The current study examined the transition region of axisymmetric isothermal and buoyant jets of low Reynolds number, directed vertically upwards into a stagnant, unstratified ambient. These flows were examined experimentally ...

A geometric nonlinear filter (GNF) is designed for application to the problem of tracking a maneuvering aircraft. The aircraft tracking problem is a state estimation problem and a state prediction problem. A nonlinear ...

The propagation of antiplane waves in an elastic solid containing a random distribution of cracks that are parallel to each other, and oriented at an arbitrary angle relative to the direction of the incident wave, is ...

Bioprocesses often require considerable expertise to insure proper operation and performance. However, they are also rich in both data and factual knowledge. Supervision and control can be improved by utilizing information ...

Nanoindentation is a widely recognized method for characterizing the mechanical properties of thin films and small volumes. This dissertation reports the results of finite element analyses of elastic and elastic-plastic ...

General problems of interest in computational fluid dynamics are investigated by means of optimization. Specifically, in the first part of the dissertation, a method of optimal incremental function approximation is developed ...

This work considers the effect of shear on the thermal conductivity of non-Newtonian fluids. These fluids display a variation of viscosity as a function of shear rate, and this study determines whether the thermal conductivity ...

An overview of two categories of numerical approaches to phase change problems, front tracking and fixed domain methods, is given. A further comparison of several fixed domain methods is made with some benchmark test ...

The objective of this research is to develop finite elements and iterative techniques for numerical solution of linear and nonlinear beam-on-foundation problems encountered in structural engineering. Although closed-form ...
