A new trend of implementing Bring Your Own Device (BYOD) as an IT policy is being adopted by companies worldwide. It permits employees to bring their own portable devices like tablets, smartphones, etc to workplace and use them to access confidential corporate information while being both inside and outside their place of work. BYOD clearly raises serious security concerns since the device in question is not under the control of the enterprise and is vulnerable to a wide range of security threats. One of the major concerns in implementing a BYOD policy is data security and privacy. By allowing employees to access privileged corporate information on their personal devices, pertinent corporate data may be compromised. In this article, we address this problem and propose a solution that enhances the security in the BYOD scenario without compromising the usability and flexibility of the system. We suggest a sandbox which takes care of common connection, encryption and other security credentials for BYOD applications and helps monitor application usage on device for administrators.

The present work deals with minimization of sand casting defects in a foundry industry. DMAIC approach is justified when root cause of defect is not traceable. At present, global and competitive environment, foundary industries need to perform efficiently with minimum number of rejection in their manufacturing products. For better improvement in the casting quality, first of all finding the root causes of occurrence of defects blow hole in the casting process and taking necessary step to reduces defects and hence rejection in casting. Six sigma is more than a quantitative statistical measure of processes; it embraces every aspect of work, using a disciplined, fact based approach of problem-solving. Many time defects occur due to variation in the process parameter which are very difficult to detect. In the present work the metal casting process is analysis and minimised by using DMAIC (Define, Measure, Analysis, Improve, and Control) approach. Through a case study in a medium scale faundary, the present work formulate a comprehensive strategy of six sigma in indianfoundary. This study has significantly increase the efficiency of foundry industry and reduce scrap and waste in sand casting process which improve the production efficiency.A number of experiments are carried out to validate the results which indicate that the cost of experimentation will be less, in comparison to the gain or profit of the company. The results achieved shows that the rejection due to blow hole defects has been reduced from 5.83% to 2.04% which saved the cost of Rs 23828/- monthly (for continuous four months), in a turnover of 60 lakhs.

This project is based on ticketing and identification of the passenger in the public transport. In the big city like Mumbai, Kolkata we have a severe malfunction of public transport and various security problems. Firstly, there is a lot of confusion between the passengers regarding fares which lead to corruption, Secondly due to mismanagement of public transport the passengers faces the problem of traffic, thirdly we have severe security problems in public transport due anti-social elements. This project suggest a user friendly automated ticketing system which will automatically deduct the passenger’s fare according to the distance travelled as well as detect the passenger’s identification. This could be only possible by use of NFC e-tickets. This project basically deals with the verification and ticketing of the passengers sitting in the bus.

Nowadays action recognition has many applications such as robotics, human computer interface etc. This project proposes a method for action recognition that uses a number of correlated poses. Here normal video is converting to silhouette video and then each silhouette video is converting to a set of images frames for feature extraction. The silhouettes are used as input features for the BoCP ( Bag of Correlated Poses) model. BoCP are using for encoding the local features of action. After the descriptor extraction C-means clustering algorithm is using to generating the codebook. Clustering is the process of dividing the dataset into subsets, so that the data in each subset shares some common values according to some defined distance measure. To reduce the high dimensionality of computed feature Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) are using. Experimental results prove the viability of the complementary properties of two descriptors and the proposed approach outperforms the state of the art methods on the IXMAS action recognition dataset.

WELL method mainly describes that the 7.1 fold faster technique is inbuilt to increase the efficiency and reduce the area. The proposed architecture also implemented on targeting different device for the comparison of other types of PRNG. Interleaver sequence technique is used. A large number of research is made on PRNG compared with the MT algorithm specified for less than 423 MHz of frequency range. Now a days the recent communication technique is made for the WELL method along with the PRNG to achieve the high frequency range than the 423MHz. A resource – efficient hardware architecture for WELL with a throughput of one sample per cycle. The Well Equidistributed Long-period Linear (WELL) algorithm is proven to have better characteristics than the Mersenne Twister (MT), one of the most widely used long-period pseudo-random number generators (PRNGs). In this paper, we propose a hardware architecture for efficient implementation of WELL. Our design achieves a throughput of 1 sample-per-cycle and runs as fast as 423MHz on a Xilinx XC6VLX240T FPGA Furthermore, we design a software/hardware framework that is capable of dividing the WELL stream into an arbitrary number of independent parallel sub-streams. With support from software, this framework can obtain speedup roughly proportional to the number of parallel cores. We also apply our framework to a Monte-Carlo simulation for estimating p. Experimental results verify the correctness of our framework as well as the better characteristics of the WELL algorithm.

We have reached an era where desired web services are available over the networks by click of a button. In such a scenario, remote user authentication plays the most important role in identifying the legitimate users of a web service on the Internet. Researchers have proposed a number of password based authentication schemes which rely on single server for authentication. But, with tremendous advancements in technology, it is possible to engage multiple servers in authenticating their clients in order to achieve better security. In this paper, we propose an efficient password based authentication protocol for multiserver architecture. The protocol provides mutual authentication using user system and is based on Elliptic Curve Cryptography, therefore offers best security at a low cost. In 2011, Sood et al. proposed a multi-server architecture protocol using user systems. In this paper, we improve Sood et al. scheme by increasing its security and reducing the computation cost. The protocol is based on the concept of dynamic identity that uses a nonce based system and has no time synchronization problem.

Mobility is the most important feature of a wireless cellular communication system. This continuous service is achieved by Handoff (or Handover) from one cell to another cell. Handoff (also called Handover) is the mechanism that transfers an ongoing call from one cell to another cell as a user moves through the coverage area of a wireless cellular system. The main objective of handover is to maintain the ongoing calls. Many times it is initiated by crossing a cell boundary or by deterioration in quality of the signal in the current channel. Handovers are used to prevent an ongoing call to be disconnected. If handovers are not used then whenever a user leaves the area of a particular cell then its ongoing call is immediately disconnected. The handover process requires a number of parameters e.g. which handover scheme we are using, how many channels are free for call. In the handover process the QoS should be kept up to the standard. Handoff schemes which are poorly designed tend to generate very heavy signaling traffic and, therefore, there is a dramatic decrease in the quality of service (Qos). The reason for the critical handoffs in cellular communication systems is that in neighboring cells always a disjoint subset of frequency bands is used, so negotiations must take place between the current serving base station (BS), the mobile station (MS) and the next potential BS.

A ‘hybrid electric two wheeler' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions. In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill climbing the electric motor provides additional power to assist the engine. This allows a smaller, more efficient engine to be used. Besides it also utilizes the concept of regenerative braking for optimized utilization of energy.

In today’s scenario, there is more and more interest being taken to produce current in alternate forms rather than getting directly and environment friendly technologies may be incorporated. One of the best methodologies to generate electricity by using human walking. When humans walk, they produce a lot of energy which is of no use. This kinetic mechanical energy derived from human walking can be used to generate energy to run home appliances like charging a mobilephone. This system involves designing a charging system which is powered via a piezoelectric and that is capable of charging more than one batteries at the same time. In this proposed system, The surface under the foot path collect energy from the vibrations, The piezoelectric charging panels channel energy batteries which can be used further. Our system measures the power level produced and monitors it frequently. Here alternative sources like noise can also be added to boost up the voltage ,and that voltage also can be saved in the battery for further use .This method can be employed in lots of day today places like railway station, shopping complex where lots of people crowd together ,This method has only investment and very reliable too.
