The Simple Temporal Problem (STP) is a popular representation for solving centralized scheduling and planning problems. When scheduling agents are associated with different users who need to coordinate some of their activities, however, considerations such as privacy and scalability suggest solving the joint STP in a more distributed manner. Building on recent advances in STP algorithms that ex...

this paper studies the problem of synchronizing a moving agent network by decentralized adaptive control strategy. And, each agent node is assigned nonlinear connections with those of neighboring agents. The moving agent network model exhibits a time-varying topological structure in two dimensional spaces. Base on the Lyapunov stability theory, some criteria for the synchronization are achieved...

This paper presents one target of the Evo-business project (2003-2005, conducted at University of Luxembourg) which aims at applying evolutionary algorithms (and more precisely loosely coupled genetic algorithms) to the distributed optimization of functions representing corporate goals within Virtual Organizations. The distribution of the algorithm will be achieved using a standard multi-agent ...

This paper studies the leaderless consensus of stochastic multi-agent systems based on partial differential equations–ordinary equations (PDE-ODEs). Compared with traditional state coupling, most significant difference between this is that space coupling designed. Two boundary couplings are investigated in article, respectively, collocated measurement and distributed measurement. Using Lyapunov...

In this study, solvent extraction method has been utilized for separation of molybdenum and vanadium from nitrate solution by utilizing coupling of acid and solvating extractants (D2EHPA and TBP extractants). The outcomes demonstrated that synergistic solvent extraction improves stability of formatted complexes for transfer to the organic phase. The main parameters such as pH value, concentrati...

Intelligent agent technology has evolved rapidly over the past few years along with the growing number of agent applications in various domains. However, very little work has been dedicated to define quality metrics for the design of an agent-based system. Previous efforts mostly focus on adopting classical metrics such as coupling and cohesion to measure quality of an agent design. We argue th...

Background The silicon tetrahydride or silanes is an inorganic colourless gas with spontaneous combustion in air at room temperature [1–3]. Silane or functionalized silanes has widely industrial and medical applications, and works as coupling and impermeabilizing agent. Silane coupling agents have also been applied to bond glass and carbon fibers to polymer matrices, creating a strong adhesion ...

In this paper we present a method for finding general dependencies between individual agents in a multi-agent system. We use mutual information as the general measure for dependence and demonstrate how it can be used to estimate pair-wise coupling in a 2 dimensional swarm. We then show that our technique of measuring local coupling can find phase transitions in the global behaviour of the system.

A direct β-coupling of cyclic ketones with imines has been accomplished via the synergistic combination of photoredox catalysis and organocatalysis. Transient β-enaminyl radicals derived from ketones via enamine and oxidative photoredox catalysis readily combine with persistent α-amino radicals in a highly selective hetero radical-radical coupling. This novel pathway to γ-aminoketones is predic...
