random walk (CTRW) approach and velocity-independent transition time distributions explain experimental data • Breakthrough curves (BTCs) at multiple flow rates are fit with true …

Montroll-Weiss theory of separable CTRW in terms of the random waiting time, moments of the position, Tauberian theorems for the Laplace transform and long-time scaling laws, normal …

2022年9月21日 · CTRW 由 Montroll 和 Weiss 引入，作为物理扩散过程的推广，以有效描述异常扩散（anomalous diffusion），即超扩散和亚扩散情况（super- and sub-diffusive cases）。 …

在数学中，连续时间随机游走（Continuous-time random walk, CTRW）是随机游走的推广，其中游荡粒子在跳跃之间等待随机时间。这是一个随机跳跃过程，跳跃长度和等待时间分布任意。

2017年6月21日 · Here, we focus on such effects when the diffusion process is described by the Continuous Time Random Walk (CTRW) model. For the case where the jump length and the …

To address random waiting times in the context of continuous time random walks (CTRWs), we will begin with a brief overview of Laplace transforms and renewal theory, including an …

2004年3月1日 · We investigate continuous time random walk (CTRW) theory, which often assumes an algebraic decay for the single transition time probability density function (pdf) ψ …

1992年10月1日 · An equivalence is established between the propagator formalism of the continuous time random walk (CTRW) theory with finite random flying times and a generalized …

In this article, we utilise the Semi-Markov property of scaling limits of CTRWs, and thus derive a computational algorithm for the calculation of the probability distributions of CTRW limit …

A numerical method based on the continuous time random walk (CTRW) theory is developed to study the normal diffusion and anomalous diffusion including both sub-diffusion and super …
