The reduction in energy demand by portable electronics has rekindled interest the use of renewable sources built environment. This technological study focuses on a sophisticated piezoelectric material harvesting method. Piezoelectric materials can be used to convert mechanical energy, such as environmental vibrations, into electrical which then stored and power other devices. When stress is app...

Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...
