R-wave detection: A comparative analysis of four methods using newborn piglet ECG
(
IEEE
, 2010 , Conference Paper)
In the electrocardiograph (ECG), R-wave is the positive upward deflection in the QRS complex which represents the depolarization of both left and right ventricles. Accurate detection of the R-wave peaks in the ECG plays a ...
Ordered clustering: A way to simplify analysis of multichannel signals
(
IEEE
, 2010 , Conference Paper)
We describe here new possibilities offered by a
clustering method routinely used by many petroleum
companies and which could be used in other
applications where analysis of multichannel signals has
a significant role ...
Detection of neonatal seizure using multiple filters
(
IEEE
, 2010 , Conference Paper)
It is often impossible to accurately differentiate between seizure and non-seizure related activities in irifants based on clinical manifestations alone. The electroencephalogram (EEG) is therefore the best tool available ...
Investigation of inter-line dynamic voltage restorer with virtual impedance injection
(
IEEE
, 2010 , Conference Paper)
The Inter-Line Dynamic Voltage Restorer (IDVR) consists of several voltage source inverters connected to different independent distribution feeders with common dc bus. When one of the inverters compensates for voltage sag ...
An active damping technique for a current source inverter employing a virtual negative inductance
(2010 , Conference Paper)
A grid connected CSI requires a CL filter stage. In this work, the isolation transformer leakage inductance constitutes this filter inductance. This CL filter is lightly damped for efficiency constraints. Hence, it is ...
Inverter-based versus synchronous-based distributed generation; Fault current limitation and protection issues
(
IEEE
, 2010 , Conference Paper)
The contribution of distributed generation (DG) to network fault levels depends heavily on the technology employed. In the case of directly connected rotating machines the fault behavior is well established; with synchronous ...
New voltage regulation techniques for low voltage radial feed PWM inverter based distributed networks
(2010 , Conference Paper)
Grid voltage rise problems occur, especially at light loads, due to the proliferation of distributed generation. Two techniques are proposed for regulating the voltage in low voltage radial networks when inverter based ...
Cognitive relaying in wireless sensor networks: Performance analysis and optimization
(
IEEE
, 2010 , Conference Paper)
The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ...
Preparing and educating the Arab Qatari engineer of 2030
(
American Society for Engineering Education
, 2010 , Conference Paper)
This paper addresses the issue of adapting Engineering Education to a changing situation in Qatar, a small country that is part of the Arab Gulf Cooperation Council. It presents the framework for a national project planned ...
A signal combining technique based on channel shortening for cooperative sensor networks
(
IEEE
, 2010 , Conference Paper)
The cooperative relaying process needs proper coordination among the communicating and the relaying nodes. This coordination and the required capabilities may not be available in some wireless systems, e.g. wireless sensor ...
