In this letter, we propose a novel network architecture for integrating terrestrial and non-terrestrial networks (NTNs) to establish connection between ground stations which are unconnected due blockage. We new framework where reconfigurable intelligent surface (RIS) is mounted on an aerodynamic high altitude platform station (HAPS), referred as HAPS-RIS. This can be one of the promising candid...

Here, we analyse the energetics, performance and optimization of flight in a moving atmosphere. We begin by deriving a succinct expression describing all of the mechanical energy flows associated with gliding, dynamic soaring and thermal soaring, which we use to explore the optimization of gliding in an arbitrary wind. We use this optimization to revisit the classical theory of the glide polar,...
