Machine learning based prediction of carbon concentration in carburized steel [PDF]
Scientific ReportsThe carbon concentration and hardness of a part’s surface can be enhanced through the carburizing-quenching process. The mechanical properties are affected by the carbon concentration distribution in the surface layer, which directly determines wear ...

Quenching for discretizations of a semilinear parabolic equation with nonlinear boundary outflux
Journal of Numerical Analysis and Approximation Theory, 2023 In this paper, we study numerical approximations of a semilinear parabolic problem in one-dimension, of which the nonlinearity appears both in source term and in Neumann boundary condition.

Time-dependent numerical renormalization group method for multiple quenches: Towards exact results for the long-time limit of thermodynamic observables and spectral functions [PDF]
Physical Review B, 2018 We develop an alternative time-dependent numerical renormalization group (TDNRG) formalism for multiple quenches and implement it to study the response of a quantum impurity system to a general pulse. Within this approach, we reduce the contribution of the NRG approximation to numerical errors in the time evolution of observables by a formulation that ...

Fundamental Journal of Mathematics and Applications, 2020 In this paper, we study the numerical methods for solving a nonlinear reaction-diffusion model for the polarization phenomena in ionic conductors. In particular, we propose three types of numerical methods, including the finite difference, cubic B-spline collocation, and local discontinuous Galerkin method, to approximate the quenching time of the ...

Quenching for a Reaction-Diffusion System with Coupled Inner Singular Absorption Terms
Boundary Value Problems, 2010 we devote to investigate the quenching phenomenon for a reaction-diffusion system with coupled singular absorption terms, ut=Δu−u−p1v−q1, vt=Δv−u−p2v−q2.

Uniform quenching processes in a holographic s + p model with reentrance
European Physical Journal C: Particles and Fields, 2021 We study the homogenous quenching processes in a holographic s + p model with reentrant phase transitions. We first realize the reentrant phase transition in the holographic model in probe limit and draw the phase diagram.

How parametric resonance mechanism follows quench mechanism in disoriented chiral condensate [PDF]
, 2001 We show how parametric resonance mechanism follows quench mechanism in the classical linear sigma model. The parametric resonance amplifies long wavelength modes of the pion for more than $10 fm/c$.

Generation and Quenching of Intensity Pulsations in Semiconductor Lasers Coupled to External Cavities [PDF]
, 1980 The behavior of self-pulsing and nonpulsing lasers coupled to external cavities is investigated experimentally and theoretically. We investigate the dependence of the pulsation characteristics on the external cavity length using a saturable absorber ...
