On the ideal weights for WENO/WENO-like finite difference schemes for the first derivative, I [PDF]
International Journal of Modern Physics C, 2020 An interesting fact which was used in the construction of targeted essentially non-oscillatory (TENO) schemes is that a [Formula: see text]th order accurate scheme can be written as a linear combination of two [Formula: see text]th order accurate schemes.

Efficient WENO library for OpenFOAM
SoftwareX, 2020 The weighted essentially non oscillating (WENO) concept is well established in research and its advantages are known, however, implementation details such as memory demand hindered the usage for general applications and general purpose libraries for many

Embedded WENO : a design method to improve existing WENO schemes [PDF]
, 2015 Embedded WENO methods utilize all adjacent smooth substencils to construct a desirable interpolation. Conventional WENO schemes underuse this possibility close to large gradients or discontinuities. Embedded methods based on the WENO schemes of Jiang and Shu [1] and on the WENO-Z scheme of Borges et al. [2] are explicitly constructed.

High-Order Embedded WENO Schemes
, 2017 Embedded WENO schemes are a new family of weighted essentially nonoscillatory schemes that always utilise all adjacent smooth substencils. This results in increased control over the convex combination of lower-order interpolations. We show that more conventional WENO schemes, such as WENO-JS and WENO-Z (Borges et al., J. Comput.

Zhongguo Jianchuan Yanjiu, 2018 [Objectives] In this paper, an improved third-order WENO scheme named ‘WENO-N+3’ is constructed by adding a suitable term to the weights of the conventional WENO-N3 scheme.

AIP Advances, 2022 In the present study, a high-order high-resolution energy stable weighted essentially non-oscillatory plus (ESWENO-P) scheme was developed by improving the weighting function in the energy stable weighted essentially non-oscillatory (ESWENO) scheme ...

New Constructing Method for WENO Schemes [PDF]
, 2013 A new method for constructing weighted essentially non-oscillatory (WENO) scheme is proposed. The idea of this method is to combine Henrick's mapping function and the idea of improving the accuracy of WENO-Z scheme one-by-one order.

New More Efficient A-WENO Schemes
Journal of Scientific Computing, 2023 We develop new more efficient A-WENO schemes for both hyperbolic systems of conservation laws and nonconservative hyperbolic systems. The new schemes are a very simple modification of the existing A-WENO schemes: They are obtained by a more efficient evaluation of the high-order correction terms.

Sinogram-based flow estimation in computed tomography using a physics-informed neural network: Impact of gantry rotation speed, X-ray fluence and pulsed acquisition on accuracy. [PDF]
Med PhysAbstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...
