the main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. the calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. in this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. finally, the analysis an...

analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. according to this, an impressive analytical method which is called modified iteration perturbation method (mipm) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. this new method is combined by the mickens and iteration methods. moreover, this method don...

This paper studies the effect of high performance pipelined GF(2 256 ) bit-serial multiplier on elliptic curve point operations. A 3-stage pipelined version of the Massy-Omura GF(2 m ) normal basis multiplier for 160 ≤ m ≤ 256 was studied in terms of area overhead and throughput improvement. Simple gate area and delay models were used to estimate the throughput of the pipelined and the non-pipe...

in this paper, we give some characterizations for legendre spherical, legendre normal and legendre rectifying curves in the 3-dimensional sasakian space. furthermore, we show that legendre spherical curves are also legendre normal curves. in particular, we prove that the inverse of curvature of a legendre rectifying curve is a non-constant linear function of the arclength parameter.

Abstract Elliptic Curve Encryption (ECC) has been widely used in the field of digital signatures communication security. ECC standards and diversification application scenarios put forward higher requirements for flexibility processors. Therefore, it is necessary to design a flexible reconfigurable processor adapt changing standards. The cryptographic chip designed this paper supports choice pr...
