Historical measurements taken at weapons tests in the Nevada and Pacific Proving Grounds were evaluated in terms of the theoretical causes of irregularities and the predicted distribution patterns generated by various fall-out models. The general conclusions were that the present state of knowledge of the details of fall-out distributions is grossly inadequate, and the traditional cigar-shaped patterns are undoubtedly inadequate for describing fall-out patterns from nuclear attack.

The tables include: 1. The values of total field intensity (R) and Mcllwain's magnetic shell parameter (L) for altitudes from zero to tw.o thousand kilometers, 2. The detailed value of total field intensity near the South Atlantic anomaly, 3. The traces in both hemispheres of points with a fixed value of B and L. It is a pleasure to express our sincerest appreciation to Lt. Col. Billy McCormac of DASA for his encouragement and stimulating discussions. Similarly it is our pleasure to express our sincere appreciation to Major R. Pennington of DDRE and Dr. C.E. McIlwain of U.C. San Diego for contributing their computer codes, as well as F.H. Sage for the code which locates the geomagnetic equator.

In present practice these parameters are initially estimated and later adjusted by trial and error to improve the ability of the ...

Much of the contraversial nature of work in this field is the result of extremely imprecise foundations and lack of attention to the underlying statistical and semantic models.A satisfactory semantic model can be found in the concept of semantic atom. Notwithstanding a number of philosophical objections, the semantic atom is an operationally feasible support for a lexicon which is a semantic subset of all possible meanings and at the same time, exhausts the vocabulary of a language. Lexical decay is the process by which the lexical item covering an atom is replaced by another lexical item.Exponential lexical preservation is, in this model, directly analogous to decay phenomena in nuclear physics. Consistency requires that the decay process involved in exponentially preserved vocabularies be a Poisson process. This shows how to form test vocabularies for dating and proves that presently used vocabularies are not correctly formed.Dialectation studies show that historically diverging populations must be modelled by correlated Poisson processes. Definitive statistical treatment of these questions is not possible at this time, but much desirable research can be indicated.
