A Secure Decentralized Cloud Computing Environment over Peer to Peer
Tanupriya Choudhury,Vasudha Vashisht,Himanshu Srivastava
International Journal of Computer Science and Mobile Computing , 2013,
Abstract: Cloud computing platform is a set of scalable large-scale data server clusters, it providecomputing and storage services to customers. A cloud computing provider or cloud computing serviceprovider owns and operates live cloud computing systems to deliver service to third parties. The barrier toentry is also significantly higher with capital expenditure required and billing and management creates someoverhead. Nonetheless, significant operational efficiency and agility advantages can be realized, even bysmall organizations, and server consolidation and virtualization rollouts are already well underway. Cloudcomputing systems provide large-scale infrastructures for high-performance computing that are “elastic”since they are able to adapt to user and application needs. Cloud computing platform is a set of scalablelarge-scale data server clusters. The cloud storage is a relatively basic and widely applied service which canprovide users with stable, massive data storage space. Research shows that the architecture of current cloudcomputing system is central structured one; all the data nodes must be indexed by a master server which maybecome bottle neck of the system. In this project, the proposed new cloud storage decentralized architecture(no centralization is there, that’s why it’s designed in Peer to peer) and designed a prototype system. Thesystem based on the new architecture has better scalability and fault tolerance and proposed system designeda cloud based environment where request and response is taking place between client and chunk serversthrough Gateway. Anyone can take multiple chunk servers as well as multiple clients in the proposed system,this environment (client) can make request for deploying a web-service and also in this proposed system, it’simplement the cross-technology platform using the cloud based environment and at last proposed analgorithm with the help of “Advance Encryption Standard” which is going to provide security in the form ofencryption and decryption in the cloud based environment.
Sketch Recognition using Domain Classification
Vasudha Vashisht,Tanupriya Choudhury,T. V. Prasad
Computer Science , 2012,
Abstract: Conceptualizing away the sketch processing details in a user interface will enable general users and domain experts to create more complex sketches. There are many domains for which sketch recognition systems are being developed. But they entail image-processing skill if they are to handle the details of each domain, and also they are lengthy to build. The implemented system goal is to enable user interface designers and domain experts who may not have proficiency in sketch recognition to be able to construct these sketch systems. This sketch recognition system takes in rough sketches from user drawn with the help of mouse as its input. It then recognizes the sketch using segmentation and domain classification, the properties of the user drawn sketch and segments are searched heuristically in the domains and each figures of each domain, and finally it shows its domain, the figure name and properties. It also draws the sketch smoothly. The work is resulted through extensive research and study of many existing image processing and pattern matching algorithms.

AKSHATHA .P.S,VASUDHA VASHISHT,TANUPRIYA CHOUDHURY
International Journal of Innovative Research in Computer and Communication Engineering , 2013,
Abstract: Genetic algorithm is an optimization technique based on crossover and mutation operators using a survival of the fittest idea. They have been used successfully in a variety of different problems. Travelling salesman problem is one of the commonly studied optimization problem. In the travelling salesman problem we wish to find a tour of all nodes in a weighted graph so that the total weight is minimized. In this paper a single salesman travels to each of the cities but does not close the loop by returning to the city he started from and each city is visited by the salesman exactly once.

An Approach to Improve Task Scheduling in a Decentralized Cloud Computing Environment
Vandana Choudhary,Saurabh Kacker,Tanupriya Choudhury,Vasudha Vashisht
International Journal of Computer Technology and Applications , 2012,
Abstract: Cloud computing has emerged as a promising platform that grants users with direct yet shared access to computing resources and services without worrying about the internal complex infrastructure. As a cloud must provide services to many users at the same time and different users have different QoS requirements, the scheduling strategy should be developed for multiple workflows with different QoS requirements.Task scheduling problems are premier which relate to the efficiency of the whole cloud computing facilities. Task scheduling algorithm is an NP- completeness problem which play key role in cloud computing. The paper deals with Multiple QoS Constrained Scheduling Strategy of Multi-Workflows to address this problem. The proposed strategy can schedule multiple workflows which are started at any time and the QoS requirements are taken into account and are able to increase the scheduling success rate significantly in a decentralized environment.

International Journal of Pharmacology and Clinical Sciences , 2012,
Abstract: Background: Incorporation of Personal drug (P-drug) selection exercise into medical undergraduate curriculum was recommended to reduce irrational prescribing during future practice. At Melaka Manipal Medical College (MMMC), India, P-drug selection exercise was included in pharmacology curriculum in 2010 for 2nd year MBBS students. Objective: The study was conducted to develop a module to teach P-drug selection and to investigate students’ perceptions regarding P-drug selection teaching and assessment.Materials and method: Module was developed to teach P-drug selection for an acute attack of angina and dry cough based on a manual called as ‘Guide to Good Prescribing’ developed by the WHO Action Program on Essential Drugs. Power point slides, handouts with drug costs and current guidelines were used during teaching learning activities. Later students were assessed on P-drug selection by asking them to derive a P-drug for an acute attack of angina. Students’ answers were assessed using a checklist. Later students’ perceptions regarding P-drug selection teaching and assessment were collected using a questionnaire. Data was analyzed using SPSS 16. Students’ responses were expressed as median and inter quartile range. Responses to open ended questions were tabulated in the decreasing order of frequency of appearance. % of students who scored ≥4 (= pass) markswas noted.Result: 90% (95/106) of students responded in the questionnaire. Most of the items in the questionnaire related to teaching and assessment had a median score of ≥3. 94.3% of students had scored ≥4 in P-drug selection exercise. 84% of students felt that P-drug selection teaching helped them to understand pharmacology better. They wanted more such exercises and more explanation to understand P-drug concept better. Conclusion: Study led to development of P-drug selection teaching module acceptable to students. Furthermore it also provided scope for the refinement of newly developed module based on students’ perceptions.
International Journal of Pharmacology and Clinical Sciences: a knowledge base for scientific enquiry and better patient care

International Journal of Pharmacology and Clinical Sciences , 2012,
Abstract: The current health care system of the world is dependent on the modern medicine which focusses on curative rather than preventive aspects of medicine. The modern medicine has increased the life expectancy and quality of human life by delivering remedial measures for several diseases. This was possible because of advances in research and availability of evidences to practice medicine. However, in lowincome and middle-income countries, drugs account for 20—60% of health-care costs. [1] The large proportion of these costs is paid out-of-pocket by patients which could be due to inadequate or no coverage by health insurance. To make the condition worse, a third of the world's population lack access to essential medicines.[2] Cost of drugs is one of the factors contributing to the problem of access to medicines. It is estimated that, in India, out-of-pocket health expenditure traps 2.2% of the population below the poverty line each year.[3] In addition, the Indian health system has to face many other challenges like inadequately controlled infections, emerging epidemic of chronic diseases associated with western lifestyle in the near future. Hence, reforming the health system focussing on both preventive and curative aspects of health care services to make it rationale, affordable and accessible is the need of the hour.
