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 ...

BACKGROUND Clostridium difficile infection (CDI) is a common and potentially fatal healthcare-associated infection. Improving diagnostic tests and infection control measures may prevent transmission. We aimed to determine, in resource-limited settings, whether it is more effective and cost-effective to allocate resources to isolation or to diagnostics. METHODS We constructed a mathematical mo...

The objective of this research is to develop a turbine blade investment casting cost advisor model to assist a blade designer in decision-making in a concurrent engineering environment. It is a microcomputer based cost estimating system that employs a manufacturing knowledge base. The concept of the manufacturing process for blade production by the investment casting method is used to develop t...
