On the Dynamic Likelihood Approach to Data Assimilation for Stochastic Hyperbolic Geophysical Processes

Creator:

Foster, Dallas A.

Abstract:

Many geophysical phenomena exhibit complicated dynamics that, due to a variety of factors, diverge quickly from physical models. The arrival of new observations allows researchers to combine the model estimate with measurements in a statistical process called data assimilation to produce a revised estimate of the phenomenon. This assimilation of...

Structural Variations of Headwater Stream Food Webs Along Geophysical Gradients at the HJ Andrews Experimental Forest

Creator:

Zatkos, Lauren E.

Abstract:

The structure of food webs and how they relate to community stability has been an important debate in ecology. Specifically, predictability of web shape and how it influenced by surrounding landscapes is one of the main goals of such discussions. Headwater streams provide a study template that is of interest...

Branching Brownian Motion with One Absorbing and One Reflecting Boundary

Creator:

Felder, William F.

Abstract:

In this work we will analyze branching Brownian motion on a finite interval with oneabsorbing and one reflecting boundary, having constant drift rate toward the absorbingboundary. Similar processes have been considered by Kesten ([12]), and more recently byHarris, Hesse, and Kyprianou ([11]). The current offering is motivated largely by the...
