Abstract
MEMS varactors are one of the important passive MEMS devices. Their applica- tions include use in VCOs, tunable impedance matching networks, tunable ¯lters, phase shifters, and true time delay lines. The shunt capacitive structure has been employed in most of the conventional MEMS varactor designs because of its simplicity. However, the capacitance ratio of this conventional shunt capacitive MEMS varactor is limited to 1.5 because of the MEMS Pull- In e®ect, which happens when the de°ection between the MEMS top and bottom m ....etc

INTRODUCTION TO PLC
1. Programmable Logic Controller
A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on. Where ever there is a need to control devices the PLC provides a flexible way to software the components together.
The basic units have a CPU (a computer processor) that is dedicated to run one program that monitors a series of differen ....etc

Evil Twin is a term for a rogue Wi-Fi access point that appears to be a legitimate one offered on the premises, but actually has been set up by a hacker to eavesdrop on wireless communications among Internet surfers. This type of Evil Twin Attack may be used by a hacker to steal the passwords of unsuspecting users by either snooping the communication page link or by phishing, which involves setting up a fraudulent Web site and luring people there. A rogue Wi-Fi connection can be set up on a laptop with a bit of simple programming and wireless c ....etc

ZFS Filesystem
Abstract
ZFS: the last word in file systems Most system administrators take the limitations of current file systems in stride. After all, file systems are what they are: vulnerable to silent data corruption, brutal to manage, and excruciatingly slow. ZFS, the dynamic new file system in Sun\'s Solaris 10 Operating System (Solaris OS), will make you forget everything you thought you knew about file systems. It offers: €¢ Simple administration ZFS automates and consolidates complicated storage adm ....etc

SYNOPSIS

NAME: ZFS FILE SYSTEM



AREA: FILE SYSTEM



ORIGIN:

FS was designed and implemented by a team at Sun led by Jeff Bonwick. It was announced on September 14, 2004. Source code for ZFS was integrated into the main trunk of Solaris development on October 31, 2005 and released as part of build 27 of OpenSolaris on November 16, 2005. Sun announced that ZFS was included in the 6/06 update to Solaris 10 in June 2006, one year after the opening of the OpenSolaris community.

The name originally stood for Zet ....etc
