Dynamic Impulse Calibration Of Sheet Loaded Explosive, William James Johnson

Physics & Astronomy ETDs

In the past, experimenters have used Sheet Loaded Explosive (SLE) to simulate the damage caused by x-rays to an ICBM as the result of a nuclear burst from an ABM. One of the attractive features of SLE is that it can also provide high impul3e levels for structural damage studies. Previous measurements of the usual shock parameters such as peak overpressure, ietonation velocity, and shock front definition with short time interval pressure transducers were not suitable for total impulse measurements. The High Explosive Impulse Responder (HEIR) was developed to fill the need for a simple, reliable and economical total impulse …

Structure And Fluctuations Of The Oh Airglow At 1.65 And 2.15 P., Lois M. Kieffaber

Physics & Astronomy ETDs

The structure and fluctuations of the infrared airglow were studied at 1.65 and 2.15 μ. The emission at 1.65 μ is due to the (5,3) and (6,4) rotation-vibration bands of the OH molecule, and the 2.15 μ emission is due to the (9 , 7) OH band. Observations were made at Capilla Peak Observatory, New Mexico, and Haleakala Observatory, Hawaii, using two scanning photometers, of apertures 12 and 24 inches, equipped with interference filters and lead sulphide cells as detectors. The photometers have fields of view of the order of one degree, permitting the resolution of very small-scale spatial structure.

A General Lr(K) Parser Building Algorithm, Thomas Joshua Sager

Mathematics & Statistics ETDs

The problem is to find an efficient algorithm that, given the productions of a context-free grammar G, will discover whether G is LR(k) for given k and if it is build an efficient parser for G . The algorithm is given in Section 8. It is essentially a synthesis of the best parts of Knuth's and DeRemer's algorithms. On simple LR(k) grarranars it yields a result equivalent to DeRemer's algorithm, and like Knuth's algorithm it will work on all LR(k) grammars.

A new precision gamma scanning system is described. The system is designed for the thorough, detailed, nondestructive characterization of irradiated fast reactor fuel pins. Gamma scanning data are given for failed fuel pin , transfer mechanisms of fission products, quantitative isotopic scan­ning, and differential burnup profiles.

The system consists of a scanning mechanism for the precise positioning (±0.001 in.) of the irradiated fuel pin, high density tungsten alloy collimators for defining the volume segment from which the gamma-ray spectra are collected, a large high resolution an anticoincidence detector assembly for resolving complex gamma-ray spectra, and a computer con­trolled data acquisition …

The Synthesis Of Pyrimidines And Condensed Pyridazines As Potential Antimetabolites, Judith A. Wagner

Chemistry and Chemical Biology ETDs

Interest in the compounds described by this thesis was first aroused in the early 1930's when a research team began to investigate the mass poisonings of the population in Indonesia. The cause of the poisonings seemed to be the foodstuffs which the people made for themselves from the abundant coconut. Two products in particular, Bongkrek and Semaji, made from coconut presscakes and grated coconut, were apparently the source of the toxic substance. When made under improper conditions, the toxic principle developed in an otherwise harmless food product. A compound was finally isolated and established as the toxic principle by …

Convergence Lattices, Armando Rosario Gingras

Mathematics & Statistics ETDs

This study is concerned with complete lattices in which order convergence coincides with topological convergence with respect to the order topology. Such lattices are termed convergence lattices. After a brief discussion of topology on lattices (Introduction), some preliminary results concerning order convergence and the order topology are presented (Section 1). Several theorems characterizing convergence lattices are presented in Section 2. There it is shown that every neighborhood of a point of a convergence lattice contains an interval that is also a neighborhood of the point. It is also shown that each complete chain, each arbitrary product of convergence lattices, and …

A Study Of Trace Metal Concentrations In Two Species Of Mytilus Along The Pacific Coast Of The United States., George Harry Fullas

Earth and Planetary Sciences ETDs

An investigation of iron, zinc, copper, and cadmium concentrations in Mytilus californianus and Mytilus edulis was conducted on specimens collected along the west coast of the United States. Animals and sea water were collected at six different areas and analyzed using an Atomic Absorption Spectrophotometer. Trace metal concentrations in the animals were influenced by the collection conditions of age, species, temperature, pollution, and metal relationships. Younger animals, of both species, contained higher concentrations of all the metals. Larger, or older animals, contained the smallest metal concentrations. Copper concentrations in the animals were higher in sea water with high copper content. …

Interstate Comparison Of Input-Output Coefficients., Massis Galestanzadeh

Economics ETDs

The methods of foretelling, planning for future, range from the mythological to the mathematical and now many are confident that some methods developed by economics are sufficiently established to predict future economic events in the course of economic development. In spite of well known fiascos associated with planning mistakes and economic predictions, the need for forecasts and plans has been increas­ing. One reason for this need is that individual and collective living requires considerable amount of planning over a wide range of activi­ties.

The aim of this study is to examine a well known practice of economic planning, namely, to …

Higher Education Enrollment Projection Model: A Description And Evaluation, David W. Weig

Economics ETDs

With the increasing number of problems impacting higher education today, several efforts have been undertaken at the national, state and institutional levels. All of these reactions to the growing problem situation usually result in increased information requirements. The ability to accurately project student enrollment is a requisite to proper planning, budgeting and management of higher education. The large growth rate of the 1960's has ceased and the current outlook for the 1980's is for slight enrollment declines. This situation makes the 1970's a most sensitive time for projecting enrollments. It is during these transitory times that many procedures and methods …

The Effects Of Individualized Instruction On Mathematics Achievement In Third Grade, Ann Wheeler Hurt

Special Education ETDs

This study was conducted to determine the effects of individualized instruction on mathematics achievement in the third grade. Hypotheses were that: (1) individualized instruction would result in greater mathematics achievement than group instruction in mathematics, and that (2) individualized instruction would result in greater interest in mathematics than group instruction in mathematics.

Forty third grade students from each of two geographically adjacent elementary schools were randomly selected to comprise the experimental and control groups. The Metropolitan Achievement Test, Elementary Arithmetic Form B, Otis-Lennon Mental Ability Test, Elementary Level I-Form J, and an interest questionnaire were administered to both groups. A …
