Geomechanical modelling of subsidence and induced seismicity in a gas reservoir
(Master thesis, 2015)Reservoir compaction and associated surface subsidence, fault reactivation and induced earthquakes are observed in many petroleum fields worldwide. A better understanding of the geomechanical behaviour of reservoir rocks ... -
Geomechanics and Rock Physics of Anisotropic Overburden Shales
(Doctoral theses at NTNU;2023:326, Doctoral thesis, 2023)Shales, with their diverse composition and complex properties, present an interesting research subject and a challenging material to work with. As they constitute a significant portion of the overburden in most currently ... -
A Geometallurgical Approach Applied to the Tromsdalen Calcite Operation
(Doctoral theses at NTNU;2020:161, Doctoral thesis, 2020)The motivation behind the thesis was to increase the knowledge and to expand the possibilities within industrial mineral mining, an important mining sector in Norway. This was done through extensive deposit study and an ... -
Geometallurgical Approach to the Element-to-Mineral Conversion for the Nabbaren Nepheline Syenite Deposit
(Journal article; Peer reviewed, 2018)Nabbaren nepheline syenite, a silica-deficient intrusive rock with low Fe content, was the industrial mineral deposit study case in this study. The quality of industrial mineral products are generally based on their bulk ... -
Geometallurgical Flowsheet as a Tool for Designing and Communicating Geometallurgical Programs
(Journal article; Peer reviewed, 2018)This paper introduces the concept of using a geometallurgical flowsheet as a tool to design, visualize and communicate a geometallurgical program. The development of the concept is carried out using a case study of an ... -
Geometallurgical Modelling of the Stjernøya Nepheline Syenite Mine
(Doctoral theses at NTNU;2019:385, Doctoral thesis, 2019)The present study applies the concept of geometallurgy to an industrial mineral case study. Geometallurgy is a holistic discipline conveying different aspects of geology, mineral processing and mining together to improve ... -
Geometric Accuracy in Laser- Based Powder Bed Fusion of Polymers: Tolerance optimization by part build orientation
(Doctoral theses at NTNU;2022:71, Doctoral thesis, 2022)As Additive Manufacturing (AM) enters the manufacturing industry, the technology must adhere to stringent quality demands in terms of dimensional and geometric accuracy. However, due to substantial differences in how these ... -
Geometric and Functional Analytic Aspects of Time-Frequency Analysis
(Doctoral theses at NTNU;2022:74, Doctoral thesis, 2022)Sammendrag på norsk Denne avhandlingen omhandler geometriske og funksjonalanalytiske aspekter ved tid-frekvensanalyse. Mer spesifikt drøfter avhandlingen de tre følgende delvis relaterte temaene: Dekomponeringsrom: I ... -
Geometric and integrability properties of Kahan?s method: The preservation of certain quadratic integrals
(Peer reviewed; Journal article, 2019)Given a quadratic vector field on possessing a quadratic first integral depending on two of the independent variables, we give a constructive proof that Kahan's discretization method exactly preserves a nearby modified ... -
Geometric and Qualimetric Modelling of the Hessjø deposit
(Master thesis, 2016)The main goal of this master thesis is to develop geometric and qualimetric 3D-models the Hessjø deposit, located in Holtålen, Norway, using data acquired in the 1970s. This includes a thorough evaluation of the data in ... -
Geometric Aspects of Quantum Entanglement
(Doctoral thesis at NTNU;2016:253, Doctoral thesis, 2016)Summary: Entanglement is a strange feature contained in the quantum mechanical framework, first observed theoretically by Erwin Schrödinger and Albert Einstein. An inherent attribute of entanglement is non-locality, and ... -
Geometric Change Detection in Digital Twins using 3D Machine Learning
(Peer reviewed; Journal article, 2021)Digital twins are meant to bridge the gap between real-world physical systems and virtual representations. Both stand-alone and descriptive digital twins incorporate 3D geometric models, which are the physical representations ... -
