World city populations 1950–2030: Proportional circle time series map

On Circle Map Coupled Map Lattice

The circle map in one and two dimensions is studied. Both its stability and synchronization , using a bounded control and persistence, are discussed. This work is expected to be applicable in ecology where spatial effects are known to be important. Also, it will be relevant to systems where delay effects are not negligible.

Time series sightability modeling of animal populations

Logistic regression models-or "sightability models"-fit to detection/non-detection data from marked individuals are often used to adjust for visibility bias in later detection-only surveys, with population abundance estimated using a modified Horvitz-Thompson (mHT) estimator. More recently, a model-based alternative for analyzing combined detection/non-detection and detection-only data was deve...

A Generalization of Initial Conditions in Benchmarking of Economic Time-Series by Additive and Proportional Denton Methods

The paper presents unified analytical solution for combining high-frequency and low-frequency economic time-series by additive and proportional Denton methods with parametrical dependence on the initial values of variable and indicator in evident form. This solution spans Denton’s original and Cholette’s advanced benchmarking initial conditions as the subcases. Computational complexity of the o...

Elementary properties of circle map sequences

We study the combinatorial and structural properties of the circle map sequences. We introduce an embedding procedure which gives a map Φ : Ω → W := {R,L} from the hull(closure of the set of translates) to the sequence of embedding operations through which we study the structure of Ω. We also study the set of admissible words and classify them in terms of their appearance. Mathematics Subject C...
