In this article, we study an adaptive finite-time event-triggered command filtered control problem based on output feedback for a class of nonstrict-feedback nonlinear systems with unknown directions. Firstly, the continuous functions in are approached by fuzzy logic systems, and coordinate transformations Nussbaum function technique introduced to settle caused directions systems. Then, order r...

In this paper, we use formal specification techniques to provide precompiled and provably correct domain-specific knowledge to autonomous agents. This allows for verifying agent interactions in the environment. In particular, we show that negotiating agents can resolve mutually incompatible local preferences and settle for an acceptable compromise by reasoning with formally specified default an...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...

group dynamic assessment (g-da) grounded in vygotsky’s socio-cultural theory (sct) is believed to have the potential to provide a context for capturing a group of learners’ zone of proximal development (zpd) (poehner & lantolf, 2010; shabani, 2010). the present study aims at testing the applicability of g-da in identifying the mediational strategies offered by a mediator during his g-da int...

judgement about friedrich nietzsche as a criticizer of modern culture and a new establisher in culture and thought of the new world, is a very difficult task. but criticizing of morality, philosophy and culture during the last ages is an effort that nietzsche has done it and in this way he notified the effects of corruption on human will and life. nietzsche in his new establishing in reaction t...
