Facilitating Teachers in Developing Online PBL Courses
(
IEEE
, 2013 , Conference Paper)
Developing a sound online problem-based learning (PBL) course plan is difficult because teachers need comprehensive PBL and technical knowledge. This paper proposes a model-driven approach to develop a PBL authoring tool ...
Hybrid thin-films of graphene materials and metallic nanowires for next generation transparent electrodes
(
Optics InfoBase
, 2013 , Conference Paper)
We report advances in the fabrication and characterization of transparent conductive electrodes based on thin-films of metallic nanowires (copper and silver) encapsulated with graphene, graphene oxide, and reduced graphene ...
Modified QR-D and MMSE PMI selection technique for MIMO closed loop spatial multiplexing in LTE/LTE-advanced
(2013 , Conference Paper)
Limited feedback closed-loop spatial multiplexing evolved as an attractive technique during the development of Multi Input Multi Output (MIMO) in Long Term Evolution (LTE). Spatial multiplexing involves transmitting ...
Novel cooperative communication schemes with interference management for multi-user wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Cooperative communication is a promising technique for future wireless networks. It can be used in improving communication reliability, and enhancing power and spectrum efficiency. However, its performance gain degrades ...
Performance of a five-phase boost inverter-fed submersible induction machine
(2013 , Conference Paper)
An electrical submersible pump (ESP) motor is preferably fed from a low voltage variable-frequency drive (VFD) followed by a step-up transformer. The motor and drive connection through a long feeder usually causes over ...
Systolic architecture for hardware implementation of two-dimensional non-separable filter-bank
(
IEEE
, 2013 , Conference Paper)
In this paper, we present an efficient poly-phase decomposition scheme for implementation of 2-D non-separable filter bank. Poly-phase decomposition scheme offers multiplexing of filter bank computations or/and reduce the ...

(2013 , Conference Paper)
Recent developments in semiconductor technology enabled developing converters with ultra high switching frequency to achieve high power densities which increased the complexity of designing optimized gate drive circuits. ...
An improved predictive control approach for Multilevel Inverters
(
IEEE
, 2013 , Conference Paper)
This paper proposes a flexible predictive control strategy for flying capacitors based Multi-Level Inverters (MLIs). The proposed controller, applied for a Flying Capacitors Inverter (FCI) and a Modular Multilevel Converter ...
Interference management schemes with general order statistics and interference constraint for multi-user cooperative wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper, two cooperative communications schemes with interference management are proposed for multiuser wireless networks. The first scheme (Interference Constraint based Relay Selection (ICRS)) maximizes the received ...
