Cloud computing has great potential of providing robust computational power to the society at reduced cost. It enables customer with limited computational resources to outsource their large computation workloads to the cloud. Outsourced computation contains sensitive information such as business, financial records, health records, etc., sensitive data have to be encrypted before outsourcing so as to provide data confidentiality. The study leads to the existence of another problem , when an unauthorized user search for data that are encrypted completely , the data that was retrieved to the user irrelevant, Which makes the cloud inefficient in providing data to the users. The proposed technique separates the sensitive data and non sensitive data, where sensitive data is alone encrypted by the session key, which enables better efficiency in providing non sensitive data to unauthorized users of cloud. The scheduler identifies the authenticated /unauthenticated and authorized unauthorized user based on their priority using ACL (Access control list) and delivers the session key. This technique reduces the computational time &resource and allows faster, reliable and efficient data access to all kinds of user.

The objective function of general K-Mean, this work associates a weight vector with each cluster to indicate which dimensions are relevant to the clusters. To prevent the value of the objective function from decreasing because of the elimination of dimensions, virtual dimensions are added to the objective function. The values of data points on virtual dimensions are set artificially to ensure that the objective function is minimized when the real subspace clusters or the clusters in original space are found. The outlier detection problem in some cases is similar to the classification problem. For example, the main concern of clustering-based outlier detection algorithms is to find clusters and outliers, which are often regarded as noise that should be removed in order to make more reliable clustering. This research work presents an algorithm that provides outlier detection and data clustering simultaneously. The algorithm improves the estimation of centroids of the generative distribution during the process of clustering and outlier discovery.Keywords

Medical study has revealed that people set a bigger possibility of countering free radicals and warding off illness by consumption of healthy foods and by increasing their resistant system. Due to the poor eating habits people suffer from many diseases. In the current scenario fast food become important food in daily routine because it is effortlessly available but taking fast food in routine may cause for disease like heart attack, diabetics etc. Healthier diets help us to maintain our health and keep us away from many diseases. For better recovery from diseases or surgery etc individual have special needs according to their medical profile, cultural backgrounds and nutrient requirements. Design and implementation of healthy diet recommendation system is based on web data mining which is t he application of data mining technique help us to determine pattern from web. In terms of accuracy and time performance analysis of recommendation system using two decision tree learning algorithm.

This paper evaluates Digital Accessible Knowledge on occurrence of Indian bird species. More than 2 million primary occurrence records from across India were obtained from the Global Biodiversity Information Facility and eBird. These were processed into maps of inventory completeness across the country both prior to 1980 and after 2000, in an attempt to develop evaluations of faunal change resulting from global climate change. We found good coverage of the country by well-inventoried areas after 2000, but almost no coverage prior to 1980. As such, in before-and-after comparisons documenting effects of global change on Indian birds, the ‘after’ is well documented, but the ‘before’ is lacking. This significant information gap points to the need for digital capture and open sharing of historical information regarding Indian bird species’ occurrences; this information will derive in large part from natural history museum specimens, particularly in India and Great Britain, and potentially from older observational data sources and the literature.Keywords

Objectives: The objective of this work is to investigate the flow over the truncated NACA2414 airfoil with slotted flap configuration. Investigation is carried using wind tunnel and commercial CFD tools with the consequences of the variation of speed, angle of attack of control surface and effective angle of attack. Methods/Statistical Analysis: Wind tunnel tests are performed on a reduced scale model (3:10) in wind tunnel at Manipal University. Experimentally determined static pressure distribution data at equal interval stations, placed over the wing are used to generate pressure data. The results obtained are used in turn as a benchmark to validate the CFD simulations. Findings: Findings clearly states that the blunt trailing edge has high drag coefficient. Although off set cavity and cavity has proven to be the ideal modification for trailing edge shape in a plane wing from the study. It can be concluded that the same is not true when such modifications are applied to slotted flap configuration. Application/Improvements: Further studies can be carried out with the alternative designs and a rigorous research can contribute in efficient designs in high lift devices.Full Text

Compression coating provides a unique platform for formulating modified release products in a way the dosage form can successfully be targeted to localize the release of the drug in any desired portion of the GIT without the additional step of film coating. The current work focuses on the development and optimization of modified release Verapamil Hydrochloride tablets using compression coating. The effect of various concentrations of different grades HPMC polymers, like, K4M, K15M and K100M on the release profile was studied in DOE environment. The results of the DOE provide an optimized range of the three polymers which could potentially give the targeted release profile for all drugs which have solubility profiles similar to Verapamil HCl. Three batches of optimized formulation were loaded on to accelerated stability studies at 40° C/75% RH in HDPE containers and the 3 months stability data indicates that there is no significant change in either the potency of the dosage form or its in vitro dissolution profile.Keywords

Solubility plays an important role in the formulation. When a drug is poorly soluble, their bioavailability will be affected. However, the solubility of the drug can be enhanced by using various methods like pharmaceutical approach, pharmacokinetic approach and biological approach. It can also be improved by formulating a lipid based drug delivery system. In the present study, nanoemulsion has been developed by using oil, surfactant and a co-surfactant in order to increase the solubility of poorly soluble BCS Class II and Class IV drugs. Nanoemulsions can be prepared by different techniques. In the current study, nanoemulsion has been formulated by using simple spontaneous emulsification approach. Artesunate was used as a choice of drug and capryol 90 was used as oil in the present study. Pseudo-ternary phase diagrams were used in order to determine the oil and Smix ratio. After the formulation, the product was subjected to various evaluation studies like droplet size, zeta potential, PDI and viscosity etc. Further, the in-vitro dissolution test was carried out for the formulated product, marketed formulation and the pure drug. And it was observed that the formulated product showed an improved drug release. In addition to these evaluation tests, accelerated stability studies according to the ICH guidelines were also carried in order to determine the shelf life as well as the effect of added ingredients on the stability of the product. The shelf life of the product was observed to be 2.38 years at room temperature.Keywords
