In this paper, we discuss a model based software testing method for testing of the Web applications using StateCharts. To this end, we briefly describe the test coverage technique, editorial tools for drawing StateCharts, modeling concurrency in Web applications, and test metrics. A simple Web application has been used to show the feasibility of our(More)
Though subgraph matching has been extensively studied as a query paradigm in semantic web and social network data environments, a user can get a large number of answers in response to a query.

A link between two nodes represents a relationship such as communication, participation, or financial support. When stored in a database, these graphs can be searched and analyzed for(More)
The University of North Dakota is developing airspace within the state where Unmanned Aircraft Systems (UASs) can be flown without an onboard sense and avoid system or Temporary Flight Restrictions (TFRs). With funding from the U.S. Air Force, a mobile ground-based radar system capable of detecting aircraft operating in Class E airspace and the software to(More)
