Russian Crime of the Past Decade: Is the Time of Illusions Over?

The purpose of the study is by analyzing the state and dynamics of crime in Russia over the past decade (2010-2020): 1) to identify the factors that influenced the criminal activity of the Russian population during this period; 2) determine the main directions of the then implemented state criminal policy; 3) assess its effectiveness. Research methods: method of summary and grouping of statistical observation materials, analysis of absolute and relative values (structure, intensity and dynamics), analysis of series of dynamics. The results of the study indicate that, since 2015, there has been a progressive increase in crime in Russia, due to unfavorable trends in the development of the socio-economic sphere. During this period, there was also a significant discrepancy between the data of official crime statistics and the real situation in the field of crime. This discrepancy was due to large-scale transformation processes taking place in the sphere of the state’s criminal policy. Accordingly, the decrease in the amount and level of official crime in Russia in 2016-2018 was a consequence of these processes, while the real crime continued to grow all these three years. However, the sharp increase in crimes against property committed through the use of information and communication technologies, which began in Russia several years ago, ultimately could not but be reflected in the data of official crime statistics – in the past two years, an increase in both the amount and the level of crime has been recorded in the state. Russian law enforcement agencies have so far shown their unwillingness to offer serious resistance to digital crime. Russian law enforcement agencies have so far demonstrated their unwillingness to offer serious resistance to digital crime. The situation is significantly complicated by the fact that a significant part of crimes in the sphere of information and communication technologies is committed by inmates of Russian prisons. This means that today, in addition to a strong external influence from the criminal environment, the country’s law enforcement system is also experiencing a powerful endogenous influence from the criminals who are already serving their sentences in prisons

Study of the stress-strain state of a flexible tubular element of the working body of a tillage machine

The designs of the working bodies of tillage and sowing machines are subject to requirements to ensure optimal agrotechnical requirements and minimize energy costs. This can be achieved by creating machines with controlled working bodies that are able to accurately comply with agrotechnical requirements and respond in a timely manner to changing external conditions. Known are designs of the working bodies of tillage machines, in which a flexible tubular element (manometric tubular spring) is used as a stand. When applying variable pressure to the cavity of the tubular element, its end performs a reciprocating motion, which improves the quality of tillage. The paper presents the results of a study of the stress-strain state of the tubular element of the coulter using the ANSYS software package. The authors built a grid model of a tubular element, determined the horizontal component of the force of the soil impact on the coulter, at which stability loss is observed, and studied the influence of the geometric characteristics of the tubular element—the shape of the section, the opening angle, and the bending radius—on the critical force value. Tubular elements with a section variable in length were also investigated and their effectiveness was shown

Cavity-QED simulation of a quantum metamaterial with tunable disorder

We explore experimentally a quantum metamaterial based on a superconducting chip with 25 frequency-tunable transmon qubits coupled to a common coplanar resonator. The collective bright and dark modes are probed via the microwave response, i.e., by measuring the transmission amplitude of an external microwave signal. All qubits have individual control and readout lines. Their frequency tunability allows to change the number N of resonantly coupled qubits and also to introduce a disorder in their excitation frequencies with preassigned distributions. While increasing N, we demonstrate the expected N$^{1/2}$ scaling law for the energy gap (Rabi splitting) between bright modes around the cavity frequency. By introducing a controllable disorder and averaging the transmission amplitude over a large number of realizations, we demonstrate a decay of mesoscopic fluctuations which mimics an approach towards the thermodynamic limit. The collective bright states survive in the presence of disorder when the strength of individual qubit coupling to the cavity dominates over the disorder strength

ARAHAN PENATAAN RUANG JALAN MAGELANG - YOGYAKARTA KAJIAN SETTING ELEMEN FISIK DAN AKTIVITAS

The condition of the road of Magelang - Yogyakarta that based on its function is the arterial route, is one of the factors that cause the area around the arterial lane into the area with a rapid growth and development character, especially in commercial terms. These conditions required a study that aims to determine the specific characteristics of the physical settings and activities setting of the area around the arterial street and the factors that influence it so that the results can be used as consideration material in the settlement and development of the area around the arterial street. Research in the area of Jalan Magelang � Yogyakarta uses rationalistic qualitative approach/paradigm with emphasis on the understanding of the problems in the research area based on realistic conditions, then formulate the problem which is based on theories that relate to the context of the research on selected locations of Magelang - Yogyakarta km. 0 - km. 6, Sleman, Yogyakarta street space. The results will answer the purpose of the research and produce conclusions which include the existing characteristics of the physical settings and activities setting of the area, and also the interplay between the physical settings and activities setting of the area where the existing condition of the physical elements in the area cannot optimally and ideally accommodate and support the activities in it, both the dominant commercial functions and daily activities of society in general, and the factors that influence these condition. Based on these considerations, the parameters of design guidelines and development plans of research area can be formulated. The output produced in this research is the design guidelines, and guidelines to manage the setting of the physical elements of Magelang - Yogyakarta km. 0 - km.6 street space, which can emerge the existence of a commercial character as a growth and development potential of the region

Simulation of a tubular cultivator rack of tillage machines under static and dynamic loads

Curved tubes of non-circular cross section are widely used in various fields of technology. The change in the planned operating modes of various technological processes is associated with the wear of the executing mechanisms, which is caused by unstable frequencies and amplitudes of oscillations. Thus, the issue of determining the oscillation parameters of these elements becomes more significant. The technique and results of tests for stresses, displacements and frequencies of natural oscillations of a tubular cultivator tine made in the form of a curved tube of various sections (mainly flat-oval with an inverse ratio of semiaxes) in the ANSYS software package are presented, the maximum allowable loads and the effect of a rigid tip on oscillation frequencies are determined
