Early Detection of Cerebral Palsy Using Two Computer-Based Methods
(Master thesis, 2016)In this master thesis the assignment was to perform a statistical analysis of two different computer-based methods, to see which one that had the highest predictive ability for fidgety movements in infants. One method has ... -
Early Meal Detection Based on Abdominal Sound
(Master thesis, 2019)Denne oppgaven beskriver utvikling og implementasjon av en algoritme for måltidsdeteksjon basert på lyd fra magen. Målet er at en slik algoritme skal være en del av en automatisk insulinpumpe, også kalt en kunstig ... -
Early pack-off diagnosis in drilling using an adaptive observer and statistical change detection
(Journal article, 2015)Pack-off is a partially or complete blocking of the circulation flow in oil and gas drilling, which can lead to costly delays. Early detection and localization of a pack-off is crucial in order to take necessary actions ... -
ECG augmented pulse oximetry in Atlantic salmon (Salmo salar)—A pilot study
(Peer reviewed; Journal article, 2023)Understanding the tolerance limits of fish is crucial for developing aquaculture operations that ensure good animal welfare. However, there exist little data describing the physiological responses in farmed Atlantic salmon, ... -
Echo State Network Based Inverse Models for Feedforward Assisted Optimal Control of Electric Submersible Pumps
(Master thesis, 2023)Håndtering av forstyrrelser er antakelig en av de viktigste, men også mest utfordrende, områdene innen reguleringsteknikk. Til tross for at det finnes uttalelige metoder, samt store mengder teori på hvordan forstyrrelser ... -
Echo State Networks for data-driven downhole pressure estimation in gas-lift oil wells
(Journal article; Peer reviewed, 2017)Process measurements are of vital importance for monitoring and control of industrial plants. When we consider offshore oil production platforms, wells that require gas-lift technology to yield oil production from low ... -
Echo State Networks for Virtual Flow Metering in Gravity Separator
(Master thesis, 2019)Virtuell volumstrøm estimering (Virtual Flow Metering, VFM), er et begrep som innebærer å estimere volumraten for de ulike fasene i en fler-fase volumstrøm uten å måle de direkte. Istedenfor så brukes data som er relatert ... -
Economic and Multi-objective Model Predicitve Control
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:179, Doctoral thesis, 2014) -
Economic model predictive control for snake robot locomotion
(Journal article; Peer reviewed, 2019)Abstract— In this work, the control of snake robot loco-motion via economic model predictive control (MPC) is studied.Only very few examples of applications of MPC to snake robotsexist and rigorous proofs for recursive ... -
Economic Stochastic Model Predictive Control Using the Unscented Kalman Filter
(Journal article; Peer reviewed, 2018)Economic model predictive control is a popular method to maximize the efficiency of a dynamic system. Often, however, uncertainties are present, which can lead to lower performance and constraint violations. In this paper, ... -
Economic stochastic nonlinear model predictive control of a semi-batch polymerization reaction
(Journal article; Peer reviewed, 2019)Batch processes are ubiquitous in the chemical industry and difficult to control, such that nonlinear model predictive control is one of the few promising control techniques. Many chemical process models however are affected ... -
EEG Channel-Selection Method for Epileptic-Seizure Classification Based on Multi-Objective Optimization
(Peer reviewed; Journal article, 2020)We present a multi-objective optimization method for electroencephalographic (EEG) channel selection based on the non-dominated sorting genetic algorithm (NSGA) for epileptic-seizure classification. We tested the method ... -
EEG source imaging of hand movement-related areas: An evaluation of the reconstruction accuracy with optimized channels
(Journal article; Peer reviewed, 2023)The hand motor activity can be identified and converted into commands for controlling machines through a brain-computer-interface (BCI) system. Electroencephalography (EEG) based BCI systems employ electrodes to measure ... -
EEG-Based Alcohol Detection System with AI Techniques: Towards the Design of BCI Systems for Driver Monitoring
(Master thesis, 2023)Denne masteroppgaven undersøker muligheten for å detektere tilstedeværelsen av alkohol i elektroencefalografi (EEG)-signaler. I dag er alkoholpåvirket kjøring et verdensomspennende problem. Målet med dette prosjektet er å ... -

EEG-Based Emotion Experiment: Automatic Recognition with Machine Learning
(Master thesis, 2023)Følelser er en viktig del av livet og har en stor innvirkning i vårt daglige liv. Det å forstå og kunne kontrollere følelser kan for noen føre til bedre selvbevissthet, empati og livskvalitet. Tradisjonelle metoder for ... -
EEG-based Subjects Identification based on Biometrics of Imagined Speech using EMD
(Chapter, 2018)When brain activity ions, the potential for human capacities augmentation is promising. In this paper, EMD is used to decompose EEG signals during Imagined Speech in order to use it as a biometric marker for creating a ... -
Effect of cage size on oxygen levels in Atlantic salmon sea cages: A model study
(Peer reviewed; Journal article, 2022)The supply of dissolved oxygen (DO) to salmon in sea cages depends on many interacting factors including biomass density, temperature and current speed. With other factors being equal, hypoxic conditions are more likely ... -
Effect of non-ideal power take-off on the electric output power of a wave energy converter under suboptimal control
(Chapter, 2021)This work investigates how the physical limitations and losses of an electric power takeoff (PTO) system affect the production of power for a wave energy converter (WEC) under suboptimal control strategies. The damping of ... -
Effect of sensor location on continuous intraperitoneal glucose sensing in an animal model
(Journal article; Peer reviewed, 2018)In diabetes research, the development of the artificial pancreas has been a major topic since continuous glucose monitoring became available in the early 2000’s. A prerequisite for an artificial pancreas is fast and reliable ...
