TL;DR: In this article, a data structure for use in a document processing system corresponds to a document comprised of one or more Pages, each Page is subdivided into nonoverlapping Areas, each Area in turn being comprised of a particular type of information such as text or graphics information.
Abstract: A data structure for use in a document processing system corresponds to a document comprised of one or more Pages. Each Page is subdivided into one or more nonoverlapping Areas, each Area in turn being comprised of one or more types of Layers. Each Layer type is expressive of a particular type of information such as text or graphics information. Different Layer types may be superimposed to comprise the contents of an Area.

TL;DR: This document is the reference manual for layer 2 of LMA and contains the information necessary to write LMA-based systems at the level of layer 3.
Abstract: Logic Machine Architecture (LMA) is a package of software tools for the construction of inference-based systems. This document is the reference manual for layer 2 of LMA. It contains the information necessary to write LMA-based systems at the level of layer 3. Such systems include theorem provers, reasoning components for expert systems, and customized deduction components for a variety of application systems.

TL;DR: It is shown how one-layer routings obtained under the no component constraint assumption can be utilized for two-layer routing under a conventional VLSI model (i.e., one with component constraints).

TL;DR: The Reference Model provides a framework for the development of standards for the interconnection of computer and terminal equipment and describes an architecture wherein functions ascribed to providing communications are separated into a hierarchy of seven layers.
Abstract: A great deal has already been written about the development by the International Organization for Standardization of a Reference Model for Open Systems Interconnection. The Reference Model provides a framework for the development of standards for the interconnection of computer and terminal equipment. It describes an architecture wherein functions ascribed to providing communications are separated into a hierarchy of seven layers. Each layer provides services to the next higher layer, utilizing the services provided by subordinate layers in order to achieve that end. At each layer, protocols are employed to convey information between peer layer entities in individual systems. When in compliance with a suite of standard protocols prescribed for OSI, systems are considered to be "open".

TL;DR: The purpose of this paper is to provide a design example of an authentication service as a means of privacy in information exchange between presentation entities.
Abstract: The purpose of this paper is to provide a design example of an authentication service as a means of privacy in information exchange between presentation entities. The service is contained in the session layer and interfaces with the lower layer transport service and upper layer presentation entities. The transport layer service interface is defined to be compatible with the DoD IP/TCP standard and the NBS proposed ISO transport standard.
