    Automatic Modeling and Simulation of Networked Components
    (2011) Bruce, Nathaniel William; Koskie, Sarah; Chen, Yaobin; Li, Lingxi
    Testing and verification are essential to safe and consistent products. Simulation is a widely accepted method used for verification and testing of distributed components. Generally, one of the major hurdles in using simulation is the development of detailed and accurate models. Since there are time constraints on projects, fast and effective methods of simulation model creation emerge as essential for testing. This thesis proposes to solve these issues by presenting a method to automatically generate a simulation model and run a random walk simulation using that model. The method is automated so that a modeler spends as little time as possible creating a simulation model and the errors normally associated with manual modeling are eliminated. The simulation is automated to allow a human to focus attention on the device that should be tested. The communications transactions between two nodes on a network are recorded as a trace file. This trace file is used to automatically generate a finite state machine model. The model can be adjusted by a designer to add missing information and then simulated in real-time using a software-in-the-loop approach. The innovations in this thesis include adaptation of a synthesis method for use in simulation, introduction of a random simulation method, and introduction of a practical evaluation method for two finite state machines. Test results indicate that nodes can be adequately replaced by models generated automatically by these methods. In addition, model construction time is reduced when comparing to the from scratch model creation method.

    Exploring philanthropic aspects of public communication campaigns: an analysis of Smokey Bear
    (2017-09) Flaxbeard, Helene; Lenkowsky, Leslie; Grace, Kittie; Herrold, Catherine
    The Smokey Bear Campaign is one of the most popular and recognized public communication campaigns in the United States. The Advertising Council began the Smokey Bear campaign in 1944 and it is the longest running public communication campaign in the United States. Through a rhetorical narrative methodology, this study analyzed Smokey Bear advertising pieces from its inception through the present. The analysis of the advertising pieces was organized by narrative elements of the campaign, such as narration, themes, characters, and major and minor events with a focus on philanthropic composition relating to awareness and behavior change messaging. The following question is answered: what kind of messaging focus does the Smokey Bear campaign deploy and what aspect of philanthropy does the Smokey Bear campaign seem to be achieving? Conclusions on the philanthropic aspects of public communication campaigns are drawn based on the analysis of the Smokey Bear campaign.
