Abstract: Изобретение относится к трубопроводному транспорту и может быть использовано при строительстве трубопроводов для подавления их вибрации. Устройство подавления вибрации содержит устанавливаемое на трубопроводе неподвижное звено и шарнирно соединенные с ним подвижные звенья, вместе представляющие собой установленное на внешней поверхности трубопровода многозвенное полое подвижное сочленение. Все звенья через радиально расположенные на них отверстия стянуты стальными стержнями, изменяя тем самым жесткость трубопровода. За счет количества подвижных звеньев, ограниченного длиной участка трубопровода, подверженного вибрации, изменяют весовые, а следовательно и частотные, характеристики трубопровода, что в сумме приводит к подавлению вибрации трубопровода. Технический результат: уменьшение уровней вибрации в поперечном сечении трубопровода, а за счет изменения частотных характеристик, вызванных увеличением массы, возможно снижение уровня вибрации и в продольном направлении. Устройство может быть использовано на объектах со сложной трубопроводной обвязкой. Монтаж устройства может быть выполнен без дополнительной доработки трубопровода и строительства дополнительных опор. 2 ил.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to maxillofacial surgery, and discloses a method for determining the adsorption capacity of granular osteoconductive osteoplastic material (GOOM). The method is characterized by the fact that dust and air bubbles are removed from the GOOM by the degassing method, which includes the stages of passive and active degassing using physical and chemical methods, namely heating in a thermostat in physiological solution and sonication using a citric acid solution. Next, the difference between the initial liquid volume and the liquid volume after passive degassing is calculated, as well as the difference between the liquid volumes before and after active degassing, then the indicated values are summed up, the resulting sum calculated for 1 ml of GOOM is the adsorption capacity of granular osteoconductive material. The method is aimed at optimizing the reparative regeneration of bone tissue by the method for directed bone regeneration. The use of the method for directed bone regeneration to eliminate a bone defect implies the use of bone-grafting materials as a matrix for reconstruction with external-internal surfaces and spaces available for the adsorption of bone growth factors. 
     EFFECT: method allows, due to the proposed degassing method, increasing the adsorption capacity of the original GOOM, optimizing the biotransformation of the osteoplastic material placed in the recipient bed into native bone, which will optimize the treatment time, avoid postoperative complications and repeated surgical interventions.

In the method of short-term adaptive prediction of interference levels in the decameter range with a variable duration of the history at each of the analyzed frequencies, the interference levels are measured at different lengths of the control intervals. For each duration of the control interval, both the averaged interference values ​​and the sum of the average interference levels and their standard deviations are calculated, based on the results of which these parameters are predicted for small time intervals. After that, the magnitude of the prediction error is estimated and, based on the results of the assessment, the prediction parameter, the duration of the control interval and the adaptive smoothing coefficient for each frequency are selected, which provide the minimum mean square prediction error. Further, with the help of additional measurements and the method of exponential smoothing of interference levels, prediction is carried out with the prediction parameter selected for each frequency, the history period and the adaptive smoothing coefficient. 
     EFFECT: increasing the reliability of forecasting for some time ahead.
