A Study of the Effects of Mounting Supports, and Dissipation on a Piezoelectric Quartz Double-Ended Tuning Fork Gyroscope

G. Choi[1], Y. Yong[1]
[1]Rutgers University, New Brunswick, NJ, USA

A COMSOL model of a piezoelectric quartz double ended tuning fork gyroscope was implemented. The gyroscope has two detection modes; the first mode detects the angular velocity about a z-axis perpendicular to the tuning fork plane (x-y plane), while the second mode detects the angular ...

Application of the Hot Wire Technique and COMSOL Multiphysics for Heat Transfer Monitoring in Solids

J. Hernandez[1], V. Suarez[1], J.A. Calderon[1], E. Marin[1], B. Rojas[1], A.G. Juarez[1], J. Guarachi[1]
[1]Centro de Investigación en Ciencia Aplicada y Tecnología Avanzada Unidad Legaria del Instituto Politécnico Nacional, Mexico, Distrito Federal, Mexico

We applied the Hot Wire (HW) technique and COMSOL Multiphysics software to study the heat transfer of a homogeneous and isotropic solid material. The HW technique is based on the application of a linear power density modulated by a rectangular pulse of heat, in a specific time period. ... Per saperne di più

Post Harvest Cold Chain Optimization of Little Fruits

S. Marai[1], E. Ferrari[1], R. Civelli[1]
[1]DiSAA, University of Milan, Milan, Italy

This paper presents heat transfer 3-D models of a passive refrigeration system used to improve the shelf life and the quality of the perishable fruits. Passive refrigerator system uses the changing phase to keep temperature close to the melting temperature. A multi-step study was ... Per saperne di più

3D Simulations of an Injection Test Done Into an Unsaturated Porous and Fractured Limestone

A. Thoraval[1], Y. Guglielmi[2], F. Cappa[3]
[1]INERIS, Nancy, France
[2]CEREGE, Aix-en-Provence, France
[3]GEOAZUR, Valbonne, France

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP ... Per saperne di più

Polymer Nanowire based Impedance Biosensor

N. Das[1], C. R. Chaudhuri[1]
[1]Department of Electronics and Telecommunication, BESUS, Howrah, West Bengal, India

In this paper, we have proposed an impedance biosensor based on polymer nanowire (made of polyaniline) for efficient electric field mediated capture of biomolecules. Existing polymer nanowire based biosensors fail to achieve high sensitivity for low surface to volume ratio as the whole ... Per saperne di più

COMSOL Aided Design of an Extraction Pipe for the Electron Beam from a Plasma Focus Device

M. Valentinuzzi[1], E. Ceccolini[1], D. Mostacci[1], M. Sumini[1], F. Rocchi[2]
[1]Montecuccolino Nuclear Engineering Laboratory, University of Bologna, Bologna, Italy
[2]UTFISSM-PRONOC, ENEA, Bologna, Italy

The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless ... Per saperne di più

Piezoelectric Transducers and Ultrasound Imaging: Impact of Materials Properties and Multiphysics Aided Design


Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in ... Per saperne di più

A Study on the Suitability of Indium Nitride for THz Plasmonics

A. Shetty[1], K. J. Vinoy[1], S. B. Krupanidhi[2]
[1]Electrical Communication Engineering, Indian Institute of Science, Bangalore, India
[2]Materials Research Centre, Indian Institute of Science, Bangalore, India

As interest in the electromagnetic spectrum expands towards the infrared and terahertz range, the distinct advantages of using semiconductors instead of metals for plasmonic applications must be understood. Plasmonic resonances in gold (Au) and indium nitride (InN) gratings are studied, ... Per saperne di più

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Per saperne di più
