 Abstract

Sharing of data in cloud is widely used now a day. Cloud is used for storing data and applications on servers and accessing them through internet. Online data sharing for improved productivity and efficiency is one of the primary requirements today for any organization. In cloud data is stored on single machine and this stored data shared among multiple users by different machines. To store and also for sharing data securely cryptosystem is used. The data owner encrypt the data before it is upload to the cloud and then data decryption is done when user want to access it. In the existing system owner needs to generate individual key to the individual user. To overcome this problem in proposed system we generate a aggregate key and broadcast.

There are billions of web pages available on the Internet. Search Engines always have a challenge to find the best ranked list to the user's query from those huge numbers of pages. A lot of search results that corresponding to a user's query are not relevant to the user need. The incentive for this work originates from the need of retrieving useful web news pages from the Indian news websites corpus. News web pages contrast from other web pages; it is mainly vital to recognize web news accurately for precise classification. We will likely locate a simple yet efficient technique to mine news articles from web corpus. To accomplish this task, the automatic recognition method has been recommended for news web page classification that uses classification rules based on a combination of content, structure and uniform resource locator (URL) attributes. We gathered news web documents from 10 different news websites. We use Naive Bayes algorithm to distinguish news articles from non-news articles examples advertisements, not related links.

 Abstract

Construction of pavement involves huge outlay of investment. Addition of certain materials like coconut shells, seashells, saw dust etc may save considerable investment as well as gives reliable performance. The main objective is to encourage the use of seashells in pavement construction to reduce the marine pollution caused by it. Also, the disposal of seashells is difficult and tedious. This project describes the use of cockle seashells as partial replacement for coarse aggregate in bituminous pavement. It involves identification of proper mix by obtaining of proper mix by obtaining bitumen content (OBC) and appropriate seashell content by determining the Marshall Stability and Flow values. In this research work experiments have been conducted with collection of material required and data required for Marshall mix design are obtained by tests. The coarse aggregate is partially replaced with seashells in 10, 15, 20, 25, 30 and 35%. The OBC was obtained to be 5.5% by Marshall Stability test. Results show that replacement of appropriate cockle seashell content is able to produce bituminous pavement with satisfactory strength. Integeration of 25% cockle shell enhanced the strength of pavement making it to be the highest as compared to any other replacement level.

 Abstract

This paper boarder around design, fabrication and testing of a remote controlled airplane with high payload ratio. In the field of aviation, engineers play a vital role in solving complex problems like producing an airplane with high payload ratio, aerodynamic & performance efficiencies and structural safety. However, some of these problem statements are reduced in scale and given to engineering graduates for innovative results and applications. One such society which bridges this gap between industrial engineers and engineering graduates is the Society of Automotive Engineers (SAE). Two members of our project team have already registered for SAE Aero Design Competition 2018 which is going to held in California during April, 2018. The purpose of this project is the gradation of visionary design, manufacturing, system integration and experimentation of a remote controlled airplane with high payload ratio capable of lifting great loads while remaining as light as possible. An optimal design will be developed by maximizing the aerodynamic lift and reducing the aircraft weight without compromising the overall performance. However, the design must stay within the rules and restrictions of the SAE Aero Competition Guidelines

 Abstract

Using diesel engines mostly as main power source has gained the importance in the recent years. Technical specification of the diesel engine and its components has been the main focus of the researchers. The muffler is defined as a device for reducing the amount of noise emitted by an engine. The muffler is engineered as an acoustic sound proofing device designed to reduce the loudness of the sound pressure created by the engine by way of Acoustic quieting. Due to increased environmental concerns requiring less noise emissions combined with reduced emission of harmful gases, it is becoming very crucial to carefully design the exhaust system mufflers for road transport applications.In this Study comprehensively two different models of exhaust mufflers viz., reactive muffler and resonative mufflers are comprehensively analyzed to determine the best possible design for least pressure drop. Back pressure will be obtained based on the flow field analysis and compared with other muffler designs. Virtual simulation for back-pressure testing is performed by Computational Fluid Dynamic (CFD) analysis using Ansys CFD. Finite Element (FE) Model generation of the muffler structure is performed using Hyper Mesh as the preprocessor. The structural mesh is modeled using 2D shell elements, where in the internal tubes with fine perforated holes are considered. The CFD fluid meshing has been done with tetra elements using Ansys as the CFD preprocessor. As a result the back pressure generated across the muffler is determined by measuring and inputting the mass flow rate of the exhaust gases entering the muffler inlet pipe. Field view is used for post processing the CFD results and reviewing the airflow streamlines. The exhaust gas velocity and pressure plots are plotted across the internal tubes and perforated holes, and hence the back pressure is measured.

 Abstract

The overall objective of this study is to find an alternative solution for the large volume of sludge produced in the wastewater treatment plants . The generated quantities of sludge are expected to be 55.74 tons of solid per day by the year 2025. This large quantity of sludge is related to the scarcely of land area and high population density represented the sludge problem. Many researchers worldwide have been trying to explore new and suitable solutions to solve part of sludge problem. One track of these solutions is to use sewage sludge in construction field. The current study presents the usage of dry sewage sludge in the concrete mixtures and in manufacturing interlock brick samples. According to results findings, no significant strength loss was observed when low organic sludge was used in making concrete cube specimens. The strength loss was increased to 17% when 10% of high organic sludge pellets by cement weight was added to concrete mixture. The results showed that the dry sludge retarded the strength development and has more adverse effect on compressive strength when it has higher organic content and its particles became finer. The addition of dry sludge to interlock brick paste produced a reduction in compressive strength by only 12%. The presence of sludge in interlock samples decreased its density and increased its absorption coefficient. The NEN 7345 leaching test results indicated that the concrete matrix could be fixed more than 73% of total organic material in the worst case. Finally the study concluded that the dry sludge can be used in as an additive to concrete mixtures and to interlock brick paste as one of the available disposal options for sludge. The study recommended that more researches are needed to evaluate the durability of sludge concrete and the behavior of reinforced sludge concrete
