Approximating a topological section by a piecewise-linear section

Approximating Points by a Piecewise Linear Function: I

We study the problem of approximating a set of weighted planar points by a step function, and the problems of approximating non-weighted and weighted planar points by a (more general) piecewise linear function. We either improve the previously best-known results or give the first-known results for these problems. Our algorithms are based on interesting and nontrivial geometric techniques and da...

This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

A Monograph of Verticillium Section Prostrata

Section Prostrata of the genus Verticillium was introduced by GAMS (1971) to separate verticillium-like anamorphs of the Clavicipitaceae from other species of the genus that were known or supposed to have affinities with other families of the Hypocreales. Other sections of Verticillium were subsequently described by GAMS & VAN ZAAYEN (1982). MESSNER et al. (1996) showed that the most important ...

The Diagnostic Accuracy of Frozen Section Compared to Permanent Section: A Single Center Study in Iran

Background:The diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. In this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in Iran. Methods: We retr...
