In the former case, when possible, an axiomatization is simply a recursive enumeration of validities of the logic considered.
The approximate concordance between our low optimal birth weight cutoffs and the 10th percentile among singletons is a testament to the general validity of this logic.
The validity of the fuzzy logic expert system is demonstrated by comparing the results with evaluations of the same soils using two other indicators of the physical soil quality for plant production: the least limiting water range (LLWR) and the S-parameter (i.e. the slope of the water retention curve at the inflection point).
The validity of the proposed fuzzy logic control has been demonstrated experimentally in a steel cantilever test beam and a set of experimental tests are made in the system to verify the efficiency of the on-line self-organizing fuzzy controller.
Judgments about whether to include an item were based on several factors: the degree to which a given item reflected how a particular aging perception was defined (content validity); the logic of a given item, specifically its meaning and readability for participants; and the validity and content coverage of items within the broader aging literature.
Generalisation is inherently difficult in all studies because 'whereas the problems of internal validity are solvable within the limits of the logic of probability statistics, the problems of external validity are not logically solvable in any neat, conclusive way' 3 (p. 17).
Most investors would quickly acknowledge the validity of this simple logic but then buy a stock and make the mistake of defaulting to a buy-and-hold approach.
Through our lols and OMGs, on three continents that span more than half the world, the underlying validity of Jacob's logic lingered between us.
Whoever, as Chrisippus did, accepts the validity of the principle of bivalence, opts for two-valued logic; whoever even partially rejects this principle, as Aristotle did, thereby opens the door to many-valued logic.
Furthermore, we demonstrate the validity of the proposed scheme using the BAN (Burrows, Abadi, and Needham) logic.
