A pre-selection space time model was proposed to estimate the traffic condition at poor-data-detector,especially non-detector locations. The space time model is
The silica fiber reinforced silica and boron nitride-based composites (SiO2t/SiO2-BN) were prepared firstly via the sol-gel method and then the urea route,and t
Nanoporous copper with nano-scale pore size was synthesized by dealloying Mn-Cu precursor alloy using a free corrosion method.The effects of heat treatment of M
Pure ZnO and Zn0.96Na0.04O films were grown on quartz substrates by sol-gel technology.The XRD analysis revealed that all thin films had hexagonal wurtzite stru
