A pocket-size portable particle size detector for diesel and cigarette smoke aerosols is being designed using particle size and composition methods. Aerodynamics, fluid properties, material composition and aerosol composition are taken into account. Testing methods for the design include using an impactor and virtual impactor with two quartz crystal resonators to determine particle composition ...

Computational models of biological systems are becoming more and more common in medical research areas. Evidence of this can be found by examining the number of articles containing the term “finite element” in the expansive National Institutes of Health (NIH) digital research archive PubMed. Numerical modeling of biological systems allows the execution of “computational ...

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...

Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like electroactive polymers (EAPs) or metal oxides. This work investigates the stresses and heat flux of the electrode ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

Modern electronic assemblies and printed circuit boards (PCB) with their sensitive structures and elements have to be protected against environmental influences by conformal coating or casting compounds. In this case the main challenge is the simultaneous curing of the polymers and the safekeeping of the electronic elements and structures on the PCB. This implies the investigation of the heating ...

The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar and turbulent regimes has been considered. In the turbulent regime the RANS model with default parameter ...

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental evaluations of the detection principle and are in the stage of optimization of several parts of the system. As ...
