Development of Personal Computers and Cloud Computing, Internet of Things is making duplicating the data very feasible. In this paper we are proposing visible watermarking using FPGA which provides one to one compound mapping that allows reversible watermarking. This method can be applied for different types of host images like binary, opaque monochrome and translucent full color ones. The ultimate objective of the research is to develop low power, high performance, real-time, reliable and secured watermarking system which can provide robustness over certain attacks namely cover-up attack, cropping noise, scaling and geometric attacks. © 2015 IEEE.

Background: Collagen is a significant structural protein, the integrity of which is essential to be maintained for proper homeostasis. Oral submucous fibrosis, being a collagen metabolic disorder, may be subject to changes in amino acid profiling.Aim: The present study was attempted to evaluate the amino acid profile to assess its feasibility as a biological marker in OSMF.Materials and Methods: The study group comprised of 13 patents with OSMF and the normal group comprised of 13 normal patients without associated habits or systemic disorders. Venous blood was collected from the antecubital vein, plasma was separated and the plasma was then subjected to high profile liquid chromatographic analysis.Results: The assay levels of threonine, alanine and tyrosine did not yield any significant results. The decreased assay levels of valine, Isoleucine and the increased assay level of methionine and glycine observed in group II yielded significant results in correlation with the control group. The decreased assay level seen in phenylalanine in group II and III in correlation with group IV is statistically significant.Conclusion: A few amino acids have been identified which can be used as biological markers for the severity of the disease such as valine, methionine and phenyl alanine. Large scale studies are required to elucidate the potential of these biological markers. © 2014, Journal of Clinical and Diagnostic Research. All rights reserved.

Combined Economic Emission Dispatch (CEED) is a bi-objective problem, needs to find a generating pattern to minimize generating cost and emission. Generating cost and Emission are function of real power generation. Economic Load Dispatch (ELD) is used to find minimum generating cost but emission and other physical and control variables limits are not found. In CEED minimum generating cost along with minimum emission is calculated and subjected to real and reactive power balance equation, upper and lower bound of real and reactive power, voltage and MVA power transfer in the transmission lines. CEED in the earlier literatures is used to find minimum generating cost and emission but reactive power is not taken into account and line flow limits are not checked. In this paper CEED is solved to find its biobjective, real and reactive power losses are calculated using Newton Raphson (NR) method and subjected to power balance equality constraints and inequality constraints of real, reactive, voltage and line flow limits. Differential Evolution (DE) algorithm is used to solve this CEED, to validate results IEEE test case 30 bus is considered. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

As Advancing techniques are increasing in data communication, the problem of handling the intruder is becoming tedious. Image watermarking provides rigid security by authentication and copyright protection. There are different imagewatermarking techniques in Spatial and frequency domains. In this paper we are performing SVD transform along with frequency domain digital image watermarking methods like DCT and DWT for invisible watermarking. Comparison of thesame is done in terms of robustness and transparency to have a better idea of correlation of SVD. © Research India Publications.

Peptides are increasingly used as inhibitors of various disease specific targets. Several naturally occurring and synthetically developed peptides are undergoing clinical trials. Our work explores the possibility of reusing the non-expressing DNA sequences to predict potential drug-target specific peptides. Recently, we experimentally demonstrated the artificial synthesis of novel proteins from non-coding regions of Escherichia coli genome. In this study, a library of synthetic peptides (Synpeps) was constructed from 2500 intergenic E. coli sequences and screened against Beta-secretase 1 protein, a known drug target for Alzheimer’s disease (AD). Secondary and tertiary protein structure predictions followed by protein–protein docking studies were performed to identify the most promising enzyme inhibitors. Interacting residues and favorable binding poses of lead peptide inhibitors were studied. Though initial results are encouraging, experimental validation is required in future to develop efficient target specific inhibitors against AD. © 2015, Springer Science+Business Media Dordrecht.
