A hyperspectral detection model for permeability coefficient of debris flow fine-grained sediments, Southwestern China
نویسندگان
چکیده
Fine-grained sediments are Quaternary with grain sizes of not more than 2 mm. They start first when meeting water, their stability is related to the initial water volume triggering debris flow, and thus plays an important role in flow hazards early warning. The permeability coefficient inter-controlled factor fine-grained sediment stability. However, there no hyperspectral model for detecting large areas, which seriously affects progress Therefore, it great significance establish a detection sediments. Taking Beichuan County, Southwestern China as case, was established. results show that eight bands sensitive correlation (R) 0.6343. T-test on shows P-values all less 0.05, indicating established has good prediction ability precision 85.83%. These also indicate spectral characteristics coefficient. provides scientific basis areas lays theoretical foundation hazards’

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A Model for Fine-Grained Data Citation
An increasing amount of information is being collected in structured, evolving, curated databases, driving the question of how information extracted from such datasets via queries should be cited. Unlike traditional research products, such books and journals, which have a fixed granularity, data citation is a challenge because the granularity varies. Different portions of the database, with var...

متن کاملA Model for Fine-Grained Alignment of Multilingual Texts
While alignment of texts on the sentential level is often seen as being too coarse, and word alignment as being too fine-grained, bior multilingual texts which are aligned on a level inbetween are a useful resource for many purposes. Starting from a number of examples of non-literal translations, which tend to make alignment difficult, we describe an alignment model which copes with these cases...
