    URBAN-NET: A Network-based Infrastructure Monitoring and Analysis System for Emergency Management and Public Safety

    Abstract—Critical Infrastructures (CIs) such as energy, water, and transportation are complex networks that are crucial for sustaining day-to-day commodity flows vital to national security, economic stability, and public safety. The nature of these CIs is such that failures caused by an extreme weather event or a man-made incident can trigger widespread cascading failures,…

    Identifying the Critical Links in Road Transportation Networks: Centrality-based approach utilizing structural properties

    Surface transportation road networks share structural properties similar to other complex networks (e.g., social networks, information networks, biological networks, and so on). This research investigates the structural properties of road networks for any possible correlation with the traffic characteristics such as link flows those determined independently. Additionally,…

    Reliable Communication Models in Interdependent Critical Infrastructure Networks

    Modern critical infrastructure networks are becoming increasingly interdependent where the failures in one network may cascade to other dependent networks, causing severe widespread national-scale failures. A number of previous efforts have been made to analyze the resiliency and robustness of interdependent networks based on different models. However, communication networ…

    Utilizing Semantic Big Data for realizing a National-scale Infrastructure Vulnerability Analysis System

    Critical Infrastructure systems(CIs) such as energy, water, transportation and communication are highly interconnected and mutually dependent in complex ways. Robust modeling of CIs’ interconnections is crucial to identify vulnerabilities in the CIs. We present here a national-scale Infrastructure Vulnerability Analysis System (IVAS) vision leveraging Se- mantic Big Data (…

    The EPSA Project Finance Mapping Tool

    The Energy Policy and Systems Analysis Office of DOE has requested a tool to compare the impact of various Federal policies on the financial viability of generation resources across the country. Policy options could include production tax credits, investment tax credits, solar renewable energy credits, tax abatement, accelerated depreciation, tax-free loans, and others. Th…

    Common Operational Picture

    The COP strategy will consolidate and document design considerations and approaches for the full spectrum COP requirements based on a generic test installation. The design is documented as a listing, description and justification for a Common Operational Picture. The COP architecture is based upon the questions a commander requires for continued operation in a highthreat p…

    Automating Natural Disaster Impact Analysis: An Open Resource to Visually Estimate a Hurricane’s Impact on the Electric Grid

    An ORNL team working on the Energy Awareness and Resiliency Standardized Services (EARSS) project developed a fully automated procedure to take wind speed and location estimates provided by hurricane forecasters and provide a geospatial estimate on the impact to the electric grid in terms of outage areas and projected duration of outages. Hurricane Sandy was one of the wor…

    Real Time Simulation of Power Grid Disruptions

    DOE-OE and DOE-SC workshops (Reference 1-3) identified the key power grid problem that requires insight addressable by the next generation of exascale computing is coupling of real-time data streams (1-2 TB per hour) as the streams are ingested to dynamic models. These models would then identify predicted disruptions in time (2-4 seconds) to trigger the smart grid’s self h…
