Accurate ENO-like schemes for the model of fluid flows in a nozzle with variable cross-section [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
A class of accurate high-order $ENO$-like schemes for the model of fluid flows in a nozzle with variable cross-section is presented. The model contains a nonconservative source term, which causes unsatisfactory results to standard numerical schemes, even

The Information Bottleneck’s Ordinary Differential Equation: First-Order Root Tracking for the Information Bottleneck

open access: yesEntropy, 2023
The Information Bottleneck (IB) is a method of lossy compression of relevant information. Its rate-distortion (RD) curve describes the fundamental tradeoff between input compression and the preservation of relevant information embedded in the input ...

Numerical Approximation of Orthogonal Maps [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
The authors discuss an operator-splitting method in the finite element methodology for the numerical solution of the Dirichlet problem for orthogonal maps. The approach combines a variational principle, the introduction of the associated flow problem, and a time-stepping splitting algorithm.

Analytical and Numerical Monotonicity Analyses for Discrete Delta Fractional Operators

open access: yesMathematics, 2022
In this paper, first, we intend to determine the relationship between the sign of Δc0βy(c0+1), for 10 (the monotonicity of y), where Δc0βy(z) will be assumed to be negative for each z∈Nc0T:={c0,c0+1,c0+2,⋯,T} and some T∈Nc0:={c0,c0+1,c0+2,⋯}.

Analysis of a HMM time-discretization scheme for a system of Stochastic PDE's [PDF]

open access: yes, 2012
We consider the discretization in time of a system of parabolic stochastic partial differential equations with slow and fast components; the fast equation is driven by an additive space-time white noise.

Numerical Approximation of Some Infinite Gaussian Series and Integrals

open access: yesNonlinear Analysis, 2008
The paper deals with numerical computation of the asymptotic variance of the so-called increment ratio (IR) statistic and its modifications. The IR statistic is useful for estimation and hypothesis testing on fractional parameter H ∈ (0, 1) of random ...

Highly Efficient Numerical Algorithm for Nonlinear Space Variable-Order Fractional Reaction–Diffusion Models

open access: yesFractal and Fractional, 2023
In this paper, we present a new highly efficient numerical algorithm for nonlinear variable-order space fractional reaction–diffusion equations. The algorithm is based on a new method developed by using the Gaussian quadrature pole rational approximation.
