Redesign Of The Rms Granularity Meter, Robert Bathgate, Filippo Ferrauto

Theses

A device for measuring RMS granularity of uniformly exposed and uniformly processed photographic material was built. This paper deals with the construction of the major components of the system. The components constructed were the lamp mount, lamp housing, current regulated ripple free power supply for the lamp, the replacement of the motor drive system for the sample stage with a synchronous motor, and the construction of the photo detection system. All these components were mounted on a triangular optical bench around an existing symetrical design microdensitometer with rotating sample stage.

The Effects Of Angularity On The Compaction And Shear Strength Of A Cohesionless Material, Richard Edward Swiderski

Theses

Several physical methods are described for the practical measurement and rating of angularity (shape) of cohesionless soil particles. Angularity is determined by utilizing the fundamental property of a sphere: a sphere has the smallest contact surface area of any shape for a given volume. Therefore, any other shape will exhibit a greater contact surface area and consequently will have a greater frictional resistance which is a function of its degree of angularity.

The effects of angularity on the physical behavior (e.g. strength) of cohesionless soils was investigated at various relative compaction densities. For this purpose a combined compaction and direct …

Non-Standard Workweek Scheduling Technique Selection, John Alexander Oak

Theses

This thesis presents a description of non-standard work scheduling techniques and a comparison method which enables decision-makers to differentiate between available work-scheduling alternatives with the purpose in mind of selecting the most appropriate and suitable arrangement. The method developed calls for the decision-maker to follow a five-step sequential process to obtain final results. The ingredients necessary to achieve such final results are obtained in a manner similar to that demanded by decision-making-under-uncertainty conditions commonly followed in actual industrial settings.

Since the primary objective of business management is the achievement of a profit through the manipulation of available resources, initial sections …

Prediction And Correlation Of The Salt-Effect In Vapor-Liquid Equilibrium, Enrique M. Bekerman

Theses

The feasibility of developing a method of correlation and prediction, for mixtures of two solvents containing a dissolved salt has been studied. The procedure consisted of arriving at the interaction parameters for the three binary systems (solvent 1-solvent 2, solvent 1-salt, solvent 2-salt) and using these to calculate the ternary results. Attempts to generate interaction parameters for the solvent-salt binaries by means of the Wilson equation were unsuccessful, whereas, use of the NRTL equation resulted in a very good fit of the binary data.

In correlating the ternary results, it became necessary to redefine the liquid phase mole fractions and …

The Recovery Of Methanol From The Mother Liquor Of A Pharmaceutical Active Ingredient, Richard Lawrence Eichholtz

Theses

The company has been sending to the sewer the filtrate from one of our chemical processes. This filtrate contains 63 vol. % methanol. The recovery of this methanol would reduce the amount of purchased methanol. The recovery would also reduce the Biological Oxygen Demand of the plant effluent. In the near future the local sewer authority will be billing the company for BOD.

The goal of the recovery process is to obtain methanol of satisfactory quality for reuse in the process from which it came. A literature search and a laboratory study verified the non-ideality of the system. Preliminary calculations …

Design And Construction Of An Edge Exposure Apparatus, Michael Benson

Theses

A means of producing photographic edges using visible radiation is often a requirement for evaluating some of the image characteristics of a photographic emulsion. The method of producing edges described uses a high quality razor blade for the knife edge held at a small angle to the film plane. The instrument is detailed and elaborates on the major features of the constructed apparatus. These features are a vacuum surface to insure film flattness; the knife edge held by a jaw-clamp assembly that pivots to allow for contrast control of the image; and exposure through a tungston-halogen lamp and an electronic …

Design, Construction, And Testing Of Sequentially Flashing Led Array To Study Angular Camera Motion In Hand Held Camera Systems, Randall Hube

Theses

This project deals with the construction of a device to determine the actual angular motion in a hand held camera system caused only by the holder. An array of LEDs (8x8) is flashed so that one LED flashes at a time in sequence. This sequence is photographed by a system suffering from motion effects and this is compared with the image of the array when no motion effects are present. The displacements of each "blip" with respect to time is used to determine the motion of the camera system.

An Investigation Of The Electrooptical Properties Of A Dipole Suspension Of Iodoquinine Sulfate, Michael Smalter, Roy Dohlen

Theses

The objective of this thesis is to investigate the electrooptical properties of a dipole suspension. A dipole suspension consists of needle-like crystals which, in the presence of an electric field, orient themselves parallel to it. If the dipoles align themselves parallel to incident light, the suspension will transmit the light. If no electric field is present, the dipoles are in a random state, and little light is transmitted. The projected area of the dipoles is smaller when they are in the aligned state. Commercially, a dipole suspension is available from Marks Polarized Corporation as the product Varad. This thesis will …

A Classroom Experience With Self-Image Enhancement As A Factor In Academic Achievement, Katherine Kellems Moore

Theses

A Classroom Experience with Self-Image Enhancement as a Factor in Academic Achievement, by Katherine Kellems Moore, investigates the connection between self-image enhancement and academic achievement in junior high students. The study was conducted with 131 randomly selected English I students in a suburban St. Louis school. Moore hypothesized that students who experienced an improvement in self-image would show corresponding gains in academic performance. Over the course of the 20-week study, students participated in personal growth activities designed to enhance self-awareness and clarify values.

The research utilized both formal academic pre/post-tests and self-reporting tools, including the Perception of Values Inventory, …

Experimenting With Varied Learning Environments In A Traditional Setting, Linda Stanford

Theses

This study, titled "Experimenting with Varied Learning Environments in a Traditional Setting," explores the integration of alternative and open classroom strategies within a conventional fourth-grade classroom in suburban St. Charles, Missouri. Conducted by Linda Stanford in partial fulfillment of her Master of Arts degree at Lindenwood College in 1976, the research investigates how varied learning environments—such as learning centers, student choice activities, and peer teaching—affect student attitudes toward learning, the teacher, and their own learning styles.

The study implemented five experimental activities: Reading Choices, a Language Block with multiple learning stations, Math Games taught to younger students, thematic learning centers …

A Study Of The Effect Of An Electric Potential On The Saponification Of Ethyl Acetate, Michael Maciupa

Theses

A reactor of rectangular cross-sectional, area was constructed of plexiglass to study the effect of an electric potential on the saponification of ethyl acetate with sodium hydroxide. Three different laminar region flow rates were used and the applied voltage was varied up to four kilovolts in one kilovolt increments for each flow rate. It was found that the apparent rate constant for the reaction was either increased or decreased depending on the voltage and flow rate used. The largest increase was a 4.2 percent change from zero voltage steady state conditions with an applied voltage of one kilovolt at a …

A Room, Ned Behnke

Theses

The purpose of this thesis is to make a series of heavy paintings on the concept of limited space using oil on canvas. The concept of "limited space" can be best illustrated in a series of rooms. I intend to accompany these with a poetic diary which will describe my techniques and will present the ideas which I included in the painting such as reflection in color. The "diary" will not be chronological, but related in the order of ideas. I will present the ideas which I have incorporated into the painting of the room especially those regarding how I …

Distinguishable Density Levels In Image Recording Of Earth Resources Satellite Data, Steven Beiser

Theses

The Earth Resources Technology Satellite (ERTS) system produces a large volume of images of the Earth, with exposed film as the final output. These Images are presented to the user in pictorial form for interpretation and analysis. Specifications for this output film include MTF requirements, development method requirements, geometric tolerance and the number of DDL's (distinguishable density levels). Given the specification of 64 levels of gray, with a minimum density range of 2.0, the following investigation is warranted. Using theoretical calculations, granularity will be determined at different density levels. Assuming that Selwyn's Law is valid for the range of apertures …

Control System For Hydraulic Hybrid Propulsion System, Vratislav Michal

Theses

A control system for a Hydraulic Hybrid Propulsion System (HHPS) is proposed and specified. Performance of the control system is evaluated by means of digital computer simulation of the total propulsion system. In order to accomplish this, analytical models of HHPS components are developed. The simulation consists of a city bus negotiating a typical driving cycle developed for this purpose on the basis of actual city bus cycle data. Performance of the control system is found to be satisfactory in all phases of driving cycle with the exception of transition from acceleration to cruise.

An Approach To Tone Reproduction For Converting Transparencies To Reflection Prints, Mark Mccormick-Goodhart, Andrew Macica

Theses

The purpose of this investigation was to study the useful criteria for converting transparencies to reflection prints, and examine the unavoidable departures from the criteria. A single useful criterion was found; that the relative brightness of the reproduction match those of the original. One significant compromise appeared to be in the shadow reproduction in low maximum density reflection prints. It was found that like reflection prints, transparencies do not typically reach relative brightnesses as low as zero. Thus, only a relatively small departure from the 1:1 criterion was likely . Flare in the camera system and viewing conditions limits the …

Performance Analysis Of A Black Liquid Solar Collector, Jackson Trentelman

Theses

The performance of a black liquid, sheet flow solar collector has been investigated both analytically and experimentally. In addition, its performance has been compared to that of a baseline collector of the tube and fin design. The black liquid solar collector was predicted to exhibit an instantaneous efficiency improvement of 10-15% over a well designed tube and fin collector. This result was confirmed experimentally. Long term efficiency calculations indicate similar performance improvements over long term use. The major contribution to improved efficiency was found to be the direct absorption process whereby a) the collector efficiency, F’, is unity and b) …

Some Reactions Of 2-Chloroethanesulfonyl Chloride, Paul Zielinski

Theses

PART 1: THE FORMATION OF 2-METHYLAMIN0-N-0CTADECYLETHAHESULF0NAMIDE FROM 2-CHLOROETHANESULFONYL CHLORIDE. 2-Chloroethanesulfonyl chloride (2) was reacted with octadecylamine (3) in the presence of triethylamine to give N-octadecylethcnesulfonamide (4), which was reacted with methylamine to give 2-methylamino-N-octadecylethanesulfonamide (1). The first reaction involves formation of the sulfonamide and dehydrohalogenation. The second reaction is a Michael addition. The formation of 1 is favored in a polg.r, protic medium. An aprotic, less polar medium produces an unwanted di-Michael adduct CH3N(CH2CH2S02NHCl8H37)2 (8), and polymer. The intramolecular hydrogen bonded structure of 1 is discussed.
