TL;DR: A thermal design approach emphasizing the coupling of heat transfer theory and experiment to basic reliability considerations is illustrated by discussing typical thermal problems on several system integration levels for a high reliability, multi-cabinet hybrid computer system.
Abstract: Thermal design and analysis are important in Reliability/Availability/Maintainability R/A/M programs for electronic systems. A thermal design approach emphasizing the coupling of heat transfer theory and experiment to basic reliability considerations is illustrated here by discussing typical thermal problems on several system integration levels for a high reliability, multi-cabinet hybrid computer system. This paper emphasizes a particular attitude toward the thermal aspects of equipment design, one that is flexible in the methods of analysis, comprehensive in its treatment of each integration level in a complementary fashion, and oriented toward the goals of the R/A/M program as a whole. The examples show that conventional analytic solutions, when coupled with reliability theory and a modicum of experimental results, lead to effective thermal design.

TL;DR: In this article, the No. 4 ess toll system is described and the special equipment and test procedures developed for system-testing are described, as well as the early field experience with the first operational office.
Abstract: This article describes the special equipment and test procedures developed for system-testing the No. 4 ess toll system. It discusses novel methods developed for the coordination of hardware and software changes and testing in various system laboratory configurations. Planning, engineering, installation, and testing of early offices are described. Early field experience with the first operational No. 4 ess is presented. This office, a selective routing tandem located in Chicago, went into service on January 17, 1976.

TL;DR: The OMEGA laser irradiation facility as mentioned in this paper was designed as a National "Users" facility for laser-matter interaction studies on spherical targets, with a focus on the laser system, target system and control room.
Abstract: The OMEGA laser irradiation facility is described with particular emphasis on the laser system, target system and control room. Some of the major systeths integration efforts are explained as well as their interactions. Design considerations and their impact on system performance and schedule are discussed. The problems of operating a users' facility for laser interaction experiments are mentioned. The Laboratory for Laser Energetics at the University of Rochester has designed and is preparing to construct a 30 terawatt neodymium glass laser irradiation facility, called OMEGA, for experiments in laser fusion. This paper describes the various subsystems contained in the facility and some of the requirements for system integration. A detailed description of the Beam Synchronization Subsystem is included as a specific example of the complex systems integration effort involved in the construction of the OMEGA system. OMEGA is designed as a National "Users" facility for laser-matter interaction studies on spherical targets. Figure 1 lists the general system objectives in terms of the overall characteristics and requirements for this sort of facility.© (1977) COPYRIGHT SPIE--The International Society for Optical Engineering.

TL;DR: This paper will present the time division data bus evolutions, its standardization and application, and the acquisition management and logistic benefits will be discussed.
Abstract: Summary Today, avionics are demanding an increasing proportion of the resources available for aircraft weapons systems. These avionics are providing increased capability and accuracy to the aircraft weapon system; but, also are a prime contributor to increased complexity and decreased reliability of the system. Digital avionics appears to offer the desired increase in capabilities and performance without the normal companions of low reliability, complexity, and high cost because it is amenable to mechanization via solid state devices; it is more orderly and systematic, and provides growth and change without major hardware modification. Digital avionic integration, in order to reap these benefits, requires standard equipment interfaces and a standard approach to data intercommunication. The time division data bus is the technique that permits this new concept of system integration to emerge. This paper will present the data bus evolutions, its standardization and application. The acquisition management and logistic benefits will be discussed. Definitions

TL;DR: In this paper, an integrated avionics system design was carried out to the level which indicates subsystem function, and the methods of overall system integration, and sufficient detail was included to allow identification of possible system component technologies, and to perform reliability, modularity, maintainability, cost and risk analysis upon the system design.
Abstract: An integrated avionics system design was carried out to the level which indicates subsystem function, and the methods of overall system integration. Sufficient detail was included to allow identification of possible system component technologies, and to perform reliability, modularity, maintainability, cost, and risk analysis upon the system design. Retrofit to older aircraft, availability of this system to the single engine two place aircraft, was considered.

TL;DR: The main goal of this workshop was to aid IIASA in identifying the most advanced methods for planning, scheduling and production control, and to determine how these methods can be implemented and coordinated to achieve systems integration.
Abstract: Interest in computer based management systems in the steel industry can be attributed to three main reasons. First, steel is a basic industry that is of interest to most of the IIASA NMOs. Second, steel is a complex industry with different types of processing and manufacturing facilities. Third, and most important, the steel industry is perhaps the most advanced area of technology with respect to the application of both an integrated systems approach and computers for real time information processing and decision making. The major goal of this workshop was to aid IIASA in identifying the most advanced methods for planning, scheduling and production control, and to determine how these methods can be implemented and coordinated to achieve systems integration. The proceedings of this workshop deal with problem oriented models for industrial technology -- specifically with the application of computers for the control of basic oxygen furnaces. A review of the present practices in nine countries, including Japan, the USA and the USSR, are presented, along with suggestions for further IIASA research.

TL;DR: In this article, the authors describe the planning process that was used in the design of an integrated fixed-and flexible-route system in one suburb of Rochester, New York, which is one component of a federal demonstration project designed to evaluate the feasibility of such systems in major metropolitan areas.
Abstract: Demond-responsive transportation is an accepted form of transportation in small and medium-size cities. However, as these types of systems are introduced into larger urban areas that already have fixed-route services, the systems and the preceding planning process necessarily become more complex. This paper describes the planning process that was used in the design of an integrated fixed- and flexible-route system in one suburb of Rochester, New York. The system is one component of a federal demonstration project designed to evaluate the feasibility of such systems in major metropolitan areas. A description is given of the planning approach taken and the methodologies and analyses used. The use of a simulation model to determine the extent of the dial-a-bus service area in the suburban and a logit model to predict the expected demand for such service is described. In addition, the methodology developed for the system integration design, i.e., the combination and coordination of existing bus service with flexible-route services, is explained. Provision of opportunities for public involvement during the planning process is also described. /Author/
