Multiple Reference Impact Testing of Bridges Using a Network of Low-Cost Dynamic Exciters
<p>Multiple Reference Impact Testing (MRIT) is a form of Experimental Modal Analysis (EMA) that can be used to identify the dynamic properties of full-scale bridges. These dynamic properties include natural frequencies, mode shapes, damping ratios, modal scaling and modal flexibility. Since these …

Power system transient stability analysis of stiff systems using the Multirate method
… Application of the Multirate method on exciters provides a time savings for each time step, with the largest being a 10 percent faster solution when using a one cycle per second time step.

Voltage and stability analysis of distribution networks with non-conventional energy sources
… are represented by the two-axis models, the exciters by IEEE Type-1 models and the loads are modelled as constant impedances. To save programming time, it has become common to limit the machine and exciter representations to some specified models. The network admittance matrix is reduced by …

Insourcing a government information system: a case study from Malaysia.
… from grounded theory to analyse the data, seven exciters and six inhibitors of insourcing a government information system were identified and mapped in the analytical framework. Further, this is the first research to use an enhanced model, devised by combining the OPTIMISM model and two distinct …

Response of Electrified Micro-Jets to Electrohydrodynamic Perturbations
… (EHD) perturbations which were introduced by exciters driven by alternating voltage of sweeping frequency. Three different jetting mechanisms are used to generate jets with various ranges of jet diameters: ~150 micrometer inertial jets from liquid pressurized through a small orifice, ~50 …
