Objective and subjective quality assessment of 360-degree images
(Doctoral theses at NTNU;2023:5, Doctoral thesis, 2023)360-degree images, a.k.a. omnidirectional images, are in the center of immersive media. With the increase in demands of the latter, mainly thanks to the offered interactive and immersive experience, it is paramount to ... -
Objective Beliefs and Bayes Estimators: An Approach to Parameter Estimation Using Objective Priors and Distance Between Distributions
(Master thesis, 2020)Denne oppgaven tar for seg problemet med å estimere parametre i statistisk analyse, og i særdeleshet Bayesiansk analyse. Gitt en modell utledes objektive a priori-fordelinger for parametrene. De resulterende fordelingene ... -
Objective evaluation of hearing loss simulators
(Master thesis, 2014)SINTEF s department in Trondheim, Norway, has developed a hearing loss simulator. Thepurpose of the simulator is to reconstruct hearing impaired s perception of sound. Thusfar, the simulator has only been judged subjectively, ... -
Objective evaluation of relighting models on translucent materials from multispectral RTI images
(Peer reviewed; Journal article, 2021)In this paper, we evaluate the quality of reconstruction i.e. relighting from images obtained by a newly developed multispectral reflectance transformation imaging (MS-RTI) system. The captured MS-RTI images are of objects ... -
Objective Image Quality Metrics for Ultrasound Imaging
(Master thesis, 2009)Objective evaluation of the image quality on ultrasound images is a comprehensive task due to the relatively low image quality compared to other imaging techniques. It is desirable to objectively determine the quality of ... -
Objective inference for correlation
(Master thesis, 2021)Denne masteroppgaven tar for seg problemstillingen om å hente mest mulig informasjon om korrelasjonen i en binormal fordeling basert på observerte punkter i planet. Forventningsverdiene og variansene er antatt kjente. Til ... -
Objekt identifisering
(Bachelor thesis, 2008)ETC har et system for administrasjon av bilparker som bl.a. benytter seg av elektronisk styrte nøkkelskap. Disse skapene har ingen måte å kontrollere om det er en nøkkel tilstede i et gitt nøkkelrom. Vi skal undersøke ... -
Objektiv og sansningsbasert vurdering av vindturbinstøy
(Master thesis, 2020)De fleste land benytter i dag regelverk for regulering av støyplage fra vindturbiner som er basert på lydtrykknivå, mens noen land bruker differensielle støygrenser som lydfremvekst. I denne sammenhengen har det blitt ... -
Oblique end face coupling optical fiber sensor for point fuel level measurement
(Peer reviewed; Journal article, 2019)A new implementation of point level sensor fabricated using the oblique multimode silica fibers is proposed and demonstrated. Based on Fresnel reflection, all the incident lights are reflected back by the oblique sensor ... -
Oblivious RAM in practice
(Master thesis, 2019)Målet med denne masteroppgaven er å studere ytelsen til nåværende Oblivious RAM (ORAM) løsninger og undersøke hvor praktiske de er i et skylagrings-scenario. For å gjøre dette ble tre ORAM løsninger (ObliviStore, CURIOUS ... -
Observable Effects of Selected Phasor Measurement Unit Time Delay Attacks
(Master thesis, 2023)Det tradisjonelle elektriske kraftnettet, som leverer elektrisk kraft til konsumenter, er i ferd med å bli transformert fra et system som er lukket og sentralstyrt et nettverksstyrt automatisert system for å levere elektrisk ... -
Observation-Resistant Multifactor Multimodal Authentication
(Master thesis, 2010)ENGELSK: This thesis investigates the use of hand gestures as an additional modality in authentication schemes, to thwart the risk of observation (shoulder surfing) attacks. We used the accelerometer already embedded in ... -
Observations and Reflections on Teaching Electrical and Computer Engineering Courses
(Chapter, 2018)In this article, we make a number of observations and reflections based on our experience from many years of teaching courses in electrical and computer engineering bachelor programmes. We present important aspects of ... -
Observer and IMU-based Detection of Faults in Position Reference Systems and Gyrocompasses with Dual Redundancy in Dynamic Positioning
(Journal article; Peer reviewed, 2014)Faults in position reference systems and vessel sensors pose a serious hazard during dynamic positioning, and vessel drive-offs because of erroneous data may have dire consequences. The classification society standards ... -
Observer Backstepping Control for Variable Speed Wind Turbine
(Chapter; Peer reviewed, 2013)This paper presents an observer backstepping controller as feasible solution to variable speed control of wind turbines to maximize wind power capture when operating between cut-in and rated wind speeds. The wind turbine ... -
Observer based path following for underactuated marine vessels in the presence of ocean currents: A global approach
(Journal article; Peer reviewed, 2019)In this paper a solution to the problem of following a curved path in the presence of a constant unknown ocean current disturbance is presented. We introduce a path variable that represents the curvilinear abscissa on the ... -
Observer Based Path Following for Underactuated Marine Vessels in the Presence of Ocean Currents: A Local Approach
(Journal article; Peer reviewed, 2017)In this article a solution to the problem of following a curved path in the presence of a constant unknown ocean current disturbance is presented. The path is parametrised by a path variable that is used to propagate a ... -
Observer Based Sliding Mode Attitude Control: Theoretical and Experimental Results
(Journal article; Peer reviewed, 2011)In this paper we present the design of a sliding mode controller for attitude control of spacecraft actuated by three orthogonal reaction wheels. The equilibrium of the closed loop system is proved to be asymptotically ... -
Observer Design for a Class of Semilinear Hyperbolic PDEs with Distributed Sensing and Parametric Uncertainties
(Peer reviewed; Journal article, 2022)We study a class of heterodirectional semilinear hyperbolic partial differential equations, where the distributed state vector is partially measured. An observer estimating the unmeasured part of the state vector is designed. ... -
