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 ...

We propose a secure data aggregation (SDA) framework for mobile sensor networks whose topology changes dynamically with time. The SDA framework (designed to be resilient to both insider and outsider attacks) comprises of a pair-wise key establishment mechanism run along the edges of a data gathering tree and a distributed trust evaluation model that is tightly integrated with the data aggregati...

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...

In this work we present results from using Amazon’s Mechanical Turk (MTurk) to annotate translation lexicons between English and a large set of less commonly used languages. We generate candidate translations for 100 English words in each of 42 foreign languages using Wikipedia and a lexicon induction framework. We evaluate the MTurk annotations by using positive and negative control candidate ...

We present an overview of the second shared task on language identification in codeswitched data. For the shared task, we had code-switched data from two different language pairs: Modern Standard ArabicDialectal Arabic (MSA-DA) and SpanishEnglish (SPA-ENG). We had a total of nine participating teams, with all teams submitting a system for SPA-ENG and four submitting for MSA-DA. Through evaluati...
