A set of geometrical features for writer identification
(
Springer
, 2012 , Conference Paper)
Writer identification is an important field in the forensic document examination. We propose in this paper a set of geometrical features that makes it possible to characterize writers. They include directions, curvatures ...
Modified Alamouti decoding for highly selective channels for LTE systems
(
IEEE
, 2012 , Conference Paper)
In this contribution, we propose an improvement of Alamouti coding for equalization of space-time block code multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) over highly-selective ...
Cloud-Ready Biometric System for Mobile Security Access
(
Springer
, 2012 , Conference Paper)
In this contribution, we introduce an application that allows a mobile phone to be used as a biometric-capture device for secure access to the cloud. In this application, the biometric capture and recognition are performed ...
Multilevel cascaded Z source inverter for PV power generation system
(
IEEE
, 2012 , Conference Paper)
The paper investigates the use of multilevel cascaded Z source inverter (MC-ZSI) for photovoltaic (PV) power generation system. The control of the proposed system will take into account the multilevel modulation scheme and ...
Compressed wideband spectrum sensing with correlated subband occupancy in multi-antenna cognitive radios
(2012 , Conference Paper)
In this paper, we investigate the use of multiple antennas at the cognitive radio receiver for improved wideband spectrum sensing and exploit compressed sensing to reduce the extremely high sampling rate of wideband signal. ...
QUWI: An Arabic and English handwriting dataset for offline writer identification
(
IEEE
, 2012 , Conference Paper)
This paper presents a new offline dataset called the Qatar University Writer Identification dataset (QUWI). This dataset contains both Arabic and English handwritings and can be used to evaluate the performance of offline ...
Orthogonalized partial directed coherence for functional connectivity analysis of newborn EEG
(2012 , Conference Paper)
The aim of this study is to develop a time-frequency method and test its applicability to investigating directional cortical connectivity in the newborn brain considering the effect of volume conduction. We modified ...
Design of a high-resolution separable-kernel quadratic TFD for improving newborn health outcomes using fetal movement detection
(2012 , Conference Paper)
Prior to birth, fetus health can be monitored by the variety and scale of its movements. In addition, at birth, EEG signals are recorded from at-risk newborns. Studies have shown that both fetal movements and newborn EEGs ...
Simplified generic on-line PWM technique for single phase grid connected current source inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Conference Paper)
Mandatory restrictions for a current source inverter's (CSI's) proper operation, like continuity of the DC link current, complicate the corresponding PWM generation especially in the case of single phase systems. Classical ...
A coaxial magnetic gearbox with magnetic levitation capabilities
(
IEEEIEEE
, 2012 , Conference Paper)
Magnetic gearboxes (MGBs) are now a powerful alternative to their conventional mechanical counterparts in terms of reduced maintenance requirements, improved reliability, tolerance to mechanical inaccuracies, and inherent ...
