Geology of the Northern Apennines nappe stack on eastern Elba (Italy): new insights on the Neogene orogenic evolution of the Northern Tyrrhenian Sea
(Peer reviewed; Journal article, 2021)We document the tectonic and metamorphic evolution of thrust nappes of the eastern island of Elba. The area exposes a natural cross section of the Northern Apennines hinterland, from the metamorphic basement units to the ... -
GeomDiff - An Algorithm for Differential Geospatial Vector Data Comparison
(Peer reviewed; Journal article, 2020)Diffs, a concept known from source code version control systems such as git, is interesting for geospatial, event-based workflows. We investigate how the native mathematical structure of vector geometries can be utilized ... -
Geomechanical analysis of the influence of CO2 injection location on fault stability
(Peer reviewed; Journal article, 2016)Large amounts of carbon dioxide (CO2) should be injected in deep saline formations to mitigate climate change, implying geomechanical challenges that require further understanding. Pressure build-up induced by CO2 injection ... -
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 ... -
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 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 ... -
