The efficient use of appropriate calibration standards and the correction for the attenuation of the gamma rays within an assay sample by the sample itself are two important and closely related subjects in gamma-ray nondestructive assay. Much research relating to those subjects has been done in...

A previous report explored and discussed statistical methods and procedures that may be applied to validate the survivability of a complex system of systems that cannot be tested as an entity. It described a methodology where Monte Carlo simulation was used to develop the system survivability...

Periodic testing or examination is conducted routinely for some critical standby equipment or instrumentation, in an attempt to increase its availability. This is often called ``surveillance testing.`` There is a finite probability that tested equipment will be left in a degraded or...

The Homeland-Defense Operational Planning System (HOPS), is a new operational planning tool leveraging Lawrence Livermore National Laboratory's expertise in weapons systems and in sparse information analysis to support the defense of the U.S. homeland. HOPS provides planners with a basis to make...

In order to devise an algorithm for autonomously terminating Monte Carlo sampling when sufficiently small and reliable confidence intervals (CI) are achieved on calculated probabilities, the behavior of CI estimators must be characterized. This knowledge is also required in comparing the...

Three functions (i.e., SENSE, PLAN, and EXECUTE) make up the essential functionality for the battle management/command, control, and communications element of the Global Protection Against Limited Strike system. This report focuses on issues related to the SENSE function to support the...
