CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

Energy Conversion and Economics, EarlyView.Abstract Fast oscillations observed in wind farms and other renewable energy systems interfaced with power grids must be addressed promptly to prevent devastating shutdown and damage. Existing approaches mainly target high‐magnitude oscillations using data‐intensive convolutional neural networks (CNNs), leading to delayed detection and overlooking mild

Almost periodic solution of a discrete competitive system with delays and feedback controls
Open Mathematics, 2019 A discrete nonlinear almost periodic multispecies competitive system with delays and feedback controls is proposed and investigated. We obtain sufficient conditions to ensure the permanence of the system.

Boundedness in functional dynamic equations on time scales
Advances in Difference Equations, 2006 Using nonnegative definite Lyapunov functionals, we prove general theorems for the boundedness of all solutions of a functional dynamic equation on time scales.

IEEE AccessThe sampled-data asynchronous control problem for T-S fuzzy systems is investigated in this paper. Firstly, a new fuzzy Lyapunov functional that contains the fuzzy line integral function and an improved looped functional is constructed, in which two new ...

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
International Economic Review, EarlyView.ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

On Metric Choice in Dimension Reduction for Fréchet Regression
International Statistical Review, EarlyView.Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

Discretized Lyapunov functional for systems with distributed delay
, 1999 International audienceThe stability problem for systems with distributed delay is considered using discretized Lyapunov functional. The distributed delay is assumed to be piecewise constant, and the discretization mesh may be nonuniform.
