Context-awareness is an important topic in the wireless sensor networks research field. Wireless sensor networks comprise wirelessly enabled embedded systems for data acquisition and control for a wide array of applications. This paper introduces a novel embedded systems firmware model based on a layered model with context and cognitive planes. The novel architecture focuses on dynamic adaptabi...

Studies of the dependency between complex, dynamic systems and their human operators often focus on human-computer interactions without considering the emergent properties of human-machine systems in use. As systems become more complex, and typical operating environments more dynamic, the role of the operator has typically changed from providing manual to cognitive control. The nature of the in...

Complex cognition addresses research on (a) high-level cognitive processes – mainly problem solving, reasoning, and decision making – and their interaction with more basic processes such as perception, learning, motivation and emotion and (b) cognitive processes which take place in a complex, typically dynamic, environment. Our focus is on AI systems and cognitive models dealing with complexity...

Cognitive radio is an emerging wireless technology that allows dynamic system reconfiguration, promising dramatic improvements in spectrum utilisation. Unlicensed spectrum sharing is the theme that binds cognitive radio and ultrawideband technologies. This paper presents an assessment of cognitive techniques for ultrawideband systems, highlighting the characteristics of this highly flexible, sp...

With the constant advances in cognitive radio technology, there is a developing need for proper testing facilities. This paper introduces efforts to bring together research and development of cognitive radio, dynamic spectrum access (DSA), and software defined radio systems to enable testing in real-world environments, and to develop applications for these emerging systems. Using licensed test ...

Cognitive Architectures (CAs) are the core of artificial cognitive systems. A CA is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. Over the years a number of distinct CAs have been proposed by different authors and their limitations and potentials were investigated. These CAs are usually classified as symbolic and...

in this paper, a mixed-integer linearized programming (minlp) model is presented to design a group layout (gl) of a cellular manufacturing system (cms) in a dynamic environment with considering production planning (pp) decisions. this model incorporates with an extensive coverage of important manufacturing features used in the design of cmss. there are also some features that make the presented...

A critical factor facilitating the "cognitive revolution" of the early 1960's was the capability of formulating rigorous (computational or mathematical) models of how the inputs and outputs from mental processing systems change over time. The earliest approach was to view the mind as a dynamic cybernetic feedback system (see Miller, Gallanter, & Pribram, 1960). But this was later abandoned in f...
