A template-free approach for waveform extraction of gravitational wave events
Scientific Reports, 2021 We develop a general data-driven and template-free method for the extraction of event waveforms in the presence of background noise. Recent gravitational-wave observations provide one of the significant scientific areas requiring data analysis and ...

Noise radar technology: Pseudorandom waveforms and their information rate [PDF]
2014 15th International Radar Symposium (IRS), 2014 The well-known LPI (Low Probability of Intercept) and antispoofing capabilities of some radar waveforms as well some other desirable feature such as a low sidelobes level of their autocorrelation function can be enhanced by “tailored” pseudo-random sequences, whose phase is made up by a deterministic part plus a variable random term.

On the anti‐intercept features of noise radars
IET Radar, Sonar & NavigationRobustness against Electronic Warfare/Electronic Defence attacks represents an important advantage of Noise Radar Technology (NRT). An evaluation of the related Low Probability of Detection (LPD) and of Intercept (LPI) is presented for Continuous ...

Photoacoustics Waveform Design for Optimal Signal to Noise Ratio
Symmetry, 2022 Time-frequency analysis in waveform engineering can be applied to many detection and imaging systems, such as radar, sonar, and ultrasound to improve their Signal-to-Noise Ratio (SNR). Recently, photoacoustic imaging systems have attracted researchers’ attention.

Advanced Engineering Materials, EarlyView.This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Studies on 1D Electronic Noise Filtering Using an Autoencoder
KnowledgeAutoencoders are neural networks that have applications in denoising processes. Their use is widely reported in imaging (2D), though 1D series can also benefit from this function.
