On stationarity and second-order properties of bilinear random fields

Bibi, Abdelouahab; Kimouche, Karima - In: Statistical Inference for Stochastic Processes 17 (2014) 3, pp. 221-244

One-dimensional indexed bilinear (BL) models are widely used for modeling non Gaussian time series. Extending BL models to multidimensional indexed (spatial) SBL one, yields a novel class of models which are capable of taking into account the important characteristic of non Gaussianity and...

Transfer functions of solar collectors for dynamical analysis and control design

Buzás, J.; Kicsiny, R. - In: Renewable Energy 68 (2014) C, pp. 146-155

In view of system efficiency and environmental protection, it is of primary importance to harvest solar energy better and better for example by means of developing solar collectors. Mathematical modelling is the theoretically established tool for it, for example with using the collector transfer...

Self Projecting Time Series Forecast: an Online Stock Trend Forecast System

Deng, K; Shen, H.T.; Tian, H - 2006

This paper explores the applicability of time series analysis for stock trend forecast and presents the Self projecting Time Series Forecasting (STSF) System which we have developed. The basic idea behind this system is the online discovery of mathematical formulae that can approximately...
