Modeling the Collimator-Detector Scattering Using Stochastic Differential Equations and COMSOL

A. Jeremic[1], T. Farncombe[2], S. Liu[2], and Y. Abdul-Rehman[1]
[1]Department of Electrical and Computer Engineering, McMaster University, Hamilton, Ontario, Canada
[2]Department of Radiology, McMaster University, Hamilton, Ontario, Canada

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular ... Read More

Optimization of a Thermal Actuator for Low Power/Low Cost Applications

R. Zúñiga-Quesada[1], M. Vílchez-Monge[1], P. Vega-Castillo[1]
[1]Instituto Tecnológico de Costa Rica, Cartago, Costa Rica

This work describes the study of a thermal actuator and modifications to the materials employed in order to decrease power consumption and implementation costs. For this study, we worked on improving the thermal actuator described in the work of T. Ebefors. The criteria for choosing the ... Read More

Wireless Interaction of Neighboring Two Arm Archimedes Spiral Coils in the RF Electromagnet Range

A. Kalinowski[1]
[1]Naval Undersea Warfare Center/ Division Newport, Newport, RI, USA

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the  ... Read More

Control of Preheating Process of Casting Die as Distributed Parameter System

C. Belavý[1], G. Hulkó[1], K. Ondrejkovic[1], and P. Zajícek[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper distributed parameter system models in the form of lumped-input/distributed-output systems are introduced and modeling of temperature fields of the die in the benchmark casting plant is presented. Temperature fields were modeled and studied using a finite element method ... Read More

Reliability Evaluation for Static Chamber Method at Landfill Sites

H. Ishimori[1], K. Endo[1], and M. Yamada[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and ... Read More

Designing B-field Coils from the Inside-Out

C.B. Crawford[1], Y. Shin[1], and G. Porter[1]
[1]Department of Physics and Astronomy, University of Kentucky, Lexington, Kentucky, USA

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor / magnetic material configuration, using FEA software to calculate the resulting field, modifying the configuration, and iterating to produce the desired field. Our method involved solving the ... Read More

Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations

D. Homentcovschi[1], and R.N. Miles[1]
[1]Department of Mechanical Engineering, SUNY Binghamton, NY

This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure ... Read More

Effect of S-p Relation Model on DNAPL Migration Simulation Result

H. Ishimori[1], and K. Endo[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models ... Read More

Design Simulations of a General Purpose Research Micro Reactor for Methane Conversion to Syngas.

C. Bouchot[1], and M.A. Valenzuela[1]
[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 ... Read More
