Afterglow

An afterglow is a broad high arch of whitish or rosy light appearing in the sky due to very fine particles of dust suspended in the high regions of the atmosphere. An afterglow may appear above the highest clouds in the hour of deepening twilight, or reflected from the high snowfields in mountain regions long after sunset. The particles produce a scattering effect upon the component parts of white light. The true alpenglow, which occurs long after sunset or long before sunrise, is caused by the backscattering of red sunlight by aerosols and fine dust particles low in the atmosphere. It is an afterglow caused by direct illumination of atmospheric particles by sunlight as it refracts and gets scattered through the earth's atmosphere. The high-energy and high-frequency light is scattered out the most and the remaining low-energy, low-frequency reaches the observer in the horizon at twilight. The backscattering of this light further turns it pinkish-red. This period of time is referred to as the blue hour and is widely treasured by photographers and painters as it offers breathtaking imagery. The afterglow persists till the earth's shadow (terminator line) takes over the sky of the observer as nightfall and the stars appear, with planet Venus being the brightest star visible in the night sky just opposite to the Belt of Venus at the anti-solar point.

Afterglow (Wilkinson song)

"Afterglow" is a song by the British record producer Wilkinson. It features uncredited vocals from Becky Hill. It was released on 13 October 2013, through RAM Records, as the fourth single from his debut album Lazers Not Included. It entered the UK Singles Chart at number 8 and topped the UK Dance Chart on 20 October 2013. Wilkinson and Hill performed the song as well as a cover of One Republic's "Counting Stars" in BBC Radio 1's Live Lounge on 17 October 2013. On 17 January 2014, the song was certified as silver in the United Kingdom for over 200,000 sales.

Music video

A music video to accompany the release of "Afterglow" was first released onto YouTube on 10 September 2013 at a total length of two minutes and fifty-two seconds. The video details a couple's five years of dating by tabulating the numbers, hours, days, and statistics of what they have done together since they first met. Australian actor, Leighton Sharpe, plays the role of Paul in the video and Danish model, Ida Marie, plays the role of Dana.

Municipal solid waste

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and as refuse or rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately.

Composition

The composition of municipal solid waste varies greatly from municipality to municipality (country to country) and changes significantly with time. In municipalities (countries) which have a well developed waste recycling system, the waste stream consists mainly of intractable wastes such as plastic film, and unrecyclable packaging materials. At the start of the 20th century, the majority of domestic waste (53%) in the UK consisted of coal ash from open fires. In developed municipalities (countries) without significant recycling activity it predominantly includes food wastes, market wastes, yard wastes, plastic containers and product packaging materials, and other miscellaneous solid wastes from residential, commercial, institutional, and industrial sources. Most definitions of municipal solid waste do not include industrial wastes, agricultural wastes, medical waste, radioactive waste or sewage sludge. Waste collection is performed by the municipality within a given area. The term residual waste relates to waste left from household sources containing materials that have not been separated out or sent for reprocessing. Waste can be classified in several ways but the following list represents a typical classification:

Garbage (EP)

Garbage is the fourth EP by British Electronic music duo Autechre, released by Warp Records on 27 February 1995. Garbage is a companion to their album Amber, being based on material from the same sessions. The cover and interior illustrations are digitally garbled versions of the cover of Amber.

Garbage was also released alongside Anvil Vapre as part of the US version of Tri Repetae, and as a part of the EPs 1991–2002 compilation.

Track listing

On the EP (but not on EPs 1991—2002) the tracks are written as "Garbagemx36"/"PIOBmx19"/"Bronchusevenmx24"/"VLetrmx21". The numbers at the end of the track titles are the percentage of the total EP time each track takes up, with the total being 100.

Garbage (computer science)

Garbage, in the context of computer science, refers to objects, data, or other regions of the memory of a computer system (or other system resources), which will not be used in any future computation by the system, or by a program running on it. As computer systems all have finite amounts of memory, it is frequently necessary to deallocate garbage and return it to the heap, or memory pool, so the underlying memory can be reused.

Classification

Garbage is generally classified into two types: semantic garbage that is any object or data never accessed by a running program for any combination of program inputs, and syntactic garbage that refers to objects or data within a program's memory space but unreachable from the program's root set. Objects and/or data which are not garbage are said to be live.

Casually stated, syntactic garbage is data that cannot be reached, while semantic garbage is data that will not be reached. More precisely, syntactic garbage is data that is unreachable due to the reference graph (there is no path to it), which can be determined by many algorithms, as discussed in tracing garbage collector and only requires analyzing the data, not the code. Semantic garbage is data that will not be accessed, either because it is unreachable (hence also syntactic garbage), or reachable but will not be accessed; this latter requires analysis of the code, and is in general an undecidable problem.
