problem statement: Digital image watermarking is the most popular method for image authentication, copyright protection and content description. Zernike moments are the most widely used moments in image processing and pattern recognition. The magnitudes of Zernike moments are rotation invariant so they can be used just as a watermark signal or be further(More)
A field experiment was conducted to evaluate photosynthetic efficiency along with different growth parameters of aromatic rice genotypes. Forty genotypes including three non-aromatic checks exhibited enormous variations for leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR), grain yield, total dry matter,(More)
A condensation reaction between quaternary ammonium halide and sulfonate was first successfully applied to the synthesis of the chiral polymers. Reaction of bis(quaternary ammonium halide) with disulfonate afforded a polymer containing ionic bonds in its main chain. The chiral ionic polymers were applied to the asymmetric benzylation of(More)
The study was conducted to see the feasibility of raft aquaponics in polyculture pond. Three experimental ponds (with an area of 5.2, 3.12 and 3.12 decimal) were selected where the third one was considered as control pond. Locally available cheap materials were used in preparing rafts, e.g., bamboo splits, iron wire, plastic thread and disposable plastic(More)
A generalizes model presenting the sandwich beams was developed to calculate the flexural rigidity and sandwich beams dynamic characteristics. Different cases such as sandwich beams multi layer cores, sandwich beams multi cells, sandwich beams with holes in its cores having different shapes and different orientations were investigated. The finite element(More)

Crop duration of a rice plant, essentially dictated by flowering response, is an important selection criterion. It is determined by the interaction of genotype and environment. A field experiment was conducted with 40 rice genotypes to assess the fluctuation and/or stability of crop duration in a series of 16 environmental conditions. The effects of(More)
