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

Hi,
I am Jayasree.N ; M.Tech student from Osmania University. Iam working on a Project: Optimal location of FACTS devices for improvemnt of Voltage Stability ; In this regard, could any one please mail me the MATLAB code for L index?

I have done loadflow for 30 bus system in NR method; got the Y bus matrix for IEEE 30 bus system. Now how to separate the load and generator buses -- some one please let me know.
Thank You

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

I am Manzil Duarah a B.E final year student. My seminar topic for my final semester is A very linear low pass filter with automatic frequency tuning. I don't have the necessary documents for making the seminar report. So i wanted the full text document on this topic. So i would be very thankful if you help me out.
The abstract of the topic is as follows :

Abstract
While the desire to support fast, ad hoc query processing for large data warehouses has motivated the recent introduction of many new indexing structures, with a few notable exceptions little attention has been given to developing new indexing schemes that allow fast insertions. Since additions to a large warehouse may number in the millions per day, indices that require a disk seek (or even a significant fractio ....etc

SCOPE
• How data is accessed and reconstituted joins
• Inform the user on how identify problems with SQL
Repair of SQL
• Tuning can occur at 2 levels
– Server ( DBA)
– SQL level ( User)
IMPORTANCE OF TUNING
• Reduce response time for SQL processing
• To find a more efficient way to process workload
• Improve search time by using indexes
• Join data efficiently between 2 or more tables
HOW TO TUNE
• Review the access path ....etc
