Many non-linearity tests have been developed to apply on specific time series, but non of the tests has proved uniformly most powerful; depending on the situation another test may perform better in distinguishing between truly linear and non-linear series. In this context, Peña and Rodriguez circumvent the philosophical question as to the nature of non-linearity in order to find and develop a n...

Fuzzy sets constitute the oldest and most reported soft computing paradigm. They are well-suited to modeling different forms of uncertainties and ambiguities, often encountered in real life. Integration of fuzzy sets with other soft computing tools has lead to the generation of more powerful, intelligent and efficient systems. In this position paper we seek to outline the contribution of fuzzy ...

We explain how to apply statistical techniques to solve several language-recognition problems that arise in cryptanalysis and other domains. Language recognition is important in cryptanal-ysis because, among other applications, an exhaustive key search of any cryptosystem from ciphertext alone requires a test that recognizes valid plaintext. Written for cryptanalysts, this guide should also be ...
