A new language generating mechanism is defined. It is derived from a generalization of the two-level substitution mechanism and involves several (incomplete) grammars which communicate with each other by introducing variables for which they have no productions themselves. When the grammars are context-free, this yields an alternative definition for the

Metrics for Cooperative Systems
Proceedings of the 18th International Conference on Supporting Group Work, 2014This paper proposes performance indicators and metrics for the analysis of shared workspaces. We investigate user activity in various electronic workspaces of a shared workspace system and compare these on the basis of the proposed metrics: activity, productivity and cooperativity.

Cooperative Systems Modeling, Example of a Cooperative e-maintenance System
2005 International Symposium on Computational Intelligence in Robotics and Automation, 2005Cooperation is an efficiency factor in many activities like design, medicine or maintenance. Several researches try to optimize cooperation activity by using tools or algorithms designed to enhance human interaction. Few researches are made on conceptual cooperation modeling.

Cooperating scheduling systems
International Journal of Manufacturing Technology and Management, 2001An architecture and a procedure for communicating scheduling expert systems based on fuzzy set theory is proposed. Fuzzy sets are used to express and to exchange constraints and their potential relaxation with the cooperating scheduling system that can interpret these constraints.

Cooperative regions for coded cooperative systems [mobile radio systems]
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005Cooperation of mobiles provides signal diversity in wireless networks. We consider a coded cooperative system under Rayleigh fading and path loss. For an arbitrary signal to noise ratio, we find conditions on the user geometry for two-user cooperation to be beneficial.

To Cooperate or Not to Cooperate: System Throughput and Fairness Perspective
IEEE Journal on Selected Areas in Communications, 2012The cooperative transmission, in which some nodes help the transmission of other nodes, has been actively studied to overcome the channel fading effects that deteriorate the communication quality. Thus far, most researches on the cooperative transmission have been studied from the reliability point of view focusing on a single transmission and showing ...

Cooperating Distributed Splicing Systems
J. Autom. Lang. Comb., 1999We introduce a new class of cooperating distributed H systems which consist of a given set of splicing systems (sets of splicing rules plus sets of axioms), similar in form to the cooperating distributed grammar systems. By applying iteratively the components of such a system (starting from a given initial string), in a sequence which runs ...

A cooperative system for metaheuristic algorithms
Expert Systems with Applications, 2021Abstract Optimization problems are defined as the functions whereby the target is to find the optimum state depending on the parameters that have certain limitations. In the field of optimization, the aim is to find from among multiple alternative solutions the optimal solution or approximate solution that provides all the restrictions. Metaheuristic
