Identification of railway vehicles is relevant for the conversion from automatic control systems with manual data input to automatic modeling environment of train and vehicle. The most effective and economic inventory number recognition is optical recognition. But there is question about veracity in such technology. This paper represent the qualitatively new approach for optical recognition based on building integral robust constructive features of vehicles and allowed to significantly increase level of recognition veracity. Proposed technique investigated in introduction subject of automatic vehicle number recognition system (ARNV). Computational experiments demonstrated relevance of proposed technique for using in optical recognition of vehicle numbers.

The core of any economy is the production, creation of economic output. No production can not be use. That's enterprises produce products that perform work and services, ie provide the basis for consumption and increase national wealth. Matter how well the company what their financial condition, depends on the health of the economy and the industrial might of the state. If present schematically the entire system of economic governance in the country in the form of a pyramid, its base are businesses. State, regional, departmental management can be considered in relation to the processes occurring at the level of the enterprise, just as the add-on, secondary phenomena.

To evaluate the effectiveness of remediation of soils contaminated with petroleum or petroleum products, it is advisable to use the method for determining the integral indicator of biological condition (IPBS) of the soil, calculated on the most informative biological indicators. If, before reclaiming the difference between the IPBS contaminated and uncontaminated (background) soil is less than 10%, it is advisable not to carry out remediation. If the value of IPBS re-cultivated soil and uncontaminated soil IPBS value differ by less than 10%, then reclamation carried out efficiently.

"The aim of this work - analysis of mechanisms of formation of various types of sales management systems, which are used by the Russian entrepreneurial companies. In carrying out this study tested the accuracy of the following hypotheses:
Hypothesis 1: Managers and owners of business enterprises of small and medium-sized understand the critical importance of effective functioning of the sales department of the company to achieve market success.
Hypothesis 2: Managers and owners of business enterprises of small and medium-sized most significant function of sales management consider the function of monitoring the activities of sales personnel.
Hypothesis 3: Managers and owners of small entrepreneurial companies and medium size often organize sales management functions on the basis of the existing market and examples of their experience.
Hypothesis 4: Managers and owners of business enterprises of small and medium-sized believe that one of the main goals of training sessions held in - getting sales staff about how he should conduct their work in the market."
Keywords: The entrepreneurial companies, the effectiveness of the sales department, the function of control, the function of sales management, training.
A method of expanding the bandwidth and improve the performance of the differential voltage divider – attenuator (AT), which have parasitic capacitance on the outputs C01, C02. Wide range of transmission of the AT provided by introducing a compensation circuit C01, C02, which is achieving data quality indicators. Simulation results of desired are shown.

The monitoring system of process of stabilization of levels of metal on continuous moulding of preparations machine, constructed useing the observer of a condition is considered. The developed nonlinear observer allows to increase the accuracy of an assessment of levels of the melted metal in the ladle with steel ,industrial ladle and crystallizers, and also makes continuous diagnostics of a condition of glasses of latches. The analysis made on the basis of linearized model, showed the observability and controllability of system on all interval of pouring.
Keywords: Machine of continuous moulding preparations,the controllability, the observability, the observer of a condition, the level of metal
