Condition-based maintenance is critical to reduce the costs of and improve production efficiency. Data-driven method based on neural network (NN) one most used models for mechanical components condition recognition. In this paper, we introduce a new bearing recognition multifeatures extraction deep (DNN). First, calculates time domain, frequency time-frequency domain features represent characteristic vibration signals. Then nonlinear dimension reduction algorithm learning proposed redundancy...
The frequency content of strong ground motions from subduction slab earthquakes differs significantly that produced by other categories (tectonic locations: shallow crustal, upper mantle, and interface) in zones. In the last two decades, a large number records events have been obtained Japan. We present ground‐motion prediction equation (GMPE) for this category earthquakes. used dataset reliably identified up to end 2012. GMPEs were based on set simple geometric attenuation functions, site...
The inversion of ocean currents is a significant challenge and area interest in remote sensing. Spaceborne along-track interferometric synthetic aperture radar (ATI-SAR) has several advantages benefits, including precise observations, extensive swath coverage, high resolution. However, limited number spaceborne (InSAR) systems are operating orbit. Among these, the baseline length generally suboptimal, resulting low accuracy difficulty achieving operational stability. One approaches involves...
To achieve precise detection of target geometric features, Ka/W/sub-terahertz band imaging radar systems with ultra-wide instantaneous bandwidth have been developed. Although dechirp-based receiver architectures allow for low-sampling-rate signal acquisition, they require linearity in chirp signals, often necessitating precompensation nonlinear errors. While most research addresses polynomial-based error correction, periodic errors remain underexplored, despite their potential to obscure...
The zones where tunnels pass through faults are considered to be severely damaged during earthquakes. Site investigation of crossing revealed that there were different types damage patterns after This article proposed a new seismic design concept “guiding” and “yielding.” Two joints, multilevel brittle-flexible joint flexible joint, based on this investigated in study. A series shaking table tests conducted reduced scale tunnel models under two steps the loading process, fault movement...
Ambient ultraviolet radiation (UVB) from solar and artificial light presents serious environmental risks to aquatic ecosystems. The Pacific oyster, Crassostrea gigas, perceives changes in the external environment primarily through its mantle tissue, which contains many nerve fibers tentacles. Changes within mantles can typically illustrate injury of ambient UVB. In this study, a comprehensive analysis phenotypic, behavioral, physiological demonstrated that extreme UVB (10 W/m²) directly...
To evaluate the performance of ball screw, screw degradation assessment technology based on quantum genetic algorithm (QGA) and dynamic fuzzy neural network (DFNN) is studied. The CINCINNATIV5-3000 machining center treated as study object. Two Kistler 8704B100M1 accelerometers a 8765A250M5 three-way accelerometer are installed to monitor trend performance. First, vibration signal features extracted both in time domain frequency domain. Then feature vectors can be obtained by principal...
Mechanical vibration signal denoising has been an import problem for machine damage assessment and health monitoring. Wavelet transfer sparse reconstruction are the powerful practical methods. However, those methods based on fixed basis functions or atoms. In this paper, a novel method is presented. The atoms used to represent signals learned from raw signal. And in order satisfy requirements of real-time processing, online dictionary learning algorithm adopted. Orthogonal matching pursuit...
Abstract Detection of incipient degradation demands extracting sensitive features accurately when signal-to-noise ratio (SNR) is very poor, which appears in most industrial environments. Vibration signals rolling bearings are widely used for bearing fault diagnosis. In this paper, we propose a feature extraction method that combines Blind Source Separation (BSS) and Spectral Kurtosis (SK) to separate independent noise sources. Normal, from vibration tests processed. We studied 16 groups...
The detection of cracks is extremely important for maintenance concrete structures. Deep learning-based segmentation models have achieved high accuracy in crack segmentation. However, mainstream very computational complexity, and therefore cannot be used portable equipment. To address this problem, a knowledge distilling structure designed by us. In structure, large teacher model named TBUNet proposed to transfer student with symmetry ULNet. the TBUNet, stacked transformer modules are...
Carbonaceous mudstone and shale (CMS) slopes are prone to disintegration, instability, other engineering diseases.This calls for a suitable method evaluate the slope stability eliminate hazards.However, traditional monitoring system is slow in alarm response, inaccurate analysis.Based on BeiDou Navigation Satellite System (BDS), this paper designs novel automatic early warning system.In system, limit equilibrium was combined with Slope SR finite-element that satisfies inequality relationship...
As a new deformation monitoring method, Discontinuous Ground-Based Synthetic Aperture Radar (D-GBSAR) has gradually attracted people's attention, and the key problem it faces is how to compensate for repositioning error caused by radar position offset. To address above issue, this paper studies geometric relationship between spatial baseline target, proposes novel compensation method based on trigonometric model least squares parameter estimation. The feasibility of proposed verified...
Carbuncle, a collection of interconnected furuncles with multiple pustular openings, is usually caused by Staphylococcus aureus (S. aureus). In this condition, both skin and subcutaneous tissue the lesion show severe inflammation. It often occurs in immunocompromized patients such as those diabetes, nephritis, malnutrition, heart failure, hypogammaglobulinemia, exfoliative dermatitis, or pemphigus using corticosteroids for long-term. Antibiotics aggressive debridement are primary recommended...
