Information Flow in Coupled Nonlinear Systems: Application to the Epileptic Human Brain
Shivkumar Sabesan,K. Narayanan,Awadhesh Prasad,Leonidas D. Iasemidis,Andreas Spanias,K. Tsakalis +5 more
TL;DR: Improvements in the selection of parameters for the estimation of TE are suggested that significantly enhance its accuracy and robustness in identifying the direction of information flow and quantifying the level of interaction between observed data series from coupled systems.
Journal ArticleDOI
Non-Linear Distributed Average Consensus Using Bounded Transmissions
TL;DR: A distributed average consensus algorithm in which every sensor transmits with bounded peak power results in slower convergence compared to the linear consensus algorithm based on the Laplacian heuristic.
Journal ArticleDOI
On-line signal processing using J-DSP
Andreas Spanias,Atti Venkatraman S,Antonia Papandreou-Suppappola,Khawza I. Ahmed,M. Zaman,Thrassos Thrasyvoulou +5 more
TL;DR: Statistical analysis of the pre/post assessment data revealed that the effect of student involvement and the student learning has been enhanced by using J-DSP.
Proceedings ArticleDOI
Advanced concepts in time-frequency signal processing made simple
TL;DR: In this article, the authors present the Java software module for the spectrogram implementation together with the associated programming environment to introduce to students the advanced concepts of TFRs at an early stage in their education without requiring a rigorous theoretical background.
Proceedings ArticleDOI
J-DSP-C, a control systems simulation environement: labs and assessment
TL;DR: This paper presents various on-line computer laboratory exercises and related assessment results for Java-Digital Signal-Processing-Controls (J-DSP-C).
