Abstract: The corruption dynamics is analyzed by means of the lattice model which is similar to the three-dimensional Ising model. Agents placed at nodes of the corrupt network periodically choose to perform or not to perform the act of corruption at gain or loss while making decisions based on the process history. The gain value and its dynamics are defined by means of the Markov stochastic process modelling with parameters established in accordance with the influence of external and individual factors on the agent's gain. The model is formulated algorithmically and is studied by means of the computer simulation. Numerical results are obtained which demonstrate asymptotic behaviour of the corruption network under various conditions. [ABSTRACT FROM AUTHOR]

Abstract: BM@N (Baryonic Matter at Nuclotron) is an experiment at NICA (Nuclotron-based Ion Collider fAcility). The first physics runs with experimental data taking were carried out in 2018. Particle identification is necessary for the physical analysis of the matter produced in collision of the beam with the target. This paper describes identification algorithms based on the method and a variation of the distance method. The algorithms were tested on simulated data; the results on identification efficiency and the percentage of contamination for different particle types are presented. [ABSTRACT FROM AUTHOR]

Abstract: BM@N (Baryonic Matter at Nuclotron) is the first working experiment performed at the NICA accelerator complex. It is a fixed target experiment. To date, there have been seven runs of the experiment, most of which were technical. In 2018, the first run of the experimental facility with physics data acquisition took place. One of the prerequisites for physics analysis of experimental data is the existence of the primary vertex position estimation. This study describes the proposed algorithm for reconstruction of the primary vertex using the virtual planes method. The results of this algorithm for different targets, beams, and trigger conditions are presented. The sensitivity of the presented method is considered. [ABSTRACT FROM AUTHOR]

Abstract: Any large functioning system consists of equipment that needs to be repaired during its lifetime. The methods of mathematical programming are used to formalize the optimization problem of preventive equipment repair planning in this paper. The method is used to find the annual optimal plan of preventive equipment repair. The goal of such plan is the uniform distribution of repair works by the months. It is supposed, that the deviation from the standard plan of repair works can not be more than one month. An algorithm to find the optimal plan of repair works is provided. A numerical example is given. [ABSTRACT FROM AUTHOR]
