Damage Identification in Moment Frames Using Mode Shape Parameters and IMRFO Algorithm [PDF]
This study presents a novel finite element model updating approach for accurate damage identification in moment-resisting frames. The proposed objective function, which integrates mode shape parameters with natural frequencies, demonstrates high ...

Image encryption scheme based on compressed sensing and fractional quantum logistic-tent map
In this paper, we construct a quantum logistic-tent map and extend it to the fractional order. Using bifurcation portrait, Lyapunov exponent spectrum, and spectral entropy, its nonlinear characteristics are investigated.

A Novel Chaotic Map and an Improved Chaos-Based Image Encryption Scheme
In this paper, we present a novel approach to create the new chaotic map and propose an improved image encryption scheme based on it. Compared with traditional classic one-dimensional chaotic maps like Logistic Map and Tent Map, this newly created ...

On the dynamics of skew tent maps
In this paper we give an elementary treatment of the dynamics of skew tent maps. We divide the two-parameter space into six regions. Two of these regions are further subdivided into infinitely many regions. All of the regions are given explicitly. We find the attractor in each subregion, determine whether the attractor is a periodic orbit or is chaotic,

Closure measures for coarse-graining of the tent map
We quantify the relationship between the dynamics of a time-discrete dynamical system, the tent map T and its iterations Tm, and the induced dynamics at a symbolical level in information theoretical terms. The symbol dynamics, given by a binary string s of length m, is obtained by choosing a partition point α∈[0,1] and lumping together the points x∈[0 ...

Parameter Estimation of a Class One-Dimensional Discrete Chaotic System
It is of vital importance to exactly estimate the unknown parameters of chaotic systems in chaos control and synchronization. In this paper, we present a method for estimating one-dimensional discrete chaotic system based on mean value method (MVM).
