Der (Sumerian: ^ALUDi-e-ir) was a Sumerian city-state at the site of modern Tell Aqar near al-Badra in Iraq's Wasit Governorate. It was east of the Tigris River on the border between Sumer and Elam. Its name was possibly Durum.

History

Der was occupied from the Early Dynastic period through Neo-Assyrian times. The local deity of the city was named Ishtaran, represented on Earth by his minister, the snake god Nirah. In the late 3rd millennium, during the reign of Sulgi of the Third Dynasty of Ur, Der was mentioned twice. The Sulgi year name 11 was named "Year Ishtaran of Der was brought into his temple", and year 21 was named "Year Der was destroyed". In the second millennium, Der was mentioned in a tablet discovered at Mari sent by Yarim-Lim I of Yamhad; the tablet includes a reminder to Yasub-Yahad king of Der about the military help given to him for fifteen years by Yarim-Lim, followed by a declaration of war against the city in retaliation for what Yarim-Lim described as evil deeds committed by Yasub-Yahad.

Club career

Early years

Born in Bissau, Guinea-Bissau, Éder moved to Portugal as a child, and started playing football with Associação Desportiva e Cultural da Adémia in the Coimbra District at the age of 11. He made his senior debut with F.C. Oliveira do Hospital and G.D. Tourizense, the latter in the third division and the farm team of Académica de Coimbra.

Académica

Éder made his top level debut for Académica on 24 August 2008, in a 0–1 away loss against C.F. Estrela da Amadora. He scored his first goal for the club at the end of the season, netting the Students equalizing goal in an eventual 3–1 victory over Associação Naval 1º de Maio.

Éder (Italian footballer)

Éder Citadin Martins, simply known as Éder (born 15 November 1986), is a Brazilian-born Italian professional footballer who plays as a striker for Italian club Internazionale, on loan from Sampdoria, and for the Italian national team.

A Brazilian of Italian descent, he made his debut for Italy in March 2015, and scored two goals in their successful qualification campaign for UEFA Euro 2016.

Club career

Frosinone

Éder signed for Frosinone in a co-ownership deal for a fee of €600,000 in June 2008 following a loan spell during the second half of the 2007–08 Serie B season.

Return to Empoli

Empoli bought back Éder from Frosinone in June 2009 for €2.42 million following an impressive Serie B season from the striker. He scored 4 goals in one Serie B game on 15 April 2010, two of which were penalties, in a 5–2 victory for Empoli over Salernitana.

Brescia

On 20 August 2010, he signed a 1+4 year contract with Serie A newcomers Brescia, for an undisclosed fee, meaning that Éder would join Brescia on loan for the first year. Brescia later revealed in its financial report that the loan fee was €1.8 million.

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.

Energy (Keri Hilson song)

"Energy" is the debut single by American recording artist Keri Hilson. The song was written and produced by The Runaways, consisting of Louis Biancaniello, Sam Watters, Rico Love, and Wayne Wilkins, for her studio album In a Perfect World… (2009).

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. Billboard Hot 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.

Background

"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.
