The Proving Ground consists of 1,498 acres (6.06 km 2) located less than one hour northwest of the Phoenix Sky Harbor Airport at an elevation of 1,650 feet (500 m). The facility was originally a Volvo facility (VAPG) but was transitioned to the Ford branding in the summer of 2009 and renamed the Arizona Proving Ground (APG). Volvo still is a ...

National Assessment of Educational Progress (NAEP); State achievement tests are standardized tests.These may be required in American public schools for the schools to receive federal funding, according to the US Public Law 107-110 originally passed as Elementary and Secondary Education Act of 1965, and currently authorized as Every Student Succeeds Act in 2015.
GM Desert Proving Ground in Mesa, Arizona, USA was a General Motors facility for the testing of HVAC, propulsion, and various automotive systems in a harsh climate. Opened in 1953, the closure of this facility was completed in 2009. It was replaced by a new facility in Yuma, Arizona, known as the Desert Proving Ground Yuma.
In aerospace engineering, spin stabilization is a method of stabilizing a satellite or launch vehicle by means of spin, i.e. rotation along the longitudinal axis. The concept originates from conservation of angular momentum as applied to ballistics , where the spin is commonly obtained by means of rifling .
SpinLaunch was founded in 2014 by Jonathan Yaney in Sunnyvale, California.The company's headquarters are in Long Beach. [6] In 2020 it opened a launch site. SpinLaunch continued development of its 140,000 square-foot (13,000 m 2) corporate headquarters in Long Beach, and of its flight test facility at Spaceport America in New Mexico.
Neutron spin echo is a time-of-flight technique. Concerning the neutron spins it has a strong analogy to the so-called Hahn echo, [13] well known in the field of NMR.In both cases the loss of polarization (magnetization) due to dephasing of the spins in time is restored by an effective time reversal operation, that leads to a restitution of polarization (rephasing).
The wheel was designed to test nerve reactions (sensitivity) as it rolled systematically across the skin. [1] A Wartenberg wheel is generally made of stainless steel with a handle of approximately 18 centimetres (7 in) in length. The wheel, which has evenly spaced radiating sharp pins, rotates as it is rolled across the flesh.
