As an important facility to ensure the safety of water supply, regulating pond a raw pumping station in Tianjin Section middle route South-to-North Water Transfer Project linked from Hanjiang River with urban plants. Surface sediment samples different regions regulator were collected summer, autumn, and winter 2022 spring 2023, respectively. Metagenomic sequencing technology was used analyze distribution characteristics influencing factors antibiotic resistance genes （ARGs）, correlation...
High accuracy in the simulation of discrete-element method (DEM) depends on proper selection microparameters. In this study, range microparameters was determined through sensitivity analysis. Subsequently, four levels orthogonal experimental tables were established and 148 sets data collected. addition, five mining methods, namely, support vector regression (SVR), nearest-neighbor (NNR), Bayesian ridge (BRR), random forest (RFR), gradient tree boosting (GTBR), used to establish a...
Based on the Markov model and basic theory of information entropy, this paper puts forward a new method for optimizing location observation points in order to obtain more from limited geological investigation. According existing data data, classification tunnel lithology was performed, various distribution were determined along using theory. On basis entropy theory, obtained axis tunnel. Therefore, different could be acquired by calculating rocks. Furthermore, uncertainty increases when...
Accurate anomaly detection of gateway electrical energy metering device is important for maintenance and operations in the power systems. Traditionally, was typically performed manually through analysis collected information. However, manual process time-consuming labor-intensive. In this condition, paper proposes a hybrid deep-learning model, which integrates Stacked Autoencoder (SAE) Long Short-Term Memory (LSTM), intelligently detecting abnormal events device. The proposed model named...
Disc cutters are the dominant tool used in excavation of hard rock formations any underground construction application, such as when tunneling using tunnel-boring machines (TBM), well shaft- and raise boring operations. Optimization cutting geometry a given disc cutter for application formation often involves full-scale tests, which is difficult costly proposition. An alternative to testing numerical simulation TBM optimization under different settings. Recent efforts field simulations have...
We used the hyperbolic Drucker–Prager and damage-failure models to simulate a three-dimensional rock fragmentation with tunnel boring machine (TBM) disc cutter through ABAQUS. The energy entropy method was proposed identify optimal spacing. In order verify results of numerical simulation, previous linear cutting (LCM) test data were referred to. simulation verified by comparing mean rolling force specific against corresponding values from LCM tests. showed good agreement results, thus...
The situation in the 1990’s before implementation of integrated water allocation Yellow River and after between 1999 2008 are compared, a combination qualitative quantitative analysis is adopted to assess social effects ten year’s River. agricultural surface consumption regulation averagely decreased 17.7*108m3, eco-environmental lower reaches during non-flood season increased 14.6*108m3,which curbed decreasing trend ecological use for channel from 1970s to1990s.The results show that has...
Large-scale water resource system with multi-water resources and multi-users consists of several independent supply drainage network systems. It is hard to solve the problem well large-scale traditional planning method. We model optimal allocation using principles biological evolution, eliminate inferior by judging optimization degree each generation individuals, then produce a new generation, thus accomplished through iteration repeated. The disadvantage that MOGA solution out quasi-global...
Closed-loop control mechanism can lead to auto-correlations of process variables, partial compensation faults and fault propagation effect inside the loop, which make detection closed-loop a difficult task. In this paper, scheme named DiPCA-MDA is proposed deal with dynamics feedback on for sensor process. Dynamic inner Principal Component Analysis (DiPCA) extract dynamic latent variables model their behaviours, two static residuals are generated further monitoring. Discriminant analysis...
