Shape competition and alignment processes in light Au and Pt nuclei
Calculations are presented and data are reviewed on the properties of the high-j states in the light Au nuclei. Both prolate and oblate structures are observed in this region. It is found that the collective model describes well the band-head and the high-spin properties of the h/sub 9/2/ and i/sub 13/2/ proton states, without resort to an ''intruder state'' phenomenology.

The Development and Evaluation of a Forecasting System that Incorporates ARIMA Modeling with Autoregression and Exponential Smoothing
This research was designed to develop and evaluate an automated alternative to the Box-Jenkins method of forecasting. The study involved two major phases. The first phase was the formulation of an automated ARIMA method; the second was the combination of forecasts from the automated ARIMA with forecasts from two other automated methods, the Holt-Winters method and the Stepwise Autoregressive method. The development of the automated ARIMA, based on a decision criterion suggested by Akaike, borrows heavily from the work of Ang, Chuaa and Fatema. Seasonality and small data set handling were some of the modifications made to the original method to make it suitable for use with a broad range of time series. Forecasts were combined by means of both the simple average and a weighted averaging scheme. Empirical and generated data were employed to perform the forecasting evaluation. The 111 sets of empirical data came from the M-Competition. The twenty-one sets of generated data arose from ARIMA models that Box, Taio and Pack analyzed using the Box-Jenkins method. To compare the forecasting abilities of the Box-Jenkins and the automated ARIMA alone and in combination with the other two methods, two accuracy measures were used. These measures, which are free …

Thus Spake Bosch
Access:
Use of this item is restricted to the UNT Community
"Multiplicity of Unity" or "Unity of Multiplicity" are pure illusions and mystifications. Nothing relates to anything, nothing can be deduced from anything, there are no causes nor effects. Neither there is a world of ideas, monads and essence, therefore each reduction, even eidetic, is just a replacement of objects-- or better --words which seem to be especially developed for this useless game. Anything may precede anything, anything may follow anything, and there is nothing which might not coexist with anything else. The ordering function of time is another illusion and oversimplification. The same applies to necessity. After all, "impossibility" is a common thing, indeed. There remains one question, however: what does the world seen from the top of Palace of Culture and Science in Warsaw have in common with the world seen from the top of Empire State Building? Nothing. And this is a right answer. I can not miss an opportunity of expressing my deepest gratitude to John Chowning for his human voice synthesis, to David Jaffe for his pluck instruments synthesis, to Bill Schottstaedt for his strings and for myself for the remainder. Thus Spake Bosch was composed in March 1985, premiered in Warsaw on April 11, 1985 …

Reaction mechanisms in the radiolysis of peptides, polypeptides and proteins
The purpose of this review is to bring together and to correlate the wide variety of experimental studies that provide information on the reaction products and reaction mechanisms involved in the radiolysis of peptides, polypeptides and proteins (including chromosomal proteins) in both aqueous and solid-state systems. The comparative radiation chemistry of these systems is developed in terms of specific reactions of the peptide main-chain and the aliphatic, aromatic-unsaturated and sulfur-containing side-chains. Information obtained with the various experimental techniques of product analysis, competition kinetics, spin-trapping, pulse radiolysis and ESR spectroscopy is included. 147 refs.

Surface segregation during irradiation
Gibbsian adsorption is known to alter the surface composition of many alloys. During irradiation, four additional processes that affect the near-surface alloy composition become operative: preferential sputtering, displacement mixing, radiation-enhanced diffusion and radiation-induced segregation. Because of the mutual competition of these five processes, near-surface compositional changes in an irradiation environment can be extremely complex. Although ion-beam induced surface compositional changes were noted as long as fifty years ago, it is only during the past several years that individual mechanisms have been clearly identified. In this paper, a simple physical description of each of the processes is given, and selected examples of recent important progress are discussed. With the notable exception of preferential sputtering, it is shown that a reasonable qualitative understanding of the relative contributions from the individual processes under various irradiation conditions has been attained. However, considerably more effort will be required before a quantitative, predictive capability can be achieved. 29 refs., 8 figs.

An Investigation of the Career Realities and Occupational Concerns of Selected Professional Performing Musicians
The purpose was to investigate the career realities and occupational concerns of successful full-time performing instrumentalists. Four research problems were formulated; (1) the establishment of a demographic profile of musicians who perceived themselves successful; (2) the determination of the musicians' career realities; (3) the determination of the musicians' occupational concerns; and (4) a comparison of the relationship of the demographic profile to the career realities and occupational concerns. A pilot study was used to develop a questionnaire and an interview schedule. The sample for the main study was chosen by the questionnaire and consisted of twenty musicians, five each in the musical categories of jazz, classical, commercial and pop. To resolve research problem one, the questionnaire also collected general demographic data. Research problems two and three were fulfilled by an interview schedule based upon career realities and occupational concerns cited in previous sociological studies. The realities and concerns were either confirmed or refuted by each interviewee. The career realities were role conflict, career contingencies, musical labels, life style, hierarchies, audience relationships and environment. The occupational concerns were mobility, status, entrapment, personal contacts, dependency, security, competition, economic issues, working conditions, travel requirements, appearance, management control, auditions, maintenance of skills and training …

Analysis of transient fission gas release and swelling in oxide fuel
Calculations of fission-gas behavior have been carried out with an updated version of the FRAS3 code for the FGR-40 series of transient tests of irradiated PNL-10 fuel. This same series of tests was used in an earlier evaluation study with a preliminay version of the code. While that study provided positive support for the modeling approach, it also indicated deficiencies in some areas. Although a number of improvements have been implemented in the current version of the code, this study examines the effect of an explicit treatment of bubble growth within the grains, including the effect of vacancy depletion caused by the competition of overpressured bubbles for available vacancies. The result is a reduction by as much as 90% in the predicted swelling, accompanied by an increase in transfer of gas from the grains to boundaries. Both swelling and gas release predictions are brought into much better agreement with the observed values.

Two-dimensional diffusion limited system for cell growth
A new cell system, the ''sandwich'' system, was developed to supplement multicellular spheroids as tumor analogues. Sandwiches allow new experimental approaches to questions of diffusion, cell cycle effects and radiation resistance in tumors. In this thesis the method for setting up sandwiches is described both theoretically and experimentally followed by its use in x-ray irradiation studies. In the sandwich system, cells are grown in a narrow gap between two glass slides. Where nutrients and waste products can move into or out of the local environment of the cells only by diffusing through the narrow gap between the slides. Due to the competition between cells, self-created gradients of nutrients and metabolic products are set up resulting in a layer of cells which resembles a living spheroid cross section. Unlike the cells of the spheroid, however, cells in all regions of the sandwich are visible. Therefore, the relative sizes of the regions and their time-dependent growth can be monitored visually without fixation or sectioning. The oxygen and nutrient gradients can be ''turned off'' at any time without disrupting the spatial arrangement of the cells by removing the top slide of the assembly and subsequently turned back on if desired. Removal of the …

The Other Shape
Access:
Use of this item is restricted to the UNT Community
The Other Shape is largely based on contradictions. Between the short and the long, for example. The short sound and the resonant. The dry and the reverberated, or the lengthened. The continuity of silence or holding, opposed to the brutal and ephemeral explosion of percussive sounds. As in many other plays, this dialectic has led me to a typically segmented and punctuated, simple and bare form. For its realization, I had recourse to many programs of composition, acting either at the level of whole sections, the setting up of frameworks, the development of rhythmic patterns, the detailed specification of stochastic structures, or even of the arrangement of the components of certain complex sounds and textures of the band, and the direct synthesis of some sounds. In this piece, the percussionist and the band are in situation essentially complementary, in a naturally concerting spirit. The band develops and amplifies the world of percussion: rhythmic and spatial extensions and multiplications, of timbres, durations and resonances, establishing relationships of convergence, dialogue or opposition. It remains very connected to the instrumental domain, but sometimes, when it ventures the most in its role, overflows towards other sound regions and asserts its independence. The vast majority …

Actinide production in /sup 136/Xe bombardments of /sup 249/Cf
The production cross sections for the actinide products from /sup 136/Xe bombardments of /sup 249/Cf at energies 1.02, 1.09, and 1.16 times the Coulomb barrier were determined. Fractions of the individual actinide elements were chemically separated from recoil catcher foils. The production cross sections of the actinide products were determined by measuring the radiations emitted from the nuclides within the chemical fractions. The chemical separation techniques used in this work are described in detail, and a description of the data analysis procedure is included. The actinide production cross section distributions from these /sup 136/Xe + /sup 249/Cf bombardments are compared with the production cross section distributions from other heavy ion bombardments of actinide targets, with emphasis on the comparison with the /sup 136/Xe + /sup 248/Cm reaction. A technique for modeling the final actinide cross section distributions has been developed and is presented. In this model, the initial (before deexcitation) cross section distribution with respect to the separation energy of a dinuclear complex and with respect to the Z of the target-like fragment is given by an empirical procedure. It is then assumed that the N/Z equilibration in the dinuclear complex occurs by the transfer of neutrons between the two …

The Decision-Making Process in Commercial Motor Carrier Selection
This study is designed to gain a better understanding of the decision process of freight shippers who use commercial truckers. Pursuant to this study, it is possible to gather some insights into the phenomenon of the selection of a trucking company to transport goods. Planning is essential to the attainment of goals in any type of firm, and that is especially true in the volatile environment of commercial trucking. Development of the external environment of trucking is prerequisite to the planning process and essential to the attainment of goals. The external environment of a trucking firm is generally represented by economic, social, and political influences, which extend specifically to the nature and tendencies of its markets, i.e., the shippers.
