Corrosion inhibition of mild steel by Capsicum annuum fruit paste
Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Chandan M. Reddy, Bhargav D. Sanketi, S. Narendra Kumar The anti-corrosive property of Capsicum annuum fruit paste (CFP) on mild steel was investigated. Weight loss and SEM analysis showed that the aqueous and ethanolic solutions of CFP exhibits excellent corrosion inhibition in 2M HCl. Contact angle, surface atomic composition and FTIR studies verified the presence of an organic film on the mild steel surface. The FTIR spectra also indicated the formation of active compound- Fe complex. CFP thus shows potential as an inexpen...

Experimental Analysis of Adiabatic Air-Water Two-Phase Flow Pressure Drop in Small Diameter Bends
Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): A.T. Autee, S.V. Giri Measurement of two-phase flow pressure drop and its prediction across curved tubes and bends is important for the enhancement of the performance and safety of the heat exchangers and flow transmitting devices. The comparative study of some of the available two-phase pressure drop correlations reveals that the predicted values of pressure drops by these leading methods may differ by large. The applicability of these correlations to the small diameter tubes of range 4.0-8.0mm and different bend angles of the...

Self-Adaptive Image Processing Using Blind Image Quality Assessment Technique
Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): K.S. Prasada Kumari Image processing techniques for filtering noise is a major challenge for DSP Engineers. When the images are corrupted by noise whose characteristics cannot be evaluated apriori, processing systems need to be flexible and adaptable. General purpose filters based on assumptions about image noise models fail to meet the quality and performance criteria in dealing with unmodeled noise. At the same time, evolutionary algorithms based adaptable filter architecture is proved to be successful in this regard. While exi...

Performance evaluation of hyperspectral classification algorithms on AVIRIS mineral data
This study uses three statistics namely Spectral Discriminatory Probability (SDPY), Spectral Discriminatory Entropy (SDE) and Spectral Discriminatory Power (SDPR) to assess the performance of various similarity measures. Similarity measures chosen are Spectral Angle Mapper (SAM), Spectral Information Divergence (SID), Jeffries–Matusita distance (JM) and their hybrid combinations of SAM-SID, SCA-SID, and JM-SAM. All the similarity measures and statistics were developed on MATLAB® platform and evaluated the same using freely available AVIRIS mineral data from U.S. Geological Survey spectral library. Analysis of statistica...

Physiochemical behavior changes during ripening in fruits of Trewia nudiflora Linn
Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Kapil Ghai, P.K. Gupta, A.K. Gupta Fruit ripening occurs with loss of fruit firmness and progressive degradation of the middle lamella and primary cell wall. The fruits of Trewia nudiflora Linn. were collected at different stages of fruit ripening and changes in physicochemical properties were determined. With ripening from immature green to fully ripe fruits, there was increase in fruit index with textural softening, loss of fruit firmness, decrease in cell wall polysaccharides as acetone insoluble solids and decrease in gal...
