Modeling Geographic Population Dispersion Utilizing Geospatial Information System Environment Agents In An Agent Based Model, Karl D. Liebert

Computational Modeling & Simulation Engineering Theses & Dissertations

New capabilities in agent based model (ABM) environments are opening the door to the creation of ABM that may incorporate high-quality, real world environment data in the form of Geospatial Information System (GIS) files . In the past, GJS environments were only possible through extensive software development efforts focused on specific model applications.

This thesis explores the value and issues of using GIS data to provide an ABM environment. It examines the ability of ABM development environments (DE) to support GIS environment data. The selected ABM DE is then used to model population behavior in an environment defined by authoritative …

Spatial Analyses And Repletion Of Gargathy Coastal Lagoon, Loreto Herraiz Gomez

OES Theses and Dissertations

Coastal lagoons and bays vary in shape and size in response to antecedent topography, geologic processes and sea level rise. Variations in shape and environmental conditions of coastal basins are believed to influence the distribution of benthic sub-environments and the exchange of water with the ocean and other adjacent coastal systems. Gargathy Inlet and its coastal lagoon vary spatially from the inlet, where the greatest depths are observed, to the mainland, dominated by shallow intertidal areas, colonized by marsh. Hypsographic and hydro-hypsographic analyses of Gargathy's coastal lagoon were the primary techniques applied to understand the relative distribution of the benthic …

The Return Of Russia: Energy's Superpower Or Potemkin Village?, Greg R. Bayes

Graduate Program in International Studies Theses & Dissertations

George Kennan's prediction of the Soviet Union's downfall may have, in retrospect, jinxed Russia on the one aspect that had historically worked in its favor: time. The confluence of time and space--brought about by an emphasis on territorial expansion-had greatly aided Russia when difficulties had rendered the variable of time indispensable. When confronted by the likes of Napoleon and Hitler, for example, Russia had at its disposal the luxury of always trading space for time. Although deprived of its empire, the issue of space is not an overarching concern for a Russia that today still spans from Vladivostok to St. …
