Contributing causes include rim degradation by whole-body The surface of 243 Ida is dominated by the effects of impacts. ‘‘ringing,’’ relatively thin ejecta blankets around crater rims, No complex crater morphologies are observed. A complete or an extended strength gradient in near-surface materials due range of crater degradation stat...

S Xxvi Geology of Ida

Several lines of evidence from analysis of impact craters and other morphological features on Ida indicate the asteroid surface is covered with a thin layer of regolith that probably grades downward into less well-sorted rubble/megaregolith. This transition with depth is too gradational or occurs too close to the surface to be expressed in crater morphology at available resolution. Gravitationa...

Geology and geomorphology of Turkmenistan: A review

This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan. The basement of Turkmenistan is a complex amalgamation of arc-related terranes developed in the Asiatic and northern Paleotethys oceanic domains during Late Paleozoic to Triassic times. A major part of the country coincides with the Turan Platform, where a thick s...

SAC and neighbourhood SAC

This paper introduces a new kind of local consistency based on the general idea of singleton arc consistency (SAC). This is a reduced form of SAC that only considers neighbourhoods of a variable with a singleton domain; hence, the name “neighbourhood SAC” (NSAC). Like AC and SAC, NSAC has a unique fixpoint, so that NSAC algorithms will produce the same result when applied to a problem regardles...
