Design Of A Bit-Slice Processor, Kenneth Earl Green

Electrical and Computer Engineering ETDs

A microprogrammed computer processor unit is designed using bit-slice technology. This processor executes the PDP-11/45 instruction set. The performance is evaluated and compared to other existing processors.

State Estimation Using Parallel Extended Kalman Filters Of Nonlinear Measurements, Thomas Carlyle Sheives

Electrical and Computer Engineering ETDs

The extended Kalman filter applied to state estimation using nonlinear measurements has demonstrated divergence in many applications involving large initial uncertainties because of "invalid" linearizations performed by the filter on the nonlinear measurement functions. No quantitative results can be found as to how invalid these linearizations must be before divergence occurs. This report attempts to fill this void by deriving the extended Kalman filter as an approximate nonlinear least squares estimator, through the minimization of a measurement squared error function. The convergence of the extended Kalman filter is then determined by examining the squared error function and verifying the usefulness …

Calculation Of The Singularity Expanision Method Parameters From The Transient Response Of A Thin Wire, Kah-Song Cho

Electrical and Computer Engineering ETDs

The problem of determining the singularity expansion method (SEM) parameters from transient thin-wire data is exam­ined. A computer code is used to generate response data. The SEM parameters are computed from these data. For noisy data, it is shown that the parameter values can be improved by signal averaging.

A Tv-Calculator Teaching Aid System, Robert A. Pezzano

Electrical and Computer Engineering ETDs

A system is described in which calculations performed on an electronic calculator are displayed as an algebraic expression on a television or video monitor. A video module generates the timing signal for the video monitor and allows 16 lines of 16 characters to be displayed. The calculator module provides interfacing between the keyboard and display of a TI-59 calculator and the system. A computer module, containing a Z-80 microprocessor, interprets the calculator signals, simulates the calculator logic, and provides the video module with the information to be displayed.

A Numerical Investigation Of Nonlinear Resistance In Second-Order Autonomous Dynamic Networks, John Jerome Bornholdt

Electrical and Computer Engineering ETDs

Most approaches to the analysis of autonomous nonlinear networks fall under one or more of three categories: topological techniques, stability analysis, and approximate methods. The first method is universal, linear or nonlinear. The application of computer techniques has given strong emphasis to the latter. Approximate methods can give results on estimations of how net­work components affect stability.

This paper is an investigation of the stability of nonlinear resistance in autonomous dynamic networks through approximate methods.

A system that is both unforced and time-invariant is called autonomous. Linear autonomous networks lend themselves to general analytic solutions. With nonlinear autonomous networks, however, …
