The market of EO services is rapidly growing and becoming one of the main driving forces of innovative development both in Europe and Russia. At the same time, still the exchange of EO data available in both regions is a technical challenge. The consortium composed of the developers of an only Russian civil EO satellite system Resurs-DK and representatives of European EO research community and EO service industry aims at reducing technical barriers for the joint use of EO data available both in the EU and Russia. In particularly, the project will (1) structure and make publically available internal data format used in the Resurs satellite system, (2) develop mathematical methods for data conversion and several software toolboxes enabling independent EO service providers and GIS developers to access to and use both European and Russian EO datasets from a single application, (3) develop the web interface for the collections of the Resurs satellite data, thus enabling access to and efficient search for EO images. The major technical outcomes will be tested and evaluated by integration into the real European and Russian applications and their validation in the context of provisioning real services to potential final users. The consortium will also undertake steps to make the project results available to the prime dissemination audience - SMEs working in the field of EO services and/or GIS software development.

This paper represents an approach for object's classification based on the combined implementation of the SVM algorithm and the fuzzy clustering algorithms. It is offered to use the fuzzy clustering algorithms’ ensemble based on the clusters’ tags’ vectors’ similarity matrixes and the spectral factorization algorithm as for creation the training and test sets, used for development of SVM classifier, as for specification of the clustering results with application of the trained SVM classifier. In the first case we solve an absence problem of aprioristic information on objects’ possible class association and avoid inclusion of noise objects in the training and test sets, that will provide development of more exact SVM classifier. In the second case we use part of the clustering results received by means of the fuzzy clustering algorithms’ ensemble for training of SVM classifier, and another-for the specification of the clustering results by means of the trained SVM classifier. We use in the spectral factorization algorithm along with the k-means algorithm, which is usually applied to graph splitting into clusters, the FCM algorithm, allowing to reduce the cost of graph splitting and receive better graph splitting into clusters, that will provide higher quality of objects’ classification. © 2015 Praise Worthy Prize S.r.l. - All rights reserved.

We consider flows in networks analogous to numerical flows but such that values of arc capacities are elements of a lattice. We present an analog of the max-flow min-cut theorem. However, finding the value of the maximum flow for lattice flows is based on not this theorem but computations in the algebra of matrices over the lattice; in particular, the maximum flow value is found with the help of transitive closure of flow capacity functions. We show that there exists a correspondence between flows and solutions of special-form systems of linear equations over distributive lattices. © 2016, Pleiades Publishing, Inc.

A novel method for the power azimuth spectrum (PAS) estimation in correlated fading channel is proposed. The method is based on the inverse problem solution regarding Fourier basis coefficients of the PAS. The input data is a set of complex correlation coefficients which can be obtained by using a multi-element antenna (MEA) consisting of specially arranged mutually uncoupled thin vibrators those are omnidirectional in the azimuth plane. The proposed method also allows to interpolate the spatial correlation function (SCF) over a bounded area of a MEA setup. The impact of the MEA arrangement on estimation accuracy is also considered. © 2015 German Institute of Navigation (DGON).

The article discusses the creation of automated system for correction of negative functional states of production workers on the basis of application equipment USB-6008 and the programming environment LabVIEW National Instruments. The USB-6008 is used for the removal of bioelectric signals worker whose analysis is a virtual instrument used to assess the presence of negative conditions and issue the necessary corrective action. Describes the version of the implementation of the automated system. © 2015 IEEE.

The results of strapdown inertial navigation system (SINS) tests with 9 degrees of freedom MEMS sensor MPU-9150 (triaxial accelerometer, gyroscope and magnetometer), pressure sensor LPS331 and ultrasonic range meter HC-SR04, implemented on the FPGA Altera Cyclone-II evaluation board DE1 is considered. SINS measures the spatial coordinates and altitude relative to the starting point, the orientation angles and distances to obstacles along the way. It is shown that the relative error of the spatial coordinates estimation does not exceed 1.1% in interval of some minutes. © Published under licence by IOP Publishing Ltd.

This paper deals with the problem of intermodulation interferences in the receiving path of active antenna array. The author proposes to mitigate the problem of intermodulation interferences by means of spatio-Temporal compensation algorithms, based on estimation-correlation-compensation signal processing, and spatial compensation algorithm, based on linear adaptive array technique. © 2015 IEEE.

Some investigation results, directed to the creation of sealed-off TEA-CO2 laser with pulse repetition rates from 1 to 5 kHz for technological applications are given. In TEA-CO2 laser with active volume V =28×0,5×2 cm3 maximum values of radiation energy per pulse 20÷25 mJ at 2÷3 kHz are obtained. At the 5 kHz the laser energy decreases up to 5÷6 mJ. Perspectives of increasing of pulse repetition rates up to 20 kHz are discussed. © 2016 IEEE.

Paper develops a perturbation theory for description of ion motion in quadrupole radio frequency (RF) field. First order corrections for the ion phase coordinates caused by field perturbations over one period of the RF field are derived. Transformation matrix of the phase coordinates over one RF period is obtained and stability parameter of the perturbed ion motion is defined in the first order approximation. Results are applied for investigation of stability diagram of ion motion in a quadrupole mass filter. Boundaries of stability are defined in linear approximation and resolving power dependence from the slope of the operating line is obtained. In contrast to previously known results current approach allows obtaining corresponding dependences in semi analytical form expressed in terms of unique solutions of Mathieu equation at the tip of stability. © 2012 Elsevier B.V.
