Nowadays, data is being generated, collected, and analyzed at an unprecedented scale, data integration is the problem of combining data from heterogeneous, autonomous data sources, and providing users with a unified view of integrated data. To design a data integration framework, we need to address challenges, such as schema mapping, data cleaning, record linkage, and data fusion. In this paper, we...
Radiation simulations have been widely used in high energy physics, nuclear physics, accelerator physics, medical science, and space science. The simulations generate particle trajectories and physical quantities in detectors, equipment or a human body. Therefore, visualization system has to process and draw complex and huge data in such simulations. We have been developing visualization software...
Monte Carlo-based radiotherapy simulation has been used to do a high accurate calculation of dose distributions in a patient or an optimization of the beam delivery system. Geant4 toolkit has come to be utilized to build a Monte Carlo simulator for that purpose. We have developed PTSim (Particle Therapy System) that is a simulator of particle therapy simulation based on Geant4. gMocren which is a...
In a virtual sculpture project, we would like to sculpt in real-time very large 3D objects sampled in volume elements (voxels). The drawback of this kind of representation is the important number of voxels required to represent very large and detailed objects. Consequently, that entails important memory cost and computation time issues. In order to allow real-time performance, we propose in this paper...
