The modeling of light propagation through multiple layers of biological tissue are assessed & compared to the theoretical predictions by Perelman at al. [94 & 95] of the most-favorable-path (MFP). The MFP on which photons will be found can be obtained from the path of the net ... En savoir plus
In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... En savoir plus
Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low ... En savoir plus
We are developing a solid state gas sensor that combines a small form factor with the high sensitivity of optical gas detection. The gas sensor is based on an optical resonant microsystem that is penetrated by gas molecules. This microsystem consists of an array of vertical rods in air ... En savoir plus
Adaptive Optics units are mounted on many large telescopes, thus enabling diffraction-limited astronomical images through compensation of the effects of atmospheric turbulence. The design of the control system of the Deformable Mirror includes a feed-forward block, aimed for increasing ... En savoir plus
William T. Vetterling, Ph.D., is a Research Fellow of ZINK Imaging, Inc. and manager of its Image Science Laboratory in Bedford, Massachusetts. He received his Ph.D. in condensed-matter physics from Harvard University, and joined the Harvard faculty in 1976. In 1984 he began working with ... En savoir plus
Design and manufacture of thrusters for producing very low thrust force in the range of milli or micro newtons using micronozzles has been actively developed in the last decade. The nature of propellant flow in such micronozzles differs from that of macro nozzles. In micronozzles, ... En savoir plus
INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus
Alexander Frey received his M.A. degree from the University of Texas, Austin, in 1994, the Dipl. Phys. degree from the University of Wuerzburg, Germany in 1997 and the PhD from the Saarland University, Germany in 2010. In 1997 he joined Research Laboratories of Siemens working on the ...

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on ... En savoir plus
