Calibration of time features and frequency features in the time-frequency domain for improved detection and classification of seizure in newborn EEG signals
(
IEEE Computer Society
, 2012 , Conference Paper)
This paper presents new time-frequency features for seizure detection in newborn EEG signals. These features are obtained by calibrating relevant time features and frequency features in the joint time-frequency domain. The ...
Enhancing wireless networks performance through cooperative communications with interference management
(
IEEE
, 2012 , Conference Paper)
Cooperative radio communication has been proposed as an efficient technique to extend coverage and improve throughput in future wireless networks. However, its performance gain is degraded in the presence of co-channel ...
Partial relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ...
A modified modulation scheme for capacitor voltage control of renewable energy-fed grid-connected Z-Source Inverters
(
IEEE
, 2012 , Conference Paper)
An important issue in grid connection applications is boosting the limited output voltage of the renewable energy sources. Two-stage converters are most commonly employed for successful grid connection and optimum power ...
Nanocomposite Membranes of Silica and Polysulfone for Improved Gas Permeation
(
Elsevier, Ltd
, 2012 , Conference Paper)
Polysulfone-Silica mixed matrix hybrid membranes have been prepared by incorporating silicon dioxide nanoparticles with average particle size of 136 nm. Two types of polysulfone-silica nanocomposite membranes were prepared ...
Investigating the Relationship Between Professional Development and Student-Centered Learning Environments in Qatari Math and Science Elementary Classrooms
(2012 , Conference Paper)
While considerable study of the organizational structures and outcomes of Qatari educational reform in Education for a New Era initiatives has been planned and implemented (see Rand, 2007), little attention has been placed ...
A framework for condition-based maintenance scheduling
(
IEEE
, 2012 , Conference Paper)
This paper presents a general framework for planning and optimizing Condition-Based Maintenance scheduling. We assume that the hazard function depends, not only on time, but also on the system state which degrades over ...
A multi-modal face and signature biometric authentication system using a max-of-scores based fusion
(
Springer
, 2012 , Conference Paper)
Face and signature based multimodal biometric systems are often required in various areas, such as banking biometric systems and secured mobile phone operating systems, among others. Our system combines these two biometric ...
Audio-visual feature fusion for speaker identification
(
Springer
, 2012 , Conference Paper)
Analyses of facial and audio features have been considered separately in conventional speaker identification systems. Herein, we propose a robust algorithm for text-independent speaker identification based on a decision-level ...
