An effective recruitment evaluation plays an important role in the success of companies, industries and institutions. In order to obtain insight on the relationship between factors contributing to systematic recruitment, the artificial neural network and logic mining approach can be adopted as a data extraction model. In this work, an energy based satisfiability reverse analysis incorporating a Hopfield neural network is proposed to extract the relationship between the factors in an electronic (E) recruitment data set.
View Article and Find Full Text PDFA method based on extended cubic B-spline is proposed to solve a linear system of second-order boundary value problems. In this method, two free parameters, [Formula: see text] and [Formula: see text], play an important role in producing accurate results. Optimization of these parameters are carried out and the truncation error is calculated.

- The study focuses on the numerical analysis of 2-D mixed convective boundary layer flow involving water-based nanofluids, considering various thermal and mass boundary conditions.
- It uses a finite difference method with quasi-linearization to solve transformed governing equations, revealing how skin friction, heat transfer, and mass transfer rates vary with parameters like time, frequency, and buoyancy.
- The findings are novel and could aid in optimizing thermal fluids systems for applications in space materials processing, with verified results showing good consistency with previously published data.
The generalized nonlinear Klien-Gordon equation plays an important role in quantum mechanics. In this paper, a new three-time level implicit approach based on cubic trigonometric B-spline is presented for the approximate solution of this equation with Dirichlet boundary conditions. The usual finite difference approach is used to discretize the time derivative while cubic trigonometric B-spline is applied as an interpolating function in the space dimension.

The scheme is based on the usual finite difference scheme to discretize the time derivative while cubic B-spline is used as an interpolation function in the space dimension. The scheme is shown to be unconditionally stable using the von Neumann method.

- The article presents an analytical solution for flow and heat transfer in a viscoelastic fluid within a porous-walled axisymmetric channel using the Optimal Homotopy Asymptotic Method (OHAM).
- It discusses the effects of various parameters on the fluid's velocity, temperature, friction factor, and heat transfer rates, providing graphical representations of these influences.
- The results suggest that OHAM offers a more reliable solution compared to other methods for tackling complex nonlinear heat transfer issues.
