Pieces Goals and Objectives

• Subsystem analysis. To develop tools for
  modeling and analyzing subsystems of structures
  typically found in a modern system,e.g.,
  airplane, missile, tank,automobile, ship, command
  post
• Topological analysis. To develop subsystem
  characterization techniques amenable to
  utilization in topological decomposition and
  topological analysis of complex systems

4
Subsystem or Substructure Analysis

• To develop an understanding of electromagnetic
  coupling mechanisms in systems and structures
• To develop the tools needed to predict the
  properties of a transient signal as it makes its
  way from the exterior of a structure or of a
  substructure, through a transmission path, to
  the terminals of a deeply embedded digital
  system
• To catalog the properties of transient signals
  that might be expected to reach digital systems
  as guidance to other MURI investigators who
  assess the reaction of a digital system to a
  transient stimulus

5
Topological Analysis

• To develop subsystem characterization techniques
  amenable to utilization in topological
  decomposition of complex systems
• To participate in the development of robust
  topological methods for characterizing the
  behavior of complex systems from topological
  knowledge of its constituent subsystems
• To exploit apriori-determined knowledge and
  matrix methods to analyze complex structures
