ABSTRACT
In the last two decades, underwater acoustic communications has
experienced significant progress. The traditional approach for ocean-
bottom or ocean-column monitoring is to deploy oceanographic sensors,
record the data, and recover the instruments. But this approach failed
in real-time monitoring. The ideal solution for real-time monitoring of
selected ocean areas for long periods of time is to connect various
instruments through wireless links within a network structure. Basic
underwater acou ....etc

Acoustic cryptanalysis is a side channel attack which exploits sounds, audible or not, produced during a computation or input-output operation. In 2004, Dmitri Asonov and Rakesh Agrawal of the IBM Almaden Research Center announced that computer keyboards and keypads used on telephones and automated teller machines (ATMs) are vulnerable to attacks based on differentiating the sound produced by different keys. Their attack employed a neural network to recognize the key being pressed. By analyzing recorded sounds, they were able to recover the tex ....etc

Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress the propagation of damage. In these studies, the SMA is used as an actuator. A multi-functional SMA as both sensor and actuator is suitable for constructing intelligent material, such as a material with a sensing and suppressing function. The damage of materials is related to the amount of strain. We studied the use of SMA wire parts as sensors to measure the amount of strain for damage estimation. The acoustic emission (AE) signals induced by phase tran ....etc

Acoustic Cryptanalysis Attempts on CPU and Keyboard

ABSTRACT
Acoustic sound is a natural phenomenon which can be emitted from interactions among physical objects or materials with its specific acoustic signature in frequency, amplitude and signal pattern or spectra. The emission occurs when a small surface displacement of a material is produced due to a rapid release of energy in a material, or on its surface. Acoustic sound which has specific spectra signature could be a powerful tool to reveal important information from the object bein ....etc

Thermo acoustic Refrigeration is based on the principles of creation of temperature gradient from sound waves and this theory was first developed in 1960s. Unlike vapour compression system, Thermo acoustic engines uses inert gases which is safe and no adverse effect on the atmosphere like the depletion of ozone layer and global warming.

Even though acoustic Refrigeration is efficient and cost effective its commercial application is warranted the need of more R&D efforts for technology up gradation and standardization without which its eff ....etc
