Research on triplet states and photochromism( Book )

4 editions published between 1962 and 1964 in English and held by 4 WorldCat member libraries worldwide

The report describes research studies on the photochromic properties of the triplet states of aromatic compounds and their application to the problem of eye-protection against nuclear weapons. A flash photolysis apparatus with spectrographic recording was assembled and used to study a series o f 26 aromatic hydrocarbons. Triplet-triplet absorption spectra were found for 25 of the compounds. Techniques were developed for incorporating triplet compounds into plastic media. Apparatus for automatic spectrophotometric recording of T-T absorption in irradiated plastic specimens and for studying quantum yields and phosphorescence lifetimes were built. Theoretical studies were carried out on the possibility of increasing the quantum yield of triplet formation and the intensity of T-T absorption by chemical substitution. A theoretical evaluation was made of a model triplet state filter as an eye-protective device
LIQUID LASER RESEARCH( Book )

2 editions published in 1962 in English and held by 2 WorldCat member libraries worldwide

Results highly suggestive of laser action have been obtained for benzophenone and a chelate of terbium in rigid organic glasses at 77 K.A resonant laser cavity employing multiple-layer, dielectric-coated, confocal mirrors was constructed. This was used for the low-temperature glass studies. Extension of observations to liquid systems is a simple matter using the above cavity. A high power flash apparatus of 12,800 joule capacity was constructed for excitation purposes. A technique was developed for flashing lamps immersed in liquid nitrogen. Techniques were developed for incorporating aromatic compounds and chelates into plastic rods for laser evaluation. Lifetimes of aromatic compounds in plastics were measured. Rareearth ions and chelates were evaluated for potential laser action in liquid solutions and experimental studies were started. Novel ways of experimentally increasing quantum yields are under consideration. (Author)

The operational readiness of a system subject to a mixed maintenance policy( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

This report presents a model of a system subject to a mixed maintanance policy and derives equa tions which can be used to produce a numerical value for the availability of such a system. An example of a system subject to such a mixed main tenance policy is the Inertial Guidance System of the Atlas Weapon, which is monitored continuously at a given test level and checked out periodical ly at a higher test level. In addition, a dis cussion of the data requirements necessary to estimate the parameters of the model is presented. (Author)
Techniques for analysis of nonlinear attitude control systems for space vehicles. volume iv. references and bibliography( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

This four volume report was prepared in order to compile, describe, and apply available nonlinear analysis and design techniques for space vehicle attitude control systems and to outline additional areas of future effort to improve present analysis and design procedures. Each of the four volumes is relatively independent of the others. Volume I is a definition and description of the problems associated with the design of the space vehicle attitude control systems. Volume II treats in detail the principal techniques for the analysis of nonlinear control systems and shows the application of these techniques to specific attitude control system problems. Volume III discusses three general problems in space vehicle attitude control systems, (1) single axis on-off gas jet system design, (2) active attitude control system design for a spin-stabilized vehicle, and (3) the design of a control system for a satellite vehicle with reaction wheels and gas jets. Volume IV is a collection of references and bibliography with annotations and comments covering the spectrum of the study effort. (Author)
Shock spectrum measurements by Frank W Galbraith( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

A total of twelve reed gages were installed to measure displacement shock spectra resulting from the Project Gnome underground nuclear explosion. Seven of the gages were installed on the ground surface at four locations out to a distance of 3000 feet from surface zero. All of these gages yielded usable records. Four of the gages were installed in the floor of the Gnome tunnel at two locations. Those at the 1033-foot range gave valid records; those at the 900-foot range were not recovered after the test. The one gage located underground at the International Minerals and Chemical Corporation (IMCC) mine, some nine miles distant, did not record any motion. The plotted displacement spectra showed the expected results in that displacements and peak accelerations decreased with increasing slant range for the surface gages. The vertical spectra were higher than the corresponding horizontal radial spectra for the surface gages. For the gages in the Gnome tunnel, the horizontal radial spectrum was higher than the vertical spectrum. (Author)
The TRW two-station, on-line scientific computer by Glen Jacob Culler( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

This report describes the research and development of on-line techniques and their application to problem solving. For convenience, it is organized in several parts. Part 1 lists the published papers describing research problems solved in the course of this effort and summarizes the computational aspects of the multi-dimensional problem (a nonlinear diffusion equation) which received the most attention; the physical significance of this problem and a discussion of the results obtained is given in part 5. Part 2 contains a general description of the on-line system from the user's viewpoint, including some elementary examples of the 'constructive' aspects of on-line computing. In part 3 we have collected the on-line problem solving techniques developed in this program which are of general interest. These involve a blending of numerical and mathematical analysis somewhat different from that generally encountered in conventional computing, being best characterized as emphasizing a global rather than a local approach to problem formulation and solution. Part 4 constitutes a complete user's manual for the present system. It gives a detailed description of each of the basic programs. A general understanding of the on-line system can be obtained from part 2; parts 3 and 4 provide the detailed information needed to actually use this system. (Author)
Interplanetary matter: a bibliography 1963 supplement( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

This bibliography consists of 662 annotated references on asteroids, comets, meteorites, meteors, micrometeorites, noctilucent clouds, nonterrestrial dust, origin of the solar system, tektites, the zodiacal light, and related subjects. The majority of the items are those published in 1963 as well as those released in 1963 by DDC and NASA. A few earlier items not listed in previous editions of this bibliography are included. The abstracts are primarily those written by the individual authors. If an author does not include an abstract with his paper, one is prepared by the compiler from the text of the report using the author's words; if this is impractical, a brief summary statement or table of contents is provided.

Displacement Spectrum Measurements by M. V Barton( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

Twenty-one reed gages were installed for radial (horizontal) and vertical displacement shock spectrum measurements on the Hard Hat event. Thirteen gages were installed in the tunnel liner structures of Project 3.1. Seven gages were installed in the unlined access tunnel floor. One gage was installed on the surface at a radial distance of 1,340 feet from Hard Hat zero point. Damage in the drift nearest the detonation, although expected to be large, was so severe that the drift was not opened and gage recovery at that range was therefore impossible. Fifteen of the 21 gages installed were recovered and of these, 12 yielded usable records. The three gages which yielded no information were damaged by collapse or partial collapse of the tunnel and structures in which they were placed. (Author)

Parameter estimation for continuously monitored systems( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The determination of weapon system capability requires the estimation of certain system parameters such as equipment failure rate, personnel error propensity, and test coverage. This study is concerned with the feasibility of measuring these parameters for systems whose status is continuously monitored, such as is characteristic of certain portions of the Atlas weapon system. The investigation proceeds via the analysis of these system models, which successively reduce the restrictions as to possible system states, and formulas are derived for the specified parameters in each case.

Electromagnetic scattering from a spherical nonuniform medium. part ii. the radar cross section of a flare( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The radar cross section for scattering of electromagnetic waves by a plasma having an electron concentration proportional to 1/r squared is calculated. The exact solution is compared with the scalar approximation. It is found that the exact solution can be orders of magnitude smaller than any of the usual approximations. (Author)
Analytic performance prediction of ablating heat shields( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

Preliminary design estimates of ablating heat shield performance have been hampered by the lack of a closed form solution of transient heat conduction in a finite slab with a receding boundary. Several expressions have been generated by an inverse technique in which relatively standard solutions of transient conduction with fixed boundaries are examined and the locus of points at a given (ablation) temperature is followed as it proceeds rearward from the heated surface. The receding boundary is postulated to coincide with this constant temperature locus and the heat flux necessary to produce this is calculated. The analytic technique is applied to several cases involving triangular heat pulses and the results compared to a more exact digital computer program solution. The amount of material ablated and the thickness required to produce a given backface temperature are in agreement. Prediction of backface temperature is adequate for preliminary design. (Author)
Preliminary study of the viscous inviscid interaction in the laminar supersonic near wake( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

An attempt is made to determine in a simple way the nature of the interaction of merging supersonic shear layers with an external inviscid flow in the heat conducting laminar near wake. For this purpose, a solution of the two-dimensional boundary layer equations using a twomoment integral method is examined. Several sample calculations of base flow are given which enable an evaluation of the Chapman model of instantaneous recompression. Also, a comparison is made with the earlier solution of Lees and Reeves for the adiabatic case in which Stewartson profiles were used. Despite the simplicity of the present analysis, good agreement is found for axis velocity ratios greater than -0.1; it is therefore concluded that the solution is not sensitive to assumed profile shape near and beyond the stagnation point. However, the importance of an adequate profile representation for the flow near the body is clear and the extension of the methods used herein to incorporate this improvement is discussed
Electromagnetic scattering from aspherical non-uniform medium part i. general theory( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The scattering of electromagnetic waves by a spherically symmetric continuous dielectric is examined. Two distinct methods for calculating the scattering amplitude are derived. It is shown that the scalar approximation is, in general, extremely poor. The radar cross section, is discussed in some detail. (Author)
RESEARCH ON CHARGED COLLOID GENERATION( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The experimental research involved in the electrical dispersion of liquids technique of generating a charged colloid beam is described. Charge/mass ratios were obtained by the use of a quadrupole focusing mass spectrometer during the single capillary tube stage of the work. When multiple needles were operated in parallel to increase the beam current, time-of-flight measurements replaced the quadrupole spectrometer. Data are presented both for the results obtained with single capillary tube operation and for the operation of many tubes in parallel. (Author)
