Viable design alternative for the existing and fast growing UAVs which are optimized for unmanned flight is of great demand. Designing of a small scale UAV alternative to the AAI Aerosonde UAV has been considered changing the wing tail configuration of the vehicle analyzing both ... En savoir plus

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, ... En savoir plus

Many liquid food processes involve coupled phenomena of fluid flow, heat transfer and product transformation. A typical example is the heat treatment of a starch suspension inside a tubular heat exchanger. Fluid flow influences heat transfer which determines temperature evolution along ... En savoir plus

The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... En savoir plus

Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group ... En savoir plus

An ISFET is an ion-sensitive field effect transistor used to measure ion concentrations in a solution; when the ion concentration changes, the current through the transistor will change accordingly. Here, the solution is used as a gate electrode. A voltage between substrate and the oxide ... En savoir plus

This paper proposes a framework for an efficient integration between geometric modeling program and analysis tool for a coming automated aerodynamic design optimization mission. This demand can be addressed by using both in-house codes and commercial software which have the good ability ... En savoir plus

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... En savoir plus

Pressure-driven air flow is directed over the microfluidic cavity induces circulating fluid motion in the cavity. Analyte contained in the air stream is absorbed into the cavity, mixes with the nanoparticles as a result of the circulating cavity flow. Therefore, the nanoparticles ... En savoir plus

The Polymer Electrolyte Membrane fuel cell is one of the most promising green technologies for addressing portable, as well as transportation power needs. However, the science behind the fuel cell, in many regards, is still an enigma, and even more so, with the vast numbers of novel ... En savoir plus
