      Acoustic localization of antbirds in a Mexican rainforest using a wireless sensor network 

      Collier, T. C.; Kirschel, A. N. G.; Taylor, C. E. (2010)
      Acoustic localization is a promising method to passively observe vocal animal species, but remains difficult and time consuming to employ. To reduce the labor intensity and impact of deployment, an acoustic localization ...

      Character displacement of song and morphology in African tinkerbirds 

      Kirschel, A. N. G.; Blumstein, Daniel T.; Smith, T. B. (2009)
      Divergence in acoustic signals between populations of animals can lead to species recognition failure, reproductive isolation, and speciation. Character displacement may facilitate coexistence of species in natural ...

      The method of fundamental solutions for axisymmetric acoustic scattering and radiation problems 

      Karageorghis, Andreas; Fairweather, G. (1998)
      The method of fundamental solutions (MFS) is applied to acoustic scattering and radiation for axisymmetric bodies and boundary conditions. The fundamental solution of the governing equation and its normal derivative, which ...

      Tissue harmonic ultrasonic imaging 

      Averkiou, Michalakis A. (2001)
      Harmonic imaging was originally developed for microbubble contrast agents in the early 90s under the assumption that tissue is linear and all harmonic echoes are generated by the bubbles. In fact, tissue, like bubbles, is ...
