Fibre-Optic Microsensor Based on Surface Plasmon Resonance in a Microfluidic Cell : An Experimental and Numerical Multiphysics Approach

G. Louarn, T. Makiabadi, V. Le Nader, and M. Kanso
Institut des Matériaux Jean-Rouxel (IMN), CNRS- Université de Nantes, France

In the last decade, the surface plasmon resonance (SPR) has become a very sensitive technique for real-time detection in many application areas. Considering the fiber optic concept and the important needs for analyzing biomolecular reactions through automated and miniaturized components, ... En savoir plus

Simulation Based Approach to Fluorescence Diffuse Optical Tomography

R. Singh, and I. Jose
BITS Pilani Goa Campus
Goa, India

Diffuse Optical Tomography (DOT) uses Near Infra-red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such applications where high ... En savoir plus

Development of Mathematical Model for Determining Sound Reduction Index of Building Elements

J. Ratnieks, A. Jakovics, and J. Klavins
University of Latvia
Riga, Latvia

Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is ... En savoir plus

Numerical Simulations of a Subsonic/Supersonic Coaxial Jet for an Efficient Design of Experimental Setup

D. Guariglia[1], C. Schram[1]
[1]von Karman Institute for Fluid Dynamics, Sint-Genesius-Rode, Belgium

The flow field of a coaxial jet with the internal (primary) flow being subsonic and the external (secondary) flow being supersonic has been investigated with COMSOL Multiphysics® software. We used the results to correct defects in the nozzle geometry and we evaluated the effect of heat ... En savoir plus
