Webb28 nov. 2024 · Stochastic systems can be widely adopted for describing practical complex systems, such as meteorology. Recently, there have been many advances in the design of stochastic systems, including system modeling, control, estimation, performance enhancement, and industrial applications. Motivated by these results, this Special Issue … Webbin research [14{16]. The optimization phenomenon of hysteretic structures due to the stochastic resonance has already been reported earlier with regard to bistable and multistable potentials [17, 18], neural networks [19] and has been also formally studied in [20]. In this paper we will make a connection between the \stochastic memory"
