Experimental and numerical study on the effect of strain rate to ductile damage by Bowden, Andrew Scott

“…FEA modelling techniques were optimized to minimize computation time. The most important was the use of infinite elements to simulate the bars which, when calibrated, were found to be the ideal method of modelling split Hopkinson bars. …”

A granular flow model of an annular shear cell by Bremner, Sherry

“…The effect of two friction coefficients over a range of shearing wall velocities were examined in the DEM simulations. The data were examined over 3 selected radial lines and utilised to calculate the shear stress distribution and the power dissipation from the developed models. …”

Energy-detection based spectrum sensing for cognitive radio on a real-time SDR platform by Rwodzi, McBath John

“…The noise floor of the system is first analysed to determine the detection threshold, which is obtained using the empirical cumulative distribution method. Simulations are carried out using MATrix LABoratory (MATLAB) to set a benchmark. …”

The feasibility of a commercial-scale recirculating aquaculture system integrating sea urchins (Tripneustes gratilla) and seaweed (Ulva) by De Vos, Sebastiaan

“…Most of this nitrogen is likely deposited as particulates and thus cannot be utilized by Ulva. However, this nitrogen could be converted into a dissolved form via mineralization. …”
