Abstract
This presentation describes a new valveless micropump for bidirectional use. The micropump was fabricated by bonding a fluidic channel and a membrane actuator. The fluidic channel was etched on a glass substrate and the membrane actuator was made on a silicon wafer. The membrane is actuated by a piezoelectric ceramic (PZT) plate so that the membrane generates blowing and suction flows successively along an oblique channel which is connected to the main channel. A blowing flow from an oblique channel into the ma ....etc

Introduction
A number of different micropumps have been developed over the last decades. Among the various kinds of working principles, the micropump using membrane actuation is known as a promising approach. Therefore, a lot of membrane micropumps have been studied with various actuators. The valve is another issue for the development of micropumps. Since a piezoelectric micropump with check valves was first presented by Van Lintel et al. , passive or active check valves have been widely used for micropumps. The micropump with check valves ....etc

PULSE JET ENGINE
What is Pulse Jet ?
• Simple form of internal combustion engine
– Combustion occurs in pulses
» Termed deflagrations
» Characterized by sudden rise in temperature and pressure followed by a rapid subsonic expansion
– Propulsive effort is a rearward reaction to hot gases
HISTORY
• Patented in 1906 by Russian engineer V.V Karavodin
• In the 1933 German engineer Paul Schmidt re-discovered the princi ....etc

Abstract
Mounting engines on the wing causes complex wing
flutter characteristics. The location of the engine mass
and the stiffness of the pylon relative to the wing are
important in preventing hazardous wing flutter. In
addition, if the nacelles are installed over the wing,
aerodynamic interference between the wing and the
nacelle may cause unfavorable flutter characteristics, in
particular, at transonic speeds. The flutter
characteristics of an over-the-wing engine mount
configuration obtained from theoretical analyses and

Pulse Shape Improvement in Core-Type High-Voltage Pulse Transformers With Auxiliary Windings
High-voltage pulsed power technologies are rapidly emerging as a key to efficient and flexible use of electrical power for many industrial applications. One of the most important elements in high-voltage pulse-generating circuit technology is the transformer, generallyused to further increase the pulse output voltage level. However, its nonideal behavior has significant influence on the output pulse shape.The most attractive winding configurati ....etc
