with regard to the importance of scientific decision-making in power plants prioritization to produce electrical energy (power) from renewable energies (purified), in this paper, research with specialists opinions with respond to questionnaires provided upon three efficient operational criterion in position of three presented power plant in country which used wind, solar water energies for prod...

Bluetooth technology is a low power wireless communication intended to replace the cables connecting many different devices. The low cost Bluetooth technology is open standard technology for implementing short range wireless communication. In this paper two android devices are connected through Bluetooth technology, which controls the electrical devices (Fan, Light) by Voice recognition. The de...

This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call ‘‘ionic cable’’, uses ions to transmit signals, and is built entirely with soft, elastic materials—elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stre...

Twenty new cells have been purchased, in conformity to recent action of the State Board, as an addition to the storage battery plant of this department. The cells have a capacity of forty ampere-hours. T h e r e are now available for direct current work, voltages of 40, 72, n o and 500 volts respectively. This will largely increase the range of experimental work which can be done by electrical ...

The fragility of buried electrical cables is often neglected in earthquakes but significant damage to cables was observed during the 2010–2011 Canterbury earthquake sequence in New Zealand. This study estimates Poisson repair rates, similar to those in existence for pipelines, using damage data retrieved from part of the electric power distribution network in the city of Christchurch. The funct...

Large technical systems serving the everyday needs of people, such as water supply systems, power grids or communication networks, are rich in accumulated metals. Over time, parts of these systems have been taken out of use without the system infrastructure being removed from its original location. Such metal stocks in hibernation thus constitute potential resource reservoirs accessible for rec...

A small flying machine based upon a new mechanism was realized. The flying machine driven by magnetic torque had hard magnetic rims as wings and a soft magnetic wire as a body, respectively. The wing has two hinges, which create different drag during up and down strokes, and produced lifting force. Shape magnetic anisotropy of the body stabilized the attitude, The flying machine flew without po...
