Bringing economic inequality into coupled economic-environmental models
Coupled economic-environmental models are cross-disciplinary tools that explore how economic activity interacts with the environment and vice versa. This thesis focuses on models that estimate the economic consequences of climate change, different greenhouse gas emissions pathways, and mitigation …

Land Use Variation on Mid-Columbia Plateau Upland and Lowland Archaeology Sites
… have interpreted artifact deposits in their environmental settings as evidence of human land use labeled as site types. Land use models consisting of cultural and environmental variables were developed from those studies. Those variables were compared to a sample of archaeological records …

Environmental and Statistical Performance Mapping Model for Underwater Acoustic Detection Systems
… manuscript describes a methodology to combine environmental models, acoustic signal predictions, statistical detection models and operations research to form a framework for calculating and communicating performance. This methodology has been applied to undersea target detection systems and has …

Rainfall patterns in a small-scale watershed based on NexRad and ground-based datasets
… in natural and anthropogenic stressors using environmental models require a realistic representation of probable rainfall in its most sensible spatial-temporal dimensions matching that of the phenomenon under investigation. As one of the most critical inputs in environmental models, rainfall …

Trajectory optimization for a fixed trim re-entry vehicle using direct collocation with nonlinear programming
… vehicle model is introduced and appropriate environmental models are chosen and implemented. Software is developed to discretize the optimal control problem using a direct collocation method. The resulting parameter optimization problem is solved using the MINOS non-linear programming …

Mid- to late Cretaceous Microbiostratigraphy, Palaeo-ecology and Palaeogeography of the Sergipe Basin, northeastern Brazil
… is documented and completely revised. Palaeo-environmental models, mostly derived from micropalaeontological and sedimentological criteria, are proposed for the distribution of the foraminiferal morphogroups. The palaeogeographic reconstruction of the studied area, from the upper Aptian to …

Doppler channel emulation of high-bandwidth signals
… emulator capable of applying, in real-time, environmental models to communications equipment in order to test the robustness of new wireless communications algorithms in development. Specific design goals for the new emulator included support for higher bandwidth capabilities than commercial …

Interpreting Global Emissions Scenarios into a Local Scale Urban Growth Model: Truckee Meadows Metropolitan Region, NV, USA
… future work to join SRES-linked urban growth and environmental models in order to conduct integrated climate change impact assessments at the local scale. Local scale analyses combining interrelated socio-economic and environmental issues will enable communities to make resilient plans which can …

A Framework for Site Analysis with Emphasis on Feng Shui and Contemporary Environmental Design Principles
… the site analysis process into different models, incorporates each model, and considers the interaction between them. The most important models are the environmental models (climate, geology, hydrology, topography, and vegetation models), social-cultural models, economic models, and …

Gestión del conocimiento en la generación de modelos ambientales
… The generation of environmental models is a Knowledge Management process, represented by means of interpretative structural modeling. It applies oriented graphs based on binary matrices of the interaction between elements linked by contextual causality relationships. …

Evaluation of environmental carrying capacity and application of the sustainability target method
The environmental carrying capacity (CC) is defined as the capacity of the earth to absorb or tolerate potentially stressful burdens imparted at various scales and locations, that is, to accommodate the ecological stresses without showing permanent damage. The CC can be used as a reference dataset …

Ensemble-characterisation of satellite rainfall uncertainty and its impacts on the hydrological modelling of a sparsely gauged basin in Western Africa
… temporal information to drive various downstream environmental models and early warning systems (EWS). However, when operating at higher spatial and temporal resolutions SRFE contain large uncertainties which propagate through the downstream models.This thesis uses the TAMSAT1 SRFE algorithm …

Agent-based models to couple natural and human systems for watershed management analysis
… expands conventional physically-based environmental models with human factors for watershed management analysis. Using an agent-based modeling framework, two approaches, one based on optimization and the other on data mining-are applied to modeling farmers' pumping decision-making …

Non-Linear Density Dependence in a Stochastic Wild Turkey Harvest Model
… (<I>Meleagris gallopavo silvestris</I>) harvest models assume density-independent population dynamics despite indications that populations are subject to a form of density dependence. I suggest that both density-dependent and independent factors operate simultaneously on wild turkey populations, …
