In Wireless networks, the security of data and information has important role in digital communication and multimedia communication. Different types of encryption algorithms have an important role to provide the security to the wireless networks. Cryptography basically used for the data confidentiality and privacy by making indiscernible. Hence the original data cannot be interrupted by the unauthenticated user. The encryption techniques and different types of useful algorithms are used to provide the more security to the applications. In this paper the well- known method chaotic algorithm is used. Chaotic algorithm is used in real time secure image transmission systems. This algorithm is very popular method used in Research for encryption and decryption process. The combination of chaotic theory and cryptography has very important role in Information Security. In this communication, a new image encryption algorithm based on chaotic map is proposed for gray scale 2D image. In this proposed algorithm, the plain or original image is taken which has MXN dimension. Then Redistribute the pixel pair wise by deciding.

The present paper deals with the performance modeling and simulation of the paper making system of a paper plant. The paper plant is a complex and repairable engineering unit which comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening and paper making etc. One of the most important functionaries of a paper plant is paper making system which is having four main subsystems. Considering the exponential distribution for the probable failures and repairs, the performance model has been developed with the help of mathematical formulation based on Markov birth-death process. Using probabilistic approach, the differential equations have been developed. Then these equations are further solved by using normalizing conditions so as to determine the steady state availability i.e. measure of performance of paper making system of a paper plant. The performance of each subsystem of the paper making system of a paper plant also has been analyzed for selecting the best possible maintenance strategies in a paper plant. So, the findings of this paper will be highly useful to the plant management for timely execution of best possible maintenance strategies and hence to enhance the system performance.

Stock market refers to the market where companies stocks are traded with both listed and unlisted securities. Indian stock market is also called Indian equity market. Indian equity market was not organized before independence due to the agricultural conditions, undeveloped industries and hampering by foreign business enterprises. It is one of the oldest markets in India and started in 18th century when east India Company started trading in loan securities. During post independence the capital market became more organized and RBI was nationalized. As we analyze the performance of stock markets in the last three decades, it comes near enough to a perfectly aggressive marketplace permitting the forces of demand and delivers an inexpensive degree of freedom to perform in comparison to other markets in particular the commodity markets. list of reforms undertaken seeing the early nineteen nineties include control over problem of capital, status quo of regulator, screen primarily based buying and selling and threat management. Latest projects include the t+2 rolling settlement and the NSDL was given the obligation to assemble and preserve an important registry of securities marketplace participants and experts. stock exchanges facilitates the purchase and sell of shares, debenture and financial securities . There are 19 stock exchanges all over India. all the matters and activities which effect the stock exchanges are controlled , directed and supervised by the governing body. Brokers are the most important intermediary in stock market. Stock market of India is governed by Securities contract regulation act 1986, SEBI act 1992 and depository system 1996. Commodities are a Bodily or digital market place for buying and selling and trading. They are of two types - tough and soft commodities, they are of two types - tough and soft commodities. The deposit structure, market share, BSE statistics and net worth requirements are expressed by various pie-charts and bar graphs.

A semi-classical Boltzmann transport model is developed to observe photon-assisted dynamics of induced carriers in the graphene nanoribbons. When the nanoribbons are subject to a multi-frequency Alternating Current (ac) field and superimposed on by static Direct Current (dc) field, an unusual non-linear response of the system shows up at a rather strong drive force. The non-linearity in the photo-current allows for up-conversion necessary for low-frequency oscillators. Regions of positive differential conductivity are observed paving way for graphene to be operated as a small signal amplifier for Terahertz (THz) applications. The fractional photon-assisted phenomenon is also observed when the stark factor r > 1 and the ratio of the n-th harmonic to stark factor takes on half-integer values.

The present study provides the health application at affordable cost. This study such as ethnomedicine keenly represents one of the best avenues in searching new economic plants for medicine.The present investigation was carried out to examine the qualitative phytochemical analysis, antibacterial and anti-oxidant effect of polyherbal drugs namely Shirishadi and Bharangyadi. The hydroethanolic extracts of drugs showed the presence of alkaloid, tannins, flavanoids, phlobatannins, saponins, terpenoids, cardiac glycosides, anthraquinones, proteins, amino acids and carbohydrates particularly reducing sugars. The estimations of total phenolics content in the selected groups was also done spectrophotometrically following the Folin – ciocalteau method and was found to contained 112mg/g & 50.98+ 0.62 of phenolics respectively. Flavonoids were also estimated following the aluminium chloride method and 13.66 + 1.67mg/g of flavonoids was found to present in Bharangyadi compound whereas Shirishadi contains 23.89 + 4.62mg/g. ABTS+ assay shows maximum inhibition of 82.27 ± 2.69 with EC50 462.72 ± 4.56 for Shirishadi and Bharangyadi shows 64.2+ 0.86 percent inhibition with EC50 675.31 + 4.24. Assessment of antimicrobial activity shows that Bharangyadi has more potent antibacterial and anti-fungal effect than Shirishadi. Antibacterial activity was best revealed by Bharangyadi compound against Plesiomonas shigelloides followed by Pseudomonas aeruginosa it showed strong antifungal property with maximum affinity against Candida parapsilosis. Shirishadi compound also showed effective antibacterial and antifungal activities with maximum inhibition zone against Plesiomonas shigelloides and Candida tropicalis.Both the drugs were tested against seven bacterial strains and four fungal strains.

This study analyses the effect of media exposure and perceived bias on performance rating of the Modi government that was elected in 2014 in India. A sample of Coimbatoreans (N = 210) was chosen for the survey. Results showed that media exposure had a positive and direct effect on performance rating, while bias had a significant but negative effect. Such perceived media bias also had an ability to alter the political affiliation of the people, which in turn affected the performance rating, positively. Political participation of the people also exerted a direct effect on public perception about media bias towards the ruling Modi government.
