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 ... -

Investigation of Model Predictive Control Application in District Heating Systems with Distributed Sources
(Doctoral theses at NTNU;2022:273, Doctoral thesis, 2022)District heating (DH) systems, which can integrate various available heat sources, have proven to be an energy-efficient and environment-friendly way to satisfy buildings’ heating demands. However, with the transition from ... -
An Investigation of Models for Under-Reporting in the Analysis of Violence Against Women in Italy
(Journal article; Peer reviewed, 2023)Violence against women is still one of the most widespread and persistent violations of human rights. Despite this, a significant gap of comprehensive, reliable and up-to-date figures on such a largely uncovered phenomenon ... -
Investigation of Modified Silica Nanoparticles' Efficiency in Enhancing Oil Recovery - An Experimental Study
(Master thesis, 2015)As it has become difficult to discover new hydrocarbon resources, the focus has shifted towards innovative enhanced oil recovery (EOR) technologies that extract more oil out of producing reservoirs. The addition of modified ... -
Investigation of Moonpool Resonance as Vessel Damping Device
(Master thesis, 2016)The starting point of this thesis is to introduce the potential and the viscous flow formulations of a two-dimensional moonpool geometry, and the viscous approach demonstrates compliance with physical experiments. The ... -
Investigation of moonpools as pitch motion reducing device
(Peer reviewed; Journal article, 2021)Moonpools as a device for reducing pitch motion is investigated experimentally, numerically and by an approximate theory. A two-dimensional study is carried out of a rectangular body with two moonpools. Forced heave and ... -
Investigation of Multi-degradation Mechanisms in Different Stainless Steels in Direct Riser Tensioning Systems for Offshore Oil&Gas Industry
(Master thesis, 2015)Many components utilized in offshore industry are complex tribological systems, for instance Direct Riser Tensioner (DRT) cylinders which include the use of seals, guide bands, hydraulic fluids/lubricants and materials in ... -
Investigation of Multivariate Freight Rate Prediction Using Machine Learning and AIS Data
(Master thesis, 2018)This thesis investigates whether multivariate machine learning forecasting methods, using information extracted from Automatic Identification System (AIS) data, add additional information in predicting short-term freight ... -
Investigation of Nanoparticle Effect on Wettability and Interfacial tension: An Experimental Study of a Two-Phase System of Heavy Oil and Di Water
(Master thesis, 2013)The increasing demand for hydrocarbons has led to a hope of developing more efficient recovery techniques for unconventional resources such as heavy oil. Heavy oil is movable in the reservoir, but recovery is time-consuming ... -
