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 ...

Strangeness in Ultrarelativistic Nuclear Collisions

Production of strangeness was among the first observables studied in ultrarelativistic nuclear collisions in the search for quark-gluon plasma (QGP). The transition into plasma phase was expected to facilitate strangeness production and lead to its enhanced abundance [1]. It is namely rather costly to produce strangeness in a hadronic system; the lowest threshold which is about 530 MeV above th...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

JÕc suppression in ultrarelativistic nuclear collisions

Using a multiphase transport model, we study the relative importance of J/c suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion Collider. We find that for collisions between heavy nuclei such as Au1Au, both plasma screening and gluon scattering are important. As a result, the effect due to absorption by ha...
