Sharpness Ratings Of A Complete Imaging System, David Blanchard Jan 1977

Sharpness Ratings Of A Complete Imaging System, David Blanchard

Theses

In a complete imaging system, consisting of a camera and a camera lens, four black and white films, an enlarger, a print made from each film and a number of observers, the resultant images were judged subjectively. The system was also evaluated by four acutance models. When the acutance ratings were compared with the sharpness ratings there was not a significant correlation between the two ratings. The author believes that there would be a better correlation between the two ratings if the acutance models were used under the same conditiobs and the same constants as they were formulated under.


Predation By Birds On Great Southern White Butterflies As A Function Of Palatability, Sex, And Habitat, F. Harvey Pough, Lincoln Brower Jan 1977

Predation By Birds On Great Southern White Butterflies As A Function Of Palatability, Sex, And Habitat, F. Harvey Pough, Lincoln Brower

Articles

A natural population of Ascia monuste studied in Everglades National Park in January 1970 was subjected to intense attack by birds. Of 697 individuals examined, 22.8% had been caught at least once by a bird. Predation intensity was greater in an open habitat (26.8%) than in a wooded one (14.4%). In laboratory experiments female A. monuste are significantly less palatable to blue jays than males and consequently should be better protected against birds. Contrary to expectation, there was no difference in the incidence of beak marks on males and females in the sample of wild butterflies. Wild females may have …


Glycosyltransferase Activity In Developing Sea-Urchin Embryos, Irene Evans, H. Bruce Bosmann Jan 1977

Glycosyltransferase Activity In Developing Sea-Urchin Embryos, Irene Evans, H. Bruce Bosmann

Articles

The developmental course of activity changes of 4 endogenous membrane glycosyltransferases: UDP-glucose : glycosyltrasferase, UDP-galactose : glycosyltransferase, GDP-mannose: glycosyltransferase, and UD-PN-acetylglucosamine : glycosyltransferase was determined in various stages of developing sea-urchin embryos from unfertilized eggs up to the 16-cell stage. The results show that there is a 2-fold increase in glycosyltransferase activity after fertilization. These results are discussed in relation to the postulated role of glycosyltransferases in mediating adhesion, recognition, and agglutination of cells and embryos.


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 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.


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 …


Increasing Visual Detectability In Reduced Exposure Mammography By Contrast Adjustment, Stuart Richer Jan 1977

Increasing Visual Detectability In Reduced Exposure Mammography By Contrast Adjustment, Stuart Richer

Theses

The radiobiologic level from an average direct-exposure, fine-grain mammograph approaches 4000 millirads. Copying reduced-exposure mammographs onto high gradient films yields a method of reducing radiation to the patient by a factor of 2. A mathematically based tone-reproduction system was developed in an attempt to produce acceptable facsimile images from a series of reduced-exposure mammographs. Acceptability was tested by radiologists using a sensitometric phantum. The radiologists were asked to quality rank a full exposure mammograph, facsimile mammographs, and a film-screen mammograph in terms of detectability of size and number of calcifications. Based on evidence, there is reason to believe that a …


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 …


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 …


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.
