In signal processing, the energy of a continuous-time signal x(t) is defined as
the energy of a discrete-time signal x(t) is defined as
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.
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.
"Energy" is the second single by Canadian rapper Drake from his fourth commercial release If You're Reading This It's Too Late.
"Energy" contains samples from Eazy-Duz-It performed by Eazy-E and Ridin Spiners performed by Three 6 Mafia. Energy was produced by Boi-1da and OB O'Brien. According to WhoSampled the song samples the score of an episode of The O.C..
"Energy" received acclaim from music critics with many calling it the best song of the album. Ryan Dombal of Pitchfork gave the song a positive review and named it "Best New Track", stating "The song isn't aimed to any rappers or pop stars, not Kendrick Lamar, Big Sean or Tyga, but the song lines are dangerous."
The video of "Energy" was released on Apple Music and users with iTunes and registered Apple Music account can watch this video.
A congress is a formal meeting of the representatives of different nations, constituent states, independent organizations (such as trade unions), or groups.
The term was chosen for the Continental Congress to emphasize the status of each colony represented there as a self-governing unit. Subsequent to the use of congress by the U.S. legislature, the term has been adopted by many states within unions, and by unitary nation-states in the Americas, to refer to their legislatures.
The following congresses were formal meetings of representatives of different nations:
Countries with Congresses and presidential systems:
Congress (Dolo), a group that split away from Indian National Congress in Arunachal Pradesh. Congress (D) was founded July 25, 2003. Together with Gegong Apang of Arunachal Congress, Congress (D) formed a state government. On August 30 Congress (D) merged with Bharatiya Janata Party.
The Indian National Congress (Urs) was a breakaway faction of the Congress (I) led by D. Devaraj Urs. It broke away from the parent party in 1978 following Indira Gandhi's drubbing in the 1977 General Elections. Urs took with him many legislators from Karnataka, Kerala, Maharashtra and Goa including future Union Ministers and Chief Ministers, Yashwantrao Chavan, Dev Kant Baruah, Kasu Brahmananda Reddy, A.K. Antony, Sharad Pawar, Sarat Chandra Sinha, Priyaranjan Das Munshi and K.P. Unnikrishnan.
Subsequently Devaraj Urs joined Janata Party; Yashwantrao Chavan, Brahmananda Reddy, and Chidambaram Subramaniam joined Congress (Indira); and A.K. Antony split from Congress (Urs) to form Congress (A) in Kerala. When Sharad Pawar took over the party presidency in October 1981, the name of the party was changed to Indian Congress (Socialist)

Russian President Vladimir Putin is expected to meet his Turkish counterpart Recep Tayyip Erdogan on the sidelines of the World Energy Congress in Istanbul. More than 200 energy leaders from 85 countries are there to talk about energy policies. They are likely to discuss implementing the Turkish Stream gas pipeline, which would see gas delivered directly from Russia to Turkey. The project had been suspended for several months after the downing of a Russian jet near the border with Syria last year.

The 24th World Energy Congress brought together international energy stakeholders, including governments, private and state corporations, academia and media. With over 15,000 participants, the Congress welcomed over 300 high-level speakers, 70 ministers, 500 CEOs, 1100 media with an 40,000 sqm exhibition space that featured the entire energy spectrum. The programme was divided into four thematic tracks for each public day of Congress. Watch this video to learn what day 4 was all about. #Energy4Prosperity
This animated video, "Nuclear Energy: Turn it On," was shown at NEI's booth during the 2010 World Energy Congress in Montreal.
Talented young energy professionals declared their Vision for the Future of the energy sector during the closing ceremony of the 23rd World Energy Congress in Istanbul on 13 October 2016. Having combined their efforts to define an overall Future Energy Leaders (FEL) vision for years to come, the members of the FELs felt optimistic in being able to offer solutions to the challenges facing the energy sector in order to contribute to a sustainable future.
