We propose a nouvel methodology for forecasting chaotic systems which uses information on local Lyapunov exponents (LLEs) to improve upon existing predictors by correcting for their inevitable bias. Using simulations of the Rössler, Lorenz and Chua attractors, we find that accuracy gains can be...

It is said that theories explain laws, and laws are facts of observation. At the first sight these two concepts reduced to axioms are perfectly logical and consistent, but the law is a valid creation only in an unit of time, starting with the laws of physics and finishing with the ones of...

We investigate the existence of nonlinearities in the dynamics of the returns of stock markets indices from CEE economies. We use several types of nonlinear tests. We discuss the implications of the results with respect to the efficient market hypothesis.

This article presents an exhaustive analysis of the normal distribution assumption in terms of emerging capital markets. The accuracy of such assumptions is fundamentally contested by the results of empirical analysis. In addition, this paper is also a conceptual debate between classical theory...

Chaotic phenomena, chaos amplification and other interesting nonlinear behaviors have been observed in supply chain systems. Chaos can be defined theoretically if the dynamics under study are produced only by deterministic factors. However, deterministic settings rarely present themselves in...

This paper investigates the behaviour of weekly hardware sales in the Japanese video game sector. It is found that weekly hardware sales exhibit significant linear and non-linear behaviours during the product cycle. We are going to analyse the implications of our findings for management control...

We examine the effect of two specific noises on a dynamical system. We obtain consistent estimates with their rates of convergence for the invariant density for such a model. Some simulations are provided.

The literature on tourism development has focused on a one dimensional relationship between tourism development and quality of life. The impact of shock events on the relationship tourism development and quality of life seems ignored. Rather less attention has been paid to the multi-dimensional...

Risk is considered as an important issue in hazardous materials routing problems, in particular once a certain part of the road network has been affected by natural disasters. It could even be a more serious concern when vital hazmat substances, are required to be transported to the affected...
