This document provides guidance for technical managers for the reduction of risk to their computer systems and networks from attack by computer viruses, unauthorized users, and related threats. The guidance discusses the combined use of policies

Transfer function analysis of measured transfer matrices

August 1, 1989
Author(s)
Shao Yang, Igor Vayshenker, A. R. Mickelson
Measurements of mode transfer matrices of various multimode fiber optic connectors are presented. To analyze the accuracy and repeatability of such measurements, a theoretical framework which employs mode transmission functions is derived. It is shown that

Thermomechanical Detwinning of Superconducting YBa2Cu3O7-x Single Crystals

July 11, 1989
Author(s)
Debra L. Kaiser, Frank W. Gayle, Robert S. Roth, L Swartzendruber
A method for the complete removal of twins from single crystals of superconducting YBa2Cu3O7-x is described. The process depends on ferroelastic behavior found to exist in the phase, and should be generally applicable to the layered perovskite-type phases
