Icing Detection for Small Fixed Wing UAVs using Inflight Aerodynamic Coefficient Estimation
(Peer reviewed; Journal article, 2019)In cold and humid environments, airfoil icing is a major hindrance to UAV operations. Airfoil icing increases the aerodynamic drag coefficient, while reducing the maximum lift coefficient and the stall angle. This results ... -
Icing detection for small fixed wing UAVs using inflight aerodynamic coefficient estimation
(Chapter, 2016)We propose a method to detect icing of the airfoil of a fixed-wing Unmanned Aerial Vehicle by using an aerodynamic coefficient estimator and ambient temperature and humidity sensors. The estimator uses the information ... -
Icing Detection on Leading Edge of Aircraft Wings
(Master thesis, 2016)In recent years, the use of UAVs has increased significantly, both for commercial and private use. UAVs are particularly favorable in situations where other alternatives are impractical, or poses a threat to human lives, ... -
Icing diagnosis in unmanned aerial vehicles using an LPV multiple model estimator
(Journal article; Peer reviewed, 2017)The phenomenon of icing, i.e. ice accretion on aircraft surfaces, affects the flight performance of unmanned aerial vehicles (UAVs). Autonomous icing detection schemes are needed in order to assure high efficiency and limit ... -
Identifiability and physical interpretability of hybrid, gray-box models - a case study
(Journal article; Peer reviewed, 2021)Model identifiability concerns the uniqueness of uncertain model parameters to be estimated from available process data and is often thought of as a prerequisite for the physical interpretability of a model. Nevertheless, ... -
Identifiable Prediction Animal Model for the Bi-Hormonal Intraperitoneal Artificial Pancreas
(Peer reviewed; Journal article, 2022)To achieve a fully automatic artificial pancreas (AP), i.e., an AP without the need for meal announcements, the intraperitoneal (IP) route is explored. This route has faster dynamics than the typical subcutaneous (SC) ... -
Identification and Classification of Electrical Loads in a Norwegian Household Using Energy Disaggregation Methods of Non-Intrusive Load Monitoring.
(Master thesis, 2019)Formålet med denne avhandlingen er å fastslå fordelene til forbrukerne ved innføring av smart strømmålere. Et eksperiment ble utformet for å samle inn totalt forbruksdata samt individuell apparatdata i et ikke-laboratoriemiljø ... -
Identification and Order Reduction of Radiation Force Models of Marine Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:188, Doctoral thesis, 2007) -
Identification of EEG-based signature produced by visual exposure to the primary colors RGB
(Master thesis, 2017)In this thesis we have presented results for experiments regarding identification of electroencephalograph (EEG) signatures produced by the visual exposure of primary colors i.e. red, green and blue (RGB) to the subject. ... -
Identification of Failure Modes in the Collision Avoidance System of an Autonomous Ferry using Adaptive Stress Testing
(Peer reviewed; Journal article, 2022)As complex autonomous systems emerge in the maritime sector, measures must be taken in order to ensure thorough safety assessment. Real world testing can be costly and potentially dangerous, and therefore there is a need ... -
Identification of spectral signature for in situ real-time monitoring of smoltification
(Peer reviewed; Journal article, 2021)We describe the use of an optical hyperspectral sensing technique to identify the smoltification status of Atlantic salmon (Salmo salar) based on spectral signatures, thus potentially providing smolt producers with an ... -
Identification, Inversion and Implementaion of the Preisach Hysteresis Model in Nanopositioning
(Master thesis, 2014)Atomic force microscopes offer the possibility for imaging a sample topography with accuracy in the nanometer scale. This kind of performance is impossible without actuators enabling a certain accuracy. A frequently used ... -
Identifikasjon av menneskelig aktivitet basert på kroppsmonterte sensorer
(Master thesis, 2008)Denne rapporten omhandler problematikken ved å detektere fysisk aktivitet hos personer med ulikt bevegelsesmønster. Aktivitet kan registreres av aktivitetsmålesystemer som samler data fra sensorer montert til kroppen. ... -
Identifying clothing articles by use of iterative classification
(Master thesis, 2018)Supervised machine learning is commonly applied in order to give machines the ability to assign labels to input data. Given a set of categories, the machine is tasked with identifying which class new observations belong ... -
