RISReconstruction and Separation in a Semi-Free Field by Using the Distributed Source Boundary Point Method-Based Nearfield Acoustic Holography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a semi-free field, the acoustic field is composed of two components: the direct sound and the reflected sound. Because it is difficult to separate the direct sound from the acoustic field, ...
Determination of 18 Flutter Derivatives of Bridge Decks by an Improved Stochastic Search Algorithm
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the determination of the 18 flutter derivatives of bridge decks from three degrees-of-freedom (3DOF) free vibration data using an improved stochastic search algorithm (ISSA) combined with the unified ...
