DOI: 10.1103/physrevb.98.134204

Abstract: We consider a random time evolution operator composed of a circuit of random unitaries coupling even and odd neighboring spins on a chain in turn. In spirit of Floquet evolution, the circuit is time-periodic; each… read more here.

recommendations! Published in 2023 at "IEEE Transactions on Industrial Electronics"

DOI: 10.1109/tie.2022.3186335

Abstract: Load frequency control (LFC) of modern power systems tends to employ open communication networks to transmit measurement/control signals, which makes the LFC scheme more vulnerable to random time delays and time-delay attacks (TDAs). In this… read more here.

DOI: 10.1109/tii.2024.3399473

Abstract: The transmission losses exist in power systems, and the communication network of smart grids is not fixed and reliable because of the intermittency of distributed renewable generations, packet loss, and uncertainty. Taking the issues into… read more here.

DOI: 10.1109/tnse.2023.3294414

Abstract: In this article, a special class of distributed stochastic nonconvex optimization problem is investigated. Each agent in the network only has access to a local stochastic weakly convex objective function and can only communicate with… read more here.

DOI: 10.1109/tsp.2017.2706186

Abstract: Graph filters play a key role in processing the graph spectra of signals supported on the vertices of a graph. However, despite their widespread use, graph filters have been analyzed only in the deterministic setting,… read more here.

DOI: 10.1155/2018/5636541

Abstract: A probability-weighted optimal control strategy for nonlinear stochastic vibrating systems with random time delay is proposed. First, by modeling the random delay as a finite state Markov process, the optimal control problem is converted into… read more here.
