Based on the vapor-solid mechanism, a seeded growth method was developed for the growth of tungsten oxide (WO3) nanowires. In this approach, beside the tungsten source heat at high temperature, additional tungsten seed particles were dispersed on the substrate to promote the growth of nanowires. The surface oxidation of the tungsten seed particles induced the local growth of nanowire seeds, which...
With the growing demands for automotive auxiliary functions, more and more complex applications have been developed based on OSEK/VDX OS. However, how to check the developed applications is becoming a challenge for developers. Although some invaluable formal methods have been proposed to check actual software, these methods cannot be directly employed to check OSEK/VDX applications. In this paper,...
Soil fertility is an extremely important indicator in measuring crop growth and largely affects the crop production potentiality. By comparing the traditional fertility assessment model and the GIS assisted fertility assessment model, we conclude that the GIS assisted method based on geostatistics and GIS technology is very effective in the assessment of soil fertility and widely used to evaluate...
Agricultural land quality monitoring is a fundamental and key work for national food security and cultivated land protection that ensures the sustainable development of agriculture. Traditional land surveys usually take long term and huge effort to conduct, while RS technologies are mainly used to monitor the quantity change of land resources. The changing information of the Natural Quality Index...
Temperature-Vegetation Dryness Index (TVDI) is the most important index in describing the soil moisture. Available TVDI calculation depends on the remote sensing data and computational algorithms. With a partial updating of the algorithms and remote sensing data, it needs to recompile and redeploy the implementation of the TVDI calculation, which contains duplicated work and can't take full use of...
Currently OGC GML (Geography Markup Language) specification has been the in fact standard of GIS data sharing and exchanging, and spatial interoperation. Adopting nested association expression approach of XML data, GML data documents store both spatial information and semantic relationship information of geographical elements. In order to improve the efficient of path query on GML two type information,...
At present, GML data compression is a hotspot in the fields of geographic information sharing, interoperability. Based on the analysis of characteristics of traditional GML data compression methods, the paper proposed a GML compressor with holistic isomorphic characteristics, which achieves semantic isomorphic compression by constructing index encodings of feature elementspsila tags and achieves spatial...
