The hardware and software realization of a network video monitoring system was presented. A S3C2410 processor was used as the core of the embedded video server. The embedded video capturing software was developed according to V4L(video for linux) specification. The real time JPEG video stream was then transmitted from the server to the remote PC client through a socket connection. The system showed...
In this paper, we aim to test the feasibility of very high resolution satellite imagery for urban turf quality mapping. Our study site is the urbanized area of Shenyang City where the dominant turfgrass is Poa L., and the satellite imagery is QuickBird. After extracting grass from QuickBird by texture-combined supervised classification method, we analyze the relationship between green grass coverage...
Geographic Information System (GIS) has a strong ability to visualize and spatial analysis, which monitoring, management, environmental simulation of pollution sources needs. In this paper, in support of GIS we design the goal, framework, structure of Shanghai Key Pollution Sources Management Information System (SKPSMIS) and implemented it. During developing SKPSMIS, enterprise GIS products, ArcGIS...
We report nano-detection using a silica microtoroid with a reference interferometer. Single polystyrene nano-beads at a record 12.5nm radius are detected; Influenza-A virion binding events with signal-to-noise ratio exceeding 38:1 are observed.
