Simulation-based calibration of geotechnical parameters using parallel hybrid moving boundary particle swarm optimization (2009)
Journal Article

Simulation-based optimization methods have been recently proposed for calibrating geotechnical models from laboratory and field tests. In these methods, geotechnical parameters are identified by matching model predictions to experimental data, i.e. b...

The effect of morphology upon mobility: Implications for bulk heterojunction solar cells with nonuniform blend morphology (2009)
Journal Article

We use a Monte Carlo model to predict the effect of composition, domain size, and energetic disorder upon the mobility of carriers in an organic donor-acceptor blend. These simulations show that, for the changes in local morphology expected within th...

Phosphorus removal from waste waters using basic oxygen slag (2009)
Journal Article

Few studies have characterized reactive media for phosphorus (P) removal in passive treatment systems in terms of both batch and continuous flow experiments. This study uses basic oxygen steel slag (BOS) from a U.K. feedstock. Batch experiments demon... Read More about Phosphorus removal from waste waters using basic oxygen slag.

Empirical mode decomposition, an adaptive approach for interpreting shaft vibratory signals of large rotating machinery (2009)
Journal Article

The Fourier transform (FT) has been the most popular method for analyzing large rotating machine shaft vibration problems, but it assumes that these vibration signals are linear and stationary. However, in reality this is not always true. Nonlinear a... Read More about Empirical mode decomposition, an adaptive approach for interpreting shaft vibratory signals of large rotating machinery.
