The Kansa method with the Multiquadric-radial basis function (MQ-RBF) is inherently
meshfree and can achieve an exponential convergence rate if the optimal shape parameter …

This paper presents a noise propagation approach based on the Gaussian beam tracing
(GBT) method that accounts for multiple reflections over three-dimensional terrain topology …

Aerodynamic noise from the pantograph is significant when a train is running at high speeds
and can be important for noise inside the train as well as at the wayside. In this work, the …

The Kansa method is a well-established method for solving partial differential equation-
based problems. Nevertheless, it is still a relatively young, 30-year-old method, especially …

Sound propagation through sonic crystals has been widely studied both theoretically and
experimentally, because of its potential applications in many areas such as environmental …

Outdoor sound propagation benefits from algorithms that can handle, in a computationally
efficient manner, inhomogeneous media, complex boundary surfaces, and large spatial …

The sound attenuation in a sonic composite is studied using a new method that combines
the features of the piezoceramic theory, cnoidal method and genetic algorithms. A sonic …

Sound propagation through turbulent boundary layer (TBL) is of great significance in
transports where a TBL is attached to their external surfaces, for instance, air planes and …

Outdoor sound propagation, which propagates sound through inhomogeneous, moving
media with complex obstacles, presents challenging scenarios for computational simulation …

Acoustic fields and resonance responses from two spherical gas bubbles are investigated
using a time-domain simulation. Interior acoustic fields are obtained simultaneously from the …
