Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... En savoir plus
The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides ... En savoir plus
RFID tags are ever increasing in their daily use, from the monitoring of components, the tracking of produce during processing & production, as well as being used in much of the touch-less technologies seen today. With this technology, there has been the ever increasing need to ... En savoir plus

Accurate thermo-physical properties of materials are valuable for both scientific research and industrial applications. For high temperature liquid materials, two issues exclude traditional methods: elevated reactivity of test material and experimental apparatus, uncontrolled heat ... En savoir plus
The main purpose of a drive unit is to transform the electrical signal at its terminals into acoustic waves via two transduction mechanisms: electro-mechanical and mechano-acoustical. In this paper only the electro-mechanical transformation is discussed in view of a future optimization ... En savoir plus
The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used ... En savoir plus
According to the National Health and Nutrition Examination Survey data, 35 % of US adults aged 40 years and older have evidence of balance dysfunction based on the modified Romberg test. In this vestibular dysfunction, patients are not able to see stabilized images on their retina during ... En savoir plus
