Multi-band, multi-service and multi-modulation are new trends of GNSS development. Since novel modulation types like BOC/MBOC and multiplex techniques like (POCET, Interplex) of navigation signals have been utilized [1], the composite navigation performance is indeed improved. However, new challenges have arisen in the navigation signal quality monitoring area. Generally, common standard instruments,...
Sensitivity of soil erosion is the representative of the possibility of occurring soil erosion under natural conditions. Sensitivity evaluation of soil erosion is the reliable method to identify the highly sensitivity areas and evaluate the sensitivity degree in a particular area. This paper uses the revised universal soil loss equation (RUSLE) and GIS technique which has powerful space analysis functions...
Internet and web services contribute to the future of healthcare delivery due to the wide deployment of IP networks around the world. Meanwhile, sensor network as an emerging technology for delivering health information has been attracting more and more attentions recently. As most of existing sensor networks have not been deployed with IP protocol, complex multi-protocol gateways are needed to connect...
