In order to solve unstability problem of signaling centralized and locking system in mine which uses sensors to Yu-Gi-Oh distinguish and locate locomotives, the paper introduced a method of locomotive location of coal mine underground by use of speed-measured technology by video.The method uses distance-measured technology of binocular stereo visio
Natural populations experience environmental conditions that vary across space and over time.This variation is often correlated between localities depending on the geographical separation between them, and different species can respond to local environmental fluctuations similarly or differently, depending on their adaptation.How this emerging stru
This work was carried out in the Tissue Culture Laboratory, Horticulture Research Institute, Agricultural Research Center, Giza, Egypt during the period from 2015 to 2017, to investigate some factors affecting propagation of the rare ornamental climber Porana paniculata by tissue culture.Results could be briefed in the following: using clorox at 20
Mobile robots based on simultaneous localization and mapping (SLAM) technology can quickly, accurately, and automatically collect spatial data for spatial intelligent perception and environmental map construction.It is the key to achieving intelligent and unmanned coal mines.However, the current multi sensor fusion SLAM method in coal mines suffers
