User's guide for atmospheric carbon monoxide transport model

In the winter months of Fairbanks, Alaska, a highly stable air temperature inversion creates high levels of carbon monoxide (CO) concentrations. As an aid to understanding this problem, a CO transport computer model has been created which provides a useful tool when used in conjunction with other measurement and analytic studies of traffic, meteorology, emissions control, zoning, and parking management. The model is completely documented and illustrated with several examples. Named ACOSP (Atmospheric CO Simulation Program), it predicts expected CO concentrations within a specific geographic area for a defined set of CO sources. At the present time, the model is programmed to consider automobile emissions as the major CO source and may include estimates of stationary sources. The model is coded for computer solution in the FORTRAN programming language and uses the finite-element method of numerical solution of the basic convective-diffusion equations. Although it has a potential for real-time analysis and control, at the present time the model will be most valuable for investigating and understanding the physical processes which are responsible for high CO levels and for testing remedial control measures at high speed and low cost

Using Intelligent Simulation to Enhance Human Performance in Aircraft Maintenance

Human factors research and development investigates the capabilities and limitations of the human within a system. Of the many variables affecting human performance in the aviation maintenance system, training is among the most important. The advent of advanced technology hardware and software has created intelligent training simulations. This paper describes one advanced technology training system under development for the Federal Aviation Administration

ESTIMATES OF POTENTIAL RETURNS FROM ADDED RESEARCH BUDGET FOR THE LAND GRANT UNIVERSITIES

This paper briefly reviews approaches that have been used to assess returns to U.S. agricultural research and explains the usefulness of benefit cost analysis in such evaluations. Benefit-cost analysis is applied to the Land Grant Universities federal budget requests for additional funds for corn and soybean research in the North Central region. Finally, the problems involved in applying a similar analysis to livestock and rural development research are discussedResearch and Development/Tech Change/Emerging Technologies,

The development, optimisation and testing of an unmanned parafoil launch system

Includes summary.Includes bibliographical references (leaves 70-73).Parafoils have been used in various aerospace, military and sport applications to return both personnel and payloads safely to the ground. Deflection of the trailing edge flaps by means of control lines allows for turn rates of up to 60° per second, which provides superior controllability when compared to conventional round parachutes. This steering ability has led to the development of autonomous control systems that are able to navigate a payload to land in close proximity to a designated landing site. In order to develop an autonomous navigation system a suitable dynamic model of the parafoil with suspended payload is required to determine the parameters and characteristics of the system in free flight. Flexible ram-air inflated parafoils display high sensitivity to atmospheric disturbances which complicates the comparison of measured flight-dynamic data to theoretical models in an open air free flight test. In order to improve the quality of results in studying the flight dynamics of an unmanned parafoil system in free flight, controlled conditions and a repeatable flight path are required to perform data analysis for various trim configurations. This leads to the requirement of a launching system that ensures consistent inflation of the canopy and repeatable launch velocities for various canopy and payload configurations

Presidential Address - The Social Service of Science

The extent to which society may be considered as an organism is still, I understand, a matter of controversy with sociologists. But without awaiting its adjudication, we may surely make use of a simile as ancient as that of the Apostle who spoke of individual Christians as members of one body, or as that of the wise old Roman, who taught the mutinous plebs the parable of the body politic, all of whose members were nourished by the well-fed patrician belly, and consider together this evening the social function of science in the body social
