The structure of ionizing shock waves and their induced boundary layers in argon have been studied experimentally in the UTIAS 4 inch x 7 inch hypervelocity shock tube using dual-wavelength interferometry. The relaxation lengths and transitions of shocks of Mach numbers 16.5 and 13.5 for initial gas pressures of about 5 torr have been measured at 2cm and 8cm, respectively. The transition profiles and relaxation lengths are in reasonably good agreement with analysis.

The cognitive model of what is learned during flying training presents an alternative to the familiar concept of flying skill as hand-eye coordination. The model relates the growth of pilot ability to the student's increasingly refined cognitive discriminations about his flying performances made possible by his improved familiarity with the phenomena of flight gained practicing aircraft control tasks.

The seismicity and earthquake mechanism of the Atlantic Ocean north of Iceland is discussed. It is demonstrated that the surface wave method can be extended to small earthquakes using known fault plane solutions in the region as reference events. The outcome of these studies - Rayleigh and Love dispersion, attenuation, focal depth, seismic moment and focal mechanism - can be useful quantities for discussing the tectonics of the North Atlantic.

Humans perform vast quantities of spontaneous, subconscious computation in order to understand even the simplest language utterances. The computation is principally meaning-based. With syntax and traditional semantics playing insignificant roles. This thesis supports this conjecture by synthesis of a theory and computer program which account for many aspects of language behavior in humans. It is a theory of language and memory.

The agglomeration of liquid alumina particles takes place in the convergent region and at the throat of the nozzle; it leads to an increase of performance losses related to the velocity and temperature differences between the condensed and gaseous phases. The problem is first schematized; then the fundamental equations of the problem are established that give the evolution of the distribution law of the particle population, and of the variables induced by the collisions.

A study was made concerning the statistical theory of light propagation in a turbulent medium. A parabolic equation which was examined was only valid when back scattering could be disregarded. The theory proposed uses the small value of the longitudinal scale of heterogeneities, as compared with other longitudinal scales of the problem. Many difficulties encountered in the range of strong fluctuations are eliminated in the new theory.

The analysis is based on the theories of liquid adhesives, the fracture of liquids and the concepts of fracture mechanics. It is shown that boundary separation rather than boundary sliding is the step that controls the deformation rate. Using this principal result, it is shown that the deformation behavior of a polycrystalline material with a viscous boundary...

A system is described which automatically chooses representations for high-level information structures, such as sets, sequences, and relations for a given computer program. Representations are picked from a fixed library of low- level data structures including linked-lists, binary trees and hash tables. The representations are chosen by attempting to minimize the predicted space-time integral of the user's program execution. Predictions are based upon statistics of information structure use...

An analysis of the climatic changes from the 1921-50 period to the following 1951-60 and 1961-70 decades showed moderate synchronism in the annual and December-May changes of the circulation of the two regions as revealed by the intensity and position of the No. Pacific (Aleutian) and No. Atlantic (Icelandic) Lows. A filling-in and southwestward retreat of the Aleutian Low in the 1950's and 1960's in relation to the 1921-50 period was paralleled by a filling-in of the Icelandic Low in the same...

An investigation has been conducted into the chemical aging of ANB-3066 Minuteman propellant for the purpose of establishing means to employ accelerated surveillance data for predicting useful life under silo storage conditions (70 plus or minus 10F, inert atmosphere). At intervals during aging, chemical analyses (primarily infrared) were performed and physical tests were conducted, the latter consisting of gel content, degree of swell, creep compliance, dilatation, and crack propagation. The...

Preliminary analysis of long-period recordings of five central California earthquakes indicates that the long-period of the observed spectra may be influenced by the recording site; that the spectrum for small earthquakes tends to be somewhat peaked; and that a Q of 100 seems to be appropriate for the area of interest. Work in Nevada has led to selection of a site for a continuation of the near-field experiment. The area selected is north of the Mina area and south of Fairview Peak. Stations...

Solid fuel propellants seeded with copper powder have been examined as an example of chemical generation of the copper vapor in a copper-vapor laser that has the potential of generating a visible output (510.6 nm) with high efficiency. Chemical generation of the copper vapor is the only approach capable of producing an overall electrical efficiency of 10 percent in a flowing copper- vapor laser. The effect of Ar, N2, CO2, CO, H2, and H2O as additive gases on the laser's performance has been...

The objective of the Joint Experiment on Earthquake Source Spectra is to improve our ability to distinguish between the explosive and tectonic energy releases in the magnitude range 3 = or M = or 5. Recording the near-field strong ground motion will help in the more accurate determinations of the earthquake source time function and thus will improve the reliability of the near- and far-field spectra which are still the basic tools in detection work.

An accurate and efficient method has been developed for predicting transition from laminar to turbulent flow, based upon a phenomenological model originally devised for fully turbulent flows. The model is modified to account for low Reynolds number phenomena and is used to make a priori transition predictions. Primary emphasis focuses upon blunt-body flows; predictions are also made for constant-pressure boundary-layer flows to provide as broad a data base as possible to assess model accuracy.

A procedure for solving binomial probability problems was taught in a three-part booklet that emphasized calculating with the formula (Sequence F) or that emphasized that the meanings of the variables in the formula (Group G). A multi-leveled transfer posttest was administered after S had read either one, two or all three parts of his instructional booklet, and the amount of stress during testing was varied. The results indicated how a clear pattern of treatment vs. posttest interaction (TPI)...

A proposed solution to the mixed event problem in nuclear seismic discrimination, termed the 'ellipticity filter', is cast in the form of a solution of the superposition equations defining the signals from a three- component seismometer station. Two cases of superposed signals are considered: Rayleigh with Rayleigh; Rayleigh with Love. Using the ellipticity constraint at the seismometer station site, the superposition equations defining each case are solved in closed form to yield the unknown...

The problem of vehicle mobility is a complex one in that a rigorous analytical treatment of the mechanics involved between vehicle characteristics, such as geometry, size, and driving forces, and the properties and responses of soil that supports a moving vehicle has not been developed. In general, immobilization problems occur as a result of the loss of or excessive demand for traction created by a combination of sinkage, slope, forces applied, obstacles, and environmental conditions....

CS-1 applied to branches of six woody species caused greatest damage when plants were in immature foliage. Four herbaceous species grown in soil with incorporated CS-1 showed maximum seedling damage when agent applications were made within four weeks prior to planting. Greenhouse screening tests on 29 woody and 41 herbaceous species at dosages of 5.6 and 28 kg/ha showed the herbaceous group to be more susceptible to foliar damage than woody species and to exhibit a greater range of variability...

The theory of inertial impaction of particles on cylinders has been analyzed and used to develop standard inertial impaction efficiency curves. Unique exponential functions have been generated by a digital computer that accurately fit the inertial impaction theory with a maximum relative error of less than 1%. Interpolative routines have been adapted for the computer program to obtain inertial impaction efficiency predictions for all inertial parameter and velocity field scaling parameter...

Processing methods to produce zinc and manganese phosphate coatings with greater heat and corrosion resistance on ferrous items were investigated. Conventional phosphating solutions enriched with salts of the alpha-reactive- carboxylic-acids, such as manganese salts of citric, tartaric, and gluconic acids were processed under steam and atmospheric pressure. Manganese carbonate and manganese dihydrogen phosphate were added to control the free and total acids. Evaluations were made of the coating...

The study revealed advantages and limitations of the ionitriding process, and documented the production sequences required for the case-hardening of AlSl 4140 and Nitralloy 135M steels. Determination of processing criteria included cleaning, loading, selective case-hardening, treatment times and temperatures, and geometric considerations. The production sequence was established for four weapon components presently manufactured at Rock Island Arsenal. Evaluation of processing times and quality...

SLIP, an acronym for Symmetric List Processor, is a list processing system which carries a forward and backward link as well as a datum. It is symmetric in the sense that lists do not have a preferred orientation; operations which can be carried out on the top of a list can be as easily carried out on the bottom of the list. List processing languages are formal mathematical languages and have been used in symbolic processing in calculus, circuit theory, mathematical logic, artificial...

The program FNFIT uses both steepest gradient, and chi-square minimization searches to fit a user-chosen, arbitrary (including nonlinear) function to a set of input data points. Options are included to allow control of the search for particularly pathological functions, making the program quite versatile. However, the program can also be run without the options, providing an easy-to-learn-and-use tool for the pedestrian.

Two brands of commercially prepared fully cooked chicken were investigated. The chicken was stored at -12C., -18C. and -28C. and withdrawn for evaluation at 0, 3, 6 and 9 months. The chicken was heat conditioned for serving by heating either in a convection oven or in a deep fat fryer. Both 10 member technological and 30 member consumer panels were used to evaluate the product. The consumer panel evaluated the chicken as part of a luncheon menu. Analysis of panel scores indicated that the brand...

Stress intensity factor data from a boundary value collocation method are used to determine the K calibration for a proposed standard C-shaped specimen for fracture toughness testing. The standard specimen can be readily used with hollow cylinders which have outer-to-inner diameter ratios between 1.2 and 3.0. The K calibration is described in a polynomial form similar to that used with the ASTM standard compact specimen but with an additional term dependent on diameter ratio. Stress intensity...
