  • Local logistic centers in urban environment

    The article presents the local type of logistic centers in urban environment as an essential part of freight network and its place in hierarchic logistic system of a country. Transport, compositional, ecologic and other aspects that have impact on spacial concept of local logistic centers are under examination. Thus generalized models of local logistic centers are put forward. They are developed by the authors with large volume of handled cargo, turnover capacity, and are space-saving. The main concepts of such models are following:  vertical development of storage volume due to construction of several floor and shelf storage levels with different ramps as well as provision of comfort one-way transport of minimum maneuvers and without crossing and conflicting traffic.

  • About the corporation questions

    The article explores the main types of organization of the corporation and management in Russia. The corporation is defined as a special organizational and economic form of business. There we identified problems, specific, prospects for the formation and development. It was investigated the features and structure of corporations , as a result of its membership of the integration processes . It was measured the economic and financial management aspects, which may be useful in the development and investment attractiveness of the corporation. The Corporation is a more complex business structure. Corporations  have certain rights, privileges, and liabilities beyond those of an individual. Doing business as a corporation may yield tax or financial benefits, but these can be offset by other considerations, such as increased licensing fees or decreased personal control. Corporations may be formed for profit or nonprofit purposes. The author gives the aspects of each formation.

  • Features of obtaining manganese dioxide by method thermolysis on the tantalum anode of condenser

    In the article obtaining of cathodic coating MnO2 on condenser porous tantalum anode was researched. It was ascertained that formation of crystalline defects from hydrated MnO2 on MnO2 coating obtaining by known technology is possible. Such formations disturb tantalum capacitor cathode integrity. To determine the reasons of the crystal defects formation conveyed simultaneous thermal analysis of Mn(NO3)2x4H2O and Mn(NO3)2x6H2O with an analysis of the flue gases by FTIR spectroscopy. Based on the analysis results a mechanism of manganese nitrate thermolysis was suggested and the cause of the crystal defects on the surface after the coating of manganese dioxide removed from the furnace was ascertained. It was established that the thermolysis process is followed by the formation of such manganese nitrate intermediates as manganese hydroxynitrate, manganese oxyhydroxide and its further oxidation to manganese dioxide. Because of secondary processes leaking on the MnO­2 cover manganese oxyhydroxide residual can react with water vapor and oxygen, that leads to the formation of crystalline defects. Such phenomenon has a negative impact on the chemical composition and integrity of the coating on the surface of the porous MnO2 tantalum capacitor anode. Also it has been found experimentally that manganese hydroxynitrate is formed from manganese nitrate in the form of microtubules on the porous tantalum vehicle surface.

  • Problem of determining the residual resource of technical condition of low pressure closed spillways waterworks

    Currently, more than 80% of water conveyance structures worked much the normative life. At the same time there is a simultaneous increase in the load on the aging waterworks, in the absence of the necessary skilled personnel and technical repair base will inevitably lead to an increase in the number of accidents due to operational reasons. Identification of factors that influence the condition of the facilities at the intersections , the search for methods of calculation and control of non-destructive methods to evaluate their work , life extension , etc. is of paramount importance at this stage. Residual life for the safe operation of water conveyance structures determined on the basis of system analysis with the development of the block diagram of a dynamic system having a number of subsystems. The main property that determines the life of the system , is the reliability of its elements , ie reliability and trouble-free operation for a certain period of operation. Dependability and reliability of the system as a whole is determined by the condition that each element of the system can be in one of two states - serviceable or failure.

  • Method of flexible time/frequency signal localization subsystem formation in adaptive filtering problems

    The new way of the organization of multistage time-frequency signal localization subsystems is considered. The investigations are constrained by finite impulse response class of digital circuits.
    The example illustrated the principle of agreement between pyramidal structure, formed of multistage including of any simple analysis/synthesis subsystem, and channel characteristics. This principle makes possible more precise localization of the input signal in separate frequency bands. The adaptive structure formation of the time/frequency transformation allows increasing of parameters characterizing the effectiveness of the subband adaptive filters (SAF).
    Application of the method of flexible time/frequency localization structure formation in the adaptive filtering problems allows significantly decreasing of processor loading by real-time realization of SAF.
    The other important advantage of the flexible SAF formation based on the least-mean-square algorithm lies in reducing of the adaptation period for the adaptive system.

  • Position predication of a dynamic agent tracked by quadrotor using neural networks

    Specialized robots are occupying a vast share of researches worldwide. In terms of aerial specialized robots, autonomy is the one of the major subjects that are being studied. As  known, flight autonomy is consisting of three parts: Mission planning, trajectory generation and path tracking. While it exists variety of local and global generation algorithm, UAV path planning is always associated with machine vision. This intellectual approach is solid because it can give a dual supervision link to the situation being surveyed. The operator has always the authority to step in and stop any unwanted action. The machine vision based algorithm has a huge disadvantage due to homogeneity and identity factors. This is because from distance object tend to look the same geometrically as well as color wise. In this paper we offer a solution to tackle the homogeneity problem between tracked agents which can cause local minimum problems. The UAV will forecast the next position of the tracked agent using Artificial Neural Networks. Position estimation is based on registered previous coefficient.
