Simulation and Experimental Analysis of Drug Release Rates from Magnetic Nanocomposite Spheres

L. Saeeednia[1], H. Mehraein[2], F. Abedin[1], K. Cluff[2], R. Asmatulu[1]
[1]Department of Mechanical Engineering, Wichita State University, Wichita, KS, USA
[2]Department of Bioengineering, Wichita State University, Wichita, KS, USA

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this ... Read More

Mean Flow Augmented Acoustics in Rocket Systems

S. Fischbach[1]
[1]NASA Marshall Space Flight Center / Jacobs ESSSA Group, Huntsville, AL, USA

Combustion instability in solid rocket motors and liquid engines has long been a subject of concern. Recent advances in energy based modeling of combustion instabilities require accurate determination of acoustic frequencies and mode-shapes. Of particular interest is the acoustic mean ... Read More

Methods to Optimize Plasmonic Structure Integrated Single-Photon Detector Designs

M. Csete[1], G. Szekeres[1], B. Banhelyi[2], A. Szenes[1], T. Csendes[2], G. Szabo[1]
[1]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary
[2]Department of Computational Optimization, University of Szeged, Szeged, Hungary

Introduction: Predesigned plasmonic structures are capable of enhancing optical phenomena, the key concept is tailoring the integrated devices' composition to engineer the spectral response and near-field distribution [1]. Our previous studies have shown that three-quarter-wavelength ... Read More

Modeling Mechanical Property Changes During Heating of Carrot Tissue - A Microscale Approach

S. Kadam[1], A. K. Datta[1]
[1]Department of Biological & Environmental Engineering, Cornell University, Ithaca, NY, USA

Turgor pressure loss and pectin degradation result in texture loss during cooking of plant based materials. To simulate texture loss, a simultaneous heat and moisture transfer, pectin degradation in the cell wall material and solid mechanical model was developed at the microscale using ... Read More

AC Electrothermal Characterization of Doped-Si Heated Microcantilevers Using Frequency-Domain Finite Element Analysis

K. Park[1], S. Hamian[1], A. M. Gauffreau[2], T. Walsh[2]
[1]Mechanical Engineering Department, University of Utah, Salt Lake City, UT, USA
[2]Department of Mechanical, Industrial & Systems Engineering, University of Rhode Island, Kingston, RI, USA

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high ... Read More

Numerical Simulation of Thermal Runaway in a THz GaAs Photoconductor

S. Sarodia[1,2], W. Zhang[2], E. Brown[2]
[1]Centerville High School, Dayton, OH, USA
[2]Wright State University, Dayton, OH, USA

Ultrafast terahertz photoconductor devices, especially photomixers, are usually limited in output power by device failure thought to be caused by excessive temperatures. Therefore, understanding of thermal breakdown is essential to the study of device reliability and failure of ... Read More

Optimization Module Enables Hybrid Experimental-Numerical Algorithm for 3D Particle Image Velocimetry

M. Sigurdson[1], C. Meinhart[1], I. Mezic[1]
[1]Department of Mechanical Engineering, University of California - Santa Barbara, Santa Barbara, CA, USA

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... Read More

Evaluation of Novel Wing Design for UAV

P. K. Bahumanyam[1]
[1]University of Alabama in Huntsville, Huntsville, AL, USA

Viable design alternative for the existing and fast growing UAVs which are optimized for unmanned flight is of great demand. Designing of a small scale UAV alternative to the AAI Aerosonde UAV has been considered changing the wing tail configuration of the vehicle analyzing both ... Read More

Design of Precision Magnetic Fields for Fundamental Neutron Symmetries

M. Higginson-Rollins[1], C. Crawford[2]
[1]Department of Electrical & Computer Engineering, University of Kentucky, Lexington, KY, USA
[2]Department of Physics & Astronomy, University of Kentucky, Lexington, KY, USA

The traditionally magnetic design process involves guessing at a reasonable conductor geometry, using finite element analysis (FEA) software to calculate the resulting fields, and modifying the configuration iteratively to reach an acceptable solution. Taking the opposite approach, we ... Read More

Magnetorheological Fluid Based Braking System Using L-shaped Disks

M. Hajiyan[1], S. Mahmud[1], H. Abdullah[1]
[1]School of Engineering, University of Guelph, Guelph, ON, Canada

This paper presents a novel design of multi-disks Magnetorheological braking system (MR brake) for automotive application. Magnetic saturation in both electromagnetic core and MR fluid is considered in this paper. The electromagnetic analysis of the proposed configuration is carried out ... Read More
