“…As a gateway to international trade, the port is a distribution center for material import and export. With the rapid development of modern industrial technology, the degree of port automation and mechanization has gradually increased [9]. However, due to the complex working environment and huge workload of port machinery, the parts of machinery are prone to failure.…”

In order to solve the problem that there is a huge amount of port machinery operating state data, the traditional fault diagnosis method is difficult to effectively obtain the mechanical fault information from the massive data and also cannot accurately diagnose the fault. This paper presents a fault diagnosis method for port machinery based on the FastAP algorithm. By analyzing the characteristics of the FastAP algorithm, the algorithm is introduced into port machinery fault diagnosis, and a port machinery fault diagnosis model based on FastAP is proposed. Through simulation experiments, the algorithm and its application in port machinery fault diagnosis are verified. The experimental results show that compared with the standard AP algorithm, the FastAP algorithm performs well in the sum of similarity, clustering accuracy, and clustering calculation time and has better performance, which is more suitable for fault diagnosis. The fault diagnosis method based on the FastAP algorithm has a high diagnosis accuracy of port machinery fault, reaching more than 92%, and can accurately diagnose the normal state, inner and outer ring fault state, and rolling element fault state of the actual port mechanical belt conveyor. The research on remote control and fault diagnosis of port machinery equipment based on wireless communication technology can effectively solve the problem that there is a huge amount of port machinery operating state data, and the traditional fault diagnosis methods are difficult to effectively obtain mechanical fault information from the massive data and thus cannot accurately diagnose the fault.

“…[ 10 ] Hitherto diversiform soliton pulses can be obtained through different cavity configurations, and their dynamics and applications have been extensively investigated. However, with the rapid development of modern medicine and industry, many applications, including advanced micromachining, [ 11,12 ] imaging, [ 13,14 ] and metrology, [ 15,16 ] increasingly rely on switchable multifunctional soliton fiber lasers, where reproducible and controllable features are particularly required. Limited by the complex dynamics of dispersion, nonlinearity, filtering, polarization, gain, and loss in the lasing cavity, little attention has been paid to the multistate soliton generation from a single oscillator cavity and the practical applications of which need to be further exploited.…”

Modern solitons fiber lasers systems sought for imaging, micromachining, metrology, spectroscopy, and sensing applications, require multifunctional light sources with fully controlled switching features to avail the necessary optical signal. Existing single cavity fiber laser systems have limitations on the generation of multistate solitons due to the intrinsic dispersion, nonlinearity, filtering, gain, and loss. Herein, for the very first time, a compact multifunctional solitons fiber laser controlled by the 3D maneuvering of the polarization beam splitter (PBS) to select the appropriate polarization state for various mode‐locked operations is demonstrated. For single soliton state operation, conventional solitons (CSs), quasi‐coherent noise‐like pulses (QC‐NLPs) and harmonic mode‐locking (HML) are achieved independently, and these different states can be easily and efficiently switched by steering the PBS position. Versatile hybrid dual‐wavelength mode‐locked operations (2‐CSs states, 1‐CS state and 1‐QC‐NLP state, and 2‐QC‐NLPs states) are additional functionalities achievable when the PBS position is steered to suitable positions. The hybrid dual‐wavelength mode‐locked operation has excellent long‐term stability even functioning at maximum output power. It is envisaged that the proposed work provides a compact switchable multifunctional solitons fiber laser system that can be potentially applied in optics signal processing, micromachining, spectroscopy, and optical sensing, etc.

“…After gaining momentum, the electrons collide with dielectric molecules and move towards the workpiece. Depending on the electron's work function and energy, the ionisation of the dielectric molecule may be affected [13]. Collisions between positive ions and electrons result in additional electrons being accelerated.…”

Particle synthesis has seen significant advances in current trends. However, the synthesis of metal particles without oxidation is a challenge for researchers. The current study presents a straightforward, convenient, and convincing approach for manufacturing copper (Cu) particles free of surface oxide. The die-sink Electrical Discharge Machine (EDM) of copper alloys with oleic acid resulted in the formation of Cu particles with diameters between 10 to 20 µm. X-ray diffraction (XRD) was used for particle examination after cleaning and sonication with distilled water. Cu particles with oleic acid coating retained a Cu phase without oxidation after synthesis. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to determine the size and morphology of generated particles. Fourier transforms infrared (FT-IR) analysis revealed the oleic acid-coated Cu surface bonded with an oxygen atom. Also, the agglomeration and change of size involving Cu particles with increasing voltages in the pulse supply in EDM were reported.
