Environmental concerns about using fossil fuels, and their resource constraints along with energy security concerns, have spurred great interest in generating electrical energy from renewable sources. The variable and stochastic nature of renewable sources, however, makes solar and wind power diffi cult to manage, especially at high levels of penetration. Electrical energy storage (EES) is nece...

The cellular electrophysiologic effects of myocardial ablation performed in vitro with argon laser energy were compared with those of high-energy electrical shocks. A border zone of injured but nonnecrotic tissue surrounding the site of energy delivery was present after tissue ablation by both energy modalities. A decrease in resting membrane potential, action potential amplitude, and maximum r...

High-tension (HT) consumers have to pay a maximum demand charge in addition to the usual charge for the number of units consumed. This charge is usually based on the highest amount of power used during some period (say 30 minutes) during the metering month. The maximum demand charge often represents a large proportion of the total bill and may be based on only one isolated 30 minute episode of ...

The paper recalls some fundamental notions, developed by Otto Meyerhof, which were used in the analysis of the transduction of chemical into mechanical energy during muscular contraction. These notions formed the basis of the approach to the analysis of the transduction of chemical into electrical energy, i.e., the very principle underlying nerve and muscle excitability and bioelectricity. Inst...

In this paper, the functions that can be automated in distribution systems can be classified into two categories, namely, monitoring functions and control functions. Monitoring functions are those needed to record meter readings at different locations in the system, the system status at different locations and events of abnormal conditions. The data monitored at the system level are not only us...

Piezoelectric Energy Harvesting Systems play a vital role in energizing microelectronic devices with the low-frequency operation. Here, novel piezoelectric energy harvesting device has been developed for low power electronic devices. The consists of cantilever poles projecting outwards and cantilevers one end is connected to wind-catcher, another torsional spring. signifies its application plac...

IEEE Press has published “Electrical Safety Engineering of Renewable Energy Systems,” by Rodolfo Araneo and Massimo Mitolo. This 288-page book provides a study safety issues with renewable energy, covering systems including photovoltaics (PVs) wind turbines guiding the reader safety-by-design methodology. DC system concerns, grounding bonding, lightning protection are thoroughly d...
