Abstract As part of a broader effort to develop ground-motion data resources for China in manner consistent with Next Generation Attenuation projects, we database geotechnical soil profiles and shear-wave velocity (VS) logs sites having accelerometers (this is referred as profile [SPD]), then use that site parameters. The information compiled stations within the National Strong Motion Observation Network System (NSMONS) China. This focused on four provinces western (Yunnan, Sichuan, Gansu,...
Abstract. The 3 August 2014 Ludian, China, Ms = 6.5 earthquake caused many large landslides. biggest occurred at Hongshiyan near the epicenter, had a volume of 1.0 × 107 m3 and dammed Niulanjiang River, creating lake. Post-event field investigations yielded detailed data on following aspects: rock structure landslide, local lithology geometry area around landslide dam composition grain sizes debris avalanche. Based these data, this work analyzes geology topography area, explores reasons for...
This paper introduces a new and unique full-scale testbed site for structural health monitoring soil–structure system identification studies being developed in southwest China. The is 48-story skyscraper with an extended four-level basement, supported by piles, located Kunming, the capital of Yunnan Province. Located diffused zone collision Indian Eurasian tectonic plates, one most active seismic areas mainland final sensor deployment will consist 43 triaxial accelerometers (129 channels)...
Amorphous silicon suboxides (a-SiOy, y < 2) have attracted much attention as promising anode materials for rechargeable energy storage devices. We performed ReaxFF molecular dynamics simulations (ReaxFF MD) to examine the structural evolution, volume expansion, and diffusion properties in amorphous LixSiOy bulks, reveal impact of oxygen content on its performance. Our results suggest that inserted Li atoms preferentially disintegrate Si–Si connections Si-rich oxide (a-SiO0.5), while they...
Abstract. The 3 August 2014 Ludian, China Ms 6.5 earthquake has spawned a mass of severe landslides. Of them the biggest occurred at Hongshiyan near epicenter, which 1200 × 104 m3, clogging Niulanjiang River, and creating large dammed lake. Post-event field investigations yield detailed data on following aspects: rock structure landslides, lithology, geometry dam, composition grain sizes debris avalanches. Based these data, this work further analyzes geology topography area, explores...
The soil-structure interaction (SSI) is an integral part of the seismic response structures. knowledge about its effects based largely on numerical simulations involving simplified models. In this paper, we examine consequence several assumption in SSI models buildings, with emphasis rigid foundation assumption. To end, analyze variants a linear three-dimensional finite element model structure and soil corresponding to uniquely instrumented 50-story skyscraper, basement pile foundation,...
Abstract The temporary strong-motion observation in Yunnan Province, southwestern China, has obtained a valuable batch of near-source recordings from many small earthquakes 2008 to 2018. Based on the 546 well-processed with R = 4–35 km, which were at 56 stations 198 ML=2.0–4.3 we established ground-motion attenuation models for peak ground acceleration and spectral accelerations (PSAs) periods 0.1–2.0 s investigated characteristics motions events. Our model includes source term represented...
A seismic sequence has struck the Yangbi county, west part of Yunnan Province in southwest China since May 18, 2021 . This region experienced strongest ground shakings on night 21 with successive occurrence four earthquakes MS ≥5.0 a short time and more small earthquakes. Large numbers strong-motion recordings obtained (i.e. 5.6 foreshock, 6.4 mainshock, 5.0 5.2 aftershocks) were analyzed detail to characterize source effects, distance decay, etc. The velocity pulse-like waveform at...
Abstract The dense recordings of the 146 accelerometers in near-source area clearly show seismic wave propagation and spatial variability strong ground motions during 2021 Yangbi earthquake Western China. observation demonstrates that are characterized as short duration (< 15-20 s) but large accelerations short-period spectral values. dominant period is generally (0.1-0.5 s); whereas, some records, reaches 1.5 s while affected by soft deep sediments. observed peak velocities (PGVs)...
The S-Transform which is used in many fields, better the methods of time-frequency analysis. Although improves analysis, it also increases algorithm complexity, resulting rapidly increasing computing time and needing more memory. Therefore, difficult to be applied for real-time procession signal. Based on characteristics that human being insensitive voice frequency resolution, this paper, we propose a compressing S-transform. Through re-sampling frequency, decreases data size, computer...
Three-component displacement time histories on the surface of near-field fault are obtained from analytical calculation seismic moment release rate function and energy center source model.Analytical strong motion compared with records in meizoseismal area, results indicated that, during Ludian Ms6.5 earthquake rupture process, NW-SE is main seismogenic even if conjugated NE-SW direction also play role in.This proposed method using functions to determine comprehensively dominant direction,...
Based on the needs of financial regulation, in view features high proportion long entities and rich professional vocabulary information text this field, we proposes model Lexical-Fusion BERT(LF-BERT), which is a named entity recognition (NER) suitable for field. LF-BERT obtains character vectors based BERT, integrates relevant lexical inter-lexical correlation with attention mechanism bidirectional short-term memory network (BiLSTM), adopts head-end label prediction to realize recognition....
Based on the actual demand of conducting banking business compliantly for intelligent retrieval financial-field regulatory documents (FRDs), in view features containing non-pairwise semantic information, high knowledge cohesion within segments and low coupling between FRDs, this paper, hypergraph structure is adopted, a model based HGNN that can effectively classify graphs field constructed to implement graph classification, called Cohesive Hypergraph Convolutional Network (CHCN) model....
Recent robot technology (RT) has made remarkable progress in both manufacturing and service sectors.Because of this RT advanced technology, there are growing demands to make robots work more friendly flexible coordinated with human for service.There many research developing works undergoing interaction, such as assistance supports by manufacturing, inspection maintenance, entertainment, education, bio-medical applications, rehabilitation techno-care aged people.Robot is required have the...
Relation extraction is a natural language processing (NLP) task to extract semantic relations between entities from unstructured texts, and an important research content of constructing knowledge graph. Based on the documents issued by China Banking Insurance Regulatory Commission, we construct graph in field financial regulation through relation extraction, which helps bank staff realize intelligent query regulatory locate business-related requirements quickly accurately. This paper...
With technologies of knowledge graphs, the compliance management banking business based on documents issued by financial regulatory agencies can help relevant personnel realize intelligent queries. During our research, it is found that there are still existing some undiscovered relationships between entities in current KG. Meanwhile, needs bank for KG constantly changing. Besides queries such as keyword retrieval, higher requirements put forward, hoping to obtain more abundant with relevance...
