The Wire

The Wire is an American crime drama television series set and produced in and around Baltimore, Maryland. Created and primarily written by author and former police reporter David Simon, the series was broadcast by the cable network HBO in the United States. The Wire premiered on June 2, 2002, and ended on March 9, 2008, comprising 60 episodes over five seasons.

Each season of The Wire introduces a different institution in the city of Baltimore and its relationship to law enforcement, while retaining characters and advancing storylines from previous seasons. In chronological order these institutions are: the illegal drug trade, the seaport system, the city government and bureaucracy, the school system, and the print news media. The large cast consists mainly of character actors who are little known for their other roles, as well as numerous real-life Baltimore and Maryland figures in guest and recurring roles. Simon has said that despite its framing as a crime drama, the show is "really about the American city, and about how we live together. It's about how institutions have an effect on individuals. Whether one is a cop, a longshoreman, a drug dealer, a politician, a judge or a lawyer, all are ultimately compromised and must contend with whatever institution to which they are committed."

Imagine Dragons' lineup consists of lead vocalist Dan Reynolds, guitarist Wayne "Wing" Sermon, bassist Ben McKee and drummer Daniel Platzman. The band gained exposure following the release of their debut studio album, Night Visions (2012) and first single "It's Time". The band's second studio album Smoke + Mirrors reached number one on the Billboard 200, Canadian Albums Chart, and UK Albums Chart.Night Visions peaked at number two on the weekly Billboard 200 and UK Albums Chart. According to Billboard, Imagine Dragons topped the year-end rock rankings for 2013;Billboard named them "The Breakthrough Band of 2013", and Rolling Stone named their single "Radioactive" "the biggest rock hit of the year".MTV called them "the year's biggest breakout band".

Imagine Dragons won two American Music Awards for Favorite Alternative Artist, a Grammy Award for Best Rock Performance, five Billboard Music Awards, and a World Music Award. In May 2014, the band was nominated for a total of fourteen different Billboard Music Awards, including Top Artist of the Year and a Milestone Award, recognizing innovation and creativity of different artists across different genres.

HIDDEN ERROR: Usage of "supporting members" is not recognized

The Script is an Irish pop rock band formed in 2001. The band comprises guitarist and vocalist Danny O'Donoghue, guitarist and vocalist Mark Sheehan and drummer Glen Power. Based in London after signing to Sony Label Group imprint Phonogenic, the band released its eponymous debut album, The Script, in August 2008, featuring the hit songs "The Man Who Can't Be Moved" and "Breakeven (Falling to Pieces)". The album peaked at number one in Ireland and the UK. Their next three albums, Science & Faith (2010), #3 (2012) and No Sound Without Silence (2014), all topped the album charts in Ireland and the UK, while Science & Faith reached number three in the US. Hit singles from the albums include "For the First Time", "Nothing", "Hall of Fame" and "Superheroes".

The Script's music has been featured in popular television programmes such as 90210, Ghost Whisperer, The Hills, Waterloo Road, EastEnders, Made in Chelsea and The Vampire Diaries. Frontman Danny O'Donoghue was also a coach on The Voice UK for seasons 1 and 2, before leaving the show in order to focus more on the band. The band has won three Meteor Ireland Music Awards, two World Music Awards and have received two Brit Award nominations.

Wire

A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.

Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-woundcoil springs, such as the Slinky toy, are made of special flattened wire.

History

In antiquity, jewelry often contains, in the form of chains and applied decoration, large amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes. This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BC most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method. The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. There is some evidence for the use of drawing further East prior to this period.

Passive infrared sensor

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

Operating principles

All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose.

The term passive in this instance refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. They work entirely by detecting the energy given off by other objects. PIR sensors don't detect or measure "heat"; instead they detect the infrared radiation emitted or reflected from an object.

Construction

Infrared radiation enters through the front of the sensor, known as the 'sensor face'. At the core of a PIR sensor is a solid state sensor or set of sensors, made from pyroelectric materials—materials which generate energy when exposed to heat. Typically, the sensors are approximately 1/4 inch square (40 mm²), and take the form of a thin film. Materials commonly used in PIR sensors include gallium nitride (GaN), caesium nitrate (CsNO₃), polyvinyl fluorides, derivatives of phenylpyridine, and cobalt phthalocyanine. The sensor is often manufactured as part of an integrated circuit.
