On the signal contribution function with respect to different norms
(John Wiley & Sons Ltd, 2021-07-10)
The signal contribution function (SCF) in multivariate curve resolution evaluates signal portions of specific components either in absolute or in relative form related to the integrated signal of all components. In 1999, ...
Impact of number of channels on signal transmission in elastic optical network
(2018-01-01)
In this paper, the impact of the number of channels on the performance of elastic optical networks (EONs) is examined considering a multilevel modulation format and coherent transmission. Network design parameters such as ...
Comparison of Frequency Bands Using Spectral Entropy for Epileptic Seizure Prediction
(Hindawi Publishing Corporation, 2013-05)
Under the hypothesis that the uncontrolled neuronal synchronization propagates recruiting more and more neurons, the aim is to detect its onset as early as possible by signal analysis. This synchronization is not noticeable ...
Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...

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 ...
How noise affects the band boundaries in multivariate curve resolution
(Elsevier Science, 2022-05)
Three models are compared regarding the estimation of the boundaries of the range of feasible bilinear solutions brought about by rotational ambiguity in the presence of noise. A two-component system having significant ...
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 ...
