Localization of Chemical Sources Using Stochastic Differential Equations in Realistic Environments
Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic ... Read More
A Model of a Horizontal Atmospheric Pressure Chemical Vapor Deposition Reactor
A model of a horizontal atmospheric pressure chemical vapor deposition reactor was implemented to aid in the design of a laboratory based one. The model coupled momentum transport, energy transport, and mass transport phenomena to account for reacting fluid flow of a compressible gas in ... Read More
Multiphysics Modeling of an Ion Mobility Spectrometer
In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field." The production of the ... Read More
Computational Analysis of the Mechanical and Thermal Stresses in a Thin Film PProDOT-Based Redox Capacitor
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 ... Read More
AC/DC Modeling and Experimental Impedance Verification of 3D MEMS Inductor Coils
In this work, an analysis is presented for a 3-dimensional RF MEMS coil using the COMSOL AC/DC module in conjunction with the CAD import module. The realization of being able to produce such 3-dimensional RF coils allows for less surface area to be needed for similar inductor performance ... Read More
Modeling Joule Heating Effect on Lunar O2 Generation via Electrolytic Reduction
Kennedy Space Center is leading research work on lunar O2 generation via electrolytic reduction of regolith. The metal oxide present in regolith is dissociated into oxygen anions and metal cations leading to the generation of gaseous oxygen at the anode and liquid metal at the cathode. ... Read More
Temperature Excursions at the Pulp-Dentin Junction during the Curing of Light-Activated Dental Restorations
Heat produced during the curing of light-activated dental restorations could damage the dental pulp. Given the prevalence of composite restorations and the importance of avoiding injury to the pulp, efforts should be made to minimize the temperature increase that occurs at the pulp ... Read More
Magnetic Particle Buildup Growth on Single Wire in High Gradient Magnetic Separation
Magnetic fluids containing nano or submicron magnetic particles and their application in food, biological and pharmaceutical systems have recently attracted increasing attention. Magnetic particles can be collected efficiently in magnetizable matrices (e.g. iron wires) in high gradient ... Read More
