A novel square equal-area map projection is proposed. The combines closed-form forward and inverse solutions with relatively low angular distortion minimal cusps, a combination of properties not manifested by any previously published projection. Thus, the new has lower than solution. Utilizing quincuncial arrangement, places north pole at center divides south between its four corners; can be se...

The aim of this paper is to motivate the development of a Brunn-Minkowski theory for minimal surfaces. In 1988, H. Rosenberg and E. Toubiana studied a sum operation for finite total curvature complete minimal surfaces in R3 and noticed that minimal hedgehogs of R3 constitute a real vector space [14]. In 1996, the author noticed that the square root of the area of minimal hedgehogs of R3 that ar...

Subalpine rangeland as a rara avis ecosystem is very important because ofecological features. Consistency and resistance of this ecosystem is so frangible and itsnatural equilibrium is instable due to the effects of biotic and abiotic factors. The landslideas one of negative consequences in upland area is seen in Masoleh watershed (north ofIran). This study has investigated the roles of biotic ...

INTRODUCTION AND OBJECTIVES Intracoronary ultrasound estimation of the functional significance of intermediate angiographic lesions has mainly been based on measuring the minimal lumen area. These estimates take no account of lesion length and pay insufficient attention to long coronary lesions. METHODS We included 61 lesions with visual angiographic stenosis of 40% to 70% that required treat...

We study the problem of shape reconstruction from stereo images based on a weighted area minimization process of a depth function. As a simple example we present an efficient shape reconstruction from computer generated autostereograms. A minimal surface area based correlation is applied to accurately reconstruct the surface structure embedded first in one autostereogram image and next in two o...
