We report the experimental analysis of a pyramid solar still with boosting mirror system for increasing the distillate yield rate under clear climatic conditions in Coimbatore (11° N latitude), India. The radiation received by the still is boosted up by reflecting the solar radiation. A tracking system keeps track of incident radiation into the still. The area of the still is 0.25 m2. Water and ambient temperature are measured along with solar radiation and humidity at regular intervals of time. The inner and outer faces of the glass cover temperatures are also recorded. The average solar radiation received is 760.43 W/m2. The daily average efficiency of the still was found to be 15%. A 2.9 l/m2/d distillate yield is obtained with the help of the boosting mirror; whereas, 1.52 l/m2/day are collected without the boosting mirror. In this work an attempt has been made to study the effect of heat transfer within a pyramid solar still. The thermo physical properties of the still are analyzed for this study. Thermal conductivity dynamic viscosities of water are also studied for this system. The thermal conductivity is in the range of 26.77 x 10-2 Wm-2 C-1 to 29.64 Wm-2 C-1. Dynamic viscosity ranges from 18.6 x 10-6 Nsm-2 to 20.2 x 10-6 Nsm-2.Keywords

The credit card payment system is a widespread usable system which provides the easiest way of payment to the customers, but some of them misuse another individual's credit card for personal reasons. So, in order to provide credit card fraud detection, Multiple Semi-Hidden Markov Model is suggested to gather multiple observations and the detection phase is executed. It is significant to compute the good model parameters because it impacts the detection performance in the Multiple Semi-Hidden Markov Model. So, in this manuscript an innovative technique is introduced which is called Optimized Multiple Semi-Hidden Markov Model (OMSHMM) which is used for optimizing the model parameters. The Multiple Semi-Hidden Markov Model is used for detecting fraudulent users and for optimizing training values Cuckoo Search algorithm is proposed. The main intent of this research is automating the use of Multiple Semi-Hidden Markov Model, by liberating customers from the necessity of statistical knowledge. The number of states and also its model parameters are decided by the Cuckoo Search algorithm. An experimental result shows that when compared to the existing research there is high accuracy in the proposed research.Keywords

Coal production using surface miner technology is a well-accepted method today in Indian coal mines contributing a sizeable proportion to the overall production. Production of coal chips of desired size is an important parameter in surface miner performance evaluation in terms of tonnes per hour as well as fulfilment of the need of the consumers. The demand for an average chip size in the range 100-150 mm thermal power plants is growing and this size also fetches a premium price compared to blasted lumpy coal. A field study was conducted at Sonepur Bazari opencast mine, Eastern coalfields (ECL), West Bengal, India for evaluating the cutting operation and performance of a 2200 SM surface miner under varied operational and rock mass conditions. An imaging technique coupled with Fragalyst software was used for grabbing and analysing the sizes of chips produced by surface miner. The wide variation in chip size formation observed in the field was due to the fluctuations in cutting speed and also the presence of joints. This communications reports the study carried out on surface miner to develop a new methodology for characterizing chip size, fixing the optimum machine operating parameters for a desired chip size and also the production potential.Keywords

Applicability of a surface miner (SM) must be based on a careful assessment of intact rock and rock mass properties. A detailed literature review was made to identify different parameters influencing the performance of various types of cutting machines deployed in different parts of the world. The critical parameters influencing the production, diesel consumption and pick consumption of SM in Indian coal and limestone mines, were identified through artificial neural network (ANN) technique and screened by correlation coefficient analysis. Parameters that were common in both ANN and correlation analysis were grouped under critical category and others in semi-critical category.Keywords

Two accurate and precise methods were developed for the estimation of Cefixime and Erdosteine in its pharmaceutical dosage form. First method is area under the curve method; the areas under the curve in the range of 294.5-284.5 nm (for CEF) and 240.0-230.0 nm (for ERD) were selected for the analysis. Second method is first order derivative spectroscopy by solving simultaneous equation, 309.0 nm (for CEF) and 227.5 nm (for ERD) were selected for the analysis. In both the methods linearity for detector response was observed in the concentration range of 10-50 μg/ml for both Cefixime and Erdosteine. The proposed methods were successfully applied for the simultaneous determination of both drugs in its pharmaceutical preparation. The results of the analysis have been validated statistically and by recovery studies.Keywords

Three simple, precise and economical UV methods have been developed for the estimation of Tamsulosin in pharmaceutical dosage form. Tamsulosin has the absorbance maxima at 281.0 nm (Method A), and in the first order derivative spectra, showed sharp peak at 234.5 nm (Method B). Method C applied was area under curve (AUC), in the wavelength range of 286.0-276.0 nm. Linearity for detector response was observed in the concentration range of 5-25 μg/ml for all three methods. The proposed methods were successfully applied for the simultaneous determination of Tamsulosin in commercial pharmaceutical preparation. The results of the capsule analysis were validated statistically and by recovery studies. It was found to be satisfactory.Keywords

For analysis of image, dividing or grouping of objects in an image is important. The concept of grouping or dividing an object is said to be image segmentation. Image segmentation is used for image detection and classification processes. This article explains the image segmentation on satellite images using mathematical framework. Nowadays the satellite plays a major role in development of one nation through research. Images taken by satellites are used for many applications like weather forecast, study of geographical structures of regions and many more. The Mathematical framework based image segmentations are explained based on the satellite images.

Corporate Business & Industry are revisiting their own business processes and technology approaches as competitors and partners start to employ ‘digitalised’ business processes and exploit the increasing convergence between operational technology and information technology in the Corporate World. Technology solution providers are using concepts such as Internet of Things (IoT) to reach customers’ visibility and effectively at Point of Purchase (PoP) to sustain growth. Companies are creating and implementing the IoT solutions as alternative solutions to traditional technology solutions. Emerging business models allow Corporates to rethink or even outsource. Visibility by Advertising & Branding, Customer Retention by Intelligent connected systems along with network communications, software, and analytics now enable companies to improve and Turnaround Time (TAT) to optimise operating performance.Keywords

Flubendiamide, novel insecticide used for control of lepidopteron insects on agriculture crops in India. Flubendiamide exposure of to human and animals occurs through ingestion of contaminated feed/fodder, food-products and drinking water etc. Aim of the present study was to develop a simple HPLC method for flubendiamide estimation in blood plasma. Result indicated that HPLC estimation of flubendiamide in blood plasma shows linear standard curve in the range of 0.039-5.0 μg.ml-1 with correlation coefficient (R2) 0.999. Limit of Detection (LOD) and Limit of Quantification (LOQ) was 0.039 μgml-1. Intra-day, inter-day coefficient of variance and mean recovery were found to be 2.70%, 3.50% and approx. 100% respectively, by using C18 column and mixture of acetonitrile: water (70:30, v/v) as mobile phase with flow rate of 0.5 mlmin-1 at 210 λ. Result of this study concluded that this HPLC method is very simple, reliable and repeatable for flubendiamide estimation blood plasma.Keywords
