In the present competitive business scenario vast amount of consumer reviews are written on Web about any product or service. WWW contains an overwhelming volume of customer reviews about different categories of commodities avail. The advent of social media and ecommerce has brought the era of a new age business and its customer base is growing exponentially every year. In today’s world, the online market is increasingly getting popular and it becomes more and more important to help the customer get the best product by all parameters. The quality of a product is best confirmed by taking the customer reviews from those who are already using that. All popular shopping websites like Amazon, flipkart, ebay etc. allow customer reviews once the product has been purchased. These reviews are such huge in numbers on these websites that it is not possible for a customer to consider them all. This paper focuses on extracting the features from product reviews taken from amazon.com or ebay.in sites given by reviewers to state their opinions. This is done at aspect level of analysis using ontology. Then it determines whether they are positive or negative thereby giving a scaling system to identify the effectiveness of a product. So, we propose a technique here, Sentiment Analysis for Product rating through Ontology (SAPRO). This technique performs text mining techniques on the customer reviews obtained from any of these websites and calculates the rating for this product (out of 5), to establish the like-ability of the product by the existing customers. SAPRO considers the end users’ perspective while addressing the Sentiment Analysis problem. The research uses a combination approach of domain ontology and Stanford dependency relation which intends to enhance the sentiment classification. The proposed technique is programmed in Java 8 programming language taking review data from the Amazon website as the dataset which is in JSON format. The results show that the review rating calculated by the proposed technique has 91% similarity with the existing ratings from the customers. The difference is mainly because the customer gives discrete numeric ratings but explains his sentiment better in words. The results when compared to base research by Arindam Chaudharyet. al [24], clearly show that the proposed technique(91% accuracy) is better than base technique(80-88% accuracy) for reviews.

finding useful patterns from large sets of data has brought new possibilities and insights which are unnoticeable to the human eye. But this is all possible only when we know what data it is i.e., when we have information about the metadata of the database under consideration. This paper aims to automatically identify table headers and their datatypes without any human intervention. Upon identification, this paper also implements a strategy to automatically import the data into a big data tool, SAS, to conduct further data analytics. These strategies are perfectly consistent even with a table with headers as it saves the time of the user who would otherwise manually map the fields.

Software defect prediction aims to determine whether a software module is defect-prone or non-defect prone by building prediction models. The performance of such models is liable to the high dimensionality of the datasets that may include irrelevant and redundant features. Adding feature selection reduces datasets with fewer features and maintains or improves the prediction capability over the original datasets. The performance of these feature selection method is evaluated using three popular classification techniques: Multilayer Perceptron, PART, J48 over four software defect-datasets obtained from the NASA data repository. The performances were measured using Accuracy, F-measure. Our results demonstrated that J48 combined with principle component analysis feature selection gives better accuracy and F-Measure for all datasets.

Analysis of problems means problem rises during the assembly of wheel cylinder. I completed various projects during training of 1 year. Some of the projects are included in this report such as, a) Concept of mechanical bleeder screw poka yoke, b) Time saving fixtures, c) Modification in design of rejection bin etc. In production assembly line, because of wrong bleeder size, many times the expensive tools will be breakdown. Because of this production will be stop for 1 to 2 hours. After the analysis of problem and implementation on line, problem gets solved and we achieved reduction in percentage of tool breakdown. When the model of wheel cylinder assembly is change for assembly process, fixtures of wheel cylinder also changes. For changing this type of fixtures, all nuts and bolts will be open and closed for all 8 stations. In this process the large time will be waste which is nearly equal to15 to 20 minutes. Therefore we will provide one design of fixture which automatically changes within two to three minutes. Due to this process and design we should save ten to fifteen minutes. We should also change the design of rejection bin. Previously the rejection bin used in industry is rectangular in shape, which contains the rejected wheel cylinder bodies. When the machine put this body in rejection bin, bodies will strike highly to the surface of rejection bin. The reason behind that, there would be fifteen cm distance between the rejection bin and rejection putting machine i.e. Gripper. After striking the job on the rejection bin, it will damage the surface of wheel cylinder. Also because of this sometime blow hole will appear on it. Due to this, the wheel cylinder jobs will repeatedly goes on rejection and it will damage completely. After the analysis of problem and implementation on modification of rejection bin we will definitely reduce the quantity of blow hole wheel cylinder jobs.

Aquaplaning or hydroplaning by the tires of a road vehicle occurs when a layer of water generates between the tires of the vehicle and the road, foremost to a damage of traction that avoids the vehicle from returning to control. If it happens to all wheels concurrently, the vehicle becomes, in consequence, an uncontrolled sled. The grooves of a tire are designed to separate water from underneath the tire, as long as high friction even in wet conditions. Aquaplaning or hydroplaning occurs when a tire come across more water than it can disperse. In this work we are going to do a CFD simulation of tire on a wet road conditions by using some technical parameter.

Concrete is a building material composed of a mixture of cement, water and aggregates with or without chemical admixtures. Now a day's sand is becoming a very scarce material, in this situation research began for inexpensive and easily available alternative material to natural sand. Although aggregates make up three fourths of the volume of concrete, the active constituent of concrete is cement paste [5]. The properties and performance of concrete are largely determined by the properties of the cement paste. In order to obtain workable concrete without strength loss, chemical admixtures such as super plasticizers are added in fresh mix of normal concrete. Super plasticizers in concrete confer some beneficial effects such as acceleration, retardation, air entrainment, water reduction, plasticity etc., and these effects are due to their action on cement [5]. It is important to find the optimum dose of Super plasticizer in order to minimize the trials and labor which leads to know the compatibility in different brands of cement. The experimental tests to determine the Physical properties of Concrete for M30 grade are studied and the results are compared among them. An attempt has been made in this paper to fully replace natural sand by Processed Slag (PS) sand and also partially replace with Processed Slag sand (50%) and Manufactured sand (50%). And also to decide the optimized dosage of Super plasticizers in fresh mix of normal concrete. For all the mixes, an addition of super plasticizer of about 0.5, 0.75 and 1.0% of cement content is used for a fixed water cement ratio. In this paper three different brands of cement namely Birla super, Ramco and Zuari and also two different brands of super plasticizers namely Glenium B233 and Conplast SP430 are selected for the test procedure. The investigations are to be carried out using several test which include workability test, compressive strength test and split tensile strength test.

In the most recent two decades, machine learning examination and practice has concentrated on cluster adapting for the most part with little datasets. In cluster taking in, the entire preparing information is accessible to the calculation, which yields a choice model in the wake of handling the information in the end (or the vast majority of the circumstances) various circumstances. The method of reasoning behind this practice is that illustrations are created indiscriminately as needs be to some stationary likelihood conveyance. Most learners utilize a ravenous, slope climbing look in the space of models. The advancement of data and correspondence advances drastically changes the information gathering and handling techniques. Progresses in scaling down and sensor innovation prompt to sensor systems, gathering point by point spatio-fleeting information about the earth. Straightforward articles that encompass us are changing from static, lifeless items into versatile, responsive frameworks with the possibility to end up distinctly more valuable and proficient. Brilliant things connected with all kind of systems offers new obscure potential outcomes for the improvement and self organization of groups of canny conveying machines. The dynamic qualities of information streaming after some time requires versatile calculations. While the dialects used to speak to speculations from cases are surely knew, cutting edge information mining calculations ought to mind, in any event, about the cost-execution management; the confinements in working in an open-world that infers impediments in the learning about the learning objectives and the constraints in all parts of computational assets. Every one of these perspectives requires observing the advancement of learning procedure itself, and the capacity of thinking and finding out about it. The information from Data Warehouse segment are bolstered into the Oracle BI server. Prophet Bi server gives productive preparing of information and structure data shrewdly.

In thermodynamics, exergy of a system is the maximum useful work possible during a process that brings the system into equilibrium with a heat reservoir. In case the surrounding is the reservoir, exergy is the potential of a system to cause a change as it achieves equilibrium with its environment. Exergy, in other words, is the energy that is available to be used. As energy analysis is based on the First law of Thermodynamics, it has some inherent demerits like not accounting for properties of the system environment, or degradation of the energy quality through dissipative processes. Also, it doesn't characterize the irreversibility of the processes within the system. In contrast, it characterizes work potential of the system. This is when the exergy analysis comes into play. It represents a good standard to estimate the maximum obtainable work from a given form of energy using the state of the surrounding as reference point. Exergy analysis, however, isn't a substitute for first law analysis. Rather, it is a supplement. Various researchers have conducted a thermodynamic analysis of a subcritical boiler-turbine generator under varying parameters of pressure, temperature and flow rate, in order to determine the ways to enhance plant efficiency. Also, the data on exergy loss distribution manifests that boiler and turbine irreversibilities account for the highest exergy losses in the power plant. Therefore, efforts at improving the power plant performance should be directed at improving boiler efficiency, since this will lead to maximization of plant efficiency. Another scholar, in his research, found that sliding pressure operation is better than constant pressure operation at part loads due to reduced throttling losses at part-load operation. Also, a large reduction in rate of exergy destruction has been observed for turbine. Hence, turbine should be operated at varying pressure at part load in order to maximize its efficiency.
