Pattern recognition of speech using hybrid computer feature extraction

Creator:: Herr, Alan Jack
Abstract:: Most technological problems associated with man-machine conversations have been solved and are well documented in both the contemporary technical and lay literature. The major remaining technological problem is the real time conversion of a human's vocal uterances into a "written" phoneme sequence representing the information content of speech. The work...

A dynamic model of exchange rate in relation to international trading

Creator:: Sun, Keong-wah Gary
Abstract:: It is popular belief that the volatility of the exchange rate is due to the balance of payments, which in turn is mainly influenced by the balance of trade. A closed-loop dynamic economic model is proposed to describe and analyse the effect of the international trade of a country on...

Theoretical influence of untransposed transmission line construction on system losses and voltage balance

Creator:: Chanakorn, Chavalit
Abstract:: The purpose of this thesis is to investigate the necessity of transposition in the construction of overhead transmission lines. Line currents, line voltages and line losses of both the transposed and untransposed lines were calculated and compared for two different voltage classes. The conventional method of symmetrical components was used...

A parametric analysis of the capabilities of undersea acoustic imaging

Creator:: Calligan, C. C.
Abstract:: The feasibility of utilizing acoustic imaging techniques for improving the undersea viewing capability of small submersibles is investigated. The limiting values of major parameters in acoustic imaging systems are established and graphs which illustrate the parametric relationships are presented. A series of sample calculations illustrate how the graphs can be...

Digital model of a synchronous generator excitation system

Creator:: Ramchandani, Hiranand Balchand
Abstract:: This thesis develops a simplified and logical simulation model for an amplidyne excitation system for a synchronous generator with an automatic voltage regulator. The non-transfer function representation using field determined parameters including variable inductance and machine saturation was used to reduce the computing time for the stability analysis. The simulation...

Liquid crystal thermography : a new system for breast cancer detection

Creator:: Bichara, Kamal Fouad
Abstract:: A liquid crystal thermographic technique was developed for application to several problems in clinical medicine and physiology. The procedure was inexpensive, rapid, simple, versatile and acceptable to patients. Investigators in the past have used cholesteric liquid crystals for thermography but their use was limited to research in the medical field...

The identification of Dungeness crab from the power spectral density function of their acoustic signature

Creator:: Eghbali, Hassan J.
Abstract:: The power spectral density of the acoustic signature of Dungeness crab was calculated by the use of digital computer. The signal produced by the Dungeness crab was an analog signal. Therefore a conversion of the signal from analog to digital was necessary. This was done by sampling the acoustic signature...
Resource Type:: Masters Thesis

A computer controlled robot analyzer for in situ water quality monitoring

Creator:: Birch, Kenneth Norman
Abstract:: A new, computer oriented system for automatic, in situ monitoring of water quality is proposed which makes full and effective use of modern computer technology. The main objective of this thesis work was the development of the concept for in situ computer controlled experimenting as a reasonable and effective means...
Resource Type:: Masters Thesis

An eraseable MOS read-only memory

Creator:: Johnson, Norman Leland
Abstract:: A non-volatile electrically alterable read-only memory using an MOS field effect transistor with a threshold voltage which depended upon the position of ionic charges for its memory was fabricated. The conventional silicon dioxide layer was replaced by a composite layer consisting of thermal silicon dioxide, electron beam evaporated aluminum oxide,...

Resource Type:: Dissertation

Investigation of electric field-induced optical absorption changed in CdS

Creator:: Shimoda, Raynor Yoichi
Abstract:: The feasibility of using the Franz-Keldysh effect in practical light intensity controlling devices was investigated. Reverse-biased diodes made from CdS were implemented to obtain high electric fields necessary for the effect. The three types of diodes studies were: MIS, metal-semiconductor barrier, and p⁺-n heterojunction. An expression for the change in...

Radiation losses in microstrip circuits

Creator:: Lo, Sui-Sang
Abstract:: The purpose of this study is to investigate radiation losses in microstrip circuits. Expressions are derived to evaluate the radiation resistances (or conductances) for single terminated, open and short-circuited lines. The quality factor Q of open and short-circuited stubs is evaluated. An analytical procedure is formulated to evaluate the radiation...

The design of an interface between IEEE standard bus and unibus-CP1100/GPIB interface

Creator:: Aghdasi, Farhad
Abstract:: CP1100/GPIB Interface is an interface between the "General Purpose Interface Bus", which is an implementation of the Universal Bus described in IEEE Standard 488-1975, and Unibus. This interface enables TEKTRONIX CP1100 series controllers to operate GPIB- compatible instruments connected to the General Purpose Interface Bus. The designer can now incorporate...

REGTRAN and MICRO, the implementation of two digital system simulators

Creator:: Baheti, Padma R.
Abstract:: REGTRAN (REGister TRANsfer), a hardware description language and SYSSIM (SYStems SIMulation), a simulator for the system described by REGTRAN were originally developed by Edward Pett, Jr [33] at the University of Texas at Austin. These two programs are successfully used to simulate many digital systems of complex nature. It is...

Multiple-output combinational network minimization

Creator:: Lin, Pʻei-chen
Abstract:: An important step in the design of digital networks lies in the derivation of the switching formulas which describe the combinational logic networks in the system. In most large systems the number of gates and the number of connections are major factors that affect the cost of the system. An...
