This thesis is composed of four parts: i) system
description, ii) model development, iii) parameter
estimation, and iv) validation. The natural system used
here is an aspect of the immune system, namely, the
distribution of recirculating lymphocytes in various
organs throughout the body. This distribution gains
importance because: i) it...
This thesis is concerned with developing techniques for identifying "superior" Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) parent trees based on seedling progeny evaluation. The growth responses of up to 14 open-pollinated families to shade, drought, and stand density were assessed in four experiments. A technique was developed to compare family height...
A semi-empirical mobility model is presented which predicts tracked vehicle performance in timber harvesting applications. The interactions between the log load and the
terrain, the log load and the vehicle, and the vehicle and the terrain cause resistances for the vehicle. The mobility
model calculates these resistances, comparing them to...
Large digital computer reactor fuel performance codes
perform repeated calculations of temperature profiles
during transients. The thermal response is required to
calculate the mechanical behavior. This mechanical
response in turn feeds back to the thermal calculations
through mechanisms such as fuel swelling or shrinking,
causing changes in the fuel-clad gap...
