A New Fractional-Order Map with Infinite Number of Equilibria and Its Encryption Application

Complexity, 2022
The study of the chaotic dynamics in fractional-order discrete-time systems has received great attention over the last years. Some efforts have been also devoted to analyze fractional maps with special features.

Robust Output Feedback Consensus for Networked Identical Nonlinear Negative-Imaginary Systems [PDF]

arXiv, 2020
A robust output feedback consensus problem for networked identical nonlinear negative-imaginary (NI) systems is investigated in this paper. Output consensus is achieved by applying identical linear output strictly negative-imaginary (OSNI) controllers to all the nonlinear NI plants in positive feedback through the network topology. First, we extend the

Nonlinear gauge transformation for a class of Schroedinger equations containing complex nonlinearities [PDF]

Rep. Math. Phys. 46, 113 (2000), 2002
We consider a wide class of nonlinear canonical quantum systems described by a one-particle Schroedinger equation containing a complex nonlinearity. We introduce a nonlinear unitary transformation which permits us to linearize the continuity equation.

Absence Seizure Control by a Brain Computer Interface

Scientific Reports, 2017
The ultimate goal of epileptology is the complete abolishment of epileptic seizures. This might be achieved by a system that predicts seizure onset combined with a system that interferes with the process that leads to the onset of a seizure.

Parametric characteristic analysis for the output frequency response function of nonlinear volterra systems [PDF]

, 2006
The output frequency response function (OFRF) of nonlinear systems is a new concept, which defines an analytical relationship between the output spectrum and the parameters of nonlinear systems. In the present study, the parametric characteristics of the

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

A new method to reduce the number of time delays in a network

Scientific Reports, 2017
Time delays may cause dramatic changes to the dynamics of interacting oscillators. Coupled networks of interacting dynamical systems can have unexpected behaviours when the signal between the vertices are time delayed.

The equivalent nonlinearity for a nonlinear system with dither

Journal of Mathematical Analysis and Applications, 1973
AbstractGiven a single loop nonlinear control system. The problem of constructing a dither signal in order to obtain a desired equivalent nonlinearity is considered. It is assumed that the nonlinearity may be described by a kth order polynomial. For this case it is shown that in general k different levels for the dither signal are necessary.
