Problem: Information:  - A smartphone is a mobile phone (also known as cell phones or cell mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. Smartphones, which are usually pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera. Smartphones can access the Internet and can run a variety of third-party software components ("apps" from Google Play, Apple App Store, etc). They typically have a color display with a graphical user interface that covers more than 76% of the front surface. The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features.  - id Software LLC (formerly id Software, Inc., ; see Company name) is an American video game developer headquartered in Dallas, Texas. The company was founded on February 1, 1991, by four members of the computer company Softdisk, programmers John Carmack and John Romero, game designer Tom Hall, and artist Adrian Carmack (no relation to John Carmack). Business manager Jay Wilbur was also involved.  - Doom 3 (stylized as DOOM) is a science fiction first-person shooter video game developed by id Software and published by Activision. "Doom 3" was first released for Microsoft Windows on August 3, 2004. The game was later adapted for Linux, as well as being ported by Aspyr Media for Mac OS X. Developer Vicarious Visions ported the game to the Xbox console (now backwards compatible to the Xbox 360), releasing it on April 3, 2005. British developers Splash Damage also assisted in design for the multiplayer elements of the game.  - Doom RPG is a mobile phone game developed by Fountainhead Entertainment . It combines the Doom first - person shooter franchise with role - playing video game elements . The storyline incorporates many similar events of Doom 3 , but involves different characters than those in the third game . The website for Doom RPG does state that the protagonist in Doom RPG is the same character from Doom , Doom II , and Doom 3 .  - A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Most modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are often also called "cellular telephones" or "cell phones". In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and digital photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones.

Problem: Information:  - Mullard Radio Astronomy Observatory (MRAO) is home to a number of large aperture synthesis radio telescopes, including the One-Mile Telescope, 5-km Ryle Telescope, and the Arcminute Microkelvin Imager.   - The Fourth Cambridge Survey ( 4C ) is an astronomical catalogue of celestial radio sources as measured at 178 MHz using the 4C Array . It was published in two parts , in 1965 ( for declinations +20 to +40 ) and 1967 ( declinations -7 to + 20 and +40 to +80 ) , by the Radio Astronomy Group of the University of Cambridge . References to entries in this catalogue use the prefix 4C followed by the declination in degrees , followed by a period , and then followed by the source number on that declination strip , e.g. 4C - 06.23 . The 4C Array , which used the technique of aperture synthesis , could reliably position sources with flux densities of around 2 Jy , to within about 0.35 arcmin in Right ascension and 2.5 arcmin in declination .  - The Equator usually refers to an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about long; some 78.7% lies across water and 21.3% over land.  - The 4C Array is a cylindrical paraboloid radio telescope at the Mullard Radio Astronomy Observatory, near Cambridge, England. It is similar in design to the Molonglo Observatory Synthesis Telescope. It is 450 m long, 20 m wide, with a second, moveable element (now mostly removed; some of it is still visible, beyond COAST). The first large aperture synthesis telescope (1958), it was also the first new instrument to be built at Lord's Bridge, after the Observatory was moved there in 1957, and needed of reflector wire (since removed). The 4C operated at 178 MHz (1.7 m), and located nearly 5000 sources of the 4C (4th Cambridge) catalogue published in 1965 and 1966, which helped establish the evolution of the radio galaxy population of the universe. The telescope is now inoperable.  - In astronomy and celestial navigation, the hour angle is one of the coordinates used in the equatorial coordinate system to give the direction of a point on the celestial sphere. The hour angle of a point is the angle between two planes: one containing the Earth's axis and the zenith (the meridian plane), and the other containing the Earth's axis and the given point (the hour circle passing through the point).  - In astronomy, declination (abbreviated dec; symbol ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle. Declination's angle is measured north or south of the celestial equator, along the hour circle passing through the point in question.  - In astronomy, the hour circle of a celestial object is the great circle through the object and the celestial poles. It is perpendicular to the celestial equator. The declination of an object as observed on the celestial sphere is the angle measured along the hour circle of that object to the celestial equator. In other words, it is analogous to meridians or longitudes on a globe. A meridian on the celestial sphere matches an hour circle at any time. So called because the angle between the planes of the hour circles (or the difference in longitudes) of two objects is sometimes measured in hours (or hours, minutes, and seconds), one revolution (360°) being equivalent to 24 hours, or 1 hour being equivalent to 15°.
