In the high-frequency region, the mixed scheme of the linear and WENO schemes is adopted with the smoothness amplification factor, which could capture high-frequency wave efficiently. Spectral analysis and numerous examples are presented to demonstrate the robustness and performance of the hybrid ...
To enhance the performance of the third-order weighted essentially non-oscillatory (WENO) scheme on the four-point stencil, a new hybrid central-type scheme is proposed in this paper. Developments are conducted in the following two aspects. First, a new fourth-order central WENO scheme, named ...
In the past few decades, the weighted essentially non-oscillatory (WENO) scheme has been widely used in mesh-based methods and has achieved great success, but its application to the smoothed particle hydrodynamics (SPH) is still limited. In this paper, a simple and accurate implementation of th...
And some other famous WENO schemes are proposed for specifical computation needs, such as optimized WENO schemes for solving linear waves with discontinuity [23], monotonicity preserving WENO schemes for very high order accuracy simulation [2], hybrid compact WENO schemes for computing shock and ...
To reduce the uncertainty introduced by the noise data in classification problem, Yao et al.15 propose a new hybrid integrated credit scoring model based on stacked noise detection and weight assignment to remove or adjust the noise data in the original data 1School of Microelectronics, ...
An innovative approach is proposed to construct a WENO (Weighted Essentially Non-Oscillatory) scheme by using a hybrid power-exponential polynomial interpolation. As a result, the Taylor series expansions of the weight functions around the smooth regions can be analytically determined. These Taylor expa...

A hybrid scheme is developed for direct numerical simulations of hypersonic flows over a blunt body. The scheme switches to the first-order AUSMPW+ scheme
In this paper, high-order Runge-Kutta discontinuous Galerkin (RKDG) methods with multi-resolution weighted essentially non-oscillatory (WENO) limiters are designed for solving hyperbolic conservation laws on triangular meshes. These multi-resolution WENO limiters are new extensions of the associated multi...
On non-uniform grids, the proposed scheme is much more accurate than the original WENO-JS scheme, which was designed for uniform grids. When the grid is uniform, the resulting scheme reduces to the original WENO-JS scheme. In the meantime, the proposed scheme is computationally much more ...
