this paper examines the theoretical rationales and practical aspects of task-based language teaching (tblt) with particular reference to research findings in efl/esl contexts. the definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  moreover, fact...

In the present paper, a new 2-D Van der Polstructural oscillator model is introduced for the vortex induced vibrations of circular cylinders.The main purpose of this task is to control the recently introduced model by means of modern control definitions in state space. In order to control the system, the whole model is linearized about its equilibrium point by deriving state-space matrices. The...

The GFLOPS project's aim is to develop a parallel architecture as well as its software environment to implement scientific applications efficiently. This goal can be achieved only with a real collaboration among the architecture, the compiler and the programming language. This paper investigates the C// Parallel language and the underlying programming model on a global address space architectur...

A credible theory of intelligence must provide a satisfactory account of the wide spectrum of learning abilities displayed by humans and some other animals. One of the most impressive of these is skill acquisition—the ability to create new skills, refine them through practice, and apply them in new task contexts. This ability to retain and refine solutions to important subproblems and then empl...

The simultaneous consideration of various notions (practice, procedure, prescribed task, effective task, task space, task search, task, method, activity) shows that the task accomplishment cannot be discussed at a general level, as classical approaches do. Rather, this paper points out the importance to distinguish the task definition and the task realization because the former is mainly static...
