Conservation Laws with Time Dependent Discontinuous Coefficients [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2005
The authors consider scalar conservation laws where the flux function depends discontinuously on both the spatial and temporal locations. The existence and well-posedness of an entropy solution to the Cauchy problem are proved. The existence is established by showing that a sequence of front tracking approximations is compact in \(L^1\), and that the ...

Efficacy of applying discontinuous boundary condition on the heat transfer and entropy generation through a slip microchannel equipped with nanofluid

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
In this study, the laminar nanofluid flow in the microchannel with a discontinuous-boundary condition was investigated. Considering the slip condition, heat transfer and entropy generation were studied.

Convergence of fully discrete schemes for diffusive dispersive conservation laws with discontinuous coefficient [PDF]

open access: yes, 2015
We are concerned with fully-discrete schemes for the numerical approximation of diffusive-dispersive hyperbolic conservation laws with a discontinuous flux function in one-space dimension. More precisely, we show the convergence of approximate solutions,

The Gini coefficient and discontinuity

open access: yesCogent Economics & Finance, 2022
This article reveals a discontinuity in the mapping from a Lorenz curve to the associated cumulative distribution function. The problem is of a mathematical nature—based on an analysis of the transformation between the distribution function of a bound random variable and its Lorenz curve.

A note on strong solutions of stochastic differential equations with a discontinuous drift coefficient [PDF]

open access: yes, 2006
The existence of a mean-square continuous strong solution is established for vector-valued Itö stochastic differential equations with a discontinuous drift coefficient, which is an increasing function, and with a Lipschitz continuous diffusion ...

An approximation scheme for an Eikonal Equation with discontinuous coefficient [PDF]

open access: yes, 2013
We consider the stationary Hamilton-Jacobi equation where the dynamics can vanish at some points, the cost function is strictly positive and is allowed to be discontinuous. More precisely, we consider special class of discontinuities for which the notion

Stable Determination of the Discontinuous Conductivity Coefficient of a Parabolic Equation [PDF]

open access: yes, 2009
We deal with the problem of determining a time varying inclusion within a thermal conductor. In particular we study the continuous dependance of the inclusion from the Dirichlet-to-Neumann map.

On Discontinuous Galerkin Methods for Elliptic Problems with Discontinuous Coefficients [PDF]

open access: yesComputational Methods in Applied Mathematics, 2003
AbstractDiscontinuous Galerkin methods for elliptic problems with discontinuous coefficients are discussed. First the error bound of the methods is analyzed. Then a multilevel additive Schwarz preconditioner for one of the discrete problems is designed and analyzed.

Effect of particle restitution coefficient on high-power gear transmission with dynamic continuum and non-continuum coupling

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
High-power gears are widely used in various engineering fields. A gear transmission system is an extremely complex elastic system that produces complex vibrations under internal and external excitation. In this study, the excitation value in the gear was
