Self-similarity of waiting times in fracture systems

Self-similarity of waiting times in fracture systems.

Experimental and numerical results are presented for a fracture experiment carried out on a fiber-reinforced element under flexural loading, and a statistical analysis is performed for acoustic emission waiting-time distributions. By an optimization procedure, a recently proposed scaling law describing these distributions for different event magnitude scales is confirmed by both experimental an...

Waiting times in polling systems with various service disciplines

We consider a polling system of N queues Q1, . . . , QN , cyclically visited by a single server. Customers arrive at these queues according to independent Poisson processes, requiring generally distributed service times. When the server visits Qi, i = 1, . . . , N , it serves a number of customers according to a certain visit discipline. This discipline is assumed to belong to the class of bran...

Feedback control of waiting times.

Feedback loops are known as a versatile tool for controlling transport in small systems, which usually have large intrinsic fluctuations. Here we investigate the control of a temporal correlation function, the waiting-time distribution, under active and passive feedback conditions. We develop a general formalism and then specify to the simple unidirectional transport model, where we compare cos...
