This approach would reduce the duration of the thermal response test in single strata subsurface ground zone.
The CBTC system consists of ground zone controllers (ZC), the on-board equipment, the bidirectional train ground information transmission system, and the train positioning system (as shown in Fig. 1).
Buried landforms interpreted as lateral moraines and a grounding-zone wedge record the positions of still-stands or re-advances in the ice margin.
A number of buried glacigenic landforms, including palaeo-shelf break gullies and a grounding-zone wedge with a volume of 90 km3, are described from the Amundsen Gulf Trough stratigraphy.
Lateral grounding-zone wedges are identified at the northern and southern lateral margins of the Amundsen Gulf and M'Clure Strait troughs, respectively, and are interpreted to have been formed roughly contemporaneously by ice streams in Amundsen Gulf and M'Clure Strait.
At sufficiently low frequencies it is shown that the interaction of the surface irregularities with the near field of a ground-based source leads to the production of "surface waves", which are effective in penetrating the ground shadow zone predicted for a smooth surface of the same impedance.
A fragmenting electorate had abandoned the centre-ground comfort zone well before Corbyn threw his cap into the ring.
"We face problems," Mr. Kostunica said, "before our domestic public and even before history whether the Albanian terrorists will remain in the ground safety zone or not.
Only lightly armed Serbian police officers are allowed to operate in the "Ground Safety Zone," as it is called, and the peacekeepers are allowed to enter only under extraordinary conditions.
To separate NATO forces from the Yugoslav Army, Belgrade agreed to a three-mile-wide "ground safety zone," bordering Kosovo but inside Serbia, from which all Serbian forces are banned, except police officers with light weapons.
