Abstract The metasurface refractive index sensor has a high degree of tunability and flexibility, providing excellent performance for precision sensing applications. absorber with metallic structure been hindered in further applications due to the inherent Ohmic loss material. In this study, dual nanorod based on semiconductor Si was designed, introducing symmetry-breaking excite ultra-narrow q-BIC resonance peaks Fano line shapes. Both are located near-infrared region, multipole analysis...
Abstract This paper addresses the challenge of real‐time, continuous trajectory planning for autonomous excavation. A hybrid method combining particle swarm optimization (PSO) and reinforcement learning (RL) is proposed. First, three types excavation trajectories are defined different geometric shapes digging area. Then, an based on PSO algorithm established, resulting in optimal trajectories, sensitive parameters, corresponding variation ranges. Second, RL model built, results obtained...
Utilising the asymmetry of micro-nano structure to excite Fano resonance in dielectric metasurfaces presents low loss and high field enhancement factors, has a broad range applications optical sensing. Nevertheless, often leads polarization-sensitive characteristics, significantly reducing quality factor sensitivity metasurface, thereby hindering its further application. In this study, metasurface composed materials is designed be completely insensitive x y polarization. The semicircular...
Infrasound signal classification represents a critical challenge that demands immediate attention. Feature extraction stands as the core concept for enhancing accuracy in infrasound processing. However, existing feature methodologies fail to meet requirements long-distance detection scenarios. To address these limitations, this study proposes novel framework based on spatiotemporal characteristics of signals. The proposed incorporates advanced processing techniques, enhancement algorithms,...
<title>Abstract</title> Artificial intelligence plays a crucial role in enhancing the accuracy of positioning global navigation satellite system (GNSS). Although existing reinforcement learning-based correction methods can effectively reduce errors caused by challenging urban environments, they require substantial amount training data as foundation and suffer significant performance losses when dealing with scenarios involving distribution shifts data. These issues severely restrict...
Human is capable of producing versatile and precise speech owing to the complex neuromuscular systems that control movement facial neck muscle groups. Silent recognition based on surface electromyography (sEMG) has been widely researched, which enables communication in absence an audible acoustic signal. However, differences activities groups under different phoneme pronunciation conditions have not well investigated. The present work aims quantify macroscopic spatial patterns activations at...
The color and fluorescence of supramolecular glass were controlled by the non-covalent approach.
We investigated a diffraction optical waveguide structure with double layer coupling configuration. This layer-coupled modulates light information through wavefront modulation for propagation within the and then reproduces further modulation, thus achieving transmission. Analysis indicates that theoretical maximum field of view can reach 90° × 90°. With an actual set to 53° 53°, entrance pupil size 3.2 mm², eye relief 10 mm, 50 expansion, system's total energy transmission efficiency is 37%,...
Forward extrusion is one of the important processes in bulk metal forming. Friction stress can be estimated from slope load-displacement curve at steady state after maximum load a forward test. In this paper, rod tests are carried out to determine experimentally friction various normal pressures, reductions area, billet heights and lubrications. Tested materials include aluminium alloy, low carbon steel stainless steel. Two lubrication methods applied, conversion coating followed by either...

The mathematical expressions these are verified previous...
The most obvious problem in static and dynamic upsetting is dealing with the effects of friction. In friction, final contact area can be divided into two parts: expanded original immigrated area. this paper, aluminium alloy AA 6082, low-carbon steel W.

Electromyography (EMG) based Human-Computer Interaction (HCI) through wearable devices frequently encounter variability in body postures, which can modify the amplitude and frequency features of surface EMG (sEMG) signals. This often results reduced gesture recognition accuracy. To enhance robustness sEMG-based interfaces, mitigating effects position is essential. In this paper, we proposed a Dynamic Balanced Single-Source Domain Generalization (DBSS-DG) transfer learning framework, only...
