Full Field Reconstruction Enhanced With Operational Modal Analysis and Compressed Sensing for General Dynamic Loading
… full field measurement techniques, the expansion approach involves analytically expanding the limited measurements to all the degrees of freedom of the structure. Among all the analytical methods, the modal expansion method is computationally efficient and thus more suitable for real …

Control of sound transmission into payload fairings using distributed vibration absorbers and Helmholtz resonators
… as a first approximation of the system. A modal expansion method is used to describe the behavior of the cylindrical shell and the acoustic cavity; the noise reduction devices are modeled as surface impedances. All the elements are then fully coupled using an impedance matching method. This …

Stability analysis of a natural circulation lead-cooled fast reactor
… In order to capture the regional effects, modal expansion method which incorporates higher azimuthal modes is used to model the neutronics part of the system. A reduced order model is used in this work for the thermal-hydraulics. Consistent with the number of heat exchangers (HXs), the …

Unified conformal/nonconformal domain decomposition methods for solving large-scale multi-region electromagnetic problems
… element tearing and interconnecting (FETI-DP) method for the full-wave analysis of large-scale electromagnetic problems in three dimensions. These algorithms are designed to expand the capability of the FETI-DP method to accommodate more flexible interface meshes, to achieve faster convergence …
