IEEE 802.16/WiMAX is one of the most promising technologies for broadband wireless access, both for fixed and mobile use. This paper presents the structure of some testbeds, set up in the framework of the European project WEIRD, about novel applications running on top of a WiMAX-based end-to-end architecture. The presented testbeds are based on real use… (More)
In this paper medical applications on a Grid infrastructure, the MAGIC-5 Project, are presented and discussed. MAGIC-5 aims at developing Computer Aided Detection (CADe) software for the analysis of medical images on distributed databases by means of GRID Services. The use of automated systems for analyzing medical images improves radiologists' performance;… (More)
In this paper a biometric system for personal identification, realized through the manipulation of retinal fundus images and the detection of its bifurcation points, is described. In the image pre-processing step, a strong contrast exaltation between blood vessels and the background in retinal image is carried out; then blood vessels are extracted and next… (More)
BACKGROUND A fundamental activity in biomedical research is Knowledge Discovery which has the ability to search through large amounts of biomedical information such as documents and data. High performance computational infrastructures, such as Grid technologies, are emerging as a possible infrastructure to tackle the intensive use of Information and… (More)
