Protein Concentration Elevations In Mouse Lungs Following Sudden Transient Cephalad (+Gz) Acceleration, Charles J. Gutierrez

Retrospective Theses and Dissertations

Laboratory and feral lineages of mice were subjected to cephalad (+G_Z) accelerations, for 1.8 seconds, aboard a solid fuel rocket. Spectrophotometric analysis of bronchoalveolar lavage retrieved post launch revealed significant (p < .001) elevations of protein in the lungs of experimental mice. Sudden transient imposition of a mean +G_Z acceleration of 6.22 ± .47 (SD) G, at lift-off, may have induced hypervolemia of basilar pulmonary microvasculature with concomitant migration of fluid and protein from intravascular to juxta-alveolar perivascular compartments. Exudates may have entered bronchiolar airways subsequently gravitating toward alveoli.

Computer Modeling And Design Of State Space Feedback Control System For A Process Veneer Dryer, Allen D. Nease

Retrospective Theses and Dissertations

This thesis describes the design of a state space feedback control system for a process veneer dryer. The input variable is dryer atmospheric temperature and the output variable is veneer moisture content. As usual in the design of control systems for real-world processes, the biggest task was modeling the system to obtain the system differential equation and state space representation. The system equation derived from the model was checked against the behavior of the real-world system using the Advanced Continuous Simulation Language (ACSL) software package run on a VAX 11/750 computer. From the system equation a state space control system …

Fiber Optic Fluid Level Sensor, Navid Ghandeharioun

Retrospective Theses and Dissertations

A fiber optic fluid level sensor based on light transmission attenuation due to bending losses is designed, built and tested.

Fibers formed with reverse curvatures of decreasing radii will induce and increasing amount of lower order mode light loss to the cladding as the light propagates along the step index multimode fiber. The sensor is arranged in the fluid in a vertical position such that the light travels along the fiber from the bottom or low fluid point to the top or full point. As the fluid covers increasing lengths of the exposed fiber, it strips even more power from …

Phase Statistics For A Lightwave Traveling Through Turbulent Media, Donald J. Link

Retrospective Theses and Dissertations

A probability density function is developed for the phase of light that is the result of adding a signal to noise with K-distributed amplitude and uniform phase. The probability density function of the phase associated with the I-K distribution is also developed. In the process of deriving the probability density function of the phase much I as learned about the relationships between different probability density functions. Three different methods of deriving homodyned K statistics are shown to be equivalent. Two different methods of deriving I-K statistics are shown to be equivalent. Theoretical moments of the homodyned K distribution are compared …

Survey Of Texture And Shading Techniques For Visual Flight Simulation, Walter R. Steiner

Retrospective Theses and Dissertations

Shading and texturing are two techniques that flight simulators can take advantage of to increase scene realism. Shading imitates the effects of light reflecting from a surface. Texture refers to superimposing a pattern on a surface to give the illusion of extra detail and realism.

In this report, several techniques for shading and texturing are evaluated with respect to their applicability to visual flight simulators.

The image quality produced by shading and texturing is a function of computation cost. The Phong model is found to produce the most realistic shading, but is too computationally expensive. The Gouraud shading model improves …

Stability Of Steel Structures, Abbas K. Hosseini

Retrospective Theses and Dissertations

In the design of an elastic structure, a major consideration is the overall stability of the system under axial load or a combination of an axial load and bending moment. In first-order analysis the effects of axial forces on the stiffness formulation and their influence on deformations of the members are usually neglected. If the axial forces are sufficiently large, a better indication of the distribution of the forces and moments in the structure is obtained by using a second-order analysis. In this type of analysis the moment equilibrium equations are based on the deformed shape of the structure. The …

Experimental Software Package For Linear Programming, Deborah S. Fogal

Retrospective Theses and Dissertations

A software package for linear programming has been developed using the revised simplex and dual simplex algorithms. The design of the program incorporates an experimental change in the dual simplex algorithm. If the entered problem is not primal feasible, a modified dual simplex algorithm is used. The traditional dual simplex method requires an initial dual feasible basis and maintains feasibility throughout its application. The experimental change is to ignore this criteria of dual feasibility. The objective then becomes to obtain primal feasibility. Once this is attained, the revised simplex algorithm is applied to obtain optimality, if this has not been …

Evaluation Of A Binary Spatial Light Modulator Correlator Using Time-Domain Polarity Coincidence Correlation Theory, Thomas J. Posluszny

Retrospective Theses and Dissertations

Time-domain Polarity Coincidence Correlators (PCC) have been studied for the possible extension of these theories to the spatial-domain in the context of an optical PCC. The existing body of knowledge has been found to be inadequate for direct application to the spatial-domain. However, by remodeling the type of clipper or hardlimiter used in the development of the existing theory from a signum (bipolar) clipper to a binary (unipolar) clipper, a new expression for the output signal-to-noise ratio of an optical PCC is developed. This modification is necessary to account for the unipolar nature of light intensity. Both the existing time-domain …

Experimental Investigation Of Campbell Pacific Nuclear Corporation Mc-1 Density-Moisture Nuclear Gauge On Sand, Clay, Asphaltic Concrete And Concrete, Carl H. Francois

Retrospective Theses and Dissertations

The time-consuming traditional methods of determining soil density and moisture content have been widely replaced by more advanced techniques using radioactive isotopes such as cesium, americium, and beryllium. To ensure the validity and accuracy of the results from a nuclear gauge unit designed by Campbell Pacific Nuclear Corporation, a conventional standard test, the sand cone replacement method, was used in tandem with the nuclear instrument for the density and moisture content determination in sand and clay at different sites. The results of the two methods of measurement agree within close limits. An empirical equation was derived to correlate the data …

Infiltration Through Roadside Swales, Eduardo. Avellaneda

Retrospective Theses and Dissertations

In recent years, there have been efforts to develop a design procedure for swale systems which could be applied to permeable soils. This design should consider space limitations or any other site restriction. Five existing swale sites in the Central Florida area were instrumented to determine flow rates and permeability’s. Twenty-two experiments were performed. It is concluded that the use of a double-ring infiltrometer to determine the infiltration rate is possible for existing swale sites. Another conclusion is that published values of permeability are very variable and accurate, nor specific enough to predict actual infiltration rates. However, very conservative values …

Multiplan Models For Construction, Edson. Jackson

Retrospective Theses and Dissertations

As computer hardware becomes smaller and increasingly less expensive, more contractors can now use computers to do a number of construction computations which were formally done on hand calculators. The advent of user-oriented software packages has had a significant impact on the traditional data processing procedures of the construction industry. Among the software packages that are available for a large number of computer systems are electronic spreadsheets. Electronic spreadsheets packages, such as Multiplan, are widely used where the display of information can best be depicted in an array of rows and columns.

Internal Precision And The Common Sample Rate, James C. Kirkwood

Retrospective Theses and Dissertations

The relationship between internal precision and input/output precision and the ratio of sample frequency to signal frequency has been described in qualitative terms for the general case and in quantitative terms for many special cases. This paper attempts to generate quantitative approximated guidelines for the general case. Lowpass and bandpass digital filters are implemented using cascaded second order sections via a program that varies the amount of internal precision available for the emulation, and calculates the error produced compared to a 64 bit standard. The errors are plotted, and general equations relating input/output precision and internal precision and the ratio …

A trace metal speciation scheme proposed by Batley and Florence (1976) was applied to determine the physiochemical forms of zinc, cadmium, lead, and copper in two Central Florida highway drainage systems. The linearity and limitations of the ASV technique were also examined. The measurements showed that (a) more than 70% of the soluble Zn and Cd in all of the waters analyzed existed as liable ionic metal (b) lead was divided between labile and non-labile inorganic forms, but one particular form, PbCO₃, predominated (c) a substantial fraction of copper is associated with organic colloids if humic substances are …

Suitability Of The Tms320 Digital Signal Processor In Digital Signal Processing Applications Requiring Multiple-Precision, Randall L. Walker

Retrospective Theses and Dissertations

The TMS320 single-chip digital signal processor, produced by Texas Instruments, shows promise for a long life-cycle not only because it fills a technical need in the digital signal processing field; but because it also represents an excellent early design. Furthermore, Texas Instruments has provided thorough software and development support. However, this chip was not designed to support digital signal processing applications which require multiple-precision operations. In this paper, algorithms were developed and expressed in macros that provide the capability of modeling systems requiring multiple-precision operations. Finally, a performance envelope showing the system complexity versus sampling bandwidth limitations is provided to …

Optimization Analysis For Alignment Criteria And Installation Of Gravity Flow Underground Pipe, Eugene N. Balter

Retrospective Theses and Dissertations

In 1982 the Business Roundtable prepared several reports which investigated various aspects of construction which posed significant research opportunities. Their findings placed piping construction in the group of activities categorized as having "highest potential" for improvements based on inefficiency, or construction difficulty and proportionate costs. It was estimated that over $1 billion could be saved annually if the difficulty in the piping industry was improved to only average of other areas. Further investigation into the piping area showed that the alignment process took 20% of the cycle time for installation and ranked either first or second as compared to other …

Application Software Of The Future-Filter Design With Gem, Alan D. George

Retrospective Theses and Dissertations

As the use of computer in engineering design as well as other areas increase, it becomes more imperative that the application software used be as simple, convenient, and powerful as possible. The engineer is not interested in the internal workings of the computer or its operating system. It is the design itself that takes precedence. The filter design package developed for this project, known as FILTER, is such an application. With FILTER, coupled with the Digital Research Graphics Environment Manager, the engineer is led through the analog and digital filter design phase on a personal computer with carefully designed interactive …
