Security is a critical issue for sensor networks used in hostile environments.When wireless sensor nodes in a wireless sensor network are distributed Animals in an insecure hostile environment, the sensor nodes must be protected: a secret key must be used to protect the nodes transmitting messages.If the nodes are not protected and become compromis
Forecasting the biomass-based energy potential using artificial intelligence and geographic information systems: A case study
To meet the energy demand in a sustainable way, fossil fuels must be substituted with alternative resources and technologies.This transformation is encouraged to reduce greenhouse gases using environmental-friendly practices.Although our country is rich in biomass resources due to climate, land conditions, agriculture and animal husbandry activitie
Arctic fishes reveal patterns in radiocarbon age across habitats and with recent climate change
Abstract Climate change alters the sources and age of carbon in Arctic food webs by fostering the release of older carbon from degrading permafrost.Radiocarbon (14C) traces carbon sources and age, but data before rapid warming are rare and limit assessments over time.We capitalized on 14C data collected ~?40?years ago that used fish as natural samp
