Federal-style architecture is the name for the classicizing architecture built in North America between c. 1780 and 1830, and particularly from 1785 to 1815, mostly from the two brothers, Robert Adam and James Adam. This style shares its name with its era, the Federal Period. The name Federal style is also used in association with furniture design in the United States of the same time period. The style broadly corresponds to the classicism of Biedermeier style in the German-speaking lands, Regency style in Britain and to the French Empire style.
In the early American republic, the founding generation consciously chose to associate the nation with the ancient democracies of Greece and the republican values of Rome. Grecian aspirations informed the Greek Revival, lasting into the 1850s. Using Roman architectural vocabulary, the Federal style applied to the balanced and symmetrical version of Georgian architecture that had been practiced in the American colonies' new motifs of neoclassical architecture as it was epitomized in Britain by Robert Adam, who published his designs in 1792.
the energy of a discrete-time signal x(t) is defined as
Relationship to energy in physics
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.
The track was released as the first single from the singer's debut in the United States on May 27, 2008. Although being released worldwide it initially only charted in New Zealand at number two and only managed to reach top thirty on the U.S. BillboardHot R&B/Hip-Hop Songs and Hot Dance Club Play charts.
Generally well received by music critics, it was named sixty-first on The Top 144 Songs of 2008 listing by Blender magazine.
"Energy" was written and produced by The Runaways. It was also recorded by The Runaways at Homesite 13 studios in Novato, California. and Hilson stated that she wanted to prove that she can be successful even without collaborations and guest vocalists and so it was announced "Energy" would be released as the next worldwide single following the success of "Knock You Down". The song was released on September 14, 2009 in the UK. On September 25, 2009 she appeared live on breakfast TV show GMTV in the UK where she performed the single. That same day, she appeared on BBC Radio 1's Live Lounge where she performed a stripped version of "Energy" as well as a gospel cover version of "Supernova" originally sung by Mr Hudson and Kanye West.
On September 18, 2001, Collective Soul released their greatest hits compilation Seven Year Itch: Greatest Hits, 1994-2001 (stylized as 7even Year Itch). The compilation includes songs recorded from 1994 to 2001 and included two new tracks; "Next Homecoming" and "Energy". Seven Year Itch received decent reviews and was relatively successful It sold 225,000 copies in the first year after its release and reached number fifty on the Billboard 200; in Canada, it reached number nine on its albums chart and went platinum. All the songs in Seven Year Itch had charted in the US on the Billboard Hot 100, Mainstream Rock Tracks, or the Modern Rock Tracks chart, except for "Energy", which debuted in this compilation.
The compilation has sold over 500,000 copies. It saw a resurgence in sales after Collective Soul began putting out albums on their own independent label, El Music Group, beginning in 2004.
Seven Year Itch was the last album Collective Soul released through Atlantic Records and their last album to feature guitarist Ross Childress, who had been with the band since its 1993/1994 debut.
