Accuracy verification of airborne large-footprint lidar data is important for proper data application but is difficult when ground-based laser detectors are not available.Therefore, we developed a novel method for lidar accuracy verification based on the broadened echo pulse caused by signal saturation over water.When an aircraft trajectory crosses

A new concave shaped high refractive index plasmonic sensor with a micro-channel is proposed in this work, which comprises an analyte channel in the core hole.The sensor is elaborately designed to reduce the interference effect from the metal coating.Furthermore, the impact of the proposed structure on the sensitivity is also investigated by engine

This article analyzes the prospect of developing a virtual learning forum to help rural English teachers capacity building.The forum is considered important to provide opportunities for the teachers to communicate, to share ideas and experiences, and to discuss amongst themselves and with teachers in more developed regions as well as with experts.T
