Data Flow Program Graphs, Alan L. Davis, Robert M. Keller

All HMC Faculty Publications and Research

Data flow languages form a subclass of the languages which are based primarily upon function application (i.e., applicative languages). By data flow language we mean any applicative language based entirely upon the notion of data flowing from one function entity to another or any language that directly supports such flowing. This flow concept gives data flow languages the advantage of allowing program definitions to be represented exclusively by graphs. Graphical representations and their applications are the subject of this article.

Magneto-Hall And Magnetoresistance Coefficients In Semiconductors With Mixed Conductivity, David C. Look

Physics Faculty Publications

Magneto-Hall and magnetoresistance formulas, correct to order B², are derived for the case in which both single-carrier and mixed-carrier effects are important. Also, a new magneto-Hall coefficient Is Presented: β=‹π⁴›‹π›/‹π²›³ - 1. Values of β for various scattering mechanisms are calculated and compared with experiment

The Chromospheres Of Classical Cepheids. I. Low Resolution Iue Spectra, Edward G. Schmidt, Sidney B. Parsons

Edward Schmidt Publications

We have undertaken a program to study the behavior of chromospheres in classical Cepheids using both ground-based and satellite-based observations. Five stars, δ Cep, η Aql, β Dor, ζ Gem, and l Car, have been included, and where possible the various types of data have been obtained simultaneously. The first part of this investigation concerns low dispersion spectra from the IUE satellite. Fine error sensor (FES) magnitudes are presented for the five Cepheids and, in the case of one, η Aql, are used to re-discuss the period. The "artificial viscosity dip" predicted by some theoretical calculations may be present in …

Polarization Of Fluorescence Radiation Subsequent To Inner-Shell Photoionization: Ls-Coupling Formulas, Anthony F. Starace

Anthony F. Starace Publications

The polarization and angular distribution of fluorescence radiation subsequent to inner-shell photoionization in atoms are presented here in the important special case that dynamic amplitudes are calculated in LS coupling taking full account of anisotropic electron-ion interactions. The resulting formulas require for their evaluation no more dynamical information than is usually obtained in an LS-coupling calculation of the photoionization cross section. Exact geometrical relationships which are obscured in more general treatments become apparent in an LS-coupling formulation. Thus it is shown that in LS coupling the fluorescence resulting from photoionization of an s subshell in an atom having …

A Hidden-Line Algorithm For Hyperspace, Robert P. Burton, David R. Smith

Faculty Publications

An object-space hidden-line algorithm for higher-dimensional scenes has been designed and implemented. Scenes consist of convex hulls of any dimension, each of which is compared against the edges of all convex hulls not eliminated by a hyperdimensional clipper, a depth test after sorting and a minimax text. Hidden and visible elements are determined in accordance with the dimensionality of the selected viewing hyperspace. When shape alone is the attribute of interest, hidden-line elimination need be performed only in that hyperspace. The algorithm is of value in the production of shadows of hyperdimensional models, including but not limited to four-dimensional space-time …

A New Computer-Oriented Approach To Molecular Mechanics, Donald Greenspan

Mathematics Technical Papers

A new dynamical theory for atomic and molecular dynamics is formulated and discussed. The associated nonlinear differential system is derived from general atomic and molecular stability properties and from aspects of modern particle theory, especially as it relates to the structure of the electron. Computer experiments are described for developing a new model of the water molecule.

Hydrocarbon Fuel Chemistry : Sediment Water Interaction, William G. Macintyre, C. L. Smith, P. O. Defur, C. W. Su

Reports

The objective of this program was to determine the effect of sediments on aqueous solutions of selected United States Air Force (USAF} hydrocarbon fuels. Effects of sediment type, organic carbon content, pH, temperature and salinity on interaction of dissolved hydrocarbons with sediment were studied. The results of this work can be used to estimate the role of sediment hydrocarbon interaction terms in fate models of aqueous systems, such as the Environmental Protection Agency "EXAMS" model.

A Geochemical Study Of The Rhododendron And Dalles Formations In The Area Of Mount Hood, Oregon, Marshall W. Gannett

Dissertations and Theses

The Miocene Rhododendron and Dalles Formations in the Mount Hood area are accumulations of chiefly pyroclastic andesitic material, largely confined to the Dalles-Mount Hood syncline. These very similar units are geographically separated by overlying andesites including the present Mount Hood cone, and past workers have suspected that they may share a common source. Prior to this study, few geochemical data were available for the Rhododendron and the Dalles Formations, compared to the well studied Columbia River basalts underlying them and the overlying Pliocene andesites. This geochemical study was designed to investigate certain aspects of the Rhododendron and Dalles Formations such …

Conductance In Restricted-Dimensionality Accumulation Layers, A. B. Fowler, A. Hartstein, Richard A. Webb

Faculty Publications

Conductance has been studied in metal-oxide-silicon field-effect transistor accumulation-layer samples in which it is possible to constrict the channel to small dimensions both perpendicular to the surface and perpendicular to the channel. A temperature-dependent conductance σ=σ₀exp[-(T₀/T)ⁿ] is observed, where n=1/2 for small channel widths and n=1/3 for larger channel widths. It is believed that this behavior arises from a transition from one-dimensional to two-dimensional variable-range hopping in the sample.

The Future Of Woodenboat Shipyards, Thomas H. Wolstenholme

Marine Affairs Theses and Major Papers

It has been said that wooden boats are a thing of the past. They are now a piece of art which is admired by most and owned by few. This research examines three areas of concern to the traditional wooden boatyard owner- the social demand for his services, the economics of purchase and operation and the ever-increasing legal regulations and requirements. The availability of new materials (i.e. fiberglass) and the tremendous marketing campaign that accompanied its arrival led to a major change in the construction of recreational boats beginning in the 1950's. However,with spiralling costs of petroleum, and thus its …

A Theory Of Small Program Complexity, Kenneth I. Magel

Computer Science Faculty Research & Creative Works

Small programs are those which are written and understood by one. person. Large software systems usually consist of many small programs. The complexity of a small program is a prediction of how difficult it would be for someone to understand the program. This complexity depends of three factors: (1) the size and interelationships of the program itself; (2) the size and interelationships of the internal model of the program's purpose held by the person trying to understand the program; and (3) the complexity of the mapping between the model and the program. A theory of small program complexity based on …

Stochastic Modeling Of Individual Resource Consumption During The Programming Phase Of Software Development, Daniel G. Mcnicholl, Kenneth Magel

Computer Science Technical Reports

In the past several years there has been a considerable amount of research effort devoted to developing models of individual resource consumption during the software development process. Since many conditions affect individual resource consumption during the software development process, including several which are difficult if not impossible to quantify, it is our contention that a stochastic model is more appropriate than a deterministic model.

In order to test our hypothesis we conducted an experiment based upon several student programming assignments. Data from this experiment is used to demonstrate that the two parameter Log-Normal distribution is appropriate for describing the probabilistic …

Relativistic Sum Rules And Integral Properties Of The Dirac Equation, S. P. Goldman, Gordon W. F. Drake

Physics Publications

Relativistic generalizations are derived for the well-known nonrelativistic electric-dipole oscillator-strength sum rules. The relativistic sum rules include both positive- and negative-energy states. The derivations are valid for a Dirac electron in an arbitrary local potential. We also present a number of simple integral properties related to the relativistic virial theorem which are useful in the calculation of matrix elements. © 1982 The American Physical Society.

E1-E1 Damping Interference In The Electric Field Quenching Of Spin-Polarized He+2s12 Ions, A. Van Wijngaarden, R. Helbing, J. Patel, Gordon W. F. Drake

Physics Publications

When a beam of spin-polarized metastable He+2s12 ions is quenched by an electric field E, the emitted radiation intensity contains an asymmetry term proportional to (kE)(P'k×E) where P' is the spin-polarization vector and k is the direction of observation. The resulting asymmetry is nearly proportional to the level width of the 2p12 state in He+. The experiment provides the first observation of the asymmetry. The measured asymmetry is (0.007 69±0.000 10) in agreement with the theoretical value 0.007 618 and corresponds to a lifetime 2p=(0.988±0.013)×10-10 sec. © 1982 The American Physical Society.

Measurements Of An E 1-M 1 Interference Effect In The Electric-Field Quenching Of Spin-Polarized He+2s12 Ions, A. Van Wijngaarden, Gordon W. F. Drake

Physics Publications

When a beam of spin-polarized metastable He+2s12 ions is quenched by an electric field E, the emitted radiation intensity contains an asymmetry term which is proportional to kE ×P, where P is the spin-polarization vector and k is the direction of observation. The effect is due to interference between spontaneous magnetic-dipole (M 1) and induced electric-dipole (E 1) decay modes to the ground state. At |E|=38.14 V/cm, the measured asymmetry is (0.3230.085) × 10-3 in agreement with the theoretical value 0.3443 × 10-3. The experiment provides the first measurement of the relativistic M 1 matrix element for the 2s12-1s12 transition …

The Unintended Impacts Of Anti-Redlining Legislation, Risa Palm, James Corbridge

Geosciences Faculty Publications

Federal and state legislation intended to curb the practice of geographic loan discrimination or redlining may have the unintended and undesirable effect of preventing mortgage originators from using environmental characteristics as criteria in lending evaluations. Since the California fault rupture zones (special studies zones) do not contain systematic concentrations of poor, black, or elderly households, they should be targets for differential lending policies, such as mandatory earthquake insurance or structural reinforcements as conditions for mortgage loans. A clarification of the wording of the Housing Financial Discrimination Act is needed to alleviate some of the present potentially damaging effects of failing …

Protein Synthesis In Rabbit Reticulocytes: Characteristics Of The Protein Factor Rf That Reverses Inhibition Of Protein Synthesis In Heme-Deficient Reticulocyte Lysates, Michael Grace, Robert O. Ralston, Ambica C. Banerjee, Naba K. Gupta

Chemistry Department: Faculty Publications

During heme deficiency in reticulocyte lysates, the heme-regulated translational inhibitor of protein synthesis (HRI) is activated and shuts off protein synthesis. In partial reactions, HRI phosphorylates the M_r 38,000 subunit (α subunit) of eukaryotic initiation factor 2 (eIF-2), which forms a ternary complex, Met-tRNA_f•eIF-2•GTP. The eIF-2α(P) thus formed is not recognized by two eIF-2 ancillary factors, Co-eIF-2B (which promotes the dissociation of the ternary complex at high Mg²⁺) and Co-eIF-2C (which reverses the inhibition of ternary complex formation), and thus, is presumably inactive in peptide chain initiation. A protein factor, designated RF, which reverses inhibition …

Geochemical And Glacio-Geomorphic Implications Of Basalt Weathering In The Queen Maud Mountains, Antarctica, R. W. Talkington, Paul Andrew Mayewski, H. E. Gaudette

Earth Science Faculty Scholarship

Summary. The weathering of a suite of basalt clasts. that have been transported by mass wasting downslope in the Cumulus Hills region of the Queen Maud Mountains. Antarctica. is examined from both geochemical and glacio-geomorphic viewpoints. Chemical weathering. predominantly oxidation and hydration. increases in severity from clast core to rim for the suite. These weathering processes and concomitant formation of a weathering rind are suggested to be an accumulative process. culminating in the disaggregation of the rock due in part both to the chemical breakdown of the interstitial and intersertal basaltic glass and to physical weathering processes. Mass wasting rates …

Upper Rennick Glacier Ice Massfluctuation Study, Paul Andrew Mayewski

Earth Science Faculty Scholarship

Glacial geologic mapping conducted during the 1974-75 field season revealed that at least two glacial events have affected the upper Rennick Glacier region: an older Evans glaciation probably correlative with a major expansion of the east antarctic ice sheet, and the Rennick glaciation, which since the end of the late Wisconsin has been in a retreat phase (Mayewski, Attig, and Drewry 1979). Ice surface reconstructions suggest that (1) in the area of the current Rennick Glacier grounding line, approximately 120 kilometers inland from its current terminus, Evansice was at least 1,000 meters higher and Rennick ice as much as 600meters …
