Habituation as optimal filtering [PDF]
iScienceSummary: Habituation, the reduction of responding to repetitive stimuli, is often conceptualized as a kind of attentional filter, amplifying salient signals at the expense of non-salient signals.

Optimal Filtering Methods to Structural Damage Estimation under Ground Excitation [PDF]
The Scientific World Journal, 2013 This paper considers the problem of shear building damage estimation subject to earthquake ground excitation using the Kalman filtering approach. The structural damage is assumed to take the form of reduced elemental stiffness.

Gaussian Filter for Brain SPECT Imaging
Innovative Biosystems and Bioengineering, 2022 Background. The presence of a noise component on 3D images of single-photon emission computed tomography (SPECT) of a brain significantly distorts the probability distribution function (PD) of the radioactive count rate in the images.
