On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

SUPERCAPACITORS


Introduction


In power electronics, Electrical Energy Storage(EES) refers to the process of converting electrical energy from power into an electrical or non-electrical form that can be stored for converting back into electrical energy as per requirement.

This process enables electricity to be produced at time of either low demand, low generation cost and used at times of high demand, high generation cost or unavailability of other gener ....etc

Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces




Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds – nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , w ....etc

Supercapacitors Energy Storage System for Power Quality Improvement:



Introduction
The first complete electric power system was built by the Thomas Edison in September
1882 in the New York city ;through the steam driven dc generator supplying at 110 Volt.
Due to dc system and low voltage level; the losses in transmission line (I2R) puts the
limitation for the long distance transmission of the power. After development of the
transformer and ac transmissi ....etc
