Note on the invariant classification of vacuum type D spacetimes
(Journal article; Peer reviewed, 2009-12)We illustrate the fact that the class of vacuum type D spacetimes which are I-non-degenerate are invariantly classified by their scalar polynomial curvature invariants. -
Notetaking in Minecraft and the Educational Use of Video Games: An Experimental Study
(Bachelor thesis, 2023)Dataspill-basert læring er ingen ny idé. Likevel er forskning rundt det uklar. Denne studien forsøker å forstå feltet bedre, og bidra til det. Det ble gjort ved å sammenligne resultater på en kunnskapstest, utført av ... -
”Nothing About Us Without Us”: the first example of inclusive research in Early Childhood Education in Norway
(Peer reviewed; Journal article, 2023)The term inclusive research is used in literature to describe a partnership between academics and people with intellectual disabilities, with the aim of conducting research together. This type of partnership must contain ... -
Nothing is in the air
(Peer reviewed; Journal article, 2017-03)It has often been argued that “there is something in the air” which makes firms in high-density environments—such as cities or clusters—more innovative. The co-location of firms facilitates the emergence of serendipity and ... -
A novel approach based on artificial neural network for calibration of multi-hole pressure probes
(Peer reviewed; Journal article, 2020)Imperfections in the manufacturing process of flow measuring probes affect their measuring behavior. Nevertheless, in order to provide the highest possible accuracy, each individual multi-hole pressure probe has to be ... -
Novel Data Encodings For Quantum Machine Learning: Enhancing the Quantum Feed-forward Neural Network for Improved Image Recognition
(Master thesis, 2023)Quantum machine learning combines the realms of quantum computing with artificial intelligence, providing novel approaches to problem-solving. Quantum image recognition is one such problem that has attracted significant ... -
Novel deconvolution method for extreme FPSO vessel hawser tensions during offloading operations
(Peer reviewed; Journal article, 2022)Robust prediction of extreme hawser tensions during Floating Production Storage and Offloading (FPSO) operations is an important safety and reliability concern. Excessive hawser tension may occur during certain environmental ... -
A novel design approach for estimation of extreme load responses of a 10-MW floating semi-submersible type floating wind turbine
(Peer reviewed; Journal article, 2022)Offshore structures are constructed to withstand extreme wind and wave-induced loads, so studying these extreme loads is vital as it allows offshore structures, e.g., wind turbines, to be designed and operated with minimal ... -
A novel design of a hybrid glulam-steel substructure for the IEA 15-MW floating wind turbine
(Peer reviewed; Journal article, 2023)Wind energy has become increasingly recognised as a very promising type of renewable energy. In addition, floating offshore wind turbines have facilitated the development of electricity production in intermediate (45-150 ... -
A Novel Empirical and Deep Ensemble Super Learning Approach in Predicting Reservoir Wettability via Well Logs
(Peer reviewed; Journal article, 2022)Accurately measuring wettability is of the utmost importance because it influences several reservoir parameters while also impacting reservoir potential, recovery, development, and management plan. As such, this study ... -
A novel method for prediction of extreme wind speeds across parts of Southern Norway
(Peer reviewed; Journal article, 2022)The paper describes a novel structural reliability method, particularly suitable for multi-dimensional environmental systems, either measured or numerically simulated over a sufficient period, resulting in sufficiently ... -
Novel methods for coupled prediction of extreme wind speeds and wave heights
(Peer reviewed; Journal article, 2023)Two novel methods are being outlined that, when combined, can be used for spatiotemporal analysis of wind speeds and wave heights, thus contributing to global climate studies. First, the authors provide a unique reliability ... -
Novel methods for reliability study of multi-dimensional non-linear dynamic systems
(Peer reviewed; Journal article, 2023)This research presents two unique techniques for engineering system reliability analysis of multi-dimensional non-linear dynamic structures. First, the structural reliability technique works best for multi-dimensional ... -
A Novel Model for Risk Regulations in the Offshore Oil and Gas Industry
(Peer reviewed; Journal article, 2022)Increasing interest from stakeholders has brought about a new emphasis on risk regulation in the oil and gas industry. Our basis for this work is the offshore oil and gas industry, which is composed of major operators, ... -
A novel MRI index for paraspinal muscle fatty infiltration: reliability and relation to pain and disability in lumbar spinal stenosis: results from a multicentre study
(Journal article; Peer reviewed, 2022-07-20)Background Fatty infiltration of the paraspinal muscles may play a role in pain and disability in lumbar spinal stenosis. We assessed the reliability and association with clinical symptoms of a method for assessing fatty ... -
A novel multi regional reliability method for Covid-19 death forecast
