Predicting the remaining useful life (RUL) of rolling bearings is a critical technology for ensuring safe operation and reducing maintenance costs rotating mechanical equipment. The accuracy RUL prediction highly dependent on quality degradation features screened from original statistical features. However, there redundancy between after screening, screening rule subjective. Additionally, some information unselected lost. To solve above problems, this paper proposes feature fusion-based...
Hyperspectral images possess a continuous and analogous spectral nature, enabling the classification of distinctive information by analyzing subtle variations between adjacent spectra. Meanwhile, hyperspectral dataset includes redundant noisy in addition to larger dimensions, which is primary barrier preventing its use for land cover categorization. Despite excellent feature extraction capability exhibited convolutional neural networks, efficacy restricted constrained receptive field...
A Gram-stain-negative, non-spore-forming, motile, aerobic bacterium (strain C21 T ) was isolated from coral and identified using polyphasic identification approach. Global alignment of 16S rRNA gene sequences indicated that strain shares 95.7 % sequence identity to its closest neighbour, Marinibactrum halimedae NBRC 110095 , followed by other type strains with identities lower than 95 %. The average nucleotide amino acid values between M. were 69.6 64.8 %, respectively, indicating may...
Zircon Hf-isotopic mapping can be regarded as a useful tool for evaluating the coupling relationship between lithospheric structure and metallic mineralization. Hence, this method shows important significance mineral prediction. To explore potential, published granite zircon Hf isotope data from Sanjiang Tethyan Orogen were systematically compiled. This study uses Kriging weighted interpolation in Mapgis software system to contour isotopes, revealing relation crustal metallogenesis. The...
Hyperspectral remote sensing technology has been in front of science and technology. It brought a technical revolution for sensing. let the spatial spectral dimensions traditional image information fusion to an organic whole. make multispectral features wide band be detected differentiated hyperspectral detection. mineral mapping is most successful which can exert its advantages application field geology. Using airborne visible-light near infrared short-wave imaging HyMap data, we research...
For the Jiawula lead–zinc deposit, as easily accessible resources become depleted, mines are becoming deeper to replenish ore reserves. Identifying large, continuous, and high-grade bodies in deep areas has a daunting problem. Moreover, separating lead–zinc-bearing complex from waste material extracting them associated minerals also difficult. Thus, pioneering exploratory strategies technological methodologies required make breakthroughs mineral discovery. Based on extensive-scale structural...
In this study, in order to obtain excellent mechanical properties TiB2/Al–Cu–Mn–Cd composite, an optimized heat treatment, i.e., short-time solution treatment at 535 °C for 1 h following long-time 523 11 h, and aging aged 170 12 is proposed. addition, study investigated the connection between microstructure evolution during treatment. The results show that with adoption of area fraction second eutectic Al2Cu phases decreased from 5.08% as-cast state less than 0.36% owing improvement...
The giant Yulong porphyry Cu (‐Mo‐Au) deposit was formed in a post‐collisional setting eastern Tibet, which is associated with Eocene potassic to ultrapotassic felsic intrusive rocks. origin of the intrusion remains highly disputed. Hence, we present new zircon U–Pb ages, whole‐rock geochemistry and Lu‐Hf isotopes for intrusion. Zircon dating from porphyritic monzogranite quartz monzonite yield ages 41.1 ± 0.2, 40.8 0.1 40.5 0.2 Ma, respectively. Samples exhibit high K 2 O (4.13–4.85%), O/Na...
The remaining useful life (RUL) prediction of rolling bearings can avoid unreasonable maintenance and major safety accidents. Considering the non-stationary characteristics, it is difficult to utilize deep learning-based method directly extract degradation features from bearing vibration signal. Therefore, in this paper, a fusion model AE-BiLSTM proposed. AutoEncoder (AE) used frequency-domain signals, BiLSTM network predict RUL. experimental verification conducted on FEMTO-ST dataset....
Pollution takes many different forms from the atmosphere to oceans pollution is everywhere and a global problem. Natural mainly divided into air pollution, water land pollution. Air caused by small particles emitted large amounts of energy. Water human-made waste its impending set consequences. Land human activities, especially use management materials. These three types are interrelated, cause one type may become result another. This paper discusses main sources in atmosphere, land,...
