Stability Of Large Flexible Satellite, Manoj P. Mehta

Theses

The stability of a gravity gradient satellite with a rigid main body and elastic antennas is studied using Liapunov's Direct method. The complete conditions for equilibrium and stability for a particular class of two dimensional models are determined. Previous work restrained the analysis to elastic stability, in the small, and only for equilibrium positions corresponding to zero initial elastic deformation. Although the work presented here is for two dimensional motion, the intent is to bring forth an approach to the determination of the complete equilibrium and stability criteria in the large as well as the small. The effect of different …

Some Effects Of Temporal Coherence Of The Fourier Transform Holographic System, Ronald Antos

Theses

The objective of this investigation was to evaluate experimentally the effects of slight changes in the temporal coherence of a quasi-monochromatic source on the real images of Fourier transform holograms. The method of investigation included: (1) A review of some of the theoretical aspects of Fourier transform holography, (2) some approximations for experimental system limitations due to the coherence length and size of the quasi -monochromatic source, (3) sensitometric experimentation to obtain an adequate photographic reversal process, (4) temporal coherence measurements using a Michel son interferometer, (5) formation and reconstruction of Fourier transform holograms, and (6) analysis of experimental data. …

Computer Simulation Of A Linde "Double Column", John A. Bazan

Theses

The purpose of this thesis is to develop a Fortran Computer Program to simulate the operation of a Linde "Double Column" for the separation of air into oxygen and nitrogen. The model outputs the number of contact stages required, the reflux ratio, the heat loads (condenser and reboiler, and the five profiles of temperature, pressure, vapor flow rate, liquid flow rate, and light component composition. From this data, the proposed design can be evaluated, and the effect of varying operating conditions explored.

Computerized Computation Of Counter-Current Extraction Problems For Ternary Liquid Systems, Albert Warren Patterson

Theses

A Fortran computer program has been developed that will calculate the number of theoretical equilibrium stages required for a countercurrent liquid-liquid extraction design problem. It also furnishes a complete stagewise material balance. Further utility can be found by using it for optimization studies. The program can be utilized for three-component systems that form one pair of partially miscible liquids, the most frequently occuring situation. The program was written for the General Electric Mark I Time-Sharing System.

The program has a practical advantage in that isothermal liquid equilibria data are used directly for calculation purposes. No use is made of theoretically …

A Method Of Schlieren Alignment Stabilization Using Automatic Feedback Control, W. Lawton King

Theses

An investigation of the application of feedback control to schlieren system alignment stabilization is presented. A feedback control system was designed with the necessary sensors and actuator to maintain the knife edge alignment of a schlieren system. The feedback control system's performance when subjected to controlled disturbances was evaluated. The results indicated that the approach is feasible.

Statistical Separation Of Objects In Shadows From Objects In Daylight In An Aerial Scene, David Valvo

Theses

Objects photographed in an aerial scene are ordered into frequency histograms in terms of log exposure on the film. A statistical analysis shows that each distribution actually contains two separate distributions; one of objects in daylight, the other of objects in shadows. The difference is due to a variation in apparent luminance of the objects. For example, as an asphalt road passes in and out of a shadow, its absolute reflectance doesn't change but its apparent luminance does. It is also shown that the ratio of the derived shadow distribution to the daylight distribution is exactly the same as the …

A Study Of The Influence Of Iodide Released During Development On The Course Of Development, Barry Britton

Theses

The Influence of iodide released during development on the course of development was Investigated by transferring known amounts of iodide to Kodak Panatomic X Film and Eastman Fine Grain Release Positive Film (Cine Positive) after exposure and before development. Iodide was transferred to the films being tested by soaking dry Bimat web material in potassium iodide solutions and contacting this to the film for fifteen minutes. The transfer of iodide in the Bimat to the film being tested was found to be essentially complete. The iodide reacted with the grains to convert silver bromide to silver iodide. The silver iodide …

An Investigation Of The Mechanism Of Emulsion Stabilization By 4-Hydroxy-6-Methyl-1,3,3a,7-Tetraazaindene, Eddie Rising

Theses

There is considerable speculation in literature as to the mechanism of photographic emulsion stabilization by 4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene, (Aza). Aza is important as a stabilizer because, unlike the heterocyclic mercaptans, it causes no desensitization when the emulsion is processed in the commonly used MQ developing agents. The mercaptans are strongly adsorbed, whereas Aza is weakly adsorbed on silver halide. Therefore, there has been speculation that the stabilization mechanism of Aza is distinctly different from that of the mercaptans. For this work, Aza was tested as an antifogging agent and development restrainer along with KBr, as a reference, in two developers which function …

The Effect Of Chromatic Aberration In Process Lenses On The Copying Of Reflection Halftone Dots, Burdette A. Saunders

Theses

A method for evaluation of copydot quality is determined. This method is applied to the problem of determining the relative copydot quality of two films of different spectral sensitivities, while using two process lenses with measureable amounts of chromatic aberration.

Image Spread Characteristics Of Vesicular Films, Ira Long, Alan Turner

Theses

An altered Bausch and Lomb metallograph, in conjunction with a 150 watt high-pressure Xenon-arc lamp, was used to image 50µm uniformly illuminated round spots on several vesicular emulsions and a silver emulsion to determine image spread characteristics with increasing exposure times. Vesicular films tested include Kalvar Types 16, 143, 163, and 164, a sample of Xidex Blue and a high resolution aerial film. It was found in all cases that image spread was more profound in vesicular films than in the silver film tested. It was also found that ten minute and twenty minute periods of time between exposure and …

Effectiveness Of Training Programs For Graduate Engineers, V.C. Rajashekar

Theses

This thesis represents an investigation of effectiveness as a result of engineering training. The basic elements of effectiveness and its learning process are explained and said that the effectiveness could be learnt and improved.

The term training, is basically the process of education and training. But training cannot be performed as an individual, but is performed as a group. Therefore training a group with having so many individuals needs careful consideration in designing a training program.

In order to get the broadest possible picture of current thinking and current activity in the area of company training programs for graduate engineers, …

A Study Of The Optimization Of Ethylene Production In A Tubular Reactor, Richard W. J. Robertson

Theses

The pyrolysis of ethane is a complex reaction involving six individual reactions in a reactant mixture of thirteen components. It is further complicated by the deposition of carbon along the reactor walls. The carbon buildup eventually necessitates reactor shutdown, During the intermediate stages the reactor experiences a gradual increase in inlet pressure which affects the reaction conditions, Optimum temperature profiles exist because the yield goes up with increasing temperature, but, consequently, the reactor must be shut down and cleaned out with increasing frequency. The combined effect causes the yearly production of ethylene to go through an optimum.

To find this …

The Creep And Stress Relaxation Behavior Of Silver Bearing Copper Wire, Alfred Fox

Theses

Creep and stress-relaxation experiments were performed on silverless and silver bearing copper in the temperature range 73F to 250F. The creep experiments were conducted at constant load and temperature, the stress-relaxation tests at constant total strain and temperature for a total time period of 1000 hours. The effect of silver addition of up to 0.2 percent w/o (60oz per ton) on the creep and stress-relaxation behavior of spectrographically pure copper (99.999+ Cu) as well as on that of tough pitch and oxygen free coppers of lesser purity was studied. Spectrographically pure copper was found to be much more susceptible to …

The Effect Of Ultrasonic Vibration On Mass Transfer In A Packed Column, Joseph Walter Stanecki

Theses

The object of this research was to investigate the possibility of using externally supplied ultrasonic vibration to surface of a packed distillation column operating at total reflux to improve the separation. The apparatus used for this experimentation consisted of a 2 inch ID Pyrex column having three pairs of ultrasonic transducers epoxied equidistance along the external surface of the column. Each pair of transducers was driven separately by a 50 watt amplifier! power supply and a sine/square wave generator.

There were three types of binary mixtures covered during experimentation: minimum boiling azeotropes, maximum boiling azeotropes and full range mixtures. In …
