Quantum key distribution via satellites enables the technology to be applied at transcontinental scale; nevertheless, in contrast to fiber systems, using a free-space optical communication channel presents certain extra technological obstacles. The contribution of the acquisition, pointing and tracking system’s operation to the potential quantum bit error value is investigated in this research. The polarization extinction ratio measurements varying with the pointing mirror angular position are reported, based on these data, the upper limit of the quantum bit error is predicted for several types of satellite passages

The recursive (U|U+V) construction, a generalization of which includes polar codes, provides a powerful framework for building complex codes from simpler components. However, existing approaches predominantly rely on fixed or symmetric tree architectures, overlooking the critical impact of decomposition choice on code performance. This paper addresses the challenge of optimal tree decomposition selection by presenting a framework ...

This study introduces an innovative control approach for deploying multiple unmanned aerial vehicles (UAVs) to monitor an unknown food region. The proposed strategy is designed to optimally distribute UAVs across the food-afected area while cooperatively estimating the extent of inundation. To achieve this, an adaptive coverage controller is developed based on Centroidal Voronoi Tessellation (CVT), incorporating a novel ...

We present a methodology for calibrating doubly constrained gravity models. Three types of deterrence functions are examined: exponential, power, and combined. The latter includes two calibration parameters, whereas the others contain only one. The parameters are identified so that the model reproduces the observed trip length distribution with high accuracy. We test four optimization methods: ...
