[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 ... 詳細を見る

A Study of Curved Flexures for MEMS

Minhee Jun[1], and Jason V. Clark[1]
[1]Departments of Electrical and Computer Engineering, Purdue University, West Lafayette, IN, USA

Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness ... 詳細を見る

Multiphysical Modeling of Calcium Carbonate Transportation in UV Disinfection in Water Treatment

E. R. Blatchley[1], and B.Z. Sun[1]
[1]Department of Civil Engineering, Purdue University, West Lafayette, IN, USA

Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic ... 詳細を見る

Two-dimensional Analysis of Triple Coupled Physics of Structural Mechanics, Diffusion and Heat Transfer in a Gas Pipe

P. Lee-Sullivan[1], and M. Haghighi-Yazdi[1]
[1]Department of Mechanical and Mechatronics Engineering, University of Waterloo, Waterloo, Ontario, Canada

In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary ... 詳細を見る

Magneto-hydrodynamic Flow in Electrolyte Solutions

M. Qin[1], and H. Bau[1]
[1]Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania, Pennsylvania, USA

The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides ... 詳細を見る
