The need to develop a wider range of methods and tools for system analysis and modeling, allowing to develop and implement anti-terrorism measures, was noted. The results of a model analysis of terrorist activity in media space are presented. The research is based on already approved model solutions. It is proposed to use the combination and integration of humanitarian knowledge and natural science tools. A cognitive analysis of the communication model of a successful terrorist attack and models of proactive counteraction to terrorist threats was carried out. Models are single- or multi-loop schemes with positive or multidirectional feedbacks. Functional-structural models for countering the coverage of terrorist activities in media space have been constructed. The context of the model of counteraction to terrorist threats is defined. Based on the hierarchical decomposition of the diagrams, the features of the structural organization of the counteraction process are investigated. The proposed model approach allowed to build a study, starting from the description of generalized structures to the analysis of the functioning of the system of counteracting the coverage of terrorists in the media space. The obtained models illustrate the mechanisms of formation of a system of links between state and public institutions targeted to deprive terrorism of its social base.

Analysis of the texts of Tuvan folklore is extremely important for the identification and preservation of cultural and ethnographic knowledge about the past of the Tuvan people. Electronic collections of works of Tuvan folklore are created for these purposes. The electronic collection "Tuvan heroic legends" contains digitized texts of works, their meta descriptions, reference books of narrators and language standards. Such information is well-structured and allows presentation in the form of a table "object-attribute", called a context. Context reflects the presence or absence of features characteristic of the studied works. Having a context, using mathematical methods, it is possible to solve various problems of machine learning with reference to the texts of the Tuvan heroic epic. The paper proposes a program for forming contexts for the electronic collection "Tuva heroic legends". It described in detail the basic functions of this program. This research was conducted with the support of the Russian Humanitarian Scientific Foundation, grant 16-34-1-01033.

The operation of finding the remainder of division is an arithmetic operation that plays a big role in number theory. The most important role this operation has in the design of devices using, modular arithmetic. Modular arithmetic has high parallelism and is often used with high-dimensional data to speed up computations. When working with modular arithmetic, data of large dimensions (about 128-512 bits) are often used. To find modular representation of data, effective way is needed to find the remainder from the division of multi-digit numbers by the corresponding set of moduli. The article explores the methods for constructing devices for finding the remainder of the division, for large dimensions of input data, in which the divisor p - is a constant and is known at the device design stage. The options for implementing such devices are investigated, their optimal parameters are determined, and the delay and area compared with the Verilog operation "%", both in the VLSI and in the FPGA synthesis.

When developing large information-measuring and control systems, special attention must be paid to the interaction of various blocks of the system with each other. For example, the structure of a software-hardware measuring channel consists of four consecutively connected elements: primary converter; analog-to-digital converter; software dynamic converter; digital to analog converter. To find the parameters of the measurement channel error, mathematical models were constructed for each of the blocks. Simulation modeling of the measuring channel was carried out. As the input signal, the first-order aperiodic link model is taken. To generate the interference signal, a random number generator with a noise level of 0.5 is used. The error for the measuring channel is found. The suggested mathematical model allows to find the tuning coefficients of the software of the measuring channel, which ensure the minimum information loss in the software-hardware measuring channel. The resulting model can be used in automatic control systems for the current identification of regulator settings.

At the moment one of the most advanced flexible methodologies IT project management is SCRUM technology. Its feature is the partition of the whole work on short iterations (sprints), each of which represents a cyclic process, repeated all the way through the product development process. This allows you to constantly monitor the emerging risks and minimize them effects. Each sprint starts with planning, which sets the pace of work and stimulates high performance. The key point of planning is predicting the level of focus of the team on the implementation of the tasks, the so-called focus factor. It is the ratio productivity to labor intensity. The paper presents the results of numerical experiments to identify the best methods for predicting this indicator. In their the production data of one of the project groups of the real commercial firm in the field of IT. Extrapolation forecasting methods with a sliding base on the previous actual results. At the same time, the width of the base one to seven previous periods), and the type of extrapolating function. Approximating polynomials of zero, first and second degree are considered. Attention has also been paid to the method of exponential smoothing and Bayesian approach to diagnosis and prediction. For the integral the quality of forecasting used the value of the root-mean-square relative performance error. According to the results of the experiments, three optimal variants are selected. The first is the forecast for the sliding arithmetic average of the actual focus-factors for 3-4 previous periods. In the second variant, again, the sliding the average of actual focus factors for 3-5 sprints, but not arithmetic, and geometric. The third method for predicting is the product theoretical focus factor on the actual. We use the geometric mean it per the 1-2 sprints. In the mean square norm for both methods, the prediction error is the same, about 5.8%. If we estimate it not by the mean square metric, but by maximum deviation, then the latter option is slightly better. Results are intended to clarify the intuitive planning of sprints when performing real projects.
