Ceramics are highly technical materials with properties of interest for multiple industries. Precisely because of their high chemical, thermal, and mechanical resistance, ceramics are difficult to mold into complex shapes. A possibility to make convoluted ...
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 ...
ELSEVIER2022Homogenization-based design of microstructured membranes: wake flows past permeable shells
François Gallaire, Edouard Boujo, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna
A formal framework to characterize and control/optimize the flow past permeable membranes by means of a homogenization approach is proposed and applied to the wake flow past a permeable cylindrical shell. From a macroscopic viewpoint, a Navier-like effecti ...
CAMBRIDGE UNIV PRESS2021A 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 ...
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 ...
2020Engineered 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, ...
SPIE-INT SOC OPTICAL ENGINEERING2019Restoration 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 ...
ICOMOS2019Optimizing Micro-Tiles in Micro-Structures as a Design Paradigm
Annalisa Buffa, Pablo Antolin Sanchez
In recent years, new methods have been developed to synthesize complex porous and micro-structured geometry in a variety of ways. In this work, we take these approaches one step further and present these methods as an efficacious design paradigm. Specifica ...

2019Optimum Truss Design with Reused Stock Elements
Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting, Joseph Jean François Desruelle
This paper proposes the application of optimization techniques to design reticular structures made from a stock of reused elements. Still little explored, the reuse of structural components over multiple service lives has the potential to reduce the enviro ...
