There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
This thesis discusses the application of control theory in the study of complex networks, drawing inspiration from the behavior of social networks. There are three topic areas covered by the thesis. The first area considers the ability to control a dynamical system which evolves over a network. Specifically, this thesis introduces a novel network controllability notion known as herdability. The second area of study, which builds directly on the first, is the application of herdability to the study of complex networks. Specifically, this thesis explores how to make a network herdable. The third and final area explores modeling the spread of the adoption of a beneficial behavior or an idea in such a way that the spread is encouraged by the action of a social network. A novel model of awareness-coupled epidemic spread is introduced, in which agents in a network are aware of a virus (here representing something which should be spread) moving through the network.
