The primary failure mechanism in brittle materials such as ceramics, granite and some metal alloys is through the presence of defects which result in crack formation and propagation under the application of load. We are interested in studying this process of crack propagation, interaction and coalescence, which degrades the strength of the specimen. Traditionally, engineering applications that study...
Model Validation Suggestions •When attempting to validate a model, these suggestions may be helpful to follow — Keep the problem simple — Choose applications that can be validated — Keep in mind, inaccurate models provide useful data
The CMS collaboration has developed a fast Monte Carlo simulation of the CMS detector with event production rates ~100 times faster than the GEANT4-based simulation, with comparable accuracy for most of the high level observables to be used in the physics analyses. We discuss basic technical principles of the CMS Fast Simulation and their implementation in the different components of the detector:...
The ATLAS experiment, operational at the new LHC collider, is fully simulated using a Geant 4-based simulation program within the ATLAS Athena framework. This simulation software is used for large-scale production of events on the LHC Computing Grid as well as for smaller-scale studies. Simulation of ATLAS requires many components, from the generators that simulate particle collisions to packages...
The FLUKA Monte Carlo code has been widely applied and benchmarked in recent years to problems related to Galactic Cosmic Rays (GCR) and Solar Energetic Particle (SEP) events. Applications range from fundamental cosmic ray and neutrino physics, to doses to commercial aircraft and space radiation issues in low orbit or in deep space. The main results of interest for fundamental physics concern the...
Advances in Internet connections speeds and computer hardware means that web content has grown richer and more interactive for users. One such area is Web3D which has seen the emergence of ISO standard technologies such as VRML (Virtual Reality Modeling Language) and its XML-based (eXtensible Markup Language) successor X3D(eXtensible 3D). X3D, in particular, presents opportunities for further integration...
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...
