Al Hubbard was a “charlatan, bootlegger, radio pioneer, top-secret spy, uranium entrepreneur and billionaire,” according to HistoryLink.org. Naturally, Brad Holden became fascinated with him. Holden, ...
During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
Abstract: There has been a growing interest in the evolution of steerable parametric array loudspeakers for manipulating highly directional audio beams without mechanical steering. Given this ...
Abstract: Trajectory clustering is an essential task in spatial data mining. To address this problem, many previous studies either extended traditional clustering algorithms with spatial features of ...
