  • To questions of construction of integrated operators with осциллирующими in factors in space L2(Bn)

    Article is devoted multidimensional integrated operators with homogeneous kernels and oscillating in factors of a special kind. The operators representing the sum of the composed are studied: the initial integrated operator with a homogeneous kernel, the operator with осциллирующим in factor and a homogeneous kernel. For the given operators the concept of a symbol, of which terms is defined the criterion neterovosti and the formula of calculation of an index is received. The task in view decision is based on a reduction of the multidimensional integrated equation to infinite diagonal system of the one-dimensional equations.

  • Improving the accuracy of extrinsic camera parameters calibration

    The model of the ideal video camera is described, the form of the intrinsic and extrinsic camera parameters is showed. The relations between coordinates of a point in the world coordinate system with coordinates of this point on the image plane are given. The problem of finding extrinsic camera parameters from corresponded world and image points is posed. The error of found extrinsic parameters is estimated by simulation for several configurations of calibration objects consisting of a variable number of points on different distances from the camera and with different angles between them. On the basis of simulation results recommendations are given for the choice of the calibration object in order to improve the accuracy of the extrinsic camera parameters. The best results may be obtained with a configuration consisting of points that have a large angular distance between them and are posed on different distance from camera.

  • Modern socio-ecological and economic efficiency and environmental performance of production systems

    Analyses the cost-effectiveness of investments in environmental protection measures and methods for identifying them. Capital investment in manufacturing ensures increase of profits and the effect of environmental costs is expressed in the form of avoided losses caused by pollution. Through extensive and wasteful environmental management regime many industrial actors enterprises-users of irreparable environmental damage to the Habitat of the region. Of possible solutions to the problem of environmental pollution, it is the ekorestrukturizacia of production and its ecological modernization of environmental pollution requires improvement of existing models for the protection of the environment, optimizing the choice of the most effective measures, radical improvement of socio-ecological and economic climate in the regions. Ekorestrukturizacia national complex branches of industrial and territorial systems and environmental improvements within sectors, forms the most important areas of the «new green industrial policy». Critical issues are handled at the macro level, are the determination of the level and structure of key macroeconomic indicators, including gross domestic product, gross national product. The regional nature conservation is not only and not so much at the enterprises and in industry, where these activities are carried out on the whole of the territory covered by their action. Environmental issues should be based on the economic mechanism of nature protection measures not inconsistent with socio-economic objectives of industrial and territorial systems in General.
