The effect of shear on the thermal conductivity of non-Newtonian fluids
(1994)
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 ...
Dynamic soil pressures on deeply embedded structures
(1994)
The studies reported herein are motivated by the need to gain improved understanding of the response to earthquakes of deeply embedded and underground cylindrical tanks storing nuclear wastes, and develop rational but ...
Adaptive kernel density estimation
(1994)
The need for improvements over the fixed kernel density estimator in certain situations has been discussed extensively in the literature, particularly in the application of density estimation to mode hunting. Problem ...
A study of the impact of doubling carbon dioxide and solar radiation variations on the climate system
(1994)
The exchange of moisture and heat between the atmosphere and the Earth's surface fundamentally affect the dynamics and thermodynamics of the climate system. In order to trace moisture flow through the climate system and ...
A new simplified compositional simulator
(1994)
A new simplified fully implicit compositional simulator has been developed. This simulator is different from existing models because it combines the conventional black oil equations with a compositional injection component ...
Mechanisms of symmetric and asymmetric drainage of foam films
(1994)
The drainage of horizontal thin liquid films produced from aqueous solutions of ionic surfactants was studied experimentally, using videomicroscopy and interference techniques, for several surfactants in a wide range of ...
Prediction of magnetospheric parameters using artificial neural networks
(1994)
Artificial neural network models have been developed that provide the magnetospheric parameters Dst, polar cap potential and the midnight equatorward boundary of diffuse aurora. Layered feedforward neural networks have ...
Metabolic studies of Catharanthus roseus hairy root cultures by phosphorus-31 and carbon-13 nuclear magnetic resonance spectroscopy
(1994)
The regulation of primary metabolism and induction of secondary metabolism in Catharanthus roseus hairy root cultures were studied using noninvasive in vivo NMR spectroscopy. A micro-perfusion system was first developed ...
Manetho: Fault tolerance in distributed systems using rollback-recovery and process replication
(1994)
This dissertation presents a new protocol that allows rollback-recovery and process replication to co-exist in a distributed system. The protocol relies on a novel data structure called the antecedence graph, which tracks ...
A vision-based fuzzy logic and neural network approach to the control of hyper-redundant robot manipulators
(1994)
Hyper-redundant robot manipulators possess a very large degree of kinematic redundancy and are capable of motion similar to that of snakes and elephant trunks. Because of the computational burden required to calculate the ...
