The wireless sensor network (WSN) is a multi-hop that comprises multiple nodes arranged in self-organized manner. It usually deployed unattended areas where can easily be infiltrated by attackers who affect the detection results injecting false data. This paper proposes malicious-node identification method based on correlation theory prevents fault data injection attacks. First, anomalies among similar types of are detected time correlation. Second, malicious identified spatial Third,...
The increasing demand for achieving high-efficiency and high-quality medium-thick aluminium alloy welded structures, especially large scale aerospace components, presents an urgent challenge to the conventional TIG arc welding process. This work proposed a novel double-pulsed variable polarity tungsten inert gas (DP-VPTIG) arc, in which square wave current was simultaneously modulated into ultrasonic frequency (20–80 kHz) low (0.5–10 Hz) pulses. Full penetration welds of 6 mm thick AA2219...
Abstract Owing to the development of industrial production, hidden danger in control systems (ICSs) has considerably increased, causing challenges traditional safety defense methods. The combination machine-learning or deep-learning algorithms and intrusion detection (IDSs) become mainstream method for solving this problem. However, these methods depend on a massive amount high-quality attack traffic data, which cannot be obtained easily owing independence unique characteristics ICSs. In...
Abstract In the last decade, wire + arc additive manufacturing (WAAM), which is one of most promising metal technologies, has been attracting high interest from both academia and industry. WAAM systems are increasingly employed in industry academia, but there still several challenges barriers to process stability control. The highly dependent on how molten feed added into melt pool, known as droplet transfer mode. To ensure a stable deposition process, it essential maintain mode suitable...
The influence of filler wire configuration, such as size and geometry, on the deposition rate (DR) bead formation, has been studied in arc-based directed energy (WADED), but fundamental physics underlying its effect melting melt pool dynamics remains unclear. In this paper, a series plasma DED (plasma-DED) experiments were conducted to investigate impact five different configurations DR dimensions. coupling behaviours melting, metal transfer under also simulated numerically using authors'...
This study investigated the changes in microstructure and mechanical properties of gas tungsten arc welded 7075 aluminum alloy joints using ER5356 ER7150 filler wire subjected to post-weld heat treatment. The property evolution welds was analyzed by both thermodynamics calculations experimental methods. After welding, alloying elements segregated inter-dendritic regions, resulting formation excessive intermetallic compounds. Within with material, region primarily composed T-AlCuMgZn phase....
We present a hybrid brain-machine interface (BMI) that integrates steady-state visually evoked potential (SSVEP)-based EEG and facial EMG to improve multimodal control mitigate fatigue in assistive applications. Traditional BMIs relying solely on or suffer from inherent limitations; EEG-based requires sustained visual focus, leading cognitive fatigue, while EMG-based induces muscular over time. Our system dynamically alternates between inputs, using detect SSVEP signals at 9.75 Hz 14.25...
Aluminum alloy 7075 (with 7055 and 7150 filler wires) was welded using a digital welding machine that can switch arc mode between MIG, CMT CMT+P modes. The transverse-motion weldability test of joints under different modes showed the solidification cracking susceptibility lower in CMT-technique-based welds than MIG welds. temperature cycle pool recorded mini-thermocouples, which cooling rate samples samples. low promoted growth α-Al dendrites through back diffusion effect. Electron probe...
High-entropy diborides (HEDBs) have gained significant attention in industrial applications due to their vast composition space and tunable properties. We propose a solid solution reaction at high temperatures pressures that successfully synthesized sintered novel, dense, phase-pure HEDB (V
