Method for increase in sensitivity of the ignition center coordinate pyrometric detector
The article describes the method for increase in sensitivity of the pyrometric detector for detection of ignition center based on two-dimensional coordinates by means of the mirrors located behind cylindrical lenses.
Detection time of the explosion initial stage by the electro-optical system with cylindrical lenses
The arcticle is devoted to the experimental investigations of the electro-optical system (EOS) with cylindrical lenses. It was proved the efficiency of the system and defines the detection time of the explosion initial stage.
The Mound on the Mount: A Possible Solution to the Problem with Jerusalem
Following Knauf's suggestion (2000), the article raises the possibility that in most periods in the second and first millennia BCE the main built-up area of Jerusalem was limited to a mound on the Temple Mount. This mound, which may have covered an area of five hectares and more, was boxed-in under the Herodian platform. At these periods activity in the City of David ridge was restricted to the area near the Gihon spring. In the Iron IIB and late Hellenistic Periods the fortified settlement expanded simultaneously to both the City of David ridge and the southwestern hill. In these two periods there was no need to fortify the western side of the City of David, as this line ran in the middle of the city.
