Cloud computing has been imagined as the cutting edge building design of big business IT. Lamentably, the integrity of cloud information is liable to issues because of the presence of programming disappointments and human lapses. The data should be kept confidential and should be kept private to the public verifier. We extend this architecture by introducing consistency as well as security. We introduce a hybrid encryption algorithm to effectively encrypt the data files of users in cloud server. The hybrid algorithm supports the data confidentiality, privacy preserving of data. Together with this, system supports data sharing by maintaining consistency.

User’s locations and there interested are different. Collecting large amount of data to the user is very difficult. Sometime information is very sensitive; handling the information is very difficult task. Information storage also very big issue.so data owner does not make data accessible in all customers. It’s allowed only paying customers. User send their current location points and want to know about nearest POIs in NN but data Owner does not have that much storage capacity so we are using cloud service. Cloud provides power full storage at low cost but Cloud is not fully trusted. So we are using processing of NN queries in an untrusted outsourced environment, whereas at an equivalent time protective the POI and querying users’ location positions. Our techniques based on mutable order preserving encoding (mOPE). It is a secure order-preserving encryption. We provide performance of the optimizations process is increase and decrease the computational cost.

Pages: 190 - 195
Wireless sensor network is composed of sensor nodes and multiple sink in which each sensor node is capable of detecting events. The main problem arise in the network is it remains unattended for long duration because these networks are placed in remote areas. So to extend the network lifetime of a network, node energy must be efficiently used. So in order to efficiently use energy of the network sleep wake scheduling method is used. Asynchronous sleep wake scheduling arrange sensor node to sleep mode when transmission or reception is not required. It allows sensor nodes wake up independently with the given rate. But it has got a disadvantage that additional delay may occur in each node along the path to sink node. So to minimize this problem opportunistic routing is used. In this method it selects some nodes as forwarding nodes and through these nodes it sends the packet. In the above methods it has got some limitations that sink node has to wait for long time to receive the transmitted signal. So clustering method is used. clustering enables efficient resource allocation and thus help in better designing of power control and other advantage is due to the fact that any changes of nodes behavior within a cluster affect only that cluster but not the entire network, which will therefore be robust to these changes. The main objective of this project is to reduce the energy consumption and to increase the packet delivery ratio (ie, ratio between received packet by destination and generated packet by source)

A navigation system which utilizes the online information gathered from the VANET to guide the drivers to desired destinations in a continuous and real time manner. Vanet based secure and privacy preserving navigation scheme (VSPN) helps to find a better route and also it satisfies all privacy and security requirements. For improving the energy efficiency of individual nodes in VSPN, Long Term Evolution (LTE) technique is introduced. LTE will help to achieve better data rates and content distribution delay can be minimized. This paper aims at describing the analysis and evaluation of VSPN navigation schemes and its enhancement using LTE.

Pages: 202 - 206
Cyber Physical Systems are primarily focused to interact with other systems across the data collection. Information collection depends on the field of knowledge discovery. This contains information either from field based or collaborative filtering. In a domain recommendation model, filtering data based on the rating pattern across the domains. The basic functionality of the cross domain recommendation model is to seek and retrieve the information with reduced the repeated records. A domain recommendation model, which are identifying the common routing pattern across specific domains and determining the specific domain rating patterns in each domain containing similar behavior and relation which exists among the fields. For the clustering information, system utilizing a different data set with an additional amount of accumulating data. These data sets are compared and filtered with items and are clustered with domains. The clustering process reduces the uncompleted data sets and offers more meaningful data. Domain recommendation model mainly integrating the knowledge discovery and information transport as part of the information transfer organization. The major type of systems is offered retrievals of items through the single field. The cross domain recommendation provides data by integrating multiple areas with identical details.

Pages: 224 - 228
In recent years, many numerical and experimental studies on heat transfer have been discussed with different configurations. Here CDD (convergent divergent spring tabulators) CDDSTs were placed in the inner tube of double pipe heat exchanger and effect on heat enhancement and friction factor was experimentally investigated. CDDSTs at various pitches i.e (p=0,p=15,p=16) were used for the different ranges of Reynolds number. For cold water its ranges between 9000to17000 and for hot water 18000 to 24000. Results from CDDSTs were compared with plane tube and results showed that Nusslet number increased while friction factor decreased with increased in Reynolds number. Friction factor was increased by 287% while Nusslet no increased by 28%. . However thermal performance factor was maximum for CDDSTs (p = 15) with value 0.319.

Pages: 229 - 233
Web is a huge repository of data. Inorder to automatically extract relevant data from web documents, web data extractors are used. The proposed technique works on two web documents that are generated by the same server-side template and learns a regular expression which represents the template of the web document. The regular expression generated can be later used to extract data from other similar documents. The proposed technique builds on the hypothesis that template introduces some shared pattern that do not provide any relevant data. In the regular expression the capturing groups represent the data. The semantic label for each capturing group is provided based on the POS (Part Of Speech) tagging. This technique could even work with the malformed documents. Hence the input errors do not have negative impact on the effectiveness.

Pages: 234 - 237
In many real time applications such as sensors monitoring systems, location based systems etc data uncertainty is inherent. The uncertainty may occur as a result of evaluation errors. This uncertainty becomes a major issue while performing mining operations in the databases. Traditional mining methods are less efficient when dealing with uncertain databases. While considering uncertain databases one of the major issues is to mine frequent item sets from database. Here some algorithms which are used to perform frequent pattern mining in uncertain databases are provided. These algorithms discussed here are the extension of the frequent pattern mining algorithms which are used in deterministic databases where the values are precise. These algorithms are modified in such a way to handle uncertainty in the database. Among the various algorithms the U-prefix span algorithm an extension of prefix span algorithm gives better performance. Clustering is used in this algorithm to further increase the efficiency.

Along a major highway, luminaries pole structures may be seen every 101 of a mile. From documented cases, it appears that these structures started to experience fatigue problems in the last three decades. The general public might not be aware of the problem, because if such a failure occurs, the structure is replaced. Those working in the fatigue area realize that this issue is a serious matter. Clearly, the damage is costly, costing up to thousands of dollars per occurrence. For this purpose, a high mast lighting poles are fabricated using steel due to its high strength, ductility property and wear resistance. The high mast structure (HMS) has the characters of light weight and high cost efficiency. It possess large ratio of height (H) to least horizontal dimension (D) that makes it more slender and wind-sensitive than any other structures[17]. Therefore, the purpose of this research is to design optimal high mast poles taking into account its specification, environmental conditions for placement economy.
