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.

Aiko, Princess Toshi

Princess Aiko, The Princess Toshi (敬宮愛子内親王, Toshi-no-miya Aiko Naishinnō, born 1 December 2001) is the only child of Naruhito, Crown Prince of Japan and his wife, Masako.

Name

In a break with tradition, the name of the princess was chosen by her parents, instead of by the Emperor. It was selected from the teachings of the Chinese philosopher Mencius. In clause 56 of Li Lou II, Mencius said "One who loves the others will be constantly loved by them; one who respects others will be constantly respected by them. (愛人者人恆愛之，敬人者人恆敬之。)"

Aiko, the princess's personal name, is written with kanji character for "love (愛)" and "child (子)" and means "a person who loves others." The princess also has an imperial title, Princess Toshi (敬宮 toshi-no-miya) which means "a person who respects others." This formal title will be dropped if she marries a commoner.

Personal life

Princess Aiko began her education at Gakushuin Kindergarten on April 3, 2006. She left kindergarten on March 15, 2008. On 18 March 2014, Princess Aiko finished at Gakushuin elementary school and on 6 April 2014 she entered Gakushuin Girl's Junior High-school.

Music career

In April, 1996, Aiko became a radio host of FM Osaka after graduating from the college. She released a CD which she produced independently with her friends of the college in August. She participated in "The 5th Music Quest Japan Final" on October 10, and was awarded the Excellence Award shared with Ringo Shiina. She released an EP on an independent label in 1997, followed by a single and a mini-album in 1998.

In July, 1998, Aiko debuted on a major label with her first single, "Ashita", which was used as the theme song for the movie Shinsei Toire no Hanako-san.

In 2000, her second album, Sakura no Ki no Shita, reached number one in the Oricon weekly charts, with the total CD sales amounting to 1.4 million copies. Her sixth single, "Boyfriend", sold over 500,000 copies and became her best-selling CD single. She made her first appearance in NHK's 2000 Kohaku Uta Gassen.
