Pd-based materials have received remarkable attention and exhibit excellent H2 sensing performance due to their superior hydrogen storage catalysis behavior. However, the synergistic effects originated from decoration of Pd on a metal oxide support boost are ambiguous, deep investigation interaction (MSI) mechanism is still unclear. Here, model material nanoparticle-decorated WO3 nanosheet synthesized, individual fine structures can be achieved by treating it at different temperatures....
Automatic building extraction based on high-resolution aerial images has important applications in urban planning and environmental management. In recent years advances performance improvements have been achieved through the use of deep learning methods. However, design existing models focuses attention to improve accuracy an overflowing number parameters complex structure design, resulting large computational costs during phase low inference speed. To address these issues, we propose a new,...
Many noise sources that are characterized by an abrupt amplitude increasing give the appearance of genuine microseismic events. This includes human walking, passing vehicles and explosions. Some them cannot be muted bandpass filtering which is commonly applied as pre-processing technique for raw data processing. Due to similarities a unwanted events in their waveforms tend trigger event detection threshold picked common methods such STA/LTA. In this paper, we have demonstrated how use...
In-plane Mo 2 C/MoO 3 heterostructures possess rich grain boundaries which facilitate the generation of coordination unsaturated atoms and thus provide Lewis acid sites for TEA adsorption.
Fracture characterization is essential for estimating the stimulated reservoir volume and guiding subsequent hydraulic fracturing stimulations in shale reservoirs. Laboratory experiments can help provide theoretical technical guidance field operations. In this study, on samples from Niutitang Formation Hunan Province (China) under a uniaxial loading condition are conducted. The multifractal method used to analyze acoustic emission (AE) signals characterize fracture initiation propagation....
Surface based micro-seismic monitoring of well stimulation by hydraulic fracture now has been accepted domestic oil and gas industry.Micro-seismic data can be used to evaluate the result, predict reservoir stress state guide drilling horizontal laterals, etc. microseismic methods corresponding processing technique naming vector scanning micro-fracture successfully mapped fractures.Through analysis spatial temporal distribution energy, process is understood.The current stimulated then...
Surface microseismic monitoring of hydraulic fracturing is now becoming more and popular in the production unconventional hydrocarbons.The frequency analysis surface detected event comparison with perforation downhole recorded may lead to deeper understanding variations events contribute development innovative filtering techniques.In this paper, two by arrays, one geophones are presented.S-transform used derive time representations these events.The contents three types characterized compared...
As the technology has become more and advance massive data been produced pre-processed became useful information to big so come out a lot of like mining, neural network, deep learning, etc. Each its advantages, this paper put forward width depth learning algorithm is advantage two types methods This new method combining Flexible Neural Tree(FNT) Broad Learning System(BLS) network. After several times experiments, we can confirm that hybrid increase accuracy, sensitivity, specificity Heart...
With the rapid development of urbanization, a large number people have poured into cities, which makes traffic congestion problem increasingly serious. As stable, efficient, safe and environmentally friendly public transport, subway has gradually become first choice for residents to travel by bus. The increase in passengers caused great pressure on quality operation service. Therefore, how accurately predict passenger flow station at certain time future let department make corresponding plan...
Microseismic imaging is a common technique for monitoring oilfield completion and production processes. Accurate of the source location microseismic event imperative importance accurate fracture mapping. In this study, we investigate uncertainties in estimated locations events given two different receiver array geometries by applying semblance-weighted stacking method to simple synthetic examples.The error ellipsoid, i.e. extent stack image at 50% maximum, used as relative measure...
In the past three years, some moderate-sized earthquakes (M>4.0) took place in southern Sichuan Basin, China and were suspected to be associated with hydraulic fracturing stimulation for producing shale gas. The objective of this study is investigate relation between an earthquake sequence at two gas well pads results focal mechanism determination stress inversion. We calculated mechanisms observed using a full-waveform matching method. This method not only fits waveforms data, but also...
