Dynamic Deformation of Soft Particle in Dual-trap Optical Tweezers

Y. Sheng[1], S. Rancourt-Grenier[1], P. Bareil[1], P. Duval[1], M. Wei[2], A. Chiou[2], and J. Bai
[1]University Laval, Quebec, QC, Canada
[2]National Yang-Ming University, Taipei, Taiwan

A dual-trap optical tweezers is used for deforming the red blood cell (RBC) in suspension and studying its elasticity. The 3D deformation of the cells was computed with the elastic membrane theory. The calculated deformation can fit to experimental data resulting in cell’s elasticity ... Read More

Prediction of Time of Death Using a Heat Transport Model

J.L. Smart[1], and M. Kaliszan[2]
[1]University of Kentucky, Paducah, KY, USA
[2]Medical University of Gdansk, Gdansk, Poland

COMSOL Multiphysics® 4.0 was used to study conductive and convective heat transfer from the human eyeball to the surrounding air. Postmortem temperature decay curves were collected in eyeballs of numerous human corpses. Of course, these curves represent only a portion of the complete ... Read More

COMSOL Assisted Simulation of Laser Engraving

H. Karbasi
Conestoga College, Kitchener, ON, Canada

The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser beam ... Read More

Drift-Diffusion and Ballistic Transport Modeling in III-Nitride Multiple-QW Light Emitting Structures

M.V. Kisin, and H.S. El-Ghoroury
Ostendo Technologies Inc., Carlsbad, CA, USA

COMSOL-based modeling software developed at Ostendo Technologies allows detailed simulation of semiconductor lasers and light-emitting diodes. In this work, we study the inhomogeneity of the carrier injection into optically active quantum wells of polar and nonpolar III-nitride light ... Read More

Thermally Induced-Noise Reduction Using an Electrostatic Force Feedback

H. Lee, and J.V. Clark
Purdue University, West Lafayette, IN, USA

In this paper we present a method to mitigate the effect of thermally-induced noise in Micro-Electro-Mechanical Systems (MEMS) through a force feedback circuit. Inherent noise-induced vibrations, which would be inconsiderable in macro scale, are considered as a limitation in micro- and ... Read More

Modeling and Simulation of a Piezoelectric Micro-Power Generator

E. Abdel-Rahman, M. Pallapa, M.A.S. Aly, L. Wong, A.I.H. Chen, K.W. Wong, and J.T. Yeow
University of Waterloo, Waterloo, ON, Canada

Micro-power generators (MPGs) harvest and store small amounts of ambient energy. The motivation of this paper is to compare the MPG modeling and simulation results obtained from COMSOL Multiphysics® with those obtained using three other approaches: CoventorWare®, ANSYS® and ... Read More

$Modeling Light Diffraction Using the Finite Element COMSOL$

Modeling Light Diffraction Using the Finite Element COMSOL

J.D. Bamonte
U.S. Naval Academy, Annapolis, MD, USA

COMSOL is finite element modeling software capable of solving partial differential equations. This capability allows for the modeling of boundary value problems, which is necessary to the study of light and the properties of light propagation. For this study, we are modeling Fraunhofer ...

Microsoft Technical Computing - The Advancement of Parallelism

T. Quinn
Microsoft, USA

Tom Quinn works as a Partner Business Development Manager for Microsoft as part of its HPC team working together with ISV, OEM and SI partners, in the HPC marketplace. Before joining Microsoft, Mr. Quinn worked as the Director of Government Business Development for Linux Networx, a small ... Read More

Virtual Acoustic Prototyping – Practical Applications for Loudspeaker Development

A. Salvatti
JBL Professional, Northridge, CA, USA

The author presents an overview of methods to build virtual prototypes of both horns and loudspeaker drivers which allows a significant reduction in the number of physical prototypes, as well as reduced development time. This paper will present some of the practical results from work the ... Read More

Modeling of an Optical Black Hole with True Gaussian Beam Incidence

X. Ni[1], A. Kildishev[1], E. Narimanov[1], and L. Prokopeva[2]
[1]Purdue University, West Lafayette, IN, USA
[2]Russian Academy of Sciences, Novosibirsk, Russia

We model an ideal optical black hole device in COMSOL Multiphysics as an electromagnetic scattering problem. The device is illuminated with a Gaussian beam which is focused at a fixed position in horizontal direction (x0) and different positions in vertical direction (y0). The device is ... Read More
