≈ 70 931.64 poundals (pdl) [note 6] Long ton-force. The long ton-force is equal to the weight of one long ton. one long ton-force = 2 240 lbf = 1 016.046 9088 kgf
In statistics, the uncertainty coefficient, also called proficiency, entropy coefficient or Theil's U, is a measure of nominal association. It was first introduced by Henri Theil [ citation needed ] and is based on the concept of information entropy .
The letters s,t,u are also used in the terms s-channel (timelike channel), t-channel, and u-channel (both spacelike channels). These channels represent different Feynman diagrams or different possible scattering events where the interaction involves the exchange of an intermediate particle whose squared four-momentum equals s,t,u , respectively.
Tensile toughness (or deformation energy, U T) is measured in units of joule per cubic metre (J·m −3), or equivalently newton-metre per cubic metre (N·m·m −3), in the SI system and inch-pound-force per cubic inch (in·lbf·in −3) in US customary units: 1.00 N·m.m −3 ≃ 0.000 145 in·lbf·in −3; 1.00 in·lbf·in −3 ≃ 6.89 kN ...
The USRA 2-8-8-2 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-8-2 wheel arrangement in the Whyte notation, or (1'D)'D1' in UIC classification.
where M 1 and M 0 are the mean anomalies at particular points in time, and Δt (≡ t 1-t 0) is the time elapsed between the two. M 0 is referred to as the mean anomaly at epoch t 0, and Δt is the time since epoch.
A similar canonical set of sigma points can be generated in any number of dimensions by taking the zero vector and the points comprising the rows of the identity matrix, computing the mean of the set of points, subtracting the mean from each point so that the resulting set has a mean of zero, then computing the covariance of the zero-mean set ...
The 2-8-8-2 was a design largely limited to American locomotive builders. The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983. Other equivalent classifications are: UIC classification: (1′D)D1′ French classification: 140+041
