Traveling Techniques Decisive: RASMUSSEN, ras'moo-s'n, Knud Johan Victor, Danish Arctic explorer and ethnologist: b. Jakobshavn, Greenland, June 7, 1879; d. Gen-tofte, Denmark, Dec. 21, 1933. The fact that Rasmussen grew up among Eskimos, spoke their language perfectly, and learned their traveling techniques decisive techniques was decisive for his life and work. He began his career as an Arctic explorer in 1902-1904 as a member of the Danish Literary Greenland Expedition to the Thule district.
The techniques of peripheral photography permit the circumference of a cylindrical subject to be rendered as though spread out; and the nonperspective orthographic Camera can produce images with no vanishing point, in which uniformly sized subjects at different distances all appear as one size. The use of fiber-optic scanners permits the recording of images traveling techniques decisive from remote or inaccessible sites, even through a complex path.
Low-Noise traveling techniques decisive-Wave Tube.—The traveling techniques decisive-wave tube and a variant called the backward-wave tube provided a third means of low-noise microwave amplification. They are somewhat noisier than masers and parametric amplifiers, but are much superior to triode and pentode amplifiers at microwave frequencies. The traveling techniques decisive-wave tube is inherently a broadband device, while the backward-wave tube is a narrow-band amplifier that can be tuned over a wide band of frequencies by varying a d-c voltage. These characteristics have advantages in many applications. |
