Calculating Iron Losses Taking into Account Effects of Manufacturing Processes

P. Goes, E. Hoferlin, and M. De Wulf
OCAS N.V. – ArcelorMittal Research Gent, Belgium

Finite element modelling of electrical machines usually assumes uniform magnetic properties and loss behaviour throughout the steel laminations. It is well known that manufacturing processes, like the assembly of the machine, deteriorate the properties of the core material. Generally, ... Read More

Optical Trapping on Waveguides

O.G. Hellesø [1],
[1] University of Tromsø, Tromsø, Norway

On the surface of an optical waveguide, there is an evanescent field. The evanescent field decays fast and this steep gradient can be used to pull nano- and microparticles down towards the waveguide surface. Radiation forces will propel the particle forward along the waveguide. Trapping ... Read More

Decomposition of Fundamental Lamb Wave Modes in Complex Metal Structures Using COMSOL Multiphysics®

M. Harb [1], R. Malaeb [1], E. Mahfoud [1],
[1] Department of Mechanical Engineering, American University of Beirut, Libanon

Structural Health Monitoring Systems are being highly investigated to evaluate the health of a structure and detect any damages occurring in real time. Such systems require intensive data analysis which gets even more intricate when working with complex structures due to undesirable ... Read More

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Read More

Photoacoustic Modeling Using Amplitude Mode Expansion Method in a Multi-Scale T-cell Resonator

S. El-Busaidy [1], B. Baumann [1], M. Wolff [1], L. Duggen [2],
[1] Hamburg University of Applied Sciences, Germany
[2] University of Southern Denmark, Denmark

The photoacoustic (PA) effect consisting of the generation of an acoustic signal based on the absorption of light has already demonstrated its potential for various spectroscopic applications for both gaseous and solid samples. The signal produced during photoacoustic spectroscopy (PAS) ... Read More

Multiphysics Simulation of Isoelectric Point Separation of Proteins Using Non-Gel Microfluidic System

A. Contractor[1], N. Xue[2], J.B.Lee[2], A. Balasubramanian[1], and G. Hughes[1]
[1]Lynntech, Inc., College Station, Texas, USA
[2]Micro Nano Devices and Systems (MiNDS) Laboratory, Department of Electrical Engineering, University of Texas at Dallas, Texas, USA

A portable device that can identify protein and peptides real time in complex biological systems such as human bodily fluids reliably and accurately is in high demand to properly diagnose and treat medical conditions. Lynntech has developed an innovative Polydimethylsiloxane (PDMS) based ... Read More

Design of Next Generation Mid-infrared Fiber Optics

X. Ji [1], R. Page [2], V. Gopalan [1],
[1] Pennsylvania State University, State College, PA, USA
[2] Pacific Lutheran University, Tacoma, WA, USA

Optical fibers that can deliver mid-infrared light in a wide wavelength range are in high demand due to their significant potentials in sensors, chemical imaging, optoelectronics and nonlinear optics applications. Semiconductors such as Ge, ZnSe and Si are good infrared-transparent ... Read More

Evaluation of Binary Mixture Models for 3D Printed Biosensors

J. Persad [1], S. Rocke [1], D. Ringis [1], A. Abdool [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies [1]. The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. ... Read More

Plasmon Enhanced Fluorescence Characteristics Government by Selecting the Right Objective Function
