We address the challenge of link estimation and routing over highly dynamic links, thats is, bursty links that rapidly shift between reliable and unreliable periods of transmissions. Based on significant empirical evidence of over 100,000 transmissions over each link in 802.15.4 and 802.11 testbeds, we propose two metrics, expected future transmissions (EFT) and MAC3, for runtime estimation of ...

Coral communities in the Persian/Arabian Gulf (PAG) withstand unusually high salinity levels and regular summer temperature maxima of up to ∼35 °C that kill conspecifics elsewhere. Due to the recent formation of the PAG and its subsequent shift to a hot climate, these corals have had only <6,000 y to adapt to these extreme conditions and can therefore inform on how coral reefs may respond to gl...

In the so-called hard or pure sciences , for example, replication studies are common, and play an integral role in the process of testing and demonstrating the generalizability of crucial fi ndings.

occasionally, explaining certain lingual phenomena can be very difficult and complex. for example, one may ask why there are certain types of words or combination of words or why a language contains grammatical, conjugation and syntax structure. all these questions are connected to a long term process of the growth and development of language. everybody uses words without thinking, or rather a ...

While there has been substantial work on referential communication tasks in psycholinguistics, computational and formal modelling (Dale and Reiter (1995), Krahmer and Van Deemter (2012), Frank and Goodman (2012) inter alia), the element we discuss here is incremental processing. Motivated by work in incremental generation of referring expressions (Guhe, 2007; Fernández, 2013) and incremental re...
