Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ...
Elimination of reverse recovery effects associated with CoolMOS devices employing current source inverter topology
(
IET
, 2012 , Conference Paper)
MOSFET transistors are continuously being an essential part of power electronic converters due to their low switching losses at high switching frequencies. However, the traditional power MOSFET suffers from a relatively ...
Directed graph-based wireless EEG sensor channel selection approach for cognitive task classification
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Wireless electroencephalogram (EEG) sensors have been successfully applied in many medical and computer brain interface classifications. A common characteristic of wireless EEG sensors is that they are low powered devices, ...
Axial pull-out response of a small-scale concrete pile subjected to cyclic thermal loading in sand
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
Energy piles support structural loads and exchange heat with surrounding soils using closed-loop ground source heat pump (GSHP) systems. A GSHP connected to an energy pile operates in cycles where it functions for a period ...
A novel two-step metal oxide - Metal sulfate water splitting cycle for the production of solar hydrogen
(
AIChE
, 2015 , Conference Paper)
This paper reports the thermodynamic analysis of solar H2 production via two-step thermochemical Strontium oxide - Strontium Sulfate (SO-SS) water splitting cycle. The first step belongs to the exothermic oxidation of SrO ...
Hydrate surface area measurements during dissociation using dynamic 3d synchrotron computed tomography
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Availability of natural hydrates and ongoing rise in demand for energy, motivated researchers to consider hydrates as a potential energy source. Prior to gas production operations from hydrate-bearing sediments, hydrate ...
A five-phase induction machine model using multiple DQ planes considering the effect of magnetic saturation
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase phase induction machines are usually modeled using multiple dq planes, where complete decoupling between these sequence planes is usually assumed. This assumption may be accepted if the magnetic circuit is assumed ...
Enhancing student learning in chemical engineering design via role play and enquiry guided learning: A case study from Qatar
(2012 , Conference Paper)
Plant design is the capstone design course taken in the senior year of a chemical engineering students at Qatar University and is spread over two semesters (Plant Design I and Plant Design II). The course content, delivery ...
Computer aided diagnosis system based on machine learning techniques for lung cancer
(2012 , Conference Paper)
Cancer is a leading cause of death worldwide. Lung cancer is a type of cancer that is considered as one of the most leading causes of death globally. In Malaysia, it is the 3rd common cancer type and the 2nd type of cancer ...
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
(
AIChE
, 2014 , Conference Paper)
In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
