We revisit the model of endogenous credit cycles by Matsuyama (2013, Sections 2–4). First, we show that the same dynamical system that generates the equilibrium trajectory is obtained under a much simpler setting. Such a streamlined presentation should help to highlight the mechanism through which financial frictions cause instability and recurrent fluctuations. Then, we discuss the nature of f...

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 . It is proposed by exploiting the ergodic and synchronization features of chaos. It can effectively estimate the parameter value, and it is more exac...

Chaos optimization algorithms (COAs) usually utilize different chaotic maps(logistic, tent, Hénon, Lozi,...) to generate the pseudo-random numbers mapped as design variables for global optimization. In this paper we are going propose new technique improve algorithm by using some transformations modify density of map instead changing it.

In this paper generation of binary sequences derived from chaotic sequences defined over Z4 is proposed. The six chaotic map equations considered in this paper are Logistic map, Tent Map, Cubic Map, Quadratic Map and Bernoulli Map. Using these chaotic map equations, sequences over Z4 are generated which are converted to binary sequences using polynomial mapping. Segments of sequences of differe...

Abstract Chaos i s introduced to cryptology. As an example of the applications, a secret key cryptosystem by iterating a one dimensional chaotic map i s proposed. This system is based on the characteristics of chaos, which are sensitivity of parameters, sensitivity of initial points, and randomness of sequences obtained by iterating a chaotic map. A ciphertext is obtained by the iteration of a ...

Nowadays, using transfer information includes images has increased due to increasing use of computer demands. Chaos-based image encryption method is one of the most efficient methods which is used to hide visual information during transmission. This paper presents a new image encryption method based on Logistic and Tent chaotic maps and permutation-diffusion architecture, in which, chaotic maps...
