This article describes the design of the DMERT operating system nucleus.

The 3B20D Processor has extensive maintenance subsystems associated with it and is designed to meet the high-availability standards of Bell System electronic switching systems.

An integral part of high-reliability applications of the Duplex Multiple Environment Real Time (DMERT) operating system is the administration of system hardware information and of software.

An important aspect of the development of any complex system such as the 3B20D Processor is the methodical integration and system testing during all phases of the development consistent with the ex

The 3B20D Processor is the first member of a family of processors designed for a broad range of Bell System applications.

The direct predecessor of the 3B20D, the 3A Processor, included a real-time monitor known as the Extended Operating System (EOS).

The software that comprises the operating system, diagnostics and fault recovery, configuration data base, field utilities, and craft interface for the 3B20D Processor has been undergoing developme

In this paper, we introduce a completely new approach to fitting implicit polynomial geometric shape models to data and to studying these polynomials.

This paper studies the set of cycles under iteration of the (3x + k)-function T sub k (n) = sup 3n+k over 2 if n is odd, n over 2 if n is even, where k varies over all positive integers relatively
