We propose a simple and effective method for detecting view- and scale-independent ridge-valley lines defined via first- and secondorder curvature derivatives on shapes approximated by dense triangle meshes.

高的工作电压高达100V N双N沟道MOSFET同步驱动 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

On Sunday, April 27, 2003, Fresno will celebrate Earth Day in downtown Fresno at Courthouse Park. The event will begin at noon. This year we will include music, speakers, and vendors, plus activities for children. Fresno Earth Day is recognized as the only Earth Day festival that happens in Fresno, and the largest in the Central valley. The Fresno Earth Day Committee is a small group of environmental activists hoping to broaden the appeal of a better planet and environment. We are a non-profit organization whose fiscal fiduciary is the Fresno Center for Nonviolence.

Managing Humans is a selection of the best essays from Michael Lopps web site, Rands In Repose. Drawing on Lopp s management experiences at Apple, Netscape, Symantec, and Borland, this book is full of stories based on companies in the Silicon valley where people have been known to yell at each other. It is a place full of dysfunctional bright people who are in an incredible hurry to find the next big thing so they can strike it rich and then do it all over again. Among these people are managers, a strange breed of people who through a mystical organizational ritual have been given power over your future and your bank account. Whether you re an aspiring manager, a current manager, or just wondering what the heck a manager does all day, there is a story in this book that will speak to you. You will learn: * What to do when people start yelling at each other * How to perform a diving save when the best engineer insists on resigning * How to say "No" to the person who signs your paycheck

With the rapid development of electric vehicles (EVs) as well as the promotion and application of vehicle-to-grid (V2G) technologies, EVs charging loads, as flexible loads, have the potential to participate in the grid services, including peak shaving and valley filling, frequency regulation (FR), emergency power, energy market participation, and so on. Therefore, great attention has been paid to EVs and V2G. Focusing on the interactions between EVs and power system, this book aims to bring readers with basic knowledge of electrical engineering promptly to the frontier of the EVs’ influence on power system and environment. This book may serve as a reference for scientists, electrical engineers, and postgraduate students majoring in electrical engineering or other related fields.
