Research on the efficiency improvement of pump as turbine (PAT) is inadequate. Blade thickness an important geometry parameter in blade design. To explore effects influence PAT, numerical research three different specific speeds PATs with was carried out. Their performance changes were presented. Besides, variations hydraulic loss distribution increasing performed. Theoretical analysis gives a reasonable explanation for change. Results show thatPAT's flow versus curve ( Q-η) lowered; head...
A gear transmission system is a complex nonstationary and nonlinear time-varying coupling system. When faults occur on system, it difficult to extract the fault feature. In this paper, novel diagnosis method based ensemble empirical mode decomposition (EEMD) Deep Briefs Network (DBN) proposed treat vibration signals measured from gearbox. The original data decomposed into set of intrinsic functions (IMFs) using EEMD, then main IMFs were chosen for reconstructed signal suppress abnormal...
Coal mining-induced surface subsidence can significantly impact resident safety and hinder regional sustainable development, making precise monitoring prediction critical. Existing mining technologies often exhibit low spatiotemporal resolution, while models suffer from heavy dependence on data quality model assumptions, as well imprecise parameters. This study addresses these limitations by proposing a novel method based Small Baseline Subset Interferometric Synthetic Aperture Radar...
Public health emergency management has been one of the main challenges social sustainable development since beginning 21st century. Research on public is becoming a common focus scholars. In recent years, literature associated with grown rapidly, but few studies have used bibliometric analysis and visualization approach to conduct deep mining explore characteristics research field. To better understand present status research, knowledge base hotspots, method science mapping technology were...
Accurate localization of objects interest in remote sensing images (RSIs) is great significance for object identification, resource management, decision-making and disaster relief response. However, many difficulties, like complex backgrounds, dense target quantities, large-scale variations, small-scale objects, which make the detection accuracy unsatisfactory. To improve accuracy, we propose an Adaptive Adjacent Context Negotiation Network (A 2 CN-Net). Firstly, composite fast Fourier...
This paper employs three neural networks that are BP, RBF and PNN for rolling bearing fault diagnosis compares their performance. The preprocessed vibration signals of provide fused feature vectors after the process wavelet package decomposition fusion. Then f used serve as inputs networks. diagnostic aims to recognize health condition, types severity bearings. simulation results demonstrate BP has best accuracy very complex computation efforts, fastest classification with lowest precision....
Gait as a biometric that can be collected at long distance. This feature has many potential applications in monitoring fields. In this paper, the gait representation method of optical flow history image (GFHI) is proposed by combining gray and image, which realizes overall compact localized human motion. We recognition based on combined hidden Markov model (HMM), using two groups models to distinguish similar sequences. The experimental results show paper high accuracy. small dataset,...
The ship route planning has two problems to solve. first problem is how model the environment of navigation area, and second one use an optimal algorithm search global route. This paper combines particle swarm optimization (PSO) with tangent graph method At first, it uses obtain static obstacle information establishes area. It designs a cost function evaluating total distance from start point terminal point. PSO takes minimum value as its target shortest Based on model, individuals are...
In order to enhance weak signals in strong noise background, a signal enhancement method based on EMDNN (neural network-assisted empirical mode decomposition) is proposed. This combines CEEMD (complementary ensemble decomposition), GAN (generative adversarial networks) and LSTM (long short-term memory), it enhances the efficiency of selecting effective natural components decomposition, thus SNR (signal-noise ratio) improved. It can also reconstruct signals. The experimental results show that...
On the basis of using CFRP (Carbon Fiber Reinforced Polymer) to reinforce steel materials and structures, this paper focused on reinforcement method box girder structure. Firstly, FEM models were set up discuss method, stress distribution between overall strengthening flange locally strengthening. Secondly, typical crack model was raised mechanics characteristic, effects under different methods analyzed. The results showed that certain fatigue areas could improve concentration phenomenon SIF...
For higher-level requirements of urban planning and management the recent development "digital earth" city", it is urgent to establish protocols for construction three-dimensional digital city models.However, some problems still exist in technology model, such as insufficient precision not optimizing scene considering constraints building codes.In view those points, a method interactively simulate virtual based on codes proposed this paper.Firstly, constraint functions are set up restrict...
In recent years, the combustion furnace has been widely applied in many different fields of industrial technology, and accurate detection states can effectively help operators adjust strategies to improve utilization ensure safe operation. However, inside change according production needs, which further challenges optimal set model parameters. To segment flame pixels, a novel segmentation method for using adaptive color hybrid‐coded human learning optimization (AHcHLO) is proposed. A new...
Due to the complicated structure, vibration signal of rotating machinery is multicomponent with nonstationary and nonlinear features, so it difficult diagnose faults effectively. Therefore, effective extraction characteristics key machinery. Mode mixing illusive components existed in some conventional methods, such as EMD EEMD, which leads misdiagnosis extracting signals. Given these reasons, a new fault diagnosis method, namely, variation mode decomposition (VMD), was proposed this paper....
