A distortion generator equipped with a motor-activated movable flat baffle was installed just upstream of a rectangular plenum entrance to investigate the effects of inlet total pressure distortion on the stability and performance of an auxiliary power unit (APU).Experiments and numerical simulations on a direct connect scale inlet model of the APU
The object of research is the data augmentation method in text classification problems using machine learning methods.The method is considered on Lounge Chair with Cushion the example of sentiment analysis of visitor reviews of hotels.It is shown that datasets with insufficient volume or representativeness requires special methods for increasing th
Thermal protection systems (TPSs) are important components of reusable spacecraft, and their assembly quality has a crucial impact on flight safety.Owing to the complex assembly process and variable states of spacecraft thermal protection systems, assembly parameters may vary under different assembly states.Therefore, to obtain assembly parameters
