This review paper discusses the Reo coordination language in the wider context of its research area. It explains the concept of coordination and argues its significance. Those concepts, models and languages that were of considerable importance in the preliminary research that lead up to the development of Reo, are explained, discussed and evaluated. In particular Linda, Manifold, and Reo itself...

nanoparticles of coordination polymer [co2(pydc)2(h2o)6]n.2n h2o [h2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder x-ray diffraction, scanning electron microscopy, dls particle size analysis and tga/dta. the structure of single crystalline coordination polymer developed from nanosized coo...

Coordination structures of the Co(+)(NH(3))(n) and Ni(+)(NH(3))(n) ions are probed by infrared (IR) photodissociation spectroscopy with the aid of density functional theory (DFT) calculations. The IR spectra of N(2)-tagged Co(+)(NH(3))(n) (n = 1-4) exhibit two distinct bands assignable to the symmetric and antisymmetric NH stretches of the NH(3) molecules binding directly to Co(+). Size-depende...

The locations of critical points of lattice models (such as Ising models, percolation problems or self-avoiding walks) depend on the topological structure of the underlying graph, in particular on the dimension and on the (mean) coordination number. However, this can only be a first approximation, and more detailed information on the graph is required for a better understanding of the precise l...

We investigated the structure of SiO2 glass up to 172 GPa using high-energy X-ray diffraction. The combination of a multichannel collimator with diamond anvil cells enabled the measurement of structural changes in silica glass with total X-ray diffraction to previously unachievable pressures. We show that SiO2 first undergoes a change in Si-O coordination number from fourfold to sixfold between...

Elections represent a coordination problem for voters and candidates for office. Electoral coordination is also the causal mechanism behind any explanation of the relationship between electoral systems and the number of parties. I present a dynamic model of electoral coordination with candidate exit. The model extends two important results from the literature to a dynamic setting. The extension...

A rather recent approach in programming parallel and distributed systems is that of coordination models and languages. Coordination programming enjoys a number of advantages such as the ability to express different software architectures and abstract interaction protocols, supporting multilinguality, reusability and programming-in-the-large, etc. In this paper we show the potential of controlor...
