A Multi-Quadrant, Integrated and Secure Model of Multiple Watermarking
Abstract: Watermarking safeguards the copyright of digital images with its original owner. A watermarking model is projected by conjoining three distinct multiple watermarking approaches. The secure model is obtained by integrating multiple watermarking with the latest secure cryptographic algorithms. The proposed model will improve copyright protection, achieve large embedding capacity and provide a stronger association amongst image and watermark for integrity and authentication. The multiple watermarking model partitions the cover image …

Experimental Analysis of the Effect of Fine Milled Husk of Rice as a Novel Filtration Control Agent for Water Based Drilling Fluid System
Abstract: Drilling operation is a complex process that requires integration of various engineering systems. As the drilling continues, the formation encountered offers challenges to wellbore integrity as pressure increases with depth. The influx of formation fluid is contained by the overbalance provided by weighted drilling fluid column. Another critical function of the mud is to restrict the filtration fluid lost to the formation by forming a suitable mud-cake around the wellbore. …

Comparative Analysis of Digital Image Watermarking using DCT and DWT
Abstract: AbstractWatermarking is a technique to hide information into digital data and provides security against intentional and unintentional attack. It is a very important and emerging field which helps to protect ownership of digital information. Watermarking is the process of inserting or hiding information behind cover data. In this paper we discussed about two digital watermarking techniques, Discrete Cosine Transform (DCT) and discrete wavelet Transform (DWT). The parameters to test robustness …

Community Participation in the Mitigation of Geogenic Fluoride Contamination in Drinking Water: A West Bengal Model
Abstract: Abstract The water management issue is by no means an issue only for experts. The close linkages between community initiatives in mitigation approach and grass-root level technology transfer can bring a sea-change in the drinking water management in rural communities. The conventional set up of sectoral water management institutions is hardly capable of coping with the drinking water management in the rural areas. A wiser drinking water management calls for …

A Ponder & Sedulousness Of Legion Shale Stabilizing Materials In Aqueous Based Drilling Fluid During The Process Of Borehole Strengthening
Abstract: Drilling fluid used while drilling the layers of shale will have the potential of reacting with water which tends to increase stickiness, induce swelling and promote sloughing of the borehole. This results in the reduction of drilling fluid circulation, increased mud loss, increase in torque and drag, reduction in lubricity. This will ultimately result in the increase of Non-Productive Time (NPT) during drilling which in turn increases Capital Expenditure (CAPEX) …
