A Multiagent Energy Management Control System For Commercial & Industrial Applications, Tyler Wayne Price

Theses and Dissertations

Commercial and industrial customers have increasingly adopted fully-automated demand response (auto-DR) as part of their energy management control strategy to mitigate the effects of rising electricity costs. Some of these customers have also contracted with their power provider to permit voluntary curtailment of power consumption to be negotiated by a human operator. Even still, at the customer-side there are needs to maximize cost savings and automate decision making, and at the provider-side there are needs to reduce peaking demand and demand volatility. This thesis describes a centralized multiagent approach that automatically negotiates demand curtailment with a power provider while making …

Modeling Intermittent And Perennial Headwater Stream Origins In North Carolina., Kevin Macleod

Theses and Dissertations

Low-order headwater streams, a link between the upland landscape and larger streams within a watershed, affect watershed hydrology. Yet current widely available maps inadequately depict headwater streams, underestimating channel length or omitting channels entirely. Intermittent and perennial headwater streams each provide unique habitat. Until recently, it has not been possible to accurately delineate these streams or predict channel flow durations without fieldwork. Recent advances in remote sensing may allow more accurate headwater stream mapping.

Methods for mapping intermittent and perennial headwater streams with a GIS-based modeling approach coupled with field verification were adapted, tested, and evaluated. Four models were developed …
