We consider a swarm of mobile robots evolving in bidimensional Euclidean space. study the stronger variant crash-tolerant gathering: if no robot crashes, have to meet at same arbitrary location, not known beforehand, finite time; one or several crash remaining correct gather location rescue them. Motivated by impossibility results semi-synchronous setting, we present first solution problem for ...

Abstract This study aimed to adapt the Children’s Natural Environment Signaling Scale Brazilian context, gathering evidence of validity and precision. Specifically, it sought verify presence violent behavior in adolescents’ family environment identify victims this type violence. A total 249 adolescents, between 13 19 years old, participated study. The results pointed existence few situations in...

Social network game (SNG) is attracting more and more players and becoming a promising market for game providers. Competing game providers are also constantly providing substitutes to attract SNG players to switch among SNGs. In prior IS literature few studies have tried to investigate the switching behaviour. In order to explore IS user’s switching behaviour in SNGs, we examine the determinant...

This paper addresses a methodology for the optimal conceptual design of thermochemical fuel production processes from biomass. A decomposed modelling approach with separate energy-flow, energy-integration and economic models are coupled with a multi-objective optimisation strategy. It is applied to the design of a process that produces synthetic natural gas (SNG) from lignocellulosic materials....

It’s common to accompany the rollout of a new biomedical journal with an explanation for its coming into being, usually by suggesting there’s an unmet need, despite the panoply of existing journals. I’m not going to do that, at least not exactly. The biomedical literature is almost unimaginably vast already, much more than even the most diligent speed-reading scholar-who-listens-to-science-blog...
