The evolutionary development of railway power-supply systems and computer networks and technologies that control these systems are analyzed. It is shown that the optimization of electricity consumption is based on the intellectualization of electricity supply procedures. A graph is constructed whose topology adequately represents the typical architecture of a computer network of control at the layer of a distance of power supply of railways with a view to investigating the mutual integration of a power supply infrastructure and a computer network architecture of all-mode control. This article proposes a differential mathematical model for investigating the computer network architecture of an all-mode system of control over a distance of power supply and methods (in analytical form) for determining values of probabilities of states of system nodes, their capacities, and the number of failures of requests as the basis for the intellectualization of power supply procedures. © 2017 Springer Science+Business Media New York

A classification of correlation algorithms is provided. A method of S-preparation is discussed, which, due to the preliminary conveyor formation of correlated image convolution sums, is characterised by high noise immunity and adaptivity to uncertainty and variability of the signal clutter situation.

This article analyzes the current state of scientific investigations in the sphere of intellectualization of electrical networks on the basis of synchronous phasor measurements in a system of registration of primary data. The optimization of electrical energy consumption is shown to be dependent on the informational completeness of primary multidimensional data. Based on differential transformations, mathematical models and methods are proposed to analytically compute a collection of T-discretes for determining the informational completeness of the obtained nondeterministic primary data. Methods are considered that make it possible to intellectualize technologies of synchronous phasor measurements with the help of representation of registered primary data in the form of T-spectra for determining individual harmonic components for each parameter of transient processes in power supply systems and also for performing spectral analysis (based on differential representations) and computing spectral density as the basis for the formation and accumulation of new knowledge. © 2016 Springer Science+Business Media New York

The paper presents a method of parallel-hierarchical transformations for rapid recognition of dynamic images using GPU technology. Direct parallel-hierarchical transformations based on cluster CPU-and GPU-oriented hardware platform. Mathematic models of training of the parallel hierarchical (PH) network for the transformation are developed, as well as a training method of the PH network for recognition of dynamic images. This research is most topical for problems on organizing high-performance computations of super large arrays of information designed to implement multi-stage sensing and processing as well as compaction and recognition of data in the informational structures and computer devices. This method has such advantages as high performance through the use of recent advances in parallelization, possibility to work with images of ultra dimension, ease of scaling in case of changing the number of nodes in the cluster, auto scan of local network to detect compute nodes. © 2016 SPIE.
