Abstract The purpose of this work is to design an energy scavenging system. system scavenges ambient from indoor Wi-Fi routers. It makes use low cost, environment-friendly and widely available corrugated cardboard substrate. circuit realized on metallic layers made low-cost copper tape. A Villard rectifier used convert the RF into dc. measured scavenged power at density 10 μ W cm −2 −15.76 dBm ...

There are many knowledge-based data mining frameworks and it is common to think that new ones can not come up with anything new. This article refutes such claims. We propose a sophisticated unification mechanism and two-tier machine cache system aimed at saving time and memory. No machine is run twice. Instead, machines are reused wherever they are repeatedly requested (regardless of request co...
