In this article, I describe a renormalization group approach for complex networks, as applied by Rozenfeld et.al. in 1. A large number of naturally occuring networks are scale-free, i.e. display a powerlaw degree distribution 2. Moreover, many of these networks display both the small world property, and fractal characteristics. The RG approach demonstrates a transition between fractal and small...

Small-world networks are ubiquitous in nature and society, describing such diverse systems as the World Wide Web, the neuronal network of the worm C. elegans, and the friendship network. Most small-world models are stochastic, that is, they create networks where the nodes appear to be randomly connected to each other. Here we propose a simple model that generates a small-world network in a simp...

The system of distribution of goods and services, along with other economic developments around the world, is rapidly evolving. In the world of distribution of goods, the main focus is on making distribution operations more effective. Due to the fact that the cross-dock has the advantage of removing intermediaries and reducing the space required for the warehouse, it is worth considering. Among...

Using the national income expenditure distribution data from 111 countries, we decompose total inequality between the individuals in the world, by continents and regions. We use Yitzhaki’s Gini decomposition which allows for an exact breakdown of the Gini. We find that Asia is the most heterogeneous continent; between-country inequality is much more important than inequality in incomes within c...

In this paper, we studied the research areas of Chinese natural science basic research from a point view of complex network. Two research areas are considered to be connected if they appear in one fund proposal. The explicit network of such connections using data from 1999 to 2004 is constructed. The analysis of the real data shows that the degree distribution of the research areas network (RAN...

sir, at the beginning of the 21 st century, the third millennium, the pandemic flu a (h1n1) occurred. between mid march and mid april 2009, a pandemic influenza a virus emerged in mexico. [1] the disease spread very quickly in different parts of the world. it has to be said that the disease infected millions of population in different continents and killed at least 18449 people, [2] but less th...

The wide popularity of Kerberos made it the de-facto standard for authentication in enterprise networks. Moreover, the lightweight nature of Kerberos makes it a candidate of choice for securing network communications in emerging non-enterprise information systems such as industrial control networks, building automation and intelligent transportation systems. Many of these potential applications...

The draft documents a method for a Kerberos Key Distribution Center (KDC) to respond to client requests for Kerberos tickets when the client does not have detailed configuration information on the realms of users or services. The KDC will handle requests for principals in other realms by returning either a referral error or a cross-realm TGT to another realm on the referral path. The clients wi...
