A new strategy to discriminate four types of hazardous gases is proposed in this research. Through modulating the operating temperature and the processing response signal with a pattern recognition algorithm, a gas sensor consisting of a single sensing electrode, i.e., ZnO/In₂O₃ composite, is designed to differentiate NO₂, NH₃, C₃H₆, CO within the level of(More)
Multi-seasonal TM, ETM+ and OLI remote sensing images data of Jaozuo city in 1988, 1993, 2001, 2004, 2010 and 2014 were classified by using Random Forests algorithm. The dynamic of land use/cover was then obtained and related to the main driving factors. The results showed that: (1) DEM was more important than other variables during the process of(More)
Based on summing up forecasting method and theory about water-inrush from floor of working face, combined with a lot of practical information analysis, the main five factors controlling water-inrush from floor are found out, which are water yield property of aquifer, water pressure, effective confining stratum thickness of mining floor, fault or broken zone(More)
When interpolating feature points into constructed triangulated irregular network, it will give rise to reconstruction of the original triangulation. This requires finding out the interpolated point's positions and partial adjustment of triangulation where the points inserted. These operations need a large amount of computing. In this paper, we will discuss(More)
