  • Big Data Analytics: Classification and Solution for Soil and Fertilizer System   Order a copy of this article
    by Raghu Garg, Himanshu Aggarwal 
    Abstract: Soil is one of the most important factors for the growth of plants. It carries various nutrients like water and certain contents of air which are essential for plant nourishment. At times over exposure becomes the root cause for the degradation of an otherwise fertile soil. In present times fertilizers are given the responsibility to maintain the productivity that we yield from the soil. The method prevalent to determine the quality of the soil is known as soil analysis. Soil analysis generates an estimation of the unstructured data through the process of examining the defined soil. The specimens of a wide spectrum of soils are tested in the laboratories in order to develop heaps of agricultural data. During our research work different machine learning algorithm using big data analysis are used to detect the fertilizer recommendation classes through defined soil nutrition composition. The reports are collected from Tata soil testing laboratories for experiment. Stochastic Gradient Descent (SGD) and Artificial Neural Network (ANN) are the classification methods that are compared in this paper. The performance measures inclusive of the accuracy and area under curve (AUC) are exercised to determine efficiency of classification model. Experiments show that the SGD performs a lot better then artificial neural network when it comes to accuracy, AUC and pace. The ANN is outdone by SGD with linear regression. The percentage of overall accuracy and AUC values of SGD are 88% and 86% respectively. The overall accuracy and AUC using ANN is 80% and 79% respectively. The results also reflect that SGD with linear regression are feasible in accurate recognition of the fertilizer recommendation classes.

    by Dipak Jadhav, M.M. Ghangrekar 
    Abstract: Single chamber microbial fuel cells (MFCs) made from ceramic pots, forming anodic chamber, were inoculated with different proportions (v/v) of Shewanella putrefaciens and mixed-anaerobic sludge, viz. 100:0% (MFC-1), 0:100% (MFC-2), 10:90% (MFC-3), 30:70% (MFC-4) and 50:50% (MFC-5). Performance of these MFCs was evaluated using different electrochemical analyses. Due to specific substrate-selectivity, MFC-1 showed lower power (1.22 W.m-3) than MFC-2 (2.15 W.m-3). Power performance increased from 2.21 (MFC-3) to 2.56 W.m-3(MFC-4) with increased fraction of S. putrefaciens from 10 to 30% in the inoculum, and power density further enhanced to 3.1 W.m-3 in MFC-5 inoculated with equal-fraction of S. putrefaciens and mixed sludge. Bioelectrochemical analyses showed higher electron transfer rate and lower charge-transfer resistance in MFC-5 due to synergy between both the inoculums and promoted the electron transfer rate at anode. Thus, inoculation of MFC with equal-fraction of mixed-anaerobic sludge and S. putrefaciens showed effective bio-augmentation to reduce the start-up time and to improve the anodic bioactivity and power generation from MFC.

    by Yan Zhang, Jian Yu, Yiying Fang, Sang-Bing Tsai, Quan Chen 
    Abstract: As China transitions towards high-quality economic development, exploring and improving the green transport efficiency of airlines on the premise of environmental constraints is important for the country's industrial transformation. In this paper, the slack-based model (SBM) and meta-frontier model were used to measure the efficiency and efficiency gaps of Chinese airlines from 2001 to 2016 under different, as well as identical production frontiers. The paper also analyzed the issue of inefficiency caused by the mismatch of airline factor inputs. The results showed that: first, the overall efficiency of airlines in China followed a W-shaped change; second, private joint-venture airlines had the highest efficiency and the efficiency increased relatively quickly; and, third, the allocation redundancy factor input was an important reason for the airline inefficiency, and obvious improvement was noted regarding issues pertaining to personnel redundancy and fuel consumption redundancy. Based on the research findings, countermeasures are proposed to improve the efficiency of airlines in China so as to achieve high-quality development.
