Abstract Manipulating the thermal emission in infrared (IR) range significantly impacts both fundamental scientific research and various technological applications, including IR camouflage, information encryption, radiative cooling. While prior has put forth numerous materials structures for these objectives, significant challenge lies attaining spatially resolved dynamically multilevel control over their emissions. In this study, a one-step ultrafast laser writing technique is...
Abstract The signal characteristics are extracted directly from the convolutional level when Convolutional Neural Network (CNN) is used as a fault diagnosis method in most instances. Some scholars have proposed to use Markov Transition Field (MTF) extract before convolution. However, for time-domain signals, extraction difficult, and training process of neural network parameters slow. Therefore, this paper, based on Fast Fourier Transform (FFT) MTF algorithm, (FMTF) frequency domain...
Phased array ultrasonic testing (PAUT) is one of the most advanced inspection methods, providing data in image sequences with increased resolution and coverage, consequently enhancing efficiency. Due to inherently abstract nature ultrasound images, analysis PAUT weld continues rely on expertise experienced inspectors, particularly context shipbuilding welds, which exhibit characteristics such as arbitrary lengths, varying thicknesses, various when associated hybrid laser-arc welding...
We present theoretical and experimentally study on performance of typical FEC codes in wireless ultraviolet communication system. The results show that, the distance increases about 116% with LDPC 41% RS code by comparison that without FEC.
Skid-steering vehicle has strong maneuverability. There are a variety of skid-steering wheeled designed for military or civilian at home and abroad. In this paper, based on the need dynamic control, hierarchical controller is 6×6 vehicle. The speed steering controlled through driving torque motor to following desired yaw rate. Contrary common approaches by designing two-tier control strategy, reference wheel generator used calculate follower reach target speed. To perform small radius...
This paper presents the results of investigations recently done by our research group that improve properties stability GMI sensors exploring giant magneto-impedance (GMI) and GMI-hysteresis Co 67 Fe 4.5 Cu1Si 12.5 B 15 amorphous thin strips, which was most promising soft magnetic material could be used in weak transducers.The strips were prepared so-called planar flow casting technology.With circumferential driving mode, changes on frequency ac current under different external field...
The magnetic loss characteristics of ultra-thin nanocrystalline alloy Fe 73.4 Cu 0.6 Nb 3.5 Si 13.5 B 9.0 with 14μm were studied, and compared conventional strip the thickness 26μm.It was found that reducing could significantly reduce (P) alloys.The frequency (P f ) soft has shown a typical fractal structure, namely, P = O Df .The had significant impact on variation dimension D , parameter Po, its work induction m .
Abstract In recent years, there has been increasing use of thin-walled structures with a plate thickness 6–10 mm in the construction cruise ships. As one important processes ship construction, hybrid laser-arc welding, combining advantages laser welding and arc is increasingly applied ships objective reducing panel deformation. However, due to weak stiffness structure continuous weld length 4–16 m, complex deformation, e.g., buckling will be prone occur. This paper analyzed deformation...
Abstract Hard turning is extensively used in the machining of bearings. The process has a significant influence on properties machined surface. In this paper, multi-pass experiments were AISI 52100 bearing steel, and corresponding simulation model was established. effects multiple pass micro hardness residual stress investigated. results demonstrate that surface single, double triple 30.0%, 25.2% 24.5% higher than initial surface, respectively, at depth 0.1mm speed 100m/min.
