Propagation of modified Bessel-Gaussian beams in turbulence
(Elsevier Sci Ltd, 2008)
We investigate the propagation characteristics of modified Bessel-Gaussian beams traveling in a turbulent atmosphere. The source beam formulation comprises a Gaussian exponential and the summation of modified Bessel ...
Adsorption behavior of congo red from an aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 2008)
In this study, a reactive fibrous adsorbent was prepared through the grafting of 4-vinyl pyridine monomer onto poly(ethylene terephthalate) (PET) fibers for the removal of Congo red (CR) dye from an aqueous solution with ...
Comparison of MLP neural network and neuro-fuzzy system in transcranial doppler signals recorded from the cerebral vessels
(Springer, 2008)
Transcranial Doppler signals recorded from cerebral vessels of 110 patients were transferred to a personal computer by using a 16 bit sound card. Spectral analyses of Transcranial Doppler signals were performed for determining ...
The tricriteria flowshop scheduling problem
(Springer London Ltd, 2008)
Multicriteria flowshop scheduling problems have been one of the most attractive subjects in recent years. In the multicriteria flowshop scheduling literature, a very limited number of studies have been performed on problems ...
Channel estimation based on adaptive neuro-fuzzy inference system in OFDM
(Ieice-Inst Electronics Information Communications Eng, 2008)
In this letter we purpose adaptive neuro-fuzzy inference system (ANFIS) for channel estimation in orthogonal frequency division multiplexing (OFDM) systems. To evaluate the performance of this estimator, we compare the ...
Comparing efficiencies of genetic crossover operators for one machine total weighted tardiness problem
(Elsevier Science Inc, 2008)
In this study, the well-known one machine problem with the performance criterion of minimizing total weighted tardiness is considered. This problem is known to be NP-hard, and consists of one machine and n independent jobs. ...
Examination of static and 50 Hz electric field effects on tissues by using a hybrid genetic algorithm and neural network
(Wiley, 2008)
The effects of electric fields on tissue are the main subject of many investigations. The importance of this subject comes from the electrical properties of the cell membrane and its sensitivity to changes in electrical ...
Experimental investigation of the effect of grading characteristics on the liquefaction resistance of various graded sands
(Elsevier Science Bv, 2008)
The liquefaction susceptibility of various graded fine to medium saturated sands are evaluated by stress controlled cyclic triaxial laboratory tests. Cyclic triaxial tests are performed on reconstituted specimens having ...
Sea water effect on pinned joint glass fibre composite materials
(Elsevier Sci Ltd, 2008)
The effect of sea water on the bearing strength behavior of the woven glass fibre composite has been investigated experimentally. The ratio of the edge distance to the pin diameter (E/D), and the ratio of the specimen width ...
A bicriteria flowshop scheduling with a learning effect
(Elsevier Science Inc, 2008)
In many situations, a worker's ability improves as a result of repeating the same or similar tasks; this phenomenon is known as the learning effect. In this paper the learning effect is considered in a two-machine flowshop. ...
