A dual-diffusion model for influenza transmission, control, and prevention in the urbanized area of Buffalo
(2010)
The diffusion of influenza disease and that of individual preventive behavior are intrinsically interrelated. This dissertation presents an original dual-diffusion model to couple these two diffusion processes together. ...
Spatial-Temporal Analysis and Modeling for Prenatal Exposure: A Case Study of Erie County, New York
(2014)
According to the US Department of Health and Human Services, there were approximately 3.95 million births of babies in United States' hospitals in 2012. During each of these pregnancies, the maternal body and the developing ...
Modeling the Dynamic Complexities of the Urban Food Environment to Improve Access to Healthy Foods
(2012)
Many low-income households in cities lack spatial and economic access to vendors that sell high quality and nutritious healthy foods, like fresh fruits and vegetables. This lack of access makes it difficult for low-income ...
Modeling nonlinear sorption of trichloroethene in natural sorbents with kerogen
(2012)
In the subsurface, chlorinated solvent sorption to aquifer materials hinders remediation efforts and makes predicting the transport and fate of chlorinated solvents in groundwater a nontrivial enterprise. Due to heterogeneity ...
Incorporating Advancements in Science, Technology, and User Demands into State-of-the-Art Earth-Systems Modeling to Empower Novel-GIS Users in Natural Resource Decision Making: A Geographic Information Systems Perspective
(2012)
The scientific and technological world we live in is constantly changing; as our methods evolve, the discoveries we make brings new advancements each day. This can be seen in the changes to Geographic Information Systems ...
Predicted ash hazards from potential eruptions at Nevado Sabancaya, Peru: HYSPLIT and remote sensing
(2012)
Nevado Sabancaya (15°47'S, 71°51'W) produced a series of vulcanian eruptions from May 1990 through 1998. Ash from these eruptions falling onto the ice fields of Nevado Hualca Hualca (just north of Sabancaya volcano) melted ...
The Role of Geologic Heterogeneity to Constrain Root Water Uptake
(2017)
Under a future climate, shifting hydrologic conditions may impact the distribution of wetland plant communities, threatening ecological functions such as biogeochemical cycling, flood protection, heat island effects, and ...
Time-Series Analysis for Watershed Scale Predictions of Water Quantity and Quality Export from Agricultural Watersheds
(2011)
Complex hydrological models are widely used to predict overall watershed responses by incorporating knowledge acquired on field or plot scales. However, processes or complexity critical at smaller scales may not necessarily ...
Risk-based characterization of contaminated industrial sites using a multivariate statistical and GIS-based approach in Anniston, Alabama
(2011)
Polychlorinated biphenyls (PCBs) were produced in Anniston, AL, and used in various commercial applications from 1929 until their ban in the mid-1970s due to concerns about their environmental and biological persistence ...
Rill and gully morphodynamics and sediment flux: Implications for drainage network development and landscape evolution
(2011)
Rill and gully erosion, as conditioned by actively migrating headcuts, contributes greatly to overall sediment yield from landscapes in a range of environments worldwide. Accurate prediction of rill and gully development ...
