Investigation of the use of TiO2 doped with metal ions in water disinfection
(
IWA Publishing
, 2010 , Article)
This research was conducted to improve titanium dioxide by transition metal doping using cooper. Sol gel method was used to prepare metal doped TiO 2. Titanium isopropoxide and commercial TiO2 P25 were employed as catalyst ...
R-wave detection: A comparative analysis of four methods using newborn piglet ECG
(
IEEE
, 2010 , Conference Paper)
In the electrocardiograph (ECG), R-wave is the positive upward deflection in the QRS complex which represents the depolarization of both left and right ventricles. Accurate detection of the R-wave peaks in the ECG plays a ...
Error analysis associated with uniform Hermite interpolations of bandlimited functions
(
Korean Mathematical Society
, 2010 , Article)
We derive estimates for the truncation, amplitude and jitter type errors associated with Hermite-type interpolations at equidistant nodes of functions in Paley-Wiener spaces. We give pointwise and uniform estimates. Some ...
Academic procrastination and its relation to motivation and self-efficacy: The case of Qatari primary school students
(
Common Ground Publishing
, 2010 , Article)
Academic procrastination seems to be prevalent in academic settings where students tend to delay their tasks without valid excuses, submitting their assignments until the last minute before the deadlines. Research has shown ...
Detection of neonatal seizure using multiple filters
(
IEEE
, 2010 , Conference Paper)
It is often impossible to accurately differentiate between seizure and non-seizure related activities in irifants based on clinical manifestations alone. The electroencephalogram (EEG) is therefore the best tool available ...
Capacitor voltage balancing using redundant states of space vector modulation for five-level diode clamped inverters
(
IEEE
, 2010 , Article)
A redundancy balancing technique for the five-level diode-clamped inverter is presented, which balances the four dc-link capacitor voltages at high modulation index and high power factor. The technique is based on dividing ...

Credit default swap pricing using artificial neural networks
(2010 , Conference Paper)
The credit derivatives market has experienced unprecedented growth over the past few years. As such, there is a growing interest in tools for pricing the most prominent credit derivative, the credit default swap. In this ...
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 ...
