Measurement Of The Surface Energy Of Rock By The Three-Point Bending Of Notched Beams, John Walter Corwine
Measurement Of The Surface Energy Of Rock By The Three-Point Bending Of Notched Beams, John Walter Corwine
Masters Theses
"In this investigation, the surface energy of a medium-grained igneous rock (Barre granite) was measured by breaking small, notched beams in bending. The technique was adapted from fracture toughness tests that have been used with metals and ceramics. The equations used for the calculation of surface energy were derived from several writers' equations for the stress intensity at the end of a notch in a beam subject to bending. Beam thickness, notch width and mineral occurring at the notch tip were evaluated for their influence on the calculated values of surface energy. The surface energy values obtained were used in …
Vibration Of A Rotating Cantilever Beam With An Independently Rotating Disk On The Free End, Darrell Blaine Crimmins
Vibration Of A Rotating Cantilever Beam With An Independently Rotating Disk On The Free End, Darrell Blaine Crimmins
Masters Theses
"This thesis provides a vibration analysis of a rotating cantilever beam with an independently rotating thin circular disk on the free end. The exact differential equations of the system as defined by classical Bernoulli-Euler beam theory are written using the methods of the calculus of variations. The exact equations are not solved, but two different approximations are found by assuming a cubic polynomial deflection curve and applying the equation of Lagrange. The solutions are restricted to small deflections of the beam and a shaft stiffness which permits a deflection in only a single plane. Nonlinear differential equations result in the …
An Analysis Of A Quadrature Double-Sideband/Frequency Modulated Communication System, Denny Ray Townson
An Analysis Of A Quadrature Double-Sideband/Frequency Modulated Communication System, Denny Ray Townson
Masters Theses
"A QDSB/FM communication system is analyzed with emphasis placed on the QDSB demodulation process and the AGC action in the FM transmitter. The effect of noise in both the pilot and message signals is investigated. The detection gain and mean square error is calculated for the QDSB baseband demodulation process. The mean square error is also evaluated for the QDSB/FM system. The AGC circuit is simulated on a digital computer. Errors introduced into the AGC system are analyzed with emphasis placed on nonlinear gain functions for the voltage controlled amplifier"--Abstract, page ii.
Digital Simulation Of A Costas Loop Demodulator In Gaussian Noise And Cw Interference, Ajay Mugatlal Mehta
Digital Simulation Of A Costas Loop Demodulator In Gaussian Noise And Cw Interference, Ajay Mugatlal Mehta
Masters Theses
"A digital computer model of a Costas loop has been employed to study the effects of Gaussian noise and continuous-wave interference on the detection of biphase modulated signals. The dependence of bit-error probability, mean-square error between input and output, phase-error variance and threshold on signal-to-Gaussian-noise power ratio, interference-to-Gaussian-noise power ratio and frequency offset of the interference have been investigated and compared with previously obtained experimental results. The model has been verified for its accuracy in the case of no noise and when Gaussian noise is present at its input"--Abstract, Page ii.
The Lund Ash-Flow Tuff, John Evans Kreider
The Lund Ash-Flow Tuff, John Evans Kreider
Masters Theses
"The Lund Ash-flow Tuff is the uppermost member of the Needles Range Formation, located in southwestern Utah and eastern Nevada. This member can be correlated over an area of several thousand square miles. A detailed study of petrographic and physical features of the Lund show vertical and lateral variations in mineral content and welding intensity. Vertical differences are related to changes in the magma chamber during the Lund eruption interval. Several different ash-flows make up the Lund member. All mineral concentrations vary laterally, with concentration decreasing away from the center of the Lund field. Vertical and lateral variations in physical …
Statistical Estimate Of Positional Error Inherent In Very Low Frequency Radio Navigation (Range-Range), Jimmie D. Mcginnis
Statistical Estimate Of Positional Error Inherent In Very Low Frequency Radio Navigation (Range-Range), Jimmie D. Mcginnis
Masters Theses
"To determine the effectiveness of Very Low Frequency (VLF) navigation in certain areas of the world, it is necessary that a method be developed to estimate the positional error associated with VLF relative positioning techniques. This paper presents a method which consists of a least-mean-squared procedure to sum up the errors contributed by each station being monitored. Since phase jitter (i.e., phase fluctuation) is a random variable, a statistical approach is employed to produce a one Σ ellipse centered about the true position. In short, this method defines the size and orientation of an area called an error ellipse which …
The Cathodic Reduction Of Bromate Ions On Mercury In Neutral And Basic Solutions, Jaw-Shin Chang
The Cathodic Reduction Of Bromate Ions On Mercury In Neutral And Basic Solutions, Jaw-Shin Chang
Masters Theses
"The reduction of BrO⁻₃ was studied in neutral and basic solutions on a stationary Hg surface under activation controlled conditions. Coulombic efficiency studies showed that BrO⁻₃; was reduced to Br⁻ with high efficiencies. The polarization measurements lead to a proposed reaction scheme which is consistent with the experimental observations"--Abstract, page 1.
An Approximate Min-Max Solution To The Identification Problem, Richard Loyd Warren
An Approximate Min-Max Solution To The Identification Problem, Richard Loyd Warren
Masters Theses
"A technique based on the min-max error criterion is proposed for identifying a dynamic system in terms of a discrete-time model from the system response to a deterministic input. A linear, single-input/single-output, lumped-parameter, time-invariant (at least during the measurement interval) system is assumed. Although the resulting problem is non-linear, it is shown that linear programming techniques are applicable if a realistic approximation is made. The technique is implemented on the digital computer and evaluated by considering a number of typical discrete-time systems. The effects of additive noise are also considered"--Abstract, page ii.

A Digital Simulation For Optimum Nonlinear Detection Of Binary Signals In Impulsive Noise, Ralph Bernard Fluchel
A Digital Simulation For Optimum Nonlinear Detection Of Binary Signals In Impulsive Noise, Ralph Bernard Fluchel
Masters Theses
"The problem of reducing the effects of impulsive noise on binary communication systems is considered. A digital simulation of such a system is developed in order to find a nearly optimum (minimum probability of error criterion) nonlinear device to precede detection. The level of the Gaussian noise power is found to be the most important parameter for determining the nearly optimum nonlinear device"--Abstract, page ii.
Digital Simulation Of A Signal Conditioner/Bit Synchronizer, Quentin Reed Webb
Digital Simulation Of A Signal Conditioner/Bit Synchronizer, Quentin Reed Webb
Masters Theses
"A bit rate filter type signal conditioner/bit synchronizer used in a split-phase PCM system is modeled digitally in three stages to determine overall system performance. General computer algorithms are developed to approximate independent operation of each major segment within the device. Bit rate effects and signal time-base error are investigated yielding the characteristic G-curves for the phase detector. These characteristics facilitate subsequent analysis of a linear equivalent digital-data-transition tracking phase-locked loop under several typical time-base error input conditions. Using bit error probabilities as performance criteria, the conditioner/synchronizer is found to perform adequately at signal-to-noise ratios exceeding +10dB. For inputs below …
