Craft Specialization And Exchange Among The Virgin Anasazi, James R. Allison

Faculty Publications

A large proportion of the culinary ceramics found on 11th century Anasazi sites in the Moapa Valley of Nevada were manufactured more that fifty miles to the east, in northwestern Arizona. This paper uses analyses of ceramics from sites in southeastern Nevada, northwestern Arizona, and southwestern Utah to more precisely define the regional distribution of these ceramics and to assess their degree of standardization in form and technology. Questions relating to the development of community specialization and interaction in egalitarian societies are--examined in light of these analyses.

“Names, Hypocoristic,” In Anchor Bible Dictionary, Dana M. Pike

Faculty Publications

A hypocoristicon is generally a single-element name resulting from the shortening of an originally longer one. Hebrew names and Semitic names in general, were often composed of two elements (or, as was often the case in Akkadian names and sometimes the case with West Semitic ones, three elements) which formed a nominal or verbal sentence.

Glottal Airflow And Electroglottographic Measures Of Vocal Function At Multiple Intensities, Christopher Dromey, Elaine T. Stathopouloss, Christine M. Sapienza

Faculty Publications

Summary: Ten normal female subjects produced syllables at 5 dB increments from soft to loud. The differentiated electroglottogram (dEGG) open and speed quotients were compared to similar quotients from the inverse-filtered airflow waveform. The latter were measured according to objective and subjective criteria. The data indicate that the open quotient from the airflow waveform decreased as the intensity increased. The dEGG open quotient did not demonstrate this trend. The speed quotient from airflow increased initially with vocal intensity and decreased again as the intensity ceiling was approached. The ratio of closing to opening slopes calculated from peaks in the dEGG …

Chemical Percolation Model For Devolatilization: Ii. Temperature And Heating Rate Effects On Product Yields, Thomas H. Fletcher, Alan R. Kerstein, Ronald J. Pugmire, David M. Grant

Faculty Publications

The chemical percolation devolatilization (CPD) model describes the devolatilization behavior of rapidly heated coal based on the chemical structure of the parent coal. Percolation lattice statistics are employed to describe the generation of tar precursors of finite size based on the number of cleaved labile bonds in the infinite lattice. The chemical percolation devolatilization model described here includes treatment of vapor-liquid equilibrium and a cross-linking mechanism. The cross-linking mechanism permits reattachment of metaplast to the infinite char matrix. A generalized vapor pressure correlation for high molecular weight hydrocarbons, such as coal tar, is proposed based on data from coal liquids. …

Chemical Structure Of Char In The Transition From Devolatilization To Combustion, Thomas H. Fletcher, Mark S. Solum, David M. Grant, Ronald J. Pugmire

Faculty Publications

Coal devolatilization experiments are generally conducted separately from char oxidation experiments, and the relationship between the chars generated in the two types of research is often ignored. However, char is one of the most important products of coal devolatilization and must be characterized as a function of temperature and heating rate in a manner similar to that for gaseous devolatilization products. The chemical structure of the parent coal directly affects devolatilization behavior. In this work, the chemical structure of chars from five coals of different rank are examined, and implications on char reactivity are discussed. Chars were obtained as a …

Learn Audit Selection Rules From Data: A Genetic Algorithms Approach, David P. Greene, Rayman D. Meservy, Stephen F. Smith

Faculty Publications

The construction of expert systems typically require the availability of expertise that can be modeled. However, there are many important problems where no expertise exists, yet there is a wealth of data indicating results in different situations. Machine learning algorithms attempt to discover rules which capture the regularities that exists in such data.

X-Ray Diode Using A Silicon Field Emission Photocathode, W. I. Karian, Larry V. Knight, David D. Allred, A. Reyes-Mena

Faculty Publications

We have produced arrays of 10,000 sharp p-type silicon points using an etch plus oxidation method. The points were used as electron emitters. No high vacuum cesiation or high temperature cleaning was needed to observe the electron emission. These are seen to be photosensitive sources of electrons at 200 K and 300 K. They were also used to produce AlKα x-rays. This constitutes the first use of etched, point arrays for generating electrons for x-ray sources.

Manufacturing Of Atomically Sharp Silicon Tips And Their Use As Photocathodes, W. I. Karian, Larry V. Knight, David D. Allred, A. Reyes-Mena

Faculty Publications

The discovery and understanding of the photoelectric effect led to the study of photoemissive materials fall into two major categories: classical photoemitters and negative-electron-affinity (NEA) materials. Classical photoemitters usually involve an alkali metal, a group-V element such as phosphorus, silver, and/or oxygen. An example is the Ag-O-Cs (S1) photoemitter. NEA photocathodes consist of a photoconductive single crystal semiconductor covered with a thin layer of cesium and oxygen. This layer lowers the work function of the photocathode. A dipole layer is formed at the surface, and band bending occurs. This lowers the effective work function. An example is the GaAs(CsO) photocathode …

Faculty Publications

The purpose of this study was to investigate the effect on student learning of different ways of structuring student practice of complex motor skills. Previous research indicated that students who practiced the volleyball set and serve with a four-step progression learned more than students who practiced only the final test for the same number of practice trials; the effect of motivation and practice focused on specific learning cues was unclear. The present study investigated the specific role of progression, refinement, and motivation in learning the volleyball set and serve. Ninth-grade students were randomly assigned to one of five groups: (a) …

Thermal Mathematical Modeling Of A Multicell Common Pressure Vessel Nickel-Hydrogen Battery, Junbom Kim, T. V. Nguyen, Ralph E. White

Faculty Publications

A two-dimensional and time-dependent thermal model of a multicell common pressure vessel (CPV) nickel-hydrogen battery was developed. A finite element solver called PDE/Protran was used to solve this model. The model was used to investigate the effects of various design parameters on the temperature profile within the cell. The results were used to help find a design that will yield an acceptable temperature gradient inside a multicell CPV nickel-hydrogen battery. Steady-state and unsteady-state cases with a constant heat generation rate and a time-dependent heat generation rate were solved.

Comparison Of Heat-Fin Materials And Design Of A Common-Pressure-Vessel Nickel-Hydrogen Battery, Junbom Kim, Ralph E. White

Faculty Publications

A two-dimensional, axisymmetric, and time-dependent thermal model was developed to study the temperature behavior of the cylindrically shaped common-pressure-vessel nickel-hydrogen cell. A differential-energy-balance equation was used as the governing equation. A finite-element software package called PDE/Protran was used to solve this model. Different materials such as copper, copper beryllium, silver, and sterling silver were compared as heat-fin materials. The heat-fin geometry (thickness and height) and spacing were tested to find a design that yielded an acceptable temperature gradient inside a nickel-hydrogen cell. Pulse heat-generation rates were tested and correlated with the time-dependent heat-generation cases.

Mathematical Modeling Of A Primary Zinc/Air Battery, Z. Mao, Ralph E. White

Faculty Publications

The mathematical model developed by Sunu and Bennion has been extended to include the separator, precipitation of both solid ZnO and K₂Zn(OH)₄, and the air electrode, and has been used to investigate the behavior of a primary Zn-Air battery with respect to battery design features. Predictions obtained from the model indicate that anode material utilizationis predominantly limited by depletion of the concentration of hydroxide ions. The effect of electrode thickness on anode material utilization is insignificant, whereas material loading per unit volume has a great effect on anode material utilization; a higher loading lowers both the …

Removal Of Mercury From Waste Water: Large-Scale Performance Of An Ion Exchange Process, James A. Ritter, J. P. Bibler

Faculty Publications

Duolite™ GT-73 ion exchange resin routinely reduces the mercury content of a waste water stream to less than the permitted level of 10 ppb. Effluent concentrations from the ion exchange facility (IEF) are consistently between 1 to 5 ppb, even though the feed contains a varying concentration of mercury (0.2 to 70 ppm). Two operational problems have been encountered at that facility, however. Firstly, the stated capacity of the resin for mercury was not being achieved. The abnormally low capacity was traced to analytical laboratory waste which was intermittently treated by the resin. That waste contained hydrochloric acid, stannous chloride, …

On The Relationship Between Circumscription And Well-Founded Semantics Of Logic Programs, Jianhua Chen

Faculty Publications

The relationship between 2-valued circumscription and well-founded semantics of normal and disjunctive logic programs is addressed. For normal programs, we derive conditions under which the well-founded model coincides with the intersection of 2-valued models of prioritized circumscription. For disjunctive programs, we show that the refined semantics by Chen and Kundu coincides with the semantics of prioritized circumscription.

Free Speech And School Governance In The Wake Of Hazelwood, Rosemary C. Salomone

Faculty Publications

(Excerpt)

The Supreme Court's 1988 decision in Hazelwood School District v. KuhImeier upholding public school officials' authority to censor material in a high school student newspaper sent immediate shock waves throughout the educational and legal communities. The Court's sweeping language in Hazelwood moved far beyond the narrow issue of school newspaper censorship. It even moved beyond the question of appropriate or acceptable speech in public secondary schools. It was clear that Hazelwood could have far-reaching consequences for student rights, school governance, and the scope of official authority to make curricular decisions that reflect the values of the local community.
