The defined distance for a particular chambering is published in the TDCC data sheet of the chambering. In a rifle cartridge case like the .308 Winchester, the TDCC M = 25.00 value denotes the transducer must be positioned at a distance of 25 millimetres (0.98 in) from the breech face. [2]
Bolt thrust or breech pressure is a term used in internal ballistics and firearms (whether small arms or artillery) that describes the amount of rearward force exerted by the propellant gases on the bolt or breech of a firearm action or breech when a projectile is fired.

A common metric for quantifying losses in the case of work accidents is the present value of lost future earnings and medical costs associated with the accident. [2] In the case when the probability of loss is assumed to be a single number , and is the loss from the event occurring, the familiar form of the Hand formula is recovered.
In oil field tubing, buttress thread is a pipe thread form designed to provide a tight hydraulic seal. The thread form is similar to that of Acme thread [10] but there are two distinct threaded portions of differing diameters and profiles, the larger having a wedging profile, with a tapered sealing portion in between the larger and smaller diameters.
In mathematics, an event that occurs with high probability (often shortened to w.h.p. or WHP) is one whose probability depends on a certain number n and goes to 1 as n goes to infinity, i.e. the probability of the event occurring can be made as close to 1 as desired by making n big enough.
The values on the risk axis were determined by first determining risk impact and risk probability values in a manner identical to completing a 7 x 7 version of the modern risk matrix. [7] A 5 x 4 version of the risk matrix was defined by the US Department of Defense on March 30 1984, in "MIL-STD-882B System Safety Program Requirements". [8] [9]
Diagram showing the cumulative distribution function for the normal distribution with mean (μ) 0 and variance (σ 2) 1. These numerical values "68%, 95%, 99.7%" come from the cumulative distribution function of the normal distribution.
