Out of several generalizations of fuzzy set theory for various objectives, the notions introduced by Atanassov (1983) and Atanassov and Gargov (1989) in defining intuitionistic fuzzy sets and interval-valued intuitionistic fuzzy sets are interesting and very useful in modeling real life problems. Ranking of interval-valued intuitionistic fuzzy sets plays a vital role in decision-making, data analysis, artificial intelligence and socioeconomic system and it was studied in Xu (2007c), Xu and Chen (2007a) and Ye (2009). In this paper a new method for ranking interval-valued intuitionistic fuzzy sets has been introduced and studied. The method is illustrated by numerical examples and compared with other methods. And then a new method for handling multi-criteria fuzzy decision-making problems based on interval-valued intuitionistic fuzzy sets is presented in which criterion values for alternatives are interval-valued intuitionistic fuzzy sets. The method proposed here can provide a useful way to efficiently help the decision-maker to make his decision. An illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness. © 2010 Elsevier Ltd. All rights reserved.

Fish and Shellfish Immunology | Year: 2012

The effects of dietary Pseudomonas aeruginosa VSG-2 supplementation on innate immunity and protection against Aeromonas hydrophila infection were evaluated in Labeo rohita. Fish were fed for 60 days with control diet or 3 experimental diets containing P. aeruginosa VSG-2 at 10 5, 10 7, and 10 9 cfu g -l, respectively. Various innate immune parameters were examined at 30 and 60 days post-feeding. Fish were challenged with A. hydrophila 60 days post-feeding and mortalities were recorded over 10 days post-infection. Dietary supplementation of P. aeruginosa VSG-2 significantly increased serum lysozyme and alternative complement pathway (ACP) activities, phagocytosis, and respiratory burst activity in head kidney macrophages of L. rohita throughout the experimental period. Superoxide dismutase (SOD) activity significantly increased after 60 days in the groups fed diets containing 10 7 and 10 9 cfu g -1 P aeruginosa. Serum IgM levels were significantly higher in the treatment groups than in the control group after 30 days of feeding; however, the opposite result was observed at 60 days. Moreover, fish fed diets containing 10 7 and 10 9 cfu g -1 P. aeruginosa had significantly higher post-challenge survival rates against A. hydrophila infection. Further, P. aeruginosa VSG-2 was found to be safe for mammals. These results indicate that dietary P. aeruginosa VSG-2 supplementation at 10 7 cfu g -1 can effectively improve innate immunity and disease resistance in L. rohita. © 2012 Elsevier Ltd.

Labeo rohita fingerlings were fed for 60 days with basal diet (BD) or one of the following experimental diets: DI (BD + B. subtilis); DII (BD + B. subtilis + L. plantarum); DIII (BD + B. subtilis + P. aeruginosa) and DIV (BD + B. subtilis + P. aeruginosa + L. plantarum). Various growth and immune parameters were examined at 30 and 60 days postfeeding. The fish group fed DIV diet had better improvement (P < 0.05) in weight gain, specific growth rate (SGR) and feed conversion ratio (FCR) than the control and other treatment groups. The serum lysozyme activities, alternative complement pathway activity, phagocytic activity and respiratory burst activity in head kidney macrophages of L. rohita increased significantly in the experimental groups throughout the trial period. Superoxide dismutase increased significantly in the experimental groups, except DI fed group, after 60 days of feeding. A significant improvement in serum IgM level was observed in the treatment groups at 30 days of feeding only. Further, fish fed the DIV diet had highest (P < 0.05) postchallenge survival rate (86.6%), followed by DII (73.3%) and DIII (66.6%) against A. hydrophila infection. Considering these promising results, we suggest that a multi-species probiotic supplementation in equal proportions for 60 days can effectively improve growth and immunity of L. rohita. © 2013 John Wiley & Sons Ltd.

In free-space optical link (FSOL), atmospheric turbulence causes fluctuations in both intensity and phase of the received beam and impairing link performance. The beam motionisone of the main causes for major power loss. This paper presents an investigation on the performance of two types of controller designed for aiming a laser beam to be at a particular spot under dynamic disturbances. The multiple experiment observability nonlinear input-output data mapping is used as the principal components for controllers design. The first design is based on the Taguchi method while the second is artificial neural network method. These controllers process the beam location information from a static linear map of 2D plane: optoelectronic position detector, as observer, and then generate the necessary outputs to steer the beam with a microelectromechanical mirror: fast steering mirror. The beam centroid is computed using monopulse algorithm. Evidence of suitability and effectiveness of the proposed controllers are comprehensively assessed and quantitatively measuredin terms of coefficient of correlation, correction speed, control exactness, centroid displacement, and stability of the receiver signal through the experimental results from the FSO link setup established for the horizontal range of 0.5 km at an altitude of 15.25 m. The test field type is open flat terrain, grass, and few isolated obstacles. © 2014 Optical Society of America.

Response surface methodology (RSM) is used to optimize the process parameters for the extraction of chromium from aqueous solution of waste sodium dichromate recovered from the pharmaceutical industry wastewater using emulsion liquid membrane technique. The liquid membrane used was composed of kerosene oil as the solvent, SPAN-80 as the surfactant and potassium hydroxide as internal reagent and trioctylamine as carrier. The process parameters namely, feed concentration, pH, internal reagent concentration and surfactant concentration on the extraction of chromium were optimized using Box-Behnken design. The optimum conditions for the extraction of chromium (VI) were: feed concentration (224.04 ppm), pH (2.76), internal reagent concentration (0.71 N) and surfactant concentration (1.92%, w/w). At the optimized condition the maximum chromium extraction was found to be 92.50%. © 2009 Taiwan Institute of Chemical Engineers.

The rapid development of networks such as internet, intranet, wireless communication etc., and multimedia techniques has emphasized on the need for copyright protection, authentication and identification and secret sharing of information. Visual cryptography is a secret sharing scheme where a secret binary image (SI) is encoded into n shares of random binary patterns. If the shares are xeroxed onto transparencies, the secret image can be visually decoded by superimposing a qualified subset of transparencies, but no secret information can be obtained from the superposition of a forbidden subset. The binary patterns of the shares, however, have no visual meaning and hinder the objectives of visual cryptography. Extended visual cryptography was proposed recently to construct meaningful binary images as n shares using hypergraph colorings, but the visual quality is poor. In this paper, a novel technique named visual secret sharing scheme using halftoning is proposed to achieve visual cryptography via halftoning. Based on the blue-noise dithering principles, the proposed method utilizes the void and cluster algorithm to encode a secret binary image into n halftone shares (images) carrying significant visual information. The simulation shows that the visual quality of the obtained halftone shares is observably better than that attained by any available visual cryptography method known to date. ©2010 IEEE.

DNA methylation is critical for gene silencing and is associated with the incidence of many diseases, including cancer. Underlying molecular mechanisms of human diseases and tissue-specific gene expression have been elucidated based on DNA methylation studies. This review highlights the advantages and drawbacks of various methylation screening techniques: blotting, genomic sequencing, bisulfite sequencing, methylation-specific PCR, methylated DNA immunoprecipitation, microarray analysis, matrix-assisted laser desorption ionization time-of-flight mass spectroscopy, nanowire transistor detection procedure, quantum dot-based nanoassay, single-molecule real-time detection, fluorimetric assay, electrochemical detection, and atomic force spectroscopy. The review provides insight for selecting a method or a combination of methods for DNA methylation analysis. Convergence of conventional and contemporary nanotechniques to enumerate methylation at specific CpG sites of oncogene would fill the gap in diagnosis of cancer.

The study evaluated the effects of dietary doses of Lactobacillus plantarum VSG3 on the growth performance, immunity, and disease resistance of Labeo rohita juveniles against Aeromonas hydrophila infection. Fish (mean body weight 60 g) were fed with diet containing 0 (control), 106, 108, 1010 cfu g-1 L. plantarum VSG3 for 60 days. Various growth and immune parameters were examined at 30 and 60 days of post-feeding. Fish were challenged with A. hydrophila 60 days post-feeding and mortalities were recorded over 10 days post-infection. Results showed that administration of VSG3 for 60 days had significant effects (P < 0.05) on the specific growth rate (SGR) and feed utilization efficiency of L. rohita. Dietary administration of L. plantarum VSG3 significantly increased the serum lysozyme and alternative complement pathway (ACP) activities, phagocytosis and respiratory burst activity in L. rohita throughout the experimental period. The highest superoxide dismutase (SOD) activity (P < 0.05) was observed in the fish group fed diet containing VSG3 at 108 cfu g-1. The serum IgM levels were significantly higher in the experimental groups compared to the control group after 30 days of feeding; but, the result was opposite after 60 days of feeding. Further, fish fed the diet containing 108 cfu g-1 L. plantarum VSG3 had significantly higher (P < 0.05) post-challenge survival rate (77.7%). These results collectively suggest that dietary supplementation of L. plantarum VSG3 at 108 cfu g-1 to L. rohita is optimal for enhancing the growth, immunity, and disease resistance against A. hydrophila infection. © 2012 Elsevier Ltd.
