Non-destructive and accurate estimation of crop biomass is crucial for the quantitative diagnosis of growth status and timely prediction of grain yield.As an active remote sensing technique, terrestrial laser scanning (TLS) has become increasingly available in crop monitoring for its advantages in recording structural properties.Some researchers ha
Impurity removal is a momentous part of zinc hydrometallurgy process.In this paper, a hybrid modeling method of mechanism modeling and parameter estimation modeling was proposed on the basis of not Hanging Decor changing the actual production process of lead-zinc smeltery.Firstly, the overall nonlinear dynamic mechanism model was established, and t
Abstract Alluvial fans are large-scale depositional structures commonly found at the base of mountain ranges.They are relatively soil-rich compared to the rocky terrains, or catchment areas, from which their material originates.When frequented by debris flows (massive, muddy, rocky flows) they contribute significantly to local hazards as Vertex Kit
We generalize the nested Wilson loop formalism, which has been playing an important role in the study of topological quadrupole insulators, to two-dimensional (2D) and 3D nonsymmorphic materials with higher-order topology.In particular, certain 3D Dirac semimetals exhibit 1D higher-order Fermi arc (HOFA) states localizing on hinges where two surfac
