Based on the detailed geochemical studies of 184 soil samples from Periyar River Basin (PRB), a tropical monsoon dominated river basin (5398 km2) in the southern western Ghats (WGs) of India, a baseline reference data is established. The soils are mildly acidic with sandy loam and silt loam facies in non‐monsoon to sandy loam and sandy clay loam in monsoon. The mean metal concentrations follow the...
With the expansion of digital world, the scope of copyright has started facing a great threat. Thus, there is a need to protect the original work from being copied or distributed illegally. Image watermarking plays a very important role in solving this issue. Image watermarking is the procedure to embed a particular piece of information (watermark) in an image such that it is not distorted. Thus on...
The Direction of Arrival (DOA) technology and researches are evolving areas in array signal processing. Biomedicine, sonar, radar, seismology, astronomy communication and earthquake widely use this estimation. We receive an incoming wave by sensing an array or a set of arrays, this sensed wave can be processed to derive many related estimation information of the associated wave. The Direction of arrival...
Cloud computing is a field which has been rapidly developing over the past few years. The fact that cloud can offer both storage and computation at low rates makes it popular among corporations and IT industries. This also makes it a very attractive proposition for the future. But in spite of its promise and potential, security in the cloud proves to be a cause for concern to the business sector....
Multilevel inverters have been attracting attention in recent years due to high power quality, high-voltage capability, low switching losses, and low EMC concerns. Hence a detailed work has been done on the design and performance study of a three-phase five-level imbricated cells PWM inverter. The heavy and bulky transformers that have been used in traditional inverters are eliminated completely from...
