Training Load Monitoring Algorithms on Highly Sub-Metered Home Electricity Consumption Data

The growing interest in energy-efficient buildings is driving changes in investment, design, and occupant behavior. To better focus cost and resource conservation efforts, electricity consumption feedback can be used to provide motivation, guidance, and verification. Disaggregating by end-use helps both consumers and producers to identify targets for conservation. While hardware-based sub-metering is costly and labor-intensive, non-intrusive load monitoring (NILM) is capable of gathering detailed energy-use data with minimal equipment cost and installation time. However, variations in measurements between metering devices complicate the process of compiling the necessary appliance profiles. Future work involves the devel-opment of NILM algorithms using sensor fusion and detailed appliance-level data gathered from a highly-sensed house currently being constructed near Pittsburgh, Pennsylvania.

Carbon isotope negative excursions across the Triassic-Jurassic boundary interval in the Tibetan Himalayas

Fossils from sections at Germig in the Tibetan Himalayas allow the establishment of ammonoid assemblages ranging from uppermost Triassic to basal Jurassic. The carbon isotope profile from these sections shows a majority of positive values in the Rhaetian, and negative values within the Hettangian intervals. Pronounced negative excursions between the Triassic and Jurassic boundary corresponds to the end-Triassic extinction. A stepwise pattern of the end-Triassic extinction is demonstrated by the bivalves and ammonoids. However, the warm episode persisting throughout from late Triassic to basal Hettangian in the Tibetan Himalayas, indicated by subtropic and tropic forms remains to be interpreted.
