9 hours ago · Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light. The wavelength is the distance from one peak (crest) of the wave's electric field to the next, and is inversely proportional to the frequency of the wave. The relation of frequency and wavelength in a radio wave traveling in vacuum or air is.
9 hours ago · The spill continued to have documented impacts on wildlife in the Prince William Sound for over 10 years (Peterson et al., 2003). Recently, the BP Deepwater Horizon explosion in the Gulf of Mexico killed 11 workers and spilled an estimated 53,000–62,000 barrels of oil (Seis, 2012).
9 hours ago · Specifically, an MDP is a structure \({M}[\cdot ] = (S, A, P, R, S_0, H, \cdot )\) where S is an infinite set of continuous real-vector environment states which are valuations of the state variables \(x_1,x_2,\ldots ,x_n\) of dimension n (\({S} \subseteq \mathbb R^{n}\)), A is a set of continuous real-vector control actions which are valuations of the action variables \(u_1,u_2,\ldots ,u_m ...
