  • 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...

  • Design of a mini-computer controlled digital integrated circuit tester

    Creator:
    Fasang, Patrick Pad, 1941-
    Abstract:
    The purpose of the thesis is to design, construct, program, and test an automatic integrated circuit test system. The class of integrated circuits tested was restricted to digital integrated circuits. The general concept of testing a digital integrated circuit is based on the truth table of that circuit. A combination...

  • 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...

  • 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...

  • 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,...

  • 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...

  • 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...

  • 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...

  • 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...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...
