19. Wentworth & Hill's Examination Manuals. No. I: Arithmetic

Author

Wentworth, George Albert and Hill, George Anthony

Abstract

This manual is collection of examinations. The first part contains 150 examination papers, the questions for which have been selected mainly from the English, French, and German collections of problems. These papers may be divided into three groups. The first 50 papers are confined to the simple rules, fractions, and weights and measures; the next 50 papers cover all the subjects treated in ordinary text-books except the metric system; the last 50 also include the metric system. In each group the earlier papers will be found somewhat easier than the later ones. The papers are intended to be one-hour papers, but if any of them are thought to be too long for one hour, the time may be increased, or the length of the paper reduced by omitting one or more questions.

20. THE LANCHESTER ATTRITION-RATE COEFFICIENT: SOME COMMENTS ON SETH BONDER'S PAPER AND A SUGGESTED ALTERNATE METHOD.

Author

Barfoot, C. B.

Subjects
MATHEMATICS, REPENTANCE, ARITHMETIC, ARITHMETIC functions, HARMONIC functions, COMPLEX variables
Abstract

This note presents some comments on BONDER'S paper on the Lanchester attrition-rate coefficient, which indicate that a valid prediction of average attrition is obtained by using the harmonic mean of the variable attrition rates rather than the arithmetic mean. This change results in a constant Lanchester attrition-rate coefficient being defined as the reciprocal of the expected time to kill a target. An alternate and more general method for obtaining the constant coefficient is presented and some comparative results are displayed. An appendix indicates the conditions for which it is appropriate to use the harmonic and arithmetic means of rates in general. [ABSTRACT FROM AUTHOR]
