A Comprehensive Survey on Pest Detection Techniques using Image Processing

Abstract: Agriculture is an essential source of sustenance In India, this sector has tremendous opportunities of large-scale employment for villagers A survey report illustrated the dependency of the Indian population on agriculture ie nearly 70% Here, agriculture consist of the composition of several crops depending on the climatic nature However, most of the Indian farmers are still unaware of technical knowledge such as what kind of crop suits their farmland Numerous heterogeneous diseases affect the production of crops and result as a profitable loss This paper illustrates the pest diseases specifically with their impact on the current production of the crop In addition, it shows the survey reports based on several detection techniques of image detection It is important to search and develop more techniques in order to identify the pest disease before it creates a serious loss in crop production The current method for the reduction of pest disease is to spray pesticides However, this process severely affects the health of humans directly or indirectly The pest detection techniques at the early stages can provide less need for spraying pesticides The image detection technique emerges as an effective measurement tool in order to fight the infestation This technique offers better crop management with production as it delivers the maximum protection to crops Such techniques also minimize human errors and efforts as providing the feature of automatic monitoring over large fields

Marichev-Saigo-Maeda fractional calculus operators, Srivastava polynomials and generalized Mittag-Leffler function

Abstract: The aim of this paper is to evaluate four theorems for generalized fractional integral and derivative operators, applied on the product of Srivastava polynomials and generalized Mittag-Leffler function. The results are expressed in terms of generalized Wright function. Further, we also point out their relevance with the known results.

Performance Analysis of Grid-Connected 10.6 kW (Commercial) Solar PV Power Generation System

Abstract: In this paper design aspects and performance of a rooftop grid-connected solar photovoltaic power plant (RTGCSPVPP) has been studied. The RTGCSPVPP is installed at Gauri Maternity Home Ramkrishna Puram Kota Rajasthan, India for supplying the energy to whole hospital building. It was observed under a certain period of time during May 2017. Power output and other parameters such as economic parameters which affect the feasibility of a PV plant as payback period, net present value, life cycle conversion efficiency, environmental related parameters as CO2 mitigation and earned carbon credits were calculated. Total energy demand and monthly energy consumption of previous one year of the site was assessed and analyzed for base load calculation and design. The outcome shows the financial viability and possible reduction of burden on conventional energy sources. The grid-connectivity of PV plant made through a net-metering system which supplied energy to the grid when power generation is more than its demand and receives the energy during low power generation.

Performance evaluation of diesel–additives ternary fuel blends: An experimental investigation, numerical simulation using hybrid Entropy–TOPSIS method and economic analysis

Abstract: Research in the field of alternative, clean and renewable bio-fuels has increased dramatically in recent years for performance improvement, emission control and running cost reduction in internal combustion engines due to continuously increasing prices of conventional fuels, depletion of fossil fuels and environmental protection. In this work, a direct injection VCR diesel engine was used in experimental investigations for determining the combustion characteristics of D–NM–DEE blends at different compression ratios. By exhaust emission and performance analysis of the diesel engine at peak load and standard compression ratio (18.5), D–NM2.5–DEE7.5 (nitromethane 2.5%, diethyl ether 7.5% and diesel 90%) blend was identified as the best fuel blend among all fuel blends and pure diesel. Furthermore, all the considered fuels with different CR at peak load were ranked by the Entropy–TOPSIS method. From the analysis, D–NM2.5–DEE7.5 at CR–19.5 (ranked first with RC i - 0.922231) was found as the best fuel blend among all fuel blends and different compression ratios considered with similar experimental conditions. By the comparison of the best fuel blend (D–NM2.5–DEE7.5 at CR 19.5) with pure diesel (at standard CR 18.5), a significant improvement in engine performance, and reduction in emission and fuel cost was achieved.

Model order reduction by integral squared error minimization using bat algorithm

Abstract: In this paper, a large order system is reduced by using the bat algorithm to a reduced-order approximant The numerator and denominator coefficients of a desired reduced-order system are optimized based on integral square error minimization as an objective function pertaining to a unit-step as input The efficacy of the proposed method is tested with three test systems to get a corresponding reduced-order system The results are satisfactory in terms of minimum error with the proposed method as compared to Routh-Pade approximation and weighted-sum multiobjective harmony search based reduced models
