A multi-level conceptual data reduction approach based on the Lukasiewicz implication
(
Elsevier Science Inc
, 2003 , Article)
Starting from fuzzy binary data represented as tables in the fuzzy relational database, in this paper, we use fuzzy formal concept analysis to reduce the tables size to only keep the minimal rows in each table, without ...
Non-linear simulation of controller for longitudinal control augmentation system of F-16 using numerical approach
(
Elsevier Inc
, 2003 , Article)
The non-linear simulation of controller for automatic flight control system is an essential part of the complete control design process. After using the linear approach in the design and simulation of the controller (control ...

Chronostratigraphy and geochemical characterization of volcanic rocks from the Hormuz Complex: Constraints from the Halul Island, The State of Qatar
(
sultan qaboos university
, 2003 , Article)
Geochemical and Sr-Nd isotopic data are reported for volcanic rocks in the Hormuz Complex, Halul Island, Eastern Qatar. Two groups of volcanic rocks are distinct in their geochemical characteristics. Group 1 samples have ...
Improvement of the DSATUR algorithm for graph coloring
(
Arabian Gulf University
, 2003 , Article)
In this paper we discuss the deterministic Brelaz's DSATUR algorithm for graph coloring. We propose a simple modification that improves the performance of the algorithm. This modification consists of assigning the color ...
Activation and stabilization of gallium arsenide anode in an aqueous photoelectrochemical cell
(
Elsevier
, 2003 , Article)
The formation of a porous layer on the surface of gallium arsenide anode, n-GaAs, increases photogenerated currents significantly. This layer was formed as a result of an anodic polarization of illuminated n-GaAs in acidified ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
Elsevier
, 2003 , Article)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
Park's transformation application for power system harmonics identification and measurements
(
Taylor & Francis
, 2003 , Article)
This paper presents the application of Park's transformation for identifying and measuring power system harmonics. One of the advantages of the proposed technique is that it does not need a model for the harmonics components ...
Two digital filtering algorithms for fast estimation of symmetrical components in a power system: A static estimation approach
(
Elsevier
, 2003 , Article)
This paper presents the application of two digital filters working together for fast estimation of power systems symmetrical components. The three-phase unbalanced system is transformed to two phases using α–β-transformation. ...
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
(
Elsevier
, 2003 , Article)
The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
