A Geo-Marine Informational System For Coastal Zone Management, Stella Maris A. Vallejo

Marine Affairs Theses and Major Papers

The purpose of this paper is to present a system analysis for the evaluation and interpretation of information on coastal zone management. We understand by system analysis the consideration of a complex made by related parts, and not merely a totally of parts, where the significance of one thing depends on its relationship with the others. Based on this criteria of interconnections between phenomena, we assume, we are going to give the coastal zone a treatment of a system and in this way impose a correlative statement to the information related to this area. This system approach for the information …

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 …

Computational Models Of Learning., Kenneth Jesse Marse

Masters Theses

"An investigation is made into the use of techniques which would normally be described as learning if encountered in a human being. A literature review of several subject areas including game-playing computer programs, automatic control systems, pattern recognition methods, and biological modeling is performed, with the purpose of extracting and examining those processes which exhibit learning. A general model of the type of learning most widely utilized in these areas is constructed and used to compare and contrast specific models which describe the learning techniques employed. Some specific models which do not exhibit learning as described by the general model …

Using Ibm's Information Management System To Implement A Relational Data Base, Melvin Arthur Rushton

Masters Theses

"A relational model of data has been the topic of several papers which deal with the question of the underlying design philosophy of data base systems. E. F. Codd, C. J. Date, and others have discussed the application of relation theory to formatted data, the objectives of such an approach, normalization of relations, and languages for manipulating the model (data sublanguages). Few papers have delt with storage constructs or access techniques for a relational data base. Indeed, it was not necessary that they do so, for the user of such a system is only concerned with the information available in …

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 …

Cephalometrics For The Oral Surgeon In The Diagnosis Of Facial Deformities, Frederick J. Mantz

Loma Linda University Electronic Theses, Dissertations & Projects

Surgical orthodontics presents a challenge to the oral surgeon. By the nature of the oral surgeon's training and discipline he should be the one best qualified to treat the surgical aspect of the surgical orthodontic case. The establishment of a proper diagnosis and means of communication between the oral surgeon and orthodontist are essential in achieving a good final result for the surgically treated case. Fortunately, a scientific method of diagnosis is available that can provide both specialties with a common language. Computerized cephalometric analysis can provide the diagnosis and link of communication for the discussion of goals and treatment. …

Mando : A Computer Program For Symbolic Manipulation Of Differential Operators Generating Continuous Transformations, David Kenneth Davison

University of the Pacific Theses and Dissertations

The program MANDO efficiently performs computations involving pairs of operators, a single operator, and operators applied to functions, saving time and cost over pencil-·and-paper methods.

A versatile but compact data structure, defined under SPIT-BOL's facility for creation of datatypes, contains the operators (and functions) and provides a means for systematically referencing their relevant parts.

On input, functions and operators are written in a restricted but natural string format, for which the program can readily convert them to the internal data structure.

Central to the method of operation of the derivative routine is its ability to differentiate a function written as …

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 …

Digital Computer Modeling Of Limestone Groundwater Systems, John Thrailkill, David P. Beiter

KWRRI Research Reports
