The quasi-elastic scattering of 1 GeV protons permits the three-dimensional reconstruction of the density distribution in extended bodies. Fast multiwire proportional chambers are used to localize the position of every incoming and outgoing charged particle and to determine the coordinates at the interaction vertex. This article describes tests on a human(More)

The Kepler scientific workflow system enables creation, execution and sharing of workflows across a broad range of scientific and engineering disciplines while also facilitating remote and distributed execution of workflows. In this paper, we present and compare different approaches to distributed execution of workflows using the Kepler environment,(More)
The Integrated Tokamak Modelling Task Force (ITM-TF) is developing an infrastructure where the validation needs, as being formulated in terms of multi-device data access and detailed physics comparisons aiming for inclusion of synthetic diagnostics in the simulation chain, are key components. A device independent approach to data transport and a(More)
The development of X-ray CT scanning has led to interest in other methods of reconstructive tomography. CT scanning is essentially an anatomic method. With the help of a positron camera, gallium 68 allows us to study the blood-brain barrier, ammonia 13 blood flow. This work is based upon the first experience of nuclear scattering radiography. Three main(More)
This paper describes chosen aspects of the European Integrated Tokamak Modelling Task Force (ITM-TF) effort. It covers topics related to latest developments towards providing fusion scientists with a software framework for fusion modeling and simulation. The proposed framework provides researchers with an easy to use, workflow based environment for(More)
Facing computing and data intensive problems scientists are forced to use all the available resources to solve their problems. This applies to the usage of different distributed e-Infrastructures based on different concepts and architectures. Providing the end user with easy access to such complex systems is a very challenging task and refers to the issues(More)
