Along with the IoT technology, the importance of indoor positioning is increasing, but the accuracy of the traditional fingerprint positioning algorithm is negatively affected by the complex indoor environment.This issue of low indoor spatial geolocation localization accuracy when the signal is collected away from the present stage occurs due to th
New bacterial strains resistant to high concentration of mercury were obtained and character iz ed focusing on their potential application in bioremediation.The biological material was Ball - Shoes Rubber - Junior isolated from soil contaminated with mercury.The ability to removal of Hg from the liquid medium and the effect of the various pH and me
Climate warming on the Tibetan Plateau has been regarded as an important driving force of regional environmental change.Although several studies have analyzed the shift of warming trends on this plateau within the context of a recent global warming “hiatus” since 1998, their disparate findings have hindered a comprehensive and regional
The stress analysis of micro-arc oxidation (MAO) coated aero Al alloys is the basis to reveal the umbrella mechanism of fatigue deterioration.To clarify effects of the coating defects on fatigue life, a stress calculation model with micropores and residual stress is established based on shear lag model in this study.The effects of porosity, substra
