Mathematics, 2022 The unsteady flow of biological liquid through non-uniform pumps under porosity impacts is considered. The Jeffrey fluid is used as blood in the current study, which is also characterized as viscoelastic fluid because of its dual characteristics: on the ...

A simple Cartesian scheme for compressible multimaterials [PDF]
, 2014 We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly different physical properties and constitutive laws, describing for example

Numerical Schemes for Signature Kernels
SIAM Journal on Numerical AnalysisAbstract. Signature kernels have become a powerful tool in kernel methods for sequential data. In “The Signature Kernel is the solution of a Goursat PDE” [ 35 ], the authors introduced a kernel trick showing that, for continuously differentiable paths, the signature kernel satisfies a hyperbolic PDE of Goursat type in two independent ...

Fractional-Calculus Analysis of the Dynamics of a Vector-Borne Infection with Preventive Measures
Fractal and FractionalVector-borne infections pose serious public health challenges due to the complex interplay of biological, environmental, and social factors. Therefore, comprehensive approaches are essential to mitigate the burden of vector-borne infections and minimize ...

Parametrized numerical scheme for the Einstein equations
JSIAM Letters, 2021 Summary: In astrophysics and astronomy, it is necessary to solve numerically and accurately the Einstein equations, which are 2nd-order partial differential equations for a metric. We propose a method of estimating a numerical scheme in terms of constraints, and we also demonstrate that a numerical scheme with parameters makes it possible to perform a ...

Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]
, 2013 We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

Numerical modelling of dense snow avalanches with a well-balanced scheme based on the 2D shallow water equations [PDF]
, 2023 A common technique for simulating non–Newtonian fluid dynamics, such as snow avalanches, is to solve the Shallow Water Equations (SWE), together with a rheological model describing the momentum dissipation by shear stresses.
