1. SYNTHESIS OF MAGNETRON SPUTTERING-PHYSICAL VAPOUR DEPOSITION (MS-PVD) NANOMATERIALS

Authors -  S. Priyadharshini, Dr. K. Kavitha

Abstract : A Nano material is drawing in gigantic in ongoing specialists. It is incorporate into different research fields like physical science, scientific experts and material researchers. This exploration manages the union of nano materials of PVD and CVD. The PVD is broadly utilized procedure for slender movies covering. It is utilized in part of mechanical scale. In existing framework CVD builds the expense in the business and sets aside more effort for the planning of the covering. The primary downsides of CVD is doesn't give streamlining of the procedure and conveyed higher temperatures, initiating higher worries in the covering and substrate. So as to improve this proposed the Magnetron sputtering-Physical Vapor deposition (MS-PVD) system. It is improving vitality productivity level in modern setting. The experimental result correlation demonstrates the energy consumption level between the current and proposed framework. The nature of the covering is improved in this capacity and expanding vitality reserve funds.

2. SECURE DIGITAL SIGNATURE AUTHENTICATION SCHEME BASED ON EXTENDED CHEBYSHEV POLYNOMIAL OVER FINITE FIELDS

Authors -  Dr. R. Varalakshmi 

Abstract : Digital signature technology is a cryptographic mechanism that uses public key and private key which is very secure and sophisticated technology, and can also be encrypted and/or decrypted. This technology is mainly used for reducing the cost, to save valuable time and speedup of work. The usage of digital signature or the e-signature technology is increasing day by day in banking, insurance, corporate sector as well as in many fields of e-commerce, where the usage of electronic instruments / tools is essential. Therefore, this manuscript reviews different authors works involved in the process of digital signature. In this paper, a secure digital signature authentication scheme which extends Chebyshev polynomials from real field to finite field has been proposed, and it also suggests a trap-door one-way function for better performance.

3. DESIGN AND ANALYSIS OF COIL FRONT BUMPER IN AUTOMOBILE

Authors -  G.Venkatesan, B.Mohamed fazil1, S.Sravanan, G. Umar farook, K. Vinothkumar 

Abstract : Bumpers play an important role in preventing the impact energy from being transferred to the automobile and passengers. Saving the impact energy in the bumper to be released in the environment reduces the damages of the automobile and passengers. The goal of this project is to design a bumper with minimum weight by employing the glass material thermoplastic materials and coil spring & hydraulic cylinder absorb the shock. Bumper which either absorbs the impact energy with its deformation or transfers it parallel to the impact direction. To reach this aim, a mechanism is designed to convert about 80% of the kinetic energy to the spring and 20% of the hydraulic cylinder. In addition, since the residual kinetic energy will be damped with the infinitesimal elastic deformation of the bumper elements, the passengers will not sense any impact. Its solving and result’s analysis are done in CREO and ANSYS.
