In order to investigate the influence of igneous rock powder and silica fume on performance cement mortar, facilitate application in engineering, promote greening industry, this study examined pozzolanic activity three different types powders: granite, andesite, tuff. It explored workability mechanical properties both binary systems (igneous rock–cement) ternary rock–silica fume–cement). Microscopic techniques including X-ray diffraction (XRD), thermogravimetric analysis–differential thermal...
Load forecasting plays a crucial role in the power system operation and planning. However, with people's increased awareness of privacy, consumers may not be willing to share their data retailer. Thus, conventional centralized training approach could adopted. To tackle these issues, we propose distributed short-term individual load method based on federated learning framework called FedForecast, which protect privacy make full use edge computing resources. In this framework, models rather...
To address the issues of poor folding quality left and right movable blocks, low efficiency cutting knife counter roller maintenance, abnormal operation clamping device in ZB25 soft box packaging machine, a comprehensive diagnostic analysis was conducted using digital monitoring technology. By optimizing design block guard teeth, quick-change roller, swing rod axis, overall equipment improved to 92.7%, resulting daily production increase 124,000 units an annual economic benefit 1.898 million...
Ultrasonic waves, which constitute an active testing method, and acoustic emissions (AE), can be applied as passive technology, reveal rock damage processes in different ways. However, few studies so far have simultaneously adopted both, owing to the limitations of experimental apparatus. simultaneous use both methods improve efficiency help understand evolution more comprehensively. In this study, concurrent experiments ultrasonic waves AE activities were carried out on salt under uniaxial...
Introduction Retinal diseases significantly impact patients’ quality of life and increase social medical costs. Optical coherence tomography (OCT) offers high-resolution imaging for precise detection monitoring these conditions. While deep learning techniques have been employed to extract features from OCT images classification, convolutional neural networks (CNNs) often fail capture global context due their focus on local receptive fields. Transformer-based methods, the other hand, suffer...
The traditional statistical models for concrete dam deformation do not consider the effective contribution to residual sequence and thus results in low accuracy of prediction monitoring model insufficient behavior. This study proposes a combined deformation, considering correction by frequency division. horizontal displacement dams is driven water pressure, temperature, aging factors. In this study, an accurate value pressure obtained finite element calculation, then hybrid constructed....
The crack propagation process in single-crystal aluminum plate (SCAP) with central cracks under tensile load was simulated by molecular dynamics method. Further, the effects of model size, length, temperature, and strain rate on strength SCAP growth were comprehensively investigated. results showed that, increase rate, plastic yield point occurred advance, limit stress decreased, deformability material increased, but temperature had less effect sensitivity SCAP. size affected deformation...
The mechanisms of deformation at the crack tip in L12 Ni3Al have been studied by molecular dynamics simulations. stress-induced microtwinning is found to occur when a sufficiently high stress concentration exists. formation mechanism discussed. It be achieved emission Shockley partial dislocations from and then slip on adjacent {111} planes. Furthermore, also discussed standpoint stress.
Application of othotropic composite materials makes the engineer to get ultra-light structure with higher load-bearing capability easily. This paper gives optimization algorithm considering both topology and optimal configuration fiber in material. In procedure design mechanical part, high ratio performance-cost, layout (include topology, material shape etc.) properties different direction should be designed simultaneously, thus full can used efficiently. An ideal possess good macroscopic...
The employment situation of graduates can directly reflect the quality talent training and social recognition school.Based on big data analysis method, learning a graduate evaluation model to predict guide students in school.This way not only will improve success rate but also ability universities.This paper collects information from university Beijing past three years.We use Analytic Hierarchy Process establish an model.more importantly, we learn student distribution unsupervised manner,...
This paper analyzes the strain stability during mining, which often causes a water inrush. Mining couses costant stress on fault zone, is loading process system composed of material and surrounding medium. A cusp catastrophe model presented necessary sufficient conditions leading to systems are discussed. The zone assumed be planar combination two media: medium-1 elastic-brittle or strain-hardening medium-2 strain-softening. shear stress-strain constitutive for strain-softening medium...
Pylons of cable-supported bridges are especially important components. They generally large in scale and bear the main loads bridge, involving requirements both structural performance aesthetics. In this paper, a new form finding method for pylon is proposed, with use bi-directional evolutionary optimization (BESO) application aesthetic rules. The principle BESO process discussed. Hangrui Dongting Lake Bridge 3rd Panama Canal used as cases to illustrate proposed method. These two suspension...
