An in-vehicle information system (IVIS) has been developed designed to evaluate the demands placed on drivers attentional resources. A behavioral model predicting the driver's interaction with the program was analyzed. A prototype software package was used to evaluate the attention demand required to operate a given IVIS. The developmental and functional aspects of the program provided information on the status of the prototype software.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

Magnetohydrodynamic propulsion systems for submarines offer several significant advantages over conventional propeller propulsion systems. These advantages include the potential for greater stealth characteristics, increased maneuverability, enhanced survivability, elimination of cavitation limits, greater payload capability, and the addition of a significant emergency propulsion system. These advantages can be obtained with a magnetohydrodynamic propulsion system that is neutrally bouyant and can operate with the existing submarine propulsion system power plant. A thorough investigation of magnetohydrodynamic propulsion systems for submarine applications has been completed. During the investigation, a number of geometric configurations were examined. Each of these configurations and mounting concepts was optimized for maximum performance for a generic attack class submarine. The optimization considered each thruster individually by determining the optimum operating characteristics for each one and accepting only those thrusters that result in a neutrally buoyant propulsion system. The results of this detailed optimization study show that the segmented, annular thruster is the concept with the highest performance levels and greatest efficiency and offers the greatest potential for a practical magnetohydrodynamic propulsion system for attack class submarines. The optimization study results were used to develop a specific point design for a segmented, annular magnetohydrodynamic thruster for an attack class submarine. The design point case has shown that this thruster may be able to provide the necessary thrust to propel an attack class submarine at the required velocity with the potential for a substantial acoustic signature reduction within the constraints of the existing submarine power plant and the maintenance of neutral buoyancy. This innovative magnetohydrodynamic propulsion system offers an approach for submarine propulsion that can be an important contributio

A Frame-Based Mission Decomposition Model

引用

Proceedings of the human Factors and Ergonomics Society Annual Meeting 1988年第2期32卷 135 - 139页

作者： Gilbert G. Kuperman William A. Perez Crew Systems Integration Branch Human Engineering Division Armstrong Aerospace Medical Research Laboratory Wright-Patterson Air Force Base Ohio Human Engineering Program Office Systems Research Laboratories Inc. Dayton Ohio

This paper presents the results of a mathematical modeling (computer simulation) effort that applied frame-based, data processing constructs, originally developed and applied in the context of artificial intelligence, to the decomposition of a complex Air Force bomber mission. The model was written in LISP to facilitate the development of a concurrent processing environment in which to simulate the simultaneous occurrence of multiple external events/crew tasks. The model simulated a four hour segment of a strategic mission scenario. Two distinct crew complements, four-man and two-man, together with their respective levels of aircraft avionics automation, were represented during a proof-of-concept demonstration. The model provided measures of resource (crew and “black box”) utilization, presumed to correlate to “workload,” at different levels of specificity. These measures were used to identify crew task “chokepoints” (large queue sizes, task interrupts) and to evaluate the effects of automation.

A Signal Detection Paradigm for Color Display Specification

引用

Proceedings of the human Factors and Ergonomics Society Annual Meeting 1988年第19期32卷 1329 - 1333页

作者： Denise L. Wilson Gilbert G. Kuperman Eric G. Ramsey William A. Perez Human Engineering Division Harry G. Armstrong Aerospace Medical Research Laboratory Wright-Patterson Air Force Base Ohio 45433-6573 Human Engineering Program Office Systems Research Laboratories Inc. Dayton Ohio 45440

The objective of this research was to demonstrate the validity of signal detection theory to the assessment (visual discrimination) of displayed color symbology. The area of application of the research results is in the design specification of color coded symbology to be overlayed on moving map, situational awareness displays.A symbol detection experiment was designed to determine how far apart, in CIE/UCS color space, symbol and background color must be in order for observers to detect that a symbol is present against the background. Six trained observers viewed a number of systematically varied symbol/background color combinations and were required to make one of six responses along a continuum from “symbol definitely present” to “symbol definitely not present”.The analyses of the d' and Beta signal detection measures yielded different patterns of results, suggesting that this paradigm was successful in separating the cognitive and sensory/perceptual factors associated with color-on-color target detection. In addition, the shape of the Receiver Operating Characteristic (ROC) curves indicated that the assumptions underlying the signal detection paradigm were met.

Hydrogen peroxide is used to sterilize packaging material intended for aseptic packaging. After sterilization is achieved, the hydrogen peroxide must be removed to satisfy the maximum permissible residual of 0.1 ppm, based on the contained volume of the aseptic package. A pilot plant scale system for sterilization of flat stock packaging material was used to identify some of the critical variables affecting removal of hydrogen peroxide. Flat stock material was exposed to hydrogen peroxide at 27 and 8S°C at concentrations of 30 and 40% weight/weight. The sterilant was applied by immersion and misting. Hot sterile air at 66, 149, and 204°C was used to heat and remove the hydrogen peroxide. Immersion in hydrogen peroxide at 27°C, with a concentration of 30% weight/ weight, and air drying at 149°C for 35 s, reduced the average residual for eight containers to 3.5 ppm. The lowest average residual (0.2 ppm) was observed when hydrogen peroxide was used at 27°C, with a concentration of 40% weight/weight, and drying air at 204°C was applied for 7 s. The critical variables were the effective temperature of the drying air, the temperature of the sterilant, and the residence time in the drying zone. © 1986 ASTM International. All rights reserved.
