47+ min ago   (479+ words) Hybrid artificial intelligence optimization models combine learned behavioral signals with constrained decision-making, but their transition from prototype calibration to operational use is rarely evaluated across changing platform regimes. The Adaptive Calibration and Operational Transferability (ACOT) framework separates the parameterized decision…...

1+ day, 3+ hour ago   (315+ words) Aiming at the difficulty of extracting fault features from nonlinear and non-stationary vibration signals of planetary gearboxes, a planetary gearbox fault diagnosis method based on Refined Composite Multiscale Fuzzy Entropy (RCMFE), Parametric-t-distributed Stochastic Neighbor Embedding (P-t-SNE), and Artificial Jellyfish Search…...

1+ day, 3+ hour ago   (478+ words) Cantilever roadheaders are widely used in medium-soft rock tunneling. However, conventional pick cutters suffer from high rock-breaking load, excessive energy consumption, and severe abrasion, which restrict the performance of roadheader vehicle-end intelligent control systems. Existing ultrasonic rock-breaking studies mainly focus…...

2+ day, 7+ hour ago   (375+ words) This study examined how different forms of tourism promotional materials are associated with visual attention and factual recall under natural viewing conditions. A total of 87 participants completed eye-tracking and memory-test tasks using text-only, image-only, and mascot–text composite promotional materials…...
