Whether or not you can have a negative log depends on what you actually mean by a negative log: We can take the negative of a log: - logₐ(x) = logₐ(1/x). But you can't compute the log of a negative number. Is log and ln the same? No, in most cases, log and ln ar...
Again, what does this α mean? Most important is its meaning to the mathematician, who thinks of local behavior of the form limb →∞log N(b)/log b = DBL. In the case of recursively defined records, try to cover a piece b′−k=b−1wide and b′′−khigh, using boxes of si...

The resistivity must be corrected to formation temperature using Eqn (9.2.6). 3. Refer to a water catalogue (e.g., Canadian Well Logging Society, 1987) and look up Rw for the formation of interest in the same geographical area. The resistivity must be corrected to formation temperature ...

Note that equation (23) defines the mixture time constant as a harmonic mean over the τ values that would have applied had the actives been applied individually on their own. Equation (23) defines the response of the system on the assumption that the active agents act independently in a ...
At the center (the 0 point in the image above) the median (the middle value in the set), the mode (the value that occurs most often), and the mean (arithmetic average) are all the same. The lognormal distribution differs from the normal distribution in several ways. A major ...
