IEEE TRANSACTIONS ON POWER ELECTRONICS‚ VOL. 26‚ NO. 2‚ FEBRUARY 2011 399 A Nonlinear-System Approach to Analysis and Design of Power-Electronic Converters With Saturation and Bilinear Terms Tingshu Hu‚ Senior Member‚ IEEE Abstract—Power-electronic converters are intrinsically nonlinear. This paper proposes a Lyapunov approach to analysis and design of a class of nonlinear systems arising from power-electronic converters. The system has a bilinear term as the product of the state and

Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber‚ with each signal carried at the same time on its own separate light wavelength. Using DWDM‚ up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a light stream transmitted on a single optical fiber. Each channel carries a time division multiplexed (TDM) signal. In a system with each channel carrying 2.5 Gbps (billion bits per

INTRODUCTION The current ultramodern technologies are focusing on automation and miniaturization. The decreasing computing device size‚ increased connectivity and enhanced interaction with the physical world have characterized computing history. Recently‚ the popularity of small computing devices‚ such as hand held computers and cell phones; rapidly flourishing internet group and the diminishing size and cost of sensors and especially transistors have accelerated these strengths. The emergence

Human Eye Vs. Animal EyeBy:Andrea Torres ABSTRACT The tapetum lucidum is an evolutionary advantage for animals. It enables animals to see in dimmer light than the animal would otherwise be able to see in. The tapetum lucidum is useful to animals‚ but it also has a use to humans. Human beings use the tapetum lucidum to scan for reflected eye-shine‚ in order to detect and identify the species of animals in the dark and to send trained search dogs and search horses out at night. Historically

Copper vs Fiber Some advantages of Copper Cabling are Power over Ethernet this gives you the ability to power phones‚ surveillance cameras‚ Wireless Access Points‚ and many other devices right through the networking cable itself. That means that you don’t have to schedule an electrician in to run power to your surveillance cameras to power them. Another advantage is the ability to have an emergency power supply that will continue powering mission critical devices even if your electricity goes

The Nonlinear Structure of The Sorrow of War and its Distortion of Kien and Phuong’s Relationship to Create Character Depth to Kien Bao Ninh is a Vietnamese war veteran and the author of what is said to be "one of the most moving war novels of all time" (Gareth Smith)‚ The Sorrow of War. In the epic tale‚ Bao tells the story of Kien in a nonlinear narrative‚ weaving in and out of stories of young love and war‚ each failing to complete its own objectives: to come home and live in peace with those

To best describe DWDM (coarse wavelength division multiplexing) and DWDM (dense wavelength division multiplexing)‚ you must first understand how WDM (wavelength division multiplexing) operates. WDM is multiplexing several optical signals on a single fibre by using wavelengths which are essentially colours of the laser light; to transmit different signals ranging from 2.5Gbps to 40Gbps. The device that connects the signals together is a multiplexor‚ and the one that splits them apart on the other
