Investigation of Contact Erosion and Arc-Welding in a Medium Voltage Switching Device Using COMSOL
(Master thesis, 2019)Denne master oppgaven omhandler effektene lysbuen hadde på en mellomspennings effektbryter under lukkeoperasjoner. Hovedmålet for oppgaven var å finne den totale kontakterosjonen og styrken på lysbuesveisen etter at lukking ... -
An investigation of contemporary data-driven methods applied to complex systems
(Peer reviewed; Journal article, 2022)Understanding complex systems by the help of modeling, simulation, and control is a well-known challenge across several application domains. As such, these type of systems are not amenable to empirical models, typically ... -
An Investigation of Credit Card Default Prediction in the Imbalanced Datasets
(Peer reviewed; Journal article, 2020)Financial threats are displaying a trend about the credit risk of commercial banks as the incredible improvement in the financial industry has arisen. In this way, one of the biggest threats faces by commercial banks is ... -
Investigation of Dielectric Response Measurement as a Tool to Detect Copper Sulphide on Insulation Paper
(Master thesis, 2008)Several power transformers has, during the last two decades, broken down due to the copper sulphideproblem. Corrosive sulphur reacts with the copper conductor contaminating the surroundinginsulating paper. To this day there ... -
Investigation of distortions in microgrids
(Master thesis, 2016)This thesis presents a validation study based on data analysis aimed at identifying the cause of atypical behavior observed in a microgrid's data. The data of a stand-alone PV microgrid in Bhutan is analyzed. The analysis ... -
Investigation of Electrical Properties of a new low-GWP Insulation Gas - Comparison of AirPlus and Synthetic Air
(Master thesis, 2018)Sulfur hexafluoride (SF6) is a widely used insulation gas in medium- to high-voltage equipment due to its excellent dielectric properties. It has however one important weakness; a large global warming potential (GWP) of ... -
Investigation of Elementary Cellular Automata for Reservoir Computing
(Master thesis, 2016)Reservoir computing is an approach to machine learning. Typical reservoir computing approaches use large, untrained artificial neural networks to transform an input signal. To produce the desired output, a readout layer ... -
Investigation of errors in open-loop sigma-delta modulators utilizing analog modulo integrators
(Master thesis, 2006)This thesis is divided into two parts, the design of a practical first order open loop sigma-delta modu- lator using discrete components, and simulation of a third order OLSD ADC to investigate the consequences of circuit ... -
Investigation of High Accuracy Mixed-Signal Time-to-Digital Converter
(Master thesis, 2020)I denne masteroppgaven er hovedmålet å måle tiden mellom stigende flanker av to separate signaler. Det ble foreslått å bruke en såkalt ”Vernier Delay Line” (VDL), men problemet med dem er at nøyaktigheten er inkonsekvent ... -
Investigation of Interior Permanent Magnet Machines with Concentrated Windings for High Dynamics Applications
(Master thesis, 2015)Interior permanent magnet (IPM) machines and non-overlapping concentrated windings (CW) are two design philosophies that have grown in popularity over the last decade. This is due to the many benefits and flexibility they ... -
Investigation of Loss Calculation Methods for PMSMs and Implementation of Loss Functionality on a Developed FEM Model
