Computer Vision Of A Moving Square Using A Two-Level Data Hierarchy, David Zokaites

Theses

An investigation of the relative speed and effectiveness of two computer vision algorithms has been conducted. One algorithm incorporates a two-level data hierarchy. The other incorporates a one-level hierarchy and serves as a relatively conventional basis for comparison. The computer vision algorithms, programmed in Fortran, detect and recognize a moving square. Both computer vision algorithms could readily be implemented in existing hardware. The two-level algorithm was found to be up to 90% faster than the one-level algorithm. An analysis was made of elapsed CPU time variance as a function of time of day and user load. This was done to …

Distributed File Systems For Unix, Edward Ford

Theses

With the advent of distributed systems, mechanisms that support efficient resource sharing are necessary to exploit a distributed architecture. One of the key resources UNIX provides is a hierarchical file system. Early efforts supported distributed UNIX systems by copying files and sending mail between individual machines. The desire to provide transparent mechanisms on which distributed systems access resources has propelled the development of distributed file systems. This thesis presents a brief history of the development of distributed systems based on UNIX, and surveys recent implementations of distributed file systems based on UNIX. The IBIS distributed file system is an example …

Electrochemical Reduction Of Quaternary Ammonium Salts, Rudolph K. Kapichak

Theses

The electrochemical reduction of two highly hindered quaternary ammonium salts was attempted. The reductions were performed in hexamethylphosphoramide at a controlled potential using platinum electrodes. It was anticipated that these reductions would provide a route to the formation of anti-Bredt bridgehead olefins. This work is an extension of the work of Dubois, Monvernay and Lacaze who electrochemically reduced quaternary ammonium salts such as trimethyl-t-butylammonium iodide (XX).

Trimethy1-2,4,4-trimethy1-2-pentylammonium iodide (XXIII) was reduced to form 2,4,4-trimethyl-l-pentene (XXVI) and 2,2,4-trimethylpentane (XXV). The yields of the two runs of this reduction were 10% and 20% and in the first run of the reduction 75% …

A Presentation Of The Self-Organizing Paradigm; Speculation On Its Impact On Health, Gail Dahl Schomaker

Theses

This thesis explores the emergence of a new paradigm in understanding health, grounded in the scientific principles of self-organization and systems theory. Gail Dahl Schomaker presents a comprehensive examination of the shift from the traditional Newtonian mechanical worldview to the dynamic, process-oriented perspective rooted in the theory of dissipative structures as formulated by Ilya Prigogine. Central to this new worldview is the conceptualization of living organisms, including humans, as open systems that maintain and increase order through continual interaction with their environment.

The paper is structured to introduce key theoretical models from systems theory, cybernetics, and holistic health, progressively building …
