Electrical discharge as an inspection method for imperfect plasma display cells

An energy-recovery sustaining driver with discharge current compensation for AC plasma display panel

A novel driver with discharge current compensation is proposed to drive an ac plasma display panel (PDP). This proposed circuit uses resonance between the inductor and the ac PDP to avoid abrupt charging/discharging. The four switches of the full bridge are all operated with zero-voltage-switching turn-on. In addition, an 8-in ac PDP equipped with the proposed driving circuit, operating at 100 ...

SILAR Sensitization as an Effective Method for Making Efficient Quantum Dot Sensitized Solar Cells

CdSe quantum dots were in situ deposited on various structures of TiO2 photoanode by successive ionic layer adsorption and reaction (SILAR). Various sensitized TiO2 structures were integrated as a photoanode in order to make quantum dot sensitized solar cells. High power conversion efficiency was obtained; 2.89 % (Voc=524 mV, Jsc=9.78 mA/cm2, FF=0.56) for the cells that sensitized by SILAR meth...

Imperfect Inspection Games Over Time

Novel Tool Design Method for Orbiting Electrical Discharge Machining *

Orbiting EDM has the advantages of superior machining quality over static EDM due to advanced flushing. However, improper tool correction to the relative motion in orbiting EDM will result in dimension errors of the product. As features vary in morphology, tool design for orbiting EDM is a challenging task, particularly for mould comprises assorted features. A strategy for correcting the orbita...

Economic-Statistical Design of a Control Chart for High Yield Processes When the Inspection is Imperfect

CCC-r control chart is a monitoring technique for high yield processes. It is based on the analysis of the number of inspected items until observing a specific number of defective items.  One of the assumptions in implementing CCC-r chart that has a significant effect on the design of the control chart is that the inspection is perfect. However, in reality, due to the multiple reasons, the...
