    Keywords: centrifugal oil filter, technology maintenance, lubrication system

  • Methodology to evaluate the feasibility and effectiveness of remediation of soils contaminated by oil and oil products, the biological indicators

    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.

    Keywords: pollution, soil, oil, oil products, remediation soil biological properties of the soil, the effectiveness of remediation

  • Features of the production work on lifting and leveling in a cramped building

    The article describes the experience of the unique complex of works to improve the operational reliability of the emergency office buildings located in a cramped building, whose main task was to eliminate excessive rolls with hydraulic jacks and ensure the continued trouble-free operation. Highlighted the key features of the design and technology solutions for the simultaneous lifting and leveling of several buildings with different design decisions.

    Keywords: adjustable foundation, electro-hydraulic flat jacks, cramped building, lifting and leveling, operational reliability.

  • Kinematic investigation of the mechanism of the ladle turning of the rope excavator

    The research devoted to the kinematic mechanism for turning rope of ladle excavator, in the article considered the part of the trajectory of the work process: this process make the turning of the grip relatively to the arrow with the same time turning ladle relatively to the grip. The ladle turning is made because of additional kinematic connection between the ladle and grip and / jr the arrow and implementing internal forces due to the mutual position of the corresponding arrow and grip.

    Keywords: the rope excavator, the ladle turning, kinematics, the analitical investigation

  • The impact of point source on an anisotropic poroelastic plane

    The dynamic problem  of an anisotropic poroelastic plane under an influence of point source in the steady-state oscillation mode is studied. An analytical solution of the problem as a single integrals over a finite interval is given. Numerical experiments on the construction of solutions are made and the results are compared with the known classical solutions.

    Keywords: poroelasticity, vibrations, anisotropy

  • The development of toolkit of cognitive modelling for research of difficult systems

    In the article the approach to modelling and the analysis of functioning of difficult systems based on indistinct cognitive maps is described. The theoretical part of the article is devoted description of modern family cognitive maps, the short characteristic and the analysis of following groups is given: Cognitive Maps, Fuzzy Cognitive Maps, Fuzzy Cognitive Maps by Silov, Rules Based Fuzzy Cognitive Maps, Generalized Rules Based Fuzzy Cognitive Maps, Relational Fuzzy Cognitive Maps, Neutrosophic Relational Maps, Dynamic cognitive networks. The concept of fuzzy way is entered for the development of mathematical toolkit and the model of fuzzy pulse process is offered. The practical component of the article is directed on the description of examples of the decision of separate problems of cognitive modelling with application of the device fuzzy directed graph of the 1st kind. The offered approach will allow to develop forecast scenarios of development of difficult system taking into account its reaction on external influences.

    Keywords: difficult system, fuzzy model, fuzzy cognitive map, fuzzy way

  • Agent based modeling of the social conflict: Osetino-Ingushskiy conflict in the area of village Tarskoe

    Agent based model was developed. This model is showing processes of conflict, which is happening on the area of village Tarskoe. Conflict, which is called Osetino-Ingushskiy started in October 1992, and was not stabilized till today.

    Keywords: agent base modeling, agent-based model, NetLogo

  • Regularities of zinc transformation process in ordinary chernozem in the presence of different anions

    The influence of attendant anions on the transformation of zinc compounds in the soil was studied in a model experiment. The differences in the number of mobile forms of recoverable zinc in the soil, depending on its dose and form of addition were defined. Influence of associated anions on the content of metals mobile forms in the soil decreases in the order: PO42¯≈ Cl¯ > NO3¯ > SO42¯> СН3СОО¯> О¯. Transformation of zinc compounds during 2-year period after the receipt of the metal in the soil has been studied.  There is no soil stabilization in ratio form for two years studying, indicating the low speeds transformation of metal compounds with soil components. Transformation of Zn in soil depends on the attendant anion, metal concentration in soil and time interaction with the solid phase of soils. The transformation process of metal adsorbed the soil goes toward to decrease of Zn mobility.

    Keywords: transformation, ordinary chernozem, zinc, attendant anion

  • The adaptive suppression of motion artifacts at horse ECG recording

    The article deals with interference suppression algorithms that arise in the ECG signal by moving of the electrodes due to the motion of the object. It is proposed to use an adaptive filter, which reference signal is provided by the data triaxial accelerometer.

  • The motor vehicle model for integrated navigation systems

    Modern ultra-tight integration structure of strapdown inertial systems and global positioning system, based on the linearization of the navigation measurements and linearization of measurement errors models, are not not applicable for motor vehicles navigation. The adequate standard stochastic model of the vehicle perturbed motion has been synthesized. The model can be used for the integration Kalman filter. Such correlations can result in poor real-time estimation accuracy of navigation parameters of motor vehicle.

  • The loosely coupled algorithm of integrated INS-GPS navigation system of the vehicle

    The existing approaches to the integration of relatively cheap strapdown inertial navigation system (SINS) based on MEMS-based technology and satellite navigation systems (SNS) are ineffective in relation to motor vehicles. We consider the iterative algorithm for the loosely coupled mode of integration of heterogeneous navigation systems do not intend to use the optimal estimation. The solution is obtained on the basis of the fully nonlinear model of the navigation system of the vehicle and the, therefore, is valid for arbitrary and unknown in advance nature of his movements, and, in the most general assumptions about the level of disturbances acting upon him.
