Short Time Spectrum Analysis-Synthesis Of Speech, Dusan Vujcic

Theses

This thesis presents an extensive study of the short time spectrum analysis-synthesis of speech. This type of speech processing attempts to synthesize speech without the short time Fourier transform phase information. Several existing analysis-synthesis methods are presented. In addition, five other methods are attempted experimentally. The results of these experiments are explained, identifying some very important properties of the short time spectrum analysis-synthesis. One of the methods was shown to synthesize a high fidelity speech. Finally, a comparison is made between this method and other known methods which are based on short time Fourier transform approach.

The Static Analysis Of A Complex Optical-Mechanical System Utilizing The Finite Element Method, Thaddeus A. Kciuk

Theses

This thesis utilizes the finite element method (MSC/NASTRAN) to perform an analysis on an optical-mechanical laser scanner used in the imaging industry. A Normal Modes analysis was conducted to determine the real eigenvalues and their associated eigenvectors. The results of the analysis (modal frequencies and modal shapes) were then compared with empirical data measured using a FFT (Fast Fourier Transform) analyzer with modal software (Hewlett Packard 5423A Dynamic Signal Analyzer). The dynamic characteristics of the system optical output beam and optical components were evaluated by simulating the optical components using rigid bar elements. A modal frequency response analysis was performed …

Criteria For Selecting Materials Suitable For Application To Modified Atmosphere Packaging Of Fish, Yvonne Allen

Theses

The process of preservation is an important step in stabilizing perishable items in order for them to withstand distribution, handling, and storage. Preservation can be achieved by several methods, but the method of concern in this paper is that of modified atmosphere storage which is reported to extend the shelf-lives of perishable products. Studies on modified atmosphere storage have emphasized the preservating action of carbon dioxide (CO2) in reducing (1) the extent of microbial spoilage, and (2) the tissue pH of the products so stored in comparison to those stored aerobically. Low tissue pH creates unfavourable environment which negatively influences …

A Student Scheduling System For A Microcomputer, Michael Mahaney

Theses

This student scheduling system was written for use on a microcomputer to give the local high school more control over the scheduling process. Scheduling systems are used by high schools to schedule their students, balance classes, and print student schedules and class lists. A scheduling system must be flexible to provide for the generation of many different types of schedules. Most scheduling programs currently used are shared by high schools through the use of BOCES (Board of Cooperative Educational Services). Schools send their schedules to the BOCES regional computer centers to be run on mainframe computers. This scheduling system was …

Mobile Telephone System And Non-Wire Line Network, Daniel Chi Man Cheung

Theses

The need to communicate with non-fixed points without the use of wires led to the development of mobile telephone systems in the early 1920's. Since then, the expanding need for mobile phone service and resulting growth have led to the development of the Advanced Mobile Phone Service (AMPS) by the Bell System. This thesis describes the AMPS system and explains how service is provided to mobile units roaming in a typical area of up to 25 square miles. A network is proposed to interconnect service areas to expand the coverage to a much larger geographic area. Efficient use is made …

Development Of Dynamic Testing Machine For Laboratory Modeling Of The Rock Fracturing Phenomenon, Mohammad Ali Moghaddass Zadeh Kermani

Theses

The purpose of this thesis is to develop a dynamic testing machine for laboratory modeling of the rock fracturing phenomenon. Bearing stratum fracturing is a construction difficulty which occurs when end-bearing piles are driven to weak rock or weathered sound rock. It is a pile group effect and can result in significantly less pile carrying capacity than the final driving resistance would normally indicate.

A linear scaling factor was derived to establish similitude between the laboratory apparatus and field conditions. This scaling factor is approximate and was used for overall sizing of the apparatus and its components. A more exact …

A Study Of The Relationship Of Sheffield & Igt Methods For Determining Paper Smoothness And Their Ability To Predict Gravure Printability, Austin Sung

Theses

A variety of methods have been devised for the measurement of the smoothness of paper. These are reviewed and summarized in this work. Of the available methods, two of the most widely used have been selected for study. The air-leak method exemplified by the Sheffield instrument, and the nip-spreading method of the IGT printability tester are specifically presented and performed. The data obtained in empirical experiments are statistically analyzed and plotted, so as to determine if there is a functional relationship between the responses of these two methods. A linear relationship between the two is shown to be an appropriate …

Non-Linear Principal Component Analysis (Approximation By A Second-Order Taylor Series), John Viggiano

Theses

Linear Principal Component Analysis (LPCA) has been applied in multivariate analysis because of its many optimality properties. However, when applied to locate singularities in a set of data, LPCA is only able to locate linear singularities. If the problem being considered tends to produce variables with non-linear relationships, such as with non-linear regression, LPCA is necessarily of limited utility in identifying singularities. Non-linear generalizations of PCA have been suggested in the literature. Essentially, these involve augmenting the data with higher-order terms, in particular square and cross product terms, and running a LPCA on the augmented data set. The problem with …

Synthesis And Characterization Of Poly(Imide-Sulfonamides), Eric J. Kuckhoff

Theses

The objective of this research project was to synthesize and characterize eight novel copoly(imide-sulfonamides) 1, 2, where R was 4,4'-oxydianiline, 4,4' -methylene dianiline, 4,4'-diamino diphenyl sulfone, and 1,12 diaminododecane, respectively. After synthesis, these eight polymers were characterized by dilute solution viscosity, infrared spectroscopy, thermal gravimetric analysis, and differential scanning calorimetry. Prepared polamic acids of copoly(imide-sulfonamides) were cast on glass plates and thermally cured to give films which would be evaluated for reverse osmosis and hyperfiltration. *Please refer to full-text for relevant diagram

An Airborne Thermal Remote Sensing Calibration Technique, I. D. Macleod

Theses

A calibration technique for airborne thermal remote sensing systems without the requirement for ground truth or multiple altitude measure ments is developed and evaluated. This technique is based on vertical and offset look angles and in effect corrects for image degradation due to atmospheric effects . The results were evaluated by comparison to a multiple altitude regression technique using previously generated imagery, and by statistical methods, including an error analysis. Assuming that the multiple altitude regression technique was exact, the error on apparent temperature produced by this angular technique was 0.32C.

Design Of A Photoreactor For The Oxidation Of Toxic Pollutants In Water By Ozone And Ultraviolet Radiation, Andrew Youngrak Park

Theses

A photoreactor has been set up to study the feasibility of ozone and ultraviolet radiation for treating pollutants in water. Phenol, 2,4-dichlorophenol, and 2,6-dichlorophenol were chosen as pollutants in this study.

Contaminant Transport Against A Slowly Moving Fluid : An Experimental Investigation, Surya Man Shakya

Theses

Leachate migration into groundwater from leaking lagoons, hazardous waste sites, solid waste disposal sites, etc. has recently become a major cause of groundwater pollution. A possible solution to prevent leachate migration into groundwater is to create a negative hydraulic gradient toward the site. This can be achieved by installing two parallel slurry trench cut-offs around the perimeter of a leaking lagoon and by filling it with water. The water und-er the influence of positive hydraulic gradient will move toward the site and will finally find its way on the surface of the lagoon. Along with the flow of water, the …

A Comparison Of The Biodegradation Of Nitrobenzene, 1-Butanol, And 2,4-Dichlorphenoxyacetic Acid Using A Municipal Mixed Liquor And Three Commercial Bacterial Preparations, Salvatore P. Salerno

Theses

The biological degradation of nitrobenzene, 1-butanol, and 2,4-dichlorophenoxyacetic acid (2,4-D) was studied in aerated 6 liter batch reactors using activated sludge from the Livingston, NJ wastewater treatment plant-- by itself and in a 10:1 by volume mixture with each of three commercial bacterial preparations: Hydrobac, BI-CHEM DC-1006/7, and Liquid Live Microorganisms (LLMO). Air stripping and adsorption were determined to be insignificant removal mechanisms for the three compounds studied. None of the bacterial mixtures were able to degrade 10 ppm nitrobenzene to any significant extent. A small but noticeable improvement in degradation rates occurred when the Livingston sludge was mixed with …

Application Of Least Square Cubic Splines To The Analysis Of Edges, Roland Walter Porth

Theses

A technique using least square cubic splines was developed to obtain an estimate of the MTF from edge response measurements. By making specific assumptions concerning the general nature of edges to be analyzed, an optimized procedure was developed to fit noise free cummulative gaussian edges. The procedure was evaluated using simulated data from various spread function shapes and levels of additive noise. The spline technique produced MTF estimates which had less bias and lower variance than the commonly used derivative - transform technique. Due to the various constraints which can be imposed on the spline, least square cubic splines actually …
