The UDAPAC Project - Uccle Direct Astronomical Plate Archive Centre: A New International Facility for Inherited Observations
We discuss a project to create a centralized astronomical direct-plate archive and digitizing facility, with a view to making photographic data fully... -
Aladin in the VO Context
Aladin, the CDS interactive sky atlas is one of the important interoperability tools of the astronomy Web. Several recent improvements prepare it for... -
The Russian Virtual Observatory Portal. Convenience and Attractiveness
Nowadays Web-site designers pay more attention on attractiveness in the presentation and convenient work with offered information for site users.... -
The Real Astronomy Experience: Making the IVO Effective for International Planetaria and Science Centers
The Real Astronomy Experience, or RAE, is a new exhibit just beginning development in the late fall of 2002, hopefully to be funded by the US... -
iAstro: Computational and Information Infrastructure in the Astronomical DataGrid
The iAstro network is a European action supported by the COST program, to foster coordination in the domain of computational and information... -
The Great Observatories Origins Deep Survey: A VO Test Case?
The Great Observatories Origins Deep Survey is an effort to orchestrate limiting observations of a northern (HDF-N) and a southern (CDF-S) field,... -

Emergence of Complexity in Financial Networks
We present here a brief summary of the various possible applications of network theory in the field of finance. Since we want to characterize... -
Characteristics of Biological Networks
Network principles describe uniformly systems as diverse as the cell or the Internet. The emergence of these networks is driven by self-organizing... -
Classes of the Shortest Pathway Structures in Scale Free Networks
We study a problem of data packet transport between a pair of vertices on scale-free network, and introduce load of a vertex as the accumulated sum... -
The Optimal Pathin an Erdős-Rényi Random Graph
We study the optimal distance $\ell_{\mbox{\scriptsize opt}}$ in... -
Information Dynamics in the Networked World
We review three studies of information flow in social networks that help reveal their underlying social structure, how information spreads among them... -
Clustering in Complex Networks
Real, mostly socially rooted networks have the tendency to form the simplest morphological structures observable: triangles, or in other words... -
Boolean Modelingof Genetic Regulatory Networks
Biological systems form complex networks of interaction on several scales, ranging from the molecular to the ecosystem level. On the subcellular... -
Nonlinear Instabilities in TCP-RED
With the growing size and popularity of the Internet, congestion control has emerged as an important problem. Poor management of congestion can... -
Dynamics of Congestion Control
One reason for the success of TCP and its widespread usage in the Internet is its ability to control network congestion. A TCP source uses implicit... -
Statistical Properties of Chaos in Communication Networks
The behavior of communication networks, like the Internet is complex in many ways. This complexity may have many origins, including the topology of... -
2. Analysis of Switched and Impulsive Systems
The analysis will focus on the case where the switchings are governed by a finite state machine. This is because the common Lyapunov function method... -
Modeling TCP/RED: a Dynamical Approach
Today’s Internet applications, such as World Wide Web, file transfer, Usenet news, and remote login, are delivered via Transmission Control Protocol...
