Marine sediment is an important channel for methane leakage from the earth interior to atmosphere. The investigation of gas invasion in fine-grained marine sediments great theoretical and practical significance science engineering. To study mechanical mechanisms subjected shallow invasion, a injection test with self-developed experimental apparatus was performed, behavior investigated. results ...

The quasi-Monte Carlo (QMC) method was enhanced to solve the population balance model (PBM) including aggregation and fragmentation processes for simulating temporal evolutions of characteristic sizes floc size distributions (FSDs) cohesive sediments. Ideal cases with analytical solutions were firstly adopted validate this QMC illustrate selected pure aggregation, fragmentation, combined system...

Entity Recognition (ER) is a key component of relation extraction systems and many other natural-language processing applications. Unfortunately, most ER are restricted to produce labels from small set entity classes, e.g., person, organization, location or miscellaneous. In order intelligently understand text extract wide range information, it useful more precisely determine the semantic class...

This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

Current crowd counting algorithms are only concerned about the number of people in an image, which lacks low-level fine-grained information crowd. For many practical applications, total image is not as useful each sub-category. example, knowing waiting inline or browsing can help retail stores; standing/sitting restaurants/cafeterias; violent/non-violent police management. In this article, we p...

A new method to refine the event region in a gridbased WSN is presented. The proposed method determines the fine-grained event region from its coarse-grained version using repeated spatial interpolation. Keywords—Coarse-grained event region, fine-grained event region, inverse distance weighting, spatial interpolation, wireless sensor network,

The Sorkheh deposit in northwestern Iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (SSC) mineralization. It consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish Miocene sandstone and shallow-water) that overlie a thick sequence of red beds (Miocene Upper Red Formation). The host gray be...
