Optical Noise Reduction Using Partial Coherence In Spatial Filtering For Image Detail Enhancement, Steven Lynn Musser

Theses

Coherent optical spatial filtering can be used to increase the contrast of fine detail in photographs. The images produced, however, contain optical noise blemishes that make the procedure seldom usable in practical photography. A promising method of reducing the optical noise by means of partial coherence in a projection printer has been investigated involving the use of a plurality of point sources. It has been demonstrated, using pictorial enlargements, that subjective sharpness levels may be obtained which are similar to those obtained by using specular illumination while greatly reducing the amount of coherent noise on the image. Enlargements of a …

Concentration And Conductivity Of Fountain Solutions: A Study Of The Relationship Between Concentration Of Materials/Electrochemical Conductivity Of Fountain Solutions And Offset Lithographic Plate Performance, Silva Ada Opusunju

Theses

The transfer of the image to the substrate in lithographic printing relies very much on the characteristics of the fountain solution. The quality or desensitization potential of the solution has always been determined by measurements of pH ; and by the more "recently" proposed method of electrochemical conductivity. The purpose of this study was to determine which of these techniques most suitably measured the efficiency of the solution. Since the fountain solutions were always changing during the press run, the response of pH and conductivity to changes in concentration were used as criteria for measuring their suitability. The effect on …

A Study Of The Conventional Method Of Producing Spreads And Chokes And The New Technology By Using Orbital Motion (Micro-Modifier), Sze-Men Lui

Theses

A photographic process that produces thicker or thinner images for color trapping in order to have easier registration in color printing is called spreads or chokes. A study was made of the conventional (contacting) method of producing spreads and chokes and the new technology by using orbital motion (Micro-modifier) with respect to the results on the films by measuring the printing sharpness, resolution, dot gain, base density, contrast, accuracy and uniformity of spreads and chokes. A cost study for both methods was also made. A series of experiments were designed and done in order to compare the two methods. The …

Visual Modulation Transfer Function As A Predictor Of Acuity, Thomas A. Sebring

Theses

The use of Fourier and modulation transfer techniques implies the ability to characterize an optical system and predict the output resulting from various inputs. In this study, the optical system is defined as a projection system, rear projection screen, and the human eye. A determination of modulation thresholds of visibility for a series of sinusoidal (in transmittance) test objects results after some manipulation in the modulation transfer function of the complete system. This result is then used to predict the subject's ability to resolve conventional acuity challenges. These conventional test objects are then manufactured for projection in the system. Correlation …

Direct Simple Shear Tests On Overconsolidated Anderten Clay, Maral Bedian

Theses

Determining the shear strength behaviour of a very stiff calcareous clay in the Direct-Simple Shear tests is the purpose of this thesis. The clay tested is the MLK Arderten Clay from West Germany.

For the Direct-Simple Shear tests, a trimming device was prepared to get the required size of the samples. Porous stones with nails were used to prevent the slippage of the samples.

The results of the Consolidated K_o Undrained Direct-Simple Shear tests showed that the shear strength of the clay depended largely on the condition of the samples tested. Relatively homogeneous and intact samples had shear strength …

United States V. Western Europe : A Comparative Study Of Safeguarding Practice Against Hazards At The Point Of Operation In Metal Forming Systems, Jeffrey Joseph Schwalje

Theses

The problem of assuring safety for the worker at the point of operation of a metal stamping system is complex by virtue of the multiplicity of combinations possible between all conceivable dies and a press of suitable capacity.

The means of providing safeguarding prescriptions is further compounded by maintaining a viable means to enforce the safety regulations as demanded by law.

A comparative study of the approach to this problem was made between the practices in the United States with that of Great Britain, France and West Germany.

This was accomplished through the study of the available standards, codes and …

The Heterogeneous Catalytic Decomposition Of Isopropyl Alcohol Over 0.5% Platinum On 4-8 Mesh Charcoal Catalyst Support, Thomas Michael Kudenchak

The Microdensitometry Of Image Boundaries Fabricated By The Color-Difference Blue-Screen Traveling Matte Process, Michael F. Lehman

Theses

The Color-Difference Blue-Screen Traveling Matte Process is a technique used in motion picture special effects production to composite two or more scenes into one. A complaint often made against the process is that boundaries between the composited images are often 'harder,’ i.e., there is a sharper transition between the image and their surround. Because this is visible, it is objectionable. An attempt at duplicating the process, so the boundaries could be analyzed using microdensitometry was made. Failure at key steps in the process rendered results inconclusive, but raised several interesting questions of the process. Also, a simple technique was fabricated …

Gravity Controlled Pag Double-Jet Precipitations, Adam Pudnos

Theses

An apparatus has been constructed which incorporates the use of flowmeters, micrometer valves, and assorted tubing to perform gravity controlled pAg double-jet precipitations. This unique system controls the pAg concentration by adjusting the flow rate of the halide solution. The pAg concentration is continually monitored by the millivolt output produced from a specific ion electrode for Bromide and a Calomel reference electrode. A Scanning Electron Microscope study was performed to determine whether this apparatus is capable of obtaining the same results as others, in terms of crystal size and shape, when varying pAg concentrations and precipitation time in a factorial …

Art Therapy As A Means Of Ego Enhancement For Severely And Profoundly Mentally Retardedk, Kimberly Riemer

Theses

Kimberly Riemer’s thesis, Art Therapy as a Means of Ego Enhancement for the Severely and Profoundly Mentally Retarded (1981), explores the impact of art therapy on individuals with severe and profound mental retardation. The study was conducted as part of a six-month practicum, during which Riemer worked with both children and adults in a specialized educational and vocational setting.

Drawing from psychological theories, particularly those of Erik Erikson, Riemer argues that ego development is crucial for mentally retarded individuals. She hypothesizes that if art therapy can aid emotionally disturbed individuals, it should also benefit those with cognitive impairments. Through structured …
