Dialectics of Efficient Change Management in the Regional Social Systems

The research has placed emphasis on the role of the social infrastructure sectors, providing social services, which facilitate human potential development in a modern state. Theoretical positions of the scientist considering the nature of social benefits and necessity of the government support for the social sphere has been summarized in the article. The state of the Russian social infrastructure sectors has been considered and the analysis of their performance compared to these of the social infrastructure sectors in other countries has been conducted in the research work. Taking into consideration the performance ratings of the effectiveness of the national education systems, the countries around the world concerning the effectiveness of the health system, the countries around the world concerning the social development level in 2014, the authors have proposed the conceptual approach that makes it possible to consider the correlation and interrelation of the level of the government financing of the social sphere and the dynamics of the contribution of social infrastructure sectors in the development of the human capital, ensuring the gross domestic product increase. The necessity of making innovative changes in the socio-economic systems of the social infrastructure sectors, to improve their performance, taking into account the results obtained, in the first place, in health care, has been wellgrounded and theoretical approaches to the changes management in the socio-economic systems has been studied in the article. The theoretical approaches to the changes management in the socio-economic systems have been studied by the authors. Based on the conducted studies and the formed theoretical basis for improving the level of changes management in open socio-economic systems, for the purpose of development of the theoretical and methodological approaches to changes management as applied to health care sphere, optimization model of management of health care organizations by way of ranking of manageable and unmanageable changes has been proposed. The possibility of using management optimization by way of ranking of manageable and unmanageable changes in the health care management at different levels has been confirmed with high-performance indicators at the micro-, meso- and macro levels in the sector, by the example of implementation of the national project “Health” and innovative organizational changes facilitating the return to work of patients of the working age, which are involved in the gross domestic product formation in the city of Yekaterinburg.The article has been prepared with the support of the Russian Science Foundation grant No. 14-18-00456 “Support of geoecosocioeconomic approach to development of strategic nature resources capacity of the low-studied northern territories within the investment project “Arctic — Central Asia”

The Klein-Gordon Equation and Differential Substitutions of the Form v=φ(u,ux,uy)v=\varphi(u,u_x,u_y)

We present the complete classification of equations of the form $u_{xy}=f(u,u_x,u_y)$ and the Klein-Gordon equations $v_{xy}=F(v)$ connected with one another by differential substitutions $v=\varphi(u,u_x,u_y)$ such that $\varphi_{u_x}\varphi_{u_y}\neq 0$ over the ring of complex-valued variables

On the relationship between the phases of 27-day total ozone and solar activity indices in different latitudinal zones

The dynamics of 27 day total ozone variations during and 11 year solar activity cycle at high and low latitudes was analyzed. The calculations were made using a specially worked out program permitting, besides the determination of the amplitudes and phases, the observation of the coherence of phases in any time interval. To characterize solar activity, solar radio-flux at 10.7 cm was used. The results of the calculation of total ozone phases difference and those of the index F(sub 10.7), as well as the amplitudes of the 27 day variations of these parameters are presented

Limitations of the classical phase-locked loop analysis

Nonlinear analysis of the classical phase-locked loop (PLL) is a challenging task. In classical engineering literature simplified mathematical models and simulation are widely used for its study. In this work the limitations of classical engineering phase-locked loop analysis are demonstrated, e.g., hidden oscillations, which can not be found by simulation, are discussed. It is shown that the use of simplified dynamical models and the application of simulation may lead to wrong conclusions concerning the operability of PLL-based circuits

A short survey on nonlinear models of the classic Costas loop: rigorous derivation and limitations of the classic analysis

Rigorous nonlinear analysis of the physical model of Costas loop --- a classic phase-locked loop (PLL) based circuit for carrier recovery, is a challenging task. Thus for its analysis, simplified mathematical models and numerical simulation are widely used. In this work a short survey on nonlinear models of the BPSK Costas loop, used for pre-design and post-design analysis, is presented. Their rigorous derivation and limitations of classic analysis are discussed. It is shown that the use of simplified mathematical models, and the application of non rigorous methods of analysis (e.g., simulation and linearization) may lead to wrong conclusions concerning the performance of the Costas loop physical model.Comment: Accepted to American Control Conference (ACC) 2015 (Chicago, USA
