A brief review of Protected Execution Mode (PEM) for user-space applications featured in Elbrus architecture is described first. Then, AddressSanitizer, a well-known utility by Google Inc, is considered as an example of a pure software technique of memory control. Comparative analysis of these solutions is given with performance flaws, applicability and boundary violation detection quality.
In the second generation digital video broadcast standards, such as DVB-T2, DVB-S2, DVB-C2, etc., is applied a powerful channel coding scheme to transmit data on the non-ideal communication channels with limited bandwidth due to the serial concatenation of BCH (Bose-Chaudhuri-Hocquenghen) and Low-Density-Parity-Check (LDPC) codes. The high-speed requirements, long data block lengths and multi-parametric...
We study the problem of vehicle scheduling in urban public transport systems taking into account the vehicle-type and size (VTSP). It is modeled as a multiobjective combinatorial optimization problem. A heuristic based on MOCell (Multi-Objective Cellular evolutionary algorithm) is proposed to solve the problem. A set of non-dominated solutions represents different assignments of vehicles to specific...
The paper gives an account of a historicmeeting held by the governing body of the USSRAcademy of Sciences Technology Division, whosedecisions played a key role in the development of Sovietcomputer engineering.
The article focuses on the issues of metrological support of large stationary antennas and, in particular, algorithms and methodologies for measuring the directional characteristics by using unmanned aircraft's self-consistent flight (flyby method) and GLONASS technologies. The article describes the experimental flyby measurements of the antenna under test (AUT) directional pattern at UHF range in...
The problems of subspace coding of large cardinality are considered. The main most interesting results which were published to this time are presented. A few directions of the development of this scientific area are mentioned. One of the direction was stated by Koetter, Kschischang and Silva and simultaneously was continued by Gabidulin and Bossert. It is based on so called lifting constructions of...
The article brings up the problem of tool support for the processes of learning and practical activities of surgeons using modern capabilities of information and telecommunication technologies. It discusses problems arising in the training of surgeons manipulating in the operating field of small dimensions, and similar problems of surgical care in a sparsely populated areas. The authors analyze the...
A possible variant of the signal processing for detection of weak pulsar signals is presented in this paper. The signal processing incudes three basic stages: epoch folding, moving average filter with a jumping window and adaptive signal detection. The signal processing proposed in the paper was verified with real experimental signal records from pulsar B0329+54 by the Westerbork Synthesis Radio Telescope...
The problem of detecting an unknown signal embedded in white Gaussian noise is addressed. The detector based on Wilcoxon signed-rank test is proposed as the solution for this problem. The detector analyses the spectrum of a received signal. Detection capability of this detector has been evaluated via mathematical modeling. Comparison with other prevalent detectors has been done.
Blended learning is a modern approach in education that can totally reshape academic environment. Another trend in education is Massive Open Online Courses (MOOCs) from leading universities or companies, such as Microsoft, Google, Dell Technologies, etc. Also many vendors (hardware and software companies) made its training available for lay public for free through traditional e-learning systems or...
Energy consumption represents a large percentage of the operational expenses in data centers. Most of the existing solutions for energy-aware scheduling are focusing on job distribution and consolidation between computing servers, while network characteristics are not considered. In this paper, we propose a model of power and network-aware scheduling that can be tuned to achieve energy-savings, through...
This article offers a general approach to developing methods of determining operation tolerances for the parameters' values of memristor-based artificial neural networks (ANNM), as a system that constitutes an united physical and informational object implemented by the hardware and software learning facilities. While looking for a solution to the issues of analysis and synthesis of this system's tolerances,...
A model of an X-band transmit-receive module was developed that was designed for definition of requirements to characteristics of an interconsistent set of monolithic microwave integrated circuits. The description of the model structure and the criteria for optimization of characteristics of MMIC included in the transmission and reception channels are given. The results of simulation of characteristics...
Two algorithms of the hybrid projection method corresponding to two polarizations are proposed for analysis of electromagnetic wave scattering by a radially inhomogeneous circular cylinder. The algorithms are based on projection matching of the fields on the boundaries of cylindrical regions, on projection of the appropriate Helmholtz equations on transverse functions, and on application of the one-dimensional...

In paper the parallel algorithm of number comparing in residue number system of the special form (2n-1, 2n, 2n+1) based on use of diagonal functions from work [5] and a method of the recursive doubling from work [9] is offered. The offered algorithm allows scoring 31% in area of the occupied device and 18% in time delay in comparing with algorithm from work [9].
Low detection accuracy of speech signal boundaries and pauses is one of the main problems of practical realization of diagnostic systems of psychogenic states. This paper proposes a noise-robust algorithm for 'speech/pause' segmentation, operating under free physical activity of a patient. In developing the algorithm the following methods were used: a method for adaptive processing of non-stationary...
