In recent years, there have been frequent disasters and accidents in the underground pipeline system of Chinese cities, posing a continuous threat to safety life property public order urban operations. This article uses statistical data on spatiotemporal distribution major various provinces China 2021. By using Pearson’s correlation coefficient regression analysis, causal analysis model for is ...

The concealment and complex spatial relationships of urban underground pipelines present challenges in managing them. Recently, augmented reality (AR) has been a hot topic around the world, because it can enhance our perception of reality by overlaying information about the environment and its objects onto the real world. Using AR, underground pipelines can be displayed accurately, intuitively,...

The interpolating sequences S for H∞(D), the bounded holomorphic functions in the unit disc D of the complex plane C, were characterized by L. Carleson using metric conditions on S. Alternatively, to characterize interpolating sequences we can use the existence in H∞(D) of an infinity of functions {ρa}a∈S , uniformly bounded in D, the function ρa being 1 at the point a ∈ S and 0 at any b ∈ S \ ...

If coherence is to have justificatory status, as some analytical philosophers think it has, it must be truth-conducive, if perhaps only under certain specific conditions. This paper is a critical discussion of some recent arguments that seek to show that under no reasonable conditions can coherence be truth-conducive. More specifically, it considers Bovens and Hartmann’s and Olsson’s “impossibi...
