Alliander (Arnhem, Netherlands) Alliander, the largest network company in the Netherlands, is paving the way for increased adoption and usage of electric vehicles by working with other companies in their ecosystem to provide 10,000 charging points throughout the country by 2012. CenterPoint Energy (Houston, TX) CenterPoint Energy Houston Electric is a transmission and distribution company serving approximately 2.2 million consumers in the Houston area, the fourth largest city in the U.S, and operates in an electric deregulated market. The company’s Energy InSight Center was one of the first demonstration centers in the world to show the smart meter and outage restoration benefits that can be realized through smart grid technologies. CPFL (Sao Paulo, Brazil) CPFL is the largest private company in the Brazilian electric sector and the first company to negotiate carbon credits. CPFL has 7.2 million customers distributed among its 8 distribution utilities. Smart Grid - Ideas - United States
Abstract: Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the poor performance that gave early video filters a bad reputation. High-performance op amps and specialized software for the PC enable the design of wide-bandwidth active filters, but those advantages do not address the requirements of any specific application. For video filters, the particular application and signal format add nuance to each circuit design. The two major video applications follow. Active Filters for Video

Test of building smart sensors yields big energy savings (PhysOrg.com) -- To reduce energy consumption in commercial buildings, computer scientists at the University of California, San Diego have come up with a way to use real-time occupancy sensors and computer algorithms to create smart heating, ventilation and air-conditioning (HVAC) systems. Based on early test results, the software- and sensor-based solution produced electrical energy savings of between 9.54 and 15.73 percent on their test deployment on one floor of a 5-floor campus building. “It’s clear that sensors and computing are key to reducing the demand for electricity in office buildings,” said Yuvraj Agarwal, a research scientist in UC San Diego’s Computer Science and Engineering (CSE) department. “Based on the test deployment, we estimate 40-50 percent in energy savings if we deployed our system across the entire CSE building.
“Smart grid” generally refers to a class of technology people are using to bring utility electricity delivery systems into the 21st century, using computer-based remote control and automation. These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from the power plants and wind farms all the way to the consumers of electricity in homes and businesses. They offer many benefits to utilities and consumers -- mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices. For a century, utility companies have had to send workers out to gather much of the data needed to provide electricity. The workers read meters, look for broken equipment and measure voltage, for example.

Среди прочего, все ученые работают с литературой. Они ее читают (sic!), а когда пишут статьи, обзоры или книги - то ссылаются на источники. В науке не принято пользоваться агенством ОБС, здесь все четко: если что-то утверждаешь, будь добр, приведи основания, почему ты это пишешь. pochekailov - Программы для работы с литературой
A Quick Sine Wave Generator
DFT of four period sin(x) The magnitude graph of sin(x), above, exhibits the embarrassment of DFT leakage. Instead of having a signal magnitude 1.0 value at an x-axis location this case corresponds to the number of sin(x) periods, there is a magnitude that is slightly less than 1.0 and several sub-magnitudes. For sin(x) this is not a big problem, since it is easy to distinguish the major component of the signal. However, if it is a complex signal, which smaller components, the smaller components may be obscured by the DFT leakage. The Discrete Fourier Transform (DFT)
