Understanding the role of Hubbard corrections in the rhombohedral phase of BaTiO3
Nicola Marzari, Iurii Timrov, Michele Kotiuga, Lorenzo Bastonero
We present a first-principles study of the low-temperature rhombohedral phase of BaTiO3 using Hubbardcorrected density-functional theory. By employing density-functional perturbation theory, we compute the onsite Hubbard U for Ti(3d) states and the intersi ...
College Pk2023Conjugate heat transfer in isolated granular clusters with interstitial fluid using lattice Boltzmann method
The conjugate heat transfer in mixtures of a fluid and single granular clusters is studied in this paper using a novel lattice Boltzmann method (LBM) programmed for parallel computation on the graphics processing unit (GPU). The LBM is validated for heat c ...
PERGAMON-ELSEVIER SCIENCE LTD2022An unrefinement algorithm for planar THB-spline parameterizations
Unrefinement is a tool that allows to perform faster numerical simulations by controlling the level of precision in the specified area. We introduce an algorithm that creates a coarser geometry from an initial regular geometry, which is represented with re ...
ELSEVIER2022Reduced order modelling of nonaffine problems on parameterized NURBS multipatch geometries
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution explores the combined capabilities of reduced basis methods and IsoGeometric Analysis (IGA) in the context of parameterized partial differential equations. The introduction of IGA enables a unified simulation framework based on a single g ...
2022GeoNeRF: Generalizing NeRF with Geometry Priors
We present GeoNeRF, a generalizable photorealistic novel view synthesis method based on neural radiance fields. Our approach consists of two main stages: a geometry reasoner and a renderer. To render a novel view, the geometry reasoner first constructs cas ...
IEEE COMPUTER SOC2022A Trojan Horse across the Channel: On the circulation of Vincenzio Viviani’s divinatio through his correspondence with Robert Southwell
Simon François Dumas Primbault
Self-proclaimed Galileo’s last disciple, Vincenzio Viviani (1622-1703) strove all his life to become a renowned mathematician. Extolling the supposed purity of Euclid’s geometry, he sought to recover the lost knowledge of the Ancients, and fashioned himsel ...
2021Resin Transfer molding of High-Fluidity Polyamide-6 with modified Glass-Fabric preforms
Véronique Michaud, Damiano Salvatori, Baris Çaglar, Robin Samuel Trigueira, Colin Gomez
In Resin Transfer Molding (RTM), resin precursors of thermoset or, more recently, thermoplastic polymers are generally employed, raising issues related to the chemical reaction taking place during and after part processing. In this study, already polymeriz ...
2021Design and fabrication of piezoelectric coupled MEMS resonators
Multilayer MEMS resonators with physical constraints (coupling beams) were designed, fabricated and characterized, including cantilevers and clamped-clamped beams. This project focused on how the resonance frequencies and coupling constant depend on the ge ...
2020Modeling of TAE mode excitation with an antenna in realistic X-point geometry
Experimentally, it is observed that Toroidal Alfven Eigenmodes (TAEs) are difficult to excite with an external antenna when the plasma is in X-point geometry. Here, the effect of the X-point geometry on the efficiency of the TAE excitation with the externa ...
AMER INST PHYSICS2020Engineered nanostructures' characterization by spectral interferometric microscopy
Toralf Scharf, Michail Symeonidis
We characterize engineered nanostructures with sizes smaller than half a wavelength using spectrally resolved interferometry. We analyze the response of the meta-atom of interest, which has a raspberry-like geometry. To identify the origin of the response, ...
