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 ... -
Geometric Hodge filtered complex cobordism
(Peer reviewed; Journal article, 2023)We construct a geometric cycle model for a Hodge filtered extension of complex cobordism for every smooth manifold with a filtration on its de Rham complex with complex coefficients. Using a refinement of the Pontryagin–Thom ... -
Geometric Integration of ODEs Using Multiple Quadratic Auxiliary Variables
(Journal article; Peer reviewed, 2022) -
Geometric morphometric analysis of Pleuronectiformes vertebrae: A new tool to identify archaeological fish remains?
(Journal article; Peer reviewed, 2023)Flatfish (Pleuronectiformes) vertebrae are difficult to identify to species due to the lack of diagnostic features. This has resulted in a lack of understanding of the species abundances across archaeological sites, hindering ... -
Geometric pushforward in Hodge filtered complex cobordism and secondary invariants
(Journal article; Peer reviewed, 2024)We construct a functorial pushforward homomorphism in geometric Hodge filtered complex cobordism along proper holomorphic maps between arbitrary complex manifolds. This significantly improves previous results on such ... -
Geometric Reduced-Attitude Control of Fixed-Wing UAVs
(Peer reviewed; Journal article, 2021)This paper presents nonlinear, singularity-free autopilot designs for multivariable reduced-attitude control of fixed-wing aircraft. To control roll and pitch angles, we employ vector coordinates constrained to the unit ... -
Geometrical flexibility of platinum nanoclusters: impacts on catalytic decomposition of ethylene glycol
(Journal article; Peer reviewed, 2017)Catalytic decomposition of ethylene glycol on the Pt13 cluster was studied as a model system for hydrogen production from a lignocellulosic material. Ethylene glycol was chosen as a starting material because of two reasons, ... -
Geometrical Study of Virus RNA Sequences
(Journal article, 2021)In this contribution, some applications of the earlier developed fast algorithm of calculating coordinates of single nucleotides and RNA fragments are considered to create multi-scale geometrical models of RNAs and their ... -
Geometrically derived efficiency of slow immiscible displacement in porous media
(Peer reviewed; Journal article, 2020)The efficiency of a displacement is the fraction of applied work over the change in free energy. This displacement efficiency is essential for linking wettability to applied work during displacement processes. We quantify ... -
Geometry deviation effects of railway catenaries on pantograph–catenary interaction: a case study in Norwegian Railway System
(Peer reviewed; Journal article, 2021)This paper presents a non-contact measurement of the realistic catenary geometry deviation in the Norwegian railway network through a laser rangefinder. The random geometry deviation is included in the catenary model to ... -
Geometry effect on fracture behavior of V-notched specimens
(Peer reviewed; Journal article, 2020)Geometric constraint is one of the important issues that affect the fracture behavior of different notched components. Specimens with the same notch geometry can have different fracture strengths due to the geometric ... -
Geometry-Based Modeling of Wideband Industrial Indoor Radio Propagation Channels
(Chapter, 2015)In this paper, we present a geometrical scattering model for a typical class of industrial indoor environments. The proposed industrial reference model takes into account scattering components arising from metallic structures ... -
Geophysical and Geochemical Proxies of Neolithic Sites from Thessaly: A Comparative Study on the Potential of Soil Magnetic Susceptibility and Phosphate Analyses for Minimally Invasive Location and Interpretation of Buried Features
(Peer reviewed; Journal article, 2022)This paper presents the results of a study exploring the potential of magnetic-susceptibility and phosphate soil analyses to locate and characterize buried Neolithic settlements in Thessaly, Greece. Using the preliminary ... -
Geophysical characterisation of two segments of the Møre-Trøndelag Fault Complex, Mid-Norway
(Journal article; Peer reviewed, 2011)The Møre-Trøndelag Fault Complex (MTFC) has controlled the tectonic evolution of Mid Norway and its shelf for the past 400 Myr through repeated reactivations during Palaeozoic, Mesozoic and perhaps Cenozoic times, the very ... -
Geophysical electromagnetic modeling and evaluation: A review
(Peer reviewed; Journal article, 2021)Electromagnetic forward modeling is the cornerstone of geophysical electromagnetic inversion. During the last 50 years, numerical simulation methods have been rapidly developed and widely used in geophysical area as the ... -
Geophysical expression of the Leka Ophiolite, Norway modeled from integrated gravity, magnetic and petrophysical data
(Journal article; Peer reviewed, 2018)The ca. 497 Ma Leka Ophiolite Complex (LOC) comprises oceanic lithosphere that formed near the margin of Laurentia in a suprasubductionzone setting. The LOC was obducted onto Laurentia in the Early Ordovician and later ... -
Geophysical Field Data Interpolation Using Stochastic Partial Differential Equations for Gold Exploration in Dayaoshan, Guangxi, China
(Journal article; Peer reviewed, 2019)In a geophysical survey, one of the main challenges is to estimate the physical parameter using limited geophysical field data with noise. Geophysical datasets are measured with sparse sampling in a survey. However, the ... -
Geophysical prospection of Iron Age coastal sites in Scandinavia known from metal detecting assemblages – new case studies from the PastCoast-project
(Chapter, 2023)Geophysical surveying of sites known from metal detecting shows a varying spatial relationship between the finds material and the geophysical information. The survey results of two case studies indicate that coastal erosion ... -
Geophysical Surveys
(Chapter, 2017)This chapter presents the geophysical surveys of Avaldsnes carried out by several actors between 2004 and 2013 and discusses the surveys’ results. An important part of the discussion is a quantitative and qualitative ... -
Geopolitical threats, equity returns, and optimal hedging
(Journal article; Peer reviewed, 2023)In this paper, we demonstrate that the U.S. equity market and a few specific sectors produce significantly positive returns during high geopolitical threats, even with the presence of standard controls, whereas other major ...
