The coordination sequence sΛ(k) of a graph Λ counts the number of its vertices which have distance k from a given vertex, where the distance between two vertices is defined as the minimal number of bonds in any path connecting them. For a large class of graphs, including in particular the classical root lattices, we present the coordination sequences and their generating functions, summarizing ...

A number of existing Distributed Processing Environments (DPEs) are eligible to serve as a coordination architecture. In order to ease the construction of distributed applications while exploiting existing DPEs, the developer should be provided with notations that allow him to characterize the coordination architecture that is the best suited to his application. Existing DPEs can be distinguish...

Does social network structure influence coordination? We examine a coordination game in which each player engages with an exogenously connected “local” subset of the player population, the pattern of links defining a social network. Players know the number of local links they possess but otherwise have incomplete information about the global network structure. All networks in our experiment hav...

Global games and Poisson games have been proposed to address equilibrium indeterminacy in Common Knowledge Coordination games, where fundamentals are commonly known by all players. Global games assume that agents face idiosyncratic uncertainty about economic fundamentals, whereas Poisson games model the number of actual players as a Poisson random variable to capture population uncertainty in l...

Coordination models and languages represent a new approach to design and development of concurrent systems. The interest in coordination has intensified in the last few years, as evidenced by the increasing number of conferences, tracks, and papers devoted to this topic, and by the recent upsurge of research activity in the theoretical computer science community in this field. The field is rela...

objectives: the aim of this research is to compare cognitive flexibility and adjustment between two groups of students with developmental coordination disorder (dcd) and typically developing students. methods: for this purpose, 50 students with dcd and 50 typically developing students were chosen among 12 primary schools. the developmental coordination disorder questionnaire (dcd-q), adjustment...

one effective method for improving the performance of supply chain is making coordination among members of supply chain. this paper studies the subject of coordination of supply chain by using an insurance contract. the supply chain consists of one-manufacturer and one-retailer that the retailer is faced with potential demand and returning of goods from customer. acceptance of goods returned is...
