Enhanced monsoon duration and soil acidification from acid rain are expected to impact the distribution of microbial communities in surface subsurface environments, although these impacts poorly understood for most systems. In central China, soluble carbonate bedrock forms extensive karst landscapes. Current predictions that amount monsoonal precipitation rainfall China will increase, which is lead changes pH balance ecosystems. To evaluate role pH, total organic carbon, other geochemical...
Multi-fractured horizontal well (MFHW) is extensively applied to develop the shale gas reservoirs. After massive fracturing, complex fracture network will exist around wellbore. To model flow behavior more rigorously, fractures within should be represented explicitly rather than idealized as dual-porosity media Thus, a conceptual of discrete for MFHW first constructed by using unstructured perpendicular bisection (PEBI) grid. Then, mathematical considering stress sensitivity reservoir...
Accurately positioning and identifying coal gangue under the heterogeneous complex scenarios of production is a key difficult problem for sorting robot. This paper proposes an image processing based method further develops identification system. The samples are selected from Hancheng Coal Mine, China's Shaanxi province. Three automatic threshold segmentation methods used binarization comparative analysis shows that clustering outperforms others. Particle carried out by using morphological...
Gas field production forecast is an important basis for decision-making in the gas industry. How to accurately predict dynamic during development content of reservoir engineering research. Reservoir numerical simulation most common method predicting oil and production. However, it requires a lot data build accurate geological model which tedious time-consuming. At present, many scholars have used machine learning mining methods production, but they not considered whether use increasing...
Short-term exposure to air pollution has been associated with ischemic stroke (IS) hospitalizations, but the evidence of its effects on IS in low- and middle-income countries is limited inconsistent. We aimed quantitatively estimate association between hospitalizations for Chongqing, China. This time series study included 2,299 inpatients from three hospitals Chongqing January 2015 December 2016. Generalized linear regression models combined a distributed lag nonlinear model (DLNM) were used...
For the remaining useful life (RUL) prediction of rolling bearing under strong background noise, it is hard to get accurate results based on non-stationary vibration signals because complex degradation characteristics and difficult extraction key features. The framework RUL for established by integrating multi-domain mixed features temporal convolutional network (TCN). variational mode decomposition method dung beetle optimization algorithm developed reduce signal noise determining optimal...
The efficient management and utilization of coal mine equipment maintenance knowledge is an indispensable foundation for advancing the establishment intelligent mines. This has problems such as scattered, low sharing, insufficient management, which restricts development intelligence. For above-mentioned problems, a large language model based on multi-source text (XCoalChat) was proposed to better manage utilize existing massive maintenance. dataset ReliableCEMK-Self-Instruction constructed...
Abstract The development of information technology has prompted big data to become an important force for educational progress. purpose this paper is explore the application data-driven in field civic education. Taking education course agricultural and water majors as research object, K-prototype clustering algorithm, mining least squares support vector machine algorithm are applied construction students’ portraits, recommendation resources evaluation teaching effect education, etc....
As an acute ophthalmic infection, bacterial keratitis (BK) can lead to severe visual morbidity, such as corneal perforation, intraocular and permanent opacity, if rapid effective treatments are not available. In addition eradicating pathogenic bacteria, protecting tissue from oxidative damage promoting wound healing by relieving inflammation equally critical for the efficient treatment of BK. Besides, it is very necessary improve bioavailability drugs enhancing ocular surface adhesion...
Many significant breakthroughs have been made in regards to deep oil and gas exploration development recent years. However, a systematic analysis has not carried out on the progress, challenges, trend of onshore resources China. This paper summarizes five main points resources: (1) more gas, less oil, complicated phases; (2) high temperature pressure, as well profoundly different basins or formations; (3) multiple hydrocarbon sources accumulations; (4) relatively tight but effective...
Vehicular ad hoc networks (VANETs) have stimulated interests in both academic and industry settings. Once deployed, they would bring a new driving experience to drivers. However, an open-access environment, privacy is one of the greatest challenges, as drivers want keep their personal information protected. Therefore, many authentication protocols been proposed solutions issue. In most existing protocols, prevent revoked entity from generating valid information, verifiers must frequently...
Currently, the research on health state of rotating machinery under time-varying operating conditions mainly focuses using a combination several constant or uniformly changing speed and load. This article studied status recognition nonlinear continuous changes in A method was proposed based gram angle field deep residual contraction network. Considering influence working signal characteristics, speed, load, multidimensional time-domain features are fused to form feature vectors. The vectors...
During the drilling process, rock mechanics parameters (RMP) are an important basis for optimizing fluid density, drill bit selection, and wellbore stability. However, during actual drilling, traditional methods cannot obtain RMP of arbitrary sections. To solve problem RMP, a novel data-driven method predicting is proposed. Initially, Pearson correlation coefficient used to analyze between data well label obtained by logging. And major influence factors (e.g., pressure, speed) chosen...
