Bearing Fault Diagnosis Using Refined Composite Generalized Multiscale Dispersion Entropy-Based Skewness and Variance and Multiclass FCM-ANFIS

Entropy, 2021
Bearing vibration signals typically have nonlinear components due to their interaction and coupling effects, friction, damping, and nonlinear stiffness. Bearing faults affect the signal complexity at various scales.

Refined Composite Multiscale Fuzzy Dispersion Entropy and Its Applications to Bearing Fault Diagnosis

Entropy, 2023
Rotary machines often exhibit nonlinear behavior due to factors such as nonlinear stiffness, damping, friction, coupling effects, and defects. Consequently, their vibration signals display nonlinear characteristics.

An end-to-end data-driven optimization framework for constrained trajectories

Data-Centric Engineering, 2022
Many real-world problems require to optimize trajectories under constraints. Classical approaches are often based on optimal control methods but require an exact knowledge of the underlying dynamics and constraints, which could be challenging or even out

Modal descent [PDF]

Mathematical Structures in Computer Science, 2020
AbstractAny modality in homotopy type theory gives rise to an orthogonal factorization system of which the left class is stable under pullbacks. We show that there is a second orthogonal factorization system associated with any modality, of which the left class is the class of ○-equivalences and the right class is the class of ○-étale maps.

Syntax/Semantics discrepancy in the grammaticalization of resultatives: Evidence from Karimata-Miyako Ryukyuan

Glossa, 2022
I present clear evidence from Karimata-Miyako Ryukyuan that semantic change can precede a syntactic change in the process of grammaticalization. In this dialect, the morpheme ufu has an aspectual and a conjectural use, and the change proceeds from the ...

From industry-wide parameters to aircraft-centric on-flight inference: Improving aeronautics performance prediction with machine learning

Data-Centric Engineering, 2020
Aircraft performance models play a key role in airline operations, especially in planning a fuel-efficient flight. In practice, manufacturers provide guidelines which are slightly modified throughout the aircraft life cycle via the tuning of a single ...
