(From ZHOU Yinqiu of Ultrasonic Physics and Exploration Laboratory) Dr. Miroslav Brajano from Curtin University of Technology paid a visit to IACAS and would do research work here for 3 months. During his visit, he would give a series of lectures on "Propagation of Elastic Waves in Porous Media".
On May 25, 2010, Dr. Miro gave the first lecture entitled "The principle of minimal action-basic law of nature" and the rest six lectures would be held every Tuesday from June 1to July 6. The series of lectures was highly valued by leaders of IACAS. WANG Xiaomin, director of the institute attended and made a welcome speech.
Dr. Miro is good at Rock Acoustic Physics. This subject which is now becoming a focus in researches of applied geophysics and geophysical prospecting is based on acoustic measurements of rocks, uses acoustic theories in porous medias, establishes a quantitive relationship between macroscopic elastic parameters of rocks and microscopic structures of porosity, directs the study of the theory and simulation of elastic waves propagation and the research of analysis and evaluation of elastic waves. Dr. Miro started from fundamental theories, explained the important physical concepts and laws such as the principle of minimal action, generalized coordinates, Calculus of variations, Lagrange function, Fermat's principle, Generalized Snell's law and so on. He made listeners understand abstract physical concepts better through a variety of problems solutions.
