This work deals with the investigation of the combustion of solid, liquid, and water-filled systems in a field of inertial forces. The tests were conducted on a centrifuge with a radius of 4.5 cm at accelerations up to 2000 g. The samples were burned in a closed space at pressures up to 150 atm(tech.). The time of burning was determined by a pressure oscillogram. The solid composition investigated contained 15% rubber, 15% aluminum (particle dimensions up to 10 micrometers, and 70% ammonium...

The infrared absorption by samples of H2O and H2O + N2 has been studied in three spectral regions, 1630-2290/cm, 1250-1445/cm and 430-822/cm. The samples cover a wide range of path lengths and pressures with temperatures up to 433 K. The emphasis had been on the continuum absorption in several narrow spectral intervals where most of the absorption results from lines centered more than 1/cm from the point of observation. Absorption by the distant wings of N2-broadened H2O lines is less relative...

Many salts of ammonia and hydrazone (for example, perchlorates, nitrates) are capable of self-contained combustion. A characteristic feature of these compounds is the rather high rate of reaction of the decomposition in the condensed phase and the capacity for vaporization.

Chemical releases of barium or lithium may modify the wave particle interactions in the magnetosphere such that the phenomena can be better investigated and may lead to techniques for producing desired wave particle interactions.

The measured backscattering characteristics of two metallic right circular cones, with and without absorbing pads on their bases, are shown in 328 patterns. The absorber pads were used to reduce second order diffraction across the base of the cones. Measurements were carried out at closely spaced frequencies from 8.0 to 12.0 GHz, for both horizontal and vertical polarizations, using a CW cancellation method.

The report describes the activities and accomplishments associated with the two major technical tasks on this project. The first task is the development of a linearly polarized two-dimensional phased array which is well matched simultaneously over a large scan angle range and over an octave bandwidth. The second task is to extend the impedance matching of the linearly polarized element to an arbitrarily polarized element for wide-angle scanning and wide tunable bandwidth.

The capacitive bolometer effect must be described in terms of the d-c capacitance c(d) = Q/V. The effect can also be interpreted as an induced pyroelectric effect. The noise in d-c biased capacitive bolometers must be interpreted as polarization noise, enhanced by the d-c field. The molecular field theory of ferroelectricity has been applied to the evaluation of p/epsilon and p/epsilon sup 1/2 shows the right order of magnitude.

A statistical procedure for determining the resolution to be used in spectral-matrix estimation is needed for the exploratory analysis of non- stationary multiple time series. The procedure accomplished this by creating periodograms for a frequency-time interval and then successively dividing this interval into subintervals. At each step, the division is chosen by comparing spectral matrices using the largest-root statistic. This multiple-decision rule is shown to be consistent. Small-sample...

The report presents a study of problems associated with using the Fourier transform restoration procedure to restore atmospherically degraded images of high flying objects. The study is divided into two parts, an examination of the restoration procedure and an estimate of atmospheric effects. The two parts were joined by choosing a model which assumes the phase front of an atmospherically degraded light wave can be represented as a truncated polynomial series. Preliminary results indicate that...

The report covers the period from 1 January to 30 June 1973, and describes the tasks of remote monitoring and field maintenance of NORSAR. The corrective maintenance of NORSAR during the first half of 1973 has been of limited extent. A preventive maintenance program for the SP seismograph amplifiers and the WHVs, and a couple of investigations to reduce the maintenance load of certain channel units, were initiated in the period. In general, the different parts of the array field instrumentation...

The report covers the operation of the NORSAR system in the period 1 Jan - 30 Jun 1973. Array monitoring and control and associated field maintenance activities are, according to contract, covered in a special report. No unusual or major problems were encountered in the period. Computer and other equipment still shows reasonably good stability. A somewhat high communications line outrage was experienced, causing degraded performance or data loss for shorter periods.

The paper challenges the idea that the assured destruction capability of American nuclear deterrence must focus on enemy population centers. As an alternative it urges a countercombatant targeting capability and intention, directed to depriving an enemy of the ability to maintain internal security and security against hostile neighboring states, even though the latter might initially have been much weaker than itself. The specific targets would thus be internal security forces, military...

The paper consists of two major sections: (1) A theoretical discussion of the political entrepreneur and the potentially different behavior of leadership in polyarchies or non-polyarchies; and (2) an empirical section which attempts to test the hypotheses about political entrepreneurship-- particularly as they apply to different comparative political systems and most importantly (as it turned out) different sizes of bureaucratic systems.

Two computer simulation models allow probability of target detection as a function of sonar range to be used as a measure of effectiveness.

These parameters are target speed,...

Synthesis methods that yield the required converters, uncompensated or compensated, are presented. Lastly, the performance of several of the constructed antenna systems are compared with that of a 12 foot whip.

Linear FM-modulation was achieved by sweeping the drive frequency from 100 to 500 MHz in linear fashion. The optical beam coupled from the resonator represented a suppressed-carrier- double-sideband-modulated. signal. The sidebands are chirped in opposite spectral directions as the modulation is swept through the chirp range. By placing the optical carrier in the wing of the P(20)...

The four water disturbances considered are surface waves, internal waves, turbulence, and vertical gradients of currents.

The quasi-periodic variations cause difficulty in averaging and sampling the water speed for use in...
