  • 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. Other methods are based on piezo-resistive sensors, pressure and airflow sensors, and airways resistance sensors. The authors' developed device based on three-axis accelerometer is proposed. It recognizes episodes of apnea with sufficient accuracy for long-term monitoring. The algorithm of the accelerometer data processing is described. In order to minimize noise impact on the useful signal it is necessary to transform the three-dimensional cloud of accelerometer data into a flat sector. Then the relation of gravity vector deviation angle and the nominal position in time is determined. This presented device due to its ability to transmit data via Bluetooth technology, after appropriate software development for mobile phone and the receiving terminal of medical professional, will be able to organize a simple ergonomic long-term remote monitoring of respiratory activity.

  • Dynamical choice of the order in the multirate adaptive filter

    The new way of multirate adaptation is considered. The main idea is the filter ability to change the order of the filter automaticaly by the appropriate algorithm.
    The power on the filter output consists of two components. The first one is caused by the impulse response truncation, and the other is caused by weights fluctuations in the adaptive processing. More weights contribute more noise in adaptive signal processing. The result of adaptive procedure is the choice of the best filter orders in every channel of the multi-channel structure.
    The main interest of this investigation is in the adaptation of the multirate adaptive filter with the flexible structural self-organization.
    Due to the use of dynamical order adaptation procedure in the subbands, it is possible to reduce the total amount of the computational operations without quality reducing. Beside it, decreasing of the filter orders in the separate channel promotes considerable increase of the signal-to-noise ratio in the output signal. These statements are approved by experiments with the equalization problem.
    Different results of the computer modeling are supplied with proper comments.
