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 ... En savoir plus

Modeling of Noise Produced by Offshore Wind Turbines with Different Foundations and Effects on the Marine Environment

B. Marmo [1], I. Roberts [1]
[1]Xi Engineering Consultants, Edinburgh, Scotland, UK

Vibration produced by offshore wind turbines during their normal operation transmits through the tower into the foundation where it interacts with the surrounding water and is released as noise. The noise produced by offshore wind turbines can be detected by fish and marine mammals and ... En savoir plus

Finite Element Analysis of Integrated Circuit Interconnect Lines on Lossy Silicon Substrate

S. Musa[1], M. Sadiku[1], and A. Emam[2]

[1]Roy G. Perry College of Engineering, Prairie View A&M University, Prairie View, TX
[2]Information Systems Department, King Saud University, Riyadh, Saudi Arabia

The silicon substrate has a significant effect on the inductance parameter of a lossy interconnect line on an integrated circuit. It is essential to take this into account in determining the transmission line electrical parameters. In this paper, a new quasi-TEM capacitance and ... En savoir plus

Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording

J. Bennington[1]
[1]Queen's University Belfast, Belfast, Northern Ireland, UK

A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... En savoir plus

Calculating Power Loss of Contactless Power Transmission Systems with Ferrite Components

S. Hanf[1] and D. Kürschner[1]
[1]Institut für Automation und Kommunikation Magdeburg, Magdeburg, Germany

In this paper a methodology for calculating loss within contactless inductive power transmission systems, resulting from hysteresis and eddy current effects, is presented. The usage of the mathematical models of Stoll and Steinmetz for the determination of core loss with COMSOL is ... En savoir plus

Modeling of Lightning Direct Effects - Interaction of Continuing Current with Aluminum Skins

Y. Kostogorova-Beller[1], and R. Collins[2]
[1]National Institute for Aviation Research, Wichita, KS, USA
[2]Hawker Beechcraft Corporation, Wichita, KS, USA

An interaction of aluminum aircraft skins with a laboratory-simulated, low-level, long-duration, continuing current representative of a natural lightning flash was modeled with COMSOL Multiphysics. For the analysis of the lightning direct effects on aircraft, the external environment is ... En savoir plus

Thermal Analysis Of A Sealed Battery Power System Enclosure For Underwater Operations

C. H. King Joel [1]
[1] Temasek Polytechnic, Singapore

COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... En savoir plus

Modeling of Grounding Systems Considering the Soil Ionization Effect Using COMSOL Multiphysics® Software

R. A. Coelho[1], H. A. D. Almaguer[1]
[1]Universidade Regional de Blumenau - FURB, Blumenau, SC, Brazil

The soil ionization is an important phenomenon to be considered in the analysis of grounding electric systems. In this way, this work has proposed a procedure that allows modeling grounding systems with COMSOL Multiphysics and MATLAB® taking into account the soil ionization effects ... En savoir plus

An Investigation of Loudspeaker Simulation Efficiency and Accuracy Using i) A Conventional Model, ii) The Near-To-Far-Field Transformation and iii) The Rayleigh Integral

R. Christensen[1], U. Skov[1]
[1] iCapture ApS, Roskilde, Denmark

Simulation on loudspeaker drivers require a conventional fully coupled vibro-acoustic model to capture all effect. An accurate vibroacoustic model can be time-consuming to solve, especially in 3D. In practical applications, this results in poor efficiency concerning the decision-making ... En savoir plus

The Influence of Core Shape and Material Nonlinearities to Corner Losses of Inductive Element

M. Puskarczyk[1], B. Jamieson[1], W. Jurczak[1]
[1]ABB Corporate Research Center, Kraków, Poland

The effects of sharp corners on the flux distribution in a ferromagnetic core are modeled using COMSOL Multiphysics® to determine the time-domain flux density for an applied field which is uniform in the non-corner section of the core. The frequency spectrum of the flux distribution is ... En savoir plus
