Taschenbuch. Condición: Neu. Neuware - Random phase screens are essential elements of simulating light propagation through turbulent media. In order to be e ective, they must accurately re-ect theory and be implementable by the user. This document explains and evaluates three methods of generating random phase screens: using a Fourier series upon a polar frequency grid with logarithmic spacing; using the fast Fourier transform, with its cartesian frequency grid; and using Zernike polynomials. It provides a comparison of the polar Fourier series technique with the two more common techniques (fast Fourier transform and Zernike), with the end result of giving the users enough information to choose which method best ts their needs. The evaluation criteria used are generation time (usability) and phase structure function (accuracy).…

The book was created at Columbia University's Watson Scientific Computing Laboratory to chronicle the development of the IBM Naval Ordnance Research Calculator (NORC), which was the most powerful computer in the world at the time of its debut. Authors Wallace Eckert and Rebecca Jones famously pioneered the early programming and orbital calculations that would later lay the groundwork for NASA's Apollo missions. Written explicitly to demystify "giant electronic calculators" for a mid-century public, this highly collectible volume captures a historic moment when vacuum tubes and magnetic tape were first rewriting the limits of human calculation. --- General Info: Title: Faster, Faster - A Simple Description of a Giant Electronic Calculator and the Problems it Solves Author: W.

Hardcover. Condición: Very Good. 1st Edition. Jones co-authored with Eckert this book during the very early days of the IBM Naval Ordnance Research Calculator, the first supercomputer. The Naval Surface Weapons Center at Dahlgren, Virginia, was the primary site of US naval computing. The center's machine, the Naval Ordnance Research Calculator (NORC), was built at the Watson Scientific Computing Laboratory under the direction of Wallace Eckert. Rebecca (Becky) Jones, an Associate in Astronomy at Columbia, was Wallace Eckert's assistant for many years and (also with Eckert) specified the first program for the SSEC (the moon orbit calculations that would be used later in the Apollo missions. Old signature inside the front cover, edges rubbed, in very good condition otherwise. A rare computer science work. Size: 6" - 9½". book.…
