the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولThe Polyakov Loop and the Eigenvalues of the Dirac Operator
Aiming at the link between confinement and chiral symmetry the Polyakov loop represented as a spectral sum of eigenvalues of the Dirac operator was subject of recent studies. We analyze the volume dependence as well as the continuum behavior of this quantity for quenched QCD using staggered fermions. Furthermore, we present first results using dynamical configurations.
متن کاملPolyakov loop, Quasiparticles and QCD Phase Diagram
QCD thermodynamics has been the subject of intense investigations in recent years. In order to interpret corresponding lattice QCD results the Polyakov-loop extended Nambu Jona-Lasinio (PNJL) model is a promising field theoretical quasiparticle model [1, 2, 3, 4] combining the two principal non-perturbative features of lowenergy QCD: confinement and spontaneous chiral symmetry breaking. In the ...
متن کاملPhase Diagram and Pion Modes of the Neutral Nambu-jona Lasinio Model with the Polyakov Loop
The study of strong interactions by means of effective models, which are simpler to manage than Quantum Chromodynamics (QCD), is nowadays very popular. Among the various effective models of QCD the Nambu-Jona Lasinio model (NJL) is widely used since it allows for a simple and non perturbative discussion of chiral symmetry breaking and related phenomena.1), 2) The NJL model can be improved by th...
