Information Theoretic Analysis Of Multi-Stage Communication/Imaging Systems, William O'Such

Theses

A method for the system analysis of a multistage photographic or communication system is developed. By following the input signal through the system and estimating the output signal and the output signal without noise, the information capacity after each stage can be estimated. The relationship between the variance and the integral of the power spectrum is used in accounting for the effects of each of the component characteristics: modulation transfer function, density-log exposure relationship and granularity. This method is implemented in a computer program which allows one to vary the characteristics of the components and determine the resultant changes in …

There have been both empirical and non-empirical studies done that show evidence that connotations and feelings have been associated with typefaces. The intent of this study was to determine the feelings associated with a particular group of typefaces by relating each face to a list of adjective pairs and comparing the results with the content of books which incorporated the face on their jackets. This was to determine whether the content of a book and …

An Evaluation Of The Effect Of Registration On Gcr And Conventional Chromatic Separation Methods In Multicolor Halftone Printing, Chihwe Jeffrey Wang

Theses

Misregistration is an unavoidable problem in multicolor halftone printing. It causes the loss of detail, sharpness and color hue shift of a reproduction. However, there is a color separation technique called Gray Component Replacement (GCR) which may reduce or eliminate this misregistration effect. An investigation had been conducted using a series of color halftone proofs which were produced by conventional chromatic and GCR color separation techniques. The subjective image quality scaling method was applied to this study as a criterion to determine whether there is an image quality relationship between these two techniques on misregistered reproductions.

The electrostatic plate consisted of a fused toner image on an aluminum base. The intent of this research was to determine the final resolution, not the forces and factors which effected it. The hypothesis stated that the resulting resolution of the electrostatic plate …

A Model For Non-Image Area Of Offset Lithographic Process, Vinay Chhajlani

Theses

Lithography is the most common printing process. However, very little is known about the theory of lithography. Pressroom practices have evolved more out of experience than on the basis of any theory. The objective of this paper is to develop a mathematical model for the non-image area of the offset lithographic plate. A model of this kind would provide a rationalization for the observed behavior in lithographic process. The study concentrates on the various materials and the phenomena involved. Properties of aluminum oxide surface and gum arabic that make them suitable for the process have been presented. Rheological properties of …

Effects Of Exposure On The Printing Characteristics Of The Association Product Process, Claude David Davis

Theses

The investigation examined the printing characteristics of the association product plate, a continuous tone lithographic process which utilizes a synthetic, light-sensitive coating variably ink-receptive according to the degree of exposure it receives. The methodology was designed to determine (1) the printing range of the plate, (2) the effective sensitivity of the coating to varying amounts of exposure within this range, and (3) the degree to which adherence to ideal tone reproduction could be achieved through systematic variation of exposure. The plate is not commercially available, therefore it was necessary to consult patent literature and prior research to obtain details of …

The Switch Capacitor Biquad Filter And It's Application On Active Filter Design, Sung-Chiang Chang

Theses

The purpose of this subject is to use the programmable switch capacitor filter to design a traditional analog filter which usually cause a tedious job on finding a group of values for resistors and capacitors. We start from the basic concept of switch capacitor, then we learn to use auxiliary equipment to design a filter. To design the desired filter, first, we have to find the s-domain transfer function, then transfer it to the z-domain. After we found the coefficients of z-domain transfer function, we have to implement this on the auxiliary equipment. Then we will get the desired filter.

Reliability Of Existing Bridge Inspection And Evaluation Procedures, Leroy R. Klouser

Theses

In general, bridge inspection is subjective since visual observation and the basic inspection tools cannot reveal hidden structural deterioration, such as corrosive and delaminated rebars embedded in the concrete. Based on the NJDOT SI&A report, a scale (9 to 0) is used in rating five bridge components. This approach seems reasonable, since the time span, manpower and cost are limited throughout the counties of New Jersey. On the other hand, based on the scaling system, the SI&A reports can vary depending upon the exposed surface appearance and the experience of the bridge inspector.

Water, de-icing agents, freezing and thawing cycles …

Morphological Analysis Of Microvessels Using High Voltage Electron Microscopy (Hvem), Ibm Personal Computer And 3-D Reconstruction Software, Wieslaw Slawomir Krajewski

Theses

The mesenteric arterioles (outer diameter < 100 µ) from a normotensive and a hypertensive dog were perfused in situ, excised, post-fixed and embedded in Spurr medium block. Thick serial cross sections (0.5 µ) of the vessels were obtained from hand formed mesas and placed on Formvar coated slot grids.

The cross sections were subjected to High Voltage Electron Microscopy (HVEM) and five or more electronmicrographs were taken to cover the individual cross sections. The prints of electronmicrographs were linearly enlarged (3X) and made into photomontages of sections. The membrane contours in the montages were traced on transparent overlays, producing polygons which in turn were traced on GTCO digitizing pad. All polygons were labeled, color coded and stored in IBM PC's filing system. The vessels were reconstructed from up to 100 whole cross sections and subjected to cell compartmentalvolume analysis. The reconstructed images can be …

8085 In-Circuit Emulator For Ibm Personal Computer, Joong Bin Lee

Theses

As microprocessor-based systems become gradually larger, the developers need good tools for debugging the hardware and software. The emulators for the IBM Personal Computer using an RS-232 serial port are available in the market. But it takes quite a long time to download the user file to the memory of the emulator or the target system. This emulator is an add-on card dedicated for IBM Personal Computers. The emulator communicates with the IBM Personal Computer through the I/O channels on the mother board instead of the serial port, so its speed is much faster than that of the serial port. …

Optimizing Tone Production On A 300 Spot Per Inch Laser Printer, James R. Hamilton

Theses

Digital halftones as output on plain paper are the focus of this study. A new terminology is suggested to allow proper description of digital halftones. The most important of these terms is the use of "addressability" to replace the often misused term "resolution." Also important is the use of the term "spot" rather than "dot" to describe addressability. A means of properly describing digital halftones is suggested to avoid confusion with analog (ie., conventional photographic) halftones. Halftone patterns were created to test the efficiency of different designs at 300 spot per inch addressability on a laser printer. The page description …

N-Values And Paper Opacity, Robert Eric Aronson

Theses

The n-value is a factor which allows the Murray-Davies equation to be correctly solved for physical dot area or tint density. This equation becomes known as the Yule-Nielsen equation when the n-value is used.

Many variables affect the value of n; paper characteristics, screen ruling, even the equation variables themselves. The level of solid ink density may have a very significant effect on the n-value. This fact, although suspected, has not been investigated until now.

A study into this variance was undertaken in Appendix II with a method for adjusting the value of n to a standard solid ink density …

Where Have All The Nurses Gone? The Continuing Saga Of The Nursing Shortage, Deborah R. Mcfarland

Theses

This paper examines the issues which have encompassed the nursing profession for many years, thus making it a difficult career in which to attract and retain members. The nursing shortage, many say, has returned, but did it really go away? The shortage experienced in the 1970's was coupled with high admission rates and high employee turnover causing a shortage of nurses, particularly experienced ones. Then, hospitals faced the emergence of the federal government making major changes in reimbursement to hospitals. This caused a major shift in the cash flow system of hospitals. Also, costs were no longer reimbursed on a …

A Christian Counseling Handbook For The Lay Counselors, Debra K. Olson-Demmie

Theses

Counseling psychology advocates a position of neutrality where religious issues are concerned. This position appears benign at first glance, but upon closer examination we find that psychology has been strongly influenced by modern humanistic thought. In his book Psychology as Religion: The Cult of Self-Worship, Paul Vitz (1977) states, "Psychology has become as religion, in particular, a form of secular humanism based on the worship of self" (p. 9). Vitz alleges that humanistic psychology is being practiced as an anti-Christian religion.

Christian mental health and pastoral care providers need to be alert to the infiltration of humanistic thought into psychological …
