Simulation and gaming can support decision making through all phases of incident management including prevention, preparedness, response, recovery and mitigation. A number of gaming and simulation tools have been developed for the purpose but they generally utilize proprietary or unique data interfaces and their own view of partitioning the application and solution space. This creates a large o...

We introduce a new matrix model that describes Causal Dynamical Triangulations (CDT) in two dimensions. In order to do so, we introduce a new, simpler definition of 2D CDT and show it to be equivalent to the old one. The model makes use of ideas from dually weighted matrix models, combined with multi-matrix models, and can be studied by the method of character expansion.

We propose the set of operations for querying the conceptual schema of an objectoriented database. The operations form the basis of an algebra for objects called OVAL. They are de ned using the constructs introduced for our formalization of the object-oriented database model. The operations allow a user to query: (i) associations among individual objects, (ii) relationships between individual o...

Prior work supports the pedagogical value of conceptual maps for offering students an overview of a topic as well as the connections between subtopics. In this poster we describe a system that uses automated topic modeling technology to map the topics and sub-topics in a collection of documents. An interactive graphical representation allows users to explore this topic analysis, using it as an ...
