- ItemOpen AccessMARIS - Capabilities and Applications for Security and Risk Analysis(2006-02-15) Jensen, April; Gavrilova, MarinaThis report contains a description of goals accomplished over the course of the project. It also contains descriptions of ideas for data analysis and progress made regarding these goals. New data that was created is described, including how it was generated, where it is stored and some particular goals that it may prove useful for. Finally, some figures are included to illustrate some of the uses of both ArcGIS and MARIS for the display and analysis of data with the goals of risk analysis and security.
- ItemOpen AccessNormal vs. Abnormal Behavior(2006-02-15) Jensen, April; Gavrilova, MarinaThe term outlier refers to data that deviates significantly from what is considered normal. Outliers are often of interest since they may indicate that data was generated by a mechanism other than the expected one [23], or may indicate abnormal or suspicious behavior. The modeling and analysis of normal vs. abnormal behavior proves useful in security-related areas such as biometrics, video surveillance and intrusion-detection, as well as in other areas such as medical imaging, among others.
- ItemOpen AccessRoutes - Modeling, Storage and Analysis(2006-02-15) Jensen, April; Gavrilova, MarinaThe modeling and analysis of routes and networks has been studied widely in computer science and other disciplines due to its large number of applications. Some of these include the planning of transportation routes, Internet routing and the location of emergency facilities. This paper will include a look at some topology-based methods for storing and analyzing routes, including the use of ArcGIS, as well as a look at Voronoi diagrams. Some potentially relevant network analysis methods will be discussed as well.
