Passive Noise Filtering by Cellular Compartmentalization [PDF]

open access: yesCell, 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.

Passive hybrid filter for varying rectifier loads [PDF]

open access: yes, 2005
Shunt passive filter suffers from inherent problem of getting into series and parallel resonance with power system components besides its inability to operate for diode rectifier fed load with large DC smoothing capacitor.

Interferometric time division FBG interrogator and multiplexer with static, dynamic, and absolute wavelength measurement capabilities [PDF]

open access: yes, 2012
We report on the design and preliminary testing of an interferometric interrogator capable of large-scale time-division multiplexing of FBG sensors. The scheme employs a passive algorithm for phase demodulation, allowing changes in FBG sensor reflected ...

Doppler Frequency Estimation for a Maneuvering Target Being Tracked by Passive Radar Using Particle Filter

open access: yesJournal of Communications Software and Systems, 2020
In this paper, we estimate Doppler frequency of a maneuvering target being tracked by passive radar using two types of particle filter, the first is “Maximum Likelihood Particle Filter” (MLPF) and the second is “Minimum Variance Particle filter” (MVPF ...

Inherent Characteristics Analysis and Optimal Application Scenarios of Type-C Damped Filter

open access: yesZhongguo dianli, 2023
Passive filter is extensively used in new power systems because of its mature technology and low cost, and two types of high pass (HP) filters, i.e. the second-order HP filter and type-c damped filter, are widely used for harmonic treatment However, the ...
