The effect of error feedback on the accuracy of output task types such as editing task, text reconstruction task, picture cued writing task, and dictogloss task, has not been clearly explored. Following arguments concerning that the combination of both corrective feedback and output makes it difficult to determine whether their effects were in combination or alone, the purpose of the present st...

Abstract The extent to which teachers’ written corrective feedback (WCF) is conducive to ESL learners’ improvement has been discussed since Truscott’s claim in 1996. The mentioned debate continues because there has been lots of contrastive research studies with different results. This paper presents the results of a 2-month study of the effectiveness of WCF to 65 low intermediate Iranian learne...

This paper investigates the event-triggered tracking control of nonstrict-feedback nonlinear system with time-varying disturbances. While fuzzy logic systems (FLSs) approximate unknown dynamics, an compound learning algorithm is originally developed to accurately estimate total uncertainties. By referring adaptive model, laws are derived without provoking problem “algebraic loop,” seeing Remark...

Recently the class of BPA (or context-free) processes has been intensively studied and bisimilarity and regularity appeared to be decidable (see [CHS95, BCS95, BCS96]). We extend these processes with a deadlocking state into BPAδ systems. Bosscher has proved that bisimilarity and regularity remain decidable [Bos97]. We generalise his approach introducing strict and nonstrict version of bisimila...

Extended abstract. Obtaining maximum performance from parallel distributed memory machines with a large number of processors depends on partitioning parallel programs into modules and scheduling these modules for the shortest possible execution time. The scheduling problem is known to be NP-hard [2] and heuristic algorithms have been proposed to obtain optimal and sub optimal solutions [1,3,10,...

China Abstract We consider adaptive compensation for infinite number of actuator failures in the tracking control of uncertain nonlinear systems. We construct an adaptive controller by combining the common Lyapunov function approach and the...
