Zine El Abiddine Fellah graduated from the University Science and Technology Houari Boumedienne, Algeria, in Physics (1996). He obtained a Ph.D. degree in Acoustics at the University of Le Mans in France (2000). He has worked at the Acoustic and Thermal Laboratory of Leuven, Belgium (2001), and at the Therapeutic Ultrasound Research Laboratory of the National Institute of Health and Medical Research, Lyon, France (2002–

2004). He is currently a research scientist at the Centre National de la Recherche Scientifique at Marseille, France. He received the Yves Rocard Prize in 2003 from the French Acoustical Society. His research interests are in the area of ultrasound, low-frequency measurements, direct and inverse problems, fractional calculus, porous media, fractals, micropolar media, and cancellous bone.

Erick Ogam pursued his secondary and higher education in Kenya and France, respectively. He received his PhD degree from the Université de Provence Aix-Marseille I, France, in 2007. He is currently a research engineer at the Laboratoire de Mécanique et d'Acoustique, UMR7031 CNRS, Marseille, France. His research interests include direct and inverse problems in acoustics and vibroacoustics, modeling ultrasonic wave propagation in com-

plex media, fluid structure interaction, non-linear vibration, developing acoustic and vibration transducers/sensors, data acquisition, generating real data, new experimental techniques, and signal processing.
