A Technique To Calculate Complex Electromagnetic Fields By Using The Finite Element Method, Davood Asgharian

Dissertations and Theses

A computer program based on Maxwell's equations is developed to calculate two-dimensional complex potentials by the Finite Element Method. This study offers a solution to a complex continuum problem by allowing a subdivision into a series of simple interrelated problems. The region of interest is divided into triangular elements. For each node in the grid, the Finite Element Method is used to set up an equation for the potential as a function of those of the surrounding nodes. All these equations are solved by the Gaussian Elimination Method. For increased accuracy this method requires a high degree of division of …

A Consciousness Simulation Model, R. Edward Mitchell Jr.

Theses

The thesis titled "A Consciousness Simulation Model" by R. Edward Mitchell (1977) explores the theoretical design of a digital model aimed at simulating human consciousness. The model is structured around a collection of independent processing modules that mimic various human cognitive and emotional processes. These modules include components for thought selection, ego/achievement, memory, and emotion processing, which interact with one another in a fashion that simulates aspects of human thought and behavior.

Mitchell's primary goal is to develop a system that could behave more like a human, particularly in communication and decision-making processes, to improve human-machine interaction. The thesis highlights …

Diagnosis Of Faults In Linear Tree Networks, Sharad C. Seth, K. L. Kodandapani

School of Computing: Faculty Publications

The problem of fault detection and location in tree networks of two input EXCLUSIVE-OR (EOR) gates is considered. The fault model assumes that an EOR gate can change to any other function of its two inputs except the equivalence function. An efficient procedure for single fault location is presented. In the worst case the number of tests necessary to locate single faults is bounded by a linear function of the number of input variables. Constructive upper bounds are obtained for the number of tests to detect multiple faults. Optimality of these bounds is argued and extension of results to other …

Superconcentrators, Nicholas Pippenger

All HMC Faculty Publications and Research

An $n$-superconcentrator is an acyclic directed graph with $n$ inputs and $n$ outputs for which, for every $r \leqq n$, every set of $r$ inputs, and every set of $r$ outputs, there exists an $r$-flow (a set of $r$ vertex-disjoint directed paths) from the given inputs to the given outputs. We show that there exist $n$-superconcentrators with $39n + O(\log n)$ (in fact, at most $40n$) edges, depth $O(\log n)$, and maximum degree (in-degree plus out-degree) 16.

A Computer Based Information System For The Study Of Multi-Component Populations In South Carolina, Louise Ramsey Andres

MUSC Theses and Dissertations

The information system accepts data on multi-component populations in South Carolina, and produces distribution maps, histograms, tables and other summary displays. The initial application illustrated is to the population of insects in the family Tabanid in South Carolina. The system is a series of FORTRAN programs written for an IBM System 360 Model 40 under DOS.

Reliability Growth Apportionment, James K. Byers

Computer Science Faculty Research & Creative Works

A method is presented for apportioning reliability growth to the subsystems that make up a system in order to achieve the required reliability at least cost. Reliability growth apportionment is handled as an s-expected cost minimization problem subject to the constraint of meeting a system reliability requirement. The problem is formulated in terms of Duane's reliability growth model and is solved using geometric programming. The method can be useful in the early stages of system design to determine subsystem reliability growth that will allow a system reliability requirement to be met, and in the latter stages of system design when …

A Computerized Marine Data And Information System-Endex/Oasis, Steven J. Tibbitt

Marine Affairs Theses and Major Papers

The volume of international and national environmental data and information in the marine, earth and atmospheric sciences has created the need to systematically organize, handle, manipulate, store and retrieve this material utilizing sophisticated computer hardware and provide the scientist, student, planner and decision-maker with the awareness and accessibility of available data and information. Consonant with the objectives outlined for NOAA and the need generated by the explosion of information and data in this area, the National Oceanic and Atmospheric Administration(NOAA), Environmental Data Service (EDS) and the National Oceanographic Data Center (NODC), have an ongoing development effort in the Envirorrmental Data …

An Efficient Dft Algorithm Using The Walsh Transform, Albert P. Gerheim

Electrical & Computer Engineering Theses & Dissertations

The matrix transformation relating the sequency and frequency domains is derived. It is shown that these­ frequency-to-frequency conversion can be performed via a computationally efficient sparse matrix algorithm. The sequency-to-frequency algorithm can be used with a fast Hadamard transform to implement a discrete Fourier trans­ form. The efficiencies of this combined algorithm and a radix-two fast Fourier transform are compared.

The algorithm is applied to the sequency domain de­ sign of a Wiener digital filter. Improved computational efficiencies are achieved relative to the procedure de­veloped by Kahveci and Hall (9).

The Definition Of Programming Languages, J. A. Robinson

Electrical Engineering and Computer Science - Technical Reports

There is no need to argue in favor of concise, clear, complete, consistent, descriptions of programming languages, nor to recite the cost in time, energy, money, and effectiveness which is incurred when a description falls short of these standards. Reliable, high-quality computer programming is impossible without a clear and precise understanding of the language in which the programs are written—this being true quite independently of the merits of a language as a language. In this study we tried to discover the current state of the methodology of definition of programming languages. We sought to separate the question (as far as …

Facility Costs Of Centralized Grain Storage Systems Utilizing Computer Design, Otto J. Loewer Jr., Thomas C. Bridges, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

The item considered most often when estimating the cost of a grain storage facility is capacity. Of equal or greater importance is daily harvest rate. Other important considerations include drying method, materials handling equipment, energy cost, facility arrangement, labor requirements, grain quality and management ability. Only through a comparison of facilities which offer similar capacity, capability and convenience can the purchaser obtain his best system.

Qsim2: A Low-Budget Heuristic Approach To Modeling And Forecasting, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

This paper contains a description of a simple mathematical framework and modeling process which can be used to study a large class of socio-techno-natural systems. Models may be designed using intuitive notions or data to help specify the variables, parameters and interrelationships, which, with the aid of a computer program, can be used to forecast system behavior under various assumptions. Two example models are described.
