Uncertainties in certain features of target geometries result in a loss of confidence in the signature assessment of the target. Knowledge of the impact to a target's radarcross section (RCS) due to changes to specific target features can assist to identifywhether uncertainty in a certain target feature warrants a loss of confidence in the targetsignature. This study will allow a development of a general "rule-of-thumb" on how theradar signature of a target varies as a function of the target's specific target features. Thetargets of interest which this study is centered around are fictitious ballistic missiles.Four target features that were investigated: fin size, nosecone shape, effect of panelriveting along the sides of the missile and the effects of heat shielding on the nosecone.By varying each of the four target features into a missile configuration and comparing toanother configuration, a relationship between specific target features and its effect on theradar cross section of a ballistic missile can be obtained. Based on the range of possibleconfigurations that target's feature can take, it is possible to estimate a range of possiblevalues of the radar signature. This will enable the user of the signature data to have abetter understanding of the target being assessed and target characteristics when acomplete knowledge of target configuration is unavailable.

The year 2003 marked the tercentenary of the birth of Jonathan Edwards (1703-1758), the man perpetually hailed as "America's most original religious thinker." Edwards's impact, both on colonial religious life and on the Anglo-American world of his day, was internationally acknowledged, and his legacy for the century and a half and more after his death in 1758 has been profound. Even to this day, Edwards's life is studied and his writings consulted on a global basis more than any other American theologian. The most significant scholarly conference marking the Edwards tercentenary took place in October 2003 at the Library of Congress in Washington, D.C. The papers from that gathering are presented in this volume. They represent much of the best and most recent work being done on Edwards and reflect the wide diversity of approaches to his life, thought, and legacy.
