GF(2), the Galois field of 2 elements, alternatively written as Z 2; Z 2, the standard axiomatization of second-order arithmetic; Z², an album by Devin Townsend; German destroyer Z2 Georg Thiele, a Type 1934 destroyer in the German Kriegsmarine; USS Ringgold, a destroyer transferred to the German Navy as Z-2 in 1959; Westinghouse Airships Z-2 ...
Ruhrstahl X-7 "Rotkäppchen" (German: Rotkäppchen, lit. 'Little Red Riding Hood') also known as Kramer X-7 or Ruhrstahl-Kramer RK 347 was a German wire-guided anti-tank guided missile (now referred to as MCLOS) developed during World War II by Ruhrstahl AG in 1943, after the Waffenamt (Army Ordnance Board) placed an urgent order for anti-tank missiles, this project was under the leadership of ...
Hasse diagram of the lattice of subgroups of Z 2 3. The red squares mark the elements of the subsets as they appear in the Cayley table displayed below. There are Z 2 3 itself, seven Z 2 2, seven Z 2 and the trivial group. The gray numbers are the index numbers of A190939.
The Boeing X-66 is an experimental airliner under development by Boeing. It is part of the X-plane series, and is being developed in collaboration with NASA and its Sustainable Flight Demonstrator program. It will use an extra-long and thin wing design stabilized by diagonal bracing struts, which is known as a Transonic Truss-Braced Wing.
The first combines under that name, the All-Crop 60, had a 60-inch, sickle-bar cutting head, and the popular Model 66 had a 66-inch cutting head. Many of these units are still in working condition, and they are well known for their dependability and low maintenance; however, as they are quite small machines (and now very old), they are not ...
The Lockheed X-7 (dubbed the "Flying Stove Pipe") is an American unmanned test bed of the 1950s for ramjet engines and missile guidance technology. It was the basis for the later Lockheed AQM-60 Kingfisher , a system used to test American air defenses against nuclear missile attack.
The newer Z machine can now shoot around 26 million amperes [23] (instead of 18 million amperes previously) in 95 nanoseconds. The radiated power has been raised to 350 terawatts and the X-ray energy output to 2.7 megajoules. In 2006 wire array experiments reach ultra-high temperatures (2.66 to 3.7 billion kelvins). [24]
The (−2, 3, 7) pretzel knot has 7 exceptional slopes, Dehn surgery slopes which give non-hyperbolic 3-manifolds. Among the enumerated knots, the only other hyperbolic knot with 7 or more is the figure-eight knot, which has 10. All other hyperbolic knots are conjectured to have at most 6 exceptional slopes. A pretzel (−2,3,7) pretzel knot.
