Dynamic disorder is modeled by white Poisson noise. Models with site-independent (global) and site-dependent (local) disorder are considered. Results are described in terms of an affective random walk in a nondisordered medium. In the cases of global disorder the effective random walk contains ...
Random walk is a stochastic process, which describes a path by using the additive sum previous values and white noise. Gaussian random walk is one particular type of it which uses a set of random variables known to follow normality. Answer and...
. the random walk starts at the origin and jumps in discrete time. at the moment of a jump, it inspects the environment exactly in the site where it lies on. if the site is vacant, the random walk decides to jump to the right with probability \(p_{\circ }\) and to the left wi...
This type of random process is called a random walk and occurs whenever a white noise is integrated over time. While not correct from the color spectral parallel, red 1/f 2 noise is sometimes referred to as Brown noise, in honor of Robert Brown who first studied Brownian motion. Figure 4...
The advantage to random walk models: Within the fractional approach it is possible to include external "elds in a straightforward manner. Also the consideration of transport in the phase space spanned by both position and velocity coordinate is possible within the same approach. Moreover, ...

Also, all statistics are averaged over one hundred simulations unless the walk was deterministic in which case only one simulation was needed. Although the sample space is exponential in size, averaging over an exponential number of simulations is not feasible; however, one hundred simulations is ...

Independently of all else, the walk takes an exponential time with rate μ. (a) What is the distribution of the time at which the last rider departs the car? (b) Suppose the last rider departs the car at time t. What is the probability that all the other riders are home at that ...
be the probability that a simple random walk in \({\mathbb {z}}^d\) starting from 0 returns to 0 before escaping to \(\infty \) . the values of \(\alpha _0(d)\) and \(\alpha _1(d)\) from theorem 1.1 are explicitly given by $$\begin{aligned} \alpha _0(d) = \...
