In this study, a novel collaborative method is developed to optimize hybrid sensor networks (HSN) for environmental monitoring and anomaly search tasks.A weighted Gaussian coverage method hs been designed for static sensor allocation, and the Active Monitoring and Anomaly Search System method is adapted to mobile sensor path planning.To validate th
Blind Synchronization in Asynchronous UWB Networks Based on the Transmit-Reference Scheme
Ultra-wideband (UWB) wireless communication systems are based on the transmission of extremely narrow pulses, with a duration inferior to a nanosecond.The application of transmit reference (TR) to UWB systems allows to side-step channel estimation at the receiver, with a tradeoff Plastic Pipes of the effective transmission bandwidth, which is reduc
Study on the penetration protection of a fiber-reinforced composite structure with CNTs/GFP clip STF/3DKevlar
A fiber-reinforced composite structure with carbon nanotubes-reinforced glass fiber panel (CNTs/GFP) clip and Statues three-dimensional Kevlar fabric impregnated with shear thickening fluid (STF/3DKevlar) is proposed (CNTs/GFP-STF/3DKevlar).On this basis, the preparation, mechanical properties, and energy dissipation characteristics of CNTs/GFP, ST
The impact of loneliness on physical and mental health among older adults in the era of coronavirus disease 2019 pandemic
Coronavirus disease 2019 (COVID-19) pandemic has a significant negative impact on emotions and feelings of loneliness in terms of lack of companionship, social isolation, and connections in older adults.Compulsive loneliness can negatively alter cognition, mental, and physical health and lifespan in the elderly.Isolation and restricted social inter
