Two NAG members presented at the 2013 UNL Undergraduate Research Conference on April 11, 2013: (1) Adam Buck on “Analyzing the Time Variance of Orchestral Instrument Directivities” and (2) Josh Thede on “Acoustic Properties of Porous Material with Varying Surface Profiles”. They both did a great job! Their research projects were supported by UNL Undergraduate Creative Activities and Research Experiences (UCARE) grants.
