WebWe show how reinforcement learning can be used for this type of balloon. Specifically, we use the soft actor-critic algorithm, which on average is able to station-keep within 50\;km for 25\% of the flight, consistent with state-of-the-art. Furthermore, we show that the proposed controller effectively minimises the consumption of resources ...

WebProperties of Helium. Helium is an odorless, colorless and non-combustible gas. Furthermore, helium is lighter than air. Moreover, this gas is slightly soluble in water and … WebAnswer (1 of 2): If you just want a helix curve, we can put the circular projection in the x-y plane, then use z as a parameter, like so: \left\{ \begin{aligned} \ x\ &= \ \cos{z} \\ \ y\ &= \ … WebThe recombination of hydrogen and helium at z~1000-7000 gives unavoidable distortions to the Cosmic Microwave Background (CMB) spectrum. We present a detailed calculation of the line intensities arising from the Ly-alpha (2p-1s) and two-photon (2s-1s) transitions for the recombination of hydrogen, as well as the corresponding lines from helium. We give … buchstaller roth
