На основе анализа требований по надежности к электрорадиоизделиям устройств сбора данных в телеметрических системах проведена расчетная оценка показателей надежности элементным методом с использованием автоматизированной системы расчета надежности. Исследованы дополнительные возможности автоматизированной системы: разбиение исходных данных на независимые проекты расчета. Расчетная оценка выполнена для экспоненциального закона распределения времени между отказами, стационарного потока отказов и предположения, что отказы являются событиями случайными и независимыми. Based on an analysis of the reliability requirements for electrical products of data acquisition devices in telemetry systems, a reliability rating is calculated in accordance by the elemental method using an automated reliability calculation system. The additional capabilities of the automated system are investigated: splitting the source data into independent calculation projects. A calculation estimate is made for the exponential law of the distribution of time between failures, the stationary flow of failures, and the assumption that failures are random and independent events.

The paper considers goals and problems of information-management system interoperability support of the regional situational centers. Three types of the information system components interoperability support problem at technological, semantic and organizational interaction level are assigned. Problem-solving directions of information system interoperability support of regional situational centers based on application of multi-agent technologies and ontologies are proposed.

Произведена оценка влияния флуктуационных стационарных мультипликативных помех, действующих одновременного с аддитивными помехами, на точность измерения неэнергетических параметров информационных сигналов. Показано, что мультипликативная помеха низкого уровня оказывает более сильное влияние на точность измерения времени прихода, чем на точность измерения частоты полезного сигнала. Осуществлена количественная оценка влияния мультипликативной помехи на точность измерения неэнергетических параметров полезного сигнала. The influence of fluctuating stationary multiplicative interference acting simultaneously with additive interference on the accuracy of measurement of non-energy parameters of information signals is estimated. It is shown that low-level multiplicative interference has a stronger effect on the accuracy of the arrival time measurement than on the accuracy of the useful signal frequency measurement. A quantitative assessment of the effect of multiplicative interference on the accuracy of measurement of non-energy parameters of the useful signal is carried out.

For the first time, the problem of bending a circular plate under the action of the harmonic distribution of the intensity of a transverse load was solved. For the first time, the solution was constructed by lowering the order of the differential operator in the plate deflections equation from fourth to second order, which made it possible to divide the solution of the problem into two stages. At the first stage, the boundary conditions for the equality to zero of vertical displacements of the plate and the smoothness of its deflections in the center were satisfied. At the second stage, either the edge pinching condition or zero bending moment condition on the edge of the plate was satisfied.
