A Mixed Boundary Value Problem That Arises in the Study of Adhesively Bonded Structures

R. Malek-Madani, and J.J. Radice
US Naval Academy, Annapolis, MD, USA

The study of deformation of an adhesively bonded sandwich structure reduces to solving the biharmonic equation for the Airy Stress subject to mixed boundary conditions. Because of the nature of the boundary conditions, this boundary value problem does not yield to the standard elementary ... Read More

Solving Two-scale Transport Laws During Frying of Foods Using COMSOL Multiphysics

J. Maneerote, and P.S. Takhar
International Center for Food Industry Excellence Texas Tech University, Lubbock, TX, USA

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based ... Read More

Finite Element Modeling of the Stress Field in a Cell-Seeded Microchannel

G. Zhu, and Y. Li
Lawrence Technological University, Southfield, MI, USA

Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic ... Read More

Finite Element Modeling of Electromagnetic Scattering for Microwave Breast Cancer Detection

R. Firoozabadi[1], and E.L. Miller[2]
[1]Airvana Inc., Chelmsford, MA, USA
[2]Tufts University, Medford, MA, USA

In this paper, COMSOL Multiphysics software is utilized as a finite element forward solver to obtain the electromagnetic fields at the receiving antennas while the breast is illuminated by one antenna in the array. Geometry consists of coronal slices of the 3-D breast. Simulations are ... Read More

Numerical Investigation of a Time-dependent Magnetic Actuation Technique for Tagging Biomolecules with Magnetic Nanoparticles in a Microfluidic System

A. Munir, J. Wang, Z. Zhu, and H.S. Zhou
Worcester Polytechnic Institute, Worcester, MA, USA

The magnetic body forces that act on mono-dispersed magnetic nanoparticles (MNPs) tagged biomolecules in a microfluidic system can be efficiently used in various applications that involve separation and detection including DNA and protein analysis, bio-defense, drug delivery, and ... Read More

Control Synthesis for Distributed Parameter Systems Modeled by FEM in COMSOL Multiphysics

C. Belavý, G. Hulkó, P. Buček, and S. Lel'o
Slovak University of Technology in Bratislava, Bratislava, Slovakia

Technological processes in the engineering practice from point of view of systems and control theory are frequently in the form of distributed parameter systems (DPS). Techniques of FEM based modeling and design of control synthesis methods of DPS which is acceptable for various ... Read More

Finite Element Modeling of a Cell Lysing Chip

S. Maloney[1,2], Y. Li[1,2], G. Auner[1], and J. Smolinski[1]
[1]Wayne State University, Detroit, MI, USA
[2]Lawrence Technological University, Southfield, MI, USA

We are working on a microfabricated lysing chip that uses a piezoelectric actuator to provide ultrasonic energy to break apart cells. The device contains pillars with varying dimensions. We hypothesize that increasing the aspect ratio of pillars will increase the efficiency of the ... Read More

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 ... Read More

Modeling Bacterial Clearance Using Stochastic-Differential Equations

A. Jeremic, and A. Atalla
McMaster University, Hamilton, ON, Canada

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By ... Read More

Beam Structure As an Acoustic Wave Sensor: A Study of the Effect of Sensor Design on Its Sensitivity to Noise

F. Akasheh[1], A. Biddle[1], W.S. Shepard Jr.[2], and B.B.B. Zhang[2]
[1]Tuskegee University, Tuskegee, AL, USA
[2]University of Alabama, Tuscaloosa, AL, USA

The detection and identification of the location of a sound source is commonly done using arrays of microphones. A recent new alternative approach has been proposed which involves the use of continuous structures, such as beams or plates, as acoustic wave sensors. The sound wave ... Read More
