Feature Selection Based on Bi-objective Differential Evolution
Das, Sunanda,Chang, Chi-Chang,Das, Asit Kumar,Ghosh, Arka Korean Institute of Information Scientists and Eng 2017 Journal of Computing Science and Engineering Vol.11 No.4
Feature selection is one of the most challenging problems of pattern recognition and data mining. In this paper, a feature selection algorithm based on an improved version of binary differential evolution is proposed. The method simultaneously optimizes two feature selection criteria, namely, set approximation accuracy of rough set theory and relational algebra based derived score, in order to select the most relevant feature subset from an entire feature set. Superiority of the proposed method over other state-of-the-art methods is confirmed by experimental results, which is conducted over seven publicly available benchmark datasets of different characteristics such as a low number of objects with a high number of features, and a high number of objects with a low number of features.

Gas holdup in tapered bubble column using pseudoplastic non-Newtonian liquids
Sumit Kumar Jana,Sudip Kumar Das,Asit Baran Biswas 한국화학공학회 2014 Korean Journal of Chemical Engineering Vol.31 No.4
Experimental studies on the gas holdup in two tapered bubble columns using non-Newtonian pseudoplasticliquid have been reported. The effects of different variables such as gas flow rate, liquid viscosity, bed height,and orifice diameter of sieve plate on gas holdup have been investigated. An empirical correlation has been developedfor the prediction of the gas holdup as a function of various measurable parameters of the system. The correlation isstatistically acceptable.

Chronic arsenicosis is a major environmental health hazard throughout the world, including India. Animals and human beings are affected due to drinking of arsenic contaminated ground water, due to natural mineral deposits, arsenical pesticides or improperly disposed arsenical chemicals. Arsenic causes cancer with production of free radicals and reactive oxygen species (ROS) that are neutralized by an elaborate antioxidant defense system consisting of enzymes and numerous non-enzymatic antioxidants. Dietary antioxidant supplements are useful to counteract the carcinogenesis effects of arsenic. Oyster mushroom lectins can be regarded as ingredients of popular foods with biopharmaceutical properties. A variety of compounds have been isolated from mushrooms, which include polysaccharides and polysaccharopeptides with immune-enhancing effects. Lectins are beneficial in reducing arsenic toxicity due to anticarcinogenetic roles and may have therapeutic application in people suffering from chronic exposure to arsenic from natural sources, a global problem that is especially relevant to millions of people on the Indian subcontinent.
