background and aim : )co-op( is a client-centered cognitive-based approach that focuses on individual abilities to achieve his/her functional goals. this approach is based on the assumption that cognition plays an important role in acquisition of functional skills, and is used to gain new skills and improve previous skills. the purpose of this paper is to systematically review studies on co-op ...

The primary objective of cooperation in cognitive radio (CR) networks is to increase the spectrum access efficiency and improve the network performance. However, Byzantine adversaries or unintentional erroneous conduct in cooperation can lead to destructive behavior of CR users that can decrease their own and others’ performances. This work presents a dynamic solution for cooperation reliabilit...

objectives: one of the education ministry’s concerns in high schools is the problem of academic achievement. the researches have mentioned that student’s false attribution and absence of scholastic counseling service are the most important factors affecting student’s low performance and achievements. the main goal of this research was to study the rate of cognitive reconstructive effect on attr...

in this article,we briefly analyse cognitive science and cognitive economics. generally, there are two main theories related to cognitive science and brain performance models. first theory which are inspired by computer and artifical intelligence and second the connectionist models. the connectionist theory is the most prevalent in cognitive science now. hayek and north ,the two nobel laureates...

the present study aims to investigate language learners’ cognitive processes in on-line esp courses. three modes of inquiry are used: think-aloud protocol analysis, screen capture analysis, and correlation analysis. the theoretical foundations for the evaluation of the cognitive aspect of ferdowsi univeristy of mashhad e-learning system are drawn from cognitive load theory, cognitive apprentice...

objectives: the role of cognitive process for postural control was shown in dual task studies. however, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. this study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...

This paper proposes a resource intensive traffic-aware scheme, incorporated into an energy-efficient routing protocol that enables energy conservation and efficient data flow coordination, among secondary communicating nodes with heterogeneous spectrum availability in distributed cognitive radio networks. The proposed scheme associates the backward difference traffic moments with the sleep-time...

The ability to model independent decision makers whose actions potentially affect all other decision makers makes game theory attractive to analyze the performances of wireless communication systems. Recently, there has been growing interest in adopting game theoretic methods to cognitive radio networks for power control, rate adaptation and channel access schemes. This work presents several re...
