Compressive Sensing for Inverse Scattering
(2008-06-30)
Compressive sensing is a new field in signal processing and applied mathematics. It allows one to simultaneously sample and compress signals which are known to have a sparse representation in a known basis or dictionary ...
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 ...
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 ...
Monitoring of Self-Excited Vibration in Grinding Process Using Time-Frequency Analysis of Acceleration Signals
(Ieee, 2018-01-01)
Grinding is a finish manufacturing process for high precision parts. As the part has high value added at this stage, anomalies and defects are unacceptable. Self-excited vibration or just chatter is an undesirable and ...
Tool condition monitoring of single-point dressing operation by digital signal processing of AE and AI
(Elsevier B.V., 2018-01-01)
This work aims at determining the right moment to stop single-point dressing the grinding wheel in order to optimize the grinding process as a whole. Acoustic emission signals and signal processing tools are used as primary ...
Signal-to-noise ratio constrained feedback control: discrete-time robust stability analysis
(IET Control Theory and Applications, 2020)
METHOD AND APPARATUS FOR ANALYSING BIOMEDICAL SIGNALS
A method of analysing biomedical signals, and particularly electrocardiograph signals that have been received over a period of time, using data processing equipment. The method comprises storing data representing the ...
