The Effectiveness of Dynamic Voltage Restorer with the Distribution Networks for Voltage Sag Compensation

This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...

Roentgen Methods for Routine Obstetrical Pelvimetry *

The application of roentgen methods to pelvimetry has been an interest in this dinic for the past fifteen years and during that time a number of communications on the subject have appeared as a result of our experience. In March, 1937, we described7 a modification of the technic for producing lateral roentgenograms, and since that time we have added this projection to our grid method of superio...

Response of CR-39 to Heat Exposure

As a nuclear track detector, CR-39 (polyallyl diglycol carbonate) is used to reveal the products of fusion reactions. Positioned around the OMEGA target chamber, pieces of CR-39 absorb and are damaged by ejected particles. The plastic is then etched in NaOH solution at 80°C for 6 hours, resulting in the formation of nuclear tracks visible under a digital microscope. The etching process also rev...
