Energy (signal processing)
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
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.

Seven Year Itch (Collective Soul album)
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 (Drake song)
"Energy" is the second single by Canadian rapper Drake from his fourth commercial release If You're Reading This It's Too Late.
Composition
"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..
Critical reception
"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."

Synopsis
Dessert
Dessert (/dᵻˈzɜːrt/) is a course that concludes a main meal. The course usually consists of sweet foods and beverages, but may include coffee, cheeses, nuts, or other savory items. In some parts of the world there is no tradition of dessert to conclude a meal.
The term dessert can apply to many foods, such as cakes, tarts, cookies, biscuits, gelatins, pastries, ice creams, pies, puddings, custards, and sweet soups. Fruit is also commonly found in dessert courses because of its naturally occurring sweetness. Some cultures sweeten foods that are more commonly savory to create desserts.
Etymology
The word "dessert" originated from the French word desservir, meaning "to clear the table." Its first known use was in 1600, in a health education manual entitled Naturall and artificial Directions for Health, which was written by William Vaughan. In his A History of Dessert (2013), Michael Krondl explains it refers to the fact dessert was served after the table had been cleared of other dishes. The term dates from the 14th century but attained its current meaning around the beginning of the 20th century when "service à la française" (setting a variety of dishes on the table at the same time) was replaced with "service à la russe" (presenting a meal in courses.)"
Desert (philosophy)
Desert (/dᵻˈzɜːrt/) in philosophy is the condition of being deserving of something, whether good or bad.
Nomenclature
The word is related to justice, revenge, blame, punishment and many topics central to moral philosophy, also "moral desert". In the English language, the word "desert" with this meaning tends to be a rather uncommon word colloquially where it is almost exclusively collocated in the popular phrase one's just deserts (e.g. "Although she was not at first arrested for the crime, she later on received her just deserts.").
In ordinary usage, to deserve is to earn or merit a reward; in philosophy, the distinction is drawn in the term desert to include the case that which one receives as one's just deserts may well be unwelcome, or a reward. For example, if one scratches off a winning lottery ticket, one may be entitled to the money, but one does not necessarily deserve it in the same way one would deserve $5 for mowing a lawn, or a round of applause for performing a solo.
2010 Desert 400
The 2010 Desert 400 was the second event of the 2010 V8 Supercar Championship Series. It was held on the weekend of February 25–27 on Bahrain International Circuit, in Manama, Bahrain. This was first time the event was held since 2008, and for the first time the V8 Supercars used the full Grand Prix Circuit, as used for the Bahrain Grand Prix, rather than the previously Paddock Circuit the Australian sedans used from 2006–2008.
Defending series champion Jamie Whincup made a clean sweep of the V8 Supercar Middle-East branch of the championship. Whincup followed his two wins at the 2010 Yas V8 400 with two more wins to hold a perfect 600 points from the first four races of the season. Mark Winterbottom was best of the rest throughout the weekend with a pair of second positions and Craig Lowndes and Shane Van Gisbergen shared the third places.
