This book contains 67 papers presented at ICTCA2001. It includes three keynote addresses surveying the frontier developments in computational and theoretical acoustics. The papers cover aero-, seismo- and ocean acoustics, as well as ultrasonics. Computational methods, numerical simulation, theoretical analysis and experimental results are emphasized by different papers.The proceedings have been selected for coverage in:Index to Scientific & Technical Proceedings (ISTP ROM version / ISI Proceedings)Contents:Efficient Broadband Signal Simulation in Shallow Water: A Modal Approach (F B Jensen et al.)Recent Progresses on Shallow Water Reverberation (R H Zhang & F H Li)Anomalous Sound Propagation due to Bottom Roughness (F H Li et al.)The Use of 4D Seismic for Ocean Acoustic Tomography (F Accaino et al.)The Passive Acoustical Method of Monitoring and Measuring Sea Surface Wind Speeds (J H Lin et al.)Wave Propagation in Poroelasticity: Equations and Solutions (A Hanyga)Shear Wave Velocity Estimation in HTI Media (Q Z Du et al.)Theoretical Simulation of the Behavior of Micromachined Electrostatic Ultrasonic Transducers (L-F Ge)Lateral Resolution Enhancement of Ultrasound Images Using Neural Networks (R Carotenuto et al.)Finite Element Analysis on Waves Propagation in Cylinders (X M Wu & M L Qian)On Detecting the Source of Acoustical Noise (V Isakov)Wave Propagation and Imaging Using Gabor-Daubechies Beamlets (R-S Wu & L Chen)and other papersReadership: Graduate students, academics, researchers, and industrialists in computational physics, mathematical physics, geophysics, numerical computational mathematics and ocean engineering.Key Features:Traces the political, economic and social development of Hong Kong in the last 15 yearsExamines why economic integration has not brought Hong Kong socially and politically closer to mainland ChinaProvides an outlook of the challenges ahead for both Hong Kong and China
