Data Acquisition And Parameter Identification In Electro-Oculography, Wolfgang Poelzleitner

Theses

Electro-Oculography (EOG) is used in clinical ophthalmology to measure the time response of the corneoretinal potential (CRP) to changes in light intensity. An automatized data acquisition and system modeling link has been developed that significantly reduces processing time presently required for EOG. The data acquisition is performed on a microprocessor based instrument, which supervises the EOG-test, measures the potential and, after completion of the test, transfers the results to a mainframe computer. Parameter identification routines provide graphical representation and mathematical models for the CRP. Both nonlinear curve fitting methods and Least Squares System Identification schemes are used.

A Mini Apple Network For Apple Ii Plus Computers, Michael E. Harnage

Retrospective Theses and Dissertations

Computer networks have become increasingly popular over the last ten years. A simple low cost Mini Apple Network that uses Apple II plus computers and Apple's Parallel Interface Cards, is presented here. The Mini Apple Network is driven by PIC DRIVER, a software program that is able to transmit an Applesoft array variable from one computer to another. Three application programs are presented. A comparison is made of the gain in execution time when one, two, and three computers are used to solve the same problem, namely Laplace's partial differential equation. An increase in gain was obtained when the number …

The Relative Importance Of Competencies Needed By Industrial Energy Managers From The Larger Manufacturers In Iowa, Timothy J. Eibes

Graduate Research Papers

The importance of identifying the competencies needed by energy managers is reflected in the seriousness of the energy problem and the impact it has on the industrial setting. The newness and ambiguity of EM, coupled with the increasing importance of the concept, add to the need for identifying the necessary competencies required in managing energy.

Ideally, once these competencies are identified, they should be the focus of those educational curriculums designed to produce energy managers. Currently there are only 25 post-high school institutions in the U.S. that have energy management curriculums (The College Blue Book, 1981). Less than half of …

The Design Of A Deep Ocean Hydrophone, Michael F. Hackathorn

Retrospective Theses and Dissertations

A design for a deep ocean hydrophone is proposed here. The hydrophone's sound sensing element is comprised of a capped end, piezoelectric cylinder. This sound sensing element is encased in an acoustic coupling fluid filled elastomeric boot. A small diameter tube communicates hydrostatic pressure from the coupling fluid to the interior of the sound sensing element for hydrostatic pressure compensation. The theoretical free field voltage sensitivity, the ratio of open circuit voltage to incident acoustic pressure, is predicted from mathematical model of the sound sensing element.

Fuel And Process Efficiency's Affect On The Selection Of Surface Heat-Treating Processes, Christopher Scott Thorman

Graduate Research Papers

Ever since the advent of the Industrial Revolution part components and tooling have required production heat-treating to maximize life. Various forms of heat-treatment are available to heat-treating technologists and engineers, all of which have their advantages. To maximize investment, managers must decide between new processes to gain efficiency and the updating of current process to improve efficiency. Cost considerations are important but not the only ones. Quality and safety are also important to remember.

Production capacity, both present and future, is also related to cost effectiveness of heat-treating process. The heat-up and cool-down aspect which is a vital characteristic to …

An Experimental System For Observation Of The Rat Coronary Microcirculation Using Digital Image Processing, Wolfgang Braun

Theses

A system was constructed which allows direct observation of the coronary microcirculation of the beating rat heart. An EKG triggered strobe is used on the microscope light source to "stop" the action of the beating heart so the surface microvessels can be observed di rectly under the microscope. Experimental results are recorded on videotape and played back for frame-by-frame analysis of the data using digital Image processing techniques such as digital filtering, image extraction, image enhancement and edge detection.

The application of image enhancement techniques (high order and low order enhancement methods ) as well as edge detection using a …

Proposed Product Plan For A High Growth, High Technology Organization, Alan R. Eschbach

Theses

Analyzing and consequently redefining a corporation's product line or mix is an important task facing all manufacturing organizations. While this task is usually addressed in detail as part of an organization's business plan, it can be very disconcerting when an organization realizes that the markets and products that got them to where they are now will not necessarily be the ones that will give them the growth that they would like to realize. Redefining the product line can be even more critical to young, high technology organizations who have never done it before and have found themselves facing the possibility …

Management Of The Interface Between Product Design And Production, Adam Fischer

Theses

The goal of this thesis was to identify some of the many obstacles which tend to, in some way or manner, delay the timely, satisfactory progression of new developments from becoming new profit items. These obstacles which are numerous are the results of personal observation plus research of many books and periodicals. The identification of the obstacles will hopefully result in their obviation. Notable accomplishments along these lines tend to:

1. Reduce the loss of opportunity to gain an appreciable market share.

2. Reduce investment/overhead cost by earlier recovery of cost through earlier marketing effort.

3. Reduce continuing engineering costs …

Prediction Of Enthalpies Of Mixing With A Generalized Unifac Model, Steven Otto Hetzel

Theses

The UNIFAC model of Skjold-Jorgensen et al (1980), which incorporates a general temperature dependence for the coordination number is used in the correlation and prediction of heats of mixing for binary liquid mixtures. Correlation and prediction of n-alkanes and cyclic-alkanes with alkenes, ketones, aldehydes, esters, ethers, acids, nitriles, nitroalkanes, and aikynes have been performed in a temperature range of 0 to 100°C. Typical prediction and correlation errors of 5 to 20% are obtained using this model.

A Parameter Identification System For The Human Visual Evoked Response, Robert Kalle Michaels

Theses

The Human Visual Evoked Response (VER) provides a useful tool for analyzing an individual's visual system. However, mere inspection of the signal may not always be the best way to make a diagnosis of the patient. To aid in this diagnosis a parameter identification system has been developed which fits the response to an analog model. The development of the model was based on the results of a survey of previous work in the field. Data were acquired from a data acquisition/processing system developed at the New Jersey University of Medicine and Dentistry and the Eye Institute of New Jersey. …

Criteria Measurement in EDP Auditing is a planning technique to assist the Internal Audit function in systematically selecting software applications for budgeted audit reviews. The objective is to develop a risk analysis method, which is not time and labor intensive, that will minimize risk to the corporation and maximize audit effectiveness. The methodology does not consider probabilities or occurrence rates because risks to the EDP environment are extremely difficult to forecast with traditional techniques. The method provides for both objective and subjective risk determinations.

The approach is to measure software risk criteria for a specific data processing environment. Risk concerns …

Kinetics And Reactivity Of The 2,4-Tolyene Diiscoyanate With 2-Hydroxyethyl Methacrylate Reaction, Menq-Fong Shieh

Theses

The kinetics of the addition of 2-hydroxyethyl methacrylate(HEMA) to 2,4-Tolyene diisocyanate(2,4-TDI) were studied at the temperature of 25°C, 30°C and 38°C. Reactant and product concentrations were monitored by liquid chromatography.

The rate equations for the series-parallel second order reaction have been developed and integrated by the Runge Kutta-Gill method. The results show that the para

group is about 12 times more reactive than that of the corresponding ortho group with the HEMA hydroxyl group at 25°C, and small amount of HEMA diadduct invariably produced.
