So many of classification algorithms available in the data mining, we selected as few classification algorithms for heart disease prediction and found the accuracies. Different algorithms give various levels of accuracies. In the paper comparing the accuracies of few classification algorithms are Random Tree,Naives Bayes,Decision Tree and Random Forest then used K-Means clustering. The hungarian_csv, cleveland.csv and switzerland.csv heart disease data set received from UCI repository with 1272 instance and 14 regular attributes age, sex,cp, restbps, chol,fbs,restecg, thalach, exang, oldpeak , slope, ca, thalm, num were used here for analysis. Rapid miner studio software is a data science software platform developed by the company of the same name that provides an integrated environment for machine learning, data mining predicate analytics and business analysis. The different measures and result were tabulated and charted.

A considerable amount of waste heat in boiler flue gases is in the form of latent heat of water vapor. This energy cannot be recovered until the flue gases are cooled to a temperature below the dew point. These economizers are currently being used commercially for this purpose in a wide range of applications. Performance is dependent upon application-specific factors affecting the utility of recovered heat. Condensing economizers can also capture flue gas particulates. In this paper, the primary focus is on introduction of condensing economizer's for efficiency improvement of natural gas fired boiler. The secondary focus of this paper is to reduce or to control the particulate emission from natural gas fired boiler.

The main objective of the research work is to optimize the location and size of opening (hole) in a pressure vessel cylinder and hemi sphere dish end using ANSYS. Analysis is performed for three thick-walled cylinders and hemi spheres with internal diameters 20, 25 and 30 cm having 30 cm height (cylinder) and wall thickness of 20 mm. It is observed that as the internal diameter of cylinder increases the Von Misses stress increases. Optimization of hole size is carried out by making holes having diameter of 4, 8, 10, 12, 14, 16 and 20 mm located at center in each of the three cylinders and Hemispheres, and it is observed that initially Von Misses stress decreases and then become constant with hole size. Lastly, optimization of location of hole is carried out by making a 14 mm hole located at 1/16, 1/8, 2/8, 3/8 and 4/8 of cylinder height from top in all the three cylinders, and different angles like 10 0 , 30 0 , 45 0 , 60 0 & 90 0 on Hemisphere dish end.

They provide primary heat for a thermoelectric generator, engine intake air pre-heating and airconditioning and their capacity and efficiency is dependent on the material, shape, and type of the heat exchanger. Four different exhaust heat exchangers were designed within the same shell, and their computational fluid dynamics (CFD) models were developed to compare heat transfer and pressure drop in typical driving cycles for a vehicle with a 1.2 L gasoline engine. And two different materials (carbon steel and AISI4140) were applied to shell. Both the materials are best suited for manufacturing of heat exchanger, with reliable properties. These are the engineering materials that are helpful and playing a vital role in extraction of maximum heat from the exhaust of the engine. The result showed that the serial plate structure enhanced heat transfer by 7 baffles and transferred the maximum heat of166.358kw and maximum pressure drop of 9.2712kpa in a suburban driving cycle. Modeling of shell and all the structures were done in PTC-CREO and simulations were done in ansys FLUENT 15.0.

Studies have proved that majority of the customers decide their purchases inside the store due to the in store stimuli, and sometimes because of customer's personality traits. Personality is the set of characteristics or traits which differentiateindividuals among them and elicit certain reactions to the stimuli coming from the environment. The individual traits of a customer influences his/her perception of visual merchandising elements this can arouse customer in-store merchandise explorationor interaction with products/environment which encourages their purchase intentions. However, the combination of topics, visual merchandising and personality traits remains relatively unexplored. Hence, the present study aims to explore the relationship between big five personality traits extraversion, Openness, conscientiousness, Agreeableness, Neuroticism and specific impulse buying cues (Visual merchandising) namely Window display, Product display and signage display.A Survey was administered using a structured questionnaire among 250 women shoppers visiting retail outlets at various shopping malls in different parts of Bangalore.The results of the study indicatedthat there is significant difference in impact of personality traits on evaluation of store/mall in terms of visual merchandising.

The three Telugu POS taggers are improve the accuracy of existing Telugu POS taggers by using an voting algorithm. viz., (1) Rule-based POS tagger (2) Brill Tagger (3) Maximum Entropy.POS taggers are developed with an accuracy of 97.014%, 93.248%, and 85.914 respectively. An annotated corpus of 14000 words is used to train the last two taggers. To improve the accuracy of these taggers, an error analysis is made to find out the errors made by these three taggers and methods are then examined. As a first step, a voting algorithm is proposed to get better results to build an ensemble Telugu POS tagger. This tagged output could be used for word sense disambiguation (WSD) is retrieving Telugu documents and a variety of NLP (Natural Language Processing) applications..

The detailed classification of these AC-DC boost converters have 4 categories with number of circuits and concepts has been carried out to provide easy selection of proper topology for a specific application. These AC-DC converters provide a high level of power quality at the AC mains, well-regulated and also free ripple isolated DC outputs. Moreover, these converters have been operated very satisfactorily with very wide AC mains voltage and frequency variations resulting in a concept of universal input..

Because of social media can make profit from them. Customer service is one of the major elements for making profit out of the customer. In this research, wehave tried to find out by this analysis how to customer service can help to made profit for social media. We have shown that how they could be improved customer service and provided customer satisfaction to build a strong customer relationship(Aghdaie, Tafreshi, & Behzadian, 2014; Madichie, 2014). Through the research, we have discussed the ways of improving customer relationship. This report was mainly showed how to social media could improve employees' skills and customer relationship management of apparel product.

Laravel is most advance and elegant PHP framework & it make the development process simple. It processes non-business logic on its own that allows programmers to focus on business logic of an application. It has three interconnected parts called Model, View and Controller. Model consist of data and business logic. A view uses Laravel's blade templating engine which works seamlessly with HTML for representation of information. Controller classes are used are used to organize the behavior of request handling logic. Related HTTP request handling logic can be grouped into controller class. With Eloquent ORM active record implementation is done for working with database. Each table in MySQL database has a corresponding model which is used to perform CRUD operations on it. Third party packages can be integrated easily into Laravel application by writing few artisan commands. These packages save tremendous amount of development time. Most of these packages are well tested, stable and available for free of cost.
