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... -
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... -
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... -
Visualisation Tools for Very Large Amounts of Data
Can we perceive a billion stars? How would you go about classifying them? How quantitatively good would your analysis be? How reliable would your... -

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... -
Federation and Fusion of Astronomical Information: Standards and Tools for the Virtual Observatories
We present a review of the current organization of astronomical archives and data centers in terms of data federation. We point the challenges faced,... -
Meeting the User Science Challenge for a Virtual Universe
The AstroGrid project, a core UK eScience programme, is rapidly implementing the UK’s contribution to the global drive towards the Virtual... -
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... -
Power Spectrum for the Distribution of Galaxies on the Sphere
A method of Gorski of calculation of the power spectrum for CMB for incomplete COBE data set is applied to the distribution of galaxies on the... -
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,... -
The World Space Observatory (WSO/UV) Archive: Requirements for Interoperation
The World Space Observatory (WSO/UV) is a space project for an ultraviolet telescope which has to fulfill the needs and scientific requirements of a... -
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... -
Applicability of Emerging Resource Discovery Standards to the VO
The Virtual Observatory (VO) will be one of the first applications belonging to a new generation of network services which are commonly referred to... -
Classification of Active Objects in the Multiwavelength Parametric Space
In this paper, we apply two algorithms for clustering analysis: support vector machines (SVMs) and learning vector quantization (LVQ) to classify... -
A Galactic Model as a Useful Tool for Virtual Observatories
Many observational data will be available through Virtual Observatories, but at some wavelengths and in some directions, no data yet exist.... -
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...
