This industry has proven to be very competitive, profitable and in the forefront of the present automation revolution over the …

The Decline Of Unionism With A Legal Analysis Of The Individual Rights Of Union Members, Maria-Isabel Cubides De Gast

Theses

The American labor movement has been losing power and membership for the last few years. Historical development and several facts have affected American unionism in such a manner that nowadays less than 20% of the labor force belongs to unions.

Among the most important causes of such decline discussed herein, are the following: lack of social role of unions, failure to satisfy new workers' needs, political reality under this Administration, high unemployment rate, and lack of union democracy.

Lack of union democracy is believed to be the most damaging factor for unionism's decline. Therefore it is studied in more detail, …

Air Pollutant Emissions From Non-Vented Radiant Kerosene Heater, Anil Kumar Mishra

An Analysis Of Minimum Shift Keying From The Viewpoints Of Quadrature Multiplexed And Multi-H Continuous Phase Modulation Signaling, Alfred Anthony De Seta

Theses

Minimum Shift Keying (MSK) is a bandwidth efficient modulation scheme which offers superior performance over Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK). This paper discusses these modulation techniques from a quadrature multiplexed signaling viewpoint and compares them in terms of error performance, bandwidth properties and bandlimiting and hardlimiting effects. MSK is also considered as a special case of a multi-h Continuous Phase Modulation (CPM) signal and the Viterbi algorithm is presented as an optimal detection scheme for this class of signals. A computer simulation is performed with the VA as the detection mechanism for an …

Deconvolution Techniques With Applications In Cardiovascular Systems Analysis, Lakshminarayan Rajaram

Theses

System characterization by means of Impulse and Frequency Response Functions are well known in classical linear systems analysis. Impulse Response Function is a time domain description of a linear system where as the Frequency Response Function represents the frequency domain counterpart. Linear systems are often characterized in frequency domain. In many biological research applications, it becomes necessary to examine the impulse response function in order to understand the behavior of the system under investigation. One such application is the arterial system in cardiovascular dynamics. It has been shown that although both representations are identical, some aspects of the arterial system …

Reliability Studies On Solid Tantalum Electrolytic Capacitors By Means Of Accelerated Life Tests, Venkata R. Golthi

Theses

The purpose of this thesis is to understand the failure mechanisms in Solid Tantalum Capacitors encapsulated in plastic, and to suggest the precautionary measures that prevent the occurrence of these failures.

The reliability of Solid Tantalum Capacitors encapsulated in plastic is of considerable interest because in some applications where the mechanical accelerations or shocks are considerable the "better" "hermitically" sealed type are not able to sustain themselves. Poor adherence between the dielectric film and the base metal Tantalum under the conditions of sudden mechanical shocks, causes problems.

Our study was carried out in two different directions, theoretical and experimental. The …

The Contributions Of Linn Boyd Benton And Morris Fuller Benton To The Technology Of Typesetting And Typeface Design, Patricia Cost

Theses

The relative obscurity of Linn Boyd Benton and Morris Fuller Benton, is investigated. The two men, father and son, made significant contributions to the technology of typesetting and to typeface design, yet they are not now well known in the industry. Linn Boyd Benton invented a pantographic punch-cutting machine, which he later modified to engrave matrices. This machine made the Linotype machine practical, since it took the tedium and great expense out of the making of Linotype 'mats.' Benton's machine was and still is used at the American Type Founders Company, and was copied for use at type founding companies …

Leading The Electronics Industry Into Total Automation, George P. Rossi

Theses

The introduction of an automated PCB facility in today's technological society still includes a people-oriented facility. The main thrust should be to develop Artificial Intelligence, then the incorporation of LANS, CAD, ICAM, and CIM.

The ability to lace all the functions together is by far the biggest obstacle. The hardware of the equipment is not so much the obstacle to the chemical process and knowledge as the software. Software, which is the capability to talk from the computer to the equipment, is the greatest stumbling block because there is no standardization in the language format.

The method which a computer …

Does Teaching First Grade Students About Their Personal Learning Styles Improve Their Self-Concepts?, Jacquelyn Achurch

Theses

Research on learning style based instruction has indicated its importance as a valuable tool for academic success, and improved self- concept has been viewed as a by- product of this success . Additional research has labelled self-concept as a noncognitive correlate of learning style . The relationship between knowledge of one's personal learning style and self-concept has needed to be explored. Yet, very few studies about the effect on self-concept, after being taught about ones learning style, have been conducted . Hemispheric dominance and modality preferences are formed at an early age with self- concept also being fairly well-shaped before …

Evaluation Of Flash And Fluorescent Sources With Respect To Recommended Ocular Exposure Thresholds, Mark Fairchild

Theses

A system was established for the evaluation of sources of optical radiation with respect to recommended ocular exposure limits. This system consists of a diode array radiometer calibrated for absolute radiometric measurements and software for the application of the currently accepted threshold limits for exposure to the various wavelengths of radiation. Absolute calibration of the array radiometer was accomplished to within 3 percent of values obtained by a conventional instrument. Day-to-day repeatability of the instrument indicates the possiblility of absolute calibration of the detector array responsivity for everyday use in the measurement of continuous sources to an accuracy of plus-or-minus …
