Homeland Security-related Games

Shared by UAPI partner Richard White at the University of Colorado, Colorado Springs A large number of games and scenarios covering a range of topics including critical infrastructure protection, terrorism, pandemics, strategy, disaster response, border...

Budget Widget

The basic idea of the Budget Widget tool is that people have a limited budget (real world DHS amounts), and they have to decide where they will make cuts. You must be a CHDS...

MBRA (Model Based Risk Assessment)

Software. Ted Lewis. The MBRA tool supports the Model-Based Risk Assessment technique described in Critical Infrastructure Protection in Homeland Security (Lewis, 2015). There are two key components of MBRA: the network analysis and the...

Attacker Defender

Simulation/software — . Ted Lewis. Simulation of attacker and defender strategies in random, clustered, and scale-free networks. Shows that network hubs and betweener nodes are the most important in terms of both attacker and...

Bean Machine

Simulation/software — . Ted Lewis. Simulation of the Galton-Watson bean machine often found in science museums. Beans are dropped through a maze of left/right forks in the road, and land at the bottom in...

Catastrophe7

Simulation/software — . Ted Lewis. Three simulations: Sticks, Amaral-Meyer, and Random Catastrophes. Sticks illustrates how systems fail due to outside incidents. Amaral-Meyer illustrates intrinsic failure (internal faults), and Random Catastrophes illustrates how any layered...

Complex Cycles

Simulation/software — . Ted Lewis. ComplexCycles java application plots data stored in a comma separated values (csv spreadsheet) file as a limit cycle(s). It also shows Altman Z-score bounds on values, which is useful...

Distributions

Simulation/software — . Ted Lewis. This application produces the probability distributions for the sum (Normal), product(Gamma), minimum(Long-tailed), and maximum(long-tailed) of random numbers. It illustrates regression to the mean, extreme statistics, and the effect of...

Emergence

Simulation/software — . Ted Lewis. This java application demonstrates network emergence according to organizing principles: increase clusters, node degree, betweeness, and follow-the-leader. It also animates the spread of an epidemic, scale-free link percolation, link...

Flashmob

Simulation/software. Ted Lewis. The Flashmob java application simulates the formation of flash mobs in a network where nodes are either red or blue. A node is colored red with probability proportional to the number...

Forest Fires3

Simulation/software — . Ted Lewis. Simulated forest fires started by random lightening strikes. Illustrates the concept of percolation and shows how percolation leads to self-organized criticality and power law exceedence probability. Less frequent lightening...
