Historians have persistently likened strike waves to wildfires, avalanches, and epidemics. These phenomena are characterized by a power-law distribution of event sizes. This kind of analysis is applied to outbreaks of class conflict in Chicago from 1881 to 1886. Events are defined as individual strikes or miniature strike waves; size is measured by the number of establishments or workers involv...

Whether there are universal laws or principles in complex systems is a fascinating and important question. Prof. John Casti uses the case of Normal Distribution (\bell curves") to illustrate that such universal principle is perhaps out there waiting to be discovered [1]. He suggests Zipf's law as a candidate for such universal principle. But as the author of one of the three publications to pro...

It is widely believed that the Internet’s AS-graph degree distribution obeys a power-law form. Most of the evidence showing the power-law distribution is based on BGP data. However, it was recently argued that since BGP collects data in a tree-like fashion, it only produces a sample of the degree distribution, and this sample may be biased. This argument was backed by simulation data and mathem...

The degree distributions of many real world networks follow power-laws whose exponents tend to fall between two and three. Within the framework of the Barabási-Albert model (BA model), we explain this empirical observation by a simple fact. To that end we propose a modified BA model with one parameter that serves as a regulatory factor for the growth rate of added links in scale-free networks. ...

The 2-parameter family of probability distributions introduced by Birnbaum & Saunders characterizes the fatigue failure of materials subjected to cyclic stresses and strains. It is shown that the methods of accelerated life testing are applicable to the Birnbaum–Saunders distribution for analyzing accelerated lifetime data, and the (inverse) power law model is used due to its justification for ...

In this paper, we propose a methodology for estimating the statistics of the intercell interference power in the downlink of a multicellular network. We first establish an analytical expression for the probability law of the interference power when only Rayleigh multipath fading is considered. Next, focusing on a propagation environment where small-scale Rayleigh fading as well as large-scale e...

The present research deals with the flexural-torsional buckling analysis of sandwich web and/or flanges tapered doubly-symmetric I-beam. All section walls are composed of two metal face layers and a functionally graded (FG) porous core. It is assumed that the material properties of the porous core vary gradually in the longitudinal direction according to the simple power-law function considerin...
