GEOCOM is a model developed to evaluate the cost effectiveness of alternative technologies used in the completion, production, and maintenance of geothermal wells. The model calculates the ratio of life-cycle cost to life-cycle production or injection and thus is appropriate for evaluating the...

The impacts of completion practices on production and maintenance costs are considered. To evaluate alternative completion and workover technologies, a simple model has been developed that compares total well cost to total production or injection. The model is discussed briefly and results from...

Many human papilloma virus (HPV) types are sexually transmitted and HPV DNA types 16, 18, 31, and 45 account for more than 75% if all cervical dysplasia. Candidate vaccines are successfully completing US Federal Drug Agency (FDA) phase III testing and several drug companies are in licensing...

We analyze a multi-sector growth model with directed technical change where man-made capital and exhaustible resources are essential for production. The relative profitability of factor-specific innovations endogenously determines whether technical progress will be capital- or...

This thesis focuses on the developing of statistical methodology in reliability and quality engineering, and to assist the decision-makings at enterprise level, process level, and product level.In Chapter II, we propose a multi-level statistical modeling strategy to characterize data from...

The use of computer modeling is fast increasing in almost everyscientific, engineering and business arena. This dissertationinvestigates some challenging issues in design, modeling andanalysis of computer experiments, which will consist of four majorparts. In the first part, a new approach is...

This thesis consists of two related parts. In the first part we conduct an empiricalexamination of the dynamics of Australian interest rates of six different maturities,covering the whole yield curve. This direct study of the long rates is quite novel. Weuse maximum likelihood estimation on a...

Existing credibility models have mostly allowed for one source of claim dependence only, that across time for an individual insured risk or a group of homogeneous insured risks. Numerous circumstances demonstrate that this may be inadequate and insufficient. In this dissertation, we developed a...

An overview of modern and historical interest rate model theory is given with thespecific aim of derivative pricing. A variety of stochastic interest rate models arediscussed within a South African market context. The various models arecompared with respect to characteristics such as mean...

The twenty-two papers collected in this volume illustrate the itinerary of Henry Tulkens, an applied theorist, on the occasion of his retirement from teaching. The collection is structured in four parts: I. Decentralized resource allocation processes for public and private goods - II....
