Cloud computing is a developing technology which gets more attention from both the industries and academia. The cloud storage is one of the main benefit in cloud computing, which is particularly attractive for the users who needs unpredictable storage for their enterprises and so on. Minimum storage and processing cost is an obligatory requirement of all organization and industries, while analysis of data and information is mandatory in all organization. Although there is a reduction in cloud storage cost, customers has to face more technical and security problems such as data integrity, confidentiality and availability. If there is no confidentiality, then, there is no guarantee for the data on cloud. Many researches have been proposed number of techniques for data security in the cloud. However, there are still many issues in cloud data storage. The optimum solution to ensure the confidentiality in cloud storage is to encrypt the data whereas encryption alone fails to give high security to the data in the cloud storage. To give maximum protection to cloud storage, this paper proposes a unified combined model of both encryption and obfuscation. Encryption is the process of converting original text and Obfuscation is a process of encrypting numerical type of data, the researchers proved that by combining these two data protection techniques, the data will be more protective on cloud storage.

One of the main objectives of factor analysis is to reduce the number of parameters. The number of parameters in the original model is equal to the number of unique elements in the covariance matrix. The study compared ordinary least square and maximum likelihood method of extraction of factor analysis under two approaches such that the variables employed were assumed to be independent of error i.e endogeneity assumption in the first approach while the endogeneity assumption is violated by omitting the important variable HLT in the second approach. The result showed that the extracted factors under the violation of endogeneity has similar factors loading pattern which accounted for a great deal of variance and the factors do a good job of representing the original data and the Bayesian information criterion also showed that the maximum likelihood method of extraction slightly outperforms ordinary least square.

Application of activated carbons developed from cashew nut and Tamarind seed carbon from the agricultural waste product has been investigated for the removal of reactive magenta, reactive red, acid orange and crystal violet dyes from aqueous solution and waste water. Batch adsorption experiments are carried out for the removal of dyes from aqueous solution by using cashew nut and Tamarind seed carbon. The important parameters are studied like initial concentrations of dyes, contact time and dose of carbon for the removal of dyes. The data are fitted into Langmuir and Freundlich adsorption isotherm models and their constants are determined. For the kinetic study of the adsorption process under consideration, the following kinetic equations proposed by Natarajan and Khalaf, Lagergren, Bhattacharya and Venkobachar were employed. The intra- particle diffusion processes in often the rate limiting step in much obey first order nature of the adsorption process. The characterization of the physio chemically modified carbons are carried out by SEM, XRD analysis, UV-Visible and FT-IR analysis of before and after adsorption of dyes on the carbon surface area morphology studied.

The radiation effects on unsteady transient free convection flow of a viscous incompressible gray, absorbing-emitting but non-scattering, optically-thick fluid occupying a semi-infinite porous regime adjacent to an infinite moving hot vertical plate with constant velocity taking viscous dissipation onto account has been carried out. Thermal radiation effects are simulated via a radiation-conduction parameter (),rK based on the Rossseland diffusion approximation. We employ a Darcian viscous flow model for the porous medium. The momentum and thermal boundary layer equations are non-dimensionalzed using appropriate transformations and then solved subject to physically realistic boundary conditions using the Ritz finite element method. The computed numerical results for velocity(),u temperature(),θ shear stress function()τ and wall temperature gradient function()Nu are presented through the graphs and tables for air (0.71)rP= and water (7.00).rP= It has been found that increasing thermal radiation parameter ()rKcauses a considerable increase in the flow velocity .u Temperature θ is significantly increased within the boundary layer with a rise in.rK The velocity is found to decrease with an increase in inverse permeability parameter ()pK and increases with increase in the Grashof number ()rG and Eckert number ().

Now a day, there is a growth of digital images and video archives. Some of these are very important from user point of view. The collection of these digital images may be for personal use and may be for public use. For searching images in the database, there is the need of secure, fast and efficient techniques. Tag-based image search is an effective technique to find images in the databases and in the social websites. In this paper a reranking system for image retrieval with the consideration of images relevance and diversity is proposed. Reranking of the images have done according to their visual features and semantic features. Visual features are used for detecting duplicate images in proposed method. Each user maintains several images. First sort these images by same group user ranking system. Users that have higher contribution to the given query rank higher. Then an implementation to all-user reranking on the ranked users image set and only the most relevant image from users image set is selected. These selected images compose the final retrieval results. We build an inverted structure for the image dataset to speed up the searching process.

First-principles calculations based on Density Functional Theory have been done on the technologically important Proline derivative (3,4-Dihydroxy-5-(hydroxymethyl)(proline) [????6????11????????5]. The triclinic structure of the material has been simulated and the structural parameters are found to be a=4.309Å, b=6.004Å, c=6.967Å, ????=103.47????, ????=103.17????, ????=99.80????. After fluorination the structural parameters are found to be a=4.301Å, b=6.214Å, c=7.113Å, ????=105.10????, ????=104????, ????=97.68????. Electron Density of States (EDOS) has been computed in the material using the Electronic structure calculation code of Quantum-Espresso which gives a Band gap of 4.47 eV. After fluorination the Band gap is found to be 3.34 eV. The value of dielectric constant in the material comes out to be 2.32, 2.70 and 2.61 along x, y and z axes respectively and the average value comes out to be 2.54. After fluorination the dielectric constant of the compound comes out to be be 2.38, 2.56 and 2.56 along x,y and z axes respectively the average value comes to be 2.50. The computed phonon modes range from 101????????−1 to 3157????????−1. After fluorination the phonon modes range from 306????????−1 to 3563????????−1.

Alzheimer Disease (AD) is one of the common forms of dementia which is an irreversible neurodegenerative progressive disorder of the brain which affects the elderly population above the age of 65. Alzheimer is a brain disease that causes problems with memory, thinking and behaviour. It is severe enough to interfere with daily activities. Alzheimer symptoms are characterized by memory loss that affects day-to-day function, difficulty performing familiar tasks, problems with language, disorientation of time and place, poor or decreased judgment, problems with abstract thinking, misplacing things, changes in mood and behaviour, changes in personality and loss of initiative. There are different types of tests associated with AD such as neuropsychological tests, laboratory tests and various imaging modalities for the early diagnosis of AD. Although these tests are available, they are inadequate for the definite diagnosis of the disease. In this paper we focus on the databases related to AD such as ADNI (Alzheimer’s Disease Neuroimaging Initiative), TREAD (Trajectory-Related Early Alzheimer’s Database), CAMD (Coalition Against Major Diseases), and NAAC( National Alzheimer’s Coordinating Center). The use of these internet sources, soft computing techniques and image analysis from the different imaging modalities in an efficient way for making a definite diagnosis and early confirmation of AD. Our aim is to predict the early diagnosis in a reliable manner such that to combine the values of different tests with the help of soft computing techniques to develop software tool for a definite diagnosis.

Gait recognition is the process of identifying an individual by the manner in which they walk. Using gait as a biometric is a relatively new area of study, within the realms of computer vision. It has been receiving growing interest within the computer vision community and a number of gait metrics have been developed. The term gait recognition to signify the identification of an individual from a video sequence of the subject walking. This does not mean that gait is limited to walking, it can also be applied to running or any means of movement on foot. While gait has several attractive properties as a biometric there are several confounding factors such as variations due to footwear, terrain, fatigue, injury, and passage of time. Examples of motion that are gaits include walking, running, jogging, and climbing stairs. Sitting down, picking up an object, and throwing and object are all coordinated motions, but they are not cyclic. Jumping jacks are coordinated and cyclic, but do not result in locomotion. The use of gait as a biometric for human identification is still young when compared to methods that use voice, finger prints, or faces.

All business web crawlers give back similar results for a similar inquiry, paying little respect to the client’s genuine intrigue. Since inquiries submitted to web indexes have a tendency to be short and uncertain, they are not liable to have the capacity to express the client’s exact needs. They make discovering data on the web fast and simple. A noteworthy inadequacy of non-specific web indexes is that they take after the ”one size fits all” model and are not versatile to individual clients. Distinctive clients have diverse foundations and interests. In any case, successful personalization can’t be accomplished without precise client profiles. Various grouping calculations have been utilized to arrange client related data to make precise client profiles. In this paper, it presents develops client conduct profile naturally as a methods for the execution internet searcher that is gone for building on the web, versatile shrewd frameworks that have both their structure and usefulness advancing in time.
