The gas turbine has been an enormously successful power plant for aircraft and marine propulsion, and electric power generation, due to its lightweight, smooth and reliable operation, low emissions, and varied applications. Nevertheless, it is not very efficient in converting fuel energy to useful work, due to fundamental thermodynamic limitations imposed by turbo machinery technology.

In recent years, there is renewed interest in the potential high efficiency of alternative thermodynamic cycles and unsteady combustion systems for propulsi ....etc

INTRODUCTION
If you're thinking about assembling a home theatre system, you may be looking at large screen televisions as the heart of your system. Projection TV could give you the size that you want -- CRT screens generally top out at 40 (101 cm) or so, and at that size, they are huge and heavy. Plasma screens can be bigger than that and still manageable, but they can be extremely expensive. Projection TV technology can create large screen sizes at a reasonable price. Or maybe you need to equip a room, like ....etc

Abstract-
A pulse skipping control strategy is proposed to improve efficiency of grid-tied inverters at light loads. To maximize the efficiency of pulse skipping operation mode, three key parameters are identified and optimized based on a loss model, which is developed to find the maximal efficiency points using a three-dimensional search technique. A 200W prototype inverter was setup to verify the proposed control strategy. The experimental results show that the proposed pulse skipping control strategy greatly impr ....etc

Efficiency Improvement of WCDMA Base Station Transmitters using Class-F power amplifiers

Muthuswamy Venkataramani



(ABSTRACT)
Universal Mobile Telecommunications Systems (UMTS) is the preferred third generation (3G) communication standard for mobile communications and will provide worldwide coverage, a convenient software technology and very high data rate. The high data rate, especially, requires the use of bandwidth-efficient modulation schemes such as Quadrature Phase Shift Keying (QPSK). But mo ....etc

INTRODUCTION
AD HOC Network a wireless network in which all the nodes are free to move randomly and organize themselves arbitrarily.
Sending along a packet from a source to a destination in an hoc network is a challenging problem.
The main source of the challenges comes from that - no base stations in these networks,- therefore th ....etc
