The parameter identifiability problem for dynamic system ODE models has been extensively studied. Nevertheless, except for linear ODE models, the question of establishing identifiable combinations of parameters when the model is unidentifiable has not received as much attention and the problem is not fully resolved for nonlinear ODEs. Identifiable combinations are useful, for example, for the r...

It is widely acknowledged that teachers' work has both practical and theoretical dimensions, praxis logos, teacher education should address dimensions. However, as argued in this article, existing discourses for describing the mathematical knowledge of teachers what it takes to become competent are not always clear extent these about practices mathematics teaching or theories provide arguments ...

The present quasi-experimental study mainly investigates the role of literature as input for reading comprehension in Iranian EFL classrooms. To be more exact, it investigates the effects of authentic and simplified literary texts on the reading comprehension of Iranian advanced EFL learners. The participants were 35 male and female Iranian EFL learners who were at advanced level, studying in a...

Web Services are interfaces to a collection of operations that are network-accessible through standardized XML messaging, and whose features are described using standard XML-based languages. Semantic Web Services (SWS) describe semantically the internal structure and the functional/nonfunctional capabilities of the services, facilitating the design and evaluation of SWSs based on that semantic ...

This work investigates the performance of Differential Evolution (DE) and its opposition-based version (ODE) on large scale optimization problems. Opposition-based differential evolution (ODE) has been proposed based on DE; it employs opposition-based population initialization and generation jumping to accelerate convergence speed. ODE shows promising results in terms of convergence rate, robus...

Hideo Kojima's Metal Gear Solid, (MGS) is widely recognized by both gamers and industry professionals as one of the most influential games of all time. In this paper we contend that one of the ways in which the literary merit of a game can be explained is through the use of close critical literary readings of the game text together with a discussion of how the yielded interpretations work colle...
