1 Secured Cloud Storage Using Divide And Conquire Method
C.S.Subramaniyam

Abstract-cloud computing is more used and become more popular nowadays. Cloud provide many services like storage, infrastructure etc. As cloud storage on internet is public in nature, there is a risk of our data being hacked by any hacker. To ensure the security of our data there are many cryptography algorithm. Using a single algorithm is not efficient nowadays. If we use more than one algorithm serially it will be more time consuming so, we propose a new methodology by using hybrid cryptography algorithm.

2 Efficient data allocation based on deadline guaranteed Service scheme
SK.Manigandan, K.Sukanya

Abstract-Multi-tenant cloud storage is used for storage purpose in which we used to buy space from the cloud server. Basically if we need space we use to send request to the admin and then the request is forwarded to the Cloud Service Provider (CSP). The cloud storage providers will provide deadline guaranteed services regarding Service Level Agreements (SLA) for online providers. Most of the previous system uses the workflow scheduling or resource reservation in network but totally avoids the overloading issues. In this paper, we propose a new SLA for each tenant that serve within a particular deadline. We initially identify several objectives such as traffic & latency minimization and resource utilization maximization. A Parallel Deadline Guaranteed (PDG) scheme is used for scheduling data reallocation purpose through data replication. We clustered the servers according to their file, which in the sense video, image and documents. We introduce several algorithms relating to the PDG, such as (1) prioritized data reallocation and (2) adaptive request retransmission. These both algorithm performances will deals with the request arrival and requirement variation. We also introduced a virtual space when there is an overloading of data’s or information in the cloud server. If there is an overloading of data then it must be reallocated to the virtual space respective to the file, because we have already clustered the server into three category regarding their file namely, image, video or document.

3 An Experimental Study on Effect of Various Accelerators on Strength Parameters of Concrete
Akhilesh Joshi, Rahul Sen, Tapas Singh, Avinash Kumar Singh

Abstract-This paper presents an experimental study conducted on concrete cubes and beams to see the effect of accelerators on compressive and flexural strength of concrete at standard days of curing. In this experimental study Ordinary Portland Cement (OPC) was used to produce concrete mixtures M20. Concrete mixtures for study were designed as per the new guidelines of IS 10262:2009. Three accelerators Potassium Carbonate, Sodium nitrite and calcium nitrite were used. Both compressive strength and flexural strength of standard specimens with accelerators have been recorded at one, three, seven, fourteen and twenty-eight days of curing with water and compared with strengths of controlled specimens at their corresponding ages. The test results revealed that the maximum percentage gain was observed for Calcium nitrite accelerator out of three accelerators at 1, 3, 7, 14 and 28 days compressive and flexural strength for M20 grade of concrete. Also there is a very little change in 28 days compressive strength and flexural strength with all accelerators for M20 grade of concrete.
