A dynamical system of the type homographic Ricker map is considered; this is a particular case of a new extended $$\gamma $$ -Ricker population model with a Holling type II per-capita birth function. The purpose of this paper is to investigate the no

In this work we investigate bifurcation structures in the chaotic domain of a piecewise linear bimodal map. The map represents a model of a circuit proposed to generate chaotic signals. For practical purposes it is necessary that the map generates ro

The rigorous proofs are given: (1) for the existence of the unbounded invariant curves, containing the fixed point – source (μ + 1; 1), of the maps from the one-parameter family Fμ(x,y) = (xy, (x − μ)2), μ ∈ [0, 2]; (2) for the birth of the

International audience; In this paper, we study the dynamics and bifurcation properties of a three-parameter family of 1D Gompertz's growth functions, which are defined by the population size functions of the Gompertz logistic growth equation. The dy

Publikováno v: IET Communications. 5:476-483

Transform domain communication systems (TDCSs) is a technology that avoids frequency underutilisation. Its bit error rate (BER) performance has been well studied until now, but it is still unknown what is the maximum spectrum efficiency one can expec
