Short-term prediction of construction waste transport activities using AI-Truck

no code implementations7 Dec 2023 Meng Xu, Ke Han

Construction waste hauling trucks (or `slag trucks') are among the most commonly seen heavy-duty diesel vehicles in urban streets, which not only produce significant carbon, NO$_{\textbf{x}}$ and PM$_{\textbf{2. 5}}$ emissions but are also a major source of on-road and on-site fugitive dust.

Distribution-Free Pointwise Adjusted P-Values for Functional Hypotheses

1 code implementation1 Dec 2019 Meng Xu, Philip T. Reiss

Whereas such envelope tests examine deviation from a functional null distribution in an omnibus sense, in some applications we wish to do more: to obtain p-values at each point in the function domain, adjusted to control the familywise error rate.
