Introduction: Hal Wallace‚ the President of the Wallace Group Inc‚ Inc. runs a manufacturing company consisting of three operational groups; electronics‚ plastics and chemicals. In terms of sales volumn the plastic and chemical groups are comparable; however both groups combined equal approximately the size of the electronics group alone. Originally each group began as a sole proprietorship under direct operating control of Hal Wallace. Currently Hal Wallace is serving as Chairman as well as

1.) How gating of a thyristor works? A thyristor is a 4 layer 3 terminal device with 3 junctions. When the anode terminal has positive voltage and no gate voltage is applied‚ the first and the third junction are forward biased and the second junction is turned reverse biased allowing no current flow through the thyristor. A thyristor starts to conduct when the voltage across the anode and cathode (VAK) is increased beyond the thyristors breakdown voltage (VBO). This is

CHAPTER I Potatoes as Other Point of Supply for Batteries I. Background of the Study For the past few years‚ researcher Rabinowitch and colleagues have been pushing the idea of “potato power” to deliver energy to people cut off from electricity grids. As a resident living in the Philippines wherein most perilous typhoons happen‚ Filipinos experience tough challenges like the cut off of the electricity or most

and buried cables. Laser communications systems can be easily deployed since they are inexpensive‚ small‚ low power and do not require any radio interference studies. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed‚ one for transmission and one for reception. INTRUDUCTION: Laser Communication is one of the emerging area of wireless communication system. Due to its low noise ratio makes its one of the well suited communication

Electronic WorkBench tutorial Introduction Electronic WorkBench (EWB) is a simulation package for electronic circuits. It allows you to design and analyze circuits without using breadboards‚ real components or actual instruments. EWB’s click-anddrag operations make editing a circuit fast and easy. You can change parameters and circuit components on the fly‚ which make "what-if" analysis straight foreward. This tutorial is intended as a quick introduction to EWB’s basic features. It first
