  • A standalone collaboration tool called ScreenBoard, which operates in a peer-to-peer fashion over the Internet and allows participants to share and annotate the contents of their computer screens in real-time. ScreenBoard allows collaboration across multiple applications.
  • A programmable collaboration library with an application programming interface (API).  The library enables collaboration through a particular application.  The NISAC Agent-Based Laboratory for Economics (N-ABLE) 2.0 tool, an agent-based economic modeling and simulation package, is the first NISAC project to use it.
  • High-level representation of Ethylene chemical family
  • FASTMap disrupted assets report
  • Critical interdependencies among electric power, telecommunications, transportation and emergency services intensify disruption effects on population and extend restoration times for all infrastructures.
  • Communications networks in different metropolitan areas have different levels of robustness during failures and overloads. This result could not have been discovered with standard performance modeling or reliability tools that assume random failures of individual nodes due to software or hardware failures.
  • Overloads in one network would cause overloads in other networks; implies new engineering rules to increase the robustness of overall networks.
  • Significant call blocking occurred due to simulated loss of 12 wireless and 18 wireline switches in the Houston metro area. Nodes represent switches and lines represent trunks connecting the switches.  Blocking Legend  Red = > 75% Orange = 50% to 75% Yellow = 35% to 50% Blue = 20% to 35% Green = 10% to 20% Grey = < 10%
