A virtual flight test is the process of flying an aircraft model inside a wind tunnel in a manner that replicates free-flight.In this paper, a 3-DOF aircraft-manipulator system is proposed that can be used for longitudinal bonviv dynamics virtual flight tests.The system consists of a two rotational degrees-of-freedom manipulator arm with an aircraf
This paper proposes a time-varying amplitude frequency monitoring method based on sliding window FFT of sub-synchronous oscillation to identify the time-varying modal parameters of the oscillating signals on-line.Firstly, windowed interpolation methods are used to reduce the spectral leakage and fence effect, and decrease the FFT identification err
Abstract The tumor microenvironment (TME) is a highly intricate milieu, comprising a multitude of components, including immune cells and stromal cells, that exert a profound influence on tumor initiation and progression.Within the TME, angiogenesis is predominantly orchestrated by endothelial cells (ECs), which foster presonus eris e44 the prolifer
