  • The Correlation Analysis of Vocal Speech as a Nonstationary Random Process

    Vocal speech is a random process. Taking into account the fact that the main characteristics of a singing voice vary with time, in the article vocal speech is studied as an acoustic nonstationary random process. To describe this process we should calculate one of its informative parameters – the autocorrelation function. The findings show that there are some differences between the autocorrelation functions for professional and nonprofessional singers. This helps to make a quantitative assessment of a singer’s professionalism which, alongside with a vocal teacher’s subjective assessment, can present an objective view on a singer’s voice and provide a good basis for optimization of academic voice training. Moreover a teacher does not have to be technically educated because this quantitative assessment is presented in diagrams which are quite easy to assess visually. It is especially important to consider when we use the given voice assessing method in music schools, colleges and universities.

  • Complementarily - Adaptive use tools of intergovernmental relations for the purpose of leveling the socio-economic development of regions

    The current system of intergovernmental fiscal relations , the trends of its development in Russia , including the alignment process , aimed at smoothing the territorial differentiation of socio- economic development of regions. The main task of any state , regardless of the device is to smooth regional disparities through a reallocation of financial resources. In this case, the stability of intergovernmental fiscal relations between the federal center and the subjects of the federation is largely determined by well-functioning system of fiscal federalism. Currently, the budget process is characterized by serious contradictions that arise during the development phase as well as on the stages of implementation of management decisions. Global experience demonstrates the lack of an optimal model of intergovernmental relations . Vertical alignment is the process of achieving a balance between the commitment of each level of government expenditure with the potential of its revenue sources . The tools include the vertical alignment of the fixing of taxes for a certain level , subventions and subsidies, regulating the distribution of income. The horizontal alignment is aimed at providing a unified standard level of consumption of public services to the residents of different regions of the country. With reference to the Russian economic space horizontal alignment problems are quite complex , since there are strong differences in socio-economic development of the regions due to climatic and historical factors .

  • Local Atomic and Electronic Structure of the Fe dopants in AlN:Fe Nanorods

    Fe-doped AlN nanorods were studied by means of x-ray absorption spectroscopy above the Fe K- and L2,3- edges. Theoretical simulations of the x-ray absorption spectra show that Fe atoms mainly substitute Al. A minor fraction of Fe interstitials or Fe-Al-N ternary alloy can be identified as well. Bader’s AIM analysis predicts that neutral substitutional FeAl defect is in 2+ charge state, though Al in pure AlN is in 3+ charge state.  Fe L2,3 absorption spectra and photoluminescence data indicate the coexistence of Fe2+/Fe3+ in AlN:Fe nanorods so different charge states of substitutional FeAl should co-exist.

  • Long-term monitoring of human respiratory activity

    This article reviews systems of respiratory activity registration in relation to sports medicine. Attention is devoted to the use of miniature accelerometers that record the movement of the chest, as the optimal method for the diagnosis of the respiratory parameters.

  • The computational model of radial plain bearing with increased load capacity, working on micropolar lubricantgiven its viscosity characteristics of the pressure

    As is known, currently in a model gidrodinaimcheskoy sliding bearing lubricant widely used micropolar lubrication. A major shortcoming of existing working models of bearings running on micropolar lubricant is that this does not take into account the dependence of viscosity characteristics of the micropolar lubricant on the pressure. Naturally, there is a need not only into account the dependence of viscosity characteristics of the pressure in the development of an analytical method for predicting the optimal carrying capacity characteristics inherent MICROPOLAR grease, but also predict the optimal profile of the reference surface of the radial bearing. [1-3 ]Solving this problem is devoted to this work.

  • The computational model thrust bearing with high load-bearing capacity, working on non-Newtonian lubricants with tailored support surface

    The ability to choose the right anti-wear additives [1-6 ] allows you to create lubricants , which are thin layers have different properties than in large volumes. It is commonly assumed that the additives are functioning only in the zone boundary lubrication and are outside the scope of the hydrodynamic theory of lubrication . However, the beneficial effect of additives as indicated in many studies [1-5 ] we have in the " thin layer" of hydrodynamic lubrication .As is well known , lubrication bearings operate on different types of lubricants which are composed of base oil and additive compositions that provide the required functional properties of the oil . Additives polymers with high molecular weight oils impart viscoelastic properties . Analysis of existing studies [ 7-9] on the calculation of bearings running on a viscoelastic lubricant , shows that they do not take into account the dependence of the viscosity and shear modulus of the pressure and temperature, and mode of friction is assumed laminar. It is known [ 10 ] , high-speed bearings operating in turbulent friction , higher pressure and higher temperature, and so the development of methods for calculating the bearings running on a viscoelastic lubricant requires consideration of the above factors.In connection with the above written shall first develop the computational model of thrust bearings running on micropolar lubricant with the viscosity characteristics of the lubricant on the pressure in contrast to the existing theoretical models do not take into account these dependencies (task 1).And then consider the calculation model of extra load -bearing capacity , working on a viscoelastic lubricant for the dependence of its characteristics on the pressure (objective 2).
