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)
In this paper, median filter algorithm and motion vector compensation algorithm is researched. We design and implement the algorithms on the FPGA board in detail. According to the tests and experiments, we verify the practicability of the algorithms on FPGA and video surveillance system. The algorithms will effectively increase the efficiency of late video(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)
