TDMA protocols have attracted a lot of attention for underwater acoustic sensor networks (UWSNs), because of the unique characteristics of acoustic signal propagation such as great energy consumption in transmission, long propagation delay 28x48 mirror and long communication range.Previous TDMA protocols all allocated transmission time to nodes bas
Aethina tumida, commonly known as the small hive beetle, poses a threat to honeybee populations, particularly Apis mellifera, across several European regions.Originating in sub-Saharan Africa, there is a risk of the infestation spreading from Calabria, a region in the south of Italy.The essential role played by Apis spp.in pollination biodiversity
We propose a design for a float capable of harvesting wave wac 4011 energy while fully submerged.The proposed design could theoretically operate indefinitely without ever breaching the surface.We developed and validated design guidelines for the proposed float through a combination of tank testing and simulation.These 28x48 mirror design insights c
