SUPER BRIGHT LED FLASHER




This is a novel flasher circuit using a single driver transistor that takes
its flash-rate from a flashing LED. The flasher in the photo is 3mm. An
ordinary LED will not work. The flash rate cannot be altered by the
brightness of the high-bright white LED can be adjusted by altering the
1k resistor across the 100u electrolytic to 4k7 or 10k. The 1k resistor
discharges the 100u so that when the transistor turns on, the c ....etc

1. ABSTRACT:
In modern power systems network, it is essential to transmit power from one region to another region in order to meet the load demands. This can only possible by having Asynchronous power transmission between two regions operating at different frequency. This Asynchronous power transmission is called HVDC transmission.
Beginning with a brief historical perspective on the development of High Voltage Direct Current (HVDC) transmission systems, this paper presents an overview of the ....etc

ADVANCED IC PACKAGING TECHNOLOGIES
Abstract

ADVANCED IC PACKAGING TECHNOLOGIES The many different functions of semiconductor devices are made possible by integrated circuits, which are built into the surface of a silicon chip (bear chip) using a complex process. If these chips could be used in unmodified form, packaging would be unnecessary, and the cost of chips reduced. However, because silicon chips are very delicate, even a tiny speck of dust or drop of water can hinder their function. Light can also cause malfunctions. To combat ....etc

FACTS is a concept introduced by Electric Power Research Institute (EPRI), U.S.A.It is actually a group of advanced transmission technologies that rely on high speed, solid-state electronics, rather than electromechanical devices.

By this concept, the apparent impedance of a transmission line is controlled according to certain algorithm. Thus the power system operation is made more reliable, controllable and efficient. The FACTS system is a promising method, which can be implemented into the system for enhancing system stability by damping ....etc

Advanced technologies in water and wastewater treatment



Introduction
Conventionalwater andwastewater treatment processes have
been long established in removing many chemical and microbial
contaminants of concern to public health and the environment.
However, the effectiveness of these processes has become
limited over the last two decades because of three new
challenges (Langlais et al. 1991; Mallevialle et al. 1996). First,
