Proactive risk prediction in on-ramp merging with driving style recognition and multi-vehicle interaction analysis

Ying Min Yan, Xuan Zhou, Mo Zhou, Yuying Wang et autres

Freeway merging presents safety challenges due to dynamic vehicle interactions and diverse driver behaviors. Proactive risk prediction enables driver decisions and improves traffic safety. However, existing studies often neglect the role of pre-merge driving styles in shaping risk evolution and seldom account …

Research on 3D-BTC Signals Fractal Dimension Reconstruction Method of Aero-Engine

Ching‐Ting Tu, Xiaodong Zhang, Fei Dai

Turbine blades are key components of aero-engines. To comprehensively reflect the three-dimensional characteristics of the blades, the concept of three-dimensional blade tip clearance(3D-BTC) was proposed in our previous research. However, the 3D-BTC measurement signals is severely under-sampled due to the limitations of …

Visible‐Light‐Driven Photocatalytic Methanol Activation on Hexagonal CdS for Triggering C─H Methylation

Gang Chen, Lei Li, Yi Liu, Zhihao Li et autres

Abstract Light‐driven methanol activation paves the way for pursuing C─H methylation of N ‐heteroarenes, where selectively converting methanol into the corresponding hydroxymethyl radical (•CH 2 OH) is an essential prerequisite. Inspired by the versatile methanol activation on photoexcited solids, we here report …

Boosting Hot Electron Generation in Energy Center Embedded Metal–Organic Frameworks for Photocatalysis

Tian Shi, Zhihao Li, Wei Shao, Chao Yang et autres

The ligands in metal-organic framework (MOF) play as light absorption center and transfer photogenerated electrons to metal node through ligand-to-metal charge transfer (LMCT) during photocatalysis, and energy utilization efficiency is strongly restricted by the light inertness of ligands. Herein, a ligand updating …

Reinforcement Learning for Adversarial Environments

Christian Carrizales, Xiaodong Zhang, Trevor Bihl

This paper explores the development of more intelligent and competitive AI agents for adversarial environments. A hide and seek simulation environment with three sensor models is developed, including a lidar, a far filed sensor, and a near-filed sensor. Four AI vs AI …

Effect of Different Molten Salts on Structure and Water Splitting Performance of Al‐Doped Fillet Polyhedral SrTiO 3

Chuyu Wang, Qibo Jia, Xiaodong Zhang, Xi Chen et autres

Abstract Strontium titanium (SrTiO 3 ) is a promising photocatalyst, but enhancing the separation, migration, and utilization of photocarriers, requires SrTiO 3 with exposed anisotropic facets and minimal defect density. Here, we used NaCl and SrCl 2 as fluxes to synthesize fillet …
