[4]Instituto de Energías Renovables, Universidad Nacional Autónoma de México, Temixco, Morelos, México

Flows of electrically conducting liquids in external magnetic fields are present in several applications. In this kind of flow, the inhomogeneous magnetic field creates a breaking force on the conducting fluid. As a result, a stagnant zone is formed in the zone affected by the localized ... Read More

Optimizing Inductor Winding Geometry for Lowest DC-Resistance using COMSOL Multiphysics® with LiveLink™ for MATLAB®

H. Schneider[1], T. Andersen[1], J. D. Mønster[1], M. P. Madsen[1], A. Knott[1], M. A. E. Andersen[1]
[1]Technical University of Denmark, Lyngby, Denmark

An optimization routine is presented to optimize a hybrid winding geometry for a toroid inductor in terms of the DC-resistance. The hybrid winding geometry consist of bended foil pieces connected through traces in a PCB. MATLAB® is used to create a GUI that visually plots the winding ... Read More

Comparing Isotropic and Anisotropic Brain Conductivity Modeling: Planning Optimal Depth-Electrode Placement in White Matter for Direct Stimulation Therapy in an Epileptic Circuit

[3]Rush University Medical Center, Chicago, IL, USA

The goal of our work was to calculate a patient-specific brain conductivity map for predicting the extent to which direct stimulation therapy can strategically propagate through pathological white matter. Our laboratory developed isotropic and anisotropic human brain finite element ... Read More

Investigation of a Hybrid Winding Concept for Toroidal Inductors Using 3D Finite Element Modeling

H. Schneider[1], T. Andersen[1], J. D. Mønster[1], M. P. Madsen[1], A. Knott[1], M. A. E. Andersen[1]
[1]Technical University of Denmark, Lyngby, Denmark

This paper investigates a hybrid winding concept for a toroidal inductor by simulating the winding resistance as a function of frequency. The problem of predicting the resistance of a non-uniform and complex winding shape is solved using 3D Finite Element Modeling. A prototype is built ... Read More

Modeling Magnetic Induction from Transient Events Impinging upon a Conducting Moon

Finite Element Analysis of Defibrillation Current Density in Pregnant Women

A. Jeremic[1], E. Khosrowshahli[1]
[1]McMaster University, Hamilton, ON, Canada

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a ... Read More

Electrophoretic Focusing and Navigation for Intranasal Target Drug Delivery

X. Si[1]
[1]Calvin College, Grand Rapids, MI, USA

Direct nose-to-brain drug delivery circumvents the blood-brain-barrier and has multiple advantages over intravenous delivery. However, its application is limited by the extremely low delivery efficiency to the olfactory region. This study evaluated the feasibility of targeted drug ... Read More
