Assessing Land Deformation And Sea Encroachment In The Nile Delta, Egypt, Esayas Gebremichael

Research and Creative Activities Poster Day

Persistent scatterer interferometric analyses were conducted on a stack of 84 Envisat ASAR scenes spanning 7 years (2004 to 2010) over the entire Nile Delta of Egypt and surroundings to monitor the ongoing spatial and temporal land deformation, identify the factors controlling the deformation, and model the interplay between sea level rise and land subsidence to identify areas and populations threatened by sea encroachment by the end of the 21st century. Findings include: (1) general patterns of subsidence in the northern delta, near-steady (none) subsidence in the southern delta, separated by a previously mapped flexure zone undergoing uplift; (2) high …

High Performance Bayesian Applications In Medical, Economics And Climate Sciences, Ahmed Almulihi

Research and Creative Activities Poster Day

We apply high performance numerical integration to problems in Bayesian statistics. These are applied to data arising in the analysis of problems in such areas as medical statistics (birth weight data, heart transplant data, photocarcinogen data, radio therapy data), climate (global weather, tornado data), and general statistics applications (multivariate logistic distribution, multivariate normal, nonlinear regression). We compute Bayesian moment integrals using the ParInt integration software that runs efficiently on computer clusters. We compare our results to those in the literature and show excellent performance with respect to accuracy and execution time.

Does Research On Evaluation Matter? Findings From A Survey Of American Evaluation Association Members And Prominent Evaluation Theorists And Scholars, Satoshi Ozeki

Research and Creative Activities Poster Day

• Evaluation is a relatively new, practice-based field
• Evaluation scholars lead the field by presenting their theories
• Evaluation theories are not based on empirical evidence
• Empirical investigation is required to establish the field of evaluation
• There were calls for more research on evaluation (RoE)
• The number of studies on RoE has increased in the past decade
• It is unknown whether RoE is important in the evaluation community
