Power and Electrical Engineering

“Hydrogen power engineering — is energy of the future”, efforts are being undertaken in the US, Europe and Russia to implement the above postulate. We have tried to calculate the quantity of hydrogen needed to transfer to it all transport of big cities, i.e. the quantity that will be required to replace engine fuels. All calculations were based on maximum coefficients of efficiency and the most optimistic figures. The conclusions made from the obtained figures seem interesting not only for scientis

In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. “We are still at the beginning,” says Tonica Valla, a physicist at the U.S. Department of Energy’s Brookhaven National Laboratory, who will give a talk on his group’s latest results at the American Physical Society meeting in Baltimore, Maryland on Thursday,

Grocers, florists and even pharmacists may soon have a better way to monitor the quality of the products they get from suppliers: a sensor that will tell how long before a product spoils or passes its expiration date.

A team of University of Florida engineering students has designed and built a prototype of the new smart sensor, which can also record and wirelessly transmit information to retailers about when and where glitches occur as a product is being shipped.

Fatronik has launched the most rapid robot in the world at the BIEMH (International Machine-Tool Biennial) in Bilbao.

What is involved here is a high-performance handling robot the structure of which is basically four actuators working in a co-ordinated manner with the goal of achieving maximum dynamic performances.

The robot has four degrees of freedom, displacements along three translations and rotates on its vertical axis. It is a cylinder with a diameter of 1200mm an

ANTENNESSA of France has launched the INSITE box, a cheap and efficient electromagnetic-field continuous-measuring box. The INSITE box’s technology allows for continuous selective measuring on nine frequency bands (FM, GSM, UMTS, FM, TV3, TV4&5 and DCS). The box uses EME SPY dosimeter technology (patented by France Telecom and ANTENNESSA), based on a filtering principle that enables the emission bands to be identified. The measurements come to between 0.05V/m and 5V/m.

Probabilistic system on chip technology reduces energy consumption by a factor of more than 500 for some applications

Researchers at the Georgia Institute of Technology announce energy savings by a factor of more than 500 in simulations with their ultra energy efficient embedded architecture based on Probabilistic CMOS (PCMOS). The research team’s PCMOS devices take advantage of noise, currently fabricated at the quarter-micron (0.25 micron) level, and uses probability to extract
