Characterizing the seabed in the Straits of Florida by using acoustic noise interferometry and time warping

The Journal of the Acoustical Society of America, 2019
Interferometry of ambient and shipping noise in the ocean provides a way to estimate physical parameters of the seafloor and the water column in an environmentally friendly manner without employing any controlled sound sources. With noise interferometry, two-point cross-correlation functions of noise serve as the probing signals and replace the Green's

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Experimental investigation of the sound behavior of a three-phase asynchronous machine under variable frequency operation

Ain Shams Engineering Journal
In industry, where acoustic characterization is becoming the preferred non-invasive technique, the diagnosis of problems in three-phase asynchronous machines is essential. Without the requirement for sensors installed directly on the machine, it makes it

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Audiogram of ceramic friction noises in total hip arthroplasty and their relationship with acetabular component position

Гений oртопедии
Introduction Noise from a total hip replacement's ceramic friction pair is known as hip squeaking. Acoustic arthrometry in total hip replacement (THR) involves using acoustic emission technology to visualize sound characteristics. The objective was to

Auditory–Tactile Congruence for Synthesis of Adaptive Pain Expressions in RoboPatients

Advanced Robotics Research, EarlyView.
In this work, we explore auditory–tactile congruence for synthesizing adaptive vocal pain expressions in robopatients. Using a robopatient platform that integrates vocal pain sounds with palpation forces, we conducted 7680 trials across 20 participants.
