Road users fail to realize their role in congestion. This thesis aims to calculate the appropriate charges required for users of I-495 - the Capital Beltway surrounding Washington, D.C. - in order to fulfill their portion of congestion costs. By developing a model from existing data that...

The primary objective of this study is to propose an estimator of the parameters of the generalized Gaussian noise model with desirable asymptotic properties, namely, asymptotic consistency and asymptotic efficiency. Three estimators are proposed and analyzed. The relative merits and demerits of...

This thesis introduces a new family of classifiers called dyadic decision trees (DDTs) and develops their theoretical properties within the framework of statistical learning theory.First, we show that DDTs achieve optimal rates of convergence for a broad range of classification problems and are...

Bayesian nonparametric methods are useful for modeling data without having to define the complexity of the entire model a priori, but rather allowing for this complexity to be determined by the data. Two problems considered in this dissertation are the number of components in a mixture model,...

Dynamic models, also termed state space models, comprise an extremely rich model class for time series analysis. This dissertation focuses on building state space models for a variety of contexts and computationally efficient methods for Bayesian inference for simultaneous estimation of latent...

This thesis describes research into business user involvement in the information systems application building process. The main interest of this research is in establishing and testing techniques to quantify the relationships between identified success factors and the outcome effectiveness of...

Many methods for highway cost allocation procedures have been adopted previously by all levels of government; local, state, and federal. However, they rarely address the issue of long span bridge allocation properly, simply treating these unique structures as the typical short span bridge. This...

To maintain a competitive edge, companies today must be able to efficiently allocate resources to optimally commit and fulfill requested orders. As such, order processing and resource allocation models have become increasingly sophisticated to handle the complexity of these decisions. In our...
