A growing number of Internet-connected sensors have already promoted the advance sensor search service. Accessing all available objects to find sought results in huge communication overhead, thus a low-overhead and high-precision prediction model (LHPM) is proposed improve efficiency. We design approximation method lower reporting energy cost. Then multistep accurately estimate state. Furthermore, ranking presented assess matching probabilities sensors, so as effectively reduce overhead...
In this study, three types of shape memory fabrics (SMFs) were fabricated by weaving filaments from the weft direction at intervals 2, 3 and 4 cm. Accordingly, four-layered smart fabric systems (SFSs) developed incorporating a SMF layer into traditional thermal protective fabrics. Effects filament interval, position moisture content SMFs on protection investigated. Additionally, insulation evaporative resistance SFSs examined.

Abstract Wheelset bearings are a core component of high-speed trains, and their fault diagnosis is the key to smooth operation. Deep learning widely used in due its powerful classification ability. To explicitly fit features vibration signals further explore relationship between signals, graph attention network (GAT) becoming focus research. Unlike traditional neural networks, GATs can on edges with stronger correlations vertices, making model more when fitting samples non-Euclidean space....
Abstract Developing fabrics with enhanced thermal protection is a cutting-edge topic in area of protective clothing (TPC) for workers under heat hazards.

Nine composite (CFs) using SMA filaments and aramid yarns, different filament interval, air gap orientation, yarn type fabric density, fabricated incorporated...
The time-frequency energy distribution processed by a short-time Fourier transform can be compressed to the real instantaneous frequency synchrosqueezing transformation (SST), which improves concentration of signal.

First, theoretical derivation FRSST algorithm as processing technique given and steps IF are...
Wheelset bearings fault samples of high-speed trains often suffer from insufficient numbers and missing points. However, working conditions are one the most important factors affecting data augmentation repair, which is not sufficiently emphasized by existing methods. Also, generative adversarial networks (GANs) as effective sample generation methods still have many problems, such model collapse training difficulties. To solve these a repair method for train wheelset bearing diagnosis with...
Research into rolling bearing fault diagnosis methods is of great significance because bearings are a key part mechanical equipment. The effect iterative generalized demodulation (IGD) on the fundamental frequency component obvious in at variable speeds. However, there problem; curve octave overlaps, and multiple determinations bandpass filter parameters produce an artificial error that leads to misdiagnosis faults. Therefore, method for based adaptive (AGD) proposed. First, resonance band...
Most fault diagnosis methods require that the source and target machines' classes should overlap number of samples be comparable. However, such assumptions are unrealistic in wheelset-bearing diagnosis. The high reliability wheelset bearings difficulty collecting signals make datasets insufficient. obtained by laboratories can rich samples, types faults, working conditions, which contain a wealth information. Therefore, graph attention-based multichannel transfer learning network (GAMTLN) is...
Time-frequency analysis can effectively reveal the fault characteristics of rolling bearings under variable speed conditions. However, traditional time-frequency method cannot meet requirements anti-noise ability and concentration. The synchroextracting transform (SET) as a novel makes up for these defects, so envelope demodulation based on SET diagnosis is proposed. Firstly, best resonant band selected by adaptive band-pass filter fast spectral kurtosis. Then, amplitude filtered signal...
In this paper, a new line matching approach for high-resolution array remote sensing images is presented.
