TL;DR: The proposed beam management aims to achieve efficient beam tracking and NOMA-grouping-aware analog beamforming optimization to facilitate mmWave-NOMA transmissions by judiciously utilizing angular domain information (ADI).
Abstract: We consider a mission-driven multiple unmanned aerial vehicles (multi-UAVs) network with millimeter-wave (mmWave) transmissions, where a leader UAV (LUAV) communicates with a large number of follower UAVs (FUAVs) simultaneously via a uniform planar array with only a limited number of radio frequency chains. Since only a few orthogonal beams are available and mission-driven UAV networks are autonomous and delay-sensitive, non-orthogonal multiple access (NOMA) over these beams is considered for agility and efficiency. In particular, aiming to address these challenges of highly dynamic mobility, we propose a machine learning framework to enable agile analog beam management for mmWave-NOMA transmissions. The proposed beam management aims to achieve efficient beam tracking and NOMA-grouping-aware analog beamforming optimization to facilitate mmWave-NOMA transmissions by judiciously utilizing angular domain information (ADI). More specifically, a Gaussian process machine learning-based ADI prediction scheme is proposed to track the angular dynamics of FUAVs, which facilitates fast beam-tracking for mmWave-NOMA transmissions. Moreover, by exploiting the predicted ADI, an unsupervised-learning-based FUAV grouping scheme is proposed to facilitate mmWave-NOMA transmissions with high radio-frequency chain efficiency, while a deep learning-based NOMA-grouping-aware fast transmit beamforming optimization scheme is proposed to improve the coverage of mmWave-NOMA transmissions in highly dynamic multi-UAVs networks. Simulation results validate the performance advantages of our proposed beam management scheme against state-of-the-art schemes.

TL;DR: In this article, a theoretical investigation of vibration and sound radiation responses of laminated plates in thermal environments is presented, where first-order shear deformation theory and von Karman nonlinear strain displacement relationship are used to represent the dynamic deformation.
Abstract: This paper presents theoretical investigations of vibration and sound radiation responses of laminated plates in thermal environments. Static thermal stresses are taken into account to describe the stress state of the vibrating plate. First-order shear deformation theory and von Karman nonlinear strain displacement relationship are used to represent the dynamic deformation. And then, governing equations are obtained with Hamilton’s principle. Response characters are studied in both the pre and post-buckling ranges. Results show that the bending stiffness of the heated plate drops in the pre-buckling range and increases after thermal buckling occurs. Thermal environment preforms as two opposite effects before and after buckling. Amplitudes of vibration and radiated sound of the thermal post-buckled plates show opposite variation trends.
