Automatically Generating Syntax-Directed Editors For Graphical Languages, Farahangiz Arefi

Retrospective Theses and Dissertations

This research is concerned with the automatic generation of syntax-directed editors for graphical programming languages. A specification technique that is used to uniformly define graphical languages along with their syntax-directed editors is developed. The novel aspect of this specification technique, called a general graph transformation system, is that the graphical languages are described by specifying a family of editing operations. In this manner, a language is defined as a dynamic object which, by applying different editing operations, changes from one form to another, each form representing a sentence of the language. In order to demonstrate this process, the language of …

Generating Multiple User Interfaces For Multiple Application Domains, Mahesh Hassomal Dodani

Retrospective Theses and Dissertations

This Ph.D. dissertation presents a classification scheme for User Interface Development Environments (UIDEs) based on the multiplicity of user interfaces and application domains that can be supported. The SISD, SIMD and MISD [S= Single, I= user Interface(s), M= Multiple, D= application Domain(s)] generator classes encompass most of the UIDEs described in the literature. A major goal of this research is to allow any user to develop a personalized interface for any interactive application, that is, the development of an MIMD UIDE.

Fundamental to the development of such a UIDE is the complete separation of the user interface component from the …

On K - Y - Insensitive Donimation, Teresa Haynes Rice

Retrospective Theses and Dissertations

A connected graph G is defined to be k-1-insensitive if the domination number 1(G) is unchanged when an arbitrary set of k edges is removed. The problem has been solved fork= 1. This Ph.D. dissertation focuses on finding extremal k-1-insensitive graphs on p nodes, fork~ 2. A graph is extremal if it has the minimum number of edges. Two subproblems are considered. The first, which has been solved completely, specifies that the same set of nodes dominates each graph obtained from G by removing k edges. The second requires only that the graph G be connected. This is a much …

A Relational Object-Oriented Management System And An Encapsulated Object-Oriented Programming System, Michael L. Nelson

Retrospective Theses and Dissertations

The purpose of the Relational Object-Oriented Management System (ROOMS) is to show that the relational database scheme is a viable approach for storing objectoriented data. ROOMS is designed so that it can be implemented in any object-oriented language with appropriate I/O commands, or added to any objectoriented database management system that allows userdefined collections of data. Various problems were encountered in developing ROOMS. While these problems have been solved, the best solution is to use the Encapsulated Object-Oriented Programming System (EOOPS) . EOOPS is based upon an inheritance scheme which preserves encapsulation. This encapsulated approach avoids the problems associated with …

Boundary Layer On A Continuous Flat Plate In Parallel Flow With Similar And Non-Similar Boundary Conditions, Vaughn H.M. Faber

Retrospective Theses and Dissertations

This thesis is a computational analysis of the incompressible laminar boundary layer on a continuous moving surface. The skin friction and heat transfer variations on a moving plate with similar and non-similar (constant) mass transfer at the wall are obtained for 210 cases for the similar boundary solution and 60 cases for the non-similar solution.

Both cases were solved numerically using the fourth order Runge-Kutta algorithm. For the non-similarity case, the local non-similarity method as described by Sparrow, Quack and Boerner was used. The analysis shows that the shear stress for both the similar and non-similar cases is higher when …

A Cellular Algorithm For Data Reduction Of Polygon Based Images, Robert James Caesar

Retrospective Theses and Dissertations

ABSTRACT The amount of information contained in an image is often much more than is necessary. Computer generated images will always be constrained by the computer's resources or the time allowed for generation. To reduce the quantity of data in a picture while preserving its apparent quality can require complex filtering of the image data. This paper presents an algorithm for reducing data in polygon based images, using different filtering techniques that take advantage of a priori knowledge as to the images' content. One technique uses a novel implementation of vertex elimination. By passing the image through a sequence of …

Some Optimally Adaptive Parallel Graph Algorithms On Erew Pram Model, Sajal K. Das

Retrospective Theses and Dissertations

The study of graph algorithms is an important area of research in computer science, since graphs offer useful tools to model many real-world situations. The commercial availability of parallel computers have led to the development of efficient parallel graph algorithms.

Using an exclusive-read and exclusive-write (EREW) parallel random access machine (PRAM) as the computation model with a fixed number of processors, we design and analyze parallel algorithms for seven undirected graph problems, such as, connected components, spanning forest, fundamental cycle set, bridges, bipartiteness, assignment problems, and approximate vertex coloring. For all but the last two problems, the input data structure …

Comparison Of Subsurface Cavity Investigations Using Earth Resistivity, Seismograph And Ground Penetrating Radar, Dennis M. Filler

Retrospective Theses and Dissertations

Sinkhole formation in the Central Florida area has become a serious problem. The subsurface exploration method for cavity detection is indeed needed prior to sinkhole development. this research study compares the effectiveness of earth resistivity, seismograph and ground penetrating radar (GPR) methods in the detection of subsurface cavities. A resistivity instrument measures a material's resistance to electric currents. The seismograph measure the propagation velocity of a medium refracting compressional waves. The GPR transmits and receives electromagnetic pulses reflecting off subsurface interfaces.

Tests were conducted at two sites: a model test site at the University of central Florida, Orlando, and a …

The hydroechlorination reactions were conducted in the gas phase, either in the prsence …

The Application Of Transfer Matrices In The Dynamic Analysis Of Planar Elastic Mechanisms, Richard Kent Lindenberg

Retrospective Theses and Dissertations

Transfer matrices are used in the dynamic analysis of planar elastic mechanisms. Mechanism motion is discretized by dividing the motion into a finite number of intervals over which the mechanism is considered to be an instantaneous structure with constant geometry. Transfer matrix methods are then used to calculate the natural frequencies and corresponding mode shapes of the instantaneous structure. A transfer matrix relating the continuous, non-zero components of the state vector across a pin joint is developed. An elastic four bar mechanism and a crank slider mechanism with a rigid crank and elastic connecting rod are analyzed using lumped mass …

A System For Measuring The Phase Difference Between Two Points Of A Propagating Laser Beam, Jefferson E. Odhner

Retrospective Theses and Dissertations

An optical system has been designed, analyzed, implemented, and calibrated which measures the phase difference between two points of a propagating laser beam. The system is a quadrature interferometer whose detector outputs are processed by a computer. This quadrature interferometer measures both the phase and amplitude variations between two points of a laser beam after the beam passes through turbulence . These measurements are in turn processed by a computer to isolate the phase variations from the amplitude variations. Further statistical analysis which can be performed on these phase variations should provide an understanding of the phase fluctuations of propagating …

Effects Of Grade Inflation On Speech Communication Majors, Robert C. Dick

Association for Communication Administration Bulletin

This article examines grade inflation in communication and theatre programs, situating the issue within broader trends in higher education. While national studies have shown rising undergraduate grades despite declining SAT scores, departmental data from Indiana University reveal both periods of grade inflation and more recent declines. The discussion highlights multiple causes, including liberal withdrawal policies, student pressure for career-oriented courses, faculty differences in grading philosophy, and fears of poor student evaluations. Special attention is given to challenges in performance-based courses where instructors may be tempted to inflate grades to protect student self-esteem. Potential consequences include disadvantaging strong students, undermining credibility …

Numerical Solutions Of Poisson's Equation In A Superlatice Device, Norman Todd Rollins

Retrospective Theses and Dissertations

The relationship between the built-in potential and the energy bands in a heterojunction device is defined using the Anderson model. Based on this model, Poisson's equation for a nonhomogeneous semiconductor device in thermal equilibrium is derived and solved analytically for the special case of a doubly intrinsic abrupt heterojunction. Several numerical methods of solving Poisson's equation for general cases are explored to find the most efficient method. The validity of the chosen numerical method is tested against both the analytical solution for a Ge/GaAs doubly intrinsic diode and recently published results from similar numerical simulation studies. A p-i-n superlattice device …

Closing The Gap: Improving Secondary Theatre Education, Donald L. Loeffler

Association for Communication Administration Bulletin

This article examines efforts in North Carolina to improve secondary theatre education and strengthen teacher preparation. It reviews historical patterns in which students often pursued theatre education degrees as an alternative to foreign language study, sometimes without strong commitment to teaching. Recent reforms in teacher education introduced higher standards for admission, testing, and grade point averages, alongside counseling to guide students into appropriate career paths. State legislation further required that by 1993 all students in grades K–12 have access to sequential coursework in music, art, dance, and drama. Challenges identified included inadequate preparation in technical theatre, uncertainty among new teachers …
