Time-frequency approach to radar detection, imaging, and classification
(
Institution of Engineering and Technology
, 2010 , Article)
One of the central problems in exploiting the radar data is the analysis of atime series. The problem at hand is how to extract the information present in the data and use it to its full potential. Traditionally, radar ...
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) ...
A Discontinuous PWM Method for Balancing the Neutral Point Voltage in Three-Level Inverter-Fed Variable Frequency Drives
(
IEEE
, 2008 , Article)
The paper describes a new discontinuous carrier-based pulsewidth modulation (PWM) method for use in variable frequency drives (VFD) driven by three-level inverters. The method introduces three different switching patterns ...
Power system frequency estimation based on simulated annealing. Part I: A constant frequency study
(
King Fahd University of Petroleum and Minerals
, 2003 , Article)
In this paper a new algorithm based on Simulated Annealing (SA) method is used to estimate the signal parameters of a system steady power system, having a constant frequency during data window size. The proposed algorithm ...
A novel algorithm for molecular synthesis using enhanced property operators
(
Elsevier Ltd
, 2008 , Article)
Traditionally process design and molecular design have been treated as two separate problems, with little or no feedback between the two approaches. Introduction of the property integration framework has allowed for ...
A simplified method for calculating saturated liquid densities
(
Elsevier B.V.
, 2004 , Article)
A simplification for the Nasrifar–Moshfeghian (NM) liquid density correlation has been developed. A replacement for the Mathias and Copeman temperature-dependent term with the original Soave–Redlich–Kwong equation of state ...
A systematic visual approach to molecular design via property clusters and group contribution methods
(
Elsevier Ltd
, 2008 , Article)
In this work, a new simple yet effective, systematic method to synthesize and design molecules is presented. Visualization of the problem is achieved by employing an annex to the recently developed property clustering ...
Review on the Use of Ionic Liquids (ILs) as Alternative Fluids for CO2 Capture and Natural Gas Sweetening
(
American Chemical Society
, 2010 , Article)
The capture of CO2 from flue gases derived from fossil-fueled power plants and the absorption of CO2/H2S for natural gas sweetening purposes are two relevant industrial problems closely related to very important environmental, ...
Structure-thermal expansivity relation for isotropic polyoxymethylene sheets
(
John Wiley & Sons, Ltd.
, 1994 , Article)
A detailed parametric mapping analysis of the thermal expansion coefficient for isotropic polyoxymethylene is presented. The molecular composite model has been computerized to investigate the variation of the thermal ...
Bench-scale and packed bed sorption of methylene blue using treated olive pomace and charcoal
(
Elsevier Ltd
, 2006 , Article)
A combination of olive pomace after solvent extraction and charcoal produced from the solid waste of olive oil press industry was used as an adsorbent for the removal of methylene blue (MB) dye from aqueous solutions. Batch ...
