inflexibility of infrastructure-node deployment. In this paper, we propose an Unmanned Aerial Vehicle (UAV)-enabled ... -
UAV-enabled friendly jamming scheme to secure industrial Internet of Things
(Journal article; Peer reviewed, 2019)Eavesdropping is a critical threat to the security of industrial Internet of things (IIoT) since many malicious attacks often follow eavesdropping activities. In this paper, we present an anti-eavesdropping scheme based ... -
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 ... -
Uavhengig kontroll av brannsikkerhet - Fungerer uavhengig kontroll av brannsikkehet etter intensjonen den er tiltenkt?
(Master thesis, 2018)Uavhengig kontroll er noe som påvirker alle søknadspliktige byggeprosjekter i dag i større eller mindre grad. Intensjonen til uavhengig kontroll er å bidra til at det bygges med riktig kvalitet og å redusere byggfeil. ... -
Uavhengig kontroll i prosjektsammenheng
(Bachelor thesis, 2015)I Norge blir det hvert år gjort byggefeil for flere milliarder kroner. Slurv og dårlig håndverk koster ikke bare samfunnet unødvendig store summer, men kan også påvirke helse og sikkerhet for de som skal nytte seg av ...
