ABSTRACT Conventional fault‐diagnosis methods, largely grounded in one‐dimensional signal analysis and linear modeling, often fail to detect complex nonlinear faults in rotating machinery operating under variable loads. Data‐driven approaches also face challenges in extracting discriminative information from high‐dimensional multisensor measurements ...

ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

ABSTRACT Accurate modeling of vibrating machines equipped with Neidhart springs is challenging due to the strong nonlinearities introduced by the elastomer–metal torsional elements and the constraints imposed by their kinematic arrangement. Multibody modeling methodologies for such vibrating machines are often computationally demanding, thus limiting ...

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Sliding Mode Control in Aerospace Applications: A Survey
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
