Secret distribution and erasure convention based approaches have been used in distributed storage systems to provide the confidentiality, integrity, and availability of critical information. To achieve performance goals in data accesses, these data fragmentation approaches can be combined with dynamic replication. In this paper, we consider data partitioning (both secret distribution and erasur...

background: an effective method for management of large and bulky malignant tumors. this treatment modality is also known as specially fractionated radiation therapy (sfrt). in this treatment technique a grid block converted the open radiation field into a series of pencil beams. dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and mo...

The last advances in computation have made feasible the resolution of very complex problems. Grid computing has matured to currently become one of the most successful initiatives for dealing with these challenging problems, which usually require tackling huge volumes of data. Although the main goal of the grid technology is sharing resources among several virtual organizations, few research wor...
