To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...
Vietnam is considered one of the most climate change-vulnerable countries due to its high dependence on agriculture and its coastal location. Increased atmospheric temperatures caused by climate change also significantly threaten one of Vietnam's most important cash crops, robusta coffee (Coffea canephora). Suitable cultivation sites of robusta, which comprises 97%...
Sampling intervals of precipitation geochemistry measurements are often coarser than those required by fine-scale hydrometeorological models. This study presents a statistical method to temporally downscale geochemical tracer signals in precipitation so that they can be used in high-resolution, tracer-enabled applications. In this method, we separated the deterministic component of the...
Prior research has suggested that homework activities that encourage learners to think more conceptually about to-be-learned material can have positive benefits on overall content learning. Can such activities be implemented successfully in online coursework, and does it produce the anticipated benefit? In two sections of an online Psychology course, participants...
The paper describes research on the representation of knowledge. The goal is to develop a formalism which can be used for the testing of hypotheses on the nature of human understanding and as a foundation or artificial intelligence programs. The ideas expressed herein are implemented in a program which converses...
