On the generalization of a time-to-response cancer risk assessment model
(1986)
This dissertation generalizes the hazard rate in the Hartley-Sielken model from a product form in dose and time to a nonproduct form. Also a latency period (the time from onset of cancer until it is clinically detectable) ...
Simulation of vehicular impacts with safety-shaped barrier
(1987)
In the research described here, a vehicle/barrier crush model was developed and combined with a vehicle model to simulate impacts with the concrete safety-shaped barriers (CSSB). The crush model accounts for the effects ...
Some problems in sequencing and scheduling utilizing branch and bound algorithms
(1988)
This dissertation deals with branch and bound algorithms which are applied to the two-machine flow-shop problem with sparse precedence constraints and the optimal sequencing and scheduling of multiple feedstocks in a batch ...
Evaluation of temperature, force, and chip formation in orthogonal turning of leaded brass
(1988)
The primary purpose of this research was to investigate the role of lead inclusions in leaded brass or free-machining brass on chip temperatures, cutting force, feed force and deformed chip thickness. The experiment was ...
A soil temperature model for predicting the overwintering emergence of Heliothis zea and Heliothis virescens (Lepidoptera, Noctuidae)
(1985)
An existing, physically based, one dimensional numerical model for soil temperature and soil water content was adapted and validated with experimental data on soil temperature in the upper 100mm of the profile. A simpler ...
Temperature distribution around a well during thermal injection and a graphical determination of thermal properties of the aquifer
(1980)
Analytical models of hot water injection into groundwater aquifers were developed in this study. Available analytical models of this problem assume that the caprock overlying the aquifer is of infinite thickness. However, ...
The linkage between the government and farm sectors : an analysis of the effect of farm policy on the U.S. economy
(1987)
The objective of this study was to specify the linkage between the federal government and the farm sector in the U.S. economy. The farm sector is the recipient of federal monies under legislated price and income support ...
Modeling transpiration and water use of ornamental plants during shipping and storage
(1986)
Experiments were conducted to predict transpirational water loss and duration of shipping/storage of Chrysanthemum morifolium under different temperatures and initial soil water levels. Transpiration rate, water potential, ...
The roles of perceived inhibitors and perceived facilitators in the pleasure travel destination choice process
(1987)
The purpose of this study was to identify perceived inhibitors and perceived facilitators in the pleasure travel destination choice process. A two stage travel destination choice model was developed based on the concept ...
Parameters to describe the growth of male cattle
(1987)
Parameters were estimated for nonlinear growth curves for bulls of five straightbred and 20 crossbred breedtypes produced in two generations of a diallel. The primary intent of this study was to use the estimates obtained ...
