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 ...

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 ...
