Current WWW technology is becoming the de-facto standard platform for groupware applications, yet it provides virtually no effective coordination capabilities. New applications, instead, demand higher-level middleware services, with intelligent behaviours, deductive capabilities, and effective coordination. In this work we discuss a possible extension to the current Web-based architectures whos...

Acomparative investigation of the coordination behaviour of a 19-memberedNO2S2-macrocycle (L ) and a 20-membered NO2S3-macrocycle (L ) is reported. On silver(I) complexation, L yields a discrete endocyclic mononuclear complex, whereasL affords a one-dimensional coordination polymer inwhich the endo-coordinatedmacrocyclic complex units are linked by silver(I) ions outside the cavity via endo–exo...

Opacity is a confidentiality property that characterizes the non-disclosure of specified secret information of a system to an outside observer. In this paper, we consider the enforcement of opacity within the discrete-event system formalism in the presence of multiple intruders. We study two cases, one without coordination among the intruders and the other with coordination. We propose appropri...

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...

There is little or no guidance to systematically design a selforganising emergent solution that achieves the desired macroscopic behaviour. This paper describes decentralised coordination mechanisms such as digital pheromones as design patterns, similar to patterns used in mainstream software engineering. As a consequence, a structured consolidation of best practice in using each coordination m...

It has been suggested that interjoint coordination may serve to reduce joint stress and muscular demand and to maintain balance during dynamic lifting tasks, thus having implications for safe lifting practices. Before recommending the use of an on-body ergonomic aid, the Personal Lift-Assist Device (PLAD), it is important to determine any effects this device may have on interjoint coordination....

In STOC’16, Fraigniaud et al. consider the problem of finding a treasure hidden in one of many boxes that are ordered by importance. That is, if a treasure is in a more important box, then one would like to find it faster. Assuming there are many searchers, the authors suggest that using an algorithm that requires no coordination between searchers can be highly beneficial. Indeed, besides savin...
