Improving The Performance Of Ice Sheet Modeling Through Embedded Simulation, Christopher G. Dufour
Improving The Performance Of Ice Sheet Modeling Through Embedded Simulation, Christopher G. Dufour
Electronic Theses and Dissertations
Understanding the impact of global climate change is a critical concern for society at large. One important piece of the climate puzzle is how large-scale ice sheets, such as those covering Greenland and Antarctica, respond to a warming climate. Given such ice sheets are under constant change, developing models that can accurately capture their dynamics represents a significant challenge to researchers. The problem, however, is properly capturing the dynamics of an ice sheet model requires a high model resolution and simulating these models is intractable even for state-of-the-art supercomputers.
This thesis presents a revolutionary approach to accurately capture ice sheet …

Evaluation Of Multi-Level Cognitive Maps For Supporting Between-Floor Spatial Behavior In Complex Indoor Environments, Hengshan Li
Electronic Theses and Dissertations
People often become disoriented when navigating in complex, multi-level buildings. To efficiently find destinations located on different floors, navigators must refer to a globally coherent mental representation of the multi-level environment, which is termed a multi-level cognitive map. However, there is a surprising dearth of research into underlying theories of why integrating multi-level spatial knowledge into a multi-level cognitive map is so challenging and error-prone for humans. This overarching problem is the core motivation of this dissertation.
We address this vexing problem in a two-pronged approach combining study of both basic and applied research questions. Of theoretical interest, we investigate …
