Shin guards, pole guards, arm guards and chin guards are mainly used in slalom skiing in order to protect the body parts having impact with the gates. Back protectors and padding, also known as stealth, is worn for giant slalom and other speed events in order to better protect the body if an athlete were to have an accident at high speeds. [19]
The rotation group SO(3) has as a universal cover the group SU(2), which is isomorphic to the group of versors in the quaternions. This is a double cover since the kernel has order 2. (cf the tangloids.) The unitary group U(n) is covered by the compact group T × SU(n) with the covering homomorphism given by p(z, A) = zA. The universal cover is ...
The newer guidance system increased accuracy to a quoted figure of between 30 m (100 ft) and 90 m (300 ft). The AGM-129A, like the AGM-86B, is armed with a W80-1 variable-yield nuclear warhead. The first test missile flew in July 1985, and the first production missiles were delivered to the US Air Force in 1987.
The B-2's operational altitude imposes a flight time for defensive weapons that makes it virtually impossible to engage the aircraft during its weapons deployment. [citation needed] New stealth aircraft designs such as the F-22 and F-35 can open their bays, release munitions and return to stealthy flight in less than a second. [citation needed]
The Zumwalt-class destroyer is a class of three United States Navy guided-missile destroyers designed as multi-mission stealth ships with a focus on land attack. The class was designed with a primary role of naval gunfire support and secondary roles of surface warfare and anti-aircraft warfare.
The Lie algebra of SL(2, R), denoted sl(2, R), is the algebra of all real, traceless 2 × 2 matrices. It is the Bianchi algebra of type VIII. The finite-dimensional representation theory of SL(2, R) is equivalent to the representation theory of SU(2), which is the compact real form of SL(2, C).
General Sherman is a giant sequoia (Sequoiadendron giganteum) tree located at an elevation of 2,109 m (6,919 ft) above sea level in the Giant Forest of Sequoia National Park in Tulare County, in the U.S. state of California. By volume, it is the largest known living single-stem tree on Earth. [1]
Film Vehicle Owner Notes Live and Let Die: AEC Regent RT-type double-decker bus: Stolen by James Bond and Solitaire: Used to escape from San Monique's police force. The upper deck of this bus got torn off after Bond drove under a low bridge; the removed upper deck unintentionally came in useful, as a police car crashed into it and then drove into a lake
