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.
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.
'Bangla (Bengali:বাংলা) may be a transliteration of either Bengal (a geographical and ethno-linguistic region in South Asia) or Bengali (an adjective referring to something of, from, or related to Bengal) and may also refer to:
Bangla is a folk-rock band from Bangladesh. Formed by the popular indie musicianArnob, Bangla mainly blends the traditional Bangladeshi folk genres like Baul, Lalon together with western flavours like jazz, blues, rock etc. The band released its first album Kingkortobbobimurho in 2002. Over the years, the band has emerged as a prominent music group in the country and became one of the most sought after bands, especially among the urban youth listeners.
The formation of the band dates back to the late '90s when Arnob was a student of Visva-Bharati University at Santiniketan. Due to his interest in music, he casually formed a band with his friends in Santineketan in a motive to spread out Bengali folk songs. One day, Anusheh came to visit Shantiniketan, who was a family friend of Arnob. Anusheh, who was well trained on Indian Classical Music, subsequently accepted the invitation of Arnob and became the lead vocalist. On their visit to Lalon's shrine in Kushtia, Arnob and Anusheh met Buno, a close friend of Anusheh and a bassist. The trio performed together at a public concert in Kolkata Book Fair in 1999. Their performance received good feedback from the audience. The same year, Arnob moved to Dhaka. The band was then joined by Kartik, former guitarist of Prachayanat. and Shantanu on drums. Thus they came to be known as the band "Bangla". A year later, Nazrul, also an acquaintance of Anusheh, joined as the Dhol player.
Rupam Islam. We had once been for a Fossils concert in Kolkata. It had been an almost religious experience, because imagine the sort of fervour that a gospel band - playing rousing music in praise of the Lord after Sunday mass in a church - might elicit from the pious congregation. That's the sort of energy we had seen around us while watching the Bangla rock band live ...The audience at a Fossils concert ... On March 15, 8.30 pm ... ....
Four famous Sikh shrines in Delhi including Rakab Ganj and Bangla Sahib Gurudwaras will go green by employing solar energy to meet their daily power needs from April ... Harjit Singh, who is the head of the renewable energy wing of DSGMC, said the capacity of the project will be increased from 1 MW to 2 MW to meet growing future demands of these shrines....
