  • Research of algorithms vibroacoustic diagnostics vehicles

    With the growing fleet's increasingly acute problem arises safety and reliability their exploitation as a result of this increase in productivity and accuracy of their technical diagnostics. Urgent task to further improve diagnosis for vehicles is to develop new methods and algorithms highlight the dominant component of the information in relation to a wide class of vehicles. The methods joint time-frequency and wavelet analysis. To isolate the dominant component of the information proposed to use the method of wavelet decomposition. Using vibro acoustic registration nodes vehicles funds allowed to receive signals carrying information about the defects of individual units of vehicles. The proposed decoding algorithms signals have high reliability, allow technical inspection, subsequent monitoring of the technical state of the vehicle. Using vibroacoustic registration of vehicles allowed nodes receive signals carry-ing information about the defects of individual units of vehicles.

  • The structure of data processing unit of multi-sensor system for concentration monitoring of heavy metal ions in aqueous media

    Common conceptions are given about multi-sensor systems. The structure of the data processing unit of multi-sensor system for concentration monitoring of heavy metals ions in aqueous media is described. Main stages of the data processing, – clustering and quantitative identification are introduced. The approach which presupposes use of artificial neural networks, – Kohonen networks and radial basis function networks, is designed. Such algorithmic architecture is implemented which allows to avoid significant computing resources expenses. The program for computer IBM PC in high-level language of application package MATLAB is written.

    Keywords: Multi-sensor systems, artificial neural networks, Kohonen networks, radial basis function networks, data processing, pattern recognition, environmental monitoring, heavy metals, ion-selective electrodes

  • Construction lending covenant

    Construction lending risks define a special operations procedure for lender. The most important measure to construction lending risk minimization are the covenants (information and financial). The information covenants are used for minimization the hidden information (pre-contractual opportunism), and financial covenants (positive and negative) – for minimization the hidden action (post-contractual opportunism). Institutionalization of covenants as a relevant control and supervision procedure allow to reduce information asymmetry and make the construction lending process less risky and more predictable for concerned parties (agent and principal).

    Keywords: real estate financing, default risk, construction loans, credit capacity, debt, financial covenant
