Recent research in FEA has focused on improving the robustness and accuracy of various finite element methods, particularly in the context of large deformations, mesh distortion, and the analysis ...

Although simple notch, which directly removes the certain frequency components of nonlinear system input and then measures the regrowth components of nonlinear system output, is straightforward to ...

For example, it is shown that if one of the time series undergoes an amplitude distortion in a time-varying "instantaneous" nonlinear device, the covariance function after distortion is simply ...

At a macroscopic scale, techniques for inducing shear waves using an external mechanical vibration, an acoustic radiation pressure or a Lorentz force are reviewed along with imaging approaches ...

A neural code based on sequences of spikes can consume a significant portion of the brain's energy budget. Thus, energy considerations would dictate that spiking activity be kept as low as possible.

Apertures and arrays: Finite apertures, resolution, spatial sampling and arrays of discrete sensors, sidelobes and grating lobes. Beamforming: Delay-and-sum and frequency-domain beamforming, array ...
