In grammar, a modifier is an optional element in phrase structure or clause structure. A modifier is so called because it is said to modify (change the meaning of) another element in the structure, on which it is dependent. Typically the modifier can be removed without affecting the grammar of the sentence. For example, in the English sentence This is a red ball, the adjective red is a modifier, modifying the noun ball. Removal of the modifier would leave This is a ball, which is grammatically correct and equivalent in structure to the original sentence.
Other terms used with a similar meaning are qualifier (the word qualify may be used in the same way as modify in this context), attribute, and adjunct. These concepts are often distinguished from complements and arguments, which may also be considered dependent on another element, but are considered an indispensable part of the structure. For example, in His face became red, the word red might be called a complement or argument of became, rather than a modifier or adjunct, since it cannot be omitted from the sentence.
"Tempest" is the second single by Sacramento, California-based alternative metal band Deftones, from their seventh studio album, Koi No Yokan. The song debuted on PureVolume's official website on October 3, 2012 along with a video featuring band members Chino Moreno and Sergio Vega giving some insight regarding the track. The song's lyrical content is representative of the supposed end of the world that would have occurred on December 21, 2012, according to various myths related to the Mayan calendar. It was featured in the trailer for the film Jack the Giant Slayer and featured in Furious 7.
Peaking at No. 3 on the US Hot Mainstream Rock Tracks, Tempest became Deftones' most successful single on that chart, surpassing "Change (In the House of Flies)", which peaked at No. 9 in 2001.
The song has been described as post-metal.
TEMPEST is a National Security Agency specification and NATO certification referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations. TEMPEST covers both methods to spy upon others and also how to shield equipment against such spying. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC).
The NSA methods for spying upon computer emissions are classified, but some of the protection standards have been released by either the NSA or the Department of Defense. Protecting equipment from spying is done with distance, shielding, filtering and masking. The TEMPEST standards mandate elements such as equipment distance from walls, amount of shielding in buildings and equipment, and distance separating wires carrying classified vs. unclassified materials, filters on cables, and even distance and shielding between wires/equipment and building pipes. Noise can also protect information by masking the actual data.
Tempest is Balflare's second album, released in 2006.
