In this work, we studied the possibility of merging proton therapy with grid therapy. We hypothesized that patients with larger targets containing solid tumor growth could benefit from being treated with this method, proton grid therapy. We performed treatment planning for 2 patients with abdominal cancer with the suggested proton grid therapy technique. The proton beam arrays were cross-fired ...

An emerging model for computational grids interconnects similar multi-resource servers from distributed sites. A job submitted to the grid can be executed by any of the servers; however, resource size or balance may be different across servers. One approach to resource management for this grid is to layer a global load distribution system on top of the local job management systems at each site....

Problem statement: In grid environment, group communication is an important mechanism to realize large-scale information resource sharing. However providing security for group communication in grid environment is very difficult because the group is dynamic in nature. Scalable group re-keying is one of the important issues in secure group communication. These group keys should be updated wheneve...

This paper summarizes operational experience and improvements in ATLAS computing infrastructure in 2010 and 2011. ATLAS has had 2 periods of data taking, with many more events recorded in 2011 than in 2010. It ran 3 major reprocessing campaigns. The activity in 2011 was similar to 2010, but scalability issues had to be addressed due to the increase in luminosity and trigger rate. Based on impro...

We present a distributed version of IDA* search algorithm for a computational grid. We also propose a grid architecture based on a multi-agent system paradigm applied to mobile devices on a cellular network. The proposed algorithm is specifically designed to adapt to the flexible environment of the grid. In this paper, we discuss several aspects of the distributed IDA* algorithm and the underly...

Smart grid is a new developing concept in power system. This technology observes the state of power system and intelligently take decisions to quickly clear faults, restores power and monitor demand to preserve the stability and performance of the electric power network formerly done by engineers. This paper discusses the technologies of smart grid and presents a developed model to illustrate t...

More than 1/3 of the EU's power will need to be generated from Renewable Energy Sources (RES) in 2020. This implies a profound transformation of Europe's energy system, grid and markets. The integration of distributed and micro generation in the electricity grid will provide more options for Distribution System Operators (DSOs) to balance their grid areas on the Medium Voltage (MV) and Low Volt...

The traditional approach in electric generation is focused on centralized plants producing electricity which is transmitted and distributed over long distances through the networks. In contrast, using distributed energy resources, much smaller amounts of energy are produced by numerous small, modular energy conversion units, which are often located close to the point of use. Therefore, Distribu...

In this paper, we evaluate strategies of domain decomposition in Grid environment to solve mesh-based applications. We compare the balanced distribution strategy with unbalanced distribution strategies. While the former is a common strategy in homogenous computing environment (e.g. parallel computers), it presents some problems due to communication latency in Grid environments. Unbalanced decom...
