This paper is concerned with the compact representation of execution sequences in terms of efficient looping constructs. Here, by a looping construct we mean a compact way of specifying a finite repetition of a set of execution primitives (“instructions”). Such compaction, which can be viewed as a form of hierarchical run-length encoding, has application in many embedded software contexts, incl...

Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

The present work manifests the results of the dynamic Young's modulus, E, after cold compaction and after sintering of partially dense copper and silver compacts. For both metals, the results show that E in the porous compacts depends not only on the attained density, but also on the samples' consolidation route. For porous metals, it is demonstrated that the normalized longitudinal sound wave ...

Compaction of porous rocks can occur in two modes: uniform and localized. Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly...
