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 ...
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 ...
Applying and evaluating architectural patterns on a stock trading case study
(
IEEE
, 2012 , Conference Paper)
Teaching architectural and design patterns is a difficult task and not easy to understand by the students as patterns are expressed at a higher abstraction level than programming language constructs or graphical UML ...
An online signature verification system for forgery and disguise detection
(
Springer
, 2012 , Conference Paper)
Online signatures are acquired using a digital tablet which provides all the trajectory of the signature as well as the variation in pressure with respect to time. Therefore, online signature verification achieves higher ...
Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...
Multiple sensor fault diagnosis for non-linear and dynamic system by evolving approach
(
2012 3rd Annual IEEE Prognostics and System Health Management Conference, PHM-2012
, 2012 , Conference Paper)
Reliability of sensor measurement is vital to assure the performance of complex and nonlinear industrial operation. In this paper, the problem of designing and development of a data-driven multiple sensor fault detection ...
Towards cost-effective maintenance of power transformer by accurately predicting its insulation condition
(2012 , Conference Paper)
Insulation resistance (IR) or Megger test has been commonly performed in both preventive and corrective maintenance activities to verify power transformers' insulation condition. Other insulation diagnosis tests such as ...
Generalized Mean Phase Coherence for asynchrony abnormality detection in multichannel newborn EEG
(2012 , Conference Paper)
Inter-hemispheric asynchrony within the multichannel recordings of newborn EEG is associated with abnormal functionality of the newborn brain. Mean Phase Coherence (MPC) as a bivariate phase synchrony measure is widely ...
