Intelligence is a very important characteristic for cognitive radios networks. Design of cognitive engine and application of artificial intelligence techniques are key to the implementation of this characteristic. In this paper, we have proposed a system model of cognitive network which is based on the concept of multiple cognitive terminals sharing the same set of channels. The effect of numbe...

We consider the use of cognitive models as both models of human cognitive function and human-compatible decision aids. The domain of application is prediction based on partial information in the context of emergency events where the availability and timeliness of information is limited. The cognitive model is based on the memory retrieval processes of the ACT-R cognitive architecture, most spec...

This paper describes the application of cognitive mapping techniques, for eliciting and representing cognitive structure, to the problem of user requirement capture for the design of an electronic database. The research is based upon the assumption that organising information so as to be compatible with the structure of users' knowledge will enhance information retrieval by supporting more effe...

Aiming to ensure safety of operation to application providers and improve the usability of human computer interactions during authentication, this paper proposes a two-step personalization approach of user authentication tasks based on individual differences in cognitive processing as follows: i) recommend a textual or graphical user authentication mechanism based on the users’ cognitive styles...

The present paper deals with the application of a cognitive-behavioral protocol targeting intolerance of uncertainty (CBT-IU) to a hypothetical clinical case of GAD.
