Electroacoustic analogies applied to acoustic oscillator analysis

Archives of Acoustics, 2014
Analogies were, so far, rarely applied to acoustic oscillator analysis, however, their use turns out to be advantageous. It allows, due to comparison of analogous electric and acoustic oscillators operation, for better understanding of the process of ...

Meteorological effects on long-range outdoor sound propagation [PDF]

Measurements of sound propagation over distances up to 1000 m were carried out with an impulse sound source offering reproducible, short time signals. Temperature and wind speed at several heights were monitored simultaneously; the meteorological data ...

Mechanically Compliant and Optically Tunable Metal Oxide‐PDMS Nanocomposite Thin Films as a Platform for Flexible Photonic Integration

Advanced Materials Interfaces, EarlyView.
This study demonstrates polydimethylsiloxane (PDMS) nanocomposite thin films incorporating ZnO and TiO2 nanoparticles, optimized using response surface methodology. The films exhibit tunable refractive index, high transparency, low optical loss, and sub‐MPa mechanical compliance.

Cu and Cu‐30Ni Alloy as Anti‐Viral Materials for High‐Touch Surfaces: Efficacy in a Simulated Public Environment with Frequent Cleaning Practices

Advanced Materials Interfaces, EarlyView.
This study evaluates the antiviral efficacy and corrosion behavior of pure copper and Cu‐30Ni alloy on high‐touch surfaces under simulated public conditions with periodic cleaning. Copper shows faster virus inactivation due to higher ion release, while Cu‐30Ni offers better aesthetic durability.

Property Prediction and Resilience Analysis in Polyionic Glasses Using a Machine‐Learning Algorithm with Multivariate Output

Advanced Materials Technologies, EarlyView.
A multivariate machine‐learning model is employed using Gaussian process regression to predict property profiles of complex glass formulations based on small but highly consistent datasets. Abstract Designing the chemical composition of multi‐component glasses toward a set of target properties requires information on a complex range of trade‐off ...
