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 the Learning Environment in Higher and Lower Performing "Education for a New Era" Schools
(2010 , Conference Paper)
Recently, Qatar established key elements of educational reform including curriculum standards; emphasis on student-centered teaching; charter school establishment; standards-based assessment; English as the language of ...
حق المرأة القطرية العاملة فى الاجازات فى قانوني العمل والموارد البشرية القطريين - دراسة مقارنة
(
جامعة الإسكندرية - كلية الحقوق
, 2010 , Conference Paper)
ينص المشرع القطري فى دستور قطر الدائم على أن النشاط الاقتصادي يقوم على القطاعين العام، والخاص ( م 28 من دستور قطر)، ونص كذلك على أن العلاقة بين العمال وأرباب العمل تقوم على العدالة الاجتماعية ( م 30 من دستور قطر)، ونظرا ...
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 ...
Utility-based uplink scheduling algorithm for enhancing throughput and fairness in relayed LTE networks
(
IEEE
, 2010 , Conference Paper)
Relaying is one of the key techniques considered by the 3GPP LTE-Advanced as part of 4G cellular technologies, aiming to increase the coverage and capacity of the network especially for the edge nodes. In this work, we ...
