Time-frequency and time-scale analysis of Barkhausen noise signals
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2009)
Carrying out information about the microstructure and stress behaviour of ferromagnetic steels, magnetic Barkhausen noise (MBN) has been used as a basis for effective non-destructive testing methods, opening new areas in ...
Digital signal processing for self-vibration monitoring in grinding: A new approach based on the time-frequency analysis of vibration signals
(2019-10-01)
The occurrence of chatter can generate parts outside the dimensional and geometric tolerances or even cause irreversible damage, such as changes to the hardness and surface roughness of the ground part. The objective of ...
Signals in Communication Engineering History
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper is a study of various electric signals, which have been employed throughout the history of communication engineering in its two main landmarks: the telegraph and the telephone. The signals are presented in their ...
Intelligent real-time traffic signal control based on a paraconsistent logic program EVALPSN
(Springer, 2003-01-01)
In this paper, we introduce an intelligent real-time traffic signal control system based on a paraconsistent logic program called an EVALPSN (Extended Vector Annotated Logic Program with Strong Negation), that can deal ...
Baseline-free Damage Imaging Algorithm using Spatial Frequency Domain Virtual Time Reversal
(2021-01-01)
Structural health monitoring techniques are widely used in industry applications to guarantee the integrity of several types of components. This article proposes a baseline-free damage imaging algorithm based on Spatial ...
Wnt-regulated dynamics of positional information in zebrafish somitogenesis
(Company Of Biologists, 2014-03)
How signaling gradients supply positional information in a field of moving cells is an unsolved question in patterning and morphogenesis. Here, we ask how a Wnt signaling gradient regulates the dynamics of a wavefront of ...
Time - Frequency analysis of biosignals

Feature extraction using frequency spectrum and time domain analysis of vibration signals to monitoring advanced ceramic in grinding process
(Inst Engineering Technology-iet, 2019-01-01)
New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...
Nearly symmetric orthogonal wavelets for time-frequency-shape joint analysis: Introducing the discrete shapelet transform's third generation (DST-III) for nonlinear signal analysis
(2021-06-01)
This article introduces the third generation of an interesting tool created for time-frequency-shape (TFS) joint analysis. Called Discrete Shapelet Transform (DST-III), it improves both its predecessors, i.e., DST-I and ...
Pedestrian signalization and the risk of pedestrian-motor vehicle collisions in Lima, Peru
(Elsevier, 2014)
Safe walking environments are essential for protecting pedestrians and promoting physical activity. In Peru, pedestrians comprise over three-quarters of road fatality victims. Pedestrian signalization plays an important ...
