Nonintrusive manipulation by standing-wave acoustics has been widely used for levitation and trapping of macroscopic objects.1 The standing-wave field creates an acoustic radiation force on the object that depends on its size and acoustic parameters.2 In the present article we demonstrate size-selective separation and retention of latex spheres inside a small-diameter flow-through capillary by use of an ultrasonic radiation trap. The work aims at rapid in-flow detection and separation of specific molecules via antibody-coated latex spheres. Ac ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

INTRODUCTION
Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year. Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit th ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

With in today's Internet data is transported using wavelength division multiplexed (WDM) optical fiber transmission system that carry 32-80 wavelengths modulated at 2.5gb/s and 10gb/s per wavelength. Today's largest routers and electronic switching systems need to handle close to 1tb/s to redirect incoming data from deployed WDM links. Mean while next generation commercial systems will be capable of single fiber transmission supporting hundreds of wavelength at 10Gb/s and world experiments have demonstrated 10Tb/shutdown transmiss ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

Charge Trapping Effects in High-k Transistors



Note, this is not a real abstract but a template based from the real one. Transition metal and rare-earth oxides comprise many of the high dielectric constant (high-k) materials currently being investigated for application as gate dielectrics in highly scaled transistors. A common electronic feature of these materials is the presence of d-shell states, which leads to their structural properties being drastically differe ....etc
