Semi-discrete Galerkin solution of the compressible boundary-layer equations with viscous-inviscid interaction
A method is developed to solve the two-dimensional, steady, compressible, turbulent boundary-layer equations and is coupled to an existing Euler solver for attached transonic airfoil analysis problems. The boundary-layer ...
The application of feedforward artificial neural networks to function approximation and the solution of differential equations
The increasing use of artificial neural networks and other connectionist systems in engineering, and the advantages obtained from that use, motivated the development of an approach wherein a single or multiple input ...
Evaluation of superelastic nitinol as a shielding material for hypervelocity impact
Superelastic Nitinol Shape Memory Alloy (SMA) as a shielding material for hypervelocity impact is investigated. Impact peak pressures from Rankine-Hugoniot equations and empirical figures of merit, which give a general ...
Change detection using types for non-stationary processes
Space shuttle operation requires the monitoring of a large number of stationary signals in the search for "anomalies." This problem amounts to determining whether a change has occurred in a signal having a partially known ...
Two-stage ARMA spectral and bispectral modeling with application to space shuttle flight data
Parametric models for the representation of the power spectrum and bispectrum of a bank of data by the use of a two-stage, auto/cross-correlation matching (ACM) technique are developed. First, the applicability of the ACM ...
Genetic algorithm tuning of a fuzzy logic controller for a dynamic system
This thesis describes the use of the genetic algorithm to facilitate the design process of a fuzzy logic based controller. The basic mechanics of both the fuzzy logic control system and the genetic algorithm are presented ...
