Oct 07, 2015· To understand this formula, let's assume your heat map is a 5 x 5 matrix. If the likelihood and severity (or impact) of a risk are 4, your initial score would be 16. Rating velocity as, for example, Hours to Days = 3, Days to Weeks = 2, and Weeks to Months = 1, you then add in velocity to the calculation giving respective scores of 17, 18 and 19.

Möbius transformation - Wikipedia

1) for each A ∈ SL(2, C), and this action of SL(2, C) preserves the determinant of X because det A = 1 . Since the determinant of X is identified with the quadratic form Q, SL(2, C) acts by Lorentz transformations. On dimensional grounds, SL(2, C) covers a neighborhood of the identity of SO(1,3). Since SL(2, C) is connected, it covers the entire restricted Lorentz group SO + (1,3 ...

Using Vibration Analysis to Test for Bearing Wear

The IRD General Machinery Vibration Severity Chart, summarized in Table 1, is the most common example of absolute criteria and is a good guide for engineers who do not have any historical data on a machine. Each increment of machinery condition is represented by change of a factor of two in the vibration velocity.
