Development Of An On-Line Computer System For Cyclic Voltammetry Studies, Tai-Lee Leo Huo

Chemistry & Biochemistry Theses & Dissertations

An Apple II Plus microcomputer was interfaced to a PAR 174A Polarographic Analyser, an HP 7O4OA X-Y recorder and a three-electrode system. This on-line computer system was applied to Cyclic Voltammetry (CV) studies. The interfacing involved both hardware and software development. Various hardware components were used to amplify and transmit the analog signal both going into the computer and coming from the computer. Software programs were written for staircase waveform generation, data acquisition, and plotting the voltammograms obtained.

A package was designed for CV experiments to be used by the students in the instrumental analysis laboratory. This package contains several …

Angle-Resolved Photoemission From Bromine Chemisorbed On Ni(100), Peter A. Dowben, Y. Sakisaka, T.N. Rhodin

Peter Dowben Publications

Molecular bromine dissociatively adsorbs to form a chemisorbed overlayer on Ni(100). The bromine induced 4p_x,y and 4p_z orbitals have been identified at Γ̅ with binding energies of 6.6 ± 0.2 eV and 5.3 ± 0.2 eV below the Fermi energy, respectively. The relative ionization cross-section variations of the two bromine levels 4p_x and 4p_z are observed to differ with changing photon energy.

Analog Computer Simulation With Automatic Scaling By Digital Computer, Mark Anthony Motter

Electrical & Computer Engineering Theses & Dissertations

A computer-aided design approach for the simplification of analog computer simulation is presented. The simulation configuration consists of an EAI 2000 analog computer with serial communications link to a PDP — 11/24 digital computer. Under control of the PDP-11, the analog simulations are realized with appropriate time and magnitude scaling which adjusts the range of the simulation coefficients and prevents overloads of the analog components. The analog computer hardware configuration accommodates both stable plants up to eighth order and closed-loop systems up to tenth order. Cascade compensation is provided for the closed-loop systems.

The plant may be described by either …

Color Display Of Vowel Spectra As A Training Aid For The Deaf, Amir Jalali Jagharghi

Electrical & Computer Engineering Theses & Dissertations

The objective of this research was to develop a transformation for mapping speech parameters to color parameter. This transformation is done in real-time, and the resulting color parameter are continuously displayed on a color monitor. This visual speech display is to be used as a speech articulation training aid for the deaf. The conversion of speech acoustic signals into speech parameter was accomplished using special -purpose electronics. The real-time conversion of speech parameter to display parameter was controlled by an 8086/8088 microprocessor operating in an S-100 bus structure. The coefficients of the Karhunen-Loeve series expansion of speech power spectra were …

The Apparent Dissociation Constants Of Carbonic Acid In Low Salinity Waters, Ching-Hui Hsu

OES Theses and Dissertations

The first and second apparent dissociation constants of carbonic acid in artificial seawater and diluted artificial seawater, K₁ ' and K₂ 1 were determined at selected combinations of temperatures and salinities between 2 to 30° C and 0 to 35 o/oo with special attentions to waters with salinities below 20 o/oo at atmospheric pressure by measuring K₁ ' and the product of K₁ ' and K₂.

The results can be expressed as functions of temperature and salinity by the following equations, pK₁ '=3360.206T^-1 +0. 033331 T-14.8303-0.09633x (Cl^1/2) pK₂ '=14911.671 …

The Mean Return Time To A State For A Markov Chain Representing In Telephone Conversations, M Luhanga

Tanzania Journal of Engineering and Technology (TJET)

The mean return time to a state for a Markov chain representing N off-hook telephone conversations can be obtained by using ergodic flow rates [1] or renewal theory [2]. In this paper it is shown that the same result may be obtained by using no more knowledge of stochastic processes than the solution of time-homogeneous Chapman-Kolmogorov equations.

The Mechanics Of Low Orbiting Satellites Implications In Communication, Lane Brostrom

Undergraduate Honors Capstone Projects

Low orbiting satellite communication networks will be competing with geosynchronous satellites for a share of the communications market. In world-wide communications that do not require immediate real time transmissions, low orbiting satellites are competitive with geosynchronous satellites because the system is reliable and low in cost.

Since satellites are a clear example of Newtonian laws, the distinct patterns they make in their orbiting process are predictable. Newton's law states that an object will remain in uniform motion unless acted upon by a force: a satellite remains in motion around the earth because there is no atmosphere to slow it down. …

Pollution In The Mediterranean: A Regional Response, Antony O. Heimer

Marine Affairs Theses and Major Papers

Pollution of the Mediterranean Sea has been an issue of significant political, economic and environmental concern for more than a decade. It has more recently become a regional issue with politically diverse coastal states and a wide variety of international agencies implementing cooperative programs of scientific research, education and training, planning, and treaty drafting. Being a regional issue, the pollution problem has facilitated discussions between nations on several levels and governments have found it politically advantageous to use the issue for a variety of purposes.This paper will provide an overview of the Mediterranean pollution problem, covering the nature of the …

The Feasibility Of A Zone Of Peace, P. R. Kendrick

Marine Affairs Theses and Major Papers

Starting in 1964 there has been a movement to declare the Indian Ocean a "Zone of Peace." In an age when many in the world feel threatened by the potential of nuclear holocaust this is not striking in and of itself. What the Zone of Peace proposal provides is more valuable than the actual resolution. Empirically, it is obvious that nuclear free zones and peace zones have little validity. Historically, the weak have been vanquished by the powerful; their proclaimed neutrality notwithstanding. Consequently, a study of the peace movement in the Indian ocean may be utilized to investigate why proclamations …

A Meta-Level Extension Of Prolog, Kenneth A. Bowen, Tobias Weinberg

Electrical Engineering and Computer Science - Technical Reports

Prolog has many attractive features as a programming tool for artificial intelligence. These include code that is easy to understand, programs that are easy to modify, and a clear relation between its logical and procedural semantics. Moreover, it has proved possible to create clear and efficient implementations. Nonetheless, we perceive several shortcomings. Chief among these is difficulty representing dynamic databases (databases which change in time) and an apparent restriction to backward chaining, backtracking, and depth-first search. Our intent in this paper is to present an extension to Prolog, called metaProlog, which preserves the virtues of Prolog while introducing powerful constructions …

DMAOVC.BAS is a computer program written in the compiler version of microsoft basic which performs factorial analysis of variance/covariance with expected mean squares. The program accommodates factorial and other hierarchical experimental designs with balanced sets of data. The program is writ ten for use on most modest sized microprocessors, in which the compiler is available. The program is parameter file driven where the parameter file consists of the response variable structure, the experimental design model expressed in a similar structure as seen in most textbooks, information concerning the factors (i.e. fixed or random, and the number of levels), and necessary …

The Petrology And Mineralogy Of Tertiary(?) Olivine Trachyte In The Harrington Peak Quadrangle, Southeastern Idaho, Amanda Shearer-Fullerton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Harrington Peak Quadrangle is located within the Caribou National Forest of southeast Idaho. Within this quadrangle are outcrops of olivine trachyte of Pliocene(?) age overlying sedimentary rocks of Mississippian to Tertiary age. The region contains thrust faults and later normal faults (generally trending north-south} formed during Basin and Range extension.

The Largest outcrop of olivine trachyte (approximately1 1/2 X 3 km) probably formed as the result of a fissure eruption. Two other outcrop areas show evidence of being sites of local extrusion.

Whole-rock chemical analyses revealed the olivine trachyte to have moderate amounts of SiO₂ and Al_{2O …}

Approaching Distributed Database Implementations Through Functional Programming Concepts, Robert M. Keller, Gary Lindstrom

All HMC Faculty Publications and Research

The application of functional programming concepts to the data representation and querying aspects of databases has been discussed by Shipman and Buneman, et al. respectively. We argue the suitability of a function-based approach to additional aspects of database systems, including updating, transaction serialization, and physical distribution and communication. It is shown how the NmergeH extension of a purely functional model permits serializable concurrent "primary site" distribution control. We also present preliminary experimental results which indicate that a reasonable degree of concurrency is attainable from the functional approach.

Measuring R And D Productivity, Richard A. Pappas, Donald S. Remer

All HMC Faculty Publications and Research

Measuring the productivity of an R&D organization is extremely tricky. Productivity is usually defined as a ratio of an output, like number of cars produced on an assembly line, to an input, like the wages paid the workers. While R&D may have a measurable input, the output is often intangible and difficult to quantify. This is further complicated because the return from an R&D department may not be realized for one or two decades,which means the time lag is much higher than in factory measurements. Furthermore, many researchers believe that this kind of measurement may be counterproductive,since the mere act …

Collecting Data About Logic Simulation, Roger D. Chamberlain, Mark A. Franklin

All Computer Science and Engineering Research

Design of high performance hardware and software based gate-switch level logic simulators requires knowledge about the logic simulation process itself. Unfortunately, little data is publically available concerning key aspects of this process. An example of this is the lack of published empirical measurements relating to the time distribution of events generated by such simulators. This paper presents a gate-switch level logic simulator lsim which is oriented towards the collection of data about the simulation process. The basic components of lsim are reviewed, and its relevant data gathering facilities are discussed. An example is presented which illustrates the use of lsim …

Spring Flow In A Portion Of Grand Canyon National Park, Arizona, David Bruce Goings

UNLV Theses, Dissertations, Professional Papers, and Capstones

Hermit, Monument, Salt, and Horn Creeks flow through four side canyons of the Colorado River within the Grand Canyon. They lie just west of Grand Canyon Village on the south side of the canyon. Each of these creeks is fed by at least one spring.

Comparisons of flow at each of these springs for a 14 month period, and precipitation on the south rim show a close correlation. The lag period between recharge at the rim and discharge at the springs is less than one month for Hermit Creek and between one and two months for the other three creeks. …

Origin Of The Peaked Structure In The Conductance Of One-Dimensional Silicon Accumulation Layers, Richard A. Webb, A. Hartstein, J. J. Wainer, A. B. Fowler

Faculty Publications

We have made extensive studies of the temperature, gate voltage, and electric field dependences of the conductance peaks in small silicon inversion layers in order to distinguish between resonant-tunneling models and a hopping model. We find that many of the peaks are consistent only with a hopping model, whereas some could be consistent with an early resonant-tunneling model. None of our structure is consistent with resonant tunneling if the recent formulation of Stone and Lee is correct.
