  • Evaluation of transportation risks of non-standard cargoes on the example materials handling equipment

    The problem of reduction of costs associated with the performance of work in remote areas, which should be delivered to special funds for the execution of works, is relevant in view of the ever-increasing one-hundred-imosti special technique, bulkiness of many of its types and problem-sti move its modern road and other routes. Hod them from directions to reduce these losses is to find the best options to transfer credits on the basis of building a formal model describing the process of moving. It is this problem, and in is devoted to this work. In the formalized problem of minimizing the risks caused by losses and costs associated with the delivery of the Ad Hoc technology to remote-ly located sites working on co-toryh can be carried out construction, installation, repair, supply of-malarial and other works. The classification of the problems associated with the movement of special equipment and, above all, Conveyor as the most cumbersome and capacious types of such equipment. We write the expression for the losses and expenses associated with the pro-cess of transportation. These expressions include four of subsidiary function, which in turn depend on a number of constants and pro-simplest functions. The first of these auxiliary functions Inves-vestigated for the most important field of application of the developed model - for the construction sector. An analytical expression for the function.

  • A formalized risk assessment model of operation materials handling equipment

    The problem of reducing the costs associated with the performance of work at the construction site, is relevant in view of the ever increasing cost of special equipment and materials used in con-ment, the tightening competition in the construction market. One of the ways to reduce these losses is the search of an optimal variants of the organization of the construction process, in particular for road construction equipment and above all Conveyor (TCP). That this problem is devoted to this work. In the formalized problem of minimizing the losses and costs associated with the delivery with the implementation of various support accompanying PTS use processes. Accounted for a large set of facts which could have a negative impact on the process uses the TCP-tion. These expressions include seven support functions, which in turn depends on a number of constants and simple functions. We studied two of the seven auxiliary functions on demand-built bathrooms in models obtained analytical expressions for calculating the values ​​of these functions.

    Keywords: lifting the vehicle, a mathematical model, the construction area, risks, losses and expenses, minimization, auxiliary functions, the evaluation of the model parameters.

  • Using of pseudo-random sequences in quantum communication systems

    Coding of information using of pseudo-random sequences  in quantum communication systems providing an operation with a low probability of single-photons detection is proposed. The results of statistical modeling of information extraction from the bit stream, received at different specified probability of detection based on the correlation properties of the M-sequences are demonstrated. It's demonstrated that the peak value of cross-correlation function for the M-sequence of 255 bits is on the average more than 2 times higher  than the level of side lobes at the probability of single-photons detection 20%.

    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.

  • On about the features of UAV control systems with flapping wing

    In the article a number of approaches to a flapping wing pilotless vehicle control system synthesis are analyzed. Referred type of pilotless vehicles is possessed of a number of advantages compared to the traditional schemes, but requires a special approach to control system creation because of strong nonlinearity and multicoupling of a controlling object mathematical model. As a result of a control system synthesis approaches analysis a synergetic approach was marked out as the most adequate for the mentioned above type of controlling objects. An idea of prognostics application for the goal of reaching of adaptive control is also set forth. In this case parameters of an object of control and parameters of ambient both are to be forecasted whereby an adaptive behavior of an object of control is expected to be achieved.
