    Gleissberg Cycle Dependence of Inner Zone Proton Flux by Emily J. Bregou, Mary K. Hudson, Brian T. Kress, Murong Qin, Richard S. Selesnick

    Published 2022-07-01
    “…Variation of inner belt protons is correlated with decreasing F10.7 maxima over the 40‐year period, serving as proxy for solar EUV input to Earth's atmosphere. Extending an earlier study (Qin et al., 2014; https://doi.org/10.1002/2014JA020300) of >70 MeV protons from 1980 – 2021 using the South Atlantic Anomaly (SAA) peak flux, and at fixed L = 1.3, a comparison is made between the >35, >70 and >140 MeV energy channels on POES. …”

    Formation of unmanned aircraft trajectory when flying around prohibited areas by A. A. Lobaty, A. Y. Bumai, A. M. Avsievich

    Published 2022-01-01
    “…The problem of analytical synthesis of the control acceleration of an unmanned aerial vehicle (UAV) is solved during its flight along a route passing along the boundaries of the forbidden zone of a given shape, along a given trajectory, which consists of subsequent segments located at the same height relative to the earth’s surface, in a given coordinate system. The optimal control synthesis problem is solved as an analytical definition of the optimal control of a linear non-stationary system based on the quadratic quality functional. …”
