Abstract: This letter studies the problem of prescribed-time stabilization for a class of uncertain nonlinear systems by adaptive dynamic programming. The results of this letter depend on the special ...

Abstract: This paper proposes a hybrid beamforming framework for massive multiple-input multiple-output (MIMO) in near-space airship-borne communications. To achieve high energy efficiency (EE) in ...

Both purported models could feature a smaller dynamic island, with the tech giant anticipated to move some of the Face ID technology, such as the flood illuminator, underneath the screen. Under the ...
