A new improved CSMA/CA algorithm for wireless sensor networks (WSNs) is proposed in this paper to save energy and prolong the life cycle of WSNs. This algorithm is combined with the artificial neural network and Bayesian algorithm according to the practical applications of the drug control system of the Internet of Things. The algorithm is divided into two(More)
The Precision of PWV inversed using GPS data already achieved 1-2mm, which may be used as an examination on precision of the PWV acquired by other methods. Observes the stand regarding the local area without GPS observing station. The square curve fitting model of water vapor pressure and PWV founded in this article can be used to rapidly gain the PWV by(More)
Cucurbit[7]uril (CB[7]) has received increasing attention because of its unique structure and multiple recognition properties. To improve the sensitivity of surface plasmon resonance (SPR) biosensors, we designed a novel strategy in which caspase-3 serves as the model analyte and CB[7]-modified AuNPs (CB[7]-AuNPs) act as the intermedium. The substrate(More)
