Prediction Of Enthalpies Of Mixing With A Generalized Unifac Model, Steven Otto Hetzel

Theses

The UNIFAC model of Skjold-Jorgensen et al (1980), which incorporates a general temperature dependence for the coordination number is used in the correlation and prediction of heats of mixing for binary liquid mixtures. Correlation and prediction of n-alkanes and cyclic-alkanes with alkenes, ketones, aldehydes, esters, ethers, acids, nitriles, nitroalkanes, and aikynes have been performed in a temperature range of 0 to 100°C. Typical prediction and correlation errors of 5 to 20% are obtained using this model.

An Analysis For The Blade Coating Of Ctbn Modified Epoxy Adhesive, Jeng-Li Liang

Theses

A resin metering criterion has been developed for processing the prepregs of CTBN-EPOXY resin in which the resin content can be controlled within close tolerances. This criterion was obtained by numerically simulating the flow of CTBN-EPDXY resin in the blade-type metering device at room temperature. The Newtonion case of CTBN-EPOXY resin was selected for the study to avoid dealing with more complicated flow equations. A methodology of using the penalty function/finite element formulation was developed to solve the steady state Navior-Stokes equation.

The rheological data show that the CTBN-EPOXY resin is a non-Newtonion fluid at low shear rate. On the …

An Application Of Personal Microcomputer To Solve Mid-Sized Goal Programming Problems, Chanhon Joe Lu

Theses

This thesis develops a microcomputer software to solve mid-sized goal programming problems utilizing the revised simplex method.

Goal programming is an extension of linear programming, but is more powerful and flexible than linear programming because of its capability in handling problems with multiple conflicting objectives, instead of dealing with "one dimensional" objective - profit maximization or cost minimization. Accordingly, goal programming is very useful to the complex organizational environments.

With the help of rapid and accurate computation of digital computers, solving a complex program is not a difficult task at all. However, some medium-sized companies cannot afford a mainframe -computer, …

A Parameter Identification System For The Human Visual Evoked Response, Robert Kalle Michaels

Theses

The Human Visual Evoked Response (VER) provides a useful tool for analyzing an individual's visual system. However, mere inspection of the signal may not always be the best way to make a diagnosis of the patient. To aid in this diagnosis a parameter identification system has been developed which fits the response to an analog model. The development of the model was based on the results of a survey of previous work in the field. Data were acquired from a data acquisition/processing system developed at the New Jersey University of Medicine and Dentistry and the Eye Institute of New Jersey. …

Automated Instrumentation System For Studies Of Metabolic Rates In Rats, Suhas P. Pathak

Theses

The task of the instrumentation system is to measure the respiratory exchange in rats in a controlled experiment. Air is drawn at a predeter-mined rate in and out of rat chambers. The proportion of oxygen and carbon dioxide in the ensuing air indicates the respiratory rate of the rat. The entire operation is controlled by a microcomputer whose most important functions are: to direct the flow of air through the rat chambers by switching valves; and to collect data about the percentages of gases in question.

Thus with the help of a computer it is possible to monitor and control …

Criteria Measurement In Edp Auditing, Eugene Alexander Ottaviano

Theses

Criteria Measurement in EDP Auditing is a planning technique to assist the Internal Audit function in systematically selecting software applications for budgeted audit reviews. The objective is to develop a risk analysis method, which is not time and labor intensive, that will minimize risk to the corporation and maximize audit effectiveness. The methodology does not consider probabilities or occurrence rates because risks to the EDP environment are extremely difficult to forecast with traditional techniques. The method provides for both objective and subjective risk determinations.

The approach is to measure software risk criteria for a specific data processing environment. Risk concerns …

The Hydroxide-, Chymotrypsin-, And Blood-Catalyzed Hydrolysis Of A Series Of Sodium 4-Acyloxy-3-Nitrobenzene Sulfonates, Louis E. Rinaldi

Theses

The kinetics of the hydrolysis of a series of water-soluble aromatic esters (sodium 4-acyloxy-3-nitrobenzene sulfonates) were analyzed in order to determine the effect of a variety of substitutions (on the α-carbon of the acid group) upon the rate of reaction.

The following was observed. That (a), the hydroxide catalyzed and water dependent hydrolyses of these esters are slower for larger substituents and faster for smaller ones. That (b), the chymotrypsin catalytic hydrolysis of these esters shows an acylation reaction step which occurs at a rate greater than deacylation for larger substituents, and at approximately equal rates for smaller ones. Furthermore, …

Kinetics And Reactivity Of The 2,4-Tolyene Diiscoyanate With 2-Hydroxyethyl Methacrylate Reaction, Menq-Fong Shieh

Theses

The kinetics of the addition of 2-hydroxyethyl methacrylate(HEMA) to 2,4-Tolyene diisocyanate(2,4-TDI) were studied at the temperature of 25°C, 30°C and 38°C. Reactant and product concentrations were monitored by liquid chromatography.

The rate equations for the series-parallel second order reaction have been developed and integrated by the Runge Kutta-Gill method. The results show that the para

group is about 12 times more reactive than that of the corresponding ortho group with the HEMA hydroxyl group at 25°C, and small amount of HEMA diadduct invariably produced.

A Limited Comparison Of Ultraviolet Curing And Convection Drying On Paper Permanence, Nancy Bittner

Theses

Archivists, conservators and librarians are concerned with paper permanence. Tests have shown that paper permanence is affected by light (especially ultra violet), temperature and humidity changes, acidity, in sects and rodents, and by general use. Environmental damages are often insidious. The objective of this study is to find whether ultraviolet curing and evaporative drying as experienced in the printing industry would affect paper permanence. Glen G. Gray's procedure for finding the reaction rate (the rate at which chemical reactions are completed) of paper is followed. This method relies on the fact that a chemical reaction occurs at speeds which depend …

An Application Of Multi-Dimensional Scaling To The Re-Examination Of Preferred Tone Reproduction, David J. Porter

Theses

Black and white prints were produced of several scenes that varied in both negative contrast and negative exposure. Subjects rated the various prints by categories based on their own personal understanding of what an excellent print was. The boundaries of the categories were found and used to determine the preferred tone reproduction characteristics. Individual differences were also scaled with the use of a proximity measure determined from the categorical data. The preferred contrast (1.46 +0.24) was significantly higher than the contrast that has been found to be preferred in earlier studies. The application of this study to more general situations …

Theses

An investigation of the possibility of spin-coating a silver halide emusion similar to that used on Kodak HRP plates onto a positive resist coating reticle blank was made. By changing the cating weight and temperature of the emulsion it was found that the emulsion could be coated onto the reticle without harm to the positive resist material. A five micron width line was imaged successfully and measured in the final chrome sub-layer of the reticle.

A Decision Theory Approach To Tone Reproduction, Kevin E. Spaulding

Theses

The concepts of statistical decision theory were applied to the photographic tone reproduction system to develop an objective measurement of tone reproduction accuracy called the "expected loss" of the system. Reproductions were made of four scenes using systems with a wide range of tone reproduction characteristics. The expected loss for each system/scene combination was calculated, and the perceived tone reproduction accuracy was determined using the psychophysical scaling method of magnitude estimation. A statistically significant correlation was found between the subjectively determined accuracy, and system expected loss, but the degree of correlation was not high enough for the merit function to …

Determining Spectral Sensitivity Of Kodak Micro Positive Resist 820, Matthew L. Huck

Theses

The spectral sensitivity of KODAK Micro Positive Resist 820 has been determined for the spectral range of 300nm to 500nm. A xenon-source monochrometer was used in a hard contact exposing system. Se/isitivity is defined as the inverse of the exposure (mj/cm ) needed to produce an image in a photoresist coated plate having walls of 70 normal slope. Low intensity reciprocity law failure has been conclusively shown to exist in this resist with exposure intensities of 100 mw/cm and below. Guide lines have been drawn up, based on the procedures and results of the experimentation, to assist photoresist users in …

The Effect Of Microscope Scale Reticle Design On Variance Of Measurement, David D. Rockafellow

Theses

Little work has been documented regarding the design of optical instrument scale reticles. Reticle is the word used to describe both scales and crosshairs used in the eyepiece of an optical instrument. An ergonomic (the relation of man to his working environment) experiment was performed in which thirteen different scale reticles were designed, manufactured and tested. The design parameters tested were scale spacing, line height, and line thickness. The testing consisted of thirty observers measuring a circular test object through a microscope with each scale reticles. The results, taking into consideration both variance in measurement and observer comments, showed the …

The study examines the challenges human resource managers face in linking salary increases with performance assessments, emphasizing the limitations of traditional ranking and rating systems. The paired comparison method, which systematically compares employees against each other in pairs, is proposed as a more reliable and objective alternative.

The thesis details a study conducted with laboratory technicians, where supervisors used both conventional ranking methods and a computerized paired comparison system. Statistical analysis demonstrated a high correlation …

Design Of A High Ratio Gear Reduction Unit, Jean Xydias

Theses

This is a right angle gear drive design where helical and spiral bevel gears are being used. Because of the high speed ratio (1800/18 , input/output), three reductions were applied. Two helical gear sets were used in the first and second reductions (one each), and a spiral bevel set was used at the final reduction. The gears were mounted on four shafts, with the first and last shafts (output and input shafts) carrying one gear each straddle mounted, and the second and third shafts carrying two gears each, overhung mounted. The design was based on a criterion that was set …

The Effect Of Developer Composition On Adjacency Effects In Black And White Photography: Metol Vsl Phenidone, Paul L. Zengerle

Theses

Increased chemical adjacency effects in black and white photography can be obtained using certain Metol and Phenidone developers. Four different effects are described: 1) development inhibition by iodide ion 2) development inhibition by bromide ion 3) exhaustion of Metol 4) development inhibition by oxidized Phenidone Edge effects produced by Metol exhaustion and by Phenidone development are enhanced by moderate increases in pH. They are reduced by: the addition of hydroquinone, high levels of sodium sulfite, and high fog levels. Developers designed to increase adjacency effects also increase granularity. The trade-off betv/een acutance and granularity is approximately linear for the film-developer …

Moment Method Solution Of The Time-Dependent Transport Equation To Describe The Scattering Of Gaussian Plane Wave Pulses By A Forest, Nack Yang Cho

Theses

The time dependent transport equation is used to study the transmission of periodic pulses through a forest. The forest is assumed to occupy a half-space region, to be statistically homogeneous and to scatter energy isotropically A periodic sequence of Gaussian plane wave pulses is assumed to enter the forest normally from free space. The transport equation is solved by the moment method using triangular expansion functions. Numerical results indicate the dependence of the incoherent intensity on penetration depth, observation angle, albedo and pulse repetition rate.

Steady State Heat Transfer From Two Concentric Rings Of Spheres, Kevin J. Fitzpatrick

Theses

The method of reflections was used to solve the steady state heat transfer problem for two concentric rings of spheres, all at equal surface temperature. The method results in a mathematical model for the three dimensional temperature profiles around the array of spheres. This model is used to develop an expression for heat transfer rate from the array. This work has resulted in a solution for dilute systems since no ring to ring interaction term was found.
