System Reliability: Exact Bayesian Intervals Compared With Fiducial Intervals, Kathryn P. Berkbigler, James K. Byers

Computer Science Faculty Research & Creative Works

This paper compares numerically two different, widely used lower limit estimates for the reliability of a series system: Bayesian limits and fiducial limits. The fiducial limits are obtained by Monte Carlo simulation because of its simplicity and ease of computer programming. Subsystem failures are s-independent and exponentially distributed; life test data are available for estimating the failure rate of each system.

A Model Of Data Structures Commonly Used In Programming Languages And Data Base Management Systems, William L. Honig

Computer Science: Faculty Publications and Other Works

This thesis claims that contemporary data structures can be understood and studied with an intelligible model which captures their essential differences and similarities and, further, that such a model is an appropriate basis for a top-down description method for data structures. To define the scope of the model, the data structures included in 21 programming languages and data base management systems have been tabulated. Each individual data structure is illustrated with an example drawn from a published paper or a working computer program. This mélange of data structures is divided into three classes (aggregates, associations , and files) and each …

Toacs : An Interactive Computer Graphic Display Model Of A Theaterwide On-Line Air Combat Simulation, Herman William Blick

Masters Theses

"On-line interactive graphics is a very effective research tool for examining the concepts, components and design parameters of theater warfare involving multiple aircraft. The aim of the present research is to design an on-line computer system which utilizes interactive graphic displays to develop a dynamic, two-sided mathematical model of theaterwide tactical fighter combat operations. The model, called TOACS, is very useful in simulating and evaluating airborne defense systems and the problems common to this type of simulation — such as the formulation of battle strategy for the commitment and guidance of interceptors against threat aircraft -- as well as those …

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu

KWRRI Research Reports

A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming the top and bottom boundaries of the aquifer as two arbitrary planes, the aquifer will be divided into six- or eight-node elements, and their nodal coordinates …

Towards A Theory Of Universal Speed-Independent Modules, Robert M. Keller

All HMC Faculty Publications and Research

Of concern here are asynchronous modules, i.e., those whose activity is regulated by initiation and completion signals with no clocks being present. First a number of operating conditions are described that are deemed essential or useful in a system of asynchronous modules, while retaining an air of independence of particular hardware implementations as much as possible. Second, some results are presented concerning sets of modules that are universal with respect to these conditions. That is, from these sets any arbitrarily complex module may be constructed as a network. It is stipulated that such constructions be speed independent, i.e., independent of …

Bayesian Confidence Limits For The Reliability Of Mixed Cascade And Parallel Independent Exponential Subsystems, James K. Byers, Ronald W. Skeith, Melvin D. Springer

Computer Science Faculty Research & Creative Works

This paper deals with the theoretical problem of deriving Bayesian confidence intervals for the reliability of a system consisting of both cascade and parallel subsystems where each subsystem is independent and has an exponential failure probability density function (pdf). This approach is applicable when test data are available for each individual subsystem and not for the entire system. The Mellin integral transform is used to analyze the system in a step-by-step procedure until the posterior pdf of the system reliability is obtained. The posterior cumulative distribution function is then obtained in the usual manner by integrating the pdf, which serves …

The Construction Of Two Prototype Multi-Storey Air-Supported Buildings, Jens G. Pohl, James Montero

Collaborative Agent Design (CAD) Research Center

To treat a multi-storey building as a large, inflatable container forces the architect to consider design and construction criteria foreign to the building industry at large. While satisfactory progress has been made in the development of theoretical solutions for problems dealing with the structural and planning implications of a hyperbaric building environment, the time has come to consider practical issues.

This paper discusses the design, construction and operation of two prototype, multi-storey, air-supported buildings. The first building was completed in November, 1972 at the School of Building, University of New South Wales, Australia, and the second building was completed in …

Are The Needs Of Industry For Data Processing Programmers Being Adequately Supported By Technical Training Programs In Oklahoma, Dale I. Sare

Electronic Theses & Dissertations

In 1970 over 40,000 computers were in use in the United States and 1,000 more on order from manufacturers. Every major newspaper had published at least one news article or editorial about computers during 1970. These articles reported how computers function, the speed at which they function, their limitations and how they have, and are continuing to become, a complex part of the business world and social affairs of man.

Digital Computer Solution Of Electromagnetic Transients In Large Power Systems, Bijan Navidbakhsh

Dissertations and Theses

This thesis is an introduction to the solution of electromagnetic transients by a combination of the Bergeran method of characteristics and the application of trapezoidal rule of integration.

Three test examples solved by digital computer illustrate the step by step solution and computer programming.

To compare this method with the Laplace transformation technique, a test problem solved by both methods and also digital computer is illustrated. In conclusion, the advantages and disadvantages of both methods are compared.

A Novel Method Of Constructing Sorting Networks, Robert M. Keller

All HMC Faculty Publications and Research

The construction of sorting networks has been a topic of much recent discussion. In view of the apparent difficulty of verifying whether a reasonably large proposed sorting network actually does sort, the most useful approach for constructing large networks seems to be to devise a recursive scheme which constructs a network which is guaranteed to sort, obviating the verification phase. In this note, another such approach is presented.

On The Decomposition Of Asynchronous Systems, Robert M. Keller

All HMC Faculty Publications and Research

This paper reports of part of a continuing investigation of parallel computation, in particular, efforts toward understanding the nature of different types of parallel control. The first section defines an asynchronous system to be a simple type of state machine. This was arrived at in an attempt to generalize from the types of control in parallel program schemata and networks of asynchronous modules without bounded delays. Asynchronous systems with output are also defined in a familiar way. The deviation from standard work comes in the definition of a parallel decomposition of asynchronous systems. Some preliminary work on compositions of this …
