Spatial time-series modeling with R system

open access: yesLietuvos Matematikos Rinkinys, 2004
In this paper we propose modeling technique, which was applied to multivariate time series data that correspond to different spatial locations (spatial time series). ARIMA model class is considered for each location.

Assessing pricing assumptions for weather index insurance in a changing climate

open access: yesClimate Risk Management, 2014
Weather index insurance is being offered to low-income farmers in developing countries as an alternative to traditional multi-peril crop insurance. There is widespread support for index insurance as a means of climate change adaptation but whether or not

Beta-gamma system, pure spinors and Hilbert series of arc spaces [PDF]

open access: yes, 2015
Algorithms are presented for calculating the partition function of constrained beta-gamma systems in terms of the generating functions of the individual fields of the theory, the latter obtained as the Hilbert series of the arc space of the algebraic ...

Time series forecasting using a TSK fuzzy system tuned with simulated annealing [PDF]

open access: yes, 2010
In this paper, a combination of a Takagi-Sugeno fuzzy system (TSK) and simulated annealing is used to predict well known time series by searching for the best configuration of the fuzzy system.

MODELING TIME SERIES DATA OF REAL SYSTEMS [PDF]

open access: yesInternational Journal of Modern Physics C, 2007
Dynamics of complex systems is studied by first considering a chaotic time series generated by Lorenz equations and adding noise to it. The trend (smooth behavior) is separated from fluctuations at different scales using wavelet analysis and a prediction method proposed by Lorenz is applied to make out of sample predictions at different regions of the

On a problem of Gevorkyan for the Franklin system [PDF]

open access: yesOpuscula Mathematica, 2016
In 1870 G. Cantor proved that if \(\lim_{N\rightarrow\infty}\sum_{n=-N}^N\,c_{n}e^{inx} = 0\) for every real \(x\), where \(\bar{c}_{n}=c_{n}\) (\(n\in \mathbb{Z}\)), then all coefficients \(c_{n}\) are equal to zero. Later, in 1950 V. Ya. Kozlov proved

Nonlinear system modeling based on constrained Volterra series estimates

open access: yes, 2017
A simple nonlinear system modeling algorithm designed to work with limited \emph{a priori }knowledge and short data records, is examined. It creates an empirical Volterra series-based model of a system using an $l_{q}$-constrained least squares algorithm
