Localization of Chemical Sources Using Stochastic Differential Equations in Realistic Environments

A. Mohammed, and A. Jeremic
McMaster University, Hamilton, L8S4K1, Canada

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 differential equations describing more complex motion mechanisms such as Brownian motion. In this paper we propose the ...

Electric Field Analysis of a Green Rust Surface Treatment Tank for High/Super Alloys

H.K. Yang[1], S.C. Tseng[1]
[1]Institute of Mechanical Engineering, National Yunlin University of Science Technology, Taiwan

In order to perform rust surface treatment for stainless wires, we proposed an electrolyzing equipment to do so. It has the following advantages: safer, cheaper and less environmental pollution. To study the performance of the electrolyzing process, numerical simulation for electric fields will be conducted by using COMSOL Multiphysics software. Taguchi methods was also used to obtain better ...

[1]Instituto Politécnico Nacional-ESIQIE, México D.F, México

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to allow the study of gas phase reactions at low (atmospheric) and high pressures (up to 20 MPa), with the ...

Coupled Hydrochemical Modeling for the Optimal Design of an In-situ Redox Experiment

P. Trinchero[1], J. Molinero[1], G. Román-Ross[1], A. Nardi[1], L.M. De Vries[1], T. Karvonen[2], P. Pitkänen[3]
[1]Amphos 21, Barcelona, Spain
[2]WaterHope, Helsinki, Finland
[3]Posiva, Eurajoki, Finland

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the Finnish spent fuel repository). A characteristic of these models lies in the need to integrate prior information, ...

Establishing Absorbed Dose Thresholds for Nonlinearities in Water Calorimetry

R.E. Tosh[1], H. Chen-Mayer[1]
[1]National Institute of Standards and Technology, Gaithersburg, MD, USA

The technique of water calorimetry for primary-standard dosimetry of radiotherapy-level ionizing radiation is well established at national metrology institutes around the world, where such a direct realization of absorbed dose establishes the basis for calibrating instruments used for dosimetry in medical settings. The typical calorimeter system uses miniature thermistor beads to measure ...

Constructing COMSOL Models of a Bacteriological Fuel Cell

R. Coker[1], J. Mansell[1]
[1]NASA - Marshall Space Flight Center, Huntsville, AL, USA

We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated by a membrane. The electrolyte is a brine appropriate for growing methanogenic bateria, though none are ...
