Communication systems reliably self-organize in populations of interacting agents under certain conditions. The various fields which model this – game theory, cognitive science and evolutionary linguistics – make different assumptions about the learning and behavioral processes which are responsible. We created an exemplar-based framework to directly compare these approaches by reproducing prev...

Information literacy embraces the ability to access useful information, to have the awareness organizing knowledge and information requiring different methods of search and most effective diagnostic information for problem solving and decision-making. Those who lack these abilities are continuously confused in the vast ocean of information. This study investigated designing model of educators’ ...

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

the aim of this work is to use self organizing map (som) for clustering of locomotion kinetic characteristics in normal and parkinson’s disease. the classification and analysis of the kinematic characteristics of human locomotion has been greatly increased by the use of artificial neural networks in recent years. the proposed methodology aims at overcoming the constraints of traditional analysi...

The author reports on a universal searchable index of Web resources for design engineering. The project is part of the Web site for the Canadian Design Engineering Network (CDEN), a recently funded national initiative to provide a mechanism for design engineering practitioners, educators, and others to access recent information on the field, to collaborate, and to help student learn design engi...

This study examines the process of strategic decision making within organizations by analyzing four commonly used information aggregation structures: individual decision making, delegation to experts, voting, and averaging of opinions. Using a formal mathematical model, we investigate how the performance of each of these structures is contingent upon the breadth of knowledge within the firm and...
