Study of Multiple ASE-Noise Effects and A Filtering Solution For Soliton Propagation Through Optical Fibers
… to acceptable levels far beyond that of non-filtered systems. An approach implementing a modification to the sliding-frequency filter method has demonstrated a great potential towards separating the noise components in a soliton transmission system. Previous experiments included the use of an …

Optimal estimation of ionosphere-induced group delays of global positioning satellite signals during launch, orbit and re-entry
… group delay. In the past, a single-state, dual-frequency filter has been used to estimate the ionospheric delay for authorized users. Although sufficient for terrestrial receivers for which the ionospheric delay changes very slowly, such a filter is inadequate for space-based missions in which a …

Ultrasonic Methods to Measure Shear Wave Velocity and Absorption for Tissue Viscoelasticity Characterization
… the temporal domain analysis, and temporal frequency filter was used to reduce the undesired motions. In addition, the measurement configuration to minimize the diffraction effect on the SW measurement was investigated. Furthermore, a numerical method to compensate the diffraction effect was …

Identifying, Relating, Consisting and Querying Large Heterogeneous RDF Sources
… K Characters, in which is based in two nested filters, (1) First Frequency Filter and (2) Hash Intersection filter, that allows discarding candidates before calculating the actual similarity value, thus giving a considerable performance gain, allowing to build a LOD Dataset Relation Index, in …

Design of High-Density Filter Building Blocks for SiC-based Three-Phase Power Converters
… such as DC-link capacitors and line harmonic filters. Unfortunately, with faster switching speeds and high slew rates, the common-mode (CM) and differential-mode (DM) conducted emissions interference (EMI) noise is worsened. The effects are manifested at the utility interface with grid-tied …
