Genetic algorithm-based decision support for optimizing seismic response of piping systems
Journal of Structural Engineering, 131(3), 389–398.
Contributors: A. Gupta n, P. Kripakaran n, G. Mahinthakumar n & J. Baugh Jr.
TL;DR:
This paper describes computational approaches used in a prototype decision support system (DSS) for seismic design and performance evaluation of piping supports and a novel seeding technique, which overcomes the inefficiencies of conventional methods in the context of pipe support optimization.

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.

A hybrid MPI-OpenMP implementation of an implicit finite-element code on parallel architectures
INTERNATIONAL JOURNAL OF HIGH PERFORMANCE COMPUTING APPLICATIONS, 16(4), 371–393.
TL;DR:
A hybrid implementation adapted for an implicit finite-element code developed for groundwater transport simulations is presented, finding that while the hybrid model is a promising approach for SMP cluster architectures, the payoff may not be justified for converting all existing MPI codes to hybrid codes.
