There has been a considerable debate on the applicability of conventional encryption techniques for protecting images. Chaos based encryption systems are preferred for digital image encryption for a long time now. For a reliable encryption method any alteration in image content or the key must be reflected in the cipher image. The present work demonstrates a highly secure and reliable encryption of...
Recommender systems these days tend to achieve status and importance. The algorithms and approaches present in a recommender system define the importance and worth of the recommender systems. Till now, the research which have been done has concentrated on generating the new approaches and algorithms so that by implementing them some good recommendations can be provided to the users. In this research...
Sentimental Analysis is one of the most popular technique which is widely been used in every industry. Extraction of sentiments from user's comments is used in detecting the user view for a particular company. Sentimental Analysis can help in predicting the mood of people which affects the stock prices and thus can help in prediction of actual prices. In this paper sentimental analysis is performed...
Penetration of media in financial market has changed the way of doing business, media, one of the most growing medium to exchange ideas & thoughts, which plays an important role in influencing thoughts of the investors which in turn affects market transactions figures and index values. Thus machine learning and sentiment analysis can be of great help in deducing the mood and psychology of people...
In the recent years Mobile Ad-hoc Network is emerging as a very popular technology in the wireless network. Because of its dynamic topology and its infrastructure less architecture, it is vulnerable to various types of attack. Providing security against the intruder is a challenging task in MANET. In this paper, we present the Modified Enhanced Adaptive Acknowledgment (EAACK) based Intrusion Detection...
Radio over Fiber (ROF) is an innovating technology that provides provision for the flourishment of broadband wireless service which combines robust transport technologies and flexible optical routing. ROF is an integration of wireless and fiber optic networks, which has a range of applications including last mile solutions, extension of existing radio coverage and capacity, etc. A Nematic type LCPCF...
We propose a nonparametric Bayesian, linear Poisson gamma model for count data and use it for dictionary learning. A key property of this model is that it captures the parts-based representation similar to nonnegative matrix factorization. We present an auxiliary variable Gibbs sampler, which turns the intractable inference into a tractable one. Combining this inference procedure with the slice sampler...
Problems encountered due to size reduction of transistor in fabrication of integrated circuits leads us to switch to a new paradigm, which uses these fundamental effects as working principles. Quantum-Dots are used as basic building blocks for this new paradigm. In this paper we discuss the implementation of a Look Up Table (LUT) using this Quantum-Dot Cellular Automata (QCA). The software used to...
