Investigation of Loss Calculation Methods for PMSMs and Implementation of Loss Functionality on a Developed FEM Model
(Master thesis, 2016)Accurate estimation of losses is one of the major challenges in electromagnetic machinery modelling. Where permanent magnet synchronous machines are attractive for high performance applications, making them relevant for ... -
Investigation of loss of surfactants during enhanced oil recovery applications - adsorption of surfactants onto clay materials
(Master thesis, 2013)Chemical flooding, or surfactant flooding, is a well known EOR technique which has been used worldwide for decades. For this method to be economically feasible, it is crucial to minimize the loss of surfactant to the ... -
Investigation of Low Temperature Toughness and Crack Initiation In Welded Structural Steels
(Master thesis, 2014)A 420 MPa HSLA steel has been investigated. Instrumented Charpy impact tests and quasi-static CTOD tests have been performed on specimens of weld simulated Coarse Grained Heat Affected Zone (CGHAZ) and Intercritically ... -
Investigation of low-pressure environment to alter layer temperature of high-performance polymer parts printed with Fused Filament Fabrication
(Master thesis, 2023)Additiv fremstilling (AM) av høytytende polymer (HPP) ved bruk av Fused Filament Fabrication (FFF) har kommet langt, men sliter fortsatt med å produsere store komponenter med best mulige materialegenskaper. Den mest ... -
Investigation of LTE Privacy Attacks by Exploiting the Paging Mechanism
(Master thesis, 2018)In mobile communication in general, and LTE in particular, security should be a main focus, also because of the vulnerabilities introduced by the radio link. Compared to GSM and UMTS, the LTE security has been improved. ... -
Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
(Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
Investigation of magnetic field and radial force harmonics in a hydrogenerator connected to a three-level NPC converter
(Chapter, 2017)This paper investigates spatial and time harmonics of flux density and radial force distributions in the airgap of a hydrogenerator with fractional-slot windings. Hydrogenerator is connected to a neutral-point-clamped (NPC) ... -
Investigation of manufacturability of grid structures of the structural part of Flying V using additive manufacturing
(Master thesis, 2022)Bevisstheten om klimaendringer øker blant alle sektorer – inkludert luftfart. For å redusere den globale påvirkningen av luftfart, bør drivstoffbruken reduseres drastisk. TU Delft designet en ny konfigurasjon for et fly ... -
Investigation of mechanical properties for medium-dense hardwoods, focusing on beech, birch and oak.
(Master thesis, 2020)En undersøkelse av de mekaniske egenskapene til et utvalg hardtre av medium tetthet er blitt gjennomført. Innledningsvis er bakgrunnsteori om tre og trestrukturen presentert. Treslagene som ble undersøkt i studien var bøk ... -
Investigation of mental stress detection with an 8-channel EEG system using KNN, SVM and EEGNet
(Master thesis, 2023)Det er viktig å påpeke at dette arbeidet er gjort som en fortsettelse av prosjektoppgaven av Marthinsen [1]. Derfor vil det være seksjoner, spesielt i chapter 2, som vil være sterkt inspirert av eller direkte gjenbrukt fra ... -

Investigation of metal dusting corrosion process over UNS N08800 alloy
(Journal article; Peer reviewed, 2017)Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ... -
Investigation of metallic bipolar plates for PEM fuel cells
(Master thesis, 2011)High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ... -
Investigation of Methods for 2D Strain Imaging of Brain Tumors
(Master thesis, 2014)Intraoperative ultrasound strain imaging displays brain tissue stiffness rather than difference in mass density as regular B-mode imaging. A glioma (the most common type of brain tumor) has a tendency of infiltrating ... -
Investigation of methods for speckle contrast reduction
(Master thesis, 2010)Speckle arises when coherent light is reflected from a rough screen and observed by an intensity detector with a finite aperture. Because speckle causes serious image degradation when lasers are used as light sources in ... -
