Energy is a peer-reviewed academic journal covering research on energy engineering that was established in 1976. It is published by Elsevier and the editor-in-chief is Henrik Lund (Aalborg University). According to the Journal Citation Reports, the journal has a 2013 impact factor of 4.159, ranking it 13th out of 83 journals in the category "Energy & Fuels" and second out of 55 journals in "Thermodynamics".
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.
Corp may refer to:
A corporation is a company or group of people authorized to act as a single entity (legally a person) and recognized as such in law. Early incorporated entities were established by charter (i.e. by an ad hoc act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration.
Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered into two kinds: by whether or not they can issue stock, or by whether or not they are for profit.
Where local law distinguishes corporations by ability to issue stock, corporations allowed to do so are referred to as "stock corporations", ownership of the corporation is through stock, and owners of stock are referred to as "stockholders." Corporations not allowed to issue stock are referred to as "non-stock" corporations, those who are considered the owners of the corporation are those who have obtained membership in the corporation, and are referred to as a "member" of the corporation.
The Central Oregon and Pacific Railroad (reporting mark CORP) is a Class II railroad operating between Northern California and Eugene, Oregon, United States. It was previously a mainline owned by the Southern Pacific Railroad (SP) between Eugene and Weed, California (north of Redding, California) via Medford, Oregon. SP sold the route on December 31, 1994, in favor of using its route to Eugene via Klamath Falls, Oregon and Cascade Summit.
The mainline of the CORP is 389 miles (626 km). Traffic is estimated at 17,000 cars per year, consisting mainly of logs, lumber products, and plywood. CORP is a subsidiary of Genesee & Wyoming, which acquired the railroad as part of its acquisition with RailAmerica in late 2012. Until 2007, CORP also operated the 136-mile (219 km) Coos Bay branch, another line once owned by the SP.
On May 17, 2007, CORP was awarded a Silver E. H. Harriman Award in Group C for the railroad's safety record in 2006. This award marked the first time a RailAmerica-owned railroad has earned a Harriman award.
