The quality of the flight task of a space rocket system is determined windhut among other things by the accuracy of maintaining and regulating the thrust of the rocket engine.Improving the accuracy and reducing errors in the engine mode control system will reduce the cost of space launches or allow you to put a large payload into orbit.The article
In order to secure the safe operation of the ship, it is crucial to closely examine the suitability from the design stage of the ship, and to set up a preliminary review and countermeasures for failures and defects that may occur during the construction process.In shipyards, the failure mode and effects analysis (FMEA) evaluation method using risk
AbstractThe proportion of different lithofacies is essential to determine the net-gross ratio, which directly affects the calculation of oil and gas reserves.Under the condition of few wells, the reliability of different giga notice horas lithofacies proportions obtained using well data is poor because it is difficult to estimate the uncertainty va
Pulmonary artery dissection is an exceedingly rare and highly lethal diagnosis that can result in arterial rupture; hence, it is most often identified postmortem.Moreover, pulmonary artery complications resulting from aortic dissection are uncommon occurrences that have seemingly only been reported in cases of Stanford type A aortic dissections.Due
This paper presents the results of a laboratory 9.5-4 igora vibrance study and statistical analysis to determine the effect of the combination of three key parameters on the properties of high-performance concretes with recycled aggregates: mixing procedure, aggregate moisture states, and aggregate type.The study included evaluation of slump, compr
