In the present world of wireless technology, many algorithms like RC5, DES and AES are available for sending and receiving the information. But all these algorithms are not sufficient to provide the security and data confidentiality. The objective of this paper is to overcome the drawbacks of various other algorithms such as RC5, DES and AES using single key & to enhance the security of the data transfer over the network. To accomplish this we have arrived at the idea of data encryption using multiple keys.A new FPGA based advanced encryption Standard (AES) -192 with multiple keys encryption is proposed in this paper. In our present work, we have proposed new method which increases the security, Data confidentiality and efficiency of encryption when compared to other algorithms. The cryptographic algorithm, which is in use, is static i.e. only one of the standard algorithms is used at a time and uses only one key throughout the conversation. If same key is continuously used, the crypto analyzers may crack the code or find out the encryption method and may intrude or spy or hack the confidential data. This necessitates a robust encryption technique. This work highlights one of the novel approaches of an implementation of a highly secured cryptic algorithm in FPGA, which makes near impossible for data theft. We have used multiple keys for encryption and the data can be protected effectively. Source

In the present work, an attempt has been made to investigate the strength of bolted fasteners and hybrid fasteners under tensile loading for unfilled, TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). Bolt configurations were chosen as 2, 3 and 4, in order to analyze the effect of number of bolts on the strength aspect. For filled GFRP composites, the volume fractions in the matrix were chosen as 1%, 2% and 3%. The result obtained shows that, the static tensile strength of the GFRP composites increases with increase in number of bolts. Specimens with 4 bolt configurations have shown significantly more absorption of load before failure of the joint. Hybrid fasteners are more sustainable to failure than bolted fasteners. Also it is noticed that, the strength of the composites increases with raise in TiO2 and ZnS fillers content up to 2vol.%. In comparison with TiO2 and ZnS filled composites, it was found that ZnS filled composites bears more load. © 2013 Elsevier Ltd. Source

Mucuna pruriens belongs to the family Papillonaceae. The seeds and leaves of these plants contain a large amount of L-DOPA. L-DOPA (L-3,4-dihydroxyphenylalanine) is one of the most widely used drugs in the treatment of Parkinson disease. Development of an efficient gene transfer method is an absolute requirement for genetically improving Mucuna pruriens and creating plants with more desirable traits. A simple protocol was developed for the Agrobacterium-mediated stable genetic transformation of M. pruriens. Agrobacterium tumefaciens strain EHA 101, containing the vector pCAMBIA1305 and the hptII and GUS plus genes, was used for the gene transfer experiments. Putative transgenic shoots were obtained on medium supplemented with kanamycin (50 mg L-1) and cefotaxime (400 mg L-1). GUS histochemical analysis of the putative transgenic tissues further confirmed the transformation event. Genomic polymerase chain reaction (PCR) analysis was performed to verify the presence of transgenes and their stable integration. Transformation mediated by Agrobacterium in M. pruriens is reported for the first time. © TÜBITAK. Source

The main affecting parameter for Delamination of the composites and in turn the failure of composites is the Thrust force. In the present work an attempt has been made in order to investigate the Thrust force generated during drilling of the TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and3%. A plan of experiments, based on the techniques of Taguchi, was performed to acquire data in a controlled way. An L27 orthogonal array and analysis of variance (ANOVA) were employed to investigate the influence of process parameters on the drilling of these composites. Drilling has been conducted on a radial drilling machine. Speed of drilling (S), volume fractions (VF) and drill tool diameter (D) were considered as the varying parameters with three levels. Thrust force has been considered as the output parameter and is been measured in each combination of parameters chosen. Results reveal that, the addition of filler will increase the thrust force developed during drilling. As per ANOVA values, drill tool diameter contributes more towards generation of thrust, followed by speed of drilling. Main Effect plots shows that, contribution of speed towards thrust generation is only upto a certain level of increase in speed. Copyright © 2014, IGI Global. Source

In the present work an attempt has been made to investigate the bearing strength of the TiO2 and ZnS filled glass fabric reinforced polymer matrix composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and 3%. Single-hole-pin-loaded specimens of each composite material were tested in tension. The result showed that the bearing strength of the glass fabric reinforced polymer matrix composites joints is associated with the filler content and the geometrical parameters. The increase of the filler content in the matrix has increased the bearing strength of the composites. The height bearing strength was obtained in case of composites with 2 volume% of filler content, and it was found that ZnS filled composites bears more load than the TiO2 filled composites. © The Author(s) 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
