Constructivist Multi-Access Lab Approach in Teaching FPGA Systems Design with LabVIEW
(
International Society for Engineering Education (IGIP) in cooperation with Kassel University Press GmbH
, 2013 , Article)
Embedded systems play vital role in modern
applications [1]. They can be found in autos, washing
machines, electrical appliances and even in toys. FPGAs are
the most recent computing technology that is used in ...
An automatic time-frequency procedure for interference suppression by exploiting their geometrical features
(
IEEE
, 2011 , Conference Paper)
This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville ...
Kalman filter-based time-varying cortical connectivity analysis of newborn EEG
(
IEEE
, 2011 , Conference Paper)
Multivariate Granger causality in the timefrequency
domain as a representation of time-varying cortical
connectivity in the brain has been investigated for the adult
case. This is, however, not the case in newborns as ...
Instantaneous Frequency Estimation of Multi-component Non-Stationary Signals using Multi-view Time-Frequency Distributions Based on the Adaptive Fractional Spectrogram
(
IEEE
, 2013 , Article)
This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution ...
Fast and memory-efficient algorithms for computing quadratic time–frequency distributions
(
Elsevier Inc
, 2013 , Article)
Algorithms for computing time–frequency distributions (TFDs) limit computation time by reducing numerical operations. But these fast algorithms do not reduce the memory load. This article presents four TFD algorithms to ...
Image quality metrics based multifocus image fusion
(
IEEE
, 2011 , Conference Paper)
We describe an innovative methodology for block based multifocus
image fusion in the spatial domain. The main idea is
to use blind or no reference blur metrics for image fusion applications.
Two blur quality metrics ...
A Nonlinear Model of Newborn EEG with Nonstationary Inputs
(
Springer US
, 2010 , Article)
Newborn EEG is a complex multiple channel
signal that displays nonstationary and nonlinear characteristics.
Recent studies have focussed on characterizing the
manifestation of seizure on the EEG for the purpose of
automated ...
Multiple-view time-frequency distribution based on the empirical mode decomposition
(
Institution of Engineering and Technology
, 2010 , Article)
This study proposes a novel, composite time-frequency distribution (TFD) constructed using a multiple-view approach. This composite TFD utilises the intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD) ...
An improved method for nonstationary signals components extraction based on the ICI rule
(
IEEE
, 2011 , Conference Paper)
This paper proposes an improved adaptive algorithm for components localization and extraction from a noisy multicomponent signal time-frequency distribution (TFD). The algorithm, based on the intersection of confidence ...
Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy
(
Springer
, 2011 , Article)
The time-frequency Rényi entropy provides a measure of complexity of a nonstationary multicomponent signal in the time-frequency plane. When the complexity of a signal corresponds to the number of its components, then this ...
