Energy harvesting wireless sensor network (EH-WSN) is considered to be one of the key enabling technologies for the internet of things (IoT) construction.Although the introduced EH technology can alleviate the energy limitation problem that occurs in the traditional wireless sensor network (WSN), most of the current studies on EH-WSN fail to adequa
The Stirling engine is one of the most promising devices for the recovery of waste heat.Its power output can be optimized by several means, in particular by an optimized piston motion.Here, we investigate its potential performance improvements in the presence of dissipative processes.In order to ensure the possibility of a technical implementation
Introduction As old-age pensions continue to expand Helicopter Kit around the world in response to population ageing, policymakers increasingly wish to understand their impact on healthcare demand.In this paper, we examine the effects of supplemental income to older adults on healthcare use patterns, expenditures and insurance uptake in Yucatan, Me
