Batch process can exhibit significantly different characteristics across different phases, hence it is significant to partition it reasonably and set up corresponding subphase models for online monitoring. Unlike traditional phase-partition algorithms that customarily exploit the result of PCA algorithm for advanced research, an innovative algorithm which directly extracts effective information from...
Mosaic is a low-cost sensing system for city scale air quality monitoring. Mosaic is able to monitor city scale air quality with low costs by deploying customized sensors on moving vehicles. Objectives of this demo are to show how our customized low-cost sensors work and present the three-layer air quality monitoring system. Details about the node design can be found in [1] which will be presented...
Based on multi-temporal remote sensing data and spatial analysis of GIS, this paper analyzes the characteristics of the ecological destruction and recovery in the seriously damaged areas of Wenchuan Earthquake. By employing the TM, MODIS NDVI multi-temporal data, it analyzes the changes in vegetation and using the Vegetation recovery rate to evaluate the recovery characteristics. The result shows...
