The prediction and measurement of incompressible flow in a labyrinth seal
(1986)
A computational/experimental study was conducted on the incompressible flow in a labyrinth seal at a variety of leakage rates and seal rotation rates. The predictions were obtained using a finite difference code that ...
An optimal gain adaptive control system for CNC metal cutting machine tools
(1986)
The optimal gain adaptive control system described in this dissertation is a nonlinear, sampled data system which is designed to regulate the cutting force during turning operations. The controller is designed to keep the ...
Capillary performance and heat transfer charateristics of the evaporating thin liquid film in a triangular micro groove
(1995)
For the capillary flow in a groove channel, the analysis of axial variation of the intrinsic meniscus as well as that of evaporating thin film region was carried out. Various approximate analytical solutions were developed ...
Tilt pad bearing effects on rotordynamic stability and improvements in global system dynamic analysis
(1989)
A general method of incorporating pad flexibility effects into isothermal tilting pad bearing analysis is developed. The pad assembly approach is extended using two-dimensional finite elements to determine pad deformations ...
Synthesis of compensators for non-overshooting step responses
(1992)
In many physical systems, a non-overshooting step response is often desirable if not required. Presented in this dissertation is a general design methodology for synthesizing compensators for a non-overshooting step response ...
A design methodology for synthesizing low order robust controllers for flexible structures
(1992)
In this research, a design methodology is developed for realizing low order robust controllers for flexible structures modelled as partial differential equations (PDEs). The efficacy of the methodology is illustrated by ...
Nonlinear dynamic system identification using recurrent neural networks
(1993)
The objective of this research is to develop a nonlinear empirical model structure and an associated parameter estimation algorithm based on artificial neural networks (ANNs), and to further use it for the identification ...
Modeling delamination characteristics and influence in a laminated plate with a part-through hole
(1993)
A laminated composite pressure vessel subjected to a concentrated laser ablation process has been investigated. The primary goal of this research was to investigate the role of delamination in the failure process. A layered ...
Experimental studies of radiation transmission in water and numerical simulation of dynamic behavior of a salt-gradient solar pond
(1993)
The development of salt-gradient solar pond modeling has been reviewed and categorized into the six submodels. These models are summarized in tabular form, and the recommendations are provided for continuing areas of ...
