Effect Of Learner-centered Professional Development On Teaching Behaviors In Qatari Elementary Math And Science Classrooms
(
QScience
, 2014 , Conference Paper)
In late 2002, Qatar established key elements of educational reform, known as "Education for a New
Era", including curriculum standards, emphasis on problem-solving through student-centered teaching;
standards-based ...
Exact SINR analysis of OFDM systems under joint Tx/RX I/Q imbalance
(
IEEE
, 2013 , Conference Paper)
The direct-conversion architecture used for Orthogonal Frequency Division Multiplexing (OFDM) systems suffers from intercarrier interference (ICI) between image subcarriers in each OFDM symbol due to I/Q imbalance between ...
Parameter Estimation of Biological Phenomena Modeled by S-systems: An Extended Kalman Filter Approach
(
IEEE
, 2011 , Conference Paper)
Recent advances in high-throughput technologies for biological data acquisition have spurred a broad interest
in the development of mathematical models for biological phenomena. S-systems, which offer a good compromise ...
Adaptive Network Coding over Cognitive Relay Networks
(
IEEE
, 2013 , Conference Paper)
We consider network coded cooperation for cognitive relay networks. The primary system comprises multiple sources and multiple destinations, whereas the secondary system comprises multiple sources, multiple relays and a ...
Energy Efficient Cross-Layer Design for Wireless Body Area Monitoring Networks in Healthcare Applications
(
IEEE
, 2013 , Conference Paper)
Growing number of patients with chronic diseases requiring constant monitoring has created a major impetus to developing scalable Body Area Sensor Networks (BASNs) for remote health applications. In this paper, to anatomize, ...
Fault Tolerance of Stator Turn Fault for Three Phase Induction Motors Star-Connected Using Artificial Neural Network
(
IEEE
, 2013 , Conference Paper)
This paper proposes the possibility of developing incipient fault diagnosis and remedial operating strategies, which enable a fault tolerant induction motor star-connected winding with neutral point earthed through a ...
ARCS-based tactics to improve students' motivation in computer programming course
(
IEEE
, 2015 , Conference Paper)
Most students find computer programming difficult subject, which frustrates them and affects their performance. In this paper, we present our experience of using ARCS model to improve students' motivation when learning ...
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 ...
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 ...
Time-Frequency Characterization of Tri-Axial Accelerometer Data for Fetal Movement Detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a significant problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity and its well-being. Using data acquired by accelerometry sensors, we ...
