Submicrosecond simulation computer study program.

Circuit techniques and memory devices for use in implementing a submicrosecond simulation computer are either currently available or are expeced to become available within a short time. Saturated transistor circuits are preferred for general usage in the system over other faster and more complex techniques because of the reduction in complexity, lower power dissipation and more latitude in permissible tolerance variation. A basic three-memory system has been defined which provides up to 32,000 words of instruction storage, 16,000 words of data storage and 1,000 words of fast "scratch pad" storage. The bulk storage devices are expected to be composed of ferrite elements which may be sensed nondestructively at a two-megacycle rate. The 'scratch pad" device will utlize magnetic films which may be cycled at a four-megacycle rate."Behavioral Sciences Laboratory; 6570th Aerospace Medical Research Laboratories; Aerospace Medical; Division; Air Force Systems Command; Wright-Patterson Air Force Base, Ohio.""Prepared under contract no.

Tryout of a preliminary procedure for systematically designing performance aids. /

A procedure for designing performance aids was given a limited-scope tryout on a portion of the Atlas E system. No evidence was found to contradict the performance aid recommendations generated by the procedure. The major change made in the procedure as a result of the tryout is to require providing performance aids for every task in a system except for tasks in which use of an aid would result in too slow performance. Training programs in the auto-instructional format are recommended as a routine addition to the performance aids complement. Five specific aids are recommended for the Atlas E system. Three important research problems are suggested for future research on performance aids development."Two additional reports were prepared under this contract which was initiated in April 1960 and completed in December 1961: ASD TR 61-548, "Research problems in the design of performance aids", and ASD TR 61-549, "A Review of the literature on design of informational job performance aids."--Page i"This report was prespared in support of Project No. 1710, "Training, personnel, and psychological stress aspects of bioastronautics".

Data flow: the general problem and a cognitive model /

The purpose of this study was to determine the state-of-the-art in data flow and to formulate a data flow model. ... The mechanics of the model include a verbal representation method, a graphic representation method, and a calculus. The verbal and graphic aspects of the model facilitate the communication and conceptualization of functional relationships within a system and the functional similarity or dissimilarity between both systems and parts of the systems. The model calculus, based on formal logic, facilitates the analysis and perception of the functional strategies of the system."Project no. 1710, Task no. 1710004.""Prepared under contract no.

Literature review of near infrared attenuating media /

"The purposes of this review was to investigate the literature for near infrared absorbing or attenuating systems with an emphasis on those that allow transmission of visible wavelengths. The spectral range of interest, therefore, lies between C.4 to 5.O microns. The types of infrared attenuating systems investigated include inorganic and organic compounds and other optical methods; such as, the interference filters and Christiansen filters." -- page iii.[ASTIA document] AD 283443 from ( http://www.dtic.mil/).

Environmental pollution by missile propellants /

"The effects of 21 missile fuel components, in concentrations of 0, 1, 10, 100, and 1000 ppm, were determined on aquatic organisms goldfish and Daphnia) soil mcroflora (bacteria, actinomycetes, and fung), plants (squash, soybean, cotton, cowpea, and corn) and sois (leachabiity, runoff, and structure) . Some or all of the aquatic organisms died when exposed to 100 ppm of the tet chemicals. The same concentration of chemcals had no effect on the counts of soil microflora. three of the test samples may sterilize the soil of actinomycetes. A concentration of 1000 ppm of two of the compounds and two ionic species produced inhibtion of seeding germination. Three of the ionc components, when used as a soil drench at 100 ppm, produced toxc symptoms. When three of the test chemicals (gases) were used at 100 ppm as air pollutants, severe injury or death occurred in all species. Soil analyses were erratic and indicated further research on this problem. Future studies should include the concentration-time relationship of the toxic materials and the absorptive capacities of soil fractions for the test compounds." -- page iii."This study was initiated by the Biomedical Laboratory of the 6570th Aerospace Medical Research Laboratories, Aerospace Medical Division, Wright-Patterson Air Force Base, Ohio.
