The paper is focused on the development of the forecasting method for time series' groups with application of the clustering algorithms. Fuzzy c-means algorithm (FCM algorithm) is suggested to be a basic one for clustering. The coordinates of the clusters' centers have been put in correspondence with summarizing time se-ries data - the clusters' centroids. A description of time series, the clusters' cen-troids, is implemented with application of the forecasting models. They are based on the strict binary trees and the modified clonal selection algorithm. The forming possibility of analytic dependences with application of such forecasting models, is shown. It is suggested to use a common forecasting model, which is constructed for time series - the clusters' centroids, in forecasting for the private (individual) time series in the cluster. The use advantage of FCM algorithm in comparison with k-means algorithm for the clustering of time series' groups is shown. The promising application of the suggested forecasting method for forecasting of time series' groups is demonstrated. © 2015 Nadezhda N. Astakhova et al. Source

Robust chaos used in communication systems and communication. In the generated chaos in the case of a variation of parameters should not have periodicity windows. Besides, the dependence of older Lyapunov exponent is a function smoothly in wide range. A method of generating structural sustainable models based on the properties of weak violations of symmetries in the areas strange attractors. © 2014 IEEE. Source

Task simulation of dynamic chaos in the observed time series is given a lot of attention. Strange attractors are observed in many application processes. Therefore, the task of simulation is important for controlling and predicting in the dynamic behavior. In the article we consider the problem of constructing the model on the properties of the observed data. Requirements for the model are simulating signal quality with adequate properties of the original process. An efficient model that allows you to build a robust chaos developed. Computational examples are given here. © 2014 E. Nikulchev. Source

A method of 3D embossed printing is proposed where both point and line images can be printed on rigid polyvinyl chloride (PVC) shrink films without any consumables, such as paints, primers, dampening solutions, or washes. Embossed lettering and symbols on packaging are intended for people with poor vision, but capable of tactile marking recognition and reading Braille. This 3D printing is based on reversible deformation and stress relaxation in anisotropic glassy polymers by local isometric heat treatment of thermoplastic films under pressure. Films can be protected from counterfeiting by hidden markings due to time separation of information recording onto the film and displaying this information for visual or tactile reading. The results quantify the rate of internal stress relaxation in PVC shrink films at various stages of 3D printing, including tactile sign formation conditions. © 2015 Wiley Periodicals, Inc. Source
