Three natural cembranoids from the Red Sea soft coral Sarcophyton glaucum namely (1S,2E,4R,6E,8R,11S,12R)-8,12-epoxy-2,6-cembradiene-4,11-diol, (1S,2E,4R,6E,8S,11R,12S)-8,11-epoxy-4,12-epoxy-2,6-cembradiene and ...
Maximum power transfer of PV-fed inverter-based distributed generation with improved voltage regulation using flywheel energy storage systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
Fault detection and isolation of Riesz spectral systems: A geometric approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The Riesz spectral (RS) systems represent a large class of parabolic and hyperbolic partial differential equations (PDE) in infinite-dimensional systems. In this work, a fault detection and isolation (FDI) methodology for ...
Improved characterization of HRV signals based on instantaneous frequency features estimated from quadratic time-frequency distributions with data-adapted kernels
(
Elsevier Ltd
, 2014 , Article)
The analysis of heart rate variability (HRV) provides a non-invasive tool for assessing the autonomic regulation of cardiovascular system. Quadratic time-frequency distributions (TFDs) have been used to account for the ...
Analysis of local time-frequency entropy features for nonstationary signal components time supports detection
(
Elsevier Inc.
, 2014 , Article)
Identification of different specific signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This can be done by applying the local time-frequency-based Rényi ...
Indirect field oriented control of five-phase induction motor based on SPWM-CSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Three-phase current source inverter (CSI)-based induction motor (IM) drives are attractive in MV applications since they feature a simple inverter structure, a lower switching dv/dt, and a reliable short circuit protection. ...

Purpose: To conduct a cost analysis, a narrow cost-utility study, for upper respiratory tract infection medications in University Sans Malaysia's clinics. Methods: Retrospective analysis was done for all medical claims of ...
Four-switch three-phase SEPIC-based inverter
(
IEEE
, 2014 , Article)
Four-switch three-phase (FSTP) inverter has been proposed as an innovative inverter design to reduce the cost, complexity, size, and switching losses of the DC-AC conversion system. Traditional FSTP inverter usually operates ...
