Rheological models for polymer solutions and melts based on the finitely extensible non-linear elastic (FENE) dumbbell theory are reviewed in this study. The FENE-P model that is a well-known Peterlin approximation of the FENE model, indicates noticeable deviation from original FENE predictions and also experimental results, especially in the transient flow. In addition, both FENE and FENE-P mo...

A new phenomenological cluster-hadronization model is presented. Its specific features are the incorporation of soft colour reconnection, a more general treatment of diquarks including their spin and giving rise to clusters with baryonic quantum numbers, and a dynamic separation of the regimes of clusters and hadrons according to their masses and flavours. The distinction between the two region...

Higher Education Institutions are required to invent means and tools to meet the increasing demand of students’ enrolment. ELearning is one of these potential means which indicates that the issue of the quality of eLearning models is essential. A developed two-stage, Multi-Input-Single-Output SCeQLM a eLearning quality model has been reviewed. SCeLQM is based on ten Critical Success Factors, CS...

Variations on the notions of Reedy model structures and projective model structures on categories of diagrams in a model category are introduced. These allow one to choose only a subset of the entries when defining weak equivalences, or to use different model categories at different entries of the diagrams. As a result, a bisimplicial model category that can be used to recover the algebraic K-t...

this paper describes a modified structural dynamics model for aeroelastic analysis of high-aspect-ratio wings undergoing large deformation behavior. to gain this aim, a moderate deflection beam model is modified with some important large deflection terms and then coupled with a state space unsteady aerodynamics model. finite element method is used to discretize the equations of motion. a dynami...

this paper analyzes the relationship between capital structure and earning management. for analysing we used 119 non-financial companies that listed in tehran stock exchange from 2000 to 2008. the researchers will focus on comparing the jones model and the modified jones model, which are the two most frequently used model in empirical analysis nowadays. earnings management is a kind of manageme...
