An Efficient Step Size For BFGS
ABSTRACT:
In this paper we introduced what we are calling a combination of step size of Broyden-Fletcher-Goldfarb-Shanno (CSS-BFGS) to solve unconstrained optimization problem. Analytically, we have proved that the algorithm is superlinearly convergence. The numerical result of CSS-BFGS was shown at the end of this paper. The result shown that in term of iteration number ni and function evaluation nf, our alternative step size is more effective than the original BFGS algorithm.

ABSTRACT:
The scattering of Love waves due to a surface impedance in the surface of a vertical discontinuous surface layer is studied in the present paper. The solution of the problem is obtained when the width of the vertical disconti-nuity is very small. The reflected, transmitted and scattered waves are obtained by using the method of Fourier transformation and Wiener-Hopf technique. The numerical computations are carried out for the amplitude of the scattered waves versus wave number. There is a sharp fall of the amplitude with slight increase in the wave number.

Analysis of a Predator-Prey Model with Intraspecies Coexistence
ABSTRACT:
This paper deals with Lotka-Volterra predator-prey equations of two species. Moreover, we make assumption that, there exists coexistence within each species separately. The methods which can be used in this context are vector field, linearization and Lyapanov’s second. For each equilibrium point, stable and unstable manifolds will be determined.

Reliability analysis for two-unit system with ccs failures and human errors
ABSTRACT:
The present paper deals with the reliability analysis of two-unit identical system, which is affected by common cause shock (CCS) failures and human errors along with individual failures. The influence of CCS failures in addition to human errors is emphasized in the reliability analysis of a system. Expressions for system reliability and mean time between failures (MTBF) are developed when the system is affected by CCS failures as well as human errors. Also, these reliability indices are compared in the presence of CCS failures as well as human errors with that of the situation when CCS failures are affecting the system. Reliability Plots are shown and Numerical illustration of MTBF results is also presented to support the model.
KEYWORDS: Reliability, Mean time Between Failurs (MTBF), Common Cause Shock Failures, Human Errors
