The Orff Approach To Music Education: Objectives And Materials For Grades One Through Six, Barbara P. Spieler

Theses

This study investigates the relationship between skill objectives in the Orff-Schulwerk approach to elementary music education and Jean Piaget’s theory of cognitive development. The research begins with a detailed analysis of skill objectives as outlined in Music for Children, the foundational curriculum series for Orff-Schulwerk. These objectives are systematically ordered and examined for their developmental structure. The analysis reveals a clear sequence, beginning with fundamental abilities such as speech and rhythmic movement, progressing toward more advanced competencies including instrumental performance, melodic improvisation, and ensemble coordination.

The second stage of the study maps these Orff-Schulwerk objectives onto Piaget’s stages of …

St. Charles County Juvenile Court Diversion Programs, Charles W. Hortmeier

Theses

It has been theorized that the less formal and penetrating a youngster's contact with the Juvenile Justice System, the smaller his or her likelihood of continued delinquency. Based on this premise, known as labeling theory, the Juvenile Court of St. Charles County established several "diversion " programs to curb delinquent conduct among juvenile offenders.

This thesis was an in-depth study of these programs' effects on recidivism rates among juvenile delinquents. Court records spanning a period of 3 years were reviewed, providing the data for this research. The subjects studied were 15-year-old delinquents treated in one of three diversion programs in …

A Comparative Study Of Four Major Knowledge Representation Techniques Used In Expert Systems With An Implementation In Prolog, Joann T. Hudgick

Theses

Knowledge representation is a central issue in Artifical Intelligence (AI) research. In order to solve the diverse and complex problems encountered, one needs both a large amount of knowledge and some mechanism for the management and skillful utilization of that knowledge. The basic problem in knowledge representation is the development of an adequate formalism to represent that knowledge. In this thesis I will discuss four of the major techniques for representing knowledge in expert systems: first order logic, production rules, semantic networks, and frames. Using Prolog as the implementation language, I will demonstrate that all of the above mentioned representation …

The Design And Implementation Of A System For Processing Documents Described In Generalized Markup Languages, Frank Cost

Theses

This thesis proposes an architecture for a system capable of transforming the work of an author into printed form, and builds a partial implementation based upon that architecture. It allows an author to describe a document as a hierarchical structure and remain unconcerned about how his work will ultimately appear in printed form. The author is provided with a special markup language which can be used to tag the various logical parts of a document. The author must also be aware of how the various tagged parts fit together. The system is able to read the author's manuscript as input, …

Animator: An Object-Oriented Approach, Stephen Kurtz

Theses

Object-oriented programming is presented as a paradigm for developing interactive systems for computer animation. Object types, evolved conceptually from graphics turtles, are implemented to provide the animator with familiar metaphors for the specification of motion in three-dimensional space. The intention is to create objects that can represent actors, cameras, and decor that the user can direct and animate in a relatively intuitive manner. Vector and turtle objects support the actors, which respond to messages to orient, accelerate and draw themselves on the screen. The MacApp object libraries are used to implement the standard Macintosh user interface and a unit is …

Uguru: A Natural Language Unix Consultant, John Hanson

Theses

UGURU is a natural language conversation program, implemented in Prolog, which can manage a wide knowledge base of facts about Unix. The range and wording of questions that it understands are based on surveys taken of students, mostly Unix beginners. UGURU is also designed to accept statements in English that can be added as facts to the knowledge base. Each fact is represented as a "binding set:" a verb-oriented semantic net with the characteristics of directed acyclic graphs. The main actions taken by UGURU are divided between two primary modules, a parser and a retriever. To produce a binding set …

A Toolkit For Uncertainty Reasoning And Representation Using Fuzzy Set Theory In Prolog Expert Systems, Marcelle M. Bicker

Theses

This thesis examines the issue of uncertainty reasoning and representation in expert systems. Uncertainty and expert systems are defined. The value of uncertainty in expert systems as an approximation of human reasoning is stressed. Five alternative methods of dealing with uncertainty are explored. These include Bayesian probabilities, Mycin confirmation theory, fuzzy set theory, Dempster-Shafer's theory of evidence and a theory of endorsements. A toolkit to apply uncertainty processing in PROLOG expert systems is developed using fuzzy set theory as the basis for uncertainty reasoning and representation. The concepts of fuzzy logic and approximate reasoning are utilized in the implementation. The …

A Domain Specific Expert System Tool For Building Photofinishing Process Diagnostic Systems, King Choi

Theses

The knowledge-based method is a new and useful technique to build computer systems for applications which are heuristic rather than algorithmic in nature. This paper discusses how the approach can be applied to photofinishing process diagnostics. A prototype system for diagnosing Process E-6 for Kodak Ektachrome films is built to understand the knowledge structure and inferencing criteria for photofinishing process. The experience gained from building the prototype Process E-6 diagnostic system has been applied to the design of an expert system tool for building photofinishing process diagnostic systems without the direct involvement of a knowledge engineer.

Signature File Access Methodologies For Text Retrieval: A Literature Review With Additional Test Cases, Karen Caviglia

Theses

Signature files are extremely compressed versions of text files which can be used as access or index files to facilitate searching documents for text strings. These access files, or signatures, are generated by storing "hashed" codes for individual words. Given the possible generation of similar codes in the hashing or storing process, the primary concern in researching signature files is to determine the accuracy of retrieving information. Inaccuracy is always represented by the false signaling of the presence of a text string. Two suggested ways to alter false drop rates are: 1) to determine if either of the two methologies …

Investigation Of Steady Incompressible Flows In The Vicinity Of An Airfoil, Sivaraj Kailasapathy

Theses

O-type body-fitted coordinate systems are numerically generated about NACA0012 and NACA4412 airfoils. These coordinate systems are used to effect a coordinate transformation from the physical plane to a rectangular transformed plane. The software developed also has a coordinate contraction capability. Plots of uncontracted and contracted coordinate systems are presented.

The nonconservative, velocity-pressure formulation of the two-dimensional, steady-state Euler equations are transformed to the rectangular plane. The boundary conditions at the airfoil are determined by the source-panel method, following which, the explicit finite difference form of the transformed Euler equations are solved using a space-marching scheme. Non-lifting potential flow solutions are …

How A Printer's Marketing Strategy Affects Capital-Equipment Purchasing Decisions, Lisa S. Horwich

Theses

Marketing is a concept that is commonly believed to be the key to achieving organizational goals. This is accomplished through the determination of the needs and wants of potential customers and the deliverance of the product or service that meets this need more effectively and efficiently than any of the company's competitors.

The survey of San Francisco printers demonstrated that while the companies do employ persons in a marketing or pricing capacity, that these individuals do not play a significant role in capital equipment purchasing. Each phase in the procurement process was handled by top management almost exclusively.

The two …

Multi-H Continuous Phase Modulation : Its Properties And Analysis, Jyung-Cheng Chen

Theses

Multi-h CPM, a generalization of CPFSK and also one of the so-called Combined Modulation and Coding schemes, is useful in digital communication systems where both the bandwidth and power are constrained. The increased signal processing complexity, which can be viewed as the third communication resource, is used to trade for both power and bandwidth, and to approach the error-free communication promised by Shannon's theorem.

The transmitted multi-h CPM signal carries a coded sequence of continuous phase changes; the possible phase states form a cylindrical trellis in phase and time, in which the modulation indices are reused in a cyclical fashion. …

Effect Of Center Of Gravity Location On Optimum Performance Of Random Vibratory Vehicle Suspension, Daniel Mahar

Theses

This study provides the analysis for the optimal design of a conventional vehicle suspension system, consisting of a sprung mass (vehicle body) and two unsprung masses (wheel frame), accentuated by the implementation of a damped absorber to the unsprung masses. Further, the effect of the c.g. (center of gravity) location of the vehicle body is investigated. A two dimensional, four degrees of freedom linear model is chosen. Randomly profiled terrain is assumed to impart hyperbolically distributed stationary vertical random displacements to the front and rear wheels. For generalization, nondimensional design parameters are selected. Criteria for optimization include the tire-terrain normal …

Mythography, Christopher Losee

Theses

Although it was written over a year before this section, the thesis proposal which appends this report still serves as a good introduction to my ideas on myth in general , and in particular to my way of thinking when I began this inquiry into the photographic representation of myth. In exploring the visual and artistic dimensions of myth, I found that my thoughts and feelings on the subject changed vastly as the work progressed; however, the end result of this process of exploration has led me back to the beginnings of the work and allowed me, as T,S. Eliot …

An Enrollment Projection Simulation, Dianne Bills

Theses

This thesis applies current computer science technology to the simulation of student behavior, called Student Flow, in higher education. Data Flow Diagrams were modified for Student Flow analysis and used to help select parameters relevant to the simulation. A longitudinal database of enrollment activity was retrieved and analyzed to generate simulation statistics. The simulation was implemented using an electronic spreadsheet. The model thus developed was then used to project future student enrollments.

Combined Query Language (Cql): An Interactive Query Language With Procedural Features, Ilia Levi

Theses

Interactive query languages provide easy to use interfaces to database systems. However, they lack the power of the host languages to perform manipulations on data. This thesis presents an interactive query language Combined Query Language (CQL) that has some features of procedural languages. CQL allows users to interactively manipulate databases and perform calculations on data. CQL is a self contained interactive query language that combines the computational power of a host language (like FORTRAN) with the convenience and flexibility of the common interactive query languages. Users of CQL would not have to use a host language for most of the …

Structuralism, Charles N. Smith

Theses

Structuralism is an interdisciplinary form of modern painting that suggests the illusion of movement and growth through the conscious manipulation of flat colors and abstract geometric forms. The practice of Structuralism involves more than a grasp of the craft of painting. The artist is required to understand and practice the laws of proportion as founded by the early Egyptians and Greeks. He must have an understanding of modern color theory and he must master and practice the laws of visual perception as stated by the Gestalt psychologist, David Katz.

I have tried to recreate the chronological development of Structuralism by …

Investigation Of The Control Information Content In The Transient Regime Input/Output Data, Matthew Strack

Theses

This report represents an analysis of the determination of the information content in a selected pair of system data points from the input/output of the plant. The given system contains a random variation condition which leads to the introduction of an adaptive control loop. A procedure for adaptive control is proposed, based upon the information content in the selected pair, for implementation in a microcomputer-based system. The determination of the selected pair as well as the adaptive control laws are based upon extensive computer simulation of the system. This computer-design technique aids in the development of "switching" conditions for the …

Technology Transfer Between Developed And Developing Countries, Tenny Oghogho Ogbomo

Theses

The problems arising from technology transfer, in general, are not new. The problems of the East-West technology transfer, for example, are based on the risk that such transfers will enhance the military capability, or at least the military potential, of the trading partner. In the case of United States trade with the Soviet Union, it can be said that any accretion in the Soviet military capacity weighs against the United States in an overall world-wide balance of power. The restrictions and/or prohibition of such transfer of technology are problems themselves.

The North-South technology transfer, in other words, the technology transfer …

Replacement Of Surface Ducted Rays Near Caustics With Guassian Beams, Carlos Javier Ruiz

Theses

Conventional approach to a solution of a wave propagation problem in an inhomogeneous medium is to utilize either rays or modes to represent the wave field. Asymptotic ray theory (ART) starts to fail in the vicinity of caustics due to rays experiencing many reflections. Even uniform representations do not properly correct this deficiency of rays when caustics start to pile up in the far range. One possible alternative is to replace these rays with modal bundles and remainders [1]. A promising technique using Gaussian Beams has been used to represent the total field due to a point or a line …
