Particle filtering for passive fathometer tracking [PDF]
The Journal of the Acoustical Society of America, 2011 Seabed interface depths and fathometer amplitudes are tracked for an unknown and changing number of sub-bottom reflectors. This is achieved by incorporating conventional and adaptive fathometer processors into sequential Monte Carlo methods for a moving vertical line array.

Passive Loop Filter Assistance for CTSDMs [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2017 This brief presents a power reduction technique for continuous time sigma–delta modulators (CTSDMs). The approach consists of two elements. First, a passive low-pass filter is added in front of the modulator’s loop filter to reduce the high frequency components in the loop.

Passive Noise Filtering by Cellular Compartmentalization [PDF]
Cell, 2016 Chemical reactions contain an inherent element of randomness, which presents itself as noise that interferes with cellular processes and communication. Here we discuss the ability of the spatial partitioning of molecular systems to filter and, thus, remove noise, while preserving regulated and predictable differences between single living cells.
