Enhetlig visjonsbasert autonom navigasjon for roboter
(Master thesis, 2015)Motivasjonen til denne avhandlinga er å undersøke bruken av eit kamera som sensor for autonome bakkerobotar. Noverande autonome system nyttar som regel optisk fjernmålingsteknikkar som lidar, i tillegg til GPS-posisjonering. ... -
Ensemble Kalman Filtering for State and Parameter Estimation on a Reservoir Model
(Master thesis, 2007)In reservoir management it is important with reservoir models that have good predictive abilities. Since the models initially are based on measurements with high uncertainties it is important to utilize new available data. ... -
An ensemble modelling approach for spatiotemporally explicit estimation of fish distributions using data assimilation
(Journal article; Peer reviewed, 2023)This article presents a novel method for estimating large scale spatiotemporal distribution patterns of fish populations modelled at the individual level. A single realization of an individual-based model calibrated on ... -
An environmental disturbance observer framework for autonomous surface vessels
(Peer reviewed; Journal article, 2023)This paper proposes a robust disturbance observer framework for maritime autonomous surface vessels considering model and measurement uncertainties. The core contribution lies in a nonlinear disturbance observer, reconstructing ... -
EPP-basert protesemodell
(Master thesis, 2011)Oppgaven er en fortsettelse av tidligere arbeid med å utvikle en EPPbasertprotsese med to frihetsgrader til en ung dysmelipasient som hartransversell armdysmeli med en rudimenter nger. Denne ngeren skalbrukes til å styre ... -
Error Detection and Correction for Low-Cost Nano Satellites
(Master thesis, 2013)The objective of this paper is to suggest low-cost measures for dependability and robust Error Detection and Correction for use in applications such as nano satellites, where price is a primary concern. Different methods ... -

Estimating Glucose Appearance Rate in Blood After Meal Digestion using Sequential Machine Learning
(Master thesis, 2022)Diabetes mellitus er en sykdom der kroppens evne til å regulere glukosenivået blir hemmet av manglende insulinproduksjon i bukspyttkjertelen. Det finnes per dags dato ingen kur for denne sykdommen, men flere utforsker ... -
Estimating vector magnitude from its direction and derivative, with application to bearing-only SLAM filter problem
(Journal article; Peer reviewed, 2019)For some problems, such as monocular visual odometry (VO), vector measurements are given with unknown magnitude. In VO, the magnitude can be found by recognizing features with known position, or with an extra sensor such ... -
Estimation and Prediction of Glucose Appearance Rate for Use in a Fully Closed-Loop Dual-Hormone Intraperitoneal Artificial Pancreas
(Peer reviewed; Journal article, 2023)Objective: A fully automated artificial pancreas requires a meal estimator and predictions of blood glucose levels (BGL) to handle disturbances during meal times, all without relying on manual meal announcements and user ... -
Estimation in Large Mechanistic Models
(Master thesis, 2011)The main objective in this thesis is to model an offshore processing plant, and adapt it to a given dataset by off-line parameter estimation and then perform an on-line state and parameter estimation. The aim is to use the ... -
Estimation in nonlinear constrained systems with severe disturbances
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:261, Doctoral thesis, 2008)Aluminium is a metal playing an important role in all modern life of today, and it will continue to play an important role in many years to come. As with every business and everyone who participates in the global economy, ... -
Estimation in uncertain switched systems using a bank of interval observers: local vs glocal approach
(Peer reviewed; Journal article, 2021)This paper discusses some issues related with the design of a bank of interval observers for uncertain switched systems, in which several sources of uncertainty are considered: parametric uncertainties, unknown disturbances, ... -
Estimation of Angle of Attack and Sideslip Angle applied in an Airborne Wind Energy System
(Master thesis, 2019)Hovedbidraget i denne oppgaven er implementasjon og anvendelse av en metode for estimering av angrepsvinkler for ubemannede luftfartøy - anvendt på teknologi for utnyttelse av høydevindkraft. Den implementerte metoden er ... -
Estimation of Bottomhole Pressure for Managed Pressure Drilling: Comparison of Nonlinear Estimators
(Master thesis, 2011)To avoid hole stability problems in an increasingly fierce drilling environment, the demand for accurate control of the pressure profile during drilling operations is rising. As standard instrumentation of drilling rigs ... -
Estimation of fish catch potential using assimilation of synthetic measurements with an individual-based model
(Journal article; Peer reviewed, 2023)A large fraction of costs in wild fisheries are fuel related, and while much of the costs are related to gear used and stock targeted, search for fishing grounds also contributes to fuel costs. Lack of knowledge on the ... -
Estimation of Formation Water rate using Unscented Kalman filtering with application to the Snøhvit Gas/Condensate Field.
(Master thesis, 2013)In this thesis, a simplified model of the MEG loop at the Snøhvit field is established and implemented, together with an unscented Kalman filter. The model is tested with and without the Kalman filter. The model is tested ... -
Estimation of glucose rate of appearance in portal vein circulation using a phenomenological-based model
(Peer reviewed; Journal article, 2023)The joint work of the stomach and the small intestine plays a fundamental role in human digestion. In the stomach, food is turned into a semi-fluid mixture that is slowly released into the small intestine, where most ... -
