The APP as a Tool, A First Principles Approach

R. W. Pryor[1],
[1] Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The app discussed in this paper is based on a COMSOL Multiphysics® 1D heat transfer model that analyses the heat flow through a double pane window, with a gas chamber between the two panes, as would normally be mounted in the wall of a building, a container or a refrigerated chamber. The ... En savoir plus

Air-Water-Foam Mix Chamber for Fire Protection of Fossil Fuel Containers: Modeling and Optimization

S. Hidrobo [1], A. X. Jerves [1], A. Landazuri [1], S. D. Ballen [1],
[1] Universidad San Francisco de Quito, Quito, Ecuador

Since the industrial demand in the energetic, mining and oil & gas sectors has increased exponentially these last decades, security standards and fire protection methods are extremely important not only for the employees, but also for the infrastructure involved in production areas ...

Simulation of Neurotransmitter Sensing by Cyclic Voltammetry under Mechanical Motion of a Neural Electrode

S. Han [1], M. Polanco [2], S. Bawab [2], H. Yoon [1]
[1] Norfolk State University, Norfolk, VA, USA
[2] Old Dominion University, Norfolk, VA, USA

Neural electrodes for sensing neurotransmitters are embedded within the brain, detecting electrical signals produced by kinetic reaction of neurotransmitters in the brain. Sensing utilizes cyclic voltammetry (CV), which applies sweeping potentials to identify chemical kinetics of ... En savoir plus

COMSOL® Analysis for Duct Acoustic

M. M. Ghulam [1], E. J. Gutmark [1],
[1] Aerospace Department, University of Cincinnati, Cincinnati, OH, USA

COMSOL analysis of the acoustic modes of two different Combustion Wind Tunnel Facility’s test sections was conducted in this project. The test sections are rectangular ducts, therefore the mathematical expressions to predict the longitudinal and transverse modes inside a tube were used ... En savoir plus

Numerical Model Simulation of Impedance Based Control for RF Ablation Using Isolator Synergy Clamp

M. Etheridge [1], R. Lopusnik [1], A. Cates [1],
[1] AtriCure, Inc., Minnetonka, MN, USA

Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... En savoir plus

Nanofluidic Analyte Preconcentration Using Fluid Field-Effect Diodes

A. Eden [1], K. Scida [1], J. C. T. Eijkel [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California, Santa Barbara, CA, USA
[2] University of Twente, Enschede, Netherlands

Introduction Throughout the field of micro- and nanoscale electrokinetics, floating bipolar electrodes (BPEs) have proven to be useful in manipulating charged ionic species and biomolecules for electroanalytical studies. The growing use of integrated electronics in working towards fully ... En savoir plus

Numerical Simulation of Pool Film Boiling Heat Transfer during Quenching of Heated Cylindrical Rods

S. Ebrahim [1], F. B. Cheung [1], A. Alshayji [2],
[1] Department of Mechanical and Nuclear Engineering, Pennsylvania State University, University Park, PA, USA
[2] Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait

This research studies possible ways to mitigate failure of a nuclear reactor, in which the coolant supply to the nuclear core has been compromised, known as Loss of Coolant Accident (LOCA). One possible way to decrease the severity of the incident is to quickly quench the fuel rods in ... En savoir plus

Thermal Model and Control of Metal-Organic Chemical Vapor Deposition Process

J. L. Ebert [1], S. Ghosal [1], N. Acharya [1]
[1] SC Solutions, Inc., Sunnyvale, CA, USA

Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... En savoir plus

Silicon-Organic-Hybrid Independent Simultaneous Dual-Polarization Modulator: Device Theory and Design

Y. D'Mello [1], M. Hui [1], J. Skoric [1], M. Haines [1], A. Kirk [1], M. Andrews [1], D. Plant [1],
[1] McGill University, Montréal, QC, Canada

The Complementary Metal-Oxide-Semiconductor (CMOS) technology is a gateway to fabricating low cost electronic and photonic components to date. The Silicon-based nanophotonics platform leverages CMOS technology to fuel the effort to provide increasingly high-speed and high-bandwidth ... En savoir plus

Numerical Analysis and Optimization of a Multi-Mode Interference Based Polarization Beam Splitter

Y. D'Mello [1], E. Elfiky [1], J. Skoric [1], D. Patel [1], D. Plant [1]
[1] McGill University, Montréal, QC, Canada

The progression toward smaller and faster photonic circuits has led to the development of nanophotonic platforms capable of compacting many devices onto an integrated chip. These devices, as well as the input and output grating couplers, are sometimes polarization dependent, which allows ... En savoir plus
