    How Culture Influences Our Expectations of Others

    Factors that lead into expectancies in certain communication situations will vary in great contrast according to the situation. This study tested whether thinking of a fundraiser as culturally similar to or different from oneself made a difference in several outcomes. Participants were asked to read one of two scenarios and fill out the corresponding questions. This study found that a combination of factors play a role in expected behaviors of others. It is a combination of age, race, ethnicity, gender, and social setting that influence perceptions of what should happen in a given situation. One factor may indeed have a greater role in perceptions of the behavior of others, but all of these factors have influence on expected behaviors. As was seen in this study, sometimes the social setting can trump all other factors in terms of the importance in gauging expectations

    The Effects of Elasticity in the Foundation on the Flutter of a Metallic High Aspect Ratio Wing

    The goal of this thesis is to study the flutter characteristics of a metallic high-aspect ratio wing, with linearly varying chord across the semis-span, and a simulated elastic foundation. The general planform of the wing is similar to the one found in a High- Altitude Long-Endurance Uninhabited Aerial Surveillance Vehicle (HALE USAV). The problem is studied using a simplified aerodynamic loading based on thin-airfoil theory, which is then combined with a Lagrangian formulation to solve the system as stationary. The wing has no control surfaces or external stores, and is modeled as a uniform beam with known mechanical properties, being attached to a combination of torsion springs at the root to reproduce the elastic foundation. The analysis of the problem includes the development of a Matlab code, which permits different root conditions to be defined, and computes the flutter speed and frequency, outputting information in the form of plots and data lists, making the analysis easy to follow
