The study of the reservoirs of small bodies in the Solar-System can help us to refine the theory of the origin and evolution of the whole planetary system we live in. With our work, we attempt to contribute to the general endeavor of the researchers in the topic to work out a unified theory of the formation of all small-body reservoirs and, at the same time, the last stage of the jovian-planet...

ThIS is a Therapeutic Irradiation Simulator for cancer therapy which is now being integrated into the OpenGATE project. It computes the 3D dose distribution resulting from an irradiation with carbon ion beams. The simulator has been ported on the EGEE Grid for computational speed-up. The porting methodology was presented at EGEE’08. We would now like to present current activity as well as an...

The increase in grid resources and workload calls for scalable administration tools, paving the way toward autonomic grids [1-2]. A pre-requisite for an autonomic grid, namely modelling the complex interactions between the grid middleware and the e-scientist queries, is achieved via streaming the EGEE gLite operational data. These models, supported by the Grid Observatory clusters, are meant...

Neoclassical transport for the TJ-II stellarator can be calculated by means of Drift Kinetic Equation (DKE) solvers. A computational version adapted to this stellarator was based on the work published by van Rij and Hirshman (Phys.
