The Influence Of Test Colors On The Color Rendering Index Maximization In A Three Component Spectral Power Distribution, Gregory Miller

Theses

This thesis describes the technique of principle component analysis as applied to determining if a combination of three characteristic vectors would account for an underlying structure in the eight color test objects specified by the CIE for calculation of the color rendering index (CRI). Anticipated was that three vectors would account for 100 % of the variance in the eight test objects; however it was determined that three vectors account for only 96 % of the variance. Since the analysis of the reflectance functions showed no dependence within the functions a 3^3 factorial experiment was conducted. Its purpose was to …

Ash Glazes, Local Slip Glazes And Once Fire Process, Howard Skinner

Theses

My reasons for writing this thesis is to present my findings which have resulted from my explorations into the development of ash glazes, local slip glazes, once fire techniques and the production of an oriented ash glaze surface which will be consistent enough to be used on a steady line of functional dinnerware and accessories. Investigation into these areas was stimulated by a striving to join myself with the closeness of ash and natural clay glazes to the relation of the clay-forming process itself. Also the investigation has led toward the development of the once fire method which has resulted …

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 …

Subcontracting By The Petrochemical Engineer-Constructor, Michael Peter Skurla

Theses

An analysis has been made of the methods used by a Petrochemical Engineer-Constructor, who has national labor agreements, in deciding if the construction phase of a project should be done by a subcontract method of construction or be accomplished on a direct hire basis. The petrochemical complex under discussion is considered to be in the $75 million range for the total installed cost including design, engineering, procurement, and construction.

The influence of subcontracting portions of the construction phase by the Engineer-Constructor is reviewed with its impact on: the client; project schedule and cost; local and national labor relations, because of …

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 …

Reaction Kinetics For The Synthesis Of Benzyl Benzoate From Benzyl Chloride And The Triethylamine Salt Of Benzoic Acid, Michael A. Kolakowski

Theses

The reaction kinetics for the synthesis of benzyl benzoate from benzyl chloride and the triethylamine salt of benzoic acid has been studied over the temperature range of 70-105°C and a mole ratio of benzyl chloride to triethylamine of 0.5 - 10.0.

A reaction mechanism which is consistent with the experimental data has been derived. The experimental data was analyzed by means of the integral method of analysis. The temperature dependency of the reaction was determined from Arrhenius' Law and the activation energy was calculated to be 15,064 cal/g-mole. An empirical equation which explains the effects of the reactant mole ratio …

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.

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 …

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 …

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.
