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 Pk2023Reduced 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 ...
2022An 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 ...
ELSEVIER2022Stabilized isogeometric discretizations on trimmed and union geometries, and weak imposition of the boundary conditions for the Darcy flow
Modern manufacturing engineering is based on a ``design-through-analysis'' workflow. According to this paradigm, a prototype is first designed with Computer-aided-design (CAD) software and then finalized by simulating its physical behavior, which usually i ...
EPFL2022Precise and accurate image-based measurements of optical material properties
The appearance of objects is governed by how they reflect, transmit and absorb the light they receive. That, in turn, depends on the material's internal structure, surface structure, and viewing and illumination directions. Changes in those characteristics ...
EPFL2020Modeling 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 PHYSICS2020Effects of multiple scattering on angle-independent structural color in disordered colloidal materials
Disordered packings of colloidal spheres show angle-independent structural color when the particles are on the scale of the wavelength of visible light. Previous work has shown that the positions of the peaks in the reflectance spectra can be predicted acc ...
AMER PHYSICAL SOC2020Design 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 ...
2020Restoration of ancient Chinese opera spiral wooden domes, accounts of field practice
Corentin Jean Dominique Fivet, Jingxian Ye
The zaojing is a wooden construction system that covers opera stages for rain protection and sound control. Zaojings in China display a diverse range of geometric expressions, delicate manufacturing, structural behaviours, and acoustic qualities. Despite t ...
ICOMOS2019Comparative analysis of transmittance measurement geometries and apparatus
Sabine Süsstrunk, Marjan Shahpaski
The accurate measurement of reflectance and transmittance properties of materials is essential in the printing and display industries in order to ensure precise color reproduction. In comparison with reflectance measurement, where the impact of different g ...
