On Short Cuts - or - Fencing in Rectangular Strips [article]

Yaniv Altshuler, Alfred Bruckstein
2010 arXiv   pre-print
In this paper we consider an isoperimetric inequality for the "free perimeter" of a planar shape inside a rectangular domain, the free perimeter being the length of the shape boundary that does not touch  ...  rectangular, strip-shaped, "ring".  ...  This interpretation clearly explains the totally misleading title of our paper, in which we do not take any short-cuts and of course we do not discuss fencing as a sport that happens to be played on a  ...

Computer Aided Ore Body Modelling and Mine Valuation [chapter]

Kaan Erarslan
2012 Earth Sciences  
This type of sections are visualised on so-called fence diagrams (Fig. 18) . Parallel cross-sections of ore body are fundamental tools for 3D modelling.  ...  Regarding a cut-off grade, ore thicknesses are summed up to give ore thickness.  ...  The geological and other environmental processes on Earth and the composition of the planet are of vital importance in locating and harnessing its resources.  ...

The caddis flies, or Trichoptera, are for the most part medium-sized to small insects resembling moths in general appearance. Their larvae are aquatic in habit and caterpillar-like in appearance.  ...  In 1931, when this project was started, the only available listing of Illinois species was contained in Dr. Cornelius Betten's then unpublished manuscript of the Trichoptera of New York. In this. Dr.  ...  Metascutellum as wide as scutum, short and rectangular, fig. 438. . . .  ...
