The formation of copper nanoparticles (Cu-NPs) in irradiated aqueous solutions of star-shaped poly(acrylic acid) (PAA) were studied at two pH values. Transmission electron microscopy (TEM) demonstrates that the star-shaped macromolecules loaded with Cu(2+) ions can act as individual nanosized containers providing a perfect control over the size and size(More)
Mobile wireless sensor networks have recently attracted considerable attention. In particular, there is a significant interest in applying mobile sensor networks to wildlife and environmental monitoring, medical, and human-centric applications. Energy is a critical factor for most real deployments of sensor networks: many mobile applications, such as(More)
In this study, the authors develop and present a comprehensive analysis of two opportunistic cooperative relaying schemes for long term evolution (LTE)-advanced networks operating over generalised-K and Nakagami-m fading channels. They present and compare the performance of opportunistic relaying (OR) and opportunistic hybrid automatic repeat request(More)
