The INFN NEMO-OνDE (Ocean Noise Detection Experiment) station, deployed on the seafloor at 2000 m depth 25 km offshore Catania (Sicily, Italy) in year 2005, was designed to continuously transmit broad-band acoustic data through optical cables to the INFN lab located in the port of Catania. It was operational until November 2006, when it was replaced by other experimental equipment. During the o...

Oily fine particles are an important air pollutant in industrial environments. Workers exposed to oil mist for a long time face great health risks. Particle growth pretreatment is technical principle increase particle size and improve purification efficiency. Acoustic waves commonly used acheive growth, large number of acoustic wave agglomeration experiments have been carried out on non-oil fog...

Over the past five years we have investigated and used commercial fishing vessels and their associated acoustic hardware as platforms for acoustic surveying and data collection. During this period we developed an automated acoustic logging system that will simultaneously record data from the ship’s existing sounder, sonar, and navigation systems. The system was designed to be self contained and...

Because computers may contain or interact with sensitive information, they are often airgapped and in this way kept isolated and disconnected from the Internet. In recent years the ability of malware to communicate over an air-gap by transmitting sonic and ultrasonic signals from a computer speaker to a nearby receiver has been shown. In order to eliminate such acoustic channels, current best p...

one of the nondestructive methods for assessing the internal quality of some fruits is the processing and analyzing the sound signals generated by an impact on the fruit. in this regard determining the location and the suitable impact levels for a certain fruit is required. in this study, the selected crimson sweet variety of watermelon was used for the acoustic tests by imposing the impact for...

the present study provides an analysis of the correlation between acoustic properties, duration and pitch amplitude of speech associated with three basic emotions: anger, sadness and joy against neutrality as a reference, emotionally expressed by six persian speakers. rise/fall connection model (taylor, 1995) is used to analyze acoustic parameters and measure how an utterance is modulated when ...

Acoustic Emission applied to mechanically loaded Paper (AEP) is a current European Union funded Fifth Framework project. The overall objective of this project is to investigate the micro mechanics behind the behaviour of paper under mechanical loading, with a view to enabling the development of new and value added paper products with a better competitive edge in the global market. To achieve th...
