Magnetic Ratchet

A. Auge, F. Wittbracht, A. Weddemann, and A. Hütten
Department of Physics, University of Bielefeld, Germany

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... En savoir plus

Design and Simulation of a MEMS-Based Ultrasonic Transducer for Viscosity Sensing Applications

Rahul Goyal [1], Divya Mohan Yadav [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... En savoir plus

Simulation of Convection in Water Phantom Induced by Periodic Radiation Heating

H.H. Chen-Mayer[1], and R. Tosh[1]
[1]Ionizing Radiation Division, National Institute of Standards and Technology, Gaithersburg, Maryland, USA

Water calorimetry is employed to establish a primary reference standard for radiation dosimetry by measuring the temperature rises in a water phantom (a cube of about 30 cm x 30 cm x 30 cm) subjected to a beam of ionizing radiation. We use COMSOL Multiphysics to model the system using ... En savoir plus

The Birefringence Change of Optical Fiber Polarizer with Fe-C Film in Corrosive Solution

胡文彬 [1], 丁立康 [1], 朱诚 [1], 袁银权 [1],
[1] 武汉理工大学光纤传感国家工程实验室

The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... En savoir plus

Estimation of Boundary Properties Using Stochastic Differential Equations and COMSOL

A. Atalla[1], and A. Jeremic[1]
[1]McMaster University, Hamilton, Ontario, Canada

The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, ... En savoir plus

Model of an Interdigitated Microsensor to Detect and Quantify Cells Flowing in a Test Chamber

E. Bianchi[1], F. Boschetti[1], G. Dubini[1], and C. Guiducci[2]
[1]Politecnico di Milano, LABS, Laboratory of Biological Structure Mechanics, Structural Engineering Department, MI, Italy
[2]CLSE - Swiss Up Chair -Laboratory of Life Science Electronics, EPFL, Losanna, Swissland

Microfabricated planar interdigitated electrodes can detect and analyze cells or particles giving an impedance-based characterization. This method presents several advantages: real-time detection, label-free analysis, non-invasive sensing, easiness of integration and high-throughput ... En savoir plus

A Multidisciplinary Approach Towards Low Radar Cross-section Air Intake Duct Design

Dr. Balamati Choudhury [1], Sandeep [1], Shibu P. S. [1], Madhuri S. [1], R U Nair [1],
[1] CSIR - National Aerospace Laboratories, Bangalore, Karnataka, India

Stealth technology is one of the important requirements for the next generation (5th Generation) combat aircraft. Most of the stealth aircraft design focuses on low radar signature to reduce the detection possibility. Stealth technology allow the aircraft to enter the enemy territory ... En savoir plus

Development of Electrochemical Methods for Differentiation of the Catecholamine Neurotransmitters

I. Fritsch [1], M. Abrego Tello [1],
[1] University of Arkansas, Fayetteville, AR, USA

Neurological disorders afflict tens of millions in the US. We are developing technology to advance capabilities for monitoring the neurotransmitters, dopamine, norepinephrine, and epinephrine (the catecholamines), to facilitate direct observations of their mutual interactions in brain ...

Simulation of Laser-Excited Surface Acoustic Waves Travelling on a Steel Hemisphere Shell

J. Mäkinen [1], D. Veira Canle [1], R. Blomqvist [1], A. Salmi [1], E. Hæggström [1],
[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

Non-contacting guided wave tomography based on laser ultrasonic waves can be used to inspect structures that are inaccessible to traditional ultrasound methods. Such structures could be, chemically or physically hard to reach, e.g. hot metal structures, metal implants inside tissue or ... En savoir plus

COMSOL in the Academic Environment at USNA

K. Mcilhany[1], and R. Malek-Madani[2]
[1]Department of Physics U. S. Naval Academy, Annapolis, Maryland, USA
[2]Department of Mathematics, U. S. Naval Academy, Annapolis, Maryland, USA

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... En savoir plus
