Video Detection And Tracking Of Tracer Particles In A Model Packed-Bed Reactor, Jerry Stephenson, James Wiedenhoeft, James Vallino Jan 1977

Video Detection And Tracking Of Tracer Particles In A Model Packed-Bed Reactor, Jerry Stephenson, James Wiedenhoeft, James Vallino

Articles

A video detection and tracking system was devised to track and record the position versus time of tracer particles moving through a transparent medium. The system was applied to studying the flow-related transport phenomena at all points within packed-bed reactors since the previously proposed mathematical models for describing them have not been proven adequate throughout the entire packed-bed. A modified TV camera was used to obtain a video presentation of the motion of a highly reflective particle in an otherwise transparent bed. A microcomputer was then used to process the video signal, using the vertical and horizontal sync pulses as …


The Quantitative Identification Of E-6 Chemical Processing Errors, Peter Buck, Donald Betz Jan 1977

The Quantitative Identification Of E-6 Chemical Processing Errors, Peter Buck, Donald Betz

Theses

This thesis contains descriptions of current methods of identifying chemical processing errors, followed by a description of a proposed method for quantitatively identifying chemical processing errors. The goal of this research is to determine the relationships between chemical deviations in the first developer of Kodak Color Reversal Process E-6 and the resulting changes in the sensitometric parameters of Kodak film type Ektachrome 64 Professional (Daylight). These relationships are presented in graphical form in a section of this thesis entitled "Results and Conclusions".


A Digital Signal Processing System Developed For The Optimal Use Of High Density Magnetic Storage Media, Victor Hernandez Jan 1977

A Digital Signal Processing System Developed For The Optimal Use Of High Density Magnetic Storage Media, Victor Hernandez

Theses

High density data recording has traditionally been an essential factor in the development of communication and transmission systems. However, recently more sophisticated applications, including video recording, have necessitated refinements of this technology. This study concentrates on the signal processing techniques used to inhance the packing density of stored data. A comparison of the spectral mapping characteristics of different codes illustrates that the need for equalization can be eliminated and that significant bandwidth reduction can be achieved. Secondly, consideration is given to the deleterious effects of flutter, its associated effects on high density data recording, and the constraints imposed on the …


Finite Element Analysis And Program For Stokes Fluid Flow, Jeffrey Steele Jan 1977

Finite Element Analysis And Program For Stokes Fluid Flow, Jeffrey Steele

Theses

The theory and computer program for finite element analysis of Stokes (creeping) fluid flow is presented. The element is an eight node, two dimensional isoparametric quadrillateral. The element is formulated directly from the Stokes equations of motion, a special case of the Navier-Stokes equations where inertia terms are dropped, using the method of weighted residuals with Galerkin's criterion applied. Velocities in two directions are solved for at all eight nodes while pressure is solved simultaneously at the four corner nodes only. Several test cases have been run with the program. Very good accuracy was achieved in modeling velocity profiles for …


The Design Of Fail-Safe Logic, Harvey Becker Jan 1977

The Design Of Fail-Safe Logic, Harvey Becker

Theses

This paper examines the behavior of digital logic families, specifically identifying the properties and characteristics of digital fail-safe logic. Fail-safe digital design is examined utilizing classical logic and semiconductor theory. The effects of failures internal to the structure of digital integrated circuits are analyzed and a discussion of pertinent logic design is presented. The techniques to detect all types of multiple failure modes are examined. With these results, a method of design for fail-safe logic is presented and analyzed.


Interaction Of Bromide And Organic Antifoggants In Development, Miriam Decastro, Kim Eisenberg Jan 1977

Interaction Of Bromide And Organic Antifoggants In Development, Miriam Decastro, Kim Eisenberg

Theses

Various levels of bromide and an organic antifoggant, benzotriazole, were combined in a developer and investigated to determine if an interaction existed. Both nitrogen burst agitation and viscous development were used. It was found that benzotriazole is such a strong antifoggant that interaction occurs only at low density levels, and the influence of benzotriazole increases with development time.

Quantitative Analysis Of Phenidone And Derivatives In Photographic Developing Solutions, Charles Augello Jan 1977

Quantitative Analysis Of Phenidone And Derivatives In Photographic Developing Solutions, Charles Augello

Theses

Spectrophotometric analysis and visual titration methods have been applied to the determination of Phenidone, its 4-methyl and 4, 4-dimsthyl derivatives, in photographic developers. The visual titration method is modified to allow for variation due to operator technique. Spectrophotometric methods are utilized for the identification of the Phenidone derivative in the Kodak process E-6 first developer. The derivative is believed to be Dimezome at 0.3 g/l.


A Technique For Calculating Atmospheric Scattering And Attenuation Effects Of Aerial Photographic Imagery From Totally Airborne Acquired Data, A.J. Szydlik Jan 1977

A Technique For Calculating Atmospheric Scattering And Attenuation Effects Of Aerial Photographic Imagery From Totally Airborne Acquired Data, A.J. Szydlik

Theses

Image degradation of color aerial photography due to atmospheric effects is spectrometrically evaluated as a function of air column depth for the purpose of defining corrective terms for the conditions under which the particular imagery was acquired. The theoretical development illustrates how these terms may be used to 'subtract out' the atmospheric effects of back-scatter and attenuation from the imagery. The technique suggests that true spectral information of ground objects can be calculated despite the presence of atmospheric effects during aerial photo graphic data collection. To determine the validity of the technique, the totally airborne method results are compared to …


An Analysis Of Kirlian Electrophotography, Robert Suba Jan 1977

An Analysis Of Kirlian Electrophotography, Robert Suba

Theses

The objective of this research effort was to investigate the process of Kirlian electrophotography with respect to the physical processes which occur during the exposure, and the electrical parameters of the exposing device. This project was not intended to discuss what possible parapsychological phenomina are revealed by Kirlian electrophotography, or it's possible applications. The following is a list of conclusions which were drawn from the experimentation. 1) The Kirlian image is a result of a complex process known as field emission of conducting objects under an applied high voltage AC field. Furthermore, it is the belief of the author that …


The Cqdrng8 - A Quadratic, Isoparametric, Axisymmetric Finite Element For The Nastran Computer Program, John Gray Jan 1977

The Cqdrng8 - A Quadratic, Isoparametric, Axisymmetric Finite Element For The Nastran Computer Program, John Gray

Theses

The development of an axisymmetric ring finite element is presented and FORTRAN subroutines for implementing the capability into the MSC/NASTRAN finite element program are given. The element is an eightnoded isoparametric quadrilateral of quadratic order. The following matrices and capabilities are developed: 1. stiffness matrix for homogeneous isotropic materials, 2. thermal conductance matrix for homogeneous isotropic materials, 3. calculation of equivalent nodal forces due to temperature loads, 4. calculation of stresses, and 5. plotting of undeformed and deformed structures. Several classical thermal and structural problems are solved to demonstrate these capabilities. In all cases, the element results compare well with …

Effects Of Polyox In Fountain Solution, Jacob Varughese Nov 1976

Effects Of Polyox In Fountain Solution, Jacob Varughese

Theses

"Polyox" is a polymer of ethylene oxide. It is soluble in water and commercially available. The effects of Polyox in fountain solutions were studied and evaluated. The same concentration (one-half percent of Polyox in water) at different pH and blending times, was tested for physical properties and printability. The physical property tests made were of viscosity, surface tension and contact angle. The printability tests were conducted as roll-up, ability to clean up the plate, resistance to scumming, printing sharpness and resolution properties. The experiments were conducted under controlled press conditions and the properties of each test solution were reported. Roll-up, …
