New Acoustic Design for the Piscina Mirabilis Located nearby the Port of Misenum

Heritage
Many heritage buildings from ancient Rome are being refurbished based on their original plan’s structure. One of them is the piscina mirabilis located nearby in Naples, which was a cistern used by the Romans to collect drinkable water for the navy ...

3D Interpolation in Wave-Based Acoustic Simulation [PDF]

IEEE Signal Processing Letters, 2022
In any acoustics simulation setting relying on computation over a spatial grid, interpolation of the acoustic field is essential in order to accurately model source and receiver positions. Most available approaches to 3D interpolation, such as those used in computer graphics or medical imaging, are based on polynomial or windowed-sinc designs.

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Possible Merits of the Orchestra Pit Covering for Speech Activities in Baroque Theatres

Applied Sciences
Acoustically, Baroque theatres have prove remarkably appropriate for opera, and, in the past, little distinction was drawn in design between drama and opera use, except for the inclusion of an orchestra pit, because both music and words were audible and ...

Acoustic Hypochlorite Activation in Simulated Curved Canals [PDF]

Journal of Endodontics, 2009
INTRODUCTION: It was the goal of this study to compare different NaOCl activation schemes regarding a desired and an untoward outcome. Ultrasonic tips and a currently marketed sonic system were used in conjunction with a 2.5% sodium hypochlorite solution.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Analysis of Measured and Simulated Supraglottal Acoustic Waves [PDF]

Journal of Voice, 2016
To date, although much attention has been paid to the estimation and modeling of the voice source (ie, the glottal airflow volume velocity), the measurement and characterization of the supraglottal pressure wave have been much less studied. Some previous results have unveiled that the supraglottal pressure wave has some spectral resonances similar to ...
