Recent researches have indicated the viability of path-based algorithms for traffic assignment problem and much attention has been received by gradient projection (GP) algorithm. However, the GP algorithm experiences problems near optimal point when trying to obtain high accurate results. To improve its performance near optimal point, this study employs(More)
Suberin-derived substituted fatty acids have been shown to be potential biomarkers for plant-derived carbon (C) in soils across ecosystems. Analyzing root derived suberin compounds bound in soil could help to understand the root input into a soil organic carbon pool. In this study, bound lipids were extracted and identified in root and topsoil samples.(More)
This dissertation proposes an integrated control framework to deal with traffic congestion at freeway interchanges. In the neighborhood of freeway interchanges, there are six potential problems that could cause severe congestion, namely lane-blockage, link-blockage, green time starvation, on-ramp queue spillback to the upstream arterial, off-ramp queue(More)
