EEG-based automatic epilepsy diagnosis using the instantaneous frequency with sub-band energies
(
IEEE
, 2011 , Conference Paper)
This paper presents a novel approach for classifying the electroencephalogram (EEG) signals as normal or abnormal. This method uses features derived from the
instantaneous frequency (IF) and energies of EEG signals in ...
Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
(
IEEE
, 2011 , Conference Paper)
The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ...
Assessment of fault-ride through capability of grid-connected brushless DFIG wind turbines
(
Institution of Engineering and Technology
, 2011 , Conference Paper)
DFIGs are reported to suffer serious reliability problems due to the presence of slip-rings, brushes and gearbox. These disadvantages encouraged several research groups to investigate the viability of employing single-frame ...
A synchronous DQ frame controller via an LCL coupled filter under unbalanced three-phase voltage supply conditions
(
IEEE
, 2011 , Conference Paper)
This paper proposes a synchronous DQ frame current controller for inverter based interfaced systems. The grid voltage may be unbalanced, possibly due to unequal line impedance. The output active and reactive powers oscillate ...
Harmonic rejection using multi-synchronous reference frame technique for CSI-based distributed generation with grid voltage distortion
(
IEEE
, 2011 , Conference Paper)
In the midst of the growing penetration of renewable energy resources and Distributed Generation (DG), power quality is one of the main concerns. Achieving low total harmonic distortion (THD) of exported current using low ...
A radon wigner ville based image dissimilarity measure
(
IEEE
, 2011 , Conference Paper)
In this paper, we introduce a radon wigner ville based image dissimilarity measure. The proposed Image distortion measure aims to combine the useful properties of the wigner ville and the directionality of the finite Radon ...
On the detection and estimation of correlated signal using circular antenna arrays
(
IEEE
, 2011 , Conference Paper)
This paper presents the design and analysis of smart antenna systems used for the detection and estimation of correlated radio signals encountered in multipath environments using circular antenna arrays. The MUSIC algorithm ...
Nonlinear fault diagnosis of jet engines by using a multiple model-based approach
(
ASME 2011 Turbo Expo: Turbine Technical Conference and Exposition, GT2011
, 2011 , Conference Paper)
In this paper, a nonlinear fault detection and isolation (FDI) scheme that is based on the concept of multiple model (MM) approach is proposed for jet engines. A modular and a hierarchical architecture is proposed which ...
Comparative evaluation of four quasi-square wave fed multiphase induction machines
(
IEEE
, 2011 , Conference Paper)
Multiphase winding structures provide induction machines with favorable fault tolerant characteristics. Medium voltage drives have also benefited from the favorable application characteristics of multiphase machines, as ...
Development of a grid connected photovoltaic power conditioning system based on flying capacitors inverter
(
IEEE
, 2011 , Conference Paper)
In an effort to utilize the solar energy effectively through power electronics converters (conditioners), a great deal of research is being carried out to meet the increasing demand for load. This paper proposes an ...
