System Uncertainty Effects on the Wave Frequency Response Of Floating Vessels Based on Polynomial Chaos Expansion

open access: yesVolume 2: Structures, Safety, and Reliability, 2021
From a mathematical viewpoint, the frequency domain analysis of vessel motion responses due to wave actions incorporates the integration of system dynamics idealized in terms of response amplitude operators (RAOs) for 6 DOF rigid body motions and an ...

Rate-dependent tipping and early warning in a thermoacoustic system under extreme operating environment.

open access: yesChaos, 2021
Thermoacoustic instability has been an important challenge in the development of high-performance combustion systems, as it can have catastrophic consequences. The process of a sudden change in the dynamical behavior of a thermoacoustic system from a low-

Electro-optic chaos system with time delay signature concealment based on XOR operation and multi-bit PRBS

open access: yesOptics Express, 2021
A novel chaos system with XOR operations and multi-bit PRBS is proposed to improve the sequence complexity and the security of the classic electro-optic intensity chaos system. Through the bifurcation diagram and permutation entropy analysis, the PE can be increased to 0.99.

Effect of Ordering Policies on Complex Dynamics Behaviours in a Discrete-Type Manufacturing Industry Supply Chain System

open access: yesChinese Journal of Mechanical Engineering, 2018
The beer game model is a typical paradigm used to study complex dynamics behaviours in production–distribution systems. The model, however, does not accord with current practical supply chain system models in discrete-type manufacturing industry, which ...

Over-limit risk assessment method of integrated energy system considering source-load correlation

open access: yesGlobal Energy Interconnection, 2023
In an integrated energy system, source-load multiple uncertainties and correlations lead to an over-limit risk in operating state, including voltage, temperature, and pressure over-limit. Therefore, efficient probabilistic energy flow calculation methods
