Processing map for hot working of Ti-IF steel has been developed in the temperature range of 750 to 1100 °C and strain rate of 0.01 to 100 s-1. This map in the austenite region exhibits a single domain with a peak efficiency of 45% occurring at 1025 °C and strain rate of 0.02 s-1. The domain extends over the temperature range of 1000 to 1100 °C and strain rate range of 0.01 to 1 s-1. The true s...

Substitution boxes with thorough cryptographic strengths are essential for the development of strong encryption systems. They are the only portions capable of inducing nonlinearity in symmetric encryption systems. Bijective substitution boxes having both high nonlinearities and high algebraic complexities are the most desirable to thwart linear, differential and algebraic attacks. In this paper...

This paper presents a simple yet e ective method for transforming Boolean functions that do not satisfy the strict avalanche criterion SAC into ones that satisfy the criterion Such a method has a wide range of applications in designing cryptographically strong functions including substitution boxes S boxes employed by common key block encryption algorithms The rst author was supported in part b...
