Friends For Good - Wicked: A New Musical and the Idealization of Friendship

This rhetorical analysis explores the relationship between the two main characters, Elphaba and G(a)linda, in the musical Wicked through the interpersonal communication lens of friendship. This article focuses on the role that friendship plays in the musical and suggests that friendship is a relationship that can be stronger than romantic relationships. Through the application of Rawlins’ work on friendship to the relationship between Elphaba and G(a)linda, this analysis suggests that friendship is the most prominent relationship in Wicked. Wicked offers an im-portant message to theatre-goers: Friendship is something to be valued and cherished

Plasma Characterization of Hall Thruster with Active and Passive Segmented Electrodes

Non-emissive electrodes and ceramic spacers placed along the Hall thruster channel are shown to affect the plasma potential distribution and the thruster operation. These effects are associated with physical properties of the electrode material and depend on the electrode configuration, geometry and the magnetic field distribution. An emissive segmented electrode was able to maintain thruster operation by supplying an additional electron flux to sustain the plasma discharge between the anode and cathode neutralizer. These results indicate the possibility of new configurations for segmented electrode Hall thruster

Preliminary Numerical Assessment of Turbulent Flow Control with Plasma Actuators

A numerical investigation of damping of near-wall spanwise velocity fluctuations in a turbulent channel flow is carried out. Spanwise damping is realized with a body force which mimics the characteristic force distribution of plasma actuators. This force distribution is implemented in a direct numerical simulation. The body force is triggered by the signal of a sensor in upstream location. The control loop is applied with different actuator configurations, considering a spatially continuous and discontinuous body force distribution at the wall. The influence of distributed sensors and actuators of finite size on the control loop performance is investigated. The results show a reduction of the skin friction at the wall with maximum power saving rates up to 20%
