(Master thesis, 2020)Dioder av gruppe III-nitrid halvledermateriale har utstrakte anvendelser innen den synlige delen av det elektromagnetiske spekteret. Feltet som omhandler bruken av ultrafiolette optoelektroniske komponenter er mindre modent, ... -
Uncovering Patterns in Teleconference Call Data: An Analysis using Clustering Method
(Master thesis, 2023)Videokonferanser har blitt en integrert del av vår kommunikasjonslandskap, spesielt i sammenheng med fjernarbeid og virtuelle samarbeid. Behovet for å undersøke lyd- og videokvaliteten i videokonferansesamtaler har blitt ... -
Understanding ocean acoustics by eigenray analysis
(Journal article; Peer reviewed, 2019)Acoustics is important for all underwater systems for object detection, classification, surveillance systems, and communication. However, underwater acoustics is often difficult to understand, and even the most carefully ... -
Undersøkelse av bevegelsesmønsteret til en oseanografisk bøye ved hjelp av Kalmanfiltrering
(Master thesis, 2009)Hensikten med denne oppgaven har vært å lage et Kalmanlter for beregning av tilstandsvektoren til en osceanogrask bøye. Under arbeidet har det blitt brukt kjente bølgedata for simulering og for å kontrollere og sammenligne ... -
Undervannsovervåking ved hjelp av fiberoptisk hydrofon: Underwater surveillance using a fiber optic hydrophone
(Master thesis, 2014)Since the 1970s fiber optics has been introduced as a replacement in many industrial areas, especially in the field of communications. Another field which has been and is greatly researched is the use of fiber optic cables ... -
Underwater Communications: An OFDM-system for Underwater Communications
(Master thesis, 2007)In the fall 2006 NTNU (The Norwegian University and Science and Technology) initiated a strategic project in cooperations with SINTEF where the aim is to gain more knowledge about underwater acoustic communications. This ... -
Underwater Radio Communication
(Master thesis, 2013)In subsea applications, there is a growing demand for high-speed wireless communication links for transmitting data between different equipment. Radio communication is constrained by the high attenuation in seawater. Only ... -

Uniaxial Néel vector control in perovskite oxide thin films by anisotropic strain engineering
(Peer reviewed; Journal article, 2021)Antiferromagnetic (AF) thin films typically exhibit a multidomain state, and control of the AF Néel vector is challenging, as AF materials are robust to magnetic perturbations. In this paper, uniaxial Néel vector control ... -
Universal Programmable State Machine
(Master thesis, 2019)Tilstandsmaskiner (FSM-er) blir utstrakt brukt i digital maskinvaredesign. Ettersom markedet for integrerte kretser og brikke-systemer er økende m ̊a designene følge etter. FSM-er blir ofte spesiallaget og hardkodet for ... -
Unsupervised Anomaly Detection for IoT-Based Multivariate Time Series: Existing Solutions, Performance Analysis and Future Directions
(Peer reviewed; Journal article, 2023)The recent wave of digitalization is characterized by the widespread deployment of sensors in many different environments, e.g., multi-sensor systems represent a critical enabling technology towards full autonomy in ... -
Unsupervised machine learning applied to scanning precession electron diffraction data
(Journal article; Peer reviewed, 2019)Scanning precession electron diffraction involves the acquisition of a two-dimensional precession electron diffraction pattern at every probe position in a two-dimensional scan. The data typically comprise many more ... -
Up- and downgoing borehole wavefield retrieval using single component borehole and reflection data
(Journal article; Peer reviewed, 2018)A standard procedure in processing vertical seismic profile (VSP) data is the separation of up- and downgoing wavefields. We show that these wavefields in boreholes can be retrieved using only single-component data, given ... -
