Assessment and Comparative Study of Free and Commercial Numerical Software Packages for Lithium‐Ion Battery Modeling

open access: yesAdvanced Theory and Simulations, EarlyView.
This study evaluates the simulation capabilities of lithium‐ion battery (LIB) electrochemical simulation software packages. The benchmark simulation results reveal the impacts of parameter sensitivity to solver performance and stability. The guidelines to troubleshooting common solver failures at high current rates lowers the steep learning curve to ...

Studying behavior of the asymptotic solutions to P-Laplacian type diffusion-convection model [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة
The rescaling method is presented to allow us to establish nonnegative local solutions to the evolution of the Cauchy problem (CP) of the nonlinear degenerate parabolic p-Laplacian process with conservation laws that are posed in one-dimensional space ...

Modeling Electrical Transport in Random Networks Composed of Metal‐Oxide Nanowires: The Transition from Junction‐Dominated to Nanowire‐Dominated Regime

open access: yesAdvanced Theory and Simulations, EarlyView.
This study proposes a model for the electrical transport properties of random networks of metal oxide nanowires. Based on the characteristic lengths and energies of nanowires, it allows for discussing the transition from the junction‐dominated to the nanowire‐dominated transport regime.

Finite Speed of Propagation and Waiting Time Phenomena for Degenerate Parabolic Equations with Linear Growth Lagrangian

open access: yesSIAM Journal on Mathematical Analysis, 2015
We consider a class of degenerate parabolic equations with linear growth Lagrangian. Two prototypes within this class, sharing common features with nonlinear transport equations, are the relativistic porous medium equation and the speed-limited (or flux ...

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control

open access: yesAdvanced Science, EarlyView.
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Harnack type inequality for non-negative solutions of second-order degenerate parabolic equations in divergent form

open access: yesElectronic Journal of Differential Equations, 2016
We study a class of second-order degenerate parabolic equations in divergent form. We prove two analogues of the Harnack inequality, one for non-negative weak solutions, an another for non-negative solutions.

Asymptotic behavior for parabolic equations with interior degeneracy

open access: yesExamples and Counterexamples, 2022
The long time behavior of a class of degenerate parabolic equations in a bounded domain will be considered in the sense that the nonnegative diffusion coefficient a(x)is allowed to vanish in a set of positive measure in the interior of the domain.

UNIFORM BMO ESTIMATE OF PARABOLIC EQUATIONS AND GLOBAL WELL-POSEDNESS OF THE THERMISTOR PROBLEM

open access: yesForum of Mathematics, Sigma, 2015
We prove global well-posedness of the time-dependent degenerate thermistor problem by establishing a uniform-in-time bounded mean ocsillation (BMO) estimate of inhomogeneous parabolic equations.
