Afonso Poyart (born 1979) is a Brazilian film director, producer and writer.
 He made his feature film directorial debut with the 2012 action "2 Coelhos" ("Lit: 2 Rabbits") and later directed the film "Solace", starring Anthony Hopkins.
Afflicted is a 2013 Canadian found footage horror film that was written and directed by Derek Lee and Clif Prowse, and is their feature film directorial debut.
 It had its world premiere on September 9, 2013 at the Toronto International Film Festival, where it won a special jury citation for Best Canadian First Feature Film.
 Lee and Prowse also star in "Afflicted" as two friends whose goal to film themselves traveling the world is cut short when one of them contracts a mysterious disease.
Arnold is an unbiased, physically based, ray tracing 3D rendering application created by the company Solid Angle.
 Notable films that have used Arnold include "Monster House", "Cloudy with a Chance of Meatballs", "Alice in Wonderland", "Thor", "", "", "The Avengers", "Red Tails", "", "Space Pirate Captain Harlock", "Elysium", "Pacific Rim" and "Gravity".
You Can't Kill Stephen King is a 2012 American comedy horror film that was directed by Monroe Mann, Ronnie Khalil, and Jorge Valdés-Iga, and is the directorial debut of Khalil and the feature film directorial debut of Mann.
 The film had its world premiere on 14 April 2012 at the Lewiston Auburn Film Festival and was later released to DVD on 9 December 2014 through Big Screen Entertainment Group.
 The film follows a group of friends that decide to visit the area horror author Stephen King lives, but find themselves threatened with their own potential deaths.
Brandon Dickerson is an American writer, director, and producer whose work includes film, music video, documentary film, and television commercials.
 He made his feature film directorial debut with the 2011 feature film "Sironia", which won the Audience Award at the 2011 Austin Film Festival in October 2011 before its release through Filmbuff.
 His second feature film as writer-director, "Victor", is set for release in 2017 as is his documentary film "A Single Frame".
Red Tails is a 2012 American war film directed by Anthony Hemingway in his feature film directorial debut, and starring Terrence Howard and Cuba Gooding Jr. The film is about the Tuskegee Airmen, a group of African-American United States Army Air Forces (USAAF) servicemen during World War II.
 The characters in the film are fictional, although based on real individuals.
 The film was produced by Lucasfilm and released by 20th Century Fox.
 This was Cuba Gooding Jr.'s first theatrically released film in five years since his starring role in 2007's "Daddy Day Camp".
Chimères (English: "Chimeras") is a 2013 horror film and the feature film directorial debut of Olivier Beguin.
 The movie had its world premiere on July 5, 2013 at the Neuchâtel International Fantastic Film Festival, where it won a special mention for best feature film.
 It stars Yannick Rosset as a young man that ends up contracting vampirism after receiving a blood transfusion.
In radiometry, radiance is the radiant flux emitted, reflected, transmitted or received by a given surface, per unit solid angle per unit projected area.
 Spectral radiance is the radiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
 These are "directional" quantities.
 The SI unit of radiance is the watt per steradian per square metre (), while that of spectral radiance in frequency is the watt per steradian per square metre per hertz () and that of spectral radiance in wavelength is the watt per steradian per square metre, per metre ()—commonly the watt per steradian per square metre per nanometre ().
 The microflick is also used to measure spectral radiance in some fields.
 Radiance is used to characterize diffuse emission and reflection of electromagnetic radiation, or to quantify emission of neutrinos and other particles.
 Historically, radiance is called "intensity" and spectral radiance is called "specific intensity".
 Many fields still use this nomenclature.
 It is especially dominant in heat transfer, astrophysics and astronomy.
 "Intensity" has many other meanings in physics, with the most common being power per unit area.
Radar engineering details are technical details pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
 This includes field of view in terms of solid angle and maximum unambiguous range and velocity, as well as angular, range and velocity resolution.
 Radar sensors are classified by application, architecture, radar mode, platform, and propagation window.
Titus is a 1999 Italian-American-British film adaptation of William Shakespeare's revenge tragedy "Titus Andronicus", about the downfall of a Roman general.
 Starring Anthony Hopkins and Jessica Lange, it was the first theatrically-released feature film adaptation of the play.
 The film was made by Overseas Filmgroup and Clear Blue Sky Productions and released by Fox Searchlight Pictures.
 It was the film directorial debut of Julie Taymor, who co-produced and wrote the screenplay.
 It was produced by Jody Patton, Conchita Airoldi and executive produced by Paul G. Allen.
