In the field of heat transfer, intensity of radiation Failed to parse (Missing texvc executable; please see math/README to configure.): I

is a measure of the distribution of radiant heat flux per unit area and solid angle, in a particular direction, defined according to
Failed to parse (Missing texvc executable; please see math/README to configure.): dq = I\, d\omega\, \cos \theta\, dA


where

  • Failed to parse (Missing texvc executable; please see math/README to configure.): dA
is the infinitesimal source area 
  • Failed to parse (Missing texvc executable; please see math/README to configure.): dq
is the outgoing heat transfer from the area Failed to parse (Missing texvc executable; please see math/README to configure.): dA
  • Failed to parse (Missing texvc executable; please see math/README to configure.): d\omega
is the solid angle subtended by the infinitesimal 'target' (or 'aperture') area Failed to parse (Missing texvc executable; please see math/README to configure.): dA_a
  • Failed to parse (Missing texvc executable; please see math/README to configure.): \theta
is the angle between the source area normal vector and the line-of-sight between the source and the target areas.

Typical units of intensity are W·m-2·sr-1.

Intensity can sometimes be called radiance, especially in other fields of study.

The emissive power of a surface can be determined by integrating the intensity of emitted radiation over a hemisphere surrounding the surface:

Failed to parse (Missing texvc executable; please see math/README to configure.): q = \int_{\phi=0}^{2\pi} \int_{\theta=0}^{\pi/2} I \cos \theta \sin \theta d\theta d\phi


For diffuse emitters, the emitted radiation intensity is the same in all directions, with the result that

Failed to parse (Missing texvc executable; please see math/README to configure.): E = \pi I


The factor Failed to parse (Missing texvc executable; please see math/README to configure.): \pi

(which really should have the units of steradians) is a result of the fact that intensity is defined to exclude the effect of reduced view factor at large values Failed to parse (Missing texvc executable; please see math/README to configure.): \theta
note that the solid angle corresponding to a hemisphere is equal to Failed to parse (Missing texvc executable; please see math/README to configure.): 2\pi
steradians.

Spectral intensity Failed to parse (Missing texvc executable; please see math/README to configure.): I_\lambda

is the corresponding spectral measurement of intensity; in other words, the intensity as a function of wavelength.

  • List of Death Note episodes

    Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.

    A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.

    Transfer (public transit)

    A transfer allows the rider of a public transportation vehicle who pays for a single-trip fare to continue the trip on another bus or train. Depending on the network, there may or may not be an additional fee for the transfer. Historically, transfers may have been stamped or hole-punched with the time, date, and direction of travel to prevent their use for a return trip. More recently, magnetic or barcoded tickets may be recorded (as on international flights) or ticket barriers may only charge on entry and exit to a larger system (as on modern underground rail networks).

    Some public transport companies may honor transfers purchased from another company with connecting service.

    Intensity!

    Intensity! is the second studio album released by Croatian surf rock band The Bambi Molesters. The album was recorded in December of 1998 and was released in 1999.

    Background

    In 1999, the band signed to Dancing Bear Records. The release of the album on the label prompted the band to tour all of Europe, alongside acts such as Man or Astro-man?, The Flaming Sideburns, and The Cramps. As their reputation for live shows expanded, radio stations in America and the United Kingdom began playing their music, exposing them to a wider audience. They also released music videos of "The Wedge" and "Bikini Machines" to promote the album.

    In 1999, they performed as an opening act for R.E.M. during their European promotional tour for the album Up. R.E.M. guitarist Peter Buck, having gone to see the band play beforehand, was significantly impressed by the band's performance, and offered to perform on later albums. Buck appeared as a guest musician on the Bambi Molesters' 2001 album, Sonic Bullets: 13 from the Hip, where he contributed two guitar solos.

    Intensity (novel)

    Intensity is a novel by the best-selling author Dean Koontz, released in 1995.

    Plot summary

    Chyna Shepard is a college student visiting the family of her friend, Laura Templeton, for a long weekend. Chyna, who was abused and neglected by her mother as a child, finds the Templeton house provides something she has yearned: acceptance. This comes to a violent end when Edgler Vess, a serial killer, breaks into the house in the night and methodically kills all of the occupants except Laura and Chyna.

    Chyna hides from him under her bed and waits until he goes downstairs. She searches the house and finds Laura's father shot and tied to a toilet seat, and the mother stabbed to death in the shower. Chyna encounters Vess on the stairs eating a spider before she sneaks into Laura's room. She finds Laura tied up and raped. Chyna sneaks away, promising to return. Before she can intervene, Vess kills Laura and takes her to his motor home. Chyna hears Laura screaming and runs upstairs intending to attack Vess with a knife. Unaware Laura is dead, Chyna sneaks aboard the motor home and finds her friend's corpse. Before she can escape, Vess drives away. Chyna hides in a back room, planning to escape at the earliest opportunity. When he stops at a gas station, she sneaks out of the motor home, and heads inside the gas station to find a phone. Chyna surreptitiously watches Vess boast to the gas station clerks that he is holding a young girl, Ariel, prisoner in his basement, before he kills them and drives away. Chyna feels compelled to follow Vess and help free the girl. She takes an attendant's car, and follows Vess. Chyna passes Vess while traveling through a state park and crashes her car into a redwood tree. While Vess gets out to investigate, Chyna sneaks on board the motor home.

    Intensity (Charles Earland album)

    Intensity is an album by organist Charles Earland which was recorded in 1972 and released on the Prestige label.

    Reception

    Allmusic awarded the album 4 stars stating "Even if the performances on Intensity weren't excellent, this Charles Earland session would be required listening for jazz historians because it marked the last recorded documentation of Lee Morgan. Only two days after Intensity was recorded at Rudy Van Gelder's famous New Jersey studio on February 17, 1972, the influential trumpeter was shot and killed by a girlfriend at the age of 33. Refusing to confine himself to hard bop, Morgan was exploring soul-jazz and fusion during the last years of his life -- and his enthusiasm for soul-jazz is hard to miss".
