Acoustic cryptanalysis


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 ....etc

Acoustic Emission Based Machining Tool Condition Monitoring – An Overview



ABSTRACT
Acoustic emission technique (AET) has been extensively researched and found to be one of the most of the most promising techniques for condition monitoring of machine tools. AE is non-intrusive, simple in operation and fast dynamic response. This paper discusses the applicability of AET for monitoring machine tool wear and breakage. This is followed by discussions on the re ....etc

ABSTRACT.

Acoustic emission technique (AET) has been extensively researched and found to be one of the most of the promising techniques for condition monitoring of machine tools. AE is non-intrusive, simple in operation and gives fast dynamic response.
Acoustic Emission Technique (AET) is relatively recent entry in the field of NDE which has particularly shown a very high potential for material characterization and damage assessment in co ....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

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
