Applications of double bond indices: Quantitative characterization of properties of benzenoid hydrocarbons

Topological indices (TIs) are widely used descriptors in QSAR/QSPR modeling, but conventional degree-based TIs neglect bond multiplicity, potentially limiting structural resolution. Thirteen extended double-bond-corrected TIs were derived via a Kekuúlé-structure-based edge classi...

A fixed-time fault-tolerant tracking control for fractional-order UAV networks using adaptive fuzzy neural and event-triggered mechanisms

Abstract This paper investigates coordinated tracking control for fractional-order fixed-wing unmanned aerial vehicle (UAV) networks subject to actuator faults, input saturation, unknown nonlinear dynamics, external disturbances, and communication constraints. A dynamic memory ev...
