To explore the effects of formative assessment on student engagement in classroom, 60 upper-intermediate level EFL students, were chosen out of a convenience sample of 120, using the Oxford Placement Test and were randomly assigned to experimental and control groups. After the intervention, the students were asked to complete the Student Course Engagement Questionnaire. Independent sample t-tes...

this research study aimed at investigating whether using peer-provided feedbacks rather than teacher-provided comments would result in any significance difference in iranian english undergraduate students’ ability in writing. in so doing, based on a pretest (an opt & a writing exam), 40 subjects were assigned to two homogeneous groups of equal number the subjects in the control group received m...

This paper contributes a first study into how different human users deliver simultaneous control and feedback signals during human-robot interaction. As part of this work, we formalize and present a general interactive learning framework for online cooperation between humans and reinforcement learning agents. In many humanmachine interaction settings, there is a growing gap between the degrees-...

a fault-tolerant control (ftc) methodology has been presented for nonlinear processes being imposed by control input constraints. the proposed methodology uses a combination of feedback linearization and model predictive control (flmpc) schemes. the resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the design context ...

Abstract This paper deals with the event‐triggered dynamic output feedback control for fuzzy systems against denial‐of‐service (DoS) attacks. The DoS attack behavior is modeled using a binary Markov chain to reflect unreliability of communication channel. To reduce network overhead, novel probabilistic protocol uncertain probabilities introduced. Additionally, potential mismatches between premi...
