Perceptual video quality assessment in H.264 video coding standard using objective modeling

Since usage of digital video is wide spread nowadays, quality considerations have become essential, and industry demand for video quality measurement is rising. This proposal provides a method of perceptual quality assessment in H.264 standard encoder using objective modeling. For this purpose, quality impairments are calculated and a model is developed to compute the perceptual video quality metric based on no reference method. Because of the shuttle difference between the original video and the encoded video the quality of the encoded picture gets degraded, this quality difference is introduced by the encoding process like Intra and Inter prediction. The proposed model takes into account of the artifacts introduced by these spatial and temporal activities in the hybrid block based coding methods and an objective modeling of these artifacts into subjective quality estimation is proposed. The proposed model calculates the objective quality metric using subjective impairments; blockiness, blur and jerkiness compared to the existing bitrate only calculation defined in the ITU G 1070 model. The accuracy of the proposed perceptual video quality metrics is compared against popular full reference objective methods as defined by VQEG

Bitter Gourd (Momordica charantia) Peroxidase in Decolorization of Dyes from Tannery Effluent

Bitter Gourd (Momordica charantia) is a commonly available plant in India and its applications are limited to few medicinal properties in addition to being edible. The primary objective of this study is to evaluate the efficacy of Momordica charantia peroxidase in the degradation of dyes present in tannery effluents under various experimental conditions like pH, Temperature, Time intervals and Enzyme concentration on the basis of the one-factor-at-a-time (OFAT) method. The maximum decolorization was achieved at pH 5.0 – 6.0, 40oC temperature, in 4 hours with an enzyme concentration of 0.6 ml consisting of 4500 Units enzyme activity extracted from 0.5 g of Bitter Gourd. Present study results demonstrate that the Momordica charantia peroxidase is an effective biocatalyst for the treatment of effluents with dyes from tanning industries.ÂÂ

Application of a comfort index for evaluating tactile and thermo-physiological comfort properties of surgical gowns

146-153The primary objective of this study is to develop a mathematical tool to calculate a global desirability index value (comfort index) for disposable surgical gowns which will enhance the market value for the product. The mathematical tool is based on the desirability function approach, by using its different modules such as maximization, minimization, and target as per the objectives chosen. Three different disposable nonwoven surgical gowns, such as Fabrics C (44.35 g/m2, 0.32 mm thickness & 11 micron pore size), A (46.31 g/m2, 0.29 mm thickness & 10 micron pore size) & S (44.71 g/m2, 0.36 mm thickness & 8.9 micron pore size), intended for hospital application have been used. The developed model focuses on predicting tactile and thermophysiological comfort, by considering the importance of certain physical properties, leading to the comfort of the wearer. Results reveal that out of the three gowns, Fabric C gown fetches the best comfort index value of 0.5689 followed by the Fabric S and A gowns with the values of 0.3009 and 0.1969 respectively

Ensuring biological safety of drinking water at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh, India

Potability of drinking water from various sources at the campus of International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh, India had been assessed for 17 years (1994 to 2010). All four sources of drinking water at ICRISAT, including Manjeera water (Municipal corporation supplied drinking water), borewell 1, borewell 2 and ICRISAT water (mixture of both Manjeera as well as borewells after treatment), were tested for their potability once in two months by most probable number (MPN) method. The results indicated that water from borewells were not safe to drink without treatment as Escherichia coli was found in 10 and 12 years out of 17 tested years for bore wells 1 and 2, respectively. Manjeera water samples were also found unsafe in two out of the 17 years, whereas ICRISAT water was found safe to drink throughout the study period. This study indicated that even deep borewells (of about 135 ft) can get contaminated, and its water is not safe to drink without treatment, and an additional treatment of municipal water supply is required in order to have safe drinking water.Keywords: Potability, drinking water, Escherichia coli, borewell water, municipal wate
