Relationship between the observability of standard and fractional linear systems

open access: yesArchives of Control Sciences, 2017
The relationship between the observability of standard and fractional discrete-time and continuous-time linear systems are addressed. It is shown that the fractional discrete-time and continuous-time linear systems are observable if and only if the ...

Synchronization of Discrete-Time Fractional-Order Complex-Valued Neural Networks with Distributed Delays

open access: yesFractal and Fractional, 2023
This research investigates the synchronization of distributed delayed discrete-time fractional-order complex-valued neural networks. The necessary conditions have been established for the stability of the proposed networks using the theory of discrete ...

Classical stochastic discrete time crystals [PDF]

open access: yesPhysical Review E, 2019
We describe a possible general and simple paradigm in a classical thermal setting for discrete time crystals (DTCs), systems with stable dynamics which is subharmonic to the driving frequency thus breaking discrete time-translational invariance. We consider specifically an Ising model in two dimensions, as a prototypical system with a phase transition ...

Asymptotic results for the first and second moments and numerical computations in discrete-time bulk-renewal process [PDF]

open access: yesYugoslav Journal of Operations Research, 2019
This paper introduces a simplified solution to determine the asymptotic results for the renewal density. It also offers the asymptotic results for the first and second moments of the number of renewals for the discrete-time bulk-renewal process.

Robust Stability Analysis of Switching Time-Delay Systems via a Novel Non-Monotonic Lyapunov–Krasovskii Approach [PDF]

open access: yesInternational Journal of Research and Technology in Electrical Industry
In this paper, a novel approach based on a non-monotonic Lyapunov–Krasovskii functional is first proposed for the comprehensive stability analysis of discrete-time switched systems with time delays in an m-step-ahead scheme.

Dynamic Limit Growth Indices in Discrete Time [PDF]

open access: yes, 2014
We propose a new class of mappings, called Dynamic Limit Growth Indices, that are designed to measure the long-run performance of a financial portfolio in discrete time setup.
