Ultra-Wideband Sensor-Communication
(Master thesis, 2008)One of the fundamentals concerns in wireless communications with battery operated terminals is the battery life. Basically there are two ways of reducing power consumption: the algorithms should be simple and efficiently ... -
Ultrabredbåndsoverføring av medisinske bilder
(Master thesis, 2007)I forbindelse med overføring av bilder i sensornettverk, er det ønskelig at den totale effektforbruken minimeres for å sikre lang levetid på batteridrevne sensorer. Ved bildekomprimering vil denne effektbruken være avhengig ... -
Ultrafast Optical and Magneto-Optical Kerr Effect Spectroscopy on Condensed Matter
(Master thesis, 2017)In this masters project, an ultrafast optical spectroscopy system has been constructed and tested. The system was built as an extension to an existing spectroscopy system, centered around a mode-locked Ti:Sapphire femtosecond ... -
Ultrafast Spectroscopic Studies of Ferroelectric BaTiO3 Thin-Films on SrTiO3
(Master thesis, 2016)In this masters thesis ultrafast spectroscopic studies have been performed on single-crystal 111 strontium titanate, SrTiO3, and pulsed-laser deposited (PLD) thin-films of ferroelectric barium titante, BaTiO3. This has ... -
Ultrasonic focusing through a steel layer for acoustic imaging
(Journal article; Peer reviewed, 2018)Ultrasonic tools are being used for imaging in a large variety of fields, spanning from medical applications in a hospital to applications deep down in oil and gas wells. When applying ultrasonic imaging techniques to image ... -
Ultrasonic Imaging through Solids
(Master thesis, 2016)Ultrasonic testing is a widely used method, in the industry, for non destructive inspection of materials. The most commonly used technique is the pulse-echo technique where ultrasound is introduced into a test object and ... -
Ultrasound Contrast Imaging - Improved Tissue Suppression in Amplitude Modulation
(Master thesis, 2006)The ability to image myocardial perfusion is very important in order to detect coronary diseases. GE Vingmed Ultrasound uses contrast agent in combination with a pulse inversion (PI) technique to do the imaging. But this ... -

Ultrasound Examination of Steel Pipes
(Master thesis, 2007)Non-intrusive testing of pipelines has become a growing industry, and is expected to keep growing as the demands on quality control and safety keep increasing. In order to meet the oil industry s demands for pipe monitoring ... -
Ultrasound image processing using deep generative models
(Master thesis, 2020)Speckle er blant de mest forstyrrende elementene i medisinske ultralydbilder. Fenomenet forvrenger signalet som legene ønsker å undersøke og gjør det vanskeligere å oppdage små somatiske anomalier. Dette prosjektet søker ... -
Ultraviolet Optoelectronic Devices Based on GaN/AlGaN Nanowires Grown on Graphene Substrates
(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 ... -
