The likelihood-ratio test, also known as Wilks test, [2] is the oldest of the three classical approaches to hypothesis testing, together with the Lagrange multiplier test and the Wald test. [3] In fact, the latter two can be conceptualized as approximations to the likelihood-ratio test, and are asymptotically equivalent.
It is 8 + 1 ⁄ 2 inches (22 cm) long with flap open; approximately 4 + 1 ⁄ 2 inches (11 cm) wide, and forms a 4 inches (10 cm) deep pocket. It has a metal snap-type fastener closure and is attached to the individual equipment belt or individual equipment belt suspenders by a single slide keeper.
SAFER. Simplified Aid For EVA Rescue ( SAFER) is a small, self-contained, propulsive backpack system ( jet pack) worn during spacewalks, to be used in case of emergency only. If an untethered astronaut were to lose physical contact with the vessel, it would provide free-flying mobility to return to it. It is worn on spacewalks outside the ...
n -back. n. -back. The n-back task is a continuous performance task that is commonly used as an assessment in psychology and cognitive neuroscience to measure a part of working memory and working memory capacity. [ 1] The n -back was introduced by Wayne Kirchner in 1958. [ 2] N-Back games are purported to be a training method to improve working ...
Tensile testing, also known as tension testing, [ 1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area. [ 2]
An intact ACL should prevent forward translational movement ("firm endpoint") while an ACL-deficient knee will demonstrate increased forward translation without a decisive endpoint - a soft or mushy endpoint indicative of a positive test. More than about 2 mm of anterior translation compared to the uninvolved knee suggests a torn ACL ("soft ...
[2] Damage to the motor nerve supply of the lateral gluteal muscles (gluteus medius muscle and gluteus minimus muscle) Polio involving L5 (foot drop may also be seen because L5 innervates the tibialis anterior muscle). [3] Damage to the superior gluteal nerve. Temporary or permanent weakness of the lateral glutei Tendinitis. Penetrating injury.
Suitcase nuclear device. H-912 transport container for Mk-54 SADM. A suitcase nuclear device (also suitcase nuke, suitcase bomb, backpack nuke, snuke, mini-nuke, and pocket nuke) is a tactical nuclear weapon that is portable enough that it could use a suitcase as its delivery method. Both the United States and the Soviet Union developed nuclear ...
