Adjustable Low Frequency Servo Compensation Using Operational Amplifiers, Charles P. Partin Oct 1980

Adjustable Low Frequency Servo Compensation Using Operational Amplifiers, Charles P. Partin

Retrospective Theses and Dissertations

This paper defines a variable transfer function that is used to compensate for low frequency structural resonances in a turret so that stabilization of a closed loop servo system can be achieved. Three circuits for implementing this compensation are presented. They are: the feedforward three amplifier biquad, the summing four amplifier biquad, and the single amplifier biquad with pole-zero cancellation. Design equations allowing the engineer to go directly from the given transfer function to the actual component values are developed for each circuit. A comparison of the final circuit designs is also presented.


Zooplankton Abundance And Diversity In A Hydrilla Infested Central Florida Lake, Don C. Schmitz Oct 1980

Zooplankton Abundance And Diversity In A Hydrilla Infested Central Florida Lake, Don C. Schmitz

Retrospective Theses and Dissertations

Zooplankton abundance, hydrilla biomass, and physicochemical parameters were sampled for one year in a small central Florida lake. Annually, rotifers comprised most of the species collected and were the most abundant zooplankton group. Hydrilla biomass was lowest during winter and spring while orthophosphate and phtoplankton concentrations were highest. Zooplankton densities were highest when hydrilla biomass was low. Small-bodied limnetic herbivores comprised most of the zooplankton during the spring. Zooplanton abundances were lowest during summer and fall and may have been either directly or indirectly related to the hydrilla growth.

Project Scheduling Under Constrained Resources, Mohammed Benameur Oct 1980

Project Scheduling Under Constrained Resources, Mohammed Benameur

Retrospective Theses and Dissertations

This report examines the widely acceptable Heuristic and Exact procedures for solving the problem of project scheduling and control under constrained resources. Heuristic approaches are more practical, however they depend on the type of the project as well as the resources involved. Exact procedures are illustrated using an Integer Linear Programming formulation of the problem, and also solving it using the Branch and Bound Technique. Impracticality of the exact methods stews from the fact that the computations expand to an unmanageable amount.

The filtration media, which consisted of a mixture of sand and alum sludge, substantially improved effluent water quality. Average reductions of over 80 % were observed in concentrations of dissolved orthophosphorus, total orthophosphorus and total phosphorus. Reductions were also experienced in iron, aluminum, copper and zinc concentrations. A prototype filtration model is …


The Separation Of Piperylene Concentrate By Extractive Distillation, Mary Jane Curnutte Jul 1980

The Separation Of Piperylene Concentrate By Extractive Distillation, Mary Jane Curnutte

Retrospective Theses and Dissertations

Piperylene concentrate, the five-carbon olefin and diolefin by-product of ethylene production, is being produced in increasing quantities as liquid feedstocks become more prevalent. At present, the concentrate is used primarily in resin production for the adhesives industry. Since this use is economically unattractive, a separation of the concentrate into pure compounds is industrially desirable. The evaluation of the effectiveness of several solvents for extractive distillation of piperylene concentrate was performed. This study resulted in the selection of acetonitrile as the most effective and most economical solvent investigated. Various distillation conditions were studied and optimization was based on these results.
