One of the main challenges in molecular biology is the management of data and
databases. A large fraction of the biological data produced is publicly available on
web sites or by ftp protocols. These public databases are internationally known and
play a key role in the majority of public and private research. But their
exponential
growth raises an usage problem. Indeed, scientists need easy

In this paper, we present a web protal that enables simulation of MRI images on the
grid. Such simulations are done using the SIMRI MRI simulator that is implemented on
the grid using MPI. MRI simulations are useful for better understanding the MRI
physics, for studying MRI sequences (parameterisation), and validating image
processing algorithms. The web portal client/server architecture i

1.Introduction
In the 70s, the transition from batch systems to interactive computing has been the
enabling tool for the widespread diffusion of advances in IC technology. Grids are
facing the same challenge. The exponential coefficients in network performance
enable the virtualization and pooling of processors and storage; large-
scale user involvement might require seamless integration

Data audification is the representation of data by sound signals; it can be considered as the acoustic
counterpart of data graphic visualization, a mathematical mapping of information from data sets to sounds.
Data audification is currently used in several fields, for different purposes: science and engineering, education
and training, in most of the cases to provide a quick and effective dat
