Theoretical And Experimental Evaluation Of Cardiac State Utilizing Indicator Dilution Methods For Nonuniform Ventricular Mixing, Stanley Myron Welland

Dissertations

This research is directed toward the development and application of a new approach to the evaluation of cardiac work to diagnose cardiac state. A procedure has been developed for calculating the work performed on the fluid by the left ventricle during the heartbeat. The procedure involves the continuous direct measurement of ventricular fluid mixture temperature during and following the controlled injection, through a catheter, of a known volume of cold saline into the left ventricle. The measured mixture temperatures are used to calculate continuous ventricular volumes during the systolic and diastolic functions of the heartbeat. Plotting measured ventricular pressure versus …

On The Classification Of The Solution Space Of Linear Anisotropic Elasticity, Richard Clement Carman

Dissertations

A method is developed within the framework of Synge's function-space interpretation of problems in linear elasticity which allows the consideration of solutions to problems for anisotropic media in terms of the solutions of a corresponding isotropic problem and corresponding simpler anisotropic problems. The isotropic solution and simpler anisotropic solutions establish points in each of the statically and kinematically admissible spaces for the anisotropic problem. The established points are used to define sets of vectors in the statically and kinematically admissible spaces. The linear independence of these vectors can then be determined by a pair of criteria developed in this work. …

A Study Of The Dynamics Of Gas Adsorption In An Air Fluidized Bed, William Charles Zalewski

Dissertations

The dynamics of gas adsorption was studied in an air fluidized bed containing activated alumina particles. The adsorption studies made with a fixed bed and in the transition region between minimum fluidization velocity and 2.0 times minimum fluidization velocity, compliment work done at higher velocities. With adsorption, particle motion controlled the overall dynamics of the fluidized bed. A different approach in applying the two phase fluidization model was necessary to satisfactorily describe unsteady state adsorption in fluidized beds. Experimental and theoretical results were compared in frequency response plots to obtain a rigorous comparison. Good agreement was obtained for flow rates …

Correlation And Prediction Of Diffussion Coefficients In Binary Gas Systems, Raymond Gerald Bailey

Theses

A correlation was developed for estimating binary gas diffusion coefficients by the reference substance method, in this case using the viscosity of air and subsequently its corresponding temperature. The derivation was made by the linear least square analysis of 65 different binary systems comprising 161 separate data points at temperatures ranging from 193°K. to 1200°K. At any given temperature only the critical molal volume and the molecular weights of the two gases of interest are required to calculate the diffusion coefficient. The correlation based on the viscosity of air had an average error of 7.67%. The correlation using temperature had …

The Absorption Of Hydrogen Chloride From Dilute Air Mixtures, Edgar L. Demarest

Theses

A study was made of the absorption of hydrogen chloride from air mixtures containing from 1 to 40 mgm. HCl/liter (1000 to 40000 mgm./m.³), using a.4" diameter tower packed with 2" Intalox saddles, irrigated with water or with sodium hydroxide solutions of 0.3% to 3.8% concen?tration. Gas flow rates of 177 to 752 lbs./(hr.)(ft.²) were investigated at three liquid rates: 2960 ; 4260, and 5700 lbs./(hr/)(ft.²). All data were collected below the flooding point.

Correlations of the height of a transfer unit with the superficial gas velocity were prepared for water and for sodium …

A Digital Computer Simulation Of A Batch Or Semi-Batch Reactor, Robert Edward Viczorek

Theses

A digital computer simulation of a batch or semi-batch reaction was developed. The system consisted of a jacketed, agitated vessel equipped with a temperature controller modulating a control valve in the stream to the jacket. The reaction was liquid phase, and the jacket medium was liquid.

The program was written in a general form so as to be applicable to any liquid phase reaction with minimum modification.

A numerical technique was employed using initial values of the process variables in the first cycle of calculations for a time interval, and then using average values for further iterations. The simulation proceeded …

Heat And Mass Transfer In The Lyophilizatiuon Of Pharmaceuticals In Vials By Conduction Heating, William Warren Walsh

Theses

This thesis investigates the lyophilization of pharmaceuticals in vials by conductive heat transfer. The process phase diagram and methods of determining the solution eutectic temperature are reviewed. The theoretical considerations of heat and mass transfer pertaining to this process are discussed.

Lyophilization tests of distilled water and of mannitol solutions are used to indicate the relationship between vacuum chamber total pressure and the product/vial interface temperature. Experiments with 10% lactose solutions are used to determine the effect of shelf fluid temperature, product height and chamber vacuum on product/vial interface temperature. Test on a pharmaceutical product are used to confirm the …

The Transferability Of Force Constants Among Olefins, John Martin Comerford

Theses

A normal coordinate analysis of the in-plane vibrations of ethylene was performed using a modified valence force field, a modified Urey-Bradley force field and a hybrid orbital force field. The B_2u species of isobutene was also analyzed. An attempt was made to transfer force constants from ethylene and thereby solve the A₁ species of isobutene, but a solution could not be obtained. This suggests that simple transference of force constants is not feasable in this case.

The potential energy distributions obtained for ethylene are discussed. The normal coordinates calculated in this work are appended.

A Modified Redlich-Kwong Equation For Nonpolar And Slightly Polar Gases, David G. Skamenca

Theses

The PVT prediction capability of the Redlich-Kwong equation is substantially improved through the use of a generalized correlation based on the acentric factor. No experimental data is required to obtain the improved constants. Only the acentric factor and the critical properties of the pure gas are needed. The correlation of improved constants is limited to non-polar and slightly polar pure gases and mixtures in the supercritical temperature range.

The correlation applies to a reduced temperature range 1.00 le; T_R le; 1.60 and a reduced pressure range of 0.030 le; P_R le; 3.00. The correlation reduces deviations by as …

Non-Linear Analysis Of Electrocardiogram Tracings In Detection Of Occult Coronary Artery Disease, Joseph Robert Levitt

Dissertations

The general problem of identifying significant characteristics of a system by analyzing the properties of a signal emitted by that system is common to many disciplines, biological as well as physical. In general, achievement of a satisfactory solution depends on the capability of assigning membership of candidate signals to one of a number of mutually exclusive categories:

In this study, a new technique of processing the standard electrocardiograms from human subjects has been developed. This technique employs a set of non-linear transformations which enable the assignment of electrocardiograms into one of two Mutually exclusive categories. The first category is that …

Dynamic Stress Concentrations About An Epilliptical Discontinuity In An Elastic Solid, Kenneth Roy Schroll

Dissertations

The redistribution of dynamic stresses caused by the presence of an elliptical discontinuity in an infinite isotropic homogeneous elastic solid is examined. The solutions are obtained for the special cases of the rigid immovable inclusion and the vacuous cavity inclusion, and numerical results are presented.

The solutions to the wave equations in elliptical coordinates are expressed in series of the elliptical geometry eigenfunctions. Application of the boundary conditions, vanishing displacements for the rigid immovable inclusion and vanishing stresses for the cavity inclusion, yields in each case two infinite sets of linear algebraic equations for the expansion coefficients of the series …

Oscillations In Pulse Frequency Modulated Control Systems, Warren Joseph Guy

Dissertations

This dissertation is concerned with oscillations and their stability which occur in a control system containing two nonlinearities, separated by linear elements. Specifically the nonlinearities are Integral Pulse Frequency Modulators and the linear elements are described by ordinary differential equations which are linear. The IPFM can be modelled by a quantizer with hysteresis and many other PFM laws are related to IPFM, thus the study applies to more than just IPFM alone.

Boundaries on the system parameters are identified within which free oscillation may be possible. These boundaries give sufficient conditions for stability and necessary conditions for instability. Also since …

The Oxidation Of Sulfur Dioxide In A Regenerative Reactor, Raymond Henry Edgecomb

Theses

A novel dual-unit sulfuric acid converter is depicted that performs in cyclic operation in unsteady state. A mathematical model and IBM 1130 Computer program were developed to show the temperature and conversion profiles in commercial-sized vanadium oxide catalyst beds. In the catalytic oxidation of sulfur dioxide conversions of 95-97% were attained without benefit of conventional heat exchangers. A single exchanger operating in conjunction with the dual-unit system might attain conversions as high as 99%.

A Computer Program For The Optimization Of Binary Distillation In A Dual-Column System, Richard Vincent O'Lenick

Theses

A computer program is presented for the optimization of a two-column distillation system involving a two-component mixture. The economic reflux ratios in each column are determined using the McCabe-Thiele Method. Activity coefficients are computed by either the Wilson equation, the Margules equation, or both. The program is general and may be used for any binary system where the assumption of constant molal overflow is valid.

Options in the program permit use of either column in separate calculation schemes.

While the optimization effort was prepared in general terms, the initial work was directed toward the acetone-water system. Full data for this …

The Application Of A Non-Newtonian Rheological Equation To Low-Density Polyethylene, Jeffrey N. Goldstein

Theses

A generalized non-Newtonian equation describing the rheology of molten thermoplastics is verified for low-density polyethylenes. The equation is extended to account for both rheological temperature dependency and polyethylene molecular weight dependency. The prediction of the rheology of new polyethylenes without additional experimentation is thus possible.

The Computer Evaluation Of The Natural Frequencies Of Vibrating Circular Plates With Free, Fixed And Simply Supported Edges, Thomas Michael Juliano

Theses

The natural frequencies of the transverse vibration of a thin, isotropic, circular plate with free, clamped, and simply supported edge conditions were studied extensively. The frequency equation for each edge condition was derived from the classical partial differential equation of plate vibration. These equations, which are in terms of Bessel functions, were then solved numerically to find the natural frequencies. Since the accuracy of the Bessel function values is very important in evaluating these frequencies, a comprehensive digital computer program was devised to calculate these values to eleven digit accuracy. In this Bessel function program four different methods were required …

Simulation Of Periodic Tank Reactors, Noshir Pirojshaw Mistry

Dissertations

Normally it is assumed that the steady state mode of operation is most desirable for the design of the chemical reactor system. However it appears that this assumption may not be correct in many cases.

In the present work disturbances of various types were externally created and forced on a system comprising an isothermal continuous stirred tank reactor. The effects of these purposefully created disturbances were investigated by mathematically modelling the system and simulating it on a digital computer.

The change in reactor performance, as defined by the percentage change in the production rate from the steady state value, can …

Enthalpy Deviations For The System Methane - Carbon Dioxide, Fred S. Winter

Theses

Enthalpy deviations for the gaseous system, Methane and Carbon Dioxide were developed using the Redlich-Kwong equation of state. Values of enthalpy deviation were obtained at 0.0, 0.0852, 0.19912, 0.3583, 0.6685 and 1.0 weight fraction Methane, at temperatures of 100° F, 280° F and 460° F, at pressures between 200 and 10,000 PSIA.

A computer program in Fortran IV language was developed for solving the Redlich-Kwong equation in terms of the compressibility factor.

The Redlich-Kwong expression for enthalpy deviation, in combination with graphical methods was used to produce the results.

Rheology Of Asbestos Filled Polystyrene, Richard Henry Young

Theses

A capillary rheometer was used to generate data showing the volumetric flow rate at various pressures for a polystyrene resin and for an asbestos filled polystyrene. Variables evaluated were per cent asbestos and temperature. These data were then used to calculate the maximum shear stress at the capillary wall and the corresponding maximum velocity gradient (shear rate) at the capillary wall. A rheological equation containing three constants was employed to relate the shear stress to the shear rate. In addition, a simple relationship was found between the values of two of the constants and the per cent asbestos. There is …

Hypothetical Liquid Fugacity Coefficients, Douglas F. Patterson

Theses

The object of this thesis was to derive values of the hypothetical liquid fugacity coefficient of carbon dioxide for various temperatures and pressures. Most of the temperatures studied were above the critical temperature of carbon dioxide and thus carbon dioxide could not truly exist as a pure liquid. Hence the prefix "hypothetical" was used to acknowledge this apparent discrepancy. Carbon dioxide was purposely chosen for this reason. Also,the necessary data for carbon dioxide were generally more available than for any other normally gaseous solute.

The hypothetical liquid fugacity coefficients were derived from the published binary vapor-liquid equilibrium data of carbon …

The Effect Of Flow Rate And L/D Ratio On The Frequency Response Of Water Fluidized Beds, Arnold Ludke

Theses

In this investigation, the dynamics of a water fluidized bed with varying L/D ratio and flow rate were analyzed both theoretically and experimentally, and the results of the two were compared.

The theoretical analysis was based on the standard method of Laplace transforms and transfer function synthesis.

The experimental investigation was conducted using standard frequency response techniques.

The mathematical model used consisted of a series of non-interacting perfectly mixed cells plus a distance velocity lag.

At low flow rates (3 to 6 times minimum fluidization velocity) the experimental data (in the form of Bode plots) were found to be in …

Concepts In Lsi Servo-Control-Electronics, Alfons Alfred Tuszynski

Dissertations

This thesis deals with the engineering aspects of control electronics. It examines modern concepts of servo-control theory in the light of recent developments in the technology of monolithic circuits. Applicational considerations are slanted towards Aerospace standards of reliability and power-consumption economy.

Conclusions drawn from the discussion of fabrication constraints and performance requirements lead to a preference for digital implementations. Yield problems on one hand and aging effects on the other greatly reduce the feasibility rating of analog arrays.

Current practice in servo-control electronics revolves around purely analog implementations, sampled-data systems and Primitive on-off arrangements. The motivation behind the status quo …

A Rheological Equation Of State For Blood At Low Shear Rates, Anatoly Dritschilo

Theses

In this work a new rheological equation of state is presented and its application to blood is studied. The equation considered is a linear combination of Newtonian and non-Newtonian contributions to the apparent viscosity. The general form of the equation is

 T_ij =-(A + Be^{-1/C|(.5)Δi/j:Δj/i|1/2})Δij

Data from the literature were used to test the equation by generating curves of measured torque (T/L) versus applied shear rate (Ω) that would characterize the behavior of blood at all red cell concentrations and all shear rates in the Gilinson, Dauwalter and Merrill viscometer. The constants for the equation were …

Computer Specification Of Centrifugal Pump And Motor, Paul David O'Lenick

Theses

The purpose of this thesis is to develop a PORTRAIT computer program for selecting a centrifugal pump and motor driver. This is accomplished by means of generalized data which establishes the speed of the Dump and its power requirement. After selection of the pump, the motor is sized and specified. In addition to determining the pump and motor, the program also sizes the discharge and suction lines and the required control valve. The resulting solution yields the pump design data, motor, line and control valve sizes. From this data utility and relative equipment costs can be estimated.

Viscosity-Density Correlation Of Newtonian Liquids, Melvin Leonard Druin

Dissertations

The viscosity of monatomic liquids was modeled by an equation derived from the kinetic theory of gases. Viscosities may be calculated from data on density and molecular weight of the liquid. In adapting this relationship to polyatomic liquids, a single correction factor was developed for each of five series of homologues; n-paraffins, n-1 -alkenes, n-alkylcyclohexanes, n-alkylbenzenes and n-alcohols, to account for the deviations of the calculated viscosities from those reported, extending over a one- to three-hundred degree range. The factor is a function of reduced temperature relative to the normal boiling point, T_rB. A single equation for each …
