DTRA BASIC RESEARCH
2
DTRA safeguards the United States and its Allies from Weapons of Mass Destruction (WMD) by providing capabilities to reduce,
eliminate, and counter the threat and mitigate its effects.
Nuclear Weapons... difficult to acquire,
devastating in use
Chemical Weapons... cheap and easy to make
... casualties not widespread
Biological Weapons…. not difficult to find/use
… attacks not quickly recognized, … casualties
propagate with time
Radiological Devices... dangerous to assemble with
high contamination impact… low lethality
High-Yield Explosives... easily available materials with many ways to deliver
… point targets WMDTHREATS
Providing Solutions Across the Full Spectrum of Combating WMD
DTRA Mission

RD-BA Directorate Focus
Foster farsighted, high payoff research focused on the unique challenges to prevent, reduce, eliminate, defeat
and mitigate threats from Weapons of Mass Destruction (WMD)
• Attract next-generation workforce
• Advance the fundamental knowledge and understanding in the sciences
• Promote university research to support WMD threat reduction
• Facilitate transition of research results to higher levels of S&T maturation
4
Impact:• Near real-time
support for pre-event predictions, damage assessments and strategies to remediate the effects of WMD attack (e.g. cascading failure, change in demand)
Motivation and Long-Term Objectives• Motivation: A WMD event will have a large geographic impact
simultaneously across multiple networks causing cascading failures and decreased capacity across networks with shifting demand
• Objectives: Expand understanding and identify methods/strategies for the response, resilience, and recovery of interconnected networks to the extreme environments associated with WMD effects DTRA Niche:
• Extreme conditions over a wide area simultaneously affecting multiple networks
• Cascading failures across infra-structure networks
• “Hardening” and mitigation strategies from impacts of WMD use
Current Practice:• Network structure and
dynamics are fairly well understood
• Early research into adaptive recovery of networks whose structure has changed
• Little to no capability to predict, prioritize or manage changed demand for remaining infrastructure capacity
Physical Networks & Network Theory

One potential WMD Environment
• A high altitude nuclear weapon burst can produce an “electromagnetic shock wave” covering a significant portion of the United States
• Such geographically-large “insults” simultaneously affect networks, their interconnections, and may induce cascading failure

Challenges & Barriers:
• Field is relatively nascent, little research in the DTRA niche exists
• Changing research focus to include cascading and interdependent networks
• Limited DTRA mission niche
Opportunities:
• Research on analyzing the robustness of interdependent networks
• Research on topology categorization for interdependent systems of networks
• Bio-inspired resilient network design
Objectives:• Identify factors for network robustness of interdependent networks
• Discover theory and create algorithms for WMD damage assessment

Physical Networks & TheoryNetwork Dynamics - Multiple
Failures
Challenges & Barriers:
• Fundamental models for dynamic topologies are needed
• Real networks are interdependent
Opportunities:
• Rapid analysis algorithms could contribute to containment and remediation of major damage
Objectives:• Identify behavior of networks including changes in network topologies over time

Physical Networks & Theory New Theories for Adaptive
Recovery
Challenges & Barriers:
• Lack of fundamental mathematical representations for network dynamics with changing topologies
• Inability to process massive data sets for data-to-decision close to real time
• Understanding of human cognition for autonomous systems
Opportunities:• Mathematical
methods for burst robustness and rapid analysis of cascading failures
• Strategies for network repairing and resource reallocation via topology, logic structures and multilayer network dynamics
• New theories to speed up data-to-decision process
Objectives:• Develop mathematical based strategies and techniques for identifying stopping cascading failures, repairing damaged networks, and ultimately for adaptive recovery from WMD attacks.

Physical Networks and TheoryModern Technical Network Behaviors
Challenges & Barriers:
• Abundance of network data available, but few characteristic events
• Validation of theory
Opportunities:
• Predict and prioritize changed demand and identify optimal strategies for allocation of remaining capacity under varying attack scenarios
Objectives:• Characterize
impact of changed demands on networks due to WMD attack
• Characterize Modern-technical feedback of networks and its impact
