2004 journal article

A high resolution computer model for sound propagation in the human thorax based on the Visible Human data set

*COMPUTERS IN BIOLOGY AND MEDICINE*, *34*(2), 177–192.

author keywords: sound propagation; human thorax; visible human data set; parallel computing

MeSH headings : Acoustics; Anatomy, Cross-Sectional; Computer Simulation; Humans; Male; Mathematical Computing; Models, Biological; Radiography, Thoracic; Respiratory Sounds / physiology; Thorax / physiology; Tomography, X-Ray Computed

TL;DR:
A parallel supercomputer model based on realistic tissue data is developed for sound propagation in the human thorax and the sound propagation behavior is analyzed under various conditions using artificial sound sources to confirm previous studies that show the size of the thorax plays a significant role in the type of sound generated at the chest wall.

2004 journal article

Modified integration rules for reducing dispersion error in finite element methods

*COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING*, *193*(3-5), 275–287.

author keywords: wave propagation; numerical dispersion; numerical integration; Helmholtz equation

TL;DR:
The method involves a simple shift of the integration points to locations away from conventional Gauss or Gauss–Lobatto integration points, which results in fourth-order accuracy with respect to dispersion error (error in wavelength), as opposed to the second- order accuracy resulting from conventional integration.

2003 journal article

On optimal finite-difference approximation of PML

*SIAM JOURNAL ON NUMERICAL ANALYSIS*, *41*(1), 287–305.

author keywords: absorbing boundary conditions; exponential convergence; finite differences; hyperbolic problems; perfectly matched layers; wave propagation; optimal rational approximations

TL;DR:
It is found that the minimal error can be achieved using pure imaginary coordinate stretching, and the PML discretization is algebraically equivalent to the rational approximation of the square root on [0,1] conventionally used for approximate absorbing boundary conditions.
