For certain classes of scientific and technical computations the cloud may offer easily accessible, scalable, and affordable gigantic computing power. A power that for these classes may lead to a step change in model and analysis complexity compared to what is feasible with dedicated ... En savoir plus

In many groundwater studies, the areal extent of an aquifer is much larger than its thickness so that flow and transport take place primarily in horizontal directions. Thus, the most common type of modeling in practical applications is two-dimensional involving vertically averaged ... En savoir plus

The modeling of ferromagnetic materials is a challenging task of high industrial and academic impact. Thin film and granular systems form the basis of novel spintronic devices such as modern hard drives with a high data area storage density. In order to push the current limits even ...

Vanadium redox flow batteries (VRBs) are a promising new energy storage technology designed for use in long term applications such as uninterruptible power supply and coupling with renewable energy sources (i.e. wind and solar). Crossover is the undesired transport of vanadium ions ... En savoir plus

Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption ... En savoir plus

Hydrogen storage in a metal hydride bed, uses an intermetallic alloy that can absorb efficiently high amounts of hydrogen by chemical bonding resulting to metal hydrides. This alloy is capable of absorbing and desorbing hydrogen while maintaining its own structure. The heat, mass and ... En savoir plus

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... En savoir plus

Shielded transportation casks are commonly used for transportation and storage of radioactive waste materials. Design approval of such casks by regulatory authority is subject to its compliance with a thermal test (among other tests) Due to exposure of cask to fire , there is a ... En savoir plus

Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... En savoir plus

In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... En savoir plus
