This paper presents the results of a comprehensive interpretation to research some of the most commonly used encryption algorithms in the domain of cryptography firstly to identify as many of their weaknesses and vulnerabilities as possible, and secondly to identify the aspects of these weaknesses that can be avoided by correct implementation. Day by day the vulnerabilities are rapidly increasing on the Internet. A strong encryption algorithm is required to counter these vulnerabilities. In this paper, we provided the overview of existing conventional encryption algorithms and literature survey of these algorithms. This study extends to define a new secure conventional encryption algorithm in Cryptography. The algorithm takes data in intelligible form and converts it in to secure unintelligible form. © 2016 IEEE.

A five dimensional Kaluza-Klein dark energy model with variable EoS parameter is investigated in the scale co-variant theory of gravitation proposed by Canuto et al. (in Phys. Rev. 39:429, 1977) in a five dimensional Kaluza-Klein space-time in the presence of perfect fluid source. Using the special law of variation for Hubble's parameter proposed by Berman (in Nuovo Cimento B 74:183, 1983), we have obtained a determinate solution which represents a dark energy cosmological model in the theory. We have also used the result that the scalar expansion is proportional to shear scalar of the space-time. It is observed that the EoS parameter, skewness parameter in the model turn out to be functions of cosmic time. Some physical and Kinematical properties of the model are also discussed. © 2013 Springer Science+Business Media Dordrecht.

In order to build up a bridge between quality and productivity, the present study highlights optimization of turning process parameters to provide good surface finish as well as high hardness. The objective of this paper is to solve the multi-response parameter optimization problems of turning process. By applying Taguchi method the quality of manufactured goods, and engineering designs are developed by studying variations. In this work, an attempt has been made to solve the correlated multiple criteria optimization problem of turning process by considering the major performance characteristics hardness and surface roughness. The corresponding machining parameters are cutting-speed, feed and depth of cut. Traditional Taguchi based hybrid optimization approaches rely on the assumption that quality indices are uncorrelated or independent. But it is felt that, in practice, there may be some correlation among various quality indices (responses) under consideration. To overcome this limitation of Taguchi approach, the present study proposes application of PCA to convert correlated responses into uncorrelated quality indices called individual principal components. The Composite Principle Component has been optimized by using Taguchi method. Analysis of variance (ANOVA) has been conducted for Composite Principle Component to find the optimal process parameters. Signal to Noise (S/N) Ratio has been found for PCA to find the optimal levels of the process parameters. Finally a conformation test has been made for three different materials and the results have been plotted. © 2017 Elsevier Ltd.

Chemical Speciation and Bioavailability | Year: 2014

Solute-solvent interactions of L-phenylalanine and maleic acid have been studied in various concentrations (0.5-2.5% w/v) of cetyltrimethylammonium bromide solution maintaining an ionic strength of 0.16 mol dm-3 at 303 K. The protonation constants have been calculated using the computer program MINIQUAD75 and the best fit models are arrived at based on statistical grounds employing crystallographic R factor, γ2, skewness and kurtosis. These protonation constants values have been found to shift in micellar media as compared to those in pure water. The differences in the values have been attributed to the solvent properties of the interfacial and bulk phases involving contribution from the micellar surface potential in the case of charged micelles. The trend of log values of step-wise protonation constants with mole fraction of the medium have been explained based on electrostatic and non-electrostatic forces operating on the protonation equilibria. Distributions of species, protonation equilibria and effect of influential parameters on the protonation constants have also been presented.

Currently huge data rates transmissions and their manipulations are completing by wireless distributed computing (WDC) network, for minimize the time. But by this network, we are unable to save the both power and bandwidth in much manner. These parameters will create critical issues, when wired or wireless media affects by noise, and interference conditions. In this paper, the main objectives are to produce good tradeoff between power consumption, bandwidth consumption and good tradeoff between distributed computing power ratio (DCPR), bandwidth consumption. I propose OFDM based WDC system, to achieve the very less interference and to satisfy the above specified objectives. This paper uses an optimization algorithm, called the particle swarm optimization (PSO). This algorithm gives global optimum solution. The performance of proposed system with an evolutionary algorithm is analyzed using MATLAB simulation. © 2015 IEEE.

In present days in an every communication, huge computational tasks are complete by wireless distributed computing (WDC) system. Extension of WDC system is OFDM based WDC system. OFDM based WDC system contains 3G or 4G technologies or standards(ex. LTE, WiMAX etc.).In this system, some of the major factors are power consumption and latency. These factors will produce critical issues, when wireless channel or wireless media effects by noise, scattering and interference conditions. In this paper, the main objectives are to produce good tradeoff between power consumption and latency and also produce good tradeoff between distributed computing power consumption (DCPR) and latency. I propose OFDMA based WDC system, to achieve the very less interference and to satisfy the above specified objectives. This paper uses an optimization algorithm, called the particle swarm optimization (PSO). This algorithm gives global optimum solution to above specified objectives.

In the present study, an attempt has been made to investigate the degree of pollution of ground water due to on site sanitation in Arilova slum area of Visakhapatnam of Andhra Pradesh. Surveys were conducted physically for selection of sampling sites in study area. Ground water samples exposed to leachate of on-site sanitation system collected seasonally for analysis. The water samples were analyzed for physico-chemical characteristics, such as pH, EC, nitrates, chloride. The data obtained were subjected to correlation analysis for statistical treatments. Water quality indices for ground water samples of study area were calculated to assess its potability and to summarize large amount of water quality data into simple terms. ©2015 - Kalpana Corporation.

The paper aims to analyze the heat transfer aspects of a two-layered fluid flow in a horizontal channel under the action of an applied magnetic and electric fields, when the whole system is rotated about an axis perpendicular to the flow. The flow is driven by a common constant pressure gradient in the channel bounded by two parallel porous insulating plates, one being stationary and the other one oscillatory. The fluids in the two regions are considered electrically conducting, and are assumed to be incompressible with variable properties, namely, different densities, viscosities, thermal and electrical conductivities. The transport properties of the two fluids are taken to be constant and the bounding plates are maintained at constant and equal temperature. The governing partial differential equations are then reduced to the ordinary linear differential equations by using a two-term series. The temperature distributions in both fluid regions of the channel are derived analytically. The results are presented graphically to discuss the effect on the heat transfer characteristics and their dependence on the governing parameters, i.e., the Hartmann number, Taylor number, porous parameter, and ratios of the viscosities, heights, electrical and thermal conductivities. It is observed that, as the Coriolis forces become stronger, i.e., as the Taylor number increases, the temperature decreases in the two fluid regions. It is also seen that an increase in porous parameter diminishes the temperature distribution in both the regions. © 2016 T. Linga Raju et al.

The search from time immemorial for stronger, lighter and more durable materials used in construction and tools continues to this day. This urge to discover, invent and synthesize new materials has resulted in innumerable kinds of alloys, plastics and composites owing to the very exacting demands from different industries like aerospace, automobile, chemical, marine and so on. Glass fibers reinforced in polymers have received considerable attention during the last century. Studies conducted during the last decade reveal that adding small amounts of foreign particles (like clay or silica) of nanosize significantly improves the engineering properties of the polymers. This study presents the effect of reinforcing epoxy polymer with Halloysite nanoclay on mechanical properties. In the present work the clay in terms 1, 2 and 3 percent by weight was surface treated with a suitable silane agent. The hybrid nanocomposite was prepared by the hand lay-up technique. Characterization of the nanoclay was done by X-ray diffraction and Scanning electron microscopy. ASTM standards have been employed for investigating hardness, dynamic mechanical properties, wear, damping and post underwater shock. All the tests were done for both silica and clay as reinforcement materials. Analysis and Results have been presented for impact of nanoclay reinforcement on all the parameters. Radial basis function network, a tool of ANN, is employed to predict the above outcomes. Mathematical regression models have been employed for theoretical prediction. Comparative study reveals that ANN Tool predictions have better agreement with measured values than the other model. Thus, it can be confidently concluded that ANN Tool can be used to predict the properties of hybrid nanocomposites before actual manufacture. This will result in considerable savings in terms of project time, effort and cost. © 2011 Published by Elsevier Ltd.

Chemical Speciation and Bioavailability | Year: 2013

Complexes of Pb(II), Cd(II) and Hg(II) with L-phenylalanine in the presence of non-ionic surfactants, at an ionic strength of 0.16 mol dm-3 and temperature 303 K are investigated pH-metrically. The existence of different binary complex species is established from modelling studies using the computer program MINIQUAD75. The increased stability of the complexes with increasing micellar content is explained by electrostatic forces. The influence of the micelles on the chemical speciation is discussed based on the mole fraction of the medium. Distribution diagrams of various species of the complexes in relation to pH are presented.
