  • The Correlation Analysis of Ensemble Singing

    According to the signal theory vocal speech presents a non-stationary random process due to time variation of its main characteristics. A special emotional impact is gained during ensemble and choir performances. The article provides the correlation analysis results and the autocorrelation function of ensemble singing calculated, taking into account the non-stationary nature of acoustic signals. The studies have shown that there is a certain visual resemblance between correlation portraits of a non-professional student ensemble and a non-professional solo singer. At the same time the correlation portrait of student and professional co-performance tends to a professional singer correlation portrait. This helps to make a quantitative assessment of an ensemble’s professionalism which, alongside with a vocal teacher’s subjective assessment, can provide an objective view on singers’ voices condition to optimize the academic voice training process in an ensemble, which is important when using this voice assessing method in music schools, colleges and universities.

    Keywords: Vocal speech, acoustic signal, ensemble singing, choir performance, non-stationary random process, autocorrelation function, quantitative assessment

  • Some aspects of clustering economy Karelia

    An analysis of papers devoted to the clustering of the economy of the Republic of Karelia. Shows the need to focus on in this case the use of the unique geographical situation of the republic and its re – resource potential ( raw material and intellectual ). Taken into account that for more active clustering economy Karelia must development of its transport and energy infrastructure.

    Keywords: cluster, resource potential, transport and energy infrastructure, economy.

  • Russian language in Finland: Problems and Prospects

    We show that for specialists needed professional Russian-Finnish (Finnish-Russian) dictionaries that the promotion of Russian language teaching in Finland and Finnish as a foreign language is highly relevant, and its implementation should be multi-layered, designed for children, pupils, students Comrade, professionals of different specialties. 

    Keywords: education, promotion of the Russian language, Russian-Finnish dictionaries.

  • Some features of the mathematical description of forests production technological processes on the example of timber harvesting technology with the round logs production for wooden construction.

    A timber industry complex is a complex of technological processes linked with timber harvesting, wood transport and woodworking. For their optimization are used mathematical and economic methods. The brief overview of the application of mathematical modeling methods for the analysis and optimization of technological processes in the forestry sector is given in the article. Queuing theory is used for analysis of forestry process. For example harvesting technology with the round logs production for wooden construction is considered as G/G/1 queuing system. Well-developed models of queuing theory are recommended for analyzing of forestry process. Simulation models are recommended for deep analysis of forestry process.

  • 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.

  • GPR determination of electrical and physical properties of motor road and railway structural layers

    The paper studies the possibility of quantitative processing of the GPR data for determining the dielectric permittivity and conductivity of a medium (soil samples). Experimental studies are made using radargrams of soil samples with specified values of moisture and conductivity. New methods of quantitative processing of radargrams are proposed in this work to determine the dielectric permittivity and conductivity of soils. The methods were successfully tested on various sections of Russian railways net.
