Evolution of the Internet Topology and Traffic Dynamics of Data Packets
In recent years, the Internet has become one of the most influential media in our daily life, going beyond in its role as the basic infrastructure in... -
9. Switched Scalable Video Coding Systems
Scalable video coding means that a video sequence is only encoded once and the coded bitstream has the capability of sending any sub-bitstream... -
4. Stability of Nonlinear Switched and Impulsive Systems
In this chapter, we shall study the stability of nonlinear switched and impulsive systems of the form... -
1. Examples and Modelling of Switched and Impulsive Systems
When you begin to read this book, you may ask: “what is a switched and impulsive system?” This is a question that may be best answered through... -
Synchronization in Complex Networks
The study of complex systems pervades all of science, from cell biology to ecology, from computer science to meteorology. A paradigm of a complex... -
Data Traffic, Topology and Congestion
We consider the interaction between the topology of a network and the tra.c carried along its channels. The binding elements between the topology and... -
VO Activities at the Harvard-Smithsonian CfA
This paper summarizes the VO activities at the Harvard-Smithsonian Center for Astrophysics (CfA). Cfa has expertise covering virtually all branches... -
A C + + Parser for VOTables
This paper provides a brief description of C + + Parser for VOTables. The parser is developed by Persistent Systems in association with IUCAA as part... -
Automatic Detection-Extraction-Classification for a Large Number of Stellar Spectra from Slitless Wide Field Spectroscopy. A Project for AVO
The distribution of spectral types in extended stellar systems in galaxies can be a powerful mine of information regarding:... -

The Astronomical Data Warehouse
The idea of the astronomical data warehouse has arisen as the natural extension of current trends in astronomical data archives, and from an analysis... -
Building the Infrastructure for the National Virtual Observatory: An Information Technology Research Initiative of the National Science Foundation
The U.S. National Science Foundation is sponsoring the development of the infrastructure for the National Virtual Observatory via its Information... -
Information Hub of the Russian Virtual Observatory
The ultimate goal of the Russian Virtual Observatory (RVO) initiative is to provide every astronomer with on-line access to the rich volumes of data... -
Building Interoperable NASA Archives
Over the past decades NASA has developed an extensive set of archives for space astronomy data. These archives are organized along mission,... -
Using XML-Schema to Model Data from Present and Future Astronomical Databases
XML (eXtensible Markup Language) has now become an almost inescapable tool for the exchange of formatted data over the World Wide Web and is now... -
Wide-Field X-Ray Monitoring as a Data Source for the Virtual Observatory
We refer on novel X-ray telescopes with high sensitivity as well as large field of view of order of 1 000 square degrees or even more. The results... -
Laplacean Ideology for Preliminary Orbit Determination and Moving Celestial Body Identification in Virtual Epoch
Any CCD frames with stars or galaxies or clusters and other images must be studied for a searching of moving celestial objects, namely asteroids,... -
HyperLeda: Virtual Instruments for Extragalactic Astronomy
HyperLeda offers a series of tools of interest for Galactic and extra-galactic astronomy. The most prominent service is the LEDA catalogue which... -
A Practical Approach to Catalogued-Data Visualisation
Catalogued data is one of the ways information will be collected from VO. The selected material will contain many physical quantities (columns) and... -
Development of a Multi-Mission Data Server at LAEFF
Astronomical archives have been built independently of each other showing a variety of access levels and policies. This has caused that their remote...
