Zero-group velocity (ZGV) modes in rails are studied through simulation and experiments. Local resonances associated with ZGV modes appear as distinct, sharp peaks in the frequency amplitude spectrum, whose resonant frequencies can serve as indicators of the local structural integrity condition of the...
Routine bridge inspections in the United States are primarily conducted via visual inspection on a fixed two-year cycle. Although this strategy has generally produced a safe bridge network, a variety of research has been conducted to study enhanced inspection planning processes that could more efficiently...
Over the last two decades many researchers have focused on providing new ideas and frameworks that can help improve conventional bridge inspection practices; however, little guidance is provided for implementing these new ideas in practice. This, along with resistance to change and complexity of the...
Of all microelectromechanical systems (MEMS), regardless of application, micron-scale spacing of interleaved electrodes and high-dielectric ceramics in multilayer ceramic capacitors (MLCCs) provide exceptionally high capacitances in small volumes. This has led to MLCCs being the preferred type of capacitor...
