A time series analysis of U.S. Army officer loss rates / A time series analysis of United States Army officer loss ratesSparling, Steven J. 06 1900 (has links)
Accurate prediction of officer loss behavior is essential for the planning of personnel policies and executing the U.S. Army's Officer Personnel Management System (OPMS). Inaccurate predictions of officer strength affect the number of personnel authorizations, the Army's budget, and the necessary number of accessions. Imbalances of officer strength in the basic branches affect the Army's combat readiness as a whole. Captains and majors comprise a critical management population in the United States Army's officer corps. This thesis analyzes U.S. Army officer loss rates for captains and majors and evaluates the fit of several time series models. The results from this thesis validate the time series forecasting technique currently used by the Army G1, Wintersmethod additive.

The Gibbs’ phenomenon for Fourier–Bessel seriesFay, TH, Kloppers, PH 01 January 2003 (has links)
Summary
The paper investigates the Gibbs’ phenomenon at a jump discontinuity for
Fourier–Bessel series expansions. The unexpected thing is that the Gibbs’
constant for Fourier–Bessel series appears to be the same as that for Fourier
series expansions. In order to compute the coefficients for Fourier–Bessel
functionsefficiently, several integral formulasare derived and the Struve
functions and their asymptotic expansions discussed, all of which significantly
ease the computations. Three numerical examples are investigated. Findings
suggest further investigations suitable for undergraduate research projects or
small student group investigations.

Classroom notes: Summing sequences having mixed signsFay, TH, Walls, GL 11 June 2003 (has links)
Summary
A result is discussed which permits the summing of series whose terms have
more complicated sign patterns than simply alternating plus and minus. The
Alternating Series Test, commonly taught in beginning calculus courses, is a corollary. This result, which is not difficult to prove, widens the series summable
by beginning students and paves the way for understanding more advanced
questions such as convergence of Fourier series. An elementary exposition is
given of Dirichlet’s Test for the convergence of a series and an elementary
example suitable for a beginning calculus class and a more advanced example
involving a Fourier series which is appropriate for an advanced calculus class
are provided. Finally, two examples are discussed for which Dirichlet’s Test
does not apply and a general procedure is given for deciding the convergence or
divergence of these and similar examples.

Fourier series and elliptic functionsFay, TH 31 July 2003 (has links)
Summary
Nonlinear secondorder differential equations whose solutions are the
elliptic functions sn(t, k), cn(t, k) and dn(t, k) are investigated. Using Mathematica,
high precision numerical solutions are generated. From these data, Fourier
coefficients are determined yielding approximate formulas for these nonelementary
functions that are correct to at least 11 decimal places. These
formulas have the advantage over numerically generated data that they are
computationally efficient over the entire real line. This approach is seen as
further justification for the early introduction of Fourier series in the undergraduate
curriculum, for by doing so, models previously considered hard or
advanced, whose solution involves elliptic functions, can be solved and plotted
as easily as those models whose solutions involve merely trigonometric or other
elementary functions.

Basic Fourier TransformsCumbie, James Randolph 01 1900 (has links)
The purpose of this paper is to develop some of the more basic Fourier transforms which are the outgrowth of the Fourier theorem. Although often approached from the standpoint of the series, this paper will approach the theorem from the standpoint of the integral.
