The Effect Of Recycle Control On Activated Sludge Clarification Efficiency, Joseph A. Margio

Retrospective Theses and Dissertations

Recent advances in activated sludge facilities operations utilize sludge recycle flow rate control to minimize adverse effects on the clarifier during peak solids loading situations. Although this control action is directed at the thickening function, there has been speculation that the elevated recycle rates may be responsible for an increased effluent solids concentration. To evaluate the significance of recycle rate to the steady-state effluent suspended solids concentration, identical side-by-side settling columns were operated with recycle rates spanning the range of normal practice. The studies were conducted so that each side-by-side unit received identical activated sludge feed slurries. Replicate experimental units …

Model For A Nonlinear Tank System Under Proportional-Integral-Derivative Control, Charles W. Bishop

Retrospective Theses and Dissertations

A model (NONLINRK) was developed for a closed tank system under feedback control by an ideal proportional-integral-derivative controller. Under servo action the fluid level in the tank is altered from its equilibrium set point. Under regulatory action the feed pressure to the inlet valve and/or the outlet valve percentage opening are varied from equilibrium settings. The numerical model uses Gill’s fourth-order Runge-Kutta algorithm to solve the system equation. The equation was made separable by approximating an exponential factor by the tangent at the beginning of each time step in the numerical solution. NONLINRK simulation trials exhibited many characteristics of linear …

An Algorithm For Computing Fast, Accurate, Z-Plane Root Locus Plots, David R. Jahn

Retrospective Theses and Dissertations

Root locus analysis/synthesis is an extremely powerful tool used in classical control system design. Its results can be used to check stability, speed of response, and system damping. However, the solutions to root locus problems can be extremely difficult to obtain in digital control system because the poles are in close proximity. Optimized algorithms will be presented which circumvent this problem and allow for fast, accurate z-plane root locus plots. Prompting for data entry, minimum memory in-place computations, and very little processing requirements yield an easy to use, highly efficient program.

Design Considerations For A Digital Audio Equalizer, Timothy Young

Retrospective Theses and Dissertations

The objective of this thesis is to consider a method for designing a digital audio equalizer. The primary design criteria is minimum audible frequency response error between a digital and a "reference" analog equalizer throughout the entire audio frequency range from 20 Hz to 20 Khz. The first step is to obtain a set of analog filters that suitably represent the reference equalization. From these filters, digital filter coefficients are generated using the bilinear transformation. Then, the digital filters are combined with anti-aliasing and D/A reconstruction filters and a zero-order hold to complete the design. Analysis of methods to minimize …

Digital Signal Processing Capabilities Of The Fujitsu Mb8764, Harold B. Creech

Retrospective Theses and Dissertations

The Fujitsu MB8764 digital signal processing chip is designed to operate with a machine cycle of up to 10 MHz. The chip’s ability to perform a 16-by-16 bit multiply and add operation in one machine cycle makes it a good candidate for real time digital signal processing. Unlike the Intel 2920 the Fujitsu MB8764 does not have an onboard analog-to-digital, digital-to-analog converter. Therefore, this paper will be restricted to the operation of this device with digital data input and output. The use of the MB8764 as a digital filter is analyzed. Performance limitations due to finite word length, memory size …

Publish What?, William R. Brown

Association for Communication Administration Bulletin

This article addresses the question of what kinds of scholarly work are most suitable for publication in communication studies, with particular attention to the needs of young scholars and those who mentor them. It defines publishable scholarship as “news” for the profession: work grounded in genuine intellectual curiosity, connected to significant conversations in the field, and willing to take calculated risks. The article distinguishes between general qualities of newsworthy research and more specific topics for future inquiry. Its proposed research agenda centers on symbolically negotiated patterns in human communication, including perspective-shifting, infinite regress, hypostatizing, cultural enactment, and learning. These topics …

It also cautions against premature submission, simultaneous submission to multiple journals, and inappropriate communication with editors. …

Computing Literacy In The University Of The Future, Vernon W. Gantt

Association for Communication Administration Bulletin

This article discusses the anticipated role of computing literacy in higher education during the emerging personal computer era. It distinguishes computing literacy, defined as the ability to use computers and software for practical tasks, from computer literacy, which includes programming and technical understanding of computer operations. The article argues that universities must respond to rapid developments in microcomputer technology and that faculty and administrators risk becoming less technologically capable than their students if they do not acquire basic computing skills. It surveys potential applications of computers in university teaching, research, writing, administration, advising, publishing, libraries, testing, data analysis, and professional …

A Computational Model To Estimate The Thickness Of The Waterfilm Due To Rain On The Upper Surface Of An Airfoil, Padmanabha R. Chappidi

Retrospective Theses and Dissertations

Based on a two-phase boundary layer approach, a computational model is proposed to estimate the thickness of the waterfilm due to rain on the upper surface of an airfoil. The coupling between the air boundary layer and the water film is established by the conservation of mass and momentum at the interface. By a simple coordinate transformation, the interface is conformed to the finite difference grid system. Trajectory analysis of a raindrop of 1 mm diameter shows that the impingement of drops is high near the leading edge of the airfoil and decreases downstream. The finite difference equations of air/waterfilm …

Dietary, Cognitive, And Behavioral Variables As Predictors Of Weight Loss Maintenance, Lorisa. Pearce-Lewis

Retrospective Theses and Dissertations

Obesity is a very complex problem involving dietary, psychological, social, and behavioral factors. Although behavioral treatment for obesity has been found to be effective for weight loss during treatment, results of studies to date on the prediction of long-term weight loss maintenance have been mixed and inconsistent. This study was conducted as a follow-up to a behavioral study by Zegman (1983) in an attempt to identify potential predictors of short- and long-term weight loss. Dietary, cognitive, and behavioral variables were examined by multiple regression analyses as possible predictors of short- and long-term weight loss were identified. Methodological questions were raised …
