Comparison of Frequency Bands Using Spectral Entropy for Epileptic Seizure Prediction
(Universidad de Belgrano - Facultad de Ingeniería y Tecnología Informática - Proyectos de Investigación, 2013)
Under the hypothesis that the uncontrolled neuronal synchronization propagates recruitingmore andmore neurons,
the aim is to detect its onset as early as possible by signal analysis.This synchronization is not noticeable ...
Omnidirectional triple-band printed dipole antenna based on a dual frequency SRRs
(IEEEUSA, 2019)
This paper presents a compact triple-band planar antenna. The prototype is based on a printed dipole which is excited with Split Ring Resonators (SRRs) as resonant elements to get three frequency bands. To validate the ...
Back extensor muscle fatigue at submaximal workloads assessed using frequency banding of the electromyographic signal
(Elsevier B.V., 2011-12-01)
Background: Changes in the mean or median frequency of the electromyographic (EMG) power spectrum are often used to assess skeletal muscle fatigue. A more global analysis of the spectral changes using frequency banding may ...

Microcalcification enhancement and classification on mammograms using the wavelet transform
(2008-11-24)
This paper presents a method to enhance microcalcifications and classify their borders by applying the wavelet transform. Decomposing an image and removing its low frequency sub-band the microcalcifications are enhanced. ...
Carrier Frequency Offset Compensation for OFDMA Systems Using Circular Banded Matrices
(Planta Piloto de Ingeniería Química, 2013-07)
Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality ...
Predicting the stop-band behaviour of finite mono-coupled periodic structures from the transmissibility of a single element
(2021-06-01)
The study of mono-coupled periodic structures has gained renewed interest by the scientific community due to the new applications of metamaterials and meta-structures. Much research has focused on the wave propagation ...
