Quench Propagation and Detection in a YBCO Racetrack

G. Escamez[1], C. Lorin[1], T. Wu[1], P. J. Masson[1]
[1]University of Houston, Houston, TX, USA

High temperature superconductors (HTS) such as YBCO coated conductors show great promise for future applications where high magnetic fields are needed. The superconducting state only exists under a critical surface defined in the (J,T,B) space. Quench is the process by which a current ... Mehr lesen

Modeling 3D Calcium Waves from Stochastic Calcium Sparks in a Sarcomere Using COMSOL Multiphysics®

L. T. Izu[1], Z. Coulibaly[2], B. Peercy[2]
[1]University of California-Davis, Davis, CA, USA
[2]University of Maryland, Catonsville, MD, USA

This paper utilizes the COMSOL Multiphysics® general form PDE interface and MATLAB® to model stochastic calcium waves in a sarcomere (basic unit of a heart cell). The model we present here shows the evolution of waves generated from calcium being released stochastically from sites ... Mehr lesen

Numerical Study of the Controlled Droplet Breakup by Static Electric Fields inside a Microfluidic Flow-focusing Device

Y. Li[1], K. Nandakumar[1], M. Jain[1]
[1]Louisiana State Univeristy, Baton Rouge, LA, USA

Conventional passive microfluidic flow-focusing devices confront difficulties in controlling droplet sizes in dripping regime especially when the dispersed phase has a large viscosity. It is reported that external electric field can be used to manipulate the droplet breakup. In the ... Mehr lesen

Modeling of an Oxygenation-Aided 3D Culture for Functional Beta-Cell Expansion

S. Jin[1], J. McReynolds[1], X. Li[2], J. Guan[2]
[1]Department of Biomedical Engineering, College of Engineering, University of Arkansas, Fayetteville, AR, USA
[2]Department of Materials Science and Engineering, The Ohio State University, Columbus, OH, USA

Currently, researchers are looking for ways to mass-produce biologically functional pancreatic beta cells in vitro because of the shortage of donor tissue needed for diabetes cell therapy. The beta cells will become hypoxic if their high oxygen demands are not met. We hypothesized that ... Mehr lesen

Development of a New Blade Profile for a Vertical Axis Wind Turbine

S. Yoshioka[1]
[1]Ritsumeikan University, Shiga, Japan

The vertical axis wind turbine design depicted in (Fig.1) is widely considered a wind turbine of a wind power generation system because it can be easily miniaturized, it generates low noise, and it rotates regardless of wind direction. The vertical axis wind turbine has, however, low ... Mehr lesen

Modeling Light Propagation in Skin for Visualization of Subcutaneous Veins

H. Kwon[1], R. Huancaya[1]
[1]Andrews University, Berrien Springs, MI, USA

Vein visualization systems such as the VeinViewer are vein-contrast enhancement devices that use an infrared camera to highlight blood or the underlying vasculature and project the image in real time onto the skin. Understanding the light propagation in a realistic skin model is ... Mehr lesen

Simulation of Transdermal Toxin Expulsion via Adsorptive Dermal Patch using COMSOL Multiphysics®

H. Kwon[1], M. Hess II[1], R. M. Polski
[1]Andrews University, Berrien Springs, MI, USA

Mathematical skin models play an important role in fields such as transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been conducted on modeling skin for transdermal drug delivery; however, little effort has been made to view the ... Mehr lesen

Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... Mehr lesen

Designing and Simulating THz Guided Wave Devices Using Finite Element Techniques

L. M. Hayden[1], D. A. Sweigart[1]
[1]Department of Physics, University of Maryland Baltimore County, Baltimore, MD, USA

The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. ... Mehr lesen

Why We Have Earthquakes in the Eastern United States

J. K. Costain[1]
[1]Virginia Tech, Blacksburg, VA, USA

There are only two types of naturally-occurring earthquakes anywhere on the Earth: 1) those associated with the dynamics of plate tectonics and 2) those associated with the dynamics of the hydrologic cycle. The first type is characteristic of an INTERplate setting (like the San Andreas ... Mehr lesen
