A novel multilevel carrier-based PWM-control method for GTO inverter in low index modulation region
(
IEEE
, 2006 , Article)
Gate turn offs (GTOs) have an inherent minimum ON-OFF time, which is needed for their safe operation. For GTO-based three-level or neutral-point-clamped (NPC) inverters, this minimum ON-OFF pulsewidth limitation results ...

Investigations of He <sup>+</sup> implantation and subsequent annealing effects in InP
(
Elsevier
, 2006 , Article)
The influence of 70 keV He + ion implantation and subsequent annealing of Cz-indium phosphide (InP) samples has been investigated using a slow positron beam-based Doppler broadening spectrometer. Three samples with ion ...
Self-implantation of Cz-Si: Clustering and annealing of defects
(
Elsevier
, 2006 , Article)
Observations of vacancy clusters formed in Czochralski (Cz) Si after high energy ion implantation are reported. Vacancy clusters were created by 2 MeV Si ion implantation of 1 × 10 15 ions/cm 2 and after annealing between ...
Continuous potentiometric monitoring of viagra (sildenafil) in pharmaceutical preparations using novel membrane sensors
(
Springer Nature
, 2006 , Article)
Two potentiometric sensors responsive to sildenafil citrate (SC) drug (the active component of viagra) are described, characterized, compared and used for drug assessment. The sensors are based on the use of the ion-association ...
Factors influencing determination of shale classification indices and their correlation to mechanical properties
(
Springer Verlag
, 2006 , Article)
The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ...
Power quality analysis based on fuzzy estimation algorithm: Voltage flicker measurements
(
Elsevier
, 2006 , Article)
This paper presents a method based on fuzzy linear estimation for voltage flicker measurements. The proposed algorithm uses the digitized samples of the voltage signal at the location where the power quality standards are ...
Stability analysis and charts for slopes susceptible to translational failure
(
Canadian Science Publishing
, 2006 , Article)
The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ...
