Otter: A Testbed Submersible For Robotics Research, Tim Mclain, H H. Wang, R L. Marks, S D. Fleischer, D W. Miles, G A. Sapilewski, S M. Rock, M J. Lee, R C. Burton

Faculty Publications

Untethered, unmanned submersibles (UUSs) have the potential of becoming useful tools in nuclear reactor inspection and repair and waste-site cleanup and survey, in addition to subsea exploration. Classical "hand-in-glove" control methods used currently by tethered, remotely-operated vehicles (ROVs) are unsuitable for UUS systems which have, at best, limited communications. The Stanford Aerospace Robotics Laboratory (ARL) has joined with the Monterey Bay Aquarium Research Institute (MBARI) in a program to develop new methods of controlling UUS systems.

As a part of this effort, a submersible testbed has been built to test and develop new technologies that will make UUSs useful tools …

Historic Preservation And The Civil Rights Movement Of The 1950'S And 1960'S: Identifying, Preserving, And Interpreting The Architecture Of Liberation, Robert Weyeneth

Faculty Publications

This report surveys the extent to which the civil rights movement of the 1950's and 1960's has been commemorated in the United States. It concludes that there are wide-ranging and imaginative efforts not only in the South but all over the counny that seek to identify, preserve, and interpret historic sites associated with the civil rights movement These efforts, however, have been hampered by the difficulties of commemorating chapters of history that are local, recellt, and controversial. These problems of selectivity are analyzed in order to facilitate incorporation of missing aspects of civil rights history into future heritage preservation projects. …

Consensus Of The Governed: The Legitimacy Of Constitutional Change, Raymond Shih Ray Ku

Faculty Publications

This Article argues that, contrary to current practices, constitutional change is legitimate only when it commands the unanimous support of the people, or, because unanimous support is practically impossible, when it is accomplished through procedural devices (i.e., representation, ratification, and supermajority support) that safeguard minority interests in an effort to determine the public good and approximate the will of the people as a whole. Constitutional change is illegitimate when it represents only the will of a portion of the people. This Article attempts to answer the question of what makes a constitution or a constitutional amendment legitimate, and provides specific …

Phonatory And Articulatory Changes Associated With Increased Vocal Intensity In Parkinson Disease: A Case Study, Christopher Dromey, Lorraine Olson Ramig, Antonia B. Johnson

Faculty Publications

This study examined changes in voice and speech production in a patient with Parkinson disease as he increased vocal intensity following 1 month of intensive voice treatment. Phonatory function and articulatory acoustic measures were made before and after treatment as well as 6 and 12 months later. Pre- to post-treatment increases were documented in sound pressure level in sustained phonation, syllable repetition, reading, and monologue. Consistent with mechanisms of intensity change reported in normal speakers, corresponding improvements were measured in estimated subglottal pressure, maximum flow declination rate, laryngeal airway resistance, open quotient, EGGW-25, harmonic-spectral slope, and maximum vowel duration. Measures …

Case-Based Reasoning: Application Techniques For Decision Support, James V. Hansen, Rayman D. Meservy, Larry E. Wood

Faculty Publications

Decision-support systems can be improved by enabling them to use past decisions to assist in making present ones. Reasoning from relevant past cases is appealing because it corresponds to some of the processes an expert uses to solve problems quickly and accurately. All this depends on an effective method of organizing cases for retrieval. This paper investigates the use of inductive networks as a means for case organization and outlines an approach to determining the desired number of cases-or assessing the reliability of a given number. Our method is demonstrated by application to decision making on corporate tax audits.

Empirical Legal Scholarship: Reestablishing A Dialogue Between The Academy And Profession, Craig Allen Nard

Faculty Publications

Should legal academics begin to engage in a greater degree of empirical scholarship, I believe that the gap between law schools and the profession will not only cease to distend, but actually will begin to contract. If what I assert is true, or even partially true, the question remains: Why is there such a paucity of empirical legal scholarship?

Part I of this article discusses the importance and value of the empirical method and empirical scholarship by briefly exploring the philosophy of Pragmatism and its influence on the law. Thereafter, part II explores why legal academics do not engage in …

Rethinking Future Advance Mortgages: A Brief For The Restatement Approach, Dale A. Whitman, Grant S. Nelson

Faculty Publications

The advantages of such arrangements, under which the mortgagor takes none or only a portion of the loan at the outset but receives the balance in the future, are substantial. The mortgagor saves interest on the unadvanced portion until it is needed and avoids the need to invest this portion at an interest rate that at least equals the rate being paid to the lender. Moreover, both parties avoid the expense and paperwork inherent in refinancing the initial loan or in executing a series of junior mortgages to secure each advance. Finally, in the construction loan context, before committing large …

Anonymous Campaign Literature And The First Amendment, Erika Lietzan

Faculty Publications

Presently, forty-eight states and the District of Columbia have statutes that require the disclosure of some party's identity (for example, an author or a sponsor) on political literature pertaining to elections. The most common explanations given for these statutes are that they deter fraud and libel in the election arena and that they provide valuable information to the voters. Because these statutes regulate core political speech, however, they necessarily implicate the First Amendment to the United States Constitution. Although campaign disclosure laws have been both struck down and sustained by state courts reviewing appealed convictions, the decisions have been disappointingly …

Xenon 147-Nm Resonance Ƒ Value And Trapped Decay Rates, H. M. Anderson, Scott D. Bergeson, D. A. Doughty, J. E. Lawler

Faculty Publications

The absorption oscillator strength of the xenon 147-nm resonance transition is measured to be 0.264±0.016. This value is from direct absorption measurements with equivalent widths from ≈ 1 to ≈ 10 cm-1. This ƒ-value measurement is compared to others in the literature and is used in Monte Carlo simulations of trapped decay rates. The simulations include an angle-dependent partial frequency redistribution. The simulation results are compared to trapped decay rates in the literature.

Slow Motion In One-Dimensional Cahn-Morral Systems, Christopher P. Grant

Faculty Publications

In this paper we study one-dimensional Cahn-Morral systems, which are the multicomponent analogues of the Cahn-Hilliard model for phase separation and coarsening in binary mixtures. In particular, we examine solutions that start with initial data close to the preferred phases except at finitely many transition points where the data has sharp transition layers, and we show that such solutions may evolve exponentially slowly; i.e., if ε is the interaction length then there exists a constant C such that in exp(C/ε) units of time the change in such a solution is o(1). This corresponds to extremely slow coarsening of a multicomponent …

Em Interaction Of Handset Antennas And A Human In Personal Communications, Michael A. Jensen, Yahya Rahmat-Samii

Faculty Publications

In personal communications, the electromagnetic interaction between handset-mounted antennas and the nearby biological tissue is a key consideration. This paper presents a thorough investigation of this antenna-tissue interaction using the finite-difference time-domain (FDTD) electromagnetic simulation approach with detailed models of real-life antennas on a transceiver handset. The monopole, side-mounted planar inverted F, top-mounted bent inverted F, and back-mounted planar inverted F antennas are selected as representative examples of external and internal configurations. Detailed models of the human head and hand are implemented to investigate the effects of the tissue location and physical model on the antenna performance. Experimental results are …

The Impact Of Dap Inservice Training Of The Beliefs And Practices Of Kindergarten Teachers, Julia H. Haupt, Jean M. Larsen, Clyde C. Robinson, Craig H. Hart

Faculty Publications

As teacher training institutions have adopted the NAEYC standards for developmentally appropriate practices (hereinafter DAP) (Bredekamp, 1987) and have begun to routinely train pre-service teachers in these principles the need for student teaching experiences which reflect this orientation has become a priority for many teacher educators. However, locating developmentally appropriate placement settings, particularly when large numbers of student teachers are being trained simultaneously, may be difficult in some localities.

Discordance Between Lmp-Based And Clinically Estimated Gestational Age: Implications For Research, Programs, And Policy, Greg R. Alexander, Mark E. Tompkins, Donna J. Petersen, Thomas C. Hulsey, Joanne Mor

Faculty Publications

This study examines the comparability between the last menstrual period-based and clinically estimated gestational age as collected on certificates of live birth. It explores whether sociodemographic or delivery characteristics influence their agreement and contrasts health status and health care utilization indicators, such as preterm, small for gestational age, and adequacy of prenatal care percentages, produced by each gestational age measure. The 1989-91 South Carolina public use live birth files were used for this analysis. A total of 169,082 single births to resident mothers were selected for investigation.

The clinically estimated gestational age distribution exhibited a higher mean and a tendency …

Hydrogen-Atom Direct-Entry Mechanism Into Metal Membranes, G. Zheng, Branko N. Popov, Ralph E. White

Faculty Publications

The hydrogen-atom direct-entry mechanism is used to explain why the steady-state hydrogen permeation current density through a metal membrane is directly proportional to the cathodic current density, i_c, and is independent of the membrane thickness when i_c is small.

Electrowinning Of Non-Noble Metals With Simultaneous Hydrogen Evolution At Flow-Through Porous Electrodes Ii. Experimental, Mahmoud M. Saleh, John W. Weidner, Bahgat E. Ei-Anadouli, Badr G. Ateya

Faculty Publications

This paper presents an interpretation of the experimental results obtained on the electrowinning of zinc at a flow-through porous electrode in light of a mathematical model which was presented in Part I. The process is accompanied by simultaneous hydrogen evolution within the electrode, which increases the pore electrolyte resistivity and decreases the coulombic efficiency. We measured polarization curves, coulombic efficiencies, and current distributions under various conditions of zincate concentrations, flow rates, cell current, and electrode thickness. Reasonable agreement between the measured and predicted current distributions was obtained only under conditions of high electrolyte flow rates, low cell currents, and thinner …

Mathematical Modeling Of A Nickel-Cadmium Cell: Proton Diffusion In The Nickel Electrode, Pauline De Vidts, Ralph E. White

Faculty Publications

In this paper we present a mathematical model of a sealed nickel-cadmium cell that includes proton diffusion and ohmic drop through the active material in the nickel electrode. The model is used to calculate sensitivity coefficients for various parameters in the model. These calculations show that the discharge voltage of the cell is affected mostly by the kinetics of the nickel reaction. Toward the end of discharge, proton diffusion also becomes important, because the proton diffusion process affects the active material utilization significantly. During charge, the cell voltage is mainly affected by the kinetics of the nickel reaction until the …

Ac Impedance Studies On Metal Hydride Electrodes, Wenlin Zhang, M. P. Sridhar Kumar, Supramaniam Srinivasan, Harry J. Ploehn

Faculty Publications

The metal hydride (MH_x) electrode is the negative electrode in one of the most advanced secondary batteries (i.e.,nickel/metal hydride). The objective of this study is to obtain insight on the mechanism of the hydriding/dehydridingreaction in the battery by using the electrochemical impedance spectroscopy (EIS) technique. An equivalent circuit for the MH_x electrode reaction is proposed. The rate capability of charge and discharge of the MH_x electrode is determined by thekinetics of the charge-transfer reaction at the alloy surface, which is mainly represented by the EIS responses in the lowfrequency region. Transient and pseudo-steady-state analyses …

Frederic Rzewski And Spontaneous Political Music, Christian T. Asplund

Faculty Publications

I am intrigued by Frederic Rzewski's ability, in his pieces from the 1960s and 70s, to model socio-political phenomena and to teach specific lessons about these phenomena on both intuitive and intellectual levels to both performers and listeners. Performers in particular will literally experience these socio-political phenomena in the course of performing these pieces. Rzewski seems to have achieved Brecht's ideal of a gestic music without dryness or lack of credibility.

A Theory Of Verbal Completeness, Dale A. Nance

Faculty Publications

In this Article I will endorse the view that the most important modem function of the completeness rule is to trump otherwise applicable exclusionary rules, though not every rule in every instance. I will also offer the general proposition that it should almost always trump one large and important class of exclusionary rules, those based upon the "best evidence" principle, that is, the principle that parties should present to the tribunal the epistemically best evidence available to them on a given litigated issue.

Structural Ambiguities And Written Advertisements: An Inventory Of Tools For More Resourceful Advertisements In English, Dallin D. Oaks

Faculty Publications

Competent writers usually avoid ambiguity, but there are some types of writing tasks such as advertising in which a writer might actually want to create ambiguous wordplays. Among the most interesting of the wordplays are those which involve structural ambiguities. In the natural course of brainstorming, advertisers will occasionally generate structural ambiguities, but a more conscious understanding of the structure of a language could make the generation of such ambiguities easier. The English language contains some characteristics and patterns which contribute significantly toward creating structural ambiguities. And if ad writers know where to focus their attention, structurally ambiguous wordplays can …
