The supercomputer at the lab, expected to be completed by 2004, will use its 130,000 processors to simulate physical phenomena like the aging of materials, fires and explosions, potentially useful in safety and security planning.
Aging of materials can have significant effects on the structural performance of highway bridges.
While aging of materials was clearly observed in a reduction of denitrification by 60 70% during the experiment, systems still worked very well until the end of the experiment.
Ageing of materials or pre-treatment through leaching is needed prior to their use in construction to avoid peak concentrations.
Photoirradiation in an oxygen ambient causes photo-oxidation at the surface and thus accelerates aging of the material.
In the study, both Optim and Pursil 35 were exposed in laboratory tests to water and heating techniques aimed to accelerate aging of the materials.
Therefore, a better understanding of the processes contributing to thermal aging of these materials is of crucial importance.
We apply the FPKMC algorithm to the challenging problem of simulation of long-term irradiation of metals, relevant to the performance and aging of nuclear materials in current and future nuclear power plants.
When studying the ubiquitous and practically significant phenomena of annealing or aging of carbon materials, it is instructive to distinguish the reduction of site (re)activity from a decrease in the concentration of (re)active sites.
In other circumstances, time trend effects can be caused by learning effects of the test subjects in behavioural and life sciences, heating or ageing of material in prototype experiments, etc.
Mean age theory extends the usefulness of the concept by providing spatial distributions of the mean age of material inside a system using an innovative steady-state approach that incorporates time as a passive scalar, but has been limited to single phase systems.
