Harvesting is proposed to convert mechanical to eleclterical energy based on reverse electrowetting [1] . This energy generates through a novel microfluidic phenomenon. Reverse electrowetting is a process by which liquid motion is converted into electrical energy. It can generate a power up to 103Wm−2‚ by this technology. Reverse electrowetting (REWOD) concept At first‚ The principle of electrowetting is defined in here. The shape of a liquid droplet on a solid layer is characterized by the contact

A New Method for Placement of DG Units in Distribution Networks H.Hedayati‚ S.A.Nabaviniaki‚ Senior Member‚ IEEE‚ and A.Akbarimajd Abstract-- In this paper a new method for placement of DG (distributed generation) units in distribution networks has been presented. This method is based on two factors: analysis of power flow continuation and determination of the most sensitive voltage buses to collapse voltage. This method has been executed on a typical 34-Bus test system. Efficiency of proposed

In order to understand sparking and its potential causes‚ it helps to realize that behind the electrical outlet are wires ready to deliver electricity to your appliance. When you plug in an appliance the electricity makes contact with the plug of the appliance‚ creating a spark. You may not see it very often‚ although the contact is always

The Not So Perfect Human Many technological advances have come in recent years. One of which is the scientific research of genetic engineering. They have found ways to fix genetic mutations‚ cure diseases‚ and even just improve a child’s athletic or intellectual ability. Genetic Scientists are trying to genetically engineer children in the womb‚ but genetic engineering is an inferior practice because of the safety‚ financial‚ and ethical issues. First‚ as our society gets closer and closer to genetic

EARTHQUAKE ENGINEERING IN AUSTRALIA BEFORE MECKERING AND AFTER NEWCASTLE by Charles Bubb BE‚ DIC (Eng. Seis.)‚ FIEAust‚ CPEng SUMMARY Earthquake Engineering in Australia‚ as elsewhere‚ has been formulated in the aftermath of damaging earthquakes. The first Australian Code AS2121-1979 was written and published after the 1968 Meckering WA earthquake. The second AS1170.4 1993 was published after the 1989 Newcastle NSW earthquake. Good quality Building Codes are a necessary basis for sound earthquake
