  This paper proposes a new structure for digital address decoders based on flip-flops with application in wake-up signal generators of wireless networks nodes. Such nodes equipped with this device can be utilized in Internet of Things applications where the nodes are dependent on environment energy harvesting to survive for a long time. Different parts in these wireless nodes should have an e...

The conceptual framework of the “Smart Grid” naturally takes the viewpoint of the grid, then works down into the details of its individual components. This is good and necessary, but there is an alternative approach that can complement and strengthen the “macrogrid” — to start from (very) small “nanogrids”. Nanogrids can be interconnected and aggregated into microgrids, and ultimately, through ...
