Vibrations are observed in the ducts when the flow enters through regenerative air duct and gas turbine duct and flows through the diverging part of the boiler ducts. Due to this vibration, the boiler ducts have failed in their operation and had developed cracks on wall and finally damaged the whole system. CFD analysis is a new technique with the help of which we can solve the practical examples in a numerical manner and with the help of which a lot of time, money and materials can be saved. Here in this project CFD analysis can be used to predict the flow behavior inside the ducts by the help of which a prediction can be made so as to optimize the design of the waste heat boiler duct for minimum vibration. After the analysis it is found that CFD has helped in optimizing the model in a way that the introduction of the guiding plates has helped in reducing the disturbance of the flow which in turn will reduce the vibration in the model. Different cases are tried and results and discussion are presented in this report. Totally four cases are tried which consists of a base case without the guide plates and three cases with guide plates are tried. In the second case two guide plates are introduced at the RA duct and results are observed. Two guide plates didn’t gave proper flow and hence in third case 4 guide plates in the RA duct were introduced, this option gave better results in the RA duct but the flow in the RA duct the flow was not yet proper. Finally in the fourth case along with four guide plates in the RA duct, two guide plates in the RA duct was made and results were observed. It was found that the fourth model gave best results compared to all cases and hence is an optimized model.

Utility Mining is a rising research domain in the data mining and it discovers high utility itemsets in the data sets. The utility can be any user defined choice and to assign this utility value is based on the attributes of the dataset. For example in a transaction database it can be a price of purchased item, profit of item or quantity of items purchased. An itemset is known as high utility itemsets if its utility value is greater than minimum utility threshold. Utility mining is used in many applications like inventory control, retail store or super market management and marketing. Most of the existing algorithms generate candidate set to calculate high utility itemsets. Candidate item generation is more difficult and tedious task. In order to avoid this, high utility itemsets can be retrieved without candidate generation. An algorithm named as HUI Miner algorithm retrieves high utility items without candidate generation method. In this work, HUI Miner algorithm is enhanced with a utility function and set of effective pruning strategies. In this work utility threshold is calculated automatically by using utility function. Performance of enhanced HUI Miner algorithm is compared with the existing HUI miner algorithm. Different sizes of datasets are used for experimentation. The average size of the transaction is 10. Results proved that the enhanced algorithm reduces the upper bounds of high utility itemset. Hence it saves time and memory.

Through the fast growth of wireless technologies, Privacy of personal place information of a vehicle ad-hoc network (VANET) users is attractive a more and more important issue. Services provided by Location based services to VANETs users can breach by Sybil attacks. by malicious vehicles claim multiple identities at the same time. The avoidance of these attacks, which could arise in otherwise out of the Road Side Units (RSUs) reporting have a challenge to detect, as it should gather a cooperation between the ability to identify the real identity of the malicious vehicle, and avoidance of vehicle users starting being tracked by malicious entity. These papers propose a solution to stop and detect Sybil attacks in VANETs. The classification of attackers is based on two types of authentication techniques. The first uses discovery tags embedded in the vehicle to confirm them to the RSU and obtain short lifetime certificates. The second uses certificates to confirm vehicles to their neighbors. The vehicular network is divided into diverse zones brought under the control of dissimilar guarantee authorities (CAs), forcing a vehicle to change its diploma at what time touching from a zone to another. One important characteristic of the projected solution is that it prevents attackers from tracking the mobility of the vehicles. Avoid false negatives is also addressed using observers in vehicle nodes. A set of duplication scenarios also are performance to evaluate the presentation of the proposed solution. In last, these articles summarize the assessment between our proposed approach prevent the network from various hurtful property.
