Software-defined-radio (SDR) becomes an attractive technique for the development of GNSS receivers due to universal hardware and high flexibility. However, the performance of signal processing can be a challenging task. Real-time mode implementation requires fast floating point calculations in several threads, not available for most part of embedded systems. This paper describes the system-on-chip based device drastically increasing computational performance. A summary of computational complexity of each stage of GNSS receiver is provided and several particular solutions are proposed.

A large amount of data is generated during the operation of oil fields. Such data can be both data already interpreted by a specialist, or "raw” data obtained directly from the devices, both structured and not structured, or locally structured (that is, allowing for local analysis, but in such form not allowing analyzing in conjunction with other types of data). To obtain from such a set of more informative data that will allow making decisions in the course of field operation, it is necessary to involve specialists from different areas of the oil industry. Therefore, it is possible and necessary to use non-deterministic methods for analyzing the data obtained. The article discusses the use of machine learning methods in the task of determining the initial water-cut based on well logging data.

One of the important tasks facing the regional authorities is to monitor the condition of roads and power lines. In the Ulyanovsk region more than 8 thousand km of power lines and more than 9 thousand km of roads (including rural). A significant part of these facilities is located outside the settlements in places with medium and low availability. In many such places there is a problem of uncontrolled forest overgrowth. This work is devoted to solving the problem of automated satellite monitoring of such areas. For this purpose, it is proposed to use a modified convolutional neural network that processes time sequences of multispectral satellite images and allows to allocate territories occupied by forest and undergrowth with high accuracy. This approach allows us to assess the dynamics of overgrowth of the territory and perform the appropriate forecast with sufficient accuracy for practice.

The paper deals with the development of mathematical models of random fields to describe and simulate images. In the wave model, a random field is the result of the influence of perturbations (waves) that occur at random times in random places and have random shapes. This model allows representing and simulate isotropic and anisotropic images (and their temporal sequences) defined on arbitrary areas of multidimensional space, as well as on any surfaces. The problems of correlation analysis and synthesis can be relatively easily solved. However, this model allows representing only homogeneous fields. In this paper, we consider «double stochastic» wave models, when the first wave random field (control field) sets the parameters of the second (controlled field). As a result, the controlled field becomes nonuniform, since its parameters vary randomly. We also consider options when two fields mutually influence each other. These models allow us to represent and simulate multidimensional inhomogeneous images (and their temporal sequences), as well as systems of such images with mutual correlations.

In this paper, we discuss various options for implementing the ”Kuznyechik” block encryption algorithm using the NVIDIA CUDA technology. We use lookup tables as a basis for the implementation. In experiments, we study the influence of the size of the block of threads and the location of lookup tables on the encryption speed. We show that the best results are obtained when the lookup tables are stored in the global memory. The peak encryption speed reaches 30.83 Gbps on the NVIDIA GeForce GTX 1070 graphics processor.

The potential of correlation-based feature selection has been explored in selecting an optimal subset from a set of highly correlated predictors. This problem occurs, for example, in time series forecasting of economic indicators using regression models on multiple lags of a large number of candidate leading indicators. Greedy algorithms (forward selection and backward elimination) in such cases fail. To obtain the globally optimal solution, the feature selection problem is formulated as a mixed integer programming problem. To solve it, we use the binary cut-and-branch method. The results of simulation studies demonstrate the advantage of using the binary cut-and-branch method in comparison with heuristic search algorithms. The real example of the selection of leading indicators of consumer price index growth shows the acceptability of using the correlation-based feature selection method.

According to the Federal State Statistics Service for 2017, over 25,000 injuries at work were registered in Russia, of which 1,138 were fatal. Studies have shown that most of the injuries in the workplace due to non-compliance with technical safety rules, namely the lack of personal protective equipment or their improper use. To improve the efficiency of monitoring compliance with the rules of technical safety at industrial facilities, this paper discusses the use of vision systems for automatic control of the availability of personal protective equipment at workers in the area of industrial work.

Currently, unwanted emails are actively sent to the Internet. Millions copies of emails are sent simultaneously to various users. Often e-mails undergo minor modifications to complicate the detection of spam. The paper proposes options for determining the signature of e-mails that allow identify letters with the same content and structure. Content signature of the letter includes the basic phrases in the text of the e-mail with the exception of names, numeric codes, suspicious words that are not included in the dictionary. Structure signatures incorporate the same type of e-mails, such as paragraphs, tables, images. The paper shows the results of using signatures to detect e-mail spam.
