It is well known that the successful operation of cognitive radio (CR) between CR transmitter and CR receiver (CR link) relies on reliable spectrum sensing. To network CRs requires more information from spectrum sensing beyond traditional techniques, executing at CR transmitter and further information regarding the spectrum availability at CR receiver. Redefining the spectrum sensing along with...

Introduction The authors were all involved in the 'seminal' Utopia project, 1981-85, where Cooperative Design methodology, involving users very early in the design process, had an early development and application in the use of computers. One strong goal was to 'give the end users a voice' in design and development of computer support in work places, thus enhancing the quality of the resulting ...

COOPERATIVELY CONTROLLED OBJECTS IN SUPPORT OF COLLABORATION by Lauren J. Bricker Chairperson of the Supervisory Committee: Professor Steven L. Tanimoto Department of Computer Science and Engineering Developing applications to support collaboration by two or more users involves special challenges. An application designer should anticipate the interaction between the user and the computer, as we...

Cooperative advertising is a cost-sharing mechanism in which a part of retailers' advertising investments are financed by the manufacturers. In recent years, investment among advertising options has become a difficult marketing issue. In this paper, the cooperative advertising problem with advertising options is investigated in a two-period horizon in which the market share in the second period...

This paper develops a methodology for decision-making in organizationally distributed systems where decision authorities and information are dispersed in multiple organizations. Global performance is achieved through cooperative interaction and partial information sharing among organizations. The information shared among organizations is contrived using modified Lagrangian relaxation techniques...

In this article we proposed an improved SIFT-based object recognition methodology for robot applications. This methodology is employed for implementing a robot-head detection system, which is the main component of a robot gaze direction determination system. Gaze direction determination of robots is an important ability to be developed. It can be used for enhancing cooperative and competitive s...

Most of emotional speech databases are recorded by actors and some of spontaneous databases are not free of charge. To progress in emotional recognition, it is necessary to carry out a big data acquisition task. The current work gives a methodology to capture spontaneous emotions through a cooperative video game. Our methodology is based on three new concepts: novelty, reproducibility and ubiqu...

Due to the increasing amount of collaborative work in engineering, it is now necessary to create environments that foster the coordination and cooperation among engineering groups. The aim of this paper is to present a methodology to design and integrate ‘Collaborative Engineering Environments’ supported by tools that enable cooperative work and intellectual capital sharing. The resulting metho...

This paper proposes a new effective behaviour-based reactive navigation methodology for autonomous mobile robot. Its main contribution is based on newly proposed egocentric 'homeostatic ' approach by which behaviours are coordinated while taking advantages of both competitive and cooperative method. In order to accomplish autonomous navigation, direction and velocity are modulated automatically...
