  This study introduces a new approach for prediction problem with the objective of attaining maximum classification accuracy with smallest number of features selected. Cardiac diseases are very common and one of the main reasons of death. According to a recent literature study by the Indian Council of Medical Research, about 25% of cardiac problems are between age group of 25-69 years. Hence, the main objective of this work is to predict the possibility of heart diseases at its early stages with less number of attributes. Our approach integrates anthropometric data and physiological data of cardiac diseases by proposing Novel Feature Selection method for prediction of heart diseases. The dataset used in this work is collected from Cleveland heart disease database. The results show the proposed approach leads to a superior feature selection process in terms of sinking the number of variable required and increased in classification accuracy for better prediction.

  Digital images and videos have become so important and are being used in a wide range of applications including digital cameras, Medical imaging, DVD, digital TV, HDTV and video telephony. These applications are feasible because of the advancement in computing and communication technologies as well as efficient image compression algorithms. Fast Cosine Transform (FCT) is widely used technique in image and video compression algorithms. FCT requires large amount of mathematical computations including memory access, multiplications and accumulations which leads to hardware complexity. The hardware complexity due to memory access can be reduced by the memory access reduction scheme called as MARS. As this Memory Access Reduction Scheme (MARS) is very much suitable for FPGA designs in this work, the 2D-FCT is proposed using MARS based architecture. Then existing architecture for 2D-FCT and the proposed MARS based 2D-FCT are simulated and synthesized in Virtex7-xc7v2000t-2flg1925 FPGA device using Xilinx ISE 14.1. The results of the Conventional 2D-FCT structure is compared with the proposed MARS based 2D-FCT to show the improvement in terms of hardware efficiency of the proposed work.

  The business case for work-life balance practices as embraced by numerous associations, lays on drawing in better candidates and decreasing work-life conflict among existing representatives keeping in mind the end goal to upgrade organizational performance. This present study gives some proof to support the idea that work-life practices improve performance by method for decreased work-life conflict. Totally, 250 women journalists of print media from Tamil Nadu, India was taken for the study. Researcher used judgmental sampling method to select samples for the study. The primary data for this study was collected from the women Journalists in Tamil Nadu with the help of well-structured questionnaire constructed based on dimension like demographics profiles, dimensions of work life balance and effectiveness of organizational performance. We propose that may be the print media in this way ought to be adjusted to mirror the quantity of extra courses by which work-life balance practices can impact organizational performance, including upgraded social exchange forms, expanded cost investment funds, enhanced profitability and decreased turnover. The effect of these procedures might, nonetheless, be affected by various components, including role conflict and role ambiguity, stress, gender differences, time management, social context, career advancement and managerial support.
