A systematic experiment was conducted in the eastern Arabian Sea for the first time exclusivelyto study the characteristics of the Arabian Sea mini warm pool1. The analysis revealed complexnature of the thermohaline and sonic layer distributions across th... see more

3-D underwater parabolic equation model based on implicit finite difference method has been implemented for South Eastern Arabian Sea (SEAS). The bathymetric and geo-acoustic features have been integrated in the model for a 50 km circular region in SEAS. ... see more

Physical oceanographic and acoustic data were simultaneously collected from the coastalwaters of the Arabian Sea. Acoustic transmissions were carried out from an anchored vesselusing 620 Hz transducer and received by an array of hydrophones moored at ~5 k... see more

In this work, the spatial correlation of a multiple-input multiple-output (MIMO) for underwater acoustic (UWA) channel is modelled. To obtain the spatial correlation for such a channel, a mathematical method to model the effect of the surface on the acous... see more

Physical models of the formation of ballistic and muzzle waves generated during an artillery shot have been developed and investigated. A promising method for assessing the degree of wear of artillery barrels is the acoustic non-contact method. However, i... see more

Fine resolution spatial survey carried out off the west coast of India during June and December 2004 was utilised to study the transmission loss (TL) variability associated with the upwelling and downwelling processes in this region. During June, the upwe... see more

As a key component in power transfer, positive displacement machines often represent the major source of noise in hydraulic systems. Thus, investigation into the sources of noise and discovering strategies to reduce noise is a key part of improving the pe... see more

The acoustic quality in enclosed spaces is defined by the constructive characteristics of the environment, which must be designed to increase the propagation of the sound. Therefore, the sound message to be transmitted, whether spoken, song or by music in... see more

Acoustic wave modeling is very important for many applications such as the manufacturing of biometric sensors and detectors for flaws in metal structures. The simulation of acoustic waves is done using a finite difference time domain method (FDTD) method ... see more
