Optimal commercial fishery management sustains each salmon species' population while maximizing economic benefits. This thesis addresses two questions. What are the Alaska Department of Fish and Game's and the Board of Fisheries' intentions when conducting a fishery management plan in Upper Cook Inlet? How does it compare to its implementation?...
This paper reports on the valuation of the marine halibut and salmon sport fishery of central and lower Cook Inlet, Alaska. The project was designed to simulate changes in economic value and regional economic impacts for environmental analysis but has also been used in fishery allocation management. This study develops...
General population stated preference surveys are generally drawn from random samples that typically contain a large number of urban households relative to rural households due to the spatial distribution of populations. Given this, it is important to understand and assess whether differences in the preferences and values these two populations...
Polybenzimidazoles were synthesized from 3,3'-diaminobenzidine (DAB) and dicarboxylic acids. The polymerizations using the dicarboxylic acid monomers were carried out in polyphosphoric acid (PPA) and phosphorus pentoxide/methansulfonic acid (PPMA) which acted as the solvent and condensing agent. The resulting polybenzimidazoles had inherent viscosities in the range of 0.12 to 0.84 dL/g....
In this paper we describe a fuzzy logic based control system implemented on a PC architecture. The rule based inference engine of this expert system is easily configured through an ascii text file and is demonstrated to be capable of controlling various simulations, including an inverted pendulum. The controller is...
Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...

In this thesis the concept of inhomogeneous
dielectrics is demonstrated for various optical coating
applications. Compositionally-varying silicon oxynitride
(SiON) dielectric layers, with the refractive index
varying as a function of position, are grown by computer-controlled
plasma-enhanced chemical vapor deposition
(PECVD) using silane, nitrogen, and nitrous oxide reactant
gases. Compositionally graded...
Coho salmon (Oncorhynchus kisutch) were exposed to sublethal levels of a water-soluble fraction (WSF) of Cook Inlet crude oil for periods ranging from 18 to 31 days, at four acclimation temperatures. The fatty acid composition of phospholipids extracted from muscle, gill, liver, and brain tissues, and, at three of the...
