Wind Power and Wind Turbines
Pressure
Wind – what causes it?, cont.
Pressure differences cause the flow of fluids (gases and liquids)
pressure is always measured relative to some reference pressure
Sometimes relative to vacuum  absolute
Sometimes relative to atmospheric pressure

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
c ....etc

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement
Mul ....etc

Abstract-


Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipat ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.
