Abstract Current methods for bearing fault diagnosis often fall short in addressing data privacy concerns and typically rely on one-to-one transfer strategies, which are inadequate achieving knowledge distributed environments. To address this issue, a method rolling bearings based federated learning is proposed. This ensures while integrating from multiple domains, thereby enabling more efficient transfer. Specifically, domain adversarial neural network (DANN) introduced as the base model...

The automatic detection and recognition of traffic signs have practical importance for intelligent system. A method some prohibition designed drivers is proposed in this paper. color information HSI space the symmetry property circles are used to detect signs, Histograms Oriented Gradients feature nearest distance recognize them. algorithms tested on datasets we collected real environment, experimental results demonstrate their satisfying performance.

Abstract The objective of this study was to investigate how a stress wave travels in standing tree as it is introduced into the trunk through mechanical impact. A series time-of-flight (TOF) data were obtained from three freshly-cut red pine ( Pinus resinosa Ait.) logs by means two-probe timer. Two-dimensional (2D) and three-dimensional (3D) contour maps constructed based on experimental using commercial software. These represent fronts time sequence, illustrating flow energy within log....

Scene matching has found important and wide applications in imaging guidance of cruise missile. A scene algorithm based on SURF feature is proposed this paper. Firstly, points are extracted respectively from base image real-time image. Then, a coarse-to-fine method used to realize the match points. The been tested collected set. experimental results shows that, compared with frequently-used normal cross-correlation method, can process more complicated geometric deformations existed between...

To examine the comparative effects of different frequencies electrical stimulation (ES) on angiogenesis and gene expression, New Zealand white rabbits with femoral artery ligation in one hindlimb electrode implantation sciatic nerve same were randomly assigned to 4 groups: control group, 1 Hz 10 40 group. The ES procedure involved 5 min stimulation, followed by rest, repeated 8 times daily for consecutive weeks. resting blood flow (RBF) was measured via microspheres technique....

Abstract In order to handle the non-linear system and complex disturbance in marine engines, a finite-time convergence active rejection control (ADRC) technique is developed for of engine speed. First, model relationship between speed fuel injection established on basis mean value model. Then, deal with load disturbances parameter perturbation diesel engine, this paper designs an ADRC approach achieve stability. Finally, simulation experiments show that proposed method has better effect...

The development of rural low-carbon logistics industry has become the main factor affecting rapid China's economy. From perspective low carbon economy, based on analysis level logistics, this paper uses theory and method spatial measurement to analyze interactive effect economic construction in 31 provinces China from 2002 2019, then analyzes mechanism different factors development. results show that: first, have an obvious geographical agglomeration trend. distribution characteristics...

In view of that the current security system cannot quickly respond to remote warning, a remonitoring based on STM32 and GSM/GPRS technology was developed. The alarm signal is sent mailbox or user's mobile phone. actual application results show stable, fast response, high in performance may be widely used family enterprise.

We provide a detailed analytical expression of group-delay dispersion (GDD) and third-order (TOD) for reflection grism-pair compressor without the first-order approximation grating diffraction. The expressions can be used to design compensating dispersive material ray tracing. Furthermore, performance grism pair compressor, depending on parameters, is comprehensively analyzed. Results are shown that we adjust several parameters obtain certain GDD TOD, such as incidence angle beam, refractive...

Photovoltaic power is widely favoured because of its safety, short construction period and other advantages. However, the randomness photovoltaic makes it different from traditional generation so that it's necessary to be considered in safety analysis grid. In this paper, considering power, line overload risk index node low voltage are established by combining theory with K (N - 1 + 1) principle for distribution network which developed (N-1) deterministic principle. IEEE three-feeder...
