To achieve a superior, more accurate simulation model for next generation progressive collapse of buildings, Applied Science International proposes use of the Applied Element Method (AEM) as the core solver of a fast running software tool for evaluating structural integrity following a blast or other extreme loading event. Due to its simplicity in modeling, speed of computing, constitutive models, ...

Standoff detection of nuclear materials continues to be one of the most critical tasks that security specialists must confront in a wide variety of applications, both military and civilian. There have been several approaches for standoff nuclear material detection. Each of them utilizes a different fundamental property of nuclear materials to improve the sensitivity of detection. In this SBIR prog ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

STANDARD MONTE CARLO AND FN METHODS FOR RADIATION TRANSPORT WILL BE USED TO STUDY A NEWLY PROPOSED SHIELD CONFIGURATION FOR PROTECTION AGAINST PARALLEL OR SLIGHTLY DIVERING GAMA RAY BEAMS IN A SPACE (NON-SCATTTERING) ENVIRONMENT. THE NEW CONFIGURATION EMPLOYS LAYERED SHIELDS, WITH CONSIDERABLE SEPARATION BETWEEN THE LAYERS, TO SHADOW THE TARGET, OF THE ASSUMPTION THAT THE DIRECTION OF INCIDENCE IS ...
