The bistability of higher-order differences of discrete periodic signals
Advances in Differential Equations, 2014 A theorem on higher-order absolute differences taken from successive terms of bounded sequences is proved. This theorem establishes the property of bistability of such difference series and suggests a method for converting periodic discrete-time signals ...

Nonlinear Cointegration and Nonlinear Error Correction: Record Counting Cointegration Tests [PDF]
, 2006 In this article we propose a record counting cointegration (RCC) test that is robust to nonlinearities and certain types of structural breaks. The RCC test is based on the synchronicity property of the jumps (new records) of cointegrated series, counting

Some ideas on nonlinear musical analysis
, 2013 In this article we use time series analysis methods such as recurrence quantification analysis, estimation of the correlation dimension and Liapunov exponents to study three different musical compositions.

Recursiveness in Hilbert spaces and application to mixed $ARMA(p,q)$ process
, 2014 In this paper, the gap between the nonhomogeneous linear recurrence relation and the mixed ARMA(p; q) process in Hilbert spaces is provided. We focus ourselves on the case when the ARMA(p; q) process is of Fibonacci type. Notably, involving properties of

Sparse Time Frequency Representations and Dynamical Systems [PDF]
, 2015 In this paper, we establish a connection between the recently developed data-driven time-frequency analysis [T.Y. Hou and Z. Shi, Advances in Adaptive Data Analysis, 3, 1–28, 2011], [T.Y. Hou and Z. Shi, Applied and Comput. Harmonic Analysis, 35, 284–308,

Using a Bayesian change-point statistical model with autoregressive terms to study the monthly number of dispensed asthma medications by public health services [PDF]
, 2018 In this paper, it is proposed a Bayesian analysis of a time series in the presence of a random change-point and autoregressive terms. The development of this model was motivated by a data set related to the monthly number of asthma medications dispensed ...

Dynamical Sieve of Eratosthenes
, 2011 In this document, prime numbers are related as functions over time, mimicking the Sieve of Eratosthenes. For this purpose, the mathematical representation is a uni-dimentional time line depicting the number line for positive natural numbers N, where each

A fractal set from the binary reflected Gray code [PDF]
, 2005 The permutation associated with the decimal expression of the binary reflected Gray code with N bits is considered. Its cycle structure is studied. Considered as a set of points, its self-similarity is pointed out.

Kernel estimates of nonparametric functional autoregression models and their bootstrap approximation
, 2017 This paper considers a nonparametric functional autoregression model of order one. Existing contributions addressing the problem of functional time series prediction have focused on the linear model and literatures are rather lacking in the context of ...

A Bayesian Networks Approach to Operational Risk
, 2010 A system for Operational Risk management based on the computational paradigm of Bayesian Networks is presented. The algorithm allows the construction of a Bayesian Network targeted for each bank using only internal loss data, and takes into account in a ...
