Alma Front Ends

Electromagnetic properties and optical analysis of the ALMA antennas and Front Ends

Alma: a Generic Program Animation System

In this paper, a system for program animation is presented. Alma system receives as input a computer program and produces a sequence of visualizations that will describe its functionality. The system generates automatically program animations basing this process on the internal representation of those programs. We do not rely upon any source program annotations (visual/animation statements, or ...

Some biological parameters of Silver Crucian carp, Carassius auratus, in the international wetlands of Alma-Gol and Ala-Gol (Golestan Province, Iran)

In the present study, age, growth and reproduction of Carassius auratus were investigated in the Alma-Gol and Ala-Gol (northern Iran) from September 2000 to August 2002. Among the total of 1450 specimens, the estimated ages ranged from 0+ to 8+ years. C. auratus showed an allometric growth, negatively in Alma-Gol and positively in Ala-Gol. The von Bertalanffy growth curves were fitted to mean t...
