Using Riemann-Liouville derivatives, we introduce fractional Sobolev spaces, characterize them, define WOMENS FOOTWEAR weak fractional derivatives, and show that they coincide with the Riemann-Liouville ones.Next, we prove equivalence of some norms in the introduced spaces and derive Tail bags their completeness, reflexivity, separability, and comp
Data assimilation is an important discipline in geosciences that aims to combine the information contents from both prior geophysical models and observational data (observations) to obtain improved model estimates.Ensemble-based methods are among the state-of-the-art assimilation algorithms in the data assimilation community.When applying ensemble-
We study the achievable rate of an uplink MIMO cognitive radio system where the primary user (PU) and the secondary user (SU) aim to communicate to the closest primary base station (BS) via a multi-access channel through the same unmanned aerial vehicle (UAV) relay.The SU message is then forwarded from the primary BS to the secondary network with a
