Hybrid fault detection and isolation strategy for non-linear systems in the presence of large environmental disturbances
(
Institution of Engineering and Technology
, 2010 , Article)
The problem of designing and developing a hybrid fault detection and isolation (FDI) scheme for a non-linear system that is subject to large environmental disturbances is investigated. In the proposed FDI scheme, a hybrid ...
Inverter-based versus synchronous-based distributed generation; Fault current limitation and protection issues
(
IEEE
, 2010 , Conference Paper)
The contribution of distributed generation (DG) to network fault levels depends heavily on the technology employed. In the case of directly connected rotating machines the fault behavior is well established; with synchronous ...
A Nonlinear Model of Newborn EEG with Nonstationary Inputs
(
Springer US
, 2010 , Article)
Newborn EEG is a complex multiple channel
signal that displays nonstationary and nonlinear characteristics.
Recent studies have focussed on characterizing the
manifestation of seizure on the EEG for the purpose of
automated ...
Real Time Digital Feedback Control for VFD fed by cascaded multi-cell inverter
(
IEEE
, 2010 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a Real Time Digital Feedback Controller (RTDFBC) combined ...
Multiple-view time-frequency distribution based on the empirical mode decomposition
(
Institution of Engineering and Technology
, 2010 , Article)
This study proposes a novel, composite time-frequency distribution (TFD) constructed using a multiple-view approach. This composite TFD utilises the intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD) ...
On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
(
IEEE
, 2010 , Conference Paper)
Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ...
A comparative analysis of experimental and numerical investigations of composite tubes under axial and lateral loading
(2010 , Article)
Quasi-static tests are performed in order to determine the crash behavior of composite tubes. The specimens are made from woven fiber carbon/epoxy. The crash experiments show that the tubes crushed in a progressive manner ...
Estimation of highly selective channels for downlink LTE systemby a robust neural network
(
Hamad bin Khalifa University Press (HBKU Press)
, 2010 , Conference Paper)
In this paper we propose a robust channel estimator for the downlink of a Long Term Evolution (LTE) system using a highly selective neural network. This method uses the information provided by the reference signals to ...
Q-Map Application for Enrichment of a Mobile Directory Assistance Service
(
NCCIT 2010
, 2010 , Article)
The project described in this paper involves designing and developing a mobile map application, called the Qatar Map (Q-Map), which supports a telephone directory assistance service that runs over the terrestrial cellular ...
Accurate PpT Data for Methane from (300 to 450) K up to 180 MPa
(
American Chemical Society
, 2010 , Article)
This paper reports PFT data measured with a high-pressure, single-sinker, magnetic-suspension densimeter (MSD)
from (300 to 450) K up to 180 MPa. Our MSD technique yields accurate data, with less than 0.05 % relative
